<p>I am having trouble with a very simple Perl process. I am basically querying an Oracle database and I want to load it into Excel. I have been able to use DBIx::Dump and it works. However, I need to be able to use a variety of Excel formatting tools. And I think <a href="http://search.cpan.org/dist/Spreadsheet::WriteExcel" rel="nofollow noreferrer">Spreadsheet::WriteExcel</a> is the best module that outputs to Excel that allows me do more formatting. </p>
<p>Below is the code and the error I am getting. I basically query Oracle, fetch the data, load into an array and try to write to Excel. For some reason it is doing some kind of comparison and it does not like the data types. For example, the date is '25-OCT-08'. The SVP is 'S01'. It seems to be saying that they are not numeric. </p>
<p>Error:</p>
<pre><code>Argument "01-NOV-08" isn't numeric in numeric ge <>=> at C:/Perl/site/lib/Spreadsheet/WriteExcel/Worksheet.pm line 3414.

<p>I am launching a child process with ProcessBuilder, and need the child process to exit if the parent process does. Under normal circumstances, my code is stopping the child properly. However, if I cause the OS to kill the parent, the child will continue running.</p>
<p>Is there any way to "tie" the child process to the parent, such that it'll exit when the parent is killed?</p>

<p>There are two schools of thought on how to best extend, enhance, and reuse code in an object-oriented system:</p>
<ol>
<li><p>Inheritance: extend the functionality of a class by creating a subclass. Override superclass members in the subclasses to provide new functionality. Make methods abstract/virtual to force subclasses to "fill-in-the-blanks" when the superclass wants a particular interface but is agnostic about its implementation.</p></li>
<li><p>Aggregation: create new functionality by taking other classes and combining them into a new class. Attach an common interface to this new class for interoperability with other code.</p></li>
</ol>
<p>What are the benefits, costs, and consequences of each? Are there other alternatives?</p>
<p>I see this debate come up on a regular basis, but I don't think it's been asked on
Stack Overflow yet (though there is some related discussion). There's also a surprising lack of good Google results for it. </p>

<p>I'm trying to build a HQL that can left join values from a collection, in order to give me the chance of checking "is null" on it.</p>
<p>Taken from the example from hibernate manual:</p>
<pre>
from Cat as cat
left join cat.kittens as kitten
with kitten.bodyWeight > 10.0
</pre>
<p>doesn't seem to work in NHibernate, since it doesn't recognize the "with" keyword. How else are you supposed to left join and check for no-matching entries if you cannot specify join-clauses directly in your join as opposed to in your WHERE-statement?</p>
<p>I'm running NHibernate 2.0.0.</p>

<p>With the jQuery datepicker, how does one change the year range that is displayed? On the jQuery UI site it says the default is "10 years before and after the current year are shown". I want to use this for a birthday selection and 10 years before today is no good. Can this be done with the jQuery datepicker or will I have to use a different solution?</p>

<p>In Python map() works on any data that follows the sequence protocol. It does The Right Thing^TM whether I feed it a string or a list or even a tuple.</p>
<p>Can't I have my cake in OCaml too? Do I really have no other choice but to look at the collection type I'm using and find a corresponding List.map or an Array.map or a Buffer.map or a String.map? Some of these don't even exist! Is what I'm asking for unusual? I must be missing something.</p>

<p>I have two html pages, when you click on something on the first html, it will go to the second one. What I want to do is to show text according to what you clicked on the first html. different texts are wrapped with different ids. Here's how I wrote:</p>
<pre><code><a href="secondpage.html#one"></a>
<a href="secondpage.html#two"></a>
<a href="secondpage.html#three"></a>
</code></pre>
<p>I'm expecting to see two.html load the text with id "one", but it doesn't work, does anyone know what I did wrong? </p>
<p>Here's the code on second page:</p>
<pre><code><ul id="menu" class="aaa">
<li><a id="one" href="#">one</a></li>
<li><a id="two" href="#">two</a></li>
<li><a id="three" href="#">three</a></li>
</ul>
</code></pre>
<p>And I have a JS file to modify each id:</p>
<pre><code>$("one").observe('click', function() {
$('Pic').writeAttribute('src',"picone.jpg");
$('Bio').update("texthere!");
});
</code></pre>
<p>Same for two and three.</p>
<p>Right now if I click on a button on the first page, it will always show
the text and pic for "one", no matter which button I click.</p>
<p>But I want to see the pic and text for "two" if i click on it.</p>

<p>I am working on a small parser that should accept input in a number of languages. I am going to have maybe 50 strings that will serve as keywords/anchors in parsing the input. In PHP, what would be the best way to organize these translated keywords? </p>
<p>One possible solution that comes to my mind is to use an associative array. Like this:</p>
<pre><code>$lang = array('us' => array('totalDebt' => 'Total Debt', 'color' => 'Color'),
'gb' => array('totalDebt' => 'Total Debt', 'color' => 'Colour'))
</code></pre>
<p>which I could then access using the following:</p>
<pre><code>$langCode = 'en';
$debtPos = strpos($lang[$langCode]['totalDebt']);
</code></pre>
<p>Are there any better, proven methods for dealing with a bunch of short strings translated into a bunch of languages?</p>

<p>I want to get the method <code>System.Linq.Queryable.OrderyBy<T, TKey>(the IQueryable<T> source, Expression<Func<T,TKey>> keySelector)</code> method, but I keep coming up with nulls.</p>
<pre><code>var type = typeof(T);
var propertyInfo = type.GetProperty(group.PropertyName);
var propertyType = propertyInfo.PropertyType;
var sorterType = typeof(Func<,>).MakeGenericType(type, propertyType);
var expressionType = typeof(Expression<>).MakeGenericType(sorterType);
var queryType = typeof(IQueryable<T>);
var orderBy = typeof(System.Linq.Queryable).GetMethod("OrderBy", new[] { queryType, expressionType }); /// is always null.
</code></pre>
<p>Does anyone have any insight? I would prefer to not loop through the <code>GetMethods</code> result.</p>

<p>I am attempting to return a collection of departments from a .NET assembly to be consumed by ASP via COM Interop. Using .NET I would just return a generic collection, e.g. <code>List<Department></code>, but it seems that generics don't work well with COM Interop. So, what are my options?</p>
<p>I would like to both iterate over the list and be able to access an item by index. Should I inherit from <code>List<Department></code>, implement an <code>IList</code>, <code>IList<Department></code> or another interface, or is there a better way? Ideally I would prefer not to have to implement a custom collection for every type of list I need. Also, will <code>List[index]</code> even work with COM Interop?</p>
<p>Thanks,
Mike</p>
<h2>Example .NET components (C#):</h2>
<pre><code>public class Department {
public string Code { get; private set; }
public string Name { get; private set; }
// ...
}
public class MyLibrary {
public List<Department> GetDepartments() {
// return a list of Departments from the database
}
}
</code></pre>
<h2>Example ASP code:</h2>
<pre><code><%
Function PrintDepartments(departments)
Dim department
For Each department In departments
Response.Write(department.Code & ": " & department.Name & "<br />")
Next
End Function
Dim myLibrary, departments
Set myLibrary = Server.CreateObject("MyAssembly.MyLibrary")
Set departments = myLibrary.GetDepartments()
%>
<h1>Departments</h1>
<% Call PrintDepartments(departments) %>
<h1>The third department</h1>
<%= departments(2).Name %>
</code></pre>

<p>I just spent half an one our to find out what caused the Error-Message "Ci is not defined" in my JavaScript code. I finally found the reason:</p>
<p>It should be (jQuery):</p>
<pre><code>$("asd").bla();
</code></pre>
<p>It was:</p>
<pre><code>("asd").bla();
</code></pre>
<p>(Dollar sign gone missing)</p>
<p>Now after having fixed the problem I'd like to understand the message itself: What does Firefox mean when it tells me that "Ci" is not defined. What's "Ci"?</p>
<hr>
<p>Update:
I'm using the current version of Firefox (3.0.3).</p>
<p>To reproduce, just use this HTML code:</p>
<pre><code><html><head><title>test</title>
<script>
("asd").bla();
</script>
</head><body></body></html>
</code></pre>
<p>To make it clear: I know what caused the error message. I'd just like to know what Firefox tries to tell me with "Ci"...</p>

<p>I have a file I need to rename to that of an existing file. This is a copy, modify, replace original operation on an existing JAR file. I've got the first two steps done, I just need help with the replace original bit. What's the best way to rename the new version of the JAR to that of the old. The old JAR doesn't need preserving and I don't want to have a copy of the new with its initial name sticking around. </p>
<p>I have commons lang and io already, so if there's a method I've missed, that would be great.</p>

<p>I'm looking to convert a small .NET console application into a Windows Service. I'd like to build two versions, one using .NET 2.0 and another with .NET 3.5 .</p>
<p>Are there radically different approaches that need to be taken, or will the 2.0 version be roughly equivalent to the 3.5 version? Where's a good source of information (i.e. a web-based guide) that can walk me through the steps of setting up the service?</p>
<p>Thanks!
P.A.</p>

<p>I've got an MS access database and I would need to create an SQL query that allows me to select all the not distinct entries in one column while still keeping all the values.</p>
<p>In this case more than ever an example is worth thousands of words:</p>
<p>Table:</p>
<pre><code>A B C
1 x q
2 y w
3 y e
4 z r
5 z t
6 z y
</code></pre>
<p><em>SQL magic</em></p>
<p>Result:</p>
<pre><code>B C
y w
y e
z r
z t
z y
</code></pre>
<p>Basically it removes all unique values of column B but keeps the multiple rows of the
data kept. I can "group by b" and then "count>1" to get the not distinct but the result will only list one row of B not the 2 or more that I need.</p>
<p>Any help?</p>
<p>Thanks.</p>

<p>I just got this error today, the code has been working until this afternoon I published the latest version to our server and it broke with that error both locally and on the server. I don't use "DataSourceID", the application reads database queries into a datatable and sets the datatable as the DataSource on the GridViews. I did a search in Visual Studio, searching the entire solution and the string "DataSourceID" does not appear in even 1 line of code in the entire solution. This is the first thing that freaked me out. </p>
<p>I figure it had been working yesterday, so I reverted the code to yesterday's build. The error was still there. I kept going back a build, and still the issue is there. I went back a month, I am still getting the same error. This application was working fine this morning? There has really been no code changes, and no where in the application is the DataSourceID EVER set on any of the gridviews. Has anyone ever seen anything like this at all??</p>
<p>How can I get that error if DataSourceID is never set... and the word "DataSourceID" is not in my solution? I just did a wingrep on the entire tree doing a case insensitive search on datasourceid.... pulled up absolutely nothing. That word is absolutely no where in the entire application. </p>
<pre><code> <asp:GridView ID="grdCommunication" runat="server"
Height="130px" Width="100%"
AllowPaging="true" >
... standard grid view column setup here...
</asp:GridView>
// Code behind.. to set the datasource
DataSet dsActivity = objCompany.GetActivityDetails();
grdCommunication.DataSource = dsActivity;
grdCommunication.DataBind();
</code></pre>
<p>// Updated: removed some confusing notes. </p>

<p>I am rather new to complex CSS, and have a question- I have a page which positions a floating element along the bottom of the page. It does so by setting the Bottom: 0, and Position: Absolute. </p>
<p>When the user resizes their browser to a very-small size, this element covers up other content on the page.</p>
<p>Ideally, The element would continue to float at the bottom of the browser at normal and large sizes, but if the browser window were to be shrunk too small, the browser would force a scrollbar, instead of moving the floating element any further.</p>
<p>Essentially, I want to tell the browser- No matter how small the window is, never render the page smaller than 800x600. </p>

<p>Upon a click on an IMG, I would like to get to the next subsequent DIV so that the DIVs content can either be displayed or hidden depending on its current display state.</p>
<p>This is an HTML snippet:</p>
<pre><code><div>
<span class="expand"><img src="images/plus.gif"></span>
<span>Subject Heading</span>
</div>
<div class="record hidden">Display or Hide this text</div>
</code></pre>
<p>I have some code (<a href="https://stackoverflow.com/questions/123401/using-jquery-to-find-the-next-table-row#123518">provided in another answer on this site</a>) for doing this in a table. Would I set an event listener for the img or the containing span? not sure how to use parent(), next(), sibling() functions to get around....</p>
<p>Also, how do you test if your navigation is getting to the right element? can you use an alert to display the id or value?</p>
<p>Any help is appreciated
Thanks</p>

<p>I want to alert the user in a Swing application of certain events with an old fashioned PC Speaker beep (NOT the soundcard), since not on every PC there is a soundcard with an attached speaker, or volume might be turned to zero, or a headphone might be connected... How can I do this?</p>
<p>UPDATE:
java.awt.Toolkit.getDefaultToolkit().beep() seems usually to generate a sound on the soundcard. It only uses the speaker if there is no active soundcard.
To print an ASCII value 7 works only if the application is launched in a terminal, which at least a Swing app usually isn't.
So the question is still open.</p>

<p>Does anyone know how to iterate over a generic list if the type of that list isn't known until runtime?</p>
<p>For example, assume <code>obj1</code> is passed into a function as an <code>Object</code>:</p>
<pre><code>Dim t As Type = obj1.GetType
If t.IsGenericType Then
Dim typeParameters() As Type = t.GetGenericArguments()
Dim typeParam As Type = typeParameters(0)
End If
</code></pre>
<p>If <code>obj</code> is passed as a <code>List(Of String)</code> then using the above I can determine that a generic list (<code>t</code>) was passed and that it's of type <code>String</code> (<code>typeParam</code>). I know I am making a big assumption that there is only one generic parameter, but that's fine for this simple example.</p>
<p>What I'd like to know is, based on the above, how do I do something like this:</p>
<pre><code>For Each item As typeParam In obj1
'do something with it here
Next
</code></pre>
<p>Or even something as simple as getting <code>obj1.Count()</code>.</p>

<p>Either for comparisons or initialization of a new variable, does it make a difference which one of these you use?</p>
<p>I know that BigDecimal.ZERO is a 1.5 feature, so that's a concern, but assuming I'm using 1.5 does it matter?</p>
<p>Thanks.</p>

<p>Any ideas for the simplest queries I could run using MySQLdb to create a deadlock condition would be?</p>

<p>I have a clock feature in a VB.NET program that displays the time including the seconds. I currently have a timer constantly polling using NOW. I have to poll the system clock quite often because I need to have the second update in sync with the system clock.</p>
<p>Is there a more direct to access the time only when the seconds change?</p>
<p>Is there a more efficient way to write this code?</p>
<p>If you need more info let me know.</p>

<p>I have an app with the following basic architecture:</p>
<p>A windows service (Service) that registers a .NET type (RemoteObject) for remote access (.NET Remoting). RemoteObject creates non-ThreadPool threads that use the ThreadPool to do IO processing. The size of the ThreadPool must be restricted to a limit for a particular reason. A GUI app uses .NET Remoting to access RemoteObject. </p>
<p>I've noticed that if the size of the ThreadPool is too low, the GUI app will hang when making a call to RemoteObject.</p>
<p>My question is, how can I figure out why this is hanging, and why would the RemoteObject thread be affected by the ThreadPool?</p>
<p>This is driving me crazy; thank you for your help!</p>

<p>We have a current application where user login credentials are stored in a SQL Server DB. These are, basically, stored as a plain text username, a password hash, and an associated salt for this hash.</p>
<p>These were all created by built in functions in ASP.NET's membership/role system. Here's a row for a user named 'joe' and a password of 'password':</p>
<blockquote>
<p>joe,kDP0Py2QwEdJYtUX9cJABg==,OJF6H4KdxFLgLu+oTDNFodCEfMA=</p>
</blockquote>
<p>I've dumped this stuff into a CSV file and I'm attempting to get it into a usable format for Django which stores its passwords in this format:</p>
<p>[algo]$[salt]$[hash]</p>
<p>Where the salt is a plain string and the hash is the hex digest of an SHA1 hash.</p>
<p>So far I've been able to ascertain that ASP is storing these hashes and salts in a base64 format. Those values above decode into binary strings.</p>
<p>We've used reflector to glean how ASP authenticates against these values:</p>
<pre><code>internal string EncodePassword(string pass, int passwordFormat, string salt)
{
if (passwordFormat == 0)
{
return pass;
}
byte[] bytes = Encoding.Unicode.GetBytes(pass);
byte[] src = Convert.FromBase64String(salt);
byte[] dst = new byte[src.Length + bytes.Length];
byte[] inArray = null;
Buffer.BlockCopy(src, 0, dst, 0, src.Length);
Buffer.BlockCopy(bytes, 0, dst, src.Length, bytes.Length);
if (passwordFormat == 1)
{
HashAlgorithm algorithm = HashAlgorithm.Create(Membership.HashAlgorithmType);
if ((algorithm == null) && Membership.IsHashAlgorithmFromMembershipConfig)
{
RuntimeConfig.GetAppConfig().Membership.ThrowHashAlgorithmException();
}
inArray = algorithm.ComputeHash(dst);
}
else
{
inArray = this.EncryptPassword(dst);
}
return Convert.ToBase64String(inArray);
}
</code></pre>
<p>Eseentially, pulls in the salt from the DB and b64 decodes it into a binary representation. It does a "GetBytes" on the raw password and then it concatinates them, salt first.</p>
<p>It then runs the SHA1 algorithm on this new string, base64 encodes it, and compares it against the value stored in the database.</p>
<p>I've attempted to write some code to try and reproduce these hashes in Python and I'm failing. I won't be able to use them in Django until I can figure out how this translates over. Here's how I'm testing:</p>
<pre><code>import hashlib
from base64 import b64decode, b64encode
b64salt = "kDP0Py2QwEdJYtUX9cJABg=="
b64hash = "OJF6H4KdxFLgLu+oTDNFodCEfMA="
binsalt = b64decode(b64salt)
password_string = 'password'
m1 = hashlib.sha1()
# Pass in salt
m1.update(binsalt)
# Pass in password
m1.update(password_string)
# B64 encode the binary digest
if b64encode(m1.digest()) == b64hash:
print "Logged in!"
else:
print "Didn't match"
print b64hash
print b64encode(m1.digest())
</code></pre>
<p>I'm wondering if anyone can see any flaws in my approach or can suggest an alternate method. Perhaps you can take the algorithms above and the known password and salt above and produce the hash on your system?</p>

<p>I'm looking for a good way to run a Apache Derby server in network mode. I'm using the NetworkServerControl to start the server and it's working great.</p>
<p>I start the server like this:</p>
<pre><code>/**
* starts the network server
* @return true if sucessfull
*/
public boolean start()
{
try
{
// just to be sure that we don't start two servers
this.stop();
server = new NetworkServerControl();
server.start( null );
return true;
}
catch ( Exception ex )
{
this.logLogger.debug( ex );
return false;
}
}
</code></pre>
<p>And stop it like this:</p>
<pre><code>/**
* stops the server
*
* @return true if there were no problems stopping the server
*/
public boolean stop()
{
try
{
if ( server == null )
{
server = new NetworkServerControl();
}
server.shutdown();
return true;
}
catch ( Exception ex )
{
this.logLogger.debug( ex );
return false;
}
}
</code></pre>
<p>On the main() I have this so the process doesn't die while the server is running</p>
<pre><code>(...)
clsDB.start();
while( clsDB.testForConnection() )
{
Thread.sleep( 60000 );
}
</code></pre>
<p>testForConnection() looks like this:</p>
<pre><code>/**
* Try to test for a connection
*
* @return true if the server is alive
*/
public boolean testForConnection()
{
try
{
server.ping();
return true;
}
catch ( Exception ex )
{
this.logLogger.debug( ex );
return false;
}
}
</code></pre>
<p>My problem is that when a new instace of my JAR is called the old one will still be running (unless I'm really really lucky and the test is made before the new server is started).</p>
<p>I know I could just test if the server is already running and then I wouldn't start again, but I would like for start to work like a restart if the server is already there.</p>

<p>According to <a href="http://en.wikipedia.org/wiki/Rounding" rel="noreferrer">Wikipedia</a> when rounding a negative number, you round the absolute number. So by that reasoning, -3.5 would be rounded to -4. But when I use java.lang.Math.round(-3.5) returns -3. Can someone please explain this?</p>

<p>We are using feature branches in Subversion for our development which is a very convenient way of keeping code within version control that is not yet ready for the mainline. However, whenever I go to merge the feature branch revision into the mainline it is a pain. Right now I go through the following steps:</p>
<ol>
<li>Check out the original feature branch revision to a new directory</li>
<li>Perform a difference between my current development and the original feature branch directories with a tool like Beyond Compare</li>
<li>Check out the current mainline revision to a new directory</li>
<li>Merge the new/changed files into the current mainline directory.</li>
<li>Perform a difference using my IDE to ensure all of the files are properly checked out/added to subversion</li>
<li>Compile and test</li>
<li>Commit</li>
</ol>
<p>It seems to me that there is a lot of room for errors in this process and it makes me nervous every time I walk through the steps. Granted, everything is checked into Subversion on my feature branch, so a mistake at any step is recoverable. </p>
<p>I believe that Subversion 1.5 has a way to merge a branch into the mainline, but we are still using Subversion 1.4. What are other people using to simplify the steps of merging a feature branch in Subversion into their mainline development? Are you using different tools? Are you utilizing the merging feature in Subversion 1.5?</p>

<div style="width: 400px;">SomeContent</div>
</td>
</code></pre>
<p>For some reason, the column that contains a div will not expand to 500px as the style suggests.</p>
<p>Do you know how to get the td to honor the width that I am specifying in the style?</p>

<p>I am using a custom item renderer in a combobox to display a custom drawing instead of the default text label.</p>
<p>This works fine for the dropdown list but the displayed item ( when the list is closed) is still the textual representation of my object.</p>
<p>Is there a way to have the displayed item rendered the same way as the one in the dropdown?</p>

<p>I've got a solution which I setup / cleanup using batch files ...
- there are a pair of MSMQ ports, send and receive, with another application on the end of the queues</p>
<p>I'm finding I can't properly stop the orchestration in the batch file ... the error is the send port is unenlisted
- I'm using the StopOrch.vbs script from the SDK samples</p>
<p>But I can go into BizTalk Admin Console and manually stop the orchestration with Full Terminate Ok</p>
<p>The setup / cleanup works Ok if I don't actually push any messages down the MSMQ queues</p>

<p>Is there an easy way to convert a string that contains this:</p>
<pre><code>Date: Wed, 5 Nov 2008 13:12:12 -0500 (EST)
</code></pre>
<p>into a string that contains this:</p>
<pre><code>20081105_131212
</code></pre>
<p><strong>UPDATE:</strong><br>
I ended up using date.tryparse which is similar to tryParseExact except you don't have to specify the format string. I did have to eliminate the () and the EST for this to work. The date string will always be EST because the date string comes from 1 web server.</p>
<p>Original string: <br></p>
<pre><code>Date: Wed, 5 Nov 2008 13:12:12 -0500 (EST)
</code></pre>
<p>Using this code: <br></p>
<pre><code>buff1.Remove(0, 6).Replace("(", "").Replace(")", "").Replace("EST", "").Trim()
</code></pre>
<p>Becomes this string: <br></p>
<pre><code>Wed, 5 Nov 2008 13:12:12 -0500
</code></pre>
<p>Then I can format appropriately to generate my filename date using this:</p>
<pre><code> If Date.TryParse(buff1, dateValue) Then
MsgBox(Format(dateValue, "yyyyMMdd_HHmmss"))
Else
MsgBox("nope")
End If
</code></pre>

<p>I have a really simple WPF UserControl:</p>
<pre><code><UserControl x:Class="dr.SitecoreCompare.WPF.ConnectionEntry"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
x:Name="connEntry"
BorderBrush="Navy" BorderThickness="1" Margin="5,0,0,5" >
<StackPanel Margin="0,10,0,0" >
<Label FontWeight="ExtraBold" Content="{Binding ElementName=connEntry, Path=Title}"></Label>
<Label Margin="0,5,0,0">Server:</Label>
<TextBox x:Name="txtServer" TabIndex="1" Text="{Binding Path=ServerName}" ></TextBox>
<Label>Database:</Label>
<TextBox x:Name="txtDatabase" TabIndex="2" Text="{Binding Path=DatabaseName}"></TextBox>
</StackPanel>
</code></pre>
<p></p>
<p>This is used twice in the same window. Now, I can select the first TextBox on both th instances of my UserControl, but the second ("txtDatabase") textbox cannot be selected, neither by tabbing or clicking. Why is this ? Am I missing something with regards to creating WPF usercontrols ? </p>
<p>EDIT:
DatabaseName is not readonly, it is a simple property. The XAML for the window the usercontrol is placed on looks like this:</p>
<pre><code><Window x:Class="dr.SitecoreCompare.WPF.ProjectDialog"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:c="clr-namespace:dr.SitecoreCompare.WPF"
Title="Choose project" Height="280" Width="500"
WindowStartupLocation="CenterOwner" WindowStyle="SingleBorderWindow" HorizontalAlignment="Center" ShowInTaskbar="False" ShowActivated="True" ResizeMode="NoResize" VerticalContentAlignment="Top" VerticalAlignment="Center">
<StackPanel>
<Label>Choose databases</Label>
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition />
<ColumnDefinition />
</Grid.ColumnDefinitions>
<c:ConnectionEntry Grid.Column="0" x:Name="connMaster" Title="Master:" Padding="5" />
<c:ConnectionEntry Grid.Column="1" x:Name="connSlave" Title="Slave:" Padding="5" />
</Grid>
<StackPanel Orientation="Horizontal" HorizontalAlignment="Right" Margin="0,0" >
<Button x:Name="btnCancel" Click="btnCancel_Click">Cancel</Button>
<Button x:Name="btnOK" Click="btnOK_Click">OK</Button>
</StackPanel>
</StackPanel>
</Window>

<p>I have this code:</p>
<pre><code>CCalcArchive::CCalcArchive() : m_calcMap()
{
}
</code></pre>
<p><code>m_calcMap</code> is defined as this:</p>
<pre><code>typedef CTypedPtrMap<CMapStringToPtr, CString, CCalculation*> CCalcMap;
CCalcMap& m_calcMap;
</code></pre>
<p>When I compile in Visual Studio 2008, I get this error:</p>
<pre><code>error C2440: 'initializing' : cannot convert from 'int' to 'CCalcArchive::CCalcMap &'
</code></pre>
<p>I don't even understand where it gets the "int" error from, and also why this doesn't work? It feels like I'm actually having some sort of syntax error, but isn't this how member initialization lists are supposed to be used? Also, AFAIK, the MFC class <code>CTypedPtrMap</code> has no constructor taking arguments.</p>

<p>I'm trying to look for the source of the <code>datetime</code> module in particular, but I'm interested in a more general answer as well.</p>

<p>I have been trying to parse Java exceptions that appear in a log for some code I'm working with. My question is, do you parse the exception trace from the top down, or the bottom up? It looks something like this:</p>
<pre><code>ERROR [main]</b> Nov/04 11:03:19,440 [localhost].[/BookmarksPortlet].[] - Exception sending context...
org.springframework.beans.factory.BeanCreationException: Error creating bean...: Cannot Resolve reference...: Error creating bean... nested exception... nested exception is org.hibernate.HibernateException: Dialect class not found: org.hibernate.dialect.Oracle10gDialect
Caused by:
... [similar exceptions and nested exceptions]
...
at [start of stack trace]
</code></pre>
<p>Something like that. Obviously, I'm not looking for the answer to this specific exception, but how do you go about parsing an exception trace like this? Do you start at the top level error, or do you start at the inner most error (under the "caused by" clauses)?</p>
<p>The problem is more difficult for me because I'm not working with code I wrote. I'm editing the XML configurations, so I'm not really even looking the Java code. In my own code, I would recognize locations in the trace and would know what sort of things to look for. So how do you approach an exception like this in general?</p>

<p>There are all sorts of advantages to using Emacs, but for someone comfortable with the usual Win32 applications it comes with a wall-like learning curve. With most other editors it’s possible to just start using them and then learn about their other features and enhancements as you go along. </p>
<p>How to just get on with using Emacs straight away, with the aim of reaching that point where you actually prefer to use Emacs over other editors or applications?</p>
<p>Edit - To try and clarify the question: I’ve done the tutorial, read some docs, etc. then soon after when I’ve wanted to quickly edit some text it’s been easier to just use another editor, that I already know. What do I need to do so that not only I don’t just go for another easier editor, but that I actually prefer to use Emacs, and how to get here as quickly as possible? What if any are the training wheels for Emacs?</p>

<p>I have a class derived from <code>CTreeCtrl</code>. In <code>OnCreate()</code> I replace the default <code>CToolTipCtrl</code> object with a custom one:</p>
<pre><code>int CMyTreeCtrl::OnCreate(LPCREATESTRUCT lpCreateStruct)
{
if (CTreeCtrl::OnCreate(lpCreateStruct) == -1)
return -1;
// Replace tool tip with our own which will
// ask us for the text to display with a TTN_NEEDTEXT message
CTooltipManager::CreateToolTip(m_pToolTip, this, AFX_TOOLTIP_TYPE_DEFAULT);
m_pToolTip->AddTool(this, LPSTR_TEXTCALLBACK);
SetToolTips(m_pToolTip);
// Update: Added these two lines, which don't help either
m_pToolTip->Activate(TRUE);
EnableToolTips(TRUE);
return 0;
}
</code></pre>
<p>My message handler looks like this:</p>
<pre><code>ON_NOTIFY_EX(TTN_NEEDTEXT, 0, &CMyTreeCtrl::OnTtnNeedText)
</code></pre>
<p>However I never receive a <code>TTN_NEEDTEXT</code> message. I had a look with Spy++ and it also looks like this message never gets sent.</p>
<p>What could be the problem here?</p>
<h2>Update</h2>
<p>I'm not sure whether this is relevant: The <code>CTreeCtrl</code>'s parent window is of type <code>CDockablePane</code>. Could there be some extra work needed for this to work?</p>

<p>So odd situation that I ran into today with OrderBy:</p>
<pre><code>Func<SomeClass, int> orderByNumber =
currentClass =>
currentClass.SomeNumber;
</code></pre>
<p>Then:</p>
<pre><code>someCollection.OrderBy(orderByNumber);
</code></pre>
<p>This is fine, but I was going to create a method instead because it might be usable somewhere else other than an orderBy.</p>
<pre><code>private int ReturnNumber(SomeClass currentClass)
{
return currentClass.SomeNumber;
}
</code></pre>
<p>Now when I try to plug that into the OrderBy:</p>
<pre><code>someCollection.OrderBy(ReturnNumber);
</code></pre>
<p>It can't infer the type like it can if I use a Func. Seems like to me they should be the same since the method itself is "strongly typed" like the Func.</p>
<p>Side Note: I realize I can do this:</p>
<pre><code>Func<SomeClass, int> orderByNumber = ReturnNumber;
</code></pre>

<p>I've uploaded a bunch of images to Amazon S3, and now want to add a Cache-Control header to them. </p>
<p>Can the header be updated without downloading the entire image? If so, how?</p>

<p>According to the help file that comes with the Spring.NET framework, you can inject a dependancy defined in the local file by using an 'idref' tag along with a 'local' attribute. </p>
<p>I have been trying to do this with no success and was hoping someone had the experience to help me out. </p>
<p>Below I have a snippet from the config where I am passing it as a constructor argument, but I have tried setting it as a property as well. Both methods seem to yield the same error.</p>
<pre><code><object id="theTargetObject" type="TestClassLibrary.TargetObject, TestClassLibrary"/>
<object id="theClientObject" type="TestClassLibrary.ClientObject, TestClassLibrary">
<constructor-arg name="myClass">
<idref local="theTargetObject"/>
</constructor-arg>
</object>
</code></pre>
<p>Error creating context 'spring.root': Error creating object with name 'theClientObject' defined in 'file [C:\Test\TestApp\bin\Debug\my.config.xml]' : Unsatisfied dependency expressed through constructor argument with index 0 of type [TestClassLibrary.TargetObject] : Could not convert constructor argument value [theTargetObject] to required type [TestClassLibrary.TargetObject] : Cannot convert property value of type [System.String] to required type [TestClassLibrary.TargetObject] for property ''.</p>

<p>So I'm looking for a pattern like this:</p>
<blockquote>
<p>size='0x0'</p>
</blockquote>
<p>In a log file, but I'm only interested in large sizes (4 digits or more). The following regex works great in EditPadPro (nice tool BTW)</p>
<pre><code>size='0x[0-9a-fA-F]{4,}
</code></pre>
<p>But the same RegEx does not work in awk - seems like the repetition <code>{4,}</code> is messing it up. Same with WinGrep - any idea from the RegEx gurus? Thanks!</p>

<p>I've always done web apps and now I need to do a console app. I need to use both an odbc connection and a regular connection. </p>
<p>In the past I would have used:</p>
<pre><code><add name="LinkConnectionString" connectionString="Data Source=SERENITY\SQLEXPRESS;Initial Catalog=Link;Integrated Security=True" providerName="System.Data.SqlClient"/>
</code></pre>
<p>In the web.config, however I am not sure how to do the same thing with inline code.
So like string connectionString = @".....";</p>
<p>I have tried multiple combinations, looked online (including connectionstrings.com), but none of them worked. </p>
<p>Can anyone help me out? I want both the odbc and the regular... as they seem different should be different according to the sample ones online (that don't work). </p>

void foo(bar*);
};
// In cpp
void Foo::foo(bar* const pBar) {
//Stuff
}
</code></pre>
<p>The compiler does not complain that the signatures for Foo::foo do not match. However if I had:</p>

<p>I need to store log files and configuration files for my application. Where is the best place to store them?</p>
<p>Right now, I'm just using the current directory, which ends up putting them in the Program Files directory where my program lives.</p>
<p>The log files will probably be accessed by the user somewhat regularly, so <code>%APPDATA%</code> seems a little hard to get to.</p>
<p>Is a directory under <code>%USERPROFILE%\My Documents</code> the best? It needs to work for all versions of Windows, from 2000 forward.</p>

<p>Hopefully this won't be taken as asking the same question twice...</p>
<p>So I'm working on a Flash website (in AS2) which has an outer index swf which loads sub swf files using <code>loadMovie("subfoo1.swf", placeToShowSwf)</code>. These in turn load an xml file which tells it what content to load. Everything works peachy, but we'd like to add a button to the index swf that opens a sub swf file with one or two different values for one or two variables.</p>
<p>Unfortunately, just adding a button that says</p>
<pre><code>loadMovie("foo1.swf", placeToShowSwf);
placeToShowSwf.openProject(x);
</code></pre>
<p>doesn't work, I assume because <code>openProject(x)</code> is called on a file that isn't fully loaded. I know that there's not a problem with the code, because I made a button elsewhere that only calls <code>placeToShowSwf.openProject(x)</code> and there aren't any problems. </p>
<p>I see two solutions, both of which I'm unsure how to do.</p>
<ol>
<li>Change the desired value when the swf file is made, like a constructor for a class. But is there some sort of constructor function for swf files? It'd be really nice just to say <code>loadMovie(new foo1.swf(x), placeToShowSwf)</code> or something equivalent.</li>
<li>Wait until after swf (and probably xml) is loaded, and then call <code>placeToShowSwf.openProject(x)</code>. </li>
</ol>
<p>Anyone got any guidance towards either of these solutions, or perhaps some other way that my pea-like brain has been unable to fathom?</p>

<p>As already discussed in "<a href="https://stackoverflow.com/questions/250151/lua-as-a-general-purpose-scripting-language">Lua as a general-purpose scripting language?</a>" Lua currently probably isn't the best scripting language for the desktop environment.</p>
<p>But what do you think about the future? Will Lua get so popular that there will soon be enough libraries to be able to use it like Python, Ruby or something similar?</p>
<p>Or will it simply stay in it's WoW niche and that's it?</p>

<p>I'm trying to diff two strings to determine whether or not they solely vary in one numerical subset of the string structure; for example,</p>
<pre><code>varies_in_single_number_field('foo7bar', 'foo123bar')
# Returns True, because 7 != 123, and there's only one varying
# number region between the two strings.
</code></pre>
<p>In Python I can use the <code>difflib</code> to accomplish this:</p>
<pre><code>import difflib, doctest
def varies_in_single_number_field(str1, str2):
"""
A typical use case is as follows:
>>> varies_in_single_number_field('foo7bar00', 'foo123bar00')
True
Numerical variation in two dimensions is no good:
>>> varies_in_single_number_field('foo7bar00', 'foo123bar01')
False
Varying in a nonexistent field is okay:
>>> varies_in_single_number_field('foobar00', 'foo123bar00')
True
Identical strings don't *vary* in any number field:
>>> varies_in_single_number_field('foobar00', 'foobar00')
False
"""
in_differing_substring = False
passed_differing_substring = False # There should be only one.
differ = difflib.Differ()
for letter_diff in differ.compare(str1, str2):
letter = letter_diff[2:]
if letter_diff.startswith(('-', '+')):
if passed_differing_substring: # Already saw a varying field.
return False
in_differing_substring = True
if not letter.isdigit(): return False # Non-digit diff character.
elif in_differing_substring: # Diff character not found - end of diff.
in_differing_substring = False
passed_differing_substring = True
return passed_differing_substring # No variation if no diff was passed.
if __name__ == '__main__': doctest.testmod()
</code></pre>
<p>But I have no idea how to find something like <code>difflib</code> for C++. Alternative approaches welcome. :)</p>

<p>I have a script that generates data in csv format which is sent to the user along with a set of headers that tell the browser it is a .csv file. Everything works great when users (left)click on the link to the script, they are presented with a download dialog with the filename ending in .csv and it suggests using excel, or calc, to open it. However, when users right-click and choose Save As it is being saved with the php script name.</p>
<p>Here is the header code:</p>
<pre><code>header("Pragma: public");
header("Expires: 0"); // set expiration time
header("Content-Type: application/force-download");
header("Content-Type: application/octet-stream");
header("Content-Type: application/download");
$val = date("m_d_Y_g_i");
Header('Content-Disposition: attachment; filename="personal_information_'.$val.'.csv"');
</code></pre>
<p>So again, when users left-click it saves the file as personal_information_date.csv; when they right click it saves as download.php. I'm using FF3. Oddly enough, IE7 does not have this problem.</p>
<p>Any ideas?</p>

<p>I wrote a managed C++ class that has the following function:</p>
<pre><code>void EndPointsMappingWrapper::GetLastError(char* strErrorMessage)
{
strErrorMessage = (char*) Marshal::StringToHGlobalAnsi(_managedObject->GetLastError()).ToPointer();
}
</code></pre>
<p>As you can see, this is a simple method to copy the managed string of the last error to the unmanaged world (<code>char*</code>).</p>
<p>From my unmanaged class I call the method like this:</p>
<pre><code>char err[1000];
ofer->GetLastError(err);
</code></pre>
<p>Putting a breakpoint at the managed C++ method shows that the string is successfully translated into the <code>char*</code>. However, once I return to the unmanaged class, the content of <code>err[1000]</code> is lost and it's empty again.</p>

<p>I'm constructing a simple form in ERB but the HTML produced by the text_field tag makes the <em>for</em> attribute in the label tag invalid.</p>
<pre><code><div>
<p><%= label_tag "email[name]", "Name" %></p>
<%= text_field :email, :name, :class => "text_field" %>
</div>
</code></pre>
<p>Produces the HTML</p>
<pre><code><div>
<p><label for="email[name]">Name</label></p>
<input class="text_field" id="email_name" name="email[name]" size="30" type="text" />
</div>
</code></pre>
<p>Which results in the error </p>
<blockquote>
<p>character "[" is not allowed in the
value of attribute "for".</p>
</blockquote>
<p>How do I generate the text with without the nested parameter name email[name] to change the label tag <em>for</em> attribute? Is there an alternative approach that produces valid HTML?</p>

<p>Does anyone know how to stop jQuery fromparsing html you insert through before() and after()? Say I have an element:</p>
<pre><code><div id='contentdiv'>bla content bla</div>
</code></pre>
<p>and I want to wrap it in the following way: </p>
<pre><code><div id='wrapperDiv'>
<div id='beforeDiv'></div>
<div id='contentDiv'>bla content bla</div>
<div id='afterDiv'></div>
</div>
</code></pre>
<p>I use the following jQuery/Javascript </p>
<pre><code>$('#contentDiv').each( function() {
var beforeHTML = "<div id='wrapperDiv'><div id='beforeDiv'></div>";
var afterHTML = "<div id='afterDiv'></div></div>";
$(this).before(beforeHTML);
$(this).after(afterHTML);
}
</code></pre>
<p>This however will not result in the correct wrapping, it will create:</p>
<pre><code><div id='wrapperDiv'>
<div id='beforeDiv'></div>
</div>
<div id='contentDiv'>bla content bla</div>
<div id='afterDiv'></div>
</code></pre>
<p>Using wrap() won't work either since that gets jQuery even more mixed up when using:</p>
<pre><code>$(this).wrap("<div id='wrapperDiv'><div id='beforeDiv'></div><div id='afterDiv'></div></div>");
</code></pre>
<p>How should I solve this?<br>
Thanks in advance!</p>

<p>I'm developing a web app using Java servlet to access Mysql db, how can I get the number of connections to my DB that is currently open ?</p>
<p>Edit :</p>
<p>I tried "show processlist", it showed me : 2695159, but that's not right, I'm just developing this new project, I'm the only user, couldn't have that many processes running, what I want is the number of users accessing <strong>my project's DB</strong>, not the number of all db users, but just the ones logged in to my database which has only one table.</p>

<p>I have a .NET class library containing a class with a method that performs some lengthy operation. When a client calls this method it should perform the lengthy operation on a new thread in order to avoid blocking the caller. But once the method finishes it should execute some code on the main thread. In a WinForms application I could have used the System.Windows.Forms.Control.Invoke method but this is not my case. So how can I achieve this in C#?</p>

<p><strong>EDIT:</strong> I also have access to <a href="http://www.exslt.org/" rel="nofollow noreferrer">ESXLT</a> functions.</p>
<p>I have two node sets of string tokens. One set contains values like these:</p>
<pre><code>/Geography/North America/California/San Francisco
/Geography/Asia/Japan/Tokyo/Shinjuku
</code></pre>
<p>The other set contains values like these:</p>
<pre><code>/Geography/North America/
/Geography/Asia/Japan/
</code></pre>
<p>My goal is to find a "match" between the two. A match is made when any string in set 1 begins with a string in set 2. For example, a match would be made between <strong>/Geography/North America/California/San Francisco</strong> and <strong>/Geography/North America/</strong> because a string from set 1 begins with a string from set 2.</p>
<p>I can compare strings using wildcards by using a third-party extension. I can also use a regular expression all within an Xpath.</p>
<p>My problem is how do I structure the Xpath to select using a function between all nodes of both sets? XSL is also a viable option.</p>
<p>This XPATH:</p>
<pre><code>count($set1[.=$set2])
</code></pre>
<p>Would yield the count of intersection between set1 and set2, but it's a 1-to-1 comparison. Is it possible to use some other means of comparing the nodes?</p>
<p>EDIT: I did get this working, but I am cheating by using some of the other third-party extensions to get the same result. I am still interested in other methods to get this done.</p>

<p>In IIS Manager under Web Service Extensions, ASP.NET v2.0.50727 is set to "Prohibited" by default. I would like to set this to Allow during the install.</p>
<p>I am currently using WiX Version 2.</p>
<p>I have tried using:</p>
<pre><code><Component Id="Allow_WebServiceExtension_ASP.NET_2.0" DiskId="1" Guid="02247363-E423-41E1-AC15-BEF589B65A4D">
<WebServiceExtension Id="WebServiceExtension_ASP.NET_2.0" Allow="yes" File="%SystemRoot%\Microsoft.NET\Framework\[DOTNETFRAMEWORKVER]\aspnet_isapi.dll" Description="ASP.NET v2.0.50727" UIDeletable="no" />
</Component>
</code></pre>
<p>This adds a second ASP.NET 2.0.50727 entry and does not enable the first.</p>

<p>I want the log to roll over as long as the application is running, but I want the log to start fresh when the application is restarted.</p>
<p><em>Updated:</em>
Based on <a href="https://stackoverflow.com/questions/269999/how-do-i-make-log4j-clear-a-log-at-startup#270026">erickson's</a> feedback, my appender looks like this:</p>
<pre><code> <appender name="myRFA" class="org.apache.log4j.RollingFileAppender">
<param name="File" value="my-server.log"/>
<param name="Append" value="false" />
<param name="MaxFileSize" value="10MB"/>
<param name="MaxBackupIndex" value="10"/>
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern"
value="%d{ISO8601} %p - %t - %c - %m%n"/>
</layout>
</appender>
</code></pre>
<p>I simply added the following line:</p>
<pre><code><param name="Append" value="false" />
</code></pre>
<p>It now truncates the base log file at startup, but it leaves the rolled files alone.</p>

<p>I am implementing a class to compare directory trees (in C#). At first I implemented the actual comparison in the class's constructor. Like this:</p>
<pre><code>DirectoryComparer c = new DirectoryComparer("C:\\Dir1", "C:\\Dir2");
</code></pre>
<p>But it doesn't feel "right" to do a possible lengthy operation in the constructor. An alternative way is to make the constructor private and add a static method like this:</p>
<pre><code>DirectoryComparer c = DirectoryComparer.Compare("C:\\Dir1", "C:\\Dir2");
</code></pre>
<p>What do you think? Do you expect a constructor to be "quick"? Is the second example better or is it just complicating the usage of the class?</p>
<p><strong>BTW:</strong> </p>
<p>I wont mark any answer as accepted because I don't think there is a correct answer, just preference and taste.</p>
<p><strong>Edit:</strong></p>
<p>Just to clarify my example a little. I'm not only insterested if the directories differs, I'm also interested in how they differ (which files). So a simple int return value wont be enough. The answer by cdragon76.myopenid.com actually is pretty close to what I want (+1 to you).</p>

<p>I'm optimizing some frequently run Perl code (once per day per file). </p>
<p>Do comments slow Perl scripts down? My experiments lean towards no:</p>
<pre><code>use Benchmark;
timethese(20000000, {
'comments' => '$b=1;
# comment ... (100 times)
', 'nocomments' => '$b=1;'});
</code></pre>
<p>Gives pretty much identical values (apart from noise).</p>
<pre><code>Benchmark: timing 10000000 iterations of comments, nocomments...
comments: 1 wallclock secs ( 0.53 usr + 0.00 sys = 0.53 CPU) @ 18832391.71/s (n=10000000)
nocomments: 0 wallclock secs ( 0.44 usr + 0.00 sys = 0.44 CPU) @ 22935779.82/s (n=10000000)
Benchmark: timing 20000000 iterations of comments, nocomments...
comments: 0 wallclock secs ( 0.86 usr + -0.01 sys = 0.84 CPU) @ 23696682.46/s (n=20000000)
nocomments: 1 wallclock secs ( 0.90 usr + 0.00 sys = 0.90 CPU) @ 22099447.51/s (n=20000000)
</code></pre>
<p>I get similar results if I run the comments and no-comments versions as separate Perl scripts.</p>
<p>It seems counter-intuitive though, if nothing else the interpreter needs to read the comments into memory every time.</p>

<p>I'm writing a small GUI app that contains some "editor" functionality, and something that I'd like to let users open a few sample text files to test things out quickly. The easiest way of doing this would be to package a separate zip with the appropriate sample files, and have them open them manually; I'd like to make things a little more user-friendly and allow them to pick the files from inside the application and then run them.</p>
<p>So... what do I use? I initially considered .properties but that doesn't seem terribly well suited for the job...</p>

<p>An application that has been working well for months has stopped picking up the JPA <code>@Entity</code> annotations that have been a part of it for months. As my integration tests run I see dozens of "<code>org.hibernate.MappingException: Unknown entity: com.whatever.OrderSystem</code>" type errors.</p>
<p>It isn't clear to me what's gone wrong here.</p>
<p>I have no <code>hibernate.cfg.xml</code> file because I'm using the Hibernate Entity Manager. Since I'm exclusively using annotations, there are no .hbm.xml files for my entities. My <code>persistence.xml</code> file is minimal, and lives in <code>META-INF</code> as it is supposed to.</p>
<p>I'm obviously missing something but can't put my finger on it.</p>
<p>I'm using hibernate-annotations 3.2.1, hibernate-entitymanager 3.2.1, persistence-api 1.0 and hibernate 3.2.1. hibernate-commons-annotations is also a part of the project's POM but I don't know if that's relevant.</p>
<p>Is there a web.xml entry that has vanished, or a Spring configuration entry that has accidentally been deleted?</p>

<p>What are the main differences between a Linked List and a BinarySearchTree? Is BST just a way of maintaining a LinkedList? My instructor talked about LinkedList and then BST but did't compare them or didn't say when to prefer one over another. This is probably a dumb question but I'm really confused. I would appreciate if someone can clarify this in a simple manner.</p>

<p>I cannot understand how this is possible. Please help!!</p>
<p>I have an app with a trayicon. I want a form to be show when the user double clicks the trayicon. I have a problem where it is possible to get 2 or more forms showing by quickly triple or quadruple clicking the trayicon. The reason I don't want a singleton is that I want the form to be released each time it is closed to save memory, maybe this is not a good idea?</p>
<p>I have a field called m_form1.
I have a method called ShowForm1;
I call the method ShowForm1 on the double-click of the TrayIcon.</p>
<pre><code> private Form1 m_form1;
private void ShowForm1()
{
if (m_form1 == null)
{
Trace.WriteLine("*CREATE*" + Thread.CurrentThread.ManagedThreadId.ToString());
m_form1 = new Form1();
m_form1.FormClosed += new FormClosedEventHandler(m_form1_FormClosed);
m_form1.Show();
}
m_form1.BringToFront();
m_form1.Activate();
}
</code></pre>
<p>So when Form1 takes a while to construct, then it is possible to create 2 because m_form1 is still null when the second call arrives. Locking does not seem to work as it is the same thread both calls (I'm guessing the UI thread) ie the trace writes out *CREATE*1 twice (below).</p>
<pre><code>[3560] *CREATE*1
[3560] *CREATE*1
</code></pre>
<p>Changing the code to include a lock statement does not help me.</p>
<pre><code> private Form1 m_form1;
private object m_Locker = new object();
private void ShowForm1()
{
lock (m_Locker)
{
if (m_form1 == null)
{
Trace.WriteLine("****CREATE****" + Thread.CurrentThread.ManagedThreadId.ToString());
m_form1 = new Form1();
m_form1.FormClosed += new FormClosedEventHandler(m_form1_FormClosed);
m_form1.Show();
}
}
m_form1.BringToFront();
m_form1.Activate();
}
</code></pre>
<p>How should I handle this situation? </p>
<p>Thanks guys</p>
<p>Tim.</p>

<p>I came across this code and wanted others to provide their point of view... is it good or bad ? ;)</p>
<pre><code>Class ReportClass
{
public string ReportName {get; set;}
}
</code></pre>
<p>Then it was used as follows in code:</p>
<pre><code>displayReport(ReportClass.ReportName = cmbReportName.SelectedValue.ToString())
</code></pre>
<p>That is about the simplest form example I can give you.
Quetion is... why can't I find examples ? What would this be called? Is this just asking for trouble?</p>
<p><strong>EDIT:</strong> I'm referring to the inplace assignment. Which I wasn't aware of until today</p>

<p>I have an application where the user selects the dates of a first statement and a last statement. Example, first statement = 1/1/08, last statement = 12/1/08, should equal 12 statements.</p>
<p>However, when using the following code, the result is 11:</p>
<pre><code>numPayments = DateDiff(DateInterval.Month, CDate(.FeeStartDate), CDate(.FeeEndDate))
</code></pre>
<p>Is there another way to calculate this, or do I have to be stuck with adding 1 to the result?</p>

<p>I have two Slackware Linux systems on which the POSIX semaphore <code>sem_open()</code> call fails with errno set to 38. Sample code to reproduce below (the code works fine on CentOS / RedHat).</p>
<p>Are there any kernel or system configuration options that could cause this? Other suggestions?</p>
<p>Systems with issue are Slackware 10.1.0 kernel 2.6.11 /lib/librt-2.3.4.so /lib/libpthread-0.10.so, but the same code works on the much older RedHat 9 kernel 2.4.20 /lib/librt-2.3.2.so /lib/tls/libpthread-0.29.so. (and also works on CentOS 5 kernel 2.6.18 /lib/librt-2.5.so /lib/i686/nosegneg/libpthread-2.5.so).</p>
<p><code>man sem_open</code> suggests this errno means <code>sem_open()</code> is not supported by system.</p>
<pre><code>#define ENOSYS 38 /* Function not implemented */
</code></pre>
<p>The <code>sem_open()</code> userspace is in <code>librt</code> which we link against dynamically and <code>librt</code> is present on the affected systems.</p>
<p>The affected system claims to support POSIX semaphores: <code>_POSIX_SEMAPHORES</code> is true and <code>sysconf(_SC_SEMAPHORES)</code> confirms this.</p>
<p>Thanks,
Kieran</p>
<p>Edit 1: I've added more detail on the software versions in use and removed some irrelevant comments.</p>
<p>Edit 2: /dev/shm is mounted on the good systems and not mounted on the bad systems. Mounting it did not change the behaviour on the affected systems. I think /dev/shm is necessary too but sem_open() is failing before that, and strace supports this.</p>
<pre><code># /* Quick'n'dirty test program to illustrate sem_open failure
#Run this file to auto-build test and run as a.out
# Build
gcc $0 -lrt
if [ $? -ne 0 ] ; then exit ; fi
# Run

#else

#endif

mutex = sem_open(SEM_NAME, O_CREAT, 0666, 1);
if (mutex == SEM_FAILED) printf("Failed %d\n", errno);
else {
puts("Success - pause while you check /dev/shm ");
sleep(5);
sem_close(mutex);
sem_unlink(SEM_NAME);
}
}

<p>I've read a bunch of tutorials involving XNA (and it's various versions) and I still am a little confused on drawing primitives. Everything seems to be really convoluted.</p>
<p>Can someone show me, using code, the simplest XNA implementation of drawing one or two lines on to the screen? Perhaps with a brief explanation (including the boilerplate)?</p>
<p>I'm not a games programmer and I have little XNA experience. My ultimate goal is to draw some lines onto the screen which I will eventually transform with rotations, etc (by hand). However, for this first step.. I need to simply draw the lines! I remember back in my ancient OpenGL days it was fairly straightforward when drawing a line with a few method calls. Should I simply revert to using unmanaged directx calls?</p>

<p>I have these 3 tables + data:</p>
<p><strong>items</strong>: itemId, itemName
<br />data: 1, my item one</p>
<p><strong>categories</strong>: catId, catName
<br />data: 1, my cat one. 2, my cat two</p>
<p><strong>map</strong>: mapId, itemId, catId</p>
<p>When you include item "my item one" in category "my cat one", you insert [1, 1, 1] into the map. When you add "my item one" to "my cat two", you insert [2, 1, 2] into the map. Now let's say we change our mind and only want the item in "my cat two". This means we need to know what categories the item is no longer in and delete the associations from the map. What's the most efficient sequence of steps to take to do so? (I'm looking for a solution that will scale beyond this trivial example.)</p>

<p>I have a bunch of images that need to rotate in and out one at a time every 2 seconds with fancy JQuery fadeIn and fadeOut. I have all the images in the HTML to pre-load them and a setInterval timer that fades the current image out, then fades the next image in. Problem is that sometimes when you are clicking or scrolling during the fade in/out process, the JS gets interrupted and the current image never disappears and the next one fades in giving you two images.</p>
<p>I get the feeling it has something to do with setInterval not running properly every 2 seconds, but are there any better ways to accomplish what I need?</p>
<p>Here's a snippet of code:</p>
<p>HTML</p>
<pre><code><a href="javascript:;">
<img id="img1" src="image1.gif" />
<img id="img2" src="image2.gif" style="display:none;" />
<img id="img3" src="image3.gif" style="display:none;" />
</a>
</code></pre>
<p>JS</p>
<pre><code>var numImages = 3;
var currentImage = 1;
imageInterval = window.setInterval("changeImage();", 2000);
function changeImage()
{
$("#img" + currentImage).fadeOut("slow", function() {
if (currentImage >= numImages)
{
currentImage = 0;
}
$("#img" + (currentImage + 1) ).fadeIn("slow", function() {
currentImage++;
});
});
}
</code></pre>

<p>I have 4 databases with similar schema's, and I'm trying to create a query to return just the table, column pairs that exist ONLY in database 1 and do not exist in database 2, 3, or 4.</p>
<p>Currently I can return the symmetric difference between database 1 and 2 via the following query...</p>
<pre><code>select table_name, column_name from (
select table_name, column_name from [Database1].information_schema.columns
union all
select table_name, column_name from [Database2].information_schema.columns) as tmp
group by table_name, column_name having count(*) = 1
</code></pre>
<p>However, in trying to isolate just those columns in database 1, and doing the same across all 4 databases, things are getting complicated. What is the cleanest solution for this query?</p>

<p>Let's imagine I got this:</p>
<p>index.php generates form with unpredictable number of inputs with certain IDs/Names and different values that can be edited by user and saved by script.php</p>
<pre><code><form action="script.php" method="post">
<input id="1" name="1" type="text" value="1"/>
<input id="24" name="24" type="text" value="2233"/>
<input id="55" name="55" type="text" value="231321"/>
</form>
</code></pre>
<p>Script.php:</p>
<p>Here I need to get something like array of all inputs that were generated by index.php and save every value that corresponds to its id/name.</p>
<p>Is there a way to do this?</p>

<p>I have a class which has a method that is receiving an object as a parameter.
This method is invoked via RMI.</p>
<pre><code>public RMIClass extends Serializable {
public RMIMethod(MyFile file){
// do stuff
}
}
</code></pre>
<p>MyFile has a property called "body", which is a byte array. </p>
<pre><code>public final class MyFile implements Serializable {
private byte[] body = new byte[0];
//....
public byte[] getBody() {
return body;
}
//....
}
</code></pre>
<p>This property holds the gzipped data of a file that was parsed by another application.</p>
<p>I need to decompress this byte array before performing further actions with it. </p>
<p>All the examples I see of decompressing gzipped data assume that I want to write it to the disk and create a physical file, which I do not.</p>
<p>How do I do this?</p>
<p>Thanks in advance.</p>

<p>I'm looking to update our project's jaxb version from 1 to 2. Has anyone tried doing this on their projects and are there any tips that anyone wanting to do this? I understand that each project is unique, I'm just looking for general tips.</p>

<p>We've got a webserver running IIS. We'd like to run maybe a shared blog or something to keep track of information. Because of security issues, we'd like for that part to be only viewable from localhost so people have to remote in to use it.</p>
<p>So, to repeat my question, can part of a website be made viewable from localhost only?</p>

<p>I'm currently optimizing the performance on my company's site; when it was taking 6-10 seconds to download 2MB+ of our homepage and assets (the site is mostly Flash with a lot of media, so it's not 2MB of HTML and viewstate). There are a lot of things that will need to be done to get this download size down; but one thing I definitely want to do is enable HTTP compression to compress our static content, specifically XML, CSS, and JS; I don't imagine compression will do much for the SWFs and JPGs.</p>
<p>I want to enable this on just our staging site so I can do some server testing and benchmarking. This means I'm going to have to do some Metabase editing, since IIS 6 doesn't allow you to set compression on an individual site via IIS manager. The problem with that is the Metabase is locked by IIS so I can't save; and even if I save the edits, I'm required to restart IIS for the changes to take affect; which will take down other live sites hosted on the same server. Is there anyway to enable compression for one site without restarting IIS? I don't mind restarting our staging site; I just don't want this work to take down other sites on the server.</p>
<p>Any assistance is greatly appreciated.</p>

<p>For a windows script I am writing, I need to detect if the machine has Apache 2.2 installed, and to find the application path. </p>
<p>One solution I came up with is to wget <a href="http://localhost:8080/server-info" rel="nofollow noreferrer">http://localhost:8080/server-info</a> and parse the root and the config file from it. This would fail if the server does not use port 8080</p>
<p>Another option would be to call “sc qc Apache2.2” and to parse the returning string. This would fail if the server is not installed as a service, or is using a different name. </p>
<p>Is there any better way to do that?</p>

<p>I want to do something like this:</p>
<pre>
<code>
create table app_users
(
app_user_id smallint(6) not null auto_increment primary key,
api_key char(36) not null default uuid()
);
</code>
</pre>
<p>However this results in a error, is there a way to call a function for a default value in mysql?</p>
<p>thanks.</p>

<p>We frequently have users that create multiple accounts and then end up storing the same lesson activity data more than once. Once they realize the error, then they contact us to merge the accounts into a single one that they can use. </p>
<p>I've been beating myself to death trying to figure out how to write a query in MySQL that will merge their activity logs into a single profile so that I can then delete the other profiles, but I still can't find the query that will work.</p>
<p>The tables look like this:</p>
<pre><code>CREATE TABLE user_rtab (
user_id int PRIMARY KEY,
username varchar,
last_name varchar,
first_name varchar
);
CREATE TABLE lessonstatus_rtab (
lesson_id int,
user_id int,
accessdate timestamp,
score double,
);
</code></pre>
<p>What happens is that a user ends up taking the same lessons and also different lessons under two or more accounts and then they want to take all of their lesson statuses and have them assigned under one user account.</p>
<p>Can anyone provide a query that would accomplish this based on the lastname and firstname fields from the user table to determine all user accounts and then use only the user or username field to migrate all necessary statuses to the one single account?</p>

<p>I have a class that contains two methods like these:</p>
<pre><code>public String getFoo(Int32 a)
{
return getBar(a, "b", null);
}
public String getBar(Int32 a, String b, Int32 c)
{
//do something
return "";
}
</code></pre>
<p>However when I compile my class I get two errors:</p>
<ol>
<li>The best overloaded method match for getBar(int,string,int) has some invalid arguments</li>
<li>Argument '3': cannot convert from '<code><null></code>' to 'int'</li>
</ol>
<p>I think I understand why I'm getting this error: the compiler doesn't know
at the time of compilation what the real type of the object is.
Can someone confirm if I'm correct about the cause of the error or point out the real reason?</p>
<p>More importantly, can I design my code this way? If so, what do I need to do to fix the errors? My reason for designing my class this way is because I don't want to duplicate the code in getBar, in getFoo. The two methods do essentially the same thing except one takes a third parameter.</p>
<p>Thanks.</p>

<p><code>std::auto_ptr</code> is broken in VC++ 8 (which is what we use at work). My main gripe with it is that it allows <code>auto_ptr<T> x = new T();</code>, which of course leads to horrible crashes, while being simple to do by mistake.</p>
<p>From an <a href="https://stackoverflow.com/questions/106508/what-is-a-smart-pointer-and-when-should-i-use-one#110706">answer</a> to another question here on stackoverflow:</p>
<blockquote>
<p>Note that the implementation of std::auto_ptr in Visual Studio 2005 is horribly broken.
<a href="http://connect.microsoft.com/VisualStudio/feedback/ViewFeedback.aspx?FeedbackID=98871" rel="nofollow noreferrer">http://connect.microsoft.com/VisualStudio/feedback/ViewFeedback.aspx?FeedbackID=98871</a>

<p>I want to use </p>
<ul>
<li><code>boost::scoped_ptr</code>, for pointers that shouldn't pass ownership.</li>
<li><code>boost::shared_ptr</code>, for pointers in containers and elsewhere where they are required. </li>
<li><code>std::auto_ptr</code>, for pointers that should/can pass ownership.</li>
</ul>
<p>But since <code>std::auto_ptr</code> is broken for me, I wonder what would be the best approach:</p>
<ul>
<li>Replace <code>std::auto_ptr</code> with something from the net. Like this <a href="http://groups.google.com/group/comp.std.c++/msg/97a2539a1bbbe491" rel="nofollow noreferrer">this</a> one from Rani Sharoni (haven't tried it yet).</li>
<li>Use <code>boost::shared_ptr</code> instead. Will of course work, although there will be some minor overhead that I don't care about. But I want to use <code>auto_ptr</code> to signal the intent of the pointer. (See <a href="https://stackoverflow.com/questions/197048/idiomatic-use-of-stdautoptr-or-only-use-sharedptr#197083">this</a> answer for a vote on this approach.)</li>
<li>I will never need to pass ownership in practice, so I shouldn't worry about this.</li>
</ul>
<hr>
<p>Update:
Here is what I did:
I copied the aforementioned auto_ptr implementation by Rani Sharoni. <a href="http://groups.google.com/group/comp.std.c++/msg/97a2539a1bbbe491" rel="nofollow noreferrer">From here</a>.</p>
<p>Did some minor tests:</p>
<pre><code>class T
{
public:
T() {
OutputDebugStringA("T\n");
};
~T() {
OutputDebugStringA("~T\n");
};
};
{
fix::auto_ptr<T> x(new T); // This just works.
}
{
fix::auto_ptr<T> x = (new T); // Doesn't compile. Great!
}
{
fix::auto_ptr<T> x = fix::auto_ptr<T>(new T); // Transfer of ownership works also.
}
</code></pre>
<p>Of course these tests are by no means exhaustive and you shouldn't trust them. Implementing an exception safe templated class is hairy business. At least this works better than the built in one.</p>
<p><strike>Note: I don't know if I'm allowed to use this implementation yet, with respect to copyright. I have emailed Rani and I'm waiting for a reply. I'll update this post when I know more.</strike>
Permission is granted for everyone to use Rani Sharoni's auto_ptr implementation as you wish.</p>
<p>Thank you for all your replies.</p>

<p>I have been experimenting with Lambda expressions in Oxygene. Very simple recursive lambda expression to calculate a fibonacci number :</p>
<pre><code>var fib : Func<int32, int32>;
fib := n -> iif(n > 1, fib(n - 1) + fib(n - 2), n);
fib(3);
</code></pre>
<p>When I run this code I get a nullreferenceexception. Any ideas as to what I'm doing wrong?</p>

<p>A colleague recently asked me how to deep-clone a Map and I realized that I probably have never used the clone() method- which worries me.</p>
<p>What are the most common scenarios you have found where you need to clone an object?</p>

<p>This probably sounds really stupid but I have noo idea how to implement jquery's rounded corners (<a href="http://www.methvin.com/jquery/jq-corner-demo.html" rel="nofollow noreferrer">http://www.methvin.com/jquery/jq-corner-demo.html</a>). My javascript-fu is complete fail and I can't seem to get it to work on my page. Can anyone show me a simple example of the HTML and JavaScript you would use to get them to show? Apologies for my idiocy.</p>

<p>I'm using MessageFormat to format some addresses with a template like this:</p>
<pre><code>"{0}\n{1}\n{2}\n{3}, {4} {5}"
</code></pre>
<p>where</p>
<ul>
<li>0 = street 1</li>
<li>1 = street 2</li>
<li>2 = street 3</li>
<li>3 = city</li>
<li>4 = state</li>
<li>5 = zip</li>
</ul>
<p>Most of these fields are optional when captured. How do I avoid having an empty line when for instance, there is not street 3? I could use a template like this "{0}{1}{2}{3}{4}{5}" and then substitute either "street 3\n" or "" accordingly, but then the template doesn't provide much benefit toward formatting.</p>
<p>Is there a way to include conditionals in the format string? Or is there another, preferably lightweight, templating tool available that supports conditional formatting?</p>

<p>Is it better in C++ to pass by value or pass by reference-to-const?</p>
<p>I am wondering which is better practice. I realize that pass by reference-to-const should provide for better performance in the program because you are not making a copy of the variable.</p>

<p>In Reporting Services I would like to add a parameter that contains data from a custom code block. Ideally, I would be able to run the following code (this is a simple testing example):</p>
<pre><code>Function GetPeriods() As String()
Dim values As System.Collections.ArrayList =
New System.Collections.ArrayList()
For i as integer = 1 to 24
values.Add(i)
Next
Return values.ToArray()
End Function
</code></pre>
<p>and put the following in the "Text Field" of the parameter:</p>
<pre><code>=Code.GetPeriods()
</code></pre>
<p>However, when I run the report, the parameter I apply this to is disabled and empty. Is there a different technique that should be used? Or am I doing something wrong?</p>

<p>Is there a way to download older versions of Visual C++ Express? I'm particularly interested in Visual C++ 2005 Express (PRIOR SP1) and Visual C++ Toolkit 2003. I tried googling for them, but all the sites linked to microsoft.com, from where microsoft (for some reason) has taken them down.</p>
