<p>I'm getting something pretty strange going on when trying to read some data using the MySql .net connector. Here's the code:</p>
<pre><code>IDataReader reader = null;
using (MySqlConnection connection = new MySqlConnection(this.ConnectionString))
{
String getSearch = "select * from organization";
MySqlCommand cmd = new MySqlCommand(getSearch, connection);
cmd.CommandType = CommandType.Text;
connection.Open();
reader = cmd.ExecuteReader();
while (reader.Read())
{
// response write some stuff to the screen (snipped for brevity)
}
}
</code></pre>
<p>If I put a breakpoint after the ExecuteReader and expand the results view in Visual Studio (hovering over reader and expanding), I can see the rows returned by the query. If I then let that close and expand the results view again, I get the message 'Enumeration yielded no results'.</p>
<p>It seems as if the contents of the reader are getting reset as soon as they're viewed.</p>
<p>As for what we've tried:<br>
- the SQL runs fine directly on to DB<br>
- Binding the results of the query directly to a datagrid just returns an empty datagrid<br>
- got the latest version of the .net connector<br>
- tried on two different machines to rule out any local errors</p>
<p>So far nothing's worked.</p>
<p>If anyone could offer any ideas or suggestions they would be very much appreciated.</p>

<p>Thanks for going to answer my question. I have the folowing pages.</p>
<ul>
<li>login.aspx</li>
<li>default.aspx</li>
<li>xxx.aspx</li>
</ul>
<p>After logging into application default.aspx will be displayed. Now if the user is trying to open <a href="http://server/" rel="nofollow noreferrer">http://server/</a><strong>xxx.aspx</strong>?Id=1234 by specifying its URL directly in a browser, the login screen is displayed and after successfull login, system redirects to "default.aspx" and not to "<a href="http://server/" rel="nofollow noreferrer">http://server/</a><strong>xxx.aspx</strong>?Id=1234". Actually there is an external application that would call my system like that. So Please let me know why is this happening. The .Net login control is used to login into the application. Kindly help me to solve this issue.</p>
<p>Thanks,<br>
Ang Vin</p>

<p>It seems that the following piece of HTML is ignored in IE7 but works ok in IE6/FF. It supposes to override all the html links to be opened in the desired frame</p>
<pre><code><HEAD>
<title>LeftPane</title>
<base target="rightFrame">
</HEAD>
</code></pre>
<p>The above code is the header of a left frame that holds an Infragistics UltraWebTree (tree menu) which doesn't support the TargetFrame property.</p>
<p>Is there another way to add the target attribute to all the links elements on the desired page. </p>
<p>Any server or client-side code workarounds?</p>
<p>The site is built on ASP.Net 1.1 and Infragistics V 2.0</p>
<p><strong>Update</strong>
the web page is aspx an the doctype is </p>
<pre><code><!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" >
</code></pre>

<p>If I have a table like this:</p>
<pre><code>CREATE TABLE sizes (
name ENUM('small', 'medium', 'large')
);
</code></pre>
<p>Is MySQL going to store those strings in every row, or internally will it use something smaller like integers to know which enum value to refer to?</p>
<p>I want to use an enum in a table but I'm worried if it's as wasteful as storing a string in every row.</p>

<p>I'm an old hand at embedded programming but new to CE and having a lot of trouble doing reasonably simple things, because I am not familiar with the API and struggling to understand the obscure MSDN docs.</p>
<p>All I want to do is minimize and maximise two separate applications that are running from one of the applications.</p>
<p>E.g. Application A decides that now it is time for it to appear and then minimises application B (App B being a third party application e.g. Notepad, no access to source code etc) and then at a later stage maximising B and minimising itself.</p>
<p>Application A would be written by myself.</p>
<p>I'm sure this must be very simple, but where to find answers.. :)</p>
<p>Thanks in advance.
EOI</p>

<p>I am writing a java program that needs a file open dialog. The file open dialog isn't difficult, I'm hoping to use a <code>JFileChooser</code>. My problem is that I would like to have a dual pane <code>JFrame</code> (consisting of 2 <code>JPanels</code>). The left panel would have a <code>JList</code>, and the right panel would have a file open dialog. </p>
<p>When I use <code>JFileChooser.showOpenDialog()</code> this opens the dialog box above all other windows, which isn't what I want. Is there any way to have the <code>JFileChooser</code> (or maybe another file selection dialog) display inside a <code>JPanel</code> and not pop-up above it?</p>
<p>Here is the code that I've tried, at this point it's very simplified. I'm only trying to get the <code>JFileChooser</code> to be embedded in the <code>JPanel</code> at this point.</p>
<pre><code>public class JFC extends JFrame{
public JFC()
{
setSize(800,600);
JPanel panel= new JPanel();
JFileChooser chooser = new JFileChooser();
panel.add(chooser);
setVisible(true);
chooser.showOpenDialog(null);
}
public static void main(String[] args)
{
JFC blah = new JFC();
}
}
</code></pre>
<p>I have also tried calling <code>chooser.showOpenDialog</code> with <code>this</code> and <code>panel</code>, but to no avail. Also, I have tried adding the <code>JFileChooser</code> directly to the frame. Both of the attempts listed above still have the <code>JFileChooser</code> pop up in front of the frame or panel (depending on which I add the <code>JFileChooser</code> to).</p>

<p>I've read quite a bit of the Red Bean Software SVN Book, and some of the questions here on SO, but I want to make sure I'm going about this in the right way the first time around step-by-step before I begin using it. Is this correct?</p>
<ol>
<li>Install SVN.</li>
<li><p>Create SVN repository at /usr/local/svn. Directory structure looks like this:</p>
<pre><code>-- conf
-- db
-- format
-- hooks
-- locks
-- README.txt
</code></pre></li>
<li><p>Create folders through command line for repository organization (including projects and vendors).</p>
<pre><code>-- conf
-- db
-- format
-- hooks
-- locks
-- projects
-- project_name
-- vendor
-- trunk
-- branches
-- tags
-- project_name
-- vendor
-- trunk
-- branches
-- tags
-- README.txt
</code></pre></li>
<li><p>Checkout vendor code into vendor folder under the correct project name.</p></li>
<li>Export vendor code into trunk under the correct project name (no merge necessary, as I have no project trunk files yet).</li>
<li>Create users/permissions in /svnroot/conf/passwd and /svnroot/conf/svnserve.conf.</li>
<li>Make sure that svnserve is running, and on my local SVN client (TortoiseSVN), checkout the trunk for the project that I need.</li>
</ol>
<p>I don't need to serve this up by public URL, so I'm not configuring for Apache. The server is not in our network, but is a dedicated CentOS box we rent. Thanks for any thoughts and advice.</p>
<p><strong>EDIT:</strong></p>
<p>I guess I'm confused because I don't have code or a project to begin with, so I am starting fresh from the vendor's code. Do I need to create a directory structure somewhere on the server that includes my project_name w/ vendor, trunk, branches and tags subfolders, import that into my repo, and then import the code from the vendor into the vendor folder? The idea is that I can get updates from the vendor, and then merge those updates with any changes I made to my trunk.</p>

<p>I'm considering migrating a project to managed code, but I've heard that the .NET runtime is huge--several times larger than my executable binary, in fact. That just seems like the tail wagging the dog to me. But I've also been told that some CLR implementations, such as Mono, are modular, and you can create a custom distribution for them that only contains the parts you actually need.</p>
<p>Problem is, I'm having a surprisingly difficult time finding answers on Google to what ought to be very simple questions about this. How big are the full CLR packages on various implementations, which ones support this modular distribution ability, and how big would the runtime end up being for a standard windows-style (form-based) app that doesn't use tons of .NET bells and whistles? (Mostly what I'm interested in is the Assembly system's inherent ability to create plugins easily, and the ability to build scripting into my program through JIT compilation.)</p>
<p>EDIT: I'm not interested in installer sizes or download times. I want to know the size of the actual framework, uncompressed and ready to run, as it will be on the end-users' systems.</p>

<p>ok so basically I am asking the question of their name
I want this to be one input rather than Forename and Surname.</p>
<p>Now is there any way of splitting this name? and taking just the last word from the "Sentence" e.g.</p>
<pre><code>name = "Thomas Winter"
print name.split()
</code></pre>
<p>and what would be output is just "Winter"</p>

<p>I'm running through an XML document, selecting all the elements, and creating links based on the ancestor which is usually two nodes up in the tree, but occasionally 3 or 4 nodes up. For the majority of the elements, using <code><xsl:value-of select="translate(../../@name,$uc,$lc)" /></code> works just fine, but for the cases where the ancestor is 3 or so nodes up, I'd like to use <code><xsl:value-of select="translate(ancestor::package/@name,$uc,$lc)" /></code>, but this doesn't work.</p>
<p>I'm using xsltproc from Ruby to do my XSL transforms.</p>
<p>Sample tree (yes, it has XSLT in it, no, I'm not trying to process it):</p>
<pre><code><package name="blork!" xmlns="http://xml.snapin.com/XBL">
<xsl:template name="doSomething">
<tokens>
<token name="text-from-resource" export="public" />
</tokens>
</xsl:template>
</package>
</code></pre>
<p>The XSL I'm using:</p>
<pre><code><xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:s4="http://xml.snapin.com/XBL">
<xsl:template match="/">
<xsl:if test="count(//s4:token) >0">
<xsl:text>Tokens!</xsl:text>
<xsl:for-each select="//s4:token">
<xsl:choose>
<xsl:when test="@export='global'" />
<xsl:otherwise>
<xsl:value-of select="translate(ancestor::s4:package/@name,$uc,$lc)" />
</xsl:otherwise>
</xsl:choose>
</xsl:for-each>
</xsl:if>
</xsl:template>
</xsl:stylesheet>
</code></pre>
<p><em>Edit:</em> Ah, right, forgot the namespace on the select. The parser's finding that ancestor properly for most cases, but it still can't find it when there's an xsl: node in there, and the target file has no namespace for xsl. I'd prefer not to modify the target file, because it's production code---I'm just writing an autodoc tool.</p>

<p><strong>What is the best way to share Delphi source files among projects?</strong></p>
<p><em>Clarification: We want to use a single source file in multiple Delphi projects. We've been using our SCM tool to put the same file into multiple folders, but this is not a super-elegant experience and we are also considering migrating to a tool that doesn't support this.</em></p>
<p>As I’ve been investigating this question, I’ve considered a few different approaches, but I’d like to know what you’re doing and how you find your approach.</p>
<p><strong>Important Scenarios:</strong></p>
<ul>
<li>Code-time
<ul>
<li>Adding a new sharing dependency should require explicit declaration, so that sharing is managed.</li>
<li>Adding a new sharing dependency should still be relatively simple; it should not require a complicated process.
<ul>
<li>One file which lists all of the project’s “imported” files (from externally) would be nice.</li>
</ul></li>
</ul></li>
<li>Compile-time
<ul>
<li>All projects should always build with the one current version (current as of the source sync state plus local edits).
<ul>
<li>(Maintaining different versions in different locations should use file branching, which is not the topic, here.)</li>
</ul></li>
<li>Whether each project should be able to affect the shared file’s compilation with different compiler settings (including flags) is arguable.
<ul>
<li>It’s arguably easier to maintain (i.e. long-term) source code that is always built consistently.</li>
<li>It’s arguably easier to make maintenance fixes (i.e. short-term) if the scope of said changes can easily be restricted to one project.</li>
</ul></li>
</ul></li>
<li>Debug-time
<ul>
<li>The correct version of the source should automatically open, when stepping into a routine or setting a breakpoint.</li>
<li>Editing the displayed source should affect the next build.
<ul>
<li>We do not want to debug against a temporary copy of the source: we'd probably lose code, in the confusion.</li>
</ul></li>
</ul></li>
</ul>
<p><strong>Considerations:</strong></p>
<ul>
<li>Near-Term:
<ul>
<li>What approach will be simplest to put in place?</li>
</ul></li>
<li>Long-Term:
<ul>
<li>What approach will be simplest to use and maintain?</li>
</ul></li>
</ul>
<p>Thanks, in advance, for your feedback!</p>
<p>Mattias</p>
<p><hr/>
<strong>--- UPDATE ---</strong></p>
<p>Thanks for your feedback, via answers, comments, and votes!</p>
<p>I've started down the path of putting shared files into one "producer" project and importing a list of compiled files into each "consumer" project. The projects are being linked together with MSBuild. Once things are more nailed-down, I'll edit this question and the "Library Project" answer, to share what I've learned.</p>
<p>Stay tuned! (But don't hold your breath; you'll asphyxiate within minutes! :P )</p>

<ol>
<li><p>In a simple winform application, I call a function that endlessy create files on a button click event. I add Application.DoEvents() to the loop.</p></li>
<li><p>I press the red X to close the form.</p></li>
<li><p>the form closes, but files continue to be created ... </p></li>
</ol>
<p>I think its on the buttons thread, but shouldnt it be a background one ? trying changing Thread.CurrentThread.IsBackGround to True on the loop function does not help.</p>
<p>Ideas ?</p>

<p>I the following styles:</p>
<pre><code>a.button {
background-color: orange;
margin: .2cm;
padding: .2cm;
color: black;
font-family: sans-serif;
text-decoration: none;
font-weight: bold;
border: solid #000000;
}
a.buttonMouseover {
background-color: darkGoldenRod;
margin: .2cm;
padding: .2cm;
color: black;
font-family: sans-serif;
text-decoration: none;
font-weight: bold;
border: solid #000000;
}
</code></pre>
<p>And the following javascript code (my first ever btw):</p>
<pre><code>function backgroundChangeIn(element){
if (element.className = "a.button"){element.className = "buttonMouseover";}
}
function backgroundChangeOut(element){
if (element.className = "a.buttonMouseover"){element.className = "button";}
}
</code></pre>
<p>And, the following element that should change the background on mouseover:</p>
<pre><code><a class="button" href="" onmouseover="backgroundChangeIn(this)" onmouseout="backgroundChangeOut(this)">A Button</a>
</code></pre>
<p>It is working for me so far. But I was wondering if there was a better way.</p>
<p>(Sorry about all the code)</p>

<p>I'm building an XML document with PHP's SimpleXML extension, and I'm adding a token to the file:</p>
<pre><code>$doc->addChild('myToken');
</code></pre>
<p>This generates (what I know as) a self-closing or single tag:</p>
<pre><code><myToken/>
</code></pre>
<p>However, the aging web-service I'm communicating with is tripping all over self-closing tags, so I need to have a separate opening and closing tag:</p>
<pre><code><myToken></myToken>
</code></pre>
<p>The question is, how do I do this, outside of running the generated XML through a <strong>preg_replace</strong>?</p>

<p>I am using XmlSerializer to write and read an object to xml in C#. I currently use the attributes <code>XmlElement</code> and <code>XmlIgnore</code> to manipulate the serialization of the object.</p>
<p>If my xml file is missing an xml element that I require, my object still deserializes (xml -> object) just fine. How do I indicate (preferably via Attributes) that a certain field is "required"?</p>
<p>Here is a sample method of what I am using currently:</p>
<pre><code>[XmlElement(ElementName="numberOfWidgets")]
public int NumberThatIsRequired {
set ...;
get ...;
}
</code></pre>
<p>My ideal solution would be to add something like an <code>XmlRequired</code> attribute. </p>
<p>Also, is there a good reference for what Attributes are available to manipulate the behavior of XmlSerializer?</p>

<p>I've got a (SQL Server 2005) database where I'd like to create views on-the-fly. In my code, I'm building a CREATE VIEW statement, but the only way I can get it to work is by building the entire query string and running it bare. I'd like to use parameters, but this:</p>
<pre><code>SqlCommand cmd = new SqlCommand("CREATE VIEW @name AS SELECT @body");
cmd.Parameters.AddWithValue("@name", "foo");
cmd.Parameters.AddWithValue("@body", "* from bar");
</code></pre>
<p>tells me there's an error "near the keyword VIEW" (presumably the "@name") -- needless to say <code>"CREATE VIEW foo AS SELECT * FROM bar"</code> works like a champ.</p>
<p>Is this just not possible? If not, is there a better way to clean up the input before running the CREATE statement? In some cases, the query body could have user input and I'd just feel safer if there was some way that I could say "treat this as the body of a single select statement". Maybe what I'm asking for is just too weird?</p>
<p><hr/>
FOLLOWUP 04 Nov:
OK, yes, what I want is sort of like SQL injection when you get down to it, but I would like to at least minimize (if not totally remove) the option of running this command and dropping a table or something. Granted, the user this is running as doesn't have permissions to drop any tables in the first place, but I think you get the idea. I'd love to have a way of saying, in effect, <code>"This statement will not alter any existing data in any way{ ... }"</code>.</p>
<p>The way it's coded right now is to do string concatenation like in <strong>friol</strong>'s answer, but that does no sanitization at all. I'd feel better if I could at least scrub it for suspect characters, like ; or -- or what have you. I was hoping there might be a library function to do the scrub for me, or something along those lines.</p>

<p>What exception should I throw if I encounter an illegal state - for instance, an initialization method that should only be called once being called a second time? I don't really see any built-in exception that makes sense. This seems like something that should be in the framework - am I not poking in the right spot?</p>

<p>Let's say I have a simple stored procedure that looks like this (note: this is just an example, not a practical procedure):</p>
<pre><code>CREATE PROCEDURE incrementCounter AS
DECLARE @current int
SET @current = (select CounterColumn from MyTable) + 1
UPDATE
MyTable
SET
CounterColumn = current
GO
</code></pre>
<p>We're assuming I have a table called 'myTable' that contains one row, with the 'CounterColumn' containing our current count.</p>
<p>Can this stored procedure be executed multiple times, at the same time? </p>
<p>i.e. is this possible:</p>
<p>I call 'incrementCounter' twice. Call A gets to the point where it sets the 'current' variable (let's say it is 5). Call B gets to the point where it sets the 'current' variable (which would also be 5). Call A finishes executing, then Call B finishes. In the end, the table should contain the value of 6, but instead contains 5 due to the overlap of execution</p>

<p>I want to create a view that consists solely of a <code>UITextView</code>. When the view is first shown, by default, I'd like the keyboard to be visible and ready for text entry. This way, the user does not have to touch the <code>UITextView</code> first in order to begin editing.</p>
<p>Is this possible? I see the class has a notification called <code>UITextViewTextDidBeginEditingNotification</code> but I'm not sure how to send that, or if that is even the right approach. </p>

<p>What is the best way to convert an array of bytes declared as TBytes to a unicode string in Delphi 2009? In my particular case, the TBytes array has UTF-16 encoded data already (2 bytes for each char).</p>
<p>Since TBytes doesn't store a null terminator, the following will only work if the array happens to have #0 in the memory adjacent to it. </p>
<pre><code>MyString := string( myBytes );
</code></pre>
<p>If not, the string result will have random data at the end (it could also probably cause a read violation depending on how long it took to encounter a #0 in memory).</p>
<p>If I use the ToBytes function, it returns 't'#0'e'#0's'#0't'#0, which is not what I want.</p>

<p>The company I work for writes a lot smallish Perl and Bash scripts to massage data into something usable for our software. These scripts, like any code, can change. I provided them CVS because of the file versioning rather than repository versioning. Anyway, I am thinking out a deploy tool to get the scripts from development to production. The production server will have it's own simple versioning system in that if one of the scripts' md5 sum does not match the one in a database it will not run the script and email the appropriate parties. </p>
<p>I want to force the programmers to deploy the most current CVS version of the script. If it is not the most current it should die with a message telling them they have to check in their version first. I realize there might be cases where you need to deploy an old file. Those would be exceptions and could be handled as such.</p>
<p>What's the best to do this? Is it just as simple as doing a 'cvs diff' ? </p>

<p>I am performing two validations on the client side on the samve event.
I have defined my validations as shown below</p>
<pre><code>btnSearch.Attributes["OnClick"] = "javascript:return prepareSave(); return prepareSearch();"
</code></pre>
<p>Pseudo code for </p>
<pre><code>prepareSave():
{
if (bPendingchanges)
{
return confirm('Need to save pending changes first, click OK and loose changes or cancel to save them first')
}
else
{return true}
}
</code></pre>
<p>Pseudo code for </p>
<pre><code>prepareSearch():
{
if (bNoSearchText)
{
alert('Please specify search criteria before proceeding')
return false;
}
else
{return true;}
}
</code></pre>
<p>When <code>bPendingchanges=false</code>, I never get the second validation running.
Anyone who can quickly spot what I have overlooked here? Please?</p>

<p>As Scott Myers wrote, you can take advantage of a relaxation in C++'s type-system to declare clone() to return a pointer to the actual type being declared:</p>
<pre><code>class Base
{
virtual Base* clone() const = 0;
};
class Derived : public Base
{
virtual Derived* clone() const
};
</code></pre>
<p>The compiler detects that clone() returns an pointer to the type of the object, and allows Derived to override it to return a pointer to derived.</p>
<p>It would desirable to have clone() return a smart pointer that implies transfer of ownership semantics, like the following:</p>
<pre><code>class Base
{
virtual std::auto_ptr<Base> clone() const = 0;
};
class Derived : public Base
{
virtual std::auto_ptr<Derived> clone() const;
};
</code></pre>
<p>Unfortunately, the relaxation of the conventions does not apply to templated smart pointers, and the compiler will not allow the override.</p>
<p>So, it seems I am left with two options:</p>
<ol>
<li>Have clone() return a "dumb" pointer, and document that clients are responsible for disposing of it.</li>
<li>Have clone() return a smart base pointer, and have clients use dynamic_cast to save them to a Derived pointer if they need it.</li>
</ol>
<p>Is one of these approaches preferred? Or is there a way for me to eat my transfer of ownership semantics and have my strong type safety too?</p>

<p>I'd like to strip out occurrences of a specific tag, leaving the inner XML intact. I'd like to do this with one pass (rather than searching, replacing, and starting from scratch again). For instance, from the source:</p>
<pre><code><element>
<RemovalTarget Attribute="Something">
Content Here
</RemovalTarget>
</element>
<element>
More Here
</element>
</code></pre>
<p>I'd like the result to be:</p>
<pre><code><element>
Content Here
</element>
<element>
More Here
</element>
</code></pre>
<p>I've tried something like this (forgive me, I'm new to Linq):</p>
<pre><code>var elements = from element in doc.Descendants()
where element.Name.LocalName == "RemovalTarget"
select element;
foreach (var element in elements) {
element.AddAfterSelf(element.Value);
element.Remove();
}
</code></pre>
<p>but on the second time through the loop I get a null reference, presumably because the collection is invalidated by changing it. What is an efficient way to make remove these tags on a potentially large document?</p>

<p>I have a very standard <code>Gridview</code>, with Edit and Delete buttons auto-generated.
It is bound to a <code>tableadapter</code> which is linked to my <code>RelationshipTypes</code> table.</p>
<pre><code>dbo.RelationshipTypes:
ID, Name, OriginConfigTypeID, DestinationConfigTypeID
</code></pre>
<p>I wish to use a label that will pull the name from the <code>ConfigTypes</code> table, using the <code>OriginConfigTypeID</code> and <code>DestinationTypeID</code> as the link.</p>
<pre><code>dbo.ConfigTypes:
ID, Name
</code></pre>
<p>My problem is, I can't automatically generate Edit and Delete buttons using an <code>Inner Join</code> in my dataset. Or can I?</p>
<p>Here is my code:</p>
<pre><code><asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False"
AutoGenerateDeleteButton="True" AutoGenerateEditButton="True" CssClass="TableList"
DataKeyNames="ID" DataSourceID="dsRelationShipTypes1">
<Columns>
<asp:BoundField DataField="ID" HeaderText="ID" InsertVisible="False" ReadOnly="True"
SortExpression="ID" Visible=False/>
<asp:TemplateField HeaderText="Origin" SortExpression="OriginCIType_ID">
<EditItemTemplate>
&nbsp;<asp:DropDownList Enabled=true ID="DropDownList2" runat="server" DataSourceID="dsCIType1"
DataTextField="Name" DataValueField="ID" SelectedValue='<%# Bind("OriginCIType_ID") %>'>
</asp:DropDownList>
</EditItemTemplate>
<ItemTemplate>
&nbsp;
<asp:Label ID="Label2" runat="server" Text='<%# Bind("OriginCIType_ID") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Name" SortExpression="Name">
<EditItemTemplate>
<asp:TextBox ID="TextBox3" runat="server" Text='<%# Bind("Name") %>'></asp:TextBox>
</EditItemTemplate>
<ItemTemplate>
<asp:Label ID="Label3" runat="server" Text='<%# Bind("Name") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Destination" SortExpression="DestinationCIType_ID">
<EditItemTemplate>
<asp:DropDownList ID="DropDownList3" runat="server" DataSourceID="dsCIType1" DataTextField="Name"
DataValueField="ID" SelectedValue='<%# Bind("DestinationCIType_ID") %>'>
</asp:DropDownList>
</EditItemTemplate>
<ItemTemplate>
<asp:Label ID="Label1" runat="server" Text='<%# Bind("DestinationCIType_ID") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
</code></pre>
<p>So I did try to create my own edit and delete buttons, but kept receiving the error </p>
<blockquote>
<p>"cannot find update method"</p>
</blockquote>
<p>or something similar. Do I have to manually code the delete and update methods in my code-behind?</p>

<p>I want to assign a resource I already have a second name, similar to using the BasedOn property of Styles. Specifically I have a brush that I use for a group of elements called ForegroundColor and I would like to use it in a control template (a ComboBox) calling it MouseOverBackgroundBrush. I would like to do something like this:</p>
<pre><code><ResourceCopy x:key="MouseOverBackgroundBrush" Value="{StaticResource ForegroundColor}" />
</code></pre>
<p>Is there a way to do this or is there a better way to go about this in Xaml?</p>

<p>In writing the code that throws the exception I asked about <a href="https://stackoverflow.com/questions/259800/is-there-a-built-in-net-exception-that-indicates-an-illegal-object-state">here</a>, I came to the end of my message, and paused at the punctuation. I realized that nearly every exception message I've ever thrown probably has a ! somewhere.</p>
<pre><code>throw new InvalidOperationException("I'm not configured correctly!");
throw new ArgumentNullException("You passed a null!");
throw new StupidUserException("You can't divide by 0! What the hell were you THINKING??? DUMMY!!!!!");
</code></pre>
<p>What tone do you take when writing exception messages? When going through logs, do you find any certain style of message actually helps more than another?</p>

<p>I would like to know how to do the same thing for JLabel . I'm sure there has to be a better way than to create as many labels as there are characters in the string . Right ?</p>
<p><strong>EDIT:</strong> how can I insert an image into my post ? The button for the image shows the image in the preview section , but when I actually post the data , I only get some text back , like the tags are getting messed up .</p>

<p>Can you explain or provide a link to an explanation of how Excel VBA code password protection actually works in versions prior to 2007? What is the difference in Excel 2007 and previous versions in terms of password protection?</p>
<p>Also does Excel's password protection actually encrypt the code? How does Excel execute the code if it is encrypted?</p>
<p>Lastly, how does password removal software for excel work?</p>

<p>Check it out: this little .NET Console Program yields interesting results...notice how I'm converting a float to an integer in two different ways:</p>
<pre><code>using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace CastVsConvert
{
class Program
{
static void Main(string[] args)
{
int newWidth = 0;
CalculateResizeSizes(600, 500, out newWidth);
}
static void CalculateResizeSizes(int originalWidth, int maxWidth, out int newWidth)
{
float percentage = 1.0F;
percentage = maxWidth / (float)originalWidth;
newWidth = (int)((float)originalWidth * percentage);
int newWidthConvert = Convert.ToInt32((float)originalWidth * percentage);
Console.Write("Percentage: {0}\n", percentage.ToString());
Console.Write("Cast: {0}\n", newWidth.ToString());
Console.Write("Convert: {0}\n", newWidthConvert.ToString());
}
}
}
</code></pre>
<p>I would expect the output for "Cast" and "Convert" to be the same, but they're not...here's the output:</p>
<pre><code>C:\Documents and Settings\Scott\My Documents\Visual Studio 2008\Projects\CastVsC
onvert\CastVsConvert\bin\Debug>CastVsConvert.exe
Percentage: 0.8333333
Cast: 499
Convert: 500
</code></pre>
<p>Does anybody know why .NET is returning different values here? </p>

<p>I have the following solution project structure:</p>
<blockquote>
<p>Application.Core.Entities</p>
<p>Application.Xtend.CustomerName.Entities</p>
</blockquote>
<p>In the Core project I have an entity <strong>Customer</strong> defiend. In the XTend project, I have an entity defined that subclasses Customer named <strong>xCustomer</strong> (for lack of a better name at this time...).</p>
<p>The idea here is that we have a Core domain model in our application. A customer can then create a new assembly that contains extensions to our core model. When the extension assembly is present a smart <a href="http://martinfowler.com/eaaCatalog/repository.html" rel="noreferrer">IRepository</a> class will return a subclass of the core class instead.</p>
<p>I am attempting to map this relationship in <a href="http://nhforge.org/" rel="noreferrer">NHibernate</a>. Using <a href="http://code.google.com/p/fluent-nhibernate/" rel="noreferrer">Fluent NHibernate</a> I was able to generate this mapping:</p>
<pre><code><?xml version="1.0" encoding="utf-8"?>
<hibernate-mapping xmlns="urn:nhibernate-mapping-2.2"
default-lazy="false"
assembly="NHibernate.Core.Entites"
namespace="NHibernate.Entites"
default-access="field.camelcase-underscore">
<!-- Customer is located in assembly Application.Core.Entities -->
<class name="Customer" table="Customers" xmlns="urn:nhibernate-mapping-2.2">
<id name="Id" column="Id" type="Int64">
<generator class="native" />
</id>
<component name="Name" insert="true" update="true">
<property name="LastName" column="LastName" length="255" type="String" not-null="true">
<column name="LastName" />
</property>
<property name="FirstName" column="FirstName" length="255" type="String" not-null="true">
<column name="FirstName" />
</property>
</component>
<!-- xCustomer is located in assembly Application.XTend.CustomerName.Entities -->
<joined-subclass name="xCustomer" table="xCustomer">
<key column="CustomerId" />
<property name="CustomerType" column="CustomerType" length="255" type="String" not-null="true">
<column name="CustomerType" />
</property>
</joined-subclass>
</class>
</hibernate-mapping>
</code></pre>
<p>But NHib throws the following error:</p>
<blockquote>
<p>NHibernate.MappingException:
persistent class
Application.Entites.xCustomer,
Application.Core.Entites not found
---> System.TypeLoadException: Could not load type
'Application.Entites.xCustomer' from
assembly 'Application.Core.Entites,
Version=1.0.0.0, Culture=neutral,
PublicKeyToken=null'..</p>
</blockquote>
<p>Which makes sense xCustomer is not defined in the Core library.</p>
<p>Is it possible to span different assemblies like this? Am I approaching the problem wrong?</p>

<p>Wondering if my approach is ok or could be improved:</p>
<pre><code>Public Class Company
private _id as Integer
private _name as String
private _location as String
Public Function LoadMultipleByLocation(Byval searchStr as String) as List(Of Company)
'sql etc here to build the list
End Function
End Classs
</code></pre>
<p>Thoughts on having the object mapping like this?</p>

<p>I have to simultaneously load data into a table and run queries on it. Because of data nature, I can trade integrity for performance. How can I minimize the overhead of transactions?</p>
<p>Unfortunately, alternatives like MySQL cannot be used (due to non-technical reasons). </p>

<p>I would like to load the numbers into a matrix, and the column titles into a variable that would be equivalent to:</p>
<pre><code>variable_names = char('var1', 'var2', 'variable3');
</code></pre>
<p>I don't mind to split the names and the numbers in two files, however preparing matlab code files and eval'ing them is not an option. </p>

<p>I am trying to create an instance of a COM object. I have the class name that implements the interface and I get a CLSID by using CLSIDFromProgID(). So since I am getting a CLSID I thought everything should be fine from now on. However when I do a call to CreateInstance and pass in the CLSID, I get an error saying "Class not registered". Also I get this error only in some computers. It runs error free on several computers. I don't understand where the problem could be. Is my registry dirty? Does anyone know what is going on here? Thanks for your help!</p>
<p>I just want to add that this is a .NET COM class. The appropriate entries are in the registry and the DLL is in the GAC.</p>

<p>If I have a query to return all matching entries in a DB that have "news" in the searchable column (i.e. <code>SELECT * FROM table WHERE column LIKE %news%</code>), and one particular row has an entry starting with "In recent World news, Somalia was invaded by ...", can I return a specific "chunk" of an SQL entry? Kind of like a teaser, if you will.</p>

<p>I want to make a transparent dialog. I capture the OnCtlColor message in a CDialog derived class...this is the code:</p>
<pre><code>HBRUSH CMyDialog::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)
{
HBRUSH hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor);
if(bSetBkTransparent_)
{
pDC->SetBkMode(TRANSPARENT);
hbr = (HBRUSH)GetStockObject(NULL_BRUSH);
}
return hbr;
}
</code></pre>
<p>It works fine for all the controls but the group-box (CStatic). All the labels (CStatic) are been painted with a transparent text background but the text of the group box it is not transparent.</p>
<p>I already googled for this but I didn't find a solutions. Does anybody know how to make a real transparent group-box?</p>
<p>By the way, I am working in Windows XP. And I don't want to fully draw the control to avoid having to change the code if the application is migrated to another OS.</p>
<p>Thanks,</p>
<p>Javier</p>
<p>Note: I finally changed the dialog so that I don't need to make it transparent. Anyway, I add this information because maybe someone is still trying to do it. The groupbox isn't a CStatic but a CButton (I know this is not new). I changed the Windows XP theme to Windows classic and then the groupbox backgraund was transparent. The bad new is that in this case the frame line gets visible beneath the text...so if someone is following this approach I think maybe he/she would better follow the Adzm's advice. </p>

<p>I'm trying to figure out if there's a reasonably efficient way to perform a lookup in a dictionary (or a hash, or a map, or whatever your favorite language calls it) where the keys are regular expressions and strings are looked up against the set of keys. For example (in Python syntax):</p>
<pre><code>>>> regex_dict = { re.compile(r'foo.') : 12, re.compile(r'^FileN.*$') : 35 }
>>> regex_dict['food']
12
>>> regex_dict['foot in my mouth']
12
>>> regex_dict['FileNotFoundException: file.x does not exist']
35
</code></pre>
<p>(Obviously the above example won't work as written in Python, but that's the sort of thing I'd like to be able to do.)</p>
<p>I can think of a naive way to implement this, in which I iterate over all of the keys in the dictionary and try to match the passed in string against them, but then I lose the O(1) lookup time of a hash map and instead have O(n), where n is the number of keys in my dictionary. This is potentially a big deal, as I expect this dictionary to grow very large, and I will need to search it over and over again (actually I'll need to iterate over it for every line I read in a text file, and the files can be hundreds of megabytes in size).</p>
<p>Is there a way to accomplish this, without resorting to O(n) efficiency?</p>
<p>Alternatively, if you know of a way to accomplish this sort of a lookup in a database, that would be great, too.</p>
<p>(Any programming language is fine -- I'm using Python, but I'm more interested in the data structures and algorithms here.)</p>
<p>Someone pointed out that more than one match is possible, and that's absolutely correct. Ideally in this situation I'd like to return a list or tuple containing all of the matches. I'd settle for the first match, though.</p>
<p>I can't see O(1) being possible in that scenario; I'd settle for anything less than O(n), though. Also, the underlying data structure could be anything, but the basic behavior I'd like is what I've written above: lookup a string, and return the value(s) that match the regular expression keys.</p>

<p>I've been developing a few JSF applications lately and am disturbed with the inconsistency in the web component APIs. </p>
<p>I've noticed that there is extremely unpredictable behavior when calling .getValue() or .getSubmittedValue() on a JSF component object in server side code. Sometimes when I call .getValue() on a drop down list box, I've noticed that I get the value as it was BEFORE I selected my value (so the value from the last page refresh), of which .getSubmittedValue() gets me the correct value, as such:</p>
<pre><code>UIInput name = new UIInput(); // This is the control I have in a bean.
public void submit(ActionEvent ae)
{
someMethod(name.getValue().toString()); // Retrieves the "old" value
someMethod(name.getSubmittedValue().toString()); // Retrieves the correct value
}
</code></pre>
<p>Also, I've noticed that calling .getSubmittedValue() on a form field sometimes results in a null pointer exception because that value has not been instantiated in the component object, in which case when I call .getValue() in that circumstance I get the correct value, for example:</p>
<pre><code>HtmlInputText name = new HtmlInputText(); // This is the control I have in a bean.
public void submit(ActionEvent ae)
{
someMethod(name.getValue().toString()); // Retrieves the correct value
someMethod(name.getSubmittedValue().toString()); // Throws NullPointerException
}
</code></pre>
<p>Is this just a "quirk" of the JSF framework, or am I just using the API <strong>COMPLETELY</strong> incorrectly?? Any insight into these two methods would be greatly appreciated. Cheers.</p>

<p>I am trying to use an XML-RPC server on my Drupal (PHP) backend to make it easier for my Perl backend to talk to it. However, I've run into an issue and I'm not sure which parts, if any, are bugs. Essentially, some of the variables I need to pass to Drupal are strings that sometimes are strings full of numbers and the Drupal XML-RPC server is returning an error that when a string is full of numbers it is not properly formed.</p>
<p>My Perl code looks something like this at the moment.</p>
<pre><code>use strict;
use warnings;
use XML::RPC;
use Data::Dumper;
my $xmlrpc = XML::RPC->new(URL);
my $result = $xmlrpc->call( FUNCTION, 'hello world', '9876352345');
print Dumper $result;
</code></pre>
<p>The output is:</p>
<pre><code>$VAR1 = {
'faultString' => 'Server error. Invalid method parameters.',
'faultCode' => '-32602'
};
</code></pre>
<p>When I have the Drupal XML-RPC server print out the data it receives, I notice that the second argument is typed as i4:</p>
<pre><code><param>
<value>
<i4>9876352345</i4>
</value>
</code></pre>
<p>I think when Drupal then finishes processing the item, it is typing that variable as an int instead of a string. This means when Drupal later tries to check that the variable value is properly formed for a string, the is_string PHP function returns false.</p>
<pre><code>foreach ($signature as $key => $type) {
$arg = $args[$key];
switch ($type) {
case 'int':
case 'i4':
if (is_array($arg) || !is_int($arg)) {
$ok = FALSE;
}
break;
case 'base64':
case 'string':
if (!is_string($arg)) {
$ok = FALSE;
}
break;
case 'boolean':
if ($arg !== FALSE && $arg !== TRUE) {
$ok = FALSE;
}
break;
case 'float':
case 'double':
if (!is_float($arg)) {

<p>What I'm not sure about is on which side of the divide the issue lies or if there is something else I should be using. Should the request from the Perl side be typing the content as a string instead of i4 or is the Drupal side of the request too stringent for the string type? My guess is that the issue is the latter, but I don't know enough about how an XML-RPC server is supposed to work to know for sure.</p>

<p>A colleague is looking to generate UML class diagrams from heaps of Python source code.
He's primarily interested in the inheritance relationships, and mildly interested in compositional relationships, and doesn't care much about class attributes that are just Python primitives.</p>
<p>The source code is pretty straightforward and not tremendously evil--it doesn't do any fancy metaclass magic, for example. (It's mostly from the days of Python 1.5.2, with some sprinklings of "modern" 2.3ish stuff.) </p>
<p>What's the best existing solution to recommend?</p>

<p>I have a query in which I am pulling the runtime of an executable. The database contains its start time and its end time. I would like to get the total time for the run.
So far I have:</p>
<pre><code>SELECT startTime, endTime,
cast(datediff(hh,starttime,endtime) as varchar)
+':'
+cast(datediff(mi,starttime,endtime)-60*datediff(hh,starttime,endtime) as varchar) AS RUNTIME
FROM applog
WHERE runID = 33871
ORDER BY startTime DESC
</code></pre>
<p>When I execute this I get expected values and also some unexpected.
For example, if starttime = 2008-11-02 15:59:59.790 and endtime = 2008-11-02 19:05:41.857 then the runtime is = 4:-54.
How do I get a quere in MS SQL SMS to return the value 3:06 for this case?</p>
<p>Thanks.</p>
<p>Eoin Campbell's I selected as the answer is the most bulletproof for my needs. David B's is do-able as well.</p>

<p>I'm using jQuery and wanting to target the nth <li> in a list after clicking the nth link.</p>
<pre><code><ul id="targetedArea">
<li></li>
<li></li>
<li></li>
<li></li>
</ul>
<div id="clickedItems">
<a></a>
<a></a>
<a></a>
<a></a>
</div>
</code></pre>
<p>I can target them individually, but I know there must be a faster way by passing which <a> element I clicked on.</p>
<pre><code>$("#clickedItem a:eq(2)").click(function() {
$("#targetedArea:eq(2)").addClass('active');
return false;
});
</code></pre>
<p>Cheers,<br />
Steve </p>

<p>I want to select records that are 1 month old or newer.</p>
<p>The query is: SELECT * FROM foobar WHERE created_at > DATE_SUB(curdate(), INTERVAL 1 MONTH)</p>
<p>Using Propel in Symfony, I do:</p>
<blockquote>
<p>$c = new Criteria<br>
$c->add(FoobarPeer::CREATED_AT, "DATE_SUB(curdate(), INTERVAL 1 MONTH)", Criteria::GREATER_THAN); </p>
</blockquote>
<p>What Propel generates is: SELECT * FROM foobar WHERE created_at > 'DATE_SUB(curdate(), INTERVAL 1 MONTH)' - in other words, it puts the MySQL function in single quotes, which makes it a (meaningless) string and I get no records.</p>
<p>What I've done for now is:</p>
<blockquote>
<p>$c->add(FoobarPeer::CREATED_AT, "created_at > DATE_SUB(curdate(), INTERVAL 1 MONTH)", Criteria::CUSTOM); </p>
</blockquote>
<p>But I don't want to use custom workarounds unless I have to. Any hints besides using Criteria::CUSTOM?</p>

<p>I've created a Visual Basic WPF Application project that contains Toy.edmx, an ADO.NET Entity Data Model generated from a database called Toy.</p>
<p>Its <em>Window1.xaml.vb</em> file looks like this:</p>
<pre>
1 Class Window1
2
3 Private Sub Window1_Loaded( _
4 ByVal sender As System.Object, _
5 ByVal e As System.Windows.RoutedEventArgs) _
6 Handles MyBase.Loaded
7
8 Dim dc As New ToyEntities1
9 Label1.Content = (From c As Client In dc.ClientSet _
10 Select c).First.FirstName
11
12 End Sub
13
14 End Class
</pre>
<p>That runs just fine.</p>
<p>But, if I add the file <em>Client.vb</em>...</p>
<pre>
1 Partial Public Class Client
2 Function IsWashington() As Boolean
3 Return Me.LastName = "Washington"
4 End Function
5 End Class
</pre>
<p>...and add a WHERE clause to my <em>Window1.xaml.vb</em> query...</p>
<pre>
9 Label1.Content = (From c As Client In dc.ClientSet _
10 Where c.IsWashington _
11 Select c).First.FirstName
</pre>
<p>...then I get this NotSupportedException:</p>
<blockquote>
<p>LINQ to Entities does not recognize the method 'Boolean IsWashington()' method, and this method cannot be translated into a store expression.</p>
</blockquote>
<p>How do I extend ADO.NET Entity Framework objects with partial classes?</p>

<p>Consider the following simple C program that read a file into a buffer and displays that buffer to the console:</p>
<pre><code>#include<stdio.h>
main()
{
FILE *file;
char *buffer;
unsigned long fileLen;
//Open file
file = fopen("HelloWorld.txt", "rb");
if (!file)
{
fprintf(stderr, "Unable to open file %s", "HelloWorld.txt");
return;
}
//Get file length
fseek(file, 0, SEEK_END);
fileLen=ftell(file);
fseek(file, 0, SEEK_SET);
//Allocate memory
buffer=(char *)malloc(fileLen+1);
if (!buffer)
{
fprintf(stderr, "Memory error!");
fclose(file);
return;
}
//Read file contents into buffer
fread(buffer, fileLen, 1, file);
//Send buffer contents to stdout
printf("%s\n",buffer);
fclose(file);
}
</code></pre>
<p>The file it will read simply contains: </p>
<blockquote>
<p>Hello World!</p>
</blockquote>
<p>The output is:</p>
<blockquote>
<p>Hello World!²²²²▌▌▌▌▌▌▌↔☺</p>
</blockquote>
<p>It has been a while since I did anything significant in C/C++, but normally I would assume the buffer was being allocated larger than necessary, but this does not appear to be the case. </p>
<p>fileLen ends up being 12, which is accurate.</p>
<p>I am thinking now that I must just be displaying the buffer wrong, but I am not sure what I am doing wrong. </p>
<p>Can anyone clue me in to what I am doing wrong?</p>

<p>I know that php has md5(), sha1(), and the hash() functions, but I want to create a hash using the MySQL PASSWORD() function. So far, the only way I can think of is to just query the server, but I want a function (preferably in php or Perl) that will do the same thing without querying MySQL at all.</p>
<p>For example:</p>
<p>MySQL hash -> 464bb2cb3cf18b66</p>
<p>MySQL5 hash -> *01D01F5CA7CA8BA771E03F4AC55EC73C11EFA229</p>

<p>I have a web-app that I would like to extend to support multiple languages with new URLs. For example, www.example.com/home.do stays English, but www.example.com/es/home.do is Spanish. My first thought was to create a Filter which rewrites incoming urls like /es/home.do to /home.do (and sets the Locale in the Request); this works fine. The Filter wraps the ServletRequest with an HttpServletRequestWrapper which overrides getContextPath() to return the language:</p>
<pre><code>class FakeContextRequest extends HttpServletRequestWrapper {
private String context = "";
FakeContextRequest(HttpServletRequest request, String context) {
super(request);
// snip some validation code
this.context = request.getContextPath() + context;
}
@Override
public String getContextPath() {
return this.context;
}
}
</code></pre>
<p>My Filter forwards to the appropriate request as follows:</p>
<pre><code>FakeContextRequest fr = new FakeContextRequest(request, lang);
fr.getRequestDispatcher(newResourceName).forward(fr, response);
</code></pre>
<p>My problem is that the next servlet doesn't forward properly. The next servlet (typically a Struts ActionServlet) forwards to a JSP (often using Struts Tiles); when I get to the JSP the HttpServletRequest has been wrapped several times and the object in question reports the context to be empty (the root context, which is where the application is actually deployed).</p>
<p>I want the context to be re-written so that all my context-aware code that already exists can automatically insert the language into the URLs that are written. Is this possible?</p>
<p><strong>Edit:</strong> I solved my problem by using a wrapped HttpServletResponse instead of a wrapped HttpServletRequest; I rewrite the URL in the response.encodeURL() method.</p>

<pre><code>TTest<T> = class
private
f : T;
public
function ToString : string;
end;
</code></pre>
<p>If is an object then this should work</p>
<pre><code>TTest<T>.ToString;
begin
Result := f.ToString;
end;
</code></pre>
<p>But what happens when is say an integer? This would be ok in .net. of course.</p>
<p>I know it won't work, but how do I code this to work with objects AND simple types?</p>

<p>I'm writing a simple C++ class in which I would like cache picture thumbnails versions of images downloaded from the web. As such, I would like to use a hash function which takes in URL strings and outputs a unique string suitable as a filename.</p>
<p>Is there a simple way to do this without re-writing the function myself? I searched around for a simple library, but couldn't find anything. Surely this is a common problem.</p>

<p>Folks,</p>
<p>I am pulling all my Flash (pure AS3 project, not Flash CS3) content from a Drupal back-end for SEO purposes. This works great, except the HTML rendering built into the TextField object leaves a lot to be desired. Could anyone recommend any libraries that would allow me to display HTML elements? At this stage, commercial or open-source libraries are welcome.</p>
<p>Thanks,
Marcus</p>

<p>I have a file and I don't know how big it's going to be (it could be quite large, but the size will vary greatly). I want to search the last 10 lines or so to see if any of them match a string. I need to do this as quickly and efficiently as possible and was wondering if there's anything better than:</p>
<pre><code>s = "foo"
last_bit = fileObj.readlines()[-10:]
for line in last_bit:
if line == s:
print "FOUND"
</code></pre>

<p>I've got a canvas that's 800x600 inside a window that's 300x300. When I press a certain key, I want it the canvas to move in that direction.<br>
I've done this inside the window's code behind:</p>
<pre>
protected override void OnKeyDown(KeyEventArgs e)
{
base.OnKeyDown(e);
Key keyPressed = e.Key;
if (keyPressed == Key.W)
{
gcY += 5;
}
if (keyPressed == Key.S)
{
gcY -= 5;
}
if (keyPressed == Key.A)
{
gcX += 5;
}
if (keyPressed == Key.D)
{
gcX -= 5;
}
gameCanvas.RenderTransform = new TranslateTransform(gcX, gcY);
}
</pre>
<p>Well, it works, but the movement is jerky. And if I hold on to a key, <kbd>W</kbd> for instance, then it pauses for a split second, before moving.<br>
Is there anyway to make the movement smoother and to get rid of the pause when you hold down a key?<br>
Thanks.</p>

<p>How does an application perform a proximity search? For example, a user types in a postal code, then the application lists all the businesses within 20 miles ordered by proximity.</p>
<p>I want to build something like that in PHP and MySQL. Is this approach correct?</p>
<ol>
<li>Get the addresses for locations I'm interested in and store in my database</li>
<li>Geocode all the addresses with Google's geocoding service</li>
<li>Write a database query that includes Haversine formula to do the proximity search and ordering </li>
</ol>
<p>Is this OK? In step 3, I'm going to calculate the proximity for every query. Is it better to have a PROXIMITY table that lists the distance between every business and a few reference locations?</p>

<p>I'm currently in the process of testing our solution that has the whole "gamut" of layers: UI, Middle, and the omnipresent Database.</p>
<p>Before my arrival on my current team, query testing was done by the testers manually crafting queries that would theoretically return a result set that the stored procedure should return based on various relevancy rules, sorting, what have you.</p>
<p>This had the side effect of bugs being filed against the tester's query more often than against the actual query in question.</p>
<p>I proposed actually working with a known result set that you could just infer how it should return since you control the data present -- previously, data was pulled from production, sanitized, and then populated in our test databases.</p>
<p>People were still insistent on creating their own queries to test what the developers have created. I suspect that many still are. I have it in my mind that this isn't ideal at all, and just increases our testing footprint needlessly.</p>
<p>So, I'm curious, which practices do you use to test scenarios like this, and what would be considered ideal for the best end-to-end coverage you can get, without introducing chaotic data?</p>
<p>The issue I have is where's the best place to do what testing. Do I just poke the service directly, and compare that dataset to that which I can pull from the stored procedure? I have a rough idea, and have been successful enough so far, but I feel like we're still missing something important here, so I'm looking to the community to see if they have any valuable insights that might help formulate my testing approach better.</p>

<p>I am experimenting for the first time with css layouts and my experience with CSS is very basic. What I want to achieve is a 2 column layout: left panel and content.<br>
I have found this:</p>
<pre><code>#leftcontent
{
position: absolute;
left: 10px;
top: 10px;
width: 170px;
border: 1px solid #C0C0C0;
padding: 2px;
}
#centercontent
{
position: absolute;
margin-left: 181px;
border:1px solid #C0C0C0;
top: 10px;
//fix IE5 bug
voice-family: "\"}\"";
voice-family: inherit;
margin-left: 181px;
}
</code></pre>
<p>This displays great in firefox but the content in IE8 goes off the right of the screen, I assume by the length of the <code>#leftcontent</code>. How can I fix this?</p>
<p>This is probably quite a simple fix but I have experimented and looked for fixes, but this supposedly should work. I appreciate any help.</p>

<p>I occasionally work on an old project that uses classic asp as a front end and an access database as a backend.</p>
<p>I'd like to create a new column in one of the tables that contains logic to calculate its value from the other columns in the row.</p>
<p>I know how to do this in a more modern DBMS, but I don't think that access supports it. Keep in mind I'm not using the access frontend, just the Jet DB engine via ODBC.</p>
<p>Any pointers?</p>

<p>I have a base class with an optional virtual function</p>
<pre><code>class Base {
virtual void OnlyImplementThisSometimes(int x) {}
};
</code></pre>
<p>When I compile this I get a warning about the unused param x. Is there some other way I should have implemented the virtual function? I have re-written it like this:</p>
<pre><code>class Base {
virtual void OnlyImplementThisSometimes(int x)
{
x = 0;
}
};
</code></pre>
<p>I also have the problem that if I'm not careful, the subclass I make can implement the wrong function and then I don't notice because of overloading: e.g.</p>
<pre><code>class Derived : public Base {
void OnlyImplementThisSometimes(int x, int y) { // some code }
};
Derived d;
Base *b = dynamic_cast<Base *>(&d);
b->OnlyImplementThisSometimes(x); // calls the method in the base class
</code></pre>
<p>The base class method was called because I implemented the derived function with an "int y" param but there is no warning about this. Are these just common pitfalls in C++ or have I misunderstood virtual functions?</p>

$dirname = "images/";
$images = scandir($dirname);
$dh = opendir($dirname);
while ($file = readdir($dh)) {
if (substr($file, -4) == ".gif") {

closedir($dh);

<p>I have an iphone app where I call these three functions in appDidFinishLaunching:</p>
<pre><code>glMatrixMode(GL_PROJECTION);
glOrthof(0, rect.size.width, 0, rect.size.height, -1, 1);
glMatrixMode(GL_MODELVIEW);
</code></pre>
<p>When stepping through with the debugger I get EXC BAD ACCESS when I execute the first line. Any ideas why this is happening?</p>
<p>Btw I have another application where I do the same thing and it works fine. So I've tried to duplicate everything in that app (#imports, adding OpenGLES framework, etc) but now I'm just stuck.</p>

<p>I have a list of stores, departments within the stores, and sales for each department, like so (created using max(sales) in a subquery, but that's not terribly important here I don't think):</p>
<pre><code>toronto baskets 500
vancouver baskets 350
halifax baskets 100
toronto noodles 275
vancouver noodles 390
halifax noodles 120
halifax fish 200
</code></pre>
<p>I would like to ask for the highest-selling department at each store. The results should look like this:</p>
<pre><code>toronto baskets 500
vancouver noodles 275
halifax fish 200
</code></pre>
<p>Whenever I use GROUP BY, it includes all the listings from my subquery. Is there a nice clean way to do this without a temporary table?</p>

<p><strong>Short version</strong></p>
<p>If I split my users into shards, how do I offer a "user search"? Obviously, I don't want every search to hit every shard.</p>
<p><strong>Long version</strong></p>
<p>By shard, I mean have multiple databases where each contains a fraction of the total data. For (a naive) example, the databases UserA, UserB, etc. might contain users whose names begin with "A", "B", etc. When a new user signs up, I simple examine his name and put him into the correct database. When a returning user signs in, I again look at his name to determine the correct database to pull his information from.</p>
<p>The advantage of sharding vs read replication is that read replication does not scale your writes. All the writes that go to the master have to go to each slave. In a sense, they all carry the same write load, even though the read load is distributed.</p>
<p>Meanwhile, shards do not care about each other's writes. If Brian signs up on the UserB shard, the UserA shard does not need to hear about it. If Brian sends a message to Alex, I can record that fact on both the UserA and UserB shards. In this way, when either Alex or Brian logs in, he can retrieve all his sent and received messages from his own shard without querying all shards.</p>
<p>So far, so good. What about searches? In this example, if Brian searches for "Alex" I can check UserA. But what if he searches for Alex by his last name, "Smith"? There are Smiths in every shard. From here, I see two options:</p>
<ol>
<li>Have the application search for Smiths on each shard. This can be done slowly (querying each shard in succession) or quickly (querying each shard in parallel), but either way, every shard needs to be involved in every search. In the same way that read replication does not scale writes, having searches hit every shard does not scale your searches. You may reach a time when your search volume is high enough to overwhelm each shard, and adding shards does not help you, since they all get the same volume.</li>
<li>Some kind of indexing that itself is tolerant of sharding. For example, let's say I have a constant number of fields by which I want to search: first name and last name. In addition to UserA, UserB, etc. I also have IndexA, IndexB, etc. When a new user registers, I attach him to each index I want him to be found on. So I put Alex Smith into both IndexA and IndexS, and he can be found on either "Alex" or "Smith", but no substrings. In this way, you don't need to query each shard, so search might be scalable.</li>
</ol>
<p>So can search be scaled? If so, is this indexing approach the right one? Is there any other?</p>

<p>I have a C program with an embedded Perl interpreter. I want to be able to precompile some Perl code from within the program. How do I do that?</p>
<p>Rationale (if anyone is interested) is to be able to compile it once, store the parse tree, and execute many times (as long as the compiled code does not change).</p>
<p>Thanks!
Madhu</p>
<p>PS: I am using Perl-5.8, though it would be good to know if Perl-6.0 makes this easier in any way.</p>

<p>This physical path is: C:\ESI\HR_Connect2\BenefitChangeSystem\Application_DEV\Web\SysCoord.</p>
<p>Any ideas would be appreciated.</p>
<p><strong>Update 1</strong></p>
<p>Added the following to my web.config file per this article. Also made the web.config writable and killed/restarted the development web server. No change in behavior.</p>
<pre><code><location path="VSEnterpriseHelper.axd">
<system.web>
<authorization>
<allow users="*"/>
</authorization>
</system.web>
</location>
</code></pre>
<p><strong>Update 2</strong></p>
<p>Changing the AspNetDevelopmentServerHost attribute to the equivalent of [AspNetDevelopmentServerHost("%PathToWebRoot%\solutionfolder\webfolder", "/webfolder")] resolved the 404 problem.</p>
<p>Unfortunately the test began to return a 500 error instead. Progress, but not much. Trial and error with a clean project led to the conclusion that references to custom classes in the of the web.config were causing the problem.</p>
<p>For example:</p>
<pre><code> <profile enabled="true" defaultProvider="MyProfileProvider">
<providers>
<add name="MyProfileProvider" connectionStringName="ProfileConnectionString" applicationName="/MyApp" type="System.Web.Profile.SqlProfileProvider"/>
</providers>
<properties>
<add name="Theme" type="String" defaultValue="Default"/>
<add name="LastLogon" type="DateTime"/>
<add name="LastLogonIp" type="String"/>
<!--
<add name="EmployeeSearchCriteria" type="MyApplicationFramework.Profile.EmployeeSearchCriteria"/>
<add name="DocumentSearchCriteria" type="MyApplicationFramework.Profile.DocumentSearchCriteria"/>
-->
</properties>
</profile>
</code></pre>
<p>With the criteria types above commented out the test ran fine. With them uncommented, the 500 error was returned.</p>
<p>Anyone had a similar problem in the past?</p>

<p>Disclaimer: the following is a sin against XML. That's why I'm trying to change it with XSLT :)</p>
<p>My XML currently looks like this:</p>
<pre><code><root>
<object name="blarg" property1="shablarg" property2="werg".../>
<object name="yetanotherobject" .../>
</root>
</code></pre>
<p>Yes, I'm putting all the textual data in attributes. I'm hoping XSLT can save me; I want to move toward something like this:</p>
<pre><code><root>
<object>
<name>blarg</name>
<property1>shablarg</name>
...
</object>
<object>
...
</object>
</root>
</code></pre>
<p>I've actually got all of this working so far, with the exception that my sins against XML have been more... exceptional. Some of the tags look like this:</p>
<pre><code><object description = "This is the first line
This is the third line. That second line full of whitespace is meaningful"/>
</code></pre>
<p>I'm using xsltproc under linux, but it doesn't seem to have any options to preserve whitespace. I've attempted to use xsl:preserve-space and xml:space="preserve" to no avail. Every option I've found seems to apply to keeping whitespace within the elements themselves, but not the attributes. Every single time, the above gets changed to:</p>
<pre>
This is the first line This is the third line. That second line full of whitespace is meaningful
</pre>
<p>So the question is, can I preserve the attribute whitespace?</p>

<p>I currently have two text boxes which accept any number. I have a text block that takes the two numbers entered and calculates the average. </p>
<p>I was wondering if there was a way I could bind this text block to both text boxes and utilize a custom converter to calculate the average? I currently am catching the text changed events on both text boxes and calculating the average that way, but I am under the assumption data binding would be more efficient and easier.</p>

<p>In class, we are all 'studying' databases, and everyone is using Access. Bored with this, I am trying to do what the rest of the class is doing, but with raw SQL commands with MySQL instead of using Access.</p>
<p>I have managed to create databases and tables, but now how do I make a relationship between two tables?</p>
<p>If I have my two tables like this:</p>
<pre><code>CREATE TABLE accounts(
account_id INT NOT NULL AUTO_INCREMENT,
customer_id INT( 4 ) NOT NULL ,
account_type ENUM( 'savings', 'credit' ) NOT NULL,
balance FLOAT( 9 ) NOT NULL,
PRIMARY KEY ( account_id )
)
</code></pre>
<p>and</p>
<pre><code>CREATE TABLE customers(
customer_id INT NOT NULL AUTO_INCREMENT,
name VARCHAR(20) NOT NULL,
address VARCHAR(20) NOT NULL,
city VARCHAR(20) NOT NULL,
state VARCHAR(20) NOT NULL,
PRIMARY KEY ( customer_id )
)
</code></pre>
<p>How do I create a 'relationship' between the two tables? I want each account to be 'assigned' one customer_id (to indicate who owns it).</p>

<p>Question: Is there an easy way (library function) to perform a bitwise AND or OR on numbers larger than 32-bit in ActionScript? </p>
<p>From the docs:
"Bitwise operators internally manipulate floating-point numbers to change them into 32-bit integers. The exact operation performed depends on the operator, but all bitwise operations evaluate each binary digit (bit) of the 32-bit integer individually to compute a new value."</p>
<p>Bummer...</p>
<p>I can't use the & or | ops - does AS expose a library function to do this for Numbers?</p>
<p>Specifics: I'm porting a bunch of java to flex and the java maintains a bunch of 'long' masks. I know that I can split the Java masks into two ints on the flex side. Since all of my mask manip is localized this won't be too painful. However, I'd like to keep the port as 1-1 as possible.</p>
<p>Any suggestions?
Thanks!</p>

<p>I have some cross platform DNS client code that I use for doing end to end SMTP and on windows I can find the current DNS server ip addresses by looking in the registry. On the Mac I can probably use the SystemConfiguration framework as mentioned in the first answer, however the exact method of doing so is not immediately obvious.</p>
<p>For instance SCDynamicStoreCopyDHCPInfo returns some of the dynamic DHCP related data but not the DNS server addresses.</p>

<p>I am having a problem getting a list of fields from a query defined at run time by the users of my program. I let my users enter a SQL query into a memo control and then I want to let them go through the fields that will return and do such things as format the output, sum column values and so forth. So, I have to get the column names so they have a place to enter the additional information.</p>
<p>I would do fine if there were no parameters, but I also have to let them define filter parameters for the query. So, if I want to set the parameters to null, I have to know what the parameter's datatype is.</p>
<p>I am using Delphi 2006. I connect to a Firebird 2.1 database using the DBExpress component TSQLConnection and TSQLQuery. Previously, I was successful using:</p>
<p>for i := 0 to Qry.Params.Count - 1 do Qry.Params[i].value := varNull;</p>
<p>I discovered I had a problem when I tried to use a date parameter. It was just a coincidence that all my parameters up until then had been integers (record IDs). It turns out that varNull is just an enumerated constant with a value of 1 so I was getting acceptable results (no records) was working okay.</p>
<p>I only need a list of the fields. Maybe I should just parse the SELECT clause of the SQL statement. I thought setting Qry.Prepared to True would get me a list of the fields but no such luck. It wants values for the parameters. </p>
<p>If you have an idea, I would sure like to hear it. Thanks for any help.</p>

<p>I am developing an iPhone application, in my table view I wanted custom color for Cell Selection Style, I read the <em>UITableViewCell Class Reference</em> but there are only three constants defined for Selection style (Blue, Gray, None). I saw one application that used a different color than those defined in the reference.</p>
<p>How can we use a color other than those defined in the reference?</p>

<p>How have you explained nested arrays to a programmer. I'm thinking someone that has an entry level understanding of programming, but is trying to do more complicated coding.</p>
<p>The array with array works, but they can't quite get their mind around the idea.</p>
<p><strong>Edit:</strong> example of a nested array:</p>
<pre><code>array(
'array1' => array(
'key1' => 'val1',
'key2' => 'val2',
),
'array2' => array(
'key1' => 'val1',
'key2' => 'val2',
),
);
</code></pre>
<p>Of course, they are usually more complicated than this and maybe that's the problem.</p>

<p>I'm tasked with replicating a production environment to create many test/sit environments.</p>
<p>One of the things I need to do is build up Perl, with all the modules which have been installed (including internal and external modules) over the years. I could just use CPAN.pm autobundle, but this will result in the test environment having much newer versions of the external modules that production has.</p>
<p>What is the easiest/best way to get and install (a lot of) version specific Perl modules.</p>

<p>My question is how do I configure an EJB 3.0 style message driven bean to use a configured JMS datasource in jboss. </p>
<p>For example, my MDB looks something like:</p>
<pre><code>@MessageDriven(mappedName = "ExampleMDB", activationConfig = {
@ActivationConfigProperty(propertyName = "destinationType", propertyValue = "javax.jms.Topic"),
@ActivationConfigProperty(propertyName = "destination", propertyValue = "MyTopic"),
@ActivationConfigProperty(propertyName = "channel", propertyValue = "MyChannel"),
})
@ResourceAdapter(value = "wmq.jmsra.rar")
@TransactionAttribute(TransactionAttributeType.NOT_SUPPORTED)
@TransactionManagement(TransactionManagementType.BEAN)
public class MyMDB implements MessageListener {
.....
}
</code></pre>
<p>But I would like the bean to attached to a given JMS datasource ( in the case of jboss 4.2.2 this is in deploy/jms/jms-ds.xml). Perhaps this is not even possible but is worth asking.</p>

<p>How can I get that working in CodeIgniter?</p>

<p>Is there a PHP class/library that would allow me to query an XHTML document with CSS selectors? I need to scrape some pages for data that is very easily accessible if I could somehow use CSS selectors (jQuery has spoiled me!). Any ideas?</p>
