<p>Can anyone give me an example of what the Artifact paths setting defined for a build configuration could look like if I want to create two artifacts dist and source where I am using the sln 2008 build runner and building my projects using the default bin/Release?</p>
<pre>
**/Source/Code/MyProject/bin/Release/*.* => dist
**/*.* => source
</pre>
<p>I get two artifact roots dist and source but under dist I get the whole directory structure (Source/Code/MyProject/bin/Release) which I don't want and under source I get the whole thing along with obj and bin/Release which I do not want.</p>
<p>Can you give some advice on how to do this correctly?</p>
<p>Do I need to change the target location for all the projects I am building to be able to get this thing to work?</p>

<p>I have webservice which is passed an array of ints.
I'd like to do the select statement as follows but keep getting errors. Do I need to change the array to a string?</p>
<pre><code>[WebMethod]
public MiniEvent[] getAdminEvents(int buildingID, DateTime startDate)
{
command.CommandText = @"SELECT id,
startDateTime, endDateTime From
tb_bookings WHERE buildingID IN

SqlParameter buildID = new SqlParameter("@buildingIDs", buildingIDs);

<p>If I have two tables... Category and Pet. </p>
<p>Is there a way in LINQ to SQL to make the result of the joined query map to a another strongly typed class (such as: PetWithCategoryName) so that I can strongly pass it to a MVC View?</p>
<p>I currently have Category and Pet classes... should I make another one?</p>
<p>Maybe I missing something here. Can any of you enlighten me?</p>
<pre><code>from p in petTable
join c in categoryTable on p.CategoryId equals c.Id
where (c.Id == categoryId.Value)
select new

p.Id,

CategoryName = c.Name

<p>The situation is like this : Main project A. and a class library B. <strong>A references B</strong></p>
<p>Project B has the classes that will be serialized. The classes are used in A. Now, the problem appears when from Project A I try to serialize the objects from B. An exception is thrown that says a class from A cannot be serialized. This is the strange part since in the classes in B I cant have a reference to those in A. (a circular dependency would be created).</p>
<p>How can I track down the problem ? because the exception method doesn't say where the Problem appeared ?</p>
<p><strong>Edit :</strong>
Ok, I found the problem with the help of <strong>Kent Boogaart's</strong> small app :D . I have a PropertyChanged listener in a class in project A that is not marked Serializable - and I don't want to mark it so. ( it would serialize that class to right ?)</p>
<p>I've solved the problem with the event by following this link : <a href="http://www.lhotka.net/weblog/CommentView,guid,776f44e8-aaec-4845-b649-e0d840e6de2c.aspx#commentstart" rel="nofollow noreferrer">.NET 2.0 solution to serialization of objects that raise events</a>.
There still is a problem , but it's probably something similar.</p>
<p><strong>PS:</strong> Great tool from <strong>Kent Boogaart</strong></p>

<p>Simplified, I have an application where data is intended to flow over the internet between two servers. Ideally, I'd like to test at what point the software ceases to function. At what lowerbound limit (bandwidth, latency, dropped packets) do things stop working to test the reliability of the software.</p>
<p>What I thought I would do was the following:</p>
<ol>
<li>Setup up 3 machines (VMware instances) </li>
<li>Install the 2 applications on two of the servers.</li>
<li>Setup up the 3rd server to sit between the two machines by doing some sort of magic with Routing and Remote Access on Windows 2003</li>
<li>Install either <a href="http://bandwidthcontroller.com/trafficShaperXp.html" rel="noreferrer">Traffic Shaper XP</a> or <a href="http://netlimiter.com/" rel="noreferrer">NetLimiter</a> to limit the bandwidth</li>
<li>Run something like <a href="http://www.tmurgent.com/download%5CTMnetsim32_02040000.zip" rel="noreferrer">TMnetSim Network Simulator</a> to simulate a bad connection.</li>
</ol>
<p>Does this sound like a good idea or are there easier/better ways of doing this? I'm not that comfortable on Linux and my team mates are even less so.</p>

<p>I cureently have a set up like below </p>
<pre><code>Public ClassA
property _classB as ClassB
End Class
Public ClassB
property _someProperty as someProperty
End Class
</code></pre>
<p>what I want to do is to databind object A to a gridview with one of the columns being databound to ClassB._someProperty. When I try to databind it as Classb._someProperty I get a "Field or Property not found on Selected Datasource" error</p>
<p>I have tried to use the objectContainerDataSource and also directly binding to the gridview with no success. </p>
<p>Has anyone come across this in the past?</p>

<p>given a matrix of distances between points is there an algorithm for determining a set of n-dimensional points that has these distances? (or at least minimises the error) </p>
<p>sort of like a n-dimensional version of the turnpike problem.</p>
<p>The best I can come up with is using multidimensional scaling.</p>

<p>I am writing a Time Sheeting web application that involves users entering their tasks for the week. I would like not to have the page refresh so I am exploring ways to add/delete/edit tasks using JavaScript on the client browser. </p>
<p>Currently I am using ASP.NET-MVC, Ajax, JQuery and LiveValidation and I am make steady (if slow) progress.</p>
<p>I am interested to see if this is a solved problem and the pros and cons of various approaches.</p>
<p>For example my current approach to adding a new task (Category/Activity/Hours) involves basic validation using LiveValidation with a web service call to check the Category/Activity. If all the fields validate I create a new table row to show the task and the hide it. Next I call the web service again to add the task to the DB and on success I show the new row and enable it for deletion/editing</p>

<p>I want to record user states and then be able to report historically based on the record of changes we've kept. I'm trying to do this in SQL (using PostgreSQL) and I have a proposed structure for recording user changes like the following.</p>
<pre><code>CREATE TABLE users (
userid SERIAL NOT NULL PRIMARY KEY,
name VARCHAR(40),
status CHAR NOT NULL
);
CREATE TABLE status_log (
logid SERIAL,
userid INTEGER NOT NULL REFERENCES users(userid),
status CHAR NOT NULL,
logcreated TIMESTAMP
);
</code></pre>
<p>That's my proposed table structure, based on the data.</p>
<p>For the status field 'a' represents an active user and 's' represents a suspended user,</p>
<pre><code>INSERT INTO status_log (userid, status, logcreated) VALUES (1, 's', '2008-01-01');
INSERT INTO status_log (userid, status, logcreated) VALUES (1, 'a', '2008-02-01');

<p>So this user was suspended on 1st Jan and active again on 1st of February.</p>
<p>If I wanted to get a suspended list of customers on 15th January 2008, then userid 1 should show up. If I get a suspended list of customers on 15th February 2008, then userid 1 should not show up.</p>
<p>1) Is this the best way to structure this data for this kind of query?</p>
<p>2) How do I query the data in either this structure or in your proposed modified structure so that I can simply have a date (say 15th January) and find a list of customers that had an active status on that date in SQL only? Is this a job for SQL?</p>

<p>I've never been so good at design because there are so many different possibilities and they all have pros and cons and I'm never sure which to go with. Anyway, here's my problem, I have a need for many different loosly related classes to have validation. However, some of these classes will need extra information to do the validation. I want to have a method <code>validate</code> that can be used to validate a Object and I want to determine if an Object is validatable with an interface, say <code>Validatable</code>. The following are the two basic solutions I can have.</p>
<pre><code>interface Validatable {
public void validate() throws ValidateException;
}
interface Object1Validatable {
public void validate(Object1Converse converse) throws ValidateException;
}
class Object1 implements Object1Validatable {
...
public void validate() throws ValidateException {
throw new UnsupportedOperationException();
}
}
class Object2 implements Validatable {
...
public void validate() throws ValidateException {
...
}
}
</code></pre>
<p>This is the first solution whereby I have a general global interface that something that's validatable implements and I could use <code>validate()</code> to validate, but Object1 doesn't support this so it's kind of defunc, but Object2 does support it and so may many other classes.</p>
<p>Alternatively I could have the following which would leave me without a top level interface.</p>
<pre><code>interface Object1Validatable {
public void validate(Object1Converse converse) throws ValidateException;
}
class Object1 implements Object1Validatable {
...
public void validate(Object1Converse converse) throws ValidateException {
...
}
}
interface Object2Validatable {
public void validate() throws ValidateException;
}
class Object2 implements Object2Validatable {
...
public void validate() throws ValidateException {
...
}
}
</code></pre>
<p>I think the main problem I have is that I'm kind of stuck on the idea of having a top level interface so that I can at least say X or Y Object is validatable.</p>

<p>I'm new to Spring Security. How do I add an event listener which will be called as a user logs in successfully? Also I need to get some kind of unique session ID in this listener which should be available further on. I need this ID to synchronize with another server.</p>

<p>I'm trying to call the SQL statement below but get the following error:</p>
<blockquote>
<p>System.Data.SqlClient.SqlException: Conversion failed when converting
the varchar value '+@buildingIDs+' to data type int.</p>
</blockquote>
<pre><code>@"SELECT id, startDateTime, endDateTime

</code></pre>
<p><code>buildingID</code> is an <code>int</code> type column in the db. Will I need to pass the IDs as an array of ints?</p>

<p>ModRewrite can easily handle stripping the www off the front of my domain.<br>
In .htaccess:</p>
<pre><code>RewriteEngine On
RewriteCond %{HTTPS} on
RewriteCond %{HTTP_HOST} ^www\.(.+)$ [NC]
RewriteRule ^(.*)$ https://%1/$1 [R=301,L]
RewriteCond %{HTTPS} off
RewriteCond %{HTTP_HOST} ^www\.(.+)$ [NC]
RewriteRule ^(.*)$ http://%1/$1 [R=301,L]
</code></pre>
<p>But with SSL, the certificate check comes before the .htaccess rewrite, causing certificate error.<br>
I would rather not buy an SSL certificate for the www only to redirect it.<br>
Can you offer me a smarter solution?
(btw EV Certificates are not available as wildcards)</p>

<p>I have a log file being written by another process which I want to watch for changes. Each time a change occurs I'd like to read the new data in to do some processing on it.</p>
<p>What's the best way to do this? I was hoping there'd be some sort of hook from the PyWin32 library. I've found the <code>win32file.FindNextChangeNotification</code> function but have no idea how to ask it to watch a specific file.</p>
<p>If anyone's done anything like this I'd be really grateful to hear how...</p>
<p><strong>[Edit]</strong> I should have mentioned that I was after a solution that doesn't require polling.</p>
<p><strong>[Edit]</strong> Curses! It seems this doesn't work over a mapped network drive. I'm guessing windows doesn't 'hear' any updates to the file the way it does on a local disk.</p>

<p>I am trying to recreate a Perl script in C# but have a problem creating a checksum value that a target system needs.</p>
<p>In Perl this checksum is calculated using the <code>unpack</code> function:</p>
<pre><code>while (<PACKAGE>) {
$checksum += unpack("%32C*", $_);
}
$checksum %= 32767;
close(PACKAGE);
</code></pre>
<p>where <code>PACKAGE</code> is the .tar file input stream</p>
<p>I need to replicate this in C# but can't find a means of replicating that <code>unpack</code> function.</p>
<p>All help appreciated!</p>
<p>(I know there are much better checksum calculations available but can't change target system so can't change calculation) </p>

<p>I love Python because it comes batteries included, and I use built-in functions, a lot, to do the dirty job for me.</p>
<p>I have always been using happily the os.path module to deal with file path but recently I ended up with unexpected results on Python 2.5 under Ubuntu linux, while dealing with string that represent windows file paths :</p>
<pre><code>filepath = r"c:\ttemp\FILEPA~1.EXE"
print os.path.basename(filepath)
'c:\\ttemp\\FILEPA~1.EXE']
print os.path.splitdrive(filepath)
('', 'c:\ttemp\\FILEPA~1.EXE')
</code></pre>
<p>WTF ?</p>
<p>It ends up the same way with filepath = u"c:\ttemp\FILEPA~1.EXE" and filepath = "c:\ttemp\FILEPA~1.EXE".</p>
<p>Do you have a clue ? Ubuntu use UTF8 but I don't feel like it has something to do with it. Maybe my Python install is messed up but I did not perform any particular tweak on it that I can remember.</p>

<p>Using Oracle, if a column value can be 'YES' or 'NO' is it possible to constrain a table so that only one row can have a 'YES' value?</p>
<p>I would rather redesign the table structure but this is not possible.</p>
<p>[UDPATE] Sadly, null values are not allowed in this table.</p>

<p>I have a template in word (.docx) format and want to replace some placeholders in this template with my own data, do you know where I can find the right classes for this project? It would be nice for me to know the namespace. Are there any newer classes for handling word documents in the docx format (xml) than the com classes? Thank you for all your answers, I hope someone can help me with my problem.</p>

<p>Why can't I pass the table name to a prepared PDO statement?</p>
<pre><code>$stmt = $dbh->prepare('SELECT * FROM :table WHERE 1');
if ($stmt->execute(array(':table' => 'users'))) {
var_dump($stmt->fetchAll());
}
</code></pre>
<p>Is there another safe way to insert a table name into a SQL query? With safe, I mean that I don't want to do</p>
<pre><code>$sql = "SELECT * FROM $table WHERE 1"

<p>I've often heard criticism of the lack of thread safety in the Swing libraries. Yet, I am not sure as to what I would be doing in my own code with could cause issues:</p>
<p>In what situations does the fact Swing is not thread safe come into play ?</p>
<p>What should I actively avoid doing ?</p>

<p>I'm trying to serialize objects from a database that have been retrieved with Hibernate, and I'm only interested in the objects' actual data in its entirety (cycles included).</p>
<p>Now I've been working with <a href="http://xstream.codehaus.org/" rel="nofollow noreferrer">XStream</a>, which seems powerful. The problem with XStream is that it looks all too blindly on the information. It recognizes Hibernate's PersistentCollections as they are, with all the Hibernate metadata included. I don't want to serialize those.</p>
<p>So, is there a reasonable way to extract the original Collection from within a PersistentCollection, and also initialize all referring data the objects might be pointing to. Or can you recommend me to a better approach?</p>
<p>(The results from <a href="http://simple.sourceforge.net/" rel="nofollow noreferrer">Simple</a> seem perfect, but it can't cope with such basic util classes as Calendar. It also accepts only one annotated object at a time)</p>

<p>What is the easiest way to check if events have been logged in the eventlog during a period of time?</p>
<p>I want to perform a series of automated test steps and then check if any errors were logged to the Application Event Log, ignoring a few sources that I'm not interested in. I can use System.Diagnostics.EventLog and then look at the Entries collection, but it doesn't seem very useable for this scenario. For instance Entries.Count can get smaller over time if the event log is removing old entries. I'd prefer some way to either query the log or monitor it for changes during a period of time. e.g. </p>
<pre><code>DateTime start = DateTime.Now;
// do some stuff...
foreach(EventLogEntry entry in CleverSolution.EventLogEntriesSince(start, "Application"))
{
// Now I can do stuff with entry, or ignore if its Source is one
// that I don't care about.
// ...
}
</code></pre>

<p>I am currently creating a custom control that needs to handle animation in a C# project. It is basically a listbox that contains a fixed number of elements that are subject to move. An element (another user control with a background image and a couple of generated labels) can move upwards, downwards or be taken out of the list. </p>
<p>I would like to create animated movement as the elements get moved around within the container custom control but it seems to me that moving controls around using lines such as</p>
<pre><code>myCustomControl.left -= m_iSpeed;</code></pre>
<p>triggered within a timer event is flickery and has a terrible rendering, even with double buffering turned on.</p>
<p>So here's the question : <strong>What is the best way to achieve a flicker-free animated C# control?</strong> Should I just not create custom controls and handle all of the drawing within a panel's background image that I generate? Is there a super animation method that I have not discovered? :)</p>
<p>Thanks!</p>

<p>I've got a column in a database table (SQL Server 2005) that contains data like this:</p>
<pre><code>TQ7394
SZ910284
T r1534
su8472
</code></pre>
<p>I would like to update this column so that the first two characters are uppercase. I would also like to remove any spaces between the first two characters. So <code>T q1234</code> would become <code>TQ1234</code>.</p>
<p><strong>The solution should be able to cope with multiple spaces between the first two characters.</strong></p>
<p>Is this possible in T-SQL? How about in ANSI-92? I'm always interested in seeing how this is done in other db's too, so feel free to post answers for PostgreSQL, MySQL, et al.</p>

<p>In a few large projects i have been working on lately it seems to become increasingly important to choose one or the other (XML or Annotation). As projects grow, consistency is very important for maintainability. </p>
<p>My questions are: what are the advantages of XML-based configuration over Annotation-based configuration and what are the advantages of Annotation-based configuration over XML-based configuration?</p>

<p>Is there a manual for cross-compiling a C++ application from Linux to Windows?</p>
<p>Just that. I would like some information (links, reference, examples...) to guide me to do that.</p>
<p>I don't even know if it's possible. </p>
<p>My objective is to compile a program in Linux and get a .exe file that I can run under Windows.</p>

<p>I have a JavaScript array that, among others, contains a URL. If I try to simply put the URL in the page (the array is in a project involving the Yahoo! Maps API) it shows the URL as it should be.</p>
<p>But if I try to do a redirect or simply do an 'alert' on the link array element I get: </p>
<blockquote>
<p>function(){return JSON.encode(this);}</p>
</blockquote>
<p>As far as I see it this is because the browser does an JSON.encode when it renders the page, thus the link is displayed OK. I have tried several methods to make it redirect (that's what I want to do with the link) correctly (including the usage of 'eval') but with no luck.</p>
<p>After following some suggestions I've run <code>eval('(' + jsonObject + ')')</code> but it still returns the same output.</p>
<p>So how's this done ? </p>

<p>Are there any tools available for validating a database schema against a set of design rules, naming conventions, etc.</p>
<p>I'm not talking about comparing one database to another (as covered by <a href="https://stackoverflow.com/questions/165401/how-to-comparevalidate-sql-schema">this question</a>).</p>
<p>I want to be able to say "What in this database doesn't meet this set of rules". </p>
<p>Some examples of the type of rules I'm talking about would be like:<br>
- Primary key fields should be the first in the table.<br>
- Foreign keys should have an index on that field.<br>
- Field names ending 'xxx' should be of a certain type.<br>
- Fields with a constraint limiting it it certain values it should have a default.</p>
<p>I've written a bunch of scripts to do this in the past and was wondering if there was something generic available.</p>
<p>Ideally I'd like something for SQL Server, but if you're aware of something for other databases it may be useful to know about them too.</p>

<p>This question is a follow-up from <a href="https://stackoverflow.com/questions/161822/how-to-indicate-that-a-method-was-unsuccessful">How to indicate that a method was unsuccessful</a>. The xxx() Tryxxx() pattern is something that can be very useful in many libraries. I am wondering what is the best way to offer both implementations without duplicating my code.</p>
<p>What is best:</p>
<pre><code>public int DoSomething(string a)
{
// might throw an exception
}
public bool TrySomething(string a, out result)
{
try
{
result = DoSomething(a)
return true;
}
catch (Exception)
{
return false;
}
</code></pre>
<p>or</p>
<pre><code>public int DoSomething(string a)
{
int result;
if (TrySomething(a, out result))
{
return result;
}
else
{
throw Exception(); // which exception?
}
}
public bool TrySomething(string a, out result)
{
//...
}
</code></pre>
<p>I'd instinctively assume that the first example is more correct (you know exactly which exception happened), but couldn't the try/catch be too expensive? Is there a way to catch the exception in the second example?</p>

<p>I use <a href="http://xfire.codehaus.org/" rel="nofollow noreferrer">XFire</a> to create a webservice wrapper around my application. XFire provides the webservice interface and WSDL at runtime (or creates them at compile time, don't know exactly).</p>
<p>Many of our customers don't know webservices very well and additionally they simply don't read any external documentation like Javadoc. I know that it's possible to add documentation (for parameters and methods) directly to the WSDL file. </p>
<p>I thought about Annotations or Aegis XML files but I don't know how... Do you know a way?</p>
<p>Edit: I just found this <a href="http://jira.codehaus.org/browse/XFIRE-507" rel="nofollow noreferrer">JIRA issue</a> but the last activity was 2006. Any ideas? </p>

<p>AFAIK, Currency type in Delphi Win32 depends on the processor floating point precision. Because of this I'm having rounding problems when comparing two Currency values, returning different results depending on the machine.</p>
<p>For now I'm using the SameValue function passing a Epsilon parameter = 0.009, because I only need 2 decimal digits precision.</p>
<p>Is there any better way to avoid this problem?</p>

<p>I would like TortoiseSVN (1.5.3) to ignore certain folders, their contents and certain other files wherever they might appear in my directory hierarchy but I cannot get the global ignore string right.</p>
<p>Whatever I do, it either adds to much or ignores too much</p>
<p>What is the correct 'Global ignore pattern' to ignore....</p>
<pre><code>Folders : bin obj release compile
Files : *.bak *.user *.suo
</code></pre>
<p>Update: To help clarify... yes I am using this on windows. </p>

<p>I have to produce an RSS/Atom feed in various applications, and I want to know a good library or class which is able to produce both, and which already handles all common problems.</p>
<p>For example, the one I used for years does not put the right format for date, so my feed is not well-handled by several aggregators.</p>
<p><strong>Update:</strong>
Why I am looking for a library? Because the one I used for years, which I had hacked a few times, has a little problem. Maybe a specification is not being correctly followed.</p>

<p>Ok I give up, I've been trying to write a regexp in ant to replace the version number from something that I have in a properties file. I have the following:</p>
<pre><code><?xml version="1.0" encoding="UTF-8"?>
<feature
id="some.feature.id"
label="Some test feature"
version="1.0.0"
provider-name="Provider">
<plugin
id="test.plugin"
download-size="0"
install-size="0"
version="0.0.0"
unpack="false"/>
..... many plugins later....
</feature>
</code></pre>
<p>What I want to achieve is substitute the version number of the feature tag only, without changing the version of the xml or the version of the miriad of plugins in the file.</p>
<p>The problem I have is that I either match too much or too little. Definitively matching "version" is not enough, because everything would be changed</p>
<p>Is there any easy way to match then only the version inside the tag, taking into consideration that the '0.0.0' could be any number?</p>

<p>Leaving aside the question of whether you should serve single or multiple stylesheets, assuming you're sending just one, what do you think of this as a basic structure?</p>
<p>/* Structure */</p>
<p>Any template layout stuff should be put into here, so header, footer, body etc.</p>
<p>/* Structure End */</p>
<p>/* Common Components*/</p>
<p>Repeated elements, such as signup forms, lists, etc.</p>
<p>/* Common Components End*/</p>
<p>/* Specific Page 1 */</p>
<p>Some pages might have specific styles, that would go here.</p>
<p>/* Specific Page 1 End */</p>
<p>/* Specific Page 2 */</p>
<p>As above</p>
<p>/* Specific Page 2 End */</p>
<p>/* Specific Page etc */</p>
<p>And so on.</p>
<p>/* Specific Page etc End */</p>

<p>I have have some code which adds new cells to a table and fills them with text boxes. </p>
<p>The way I've coded it so far works fine:</p>
<pre><code> TableCell tCell1 = new TableCell();
TableCell tCell2 = new TableCell();
TableCell tCell3 = new TableCell();
TableCell tCell4 = new TableCell();
TableCell tCell5 = new TableCell();
TableCell tCell6 = new TableCell();
TableCell tCell7 = new TableCell();
TextBox txt1 = new TextBox();
TextBox txt2 = new TextBox();
TextBox txt3 = new TextBox();
TextBox txt4 = new TextBox();
TextBox txt5 = new TextBox();
TextBox txt6 = new TextBox();
TextBox txt7 = new TextBox();
tCell1.Controls.Add(txt1);
tCell2.Controls.Add(txt2);
tCell3.Controls.Add(txt3);
tCell4.Controls.Add(txt4);
tCell5.Controls.Add(txt5);
tCell6.Controls.Add(txt6);
tCell7.Controls.Add(txt7);
tRow.Cells.Add(tCell1);
tRow.Cells.Add(tCell2);
tRow.Cells.Add(tCell3);
tRow.Cells.Add(tCell4);
tRow.Cells.Add(tCell5);
tRow.Cells.Add(tCell6);
tRow.Cells.Add(tCell7);
</code></pre>
<p>As you can see there's basically 4 instructions getting repeated 7 times. I'm sure there has to be a way to accomplish this with just 4 lines of code within a FOR loop and having all the names dynamically assigned but I just can't seem to find anything that would point me in the direction of how to do it.</p>
<p>Something like the following is what I'm after:</p>
<pre><code> for (int i = 0; i < 6; i++)
{
TableCell tCell[i] = new TableCell();
TextBox txt[i] = new TextBox();
tCell[i].Controls.Add(txt[i]);
tRow.Cells.Add(tCell[i]);
}
</code></pre>
<p>Any help would be much appreciated.</p>

<p>SQL to find duplicate entries (within a group)</p>
<p>I have a small problem and I'm not sure what would be the best way to fix it, as I only have limited access to the database (Oracle) itself.
In our Table "EVENT" we have about 160k entries, each EVENT has a GROUPID and a normal entry has exactly 5 rows with the same GROUPID. Due to a bug we currently get a couple of duplicate entries (duplicate, so 10 rows instead of 5, just a different EVENTID. This may change, so it's just <> 5). We need to filter all the entries of these groups.</p>
<p>Due to limited access to the database we can not use a temporary table, nor can we add an index to the GROUPID column to make it faster.</p>
<p>We can get the GROUPIDs with this query, but we would need a second query to get the needed data</p>
<pre><code>select A."GROUPID"
from "EVENT" A
group by A."GROUPID"
having count(A."GROUPID") <> 5
</code></pre>
<p>One solution would be a subselect:</p>
<pre><code>select *
from "EVENT" A
where A."GROUPID" IN (
select B."GROUPID"
from "EVENT" B
group by B."GROUPID"
having count(B."GROUPID") <> 5
)
</code></pre>
<p>Without an index on GROUPID and 160k entries, this takes much too long.
Tried thinking about a join that can handle this, but can't find a good solution so far.</p>
<p>Anybody can find a good solution for this maybe?</p>
<p>Small edit:
We don't have 100% duplicates here, as each entry still has a unique ID and the GROUPID is not unique either (that's why we need to use "group by") - or maybe I just miss an easy solution for it :)</p>
<p>Small example about the data (I don't want to delete it, just find it)</p>
<p><code>
EVENTID | GROUPID | TYPEID<br>
123456 123 12<br>
123457 123 145<br>
123458 123 2612<br>
123459 123 41<br>
123460 123 238<br>
<br>
234567 123 12<br>
234568 123 145<br>
234569 123 2612<br>
234570 123 41<br>
234571 123 238<br>
</code><br>
It has some more columns, like timestamp etc, but as you can see already, everything is identical, besides the EVENTID.</p>
<p>We will run it more often for testing, to find the bug and check if it happens again.</p>

<p>Sybase db tables do not have a concept of self updating row numbers. However , for one of the modules , I require the presence of rownumber corresponding to each row in the database such that max(Column) would always tell me the number of rows in the table.</p>
<p>I thought I'll introduce an int column and keep updating this column to keep track of the row number. However I'm having problems in updating this column in case of deletes. What sql should I use in delete trigger to update this column? </p>

<p>We are developing a considerably big application using Ruby on Rails framework (CRM system) and are considering to rewrite it to use ExtJS so that Rails would just do the data handling, while ExtJS would do all the browser heavylifting in a desktop-like manner. </p>
<p>Anyone has some experience and hints about what would be the best approach? Is ExtJS mature enough to be used in relatively big (and complex) applications? And what about the Rails part - what would be the best approach here?</p>
<p>EDIT:</p>
<p>Just to make it clear. I would prefer to do it in such a way that all the javascript client side application code is loaded at once (at the start up of the application, optimally as one compressed js file) and then just use ajax to send data to and from Rails app. Also, it would be nice to have ERB available for dynamic generation of the Ext apliccation elements.</p>

<p>PowerShell v1.0 is obviously a console based administrative shell. It doesn't really require a GUI interface. If one is required, like the Exchange 2007 management GUI, it is built on top of PowerShell. You can create your own GUI using Windows Forms in a PowerShell script. My question is, "What sort of PowerShell scripts or management tasks do you think would be best served with the addition of even a simple graphical interface? What have you created winforms to accomplish?"</p>

<p>Is there a best practice when it comes to setting client side "onclick" events when using ASP.Net controls? Simply adding the onclick attribute results in a Visual Studio warning that onclick is not a valid attribute of that control. Adding it during the Page_Load event through codebehind works, but is less clear than I'd like.</p>
<p>Are these the only two choices? Is there a right way to do this that I'm missing?</p>
<p>Thanks!
Eric Sipple</p>

<p>I have a webapp that segfaults when the database in restarted and it tries to use the old connections. Running it under <code>gdb --args apache -X</code> leads to the following output:</p>
<pre><code>Program received signal SIGSEGV, Segmentation fault.
[Switching to Thread -1212868928 (LWP 16098)]
0xb7471c20 in mysql_send_query () from /usr/lib/libmysqlclient.so.15
</code></pre>
<p>I've checked that the drivers and database are all up to date (<a href="http://search.cpan.org/dist/DBD-mysql/" rel="nofollow noreferrer" title="DBD::mysql">DBD::mysql</a> 4.0008, MySQL 5.0.32-Debian_7etch6-log).</p>
<p>Annoyingly I can't reproduce this with a trivial script:</p>
<pre><code>use DBI;
use Test::More tests => 2;
my $dbh = DBI->connect( "dbi:mysql:test", 'root' );
sub test_db {
my ($number) = $dbh->selectrow_array("select 1 ");
return $number;
}
is test_db, 1, "connected to db";
warn "restart db now";
getc;
is test_db, 1, "connected to db";
</code></pre>
<p>Which gives the following:</p>
<pre><code>ok 1 - connected to db
restart db now at dbd-mysql-test.pl line 23.
DBD::mysql::db selectrow_array failed: MySQL server has gone away at dbd-mysql-test.pl line 17.
not ok 2 - connected to db
# Failed test 'connected to db'
# at dbd-mysql-test.pl line 26.
# got: undef
# expected: '1'
</code></pre>
<p>This behaves correctly, telling me why the request failed.</p>
<p>What stumps me is that it is segfaulting, which it shouldn't do. As it only appears to happen when the whole app is running (which uses <a href="http://search.cpan.org/dist/DBIx-Class" rel="nofollow noreferrer" title="DBIx::Class">DBIx::Class</a>) it is hard to reduce it to a test case.</p>
<p>Where should I start to look to debug this? Has anyone else seen this?</p>
<p><strong>UPDATE</strong>: further prodding showed that it being under mod_perl was a red herring. Having reduced it to a simple test script I've now posted to the <a href="http://www.mail-archive.com/dbi-users@perl.org/msg31416.html" rel="nofollow noreferrer">DBI mailing list</a>. Thanks for your answers.</p>

<p>If you had to iterate through a loop 7 times, would you use:</p>
<pre><code>for (int i = 0; i < 7; i++)
</code></pre>
<p>or:</p>
<pre><code>for (int i = 0; i <= 6; i++)
</code></pre>
<p>There are two considerations:</p>
<ul>
<li>performance</li>
<li>readability </li>
</ul>
<p>For performance I'm assuming Java or C#. Does it matter if "less than" or "less than or equal to" is used? If you have insight for a different language, please indicate which.</p>
<p>For readability I'm assuming 0-based arrays.</p>
<p><strong>UPD:</strong> My mention of 0-based arrays may have confused things. I'm not talking about iterating through array elements. Just a general loop. </p>
<p>There is a good point below about using a constant to which would explain what this magic number is. So if I had "<code>int NUMBER_OF_THINGS = 7</code>" then "<code>i <= NUMBER_OF_THINGS - 1</code>" would look weird, wouldn't it. </p>

<p>When reading my RSS feed with the Thunderbird feed reader, some entries are duplicated. <a href="https://en.wikipedia.org/wiki/Google_Reader" rel="nofollow noreferrer">Google Reader</a> does not have the same problem.</p>
<p>Here is the faulty feed:
<a href="http://plcoder.net/rss.php?rss=Blog" rel="nofollow noreferrer">http://plcoder.net/rss.php?rss=Blog</a></p>
<p>There is a problem, but where?</p>
<p>I added a <a href="https://en.wikipedia.org/wiki/Globally_unique_identifier" rel="nofollow noreferrer">GUID</a>, but the problem remains. Other feeds do not duplicate like mine, so I will do rework on this module and replace this old good code.</p>
<p>Conclusion: I completely reworked the RSS generator code, and it's OK. I think I was using a very old version of <a href="https://en.wikipedia.org/wiki/Resource_Description_Framework" rel="nofollow noreferrer">RDF</a>.</p>

<p>I have an application that seems to throw exceptions only after the program has been closed. And it is very inconsistent. (We all know how fun inconsistent bugs are...)</p>
<p>My guess is there is an error during the clean up process. But these memory read/write errors seem to indicate something wrong in my "unsafe" code usage (pointers?).</p>
<p>What I am interested in is what is the best method to debug these situations?<br>
How do you debug a program that has already closed?<br>
I am looking for a starting point to break down a larger problem.</p>
<p>These errors seem to present themselves in several ways (some run time, some debug):</p>
<pre>
1: .NET-BroadcastEventWindow.2.0.0.0.378734a.0: Application.exe - Application Error<BR>
The instruction at "0x03b4eddb" referenced memory at "0x00000004". The memory could not be "written".
2: Application.vshost.exe - Application Error<br>
The instruction at "0x0450eddb" referenced memory at "0x00000004". The memory could not be "written".
3: Application.vshost.exe - Application Error<br>
The instruction at "0x7c911669" referenced memory at "0x00000000". The memory could not be "read".
4: Application.vshost.exe - Application Error<br>
The instruction at "0x7c910ed4" referenced memory at "0xfffffff8". The memory could not be "read".
</pre>

<p>I'm creating a generic class and in one of the methods I need to know the Class of the generic type currently in use. The reason is that one of the method's I call expects this as an argument.</p>
<p>Example:</p>
<pre><code>public class MyGenericClass<T> {
public void doSomething() {
// Snip...
// Call to a 3rd party lib
T bean = (T)someObject.create(T.class);
// Snip...
}
}
</code></pre>
<p>Clearly the example above doesn't work and results in the following error: Illegal class literal for the type parameter T.</p>
<p>My question is: does someone know a good alternative or workaround for this?</p>

<p>I really don't like the VS2008 Start Page. I don't need the RSS reader, Getting started or Headlines. The only thing useful is "Recent Projects"</p>
<p><strong>Is there a way to customize it or replace with a better one?</strong><br>
It will be nice that the page contains Favorites Projects and Recent projects.</p>
<p>P.S. I know that I can disabled it or replace it with other web page, just looking for a good productivity tip.</p>

<p>Exception Thrown: "System.ComponentModel.ReflectPropertyDescriptor is not marked as Serializable"</p>
<p>Does this mean I missed marking something as serializable myself, or is this something beyond my control?</p>

<p>We use Spring + Hibernate for a Webapp.</p>
<p>This Webapp will be deployed on two unrelated production sites. These two production sites will use the Webapp to generate and use Person data in parallel.</p>
<p>What I need to do, is to make sure that the Persons generated on these two unrelated production sites all have distinct PKs, so that we can merge the Person data from these two sites at any time.</p>
<p>A further constraint imposed to me is that these PKs fit in a <code>Long</code>, so I can't use UUIDs.</p>
<p>What I'm trying to do is to change the current hibernate mapping, that has sequence <code>S_PERSON</code> as generator:</p>
<pre><code><hibernate-mapping default-cascade="save-update" auto-import="false">
<class name="com.some.domain.Person" abstract="true">
<id name="id">
<column name="PERSON_ID"/>
<generator class="sequence">
<param name="sequence">S_PERSON</param>
</generator>
</id>
...
</hibernate-mapping>
</code></pre>
<p>into something configurable, so that <code>PERSON_ID</code> have its PKs generated from different sequences (maybe <code>S_PERSON_1</code> and <code>S_PERSON_2</code>) depending on the deployment site's Spring configuration files.</p>
<p>Of course,</p>
<pre><code> <generator class="sequence">
<param name="sequence">${sequenceName}</param>
</generator>
</code></pre>
<p>doesn't work, so I have to figure out something else... I guess my generator should point to a configurable bean that in turn points to a sequence or another, but I can't figure how to do that...</p>
<p>Any ideas or workaround?</p>
<p>Thanks!</p>

<p>I'm using the wxGlade designer to generate the GUI for a small application.
It generates a class, inherited from wxFrame, which is the main application window.
In order to facilitate the maintenance, I'd like to avoid writing additional code in this generated class.</p>
<p>But all the widgets created with the wxGlade are actually created in the auto-generated method do_layout() and it is not possible to access them outside the scope of that generated method in the generated class.</p>
<p>Is there a way to get pointer of certain widget outside that generated class - by name, by type, by enumerating the children or something like that?</p>

<p>This is a question for anyone who has the pleasure to work in both Java and C#.</p>
<p>Do you find that you have to make a mental context switch of some kind when you move from one to the other?</p>
<p>I'm working in both at the moment and because the syntax and libraries are so similar and yet subtly different I'm finding it frustrating when i move from one to the other.</p>
<p>This is more so than I've experienced moving between any other programming languages.</p>
<p>Does anyone have any tips for making your brain work differently for languages that are so similar?</p>

<p>Suppose some Windows service uses code that wants mapped network drives and no UNC paths. How can I make the drive mapping available to the service's session when the service is started? Logging in as the service user and creating a persistent mapping will not establish the mapping in the context of the actual service.</p>

<p>I'm using Test/Unit with a standard <strong>rails 2.1</strong> project. I would like to be able to test Partial Views in isolation from any particular controller / action.</p>
<p>It seemed as though <a href="http://zentest.rubyforge.org/" rel="noreferrer">ZenTest's Test::Rails::ViewTestCase</a> would help, but I couldn't get it working, similarly with view_test <a href="http://www.continuousthinking.com/tags/view_test" rel="noreferrer">http://www.continuousthinking.com/tags/view_test</a> </p>
<p>Most of the stuff Google turns up seems quite out of date, so I'm guessing doesn't really work with Rails 2.1</p>
<p>Any help with this much appreciated.</p>
<p>Thanks,
Roland</p>

<p>What is the easiest way to test (using reflection), whether given method (i.e. java.lang.Method instance) has a return type, which can be safely casted to List<String>?</p>
<p>Consider this snippet:</p>
<pre><code>public static class StringList extends ArrayList<String> {}
public List<String> method1();
public ArrayList<String> method2();
public StringList method3();
</code></pre>
<p>All methods 1, 2, 3 fulfill the requirement. It's quite easy to test it for the method1 (via getGenericReturnType(), which returns instance of ParameterizedType), but for methods2 and 3, it's not so obvious. I imagine, that by traversing all getGenericSuperclass() and getGenericInterfaces(), we can get quite close, but I don't see, how to match the TypeVariable in List<E> (which occurs somewhere in the superclass interfaces) with the actual type parameter (i.e. where this E is matched to String).</p>
<p>Or maybe is there a completely different (easier) way, which I overlook?</p>
<p><strong>EDIT:</strong> For those looking into it, here is method4, which also fulfills the requirement and which shows some more cases, which have to be investigated:</p>
<pre><code>public interface Parametrized<T extends StringList> {
T method4();
}
</code></pre>

<p>Often, I found OutOfMemoryException on IBM Websphere Application Server.
I think this exception occur because my application retrieve Huge data from database. So, I limit all query don't retreive data more than 1000 records and set JVM of WAS follow</p>
<pre><code>+ Verbose garbage collection
+ Maximum Heap size = 1024 (RAM on my server is 16 GB and now I already change to 8192)
+ Debug arguments = -Djava.compiler=NONE -Xdebug -Xnoagent
-Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=7777
+ Generic JVM arguments = -Dsun.rmi.dgc.server.gcInterval=60000
-Dsun.rmi.dgc.client.gcInterval=60000 -Xdisableexplicitgc
-Dws.log=E:\WebApp\log -Dws.log.level=debug
(ws.log and ws.log.level are my properties)
</code></pre>
<p>And I found <strong>heapdump</strong>, <strong>javacore</strong> and <strong>snap</strong> files in profiles folder I think them can tell me about cause of problem but I don't know how to read/use heapdump, javacore and snap files.</p>
<p>Please tell me how to prevent/avoid/fix OutOfMemoryException.

<p>I have a friend who is need of a web page. He does interior construction, and would like to have a gallery of his work. I'll probably go for a php host, and was thinking about the best way to implement the image gallery for him. I came up with:</p>
<ul>
<li>Use flickr to host the images. They can be tagged, added to sets, and I can use both the tag and set information to display "categories" for the gallery, as well as browsing. Flickr also has multi-upload tools so that a 20 photo job won't be a PITA to upload.</li>
<li>How to best get at the api? Is there a good PHP library for flickr integration? Should I roll my own?</li>
<li>API key - is this considered a commercial project? The web page is for his business, and he will be paying me to create the site...</li>
<li>Is flickr the wrong tool for the job? It seems like a pretty good solution in my head, but is there something I'm missing? I haven't used their APIs at all.</li>
</ul>
<p>Thanks for any input!</p>

<p>I need to determine the highest .NET framework version installed on a desktop machine from C\C++ code. Looks like I can iterate the folders under <code>%systemroot%\Microsoft.NET\Framework</code>, but that seems kind of error prone. Is there a better way? Perhaps a registry key I can inspect? Thanks.</p>

<p>we have a template project we often copy. so we can costumize the copy and still have a common template.<br></p>
<p>To optimize the "copy & initial changes"-process, i though that i can write a little script, that does the following:</p>
<ul>
<li>copy the project-template (in svn) to another directory in the svn</li>
<li>check-out the project and do some changes (change names in some files)</li>
<li>check-in the customized project</li>
</ul>
<p>The question is: what's the best way to do this? any experience in this? which type of script (normal batch or java)? any example code?</p>
<p>thanks for your answers</p>

<p>I've committed changes in numerous files to a SVN repository from Eclipse.</p>
<p>I then go to website directory on the linux box where I want to update these changes from the repository to the directory there.</p>
<p>I want to say "svn update project100" which will update the directories under "project100" with all my added and changed files, etc.</p>
<p>HOWEVER, I don't want to necessarily update changes that I didn't make.
So I thought I could say "svn status project100" but when I do this I get a totally different list of changes that will be made, none of mine are in the list, which is odd.</p>
<p>Hence to be sure that only my changes are updated to the web directory, I am forced to navigate to every directory where I know there is a change that I made and explicitly update only those files, e.g. "svn update newfile1.php" etc. which is tedious.</p>
<p>Can anyone shed any light on the standard working procedure here, namely how do I get an accurate list of all the changes that are about to be made before I execute the "svn update" command? I thought it was the "status" command.</p>

<p>im trying to locate the position of the minimum value in a vector, using STL find algorithm (and the min_element algorithm), but instead of returning the postion, its just giving me the value. E.g, if the minimum value is it, is position will be returned as 8 etc. What am I doing wrong here?</p>
<pre><code>int value = *min_element(v2.begin(), v2.end());
cout << "min value at position " << *find(v2.begin(), v2.end(), value);
</code></pre>

<p>I have parsed XML using both of the following two methods...</p>
<ul>
<li>Parsing the XmlDocument using the object model and XPath queries.</li>
<li>XSL/T</li>
</ul>
<p>But I have never used...</p>
<ul>
<li>The Linq Xml object model that was new to .Net 3.5</li>
</ul>
<p>Can anyone tell me the comparative efficiency between the three alternatives?</p>
<p>I realise that the particular usage would be a factor, but I just want a rough idea. For example, is the Linq option massively slower than the others?</p>

<p>I'd like to create a strongly typed instance of map.ascx in map.cs</p>
<p>Normally, in an aspx, you would add a <%Register... tag to be able to instantiate in codebehind. Is this possible in an app_code class?
I'm using .NET 3.5/Visual Studio 2008</p>

<p>I'm trying to highlight just one specific row in a table using jQuery. The row will have an 'active' status. I have seen plenty of examples online which show how to do zebra striping for alternate row styling. Does anyone know of a jQuery expression which will get a element based on the value of a element in a specific column? </p>

<p>A friend of mine has embedded a google earth plugin into a C# user control. All works fine but when you close the window we recieve and "Unspecified Error" with the option to continue running the scripts or not. From our tracking it down it appears this is being cause by a script that google is dropping onto the page. Any ideas?</p>

<p>I want to compare the current value of an in-memory Hibernate entity with the value in the database:</p>
<pre><code>HibernateSession sess = HibernateSessionFactory.getSession();
MyEntity newEntity = (MyEntity)sess.load(MyEntity.class, id);
newEntity.setProperty("new value");
MyEntity oldEntity = (MyEntity)sess.load(MyEntity.class, id);
// CODEBLOCK#1 evaluate differences between newEntity and oldEntity
sess.update(newEntity);
</code></pre>
<p>In <strong>CODEBLOCK#1</strong> I get that <code>newEntity.getProperty()="new value"</code> AND <code>oldEntity.getProperty()="new value"</code> (while I expected <code>oldEntity.getProperty()="old value"</code>, of course). In fact the two objects are exactly the same in memory.</p>
<p>I messed around with <code>HibernateSessionFactory.getSession().evict(newEntity)</code> and attempted to set <code>oldEntity=null</code> to get rid of it (I need it only for the comparison):</p>
<pre><code>HibernateSession sess = HibernateSessionFactory.getSession();
MyEntity newEntity = (MyEntity)sess.load(MyEntity.class, id);
newEntity.setProperty("new value");
HibernateSessionFactory.getSession().evict(newEntity);
MyEntity oldEntity = (MyEntity)sess.load(MyEntity.class, id);
// CODEBLOCK#1 evaluate differences between newEntity and oldEntity
oldEntity = null;
sess.update(newEntity);
</code></pre>
<p>and now the two entities are distinct, but of course I get the dreaded <code>org.hibernate.NonUniqueObjectException: a different object with the same identifier value was already associated with the session</code>.</p>
<p>Any idea?</p>
<p><strong>EDIT:</strong> I tried the double session strategy; I modified my <code>HibernateSessionFactory</code> to implement a map of session and then...</p>
<pre><code>Session session1 = HibernateSessionFactory.getSession(SessionKeys.DEFAULT);
Session session2 = HibernateSessionFactory.getSession(SessionKeys.ALTERNATE);
Entity newEntity = (Entity)entity;
newEntity.setNote("edited note");
Entity oldEntity = (Entity)session1.load(Entity.class, id);
System.out.println("NEW:" + newEntity.getNote());
System.out.println("OLD: " + oldEntity.getNote()); // HANGS HERE!!!
HibernateSessionFactory.closeSession(SessionKeys.ALTERNATE);
</code></pre>
<p>My unit test hangs while attempting to print the oldEntity note... :-(</p>

<p>I'm making a report in Access 2003 that contains a sub report of related records. Within the sub report, I want the top two records only. When I add "TOP 2" to the sub report's query, it seems to select the top two records before it filters on the link fields. How do I get the top two records of only those records that apply to the corresponding link field? Thanks.</p>

<p>When i deploy a rails application in production mode, it appends a date-time string as a query param to the end of all the static asset urls. This is to prevent browsers using old-out of date cahed copies of the assets after I redeploy the application. </p>
<p>Is there a way to make rails use the old time stamps for the assets that have not changed (and <strong>only</strong> the ones that have not changed) since the last deployment. I want to do this to prevent users having to redownload those assets that have not changed.</p>

<p>Looking into System.Data.DbType there is no SqlVariant type there. SqlDataReader, for example, provides the GetString method for reading into string variable. What is the appropriate way to retrieve data from the database field of type sql_variant, presumably into object? </p>
<p>The aim is to read data stored as <a href="http://msdn.microsoft.com/en-us/library/ms173829.aspx" rel="nofollow noreferrer">sql_variant type</a> in database. Not to assign the value into variable of object type. I mentioned object type variable because I thing the sql_variant, if possible, would go into such type.</p>

<p>This is really two questions, but they are so similar, and to keep it simple, I figured I'd just roll them together:</p>
<ul>
<li><p><strong>Firstly</strong>: Given an established C# project, what are some decent ways to speed it up beyond just plain in-code optimization?</p></li>
<li><p><strong>Secondly</strong>: When writing a program from scratch in C#, what are some good ways to greatly improve performance?</p></li>
</ul>
<p><strong>Please stay away from general optimization techniques unless they are <em>C# specific</em>.</strong></p>
<p>This has previously been asked for <a href="https://stackoverflow.com/questions/172720/speeding-up-python">Python</a>, <a href="https://stackoverflow.com/questions/177122/speeding-up-perl">Perl</a>, and <a href="https://stackoverflow.com/questions/179745/speeding-up-java">Java</a>.</p>

<p>I have a strange bug with WPF Interop and an Excel Addin. I'm using .Net 3.5 SP1.</p>
<p>I'm using Add-in Express to create a Custom Task Pane for Excel 2003. Within that taskpane I'm using ElementHost to host a WPF UserControl. The UserControl simply contains a Grid with a TextBox and ComboBox. My problem is that whilst everything displays properly, the ComboBox won't stay dropped-down unless I hold the mouse down over the down-arrow.</p>
<p>I don't believe this is necessarily related to Add-in Express because I've had a similar problem when I tried displaying a WPF window modelessly in Excel.</p>
<p>A second problem is that the ComboBox seems reluctant to give up focus. If I click it, the text area goes grey to indicate that it has focus, but I can't move focus anywhere else in the window. The only way to wrest focus away is to move the mousewheel.</p>
<p>Anybody else had a similar problem, and managed to fix it?</p>

<p>How does one go about establishing a CSS 'schema', or hierarchy, of general element styles, nested element styles, and classed element styles. For a rank novice like me, the amount of information in stylesheets I view is completely overwhelming. What process does one follow in creating a well factored stylesheet or sheets, compared to inline style attributes?</p>

<p>My normal IDE is Visual Studio, but I'm currently doing some development in Eclipse for the first time. If you press Ctrl-X with text selected in either program, it cuts the text and puts on the clipboard exactly as you'd expect. If press Ctrl-X with no text selected in Visual Studio, it cuts the current line. In Eclipse it is ignored. Is there a way to get Eclipse to use Studio's behavior?</p>

<p>I have data loaded and various transformations on the data complete, the problem is there is a parent/child relationship managed in the data - best explained by an example</p>
<p>each row has (column names are made up)</p>
<pre><code>row_key parent_row_key row_name parent_row_name
</code></pre>
<p>some rows have row_key == parent_row_key (their own parent)
some rows relate to another row
(row 25 is the parent to row 44 for example).</p>
<p>In this case, row 25 is parent to row 44. I need to put row 25's row_name in row 44's parent_row_name. How do I query the data in the pipeline for the value?</p>

<p>I would like to add a BuildListener to my headless build process, which is building an Eclipse product. The docs on how to do this are, shall we say, a bit scanty. I think I need to put my custom jar in a plugin and then use the org.eclipse.ant.core.extraClasspathEntries extension point to make that jar visible to Ant. But everything I have tried results in <pre> [myClass] which was specified to be a build listener is not an instance of org.apache.tools.ant.BuildListener.</pre></p>
<p>My class implements the BuildListener interface. Various postings seem to indicate that this means my class is visible-to/loaded-by the Plugin classloader rather than the Ant classloader. But I thought the whole point of the extension point was to make jars visible to Ant...</p>
<p>Can anyone shed light on what I'm doing wrong?
Additional info: I am trying to run this build from the Eclipse IDE at the moment using the AntRunner application.</p>

<p>I'm looking for ideas and opinions here, not a "real answer", I guess...</p>
<p>Back in the old VB6 days, there was this property called "Tag" in all controls, that was a useful way to store custom information related to a control. Every single control had it, and all was bliss...</p>
<p>Now, in .Net (at least for WebForms), it's not there anymore...</p>
<p>Does anyone have a good replacement for that?</p>
<p>I find this problem very often, where I have different functions that run at different times in the lifecycle, and they do stuff with my controls, and I want to keep them as separate as they are, but one should pass information to the other about specific controls.</p>
<p>I can think of a million alternatives (starting with a module-level dictionary, obviously), but none as clean as the good ol' Tag.</p>
<p>(NOTE: I know I can subclass ALL the controls and use my version instead. I'd rather not)</p>
<p>Any suggestions?
How do you solve this normally?
Any ideas on why they removed this i the first place?</p>
<p>EDIT: I'm looking for something Intra-Request, not Inter-Request. I don't need this information to still be there on a PostBack. This is between the _Load and the _PreRender methods, for example.</p>
<p>EDIT2: I DO know my ASp.Net and I do know the difference between the desktop and the web, guys!. I 'm just trying to use the abstraction that .Net gives me to the maximum. I understand the tradeoffs, believe me, and please answer assuming that I do.</p>

<p>I use the MFC list control in report view with grid lines to display data in a vaguely spreadsheet manner.</p>
<p>Sometimes when the user scrolls vertically through the control, extra grid lines are drawn, which looks terrible.</p>
<p>This does not happen when the slider or the mousewheel are used to scroll, only when the little down arrow button at the bottom of the scroll control is used.</p>
<p>It seems that this occurs when the size of the list control window is not an exact even number of rows, so that a partial row is visible at the bottom.</p>
<p>If I adjust the size of the list control so that there is no partial rows visible, the problem is solved. However, it will appear when the program is run on another computer, presumably because the number of pixels occupied by a row changes. </p>
<p>I am assuming that it is an interaction between screen resolution, font size and "dialog units".</p>
<p>I guess that I need to programmatically force the size of the control when it is created. But what size?</p>
<p>I have tried using the ApproximateViewRect() method but I cannot get it to work. Perhaps this method does not know about report view?</p>
<p>The other method, I suppose, would be to create my own specialization of CListCtrl and over-ride whatever method is doing the scrolling. This seems likely to be a lot of work.</p>
<p>This screenshot shows a closely related problem where the grid lines go missing</p>
<p><img src="https://i.stack.imgur.com/K5XzV.jpg" alt="alt text"></p>
<p>and here is one with the extra grid lines</p>
<p><img src="https://i.stack.imgur.com/6pADr.jpg" alt="alt text"></p>
<p>The only difference between these two and between them and one which scrolls perfectly is a few pixels different in the vertical size of the control.</p>

<p>I have a C++ template class that gets instantiated with 3 different type parameters. There's a method that the class needs to have for only one of those types and that isn't ever called with the two other types.</p>
<p>Will object code for that method be generated thrice (for all types for which the template is instantiated), or is object code generated only once (for the type with which it is actually used)?</p>
