• C#: Deal with xml, treeview datagridview and datatables

  - by renulren

  Hi all, I am working on a project that pulls data out of an xml files and also uses a tree-grid combination in order to display the data. For example depending on the selected treeview node, the datagridview will display only the records related to that node. What do you think it would be the appropriate approach in dealing with this? Thanks!

• Can I update window.location.hash without having the web page scroll?

  - by Jonathon Watney

  Using JavaScript, is there a way to update window.location.hash without scrolling the web page? I have clickable title elements that toggle the visibility of a div directly beneath them. I want the /foo#bar in the history when clicking titles but don't want the page scrolling about. So when navigating away from /foo#bar I'll be able to use the back button and have the div whose ID is in window.location.hash be visible upon return. Is this behavior possible?

• How to use SetTextCharacterExtra in TEdit or TMemo?

  - by lyborko

  Hi, Does anybody know any component based on TEdit or TMemo, in which is possible to set different intercharacter spacing? Win API SetTextCharacterExtra solves the problem for Tcanvas, but I tried hard to implement this behavior as a property for my own TEdit Component (a year ago) and despite of my various desperate attempts to do this, I failed. Thanx in advance.

• If I never ever use HashSet, should I still implement GetHashCode?

  - by Dimitri C.

  I never need to store objects in a hash table. The reason is twofold: coming up with a good hash function is difficult and error prone. an AVL tree is almost always fast enough, and it merely requires a strict order predicate, which is much easier to implement. The Equals() operation on the other hand is a very frequently used function. Therefore I wonder whether it is necessary to implement GetHashCode (which I never need) when implementing the Equals function (which I often need)?

• Anchor Window to Screen Edges in WPF

  - by Kirk

  I've decided to teach myself C# by writing a music player in Visual Studio 2010. I went with WPF because from what I hear it sounds like it will be a good base to skin from. I want to program my window with the behavior where if the window comes to the edge of a screen (within 10px or so) it will snap to the screen edge. What's the best way to go about this?

• ExtJS: Add Single Click Action To A Node In A TreePanel

  - by FluidFoundation

  [revised] I'm creating a TreePanel in ExtJs that is loading its children from a JSON file. I'm having trouble adding a click action to the nodes. I'm not sure whether it's added in the script creating the tree, or if its added as a property in the JSON, and if so, what the syntax would be. Any help would be appreciated! Please provide an example if possible.

• Stored Procedure could not be found

  - by Beatles1692

  We use SQL server 2008 as our RDBMS and we have a database that has a different user rather than dbo as its owner. The problem is in one machine a stored procedure can not run unless its owner is mentioned. If we connect to our database using this user and try to execute the following : exec ourSP we get a "could not find ourSP" error but this works fine: exec user.ourSP Does anybody knows what can lead to such a strange behavior?

  - by JAre

  I can't run Content Shell on my system (Windows 7 x64): When i run --dump-render-tree with the stable release content_shell.exe crashes with message: [XXXX:XXXX:0522/XXXXXX:XXXXXXXXX:FATAL:content_main_runner.cc(735)] Check failed: base::i18n::InitializeICU() were X - some number.

• How do I declare a constructor for an 'object' class type in Scala? I.e., a one time operation for the singleton.

  - by Zack

  I know that objects are treated pretty much like singletons in scala. However, I have been unable to find an elegant way to specify default behavior on initial instantiation. I can accomplish this by just putting code into the body of the object declaration but this seems overly hacky. Using an apply doesn't really work because it can be called multiple times and doesn't really make sense for this use case. Any ideas on how to do this?

• Are there IDEs in which the code-completion widget is not a linear list?

  - by Uri

  Most mainstream IDEs use code-completion in the form of a linear list of suggestions (typically methods). Are there any IDEs (mainstream or not) or IDE plugins that use a non-linear widget, such as a tree? (e.g., pick category first, then the actual recommendation)? I'm working on an IDE feature and want to make sure I'm not reinventing the wheel or infringing some patent.

• Indexing over the results returned by selenium

  - by Guy

  Hi I try to index over results returned by an xpath. For example: xpath = '//a[@id="someID"]' can return a few results. I want to get a list of them. I thought that doing: numOfResults = sel.get_xpath_count(xpath) l = [] for i in range(1,numOfResults+1): l.append(sel.get_text('(%s)[%d]'%(xpath, i))) would work because doing something similar with firefox's Xpath checker works: (//a[@id='someID'])[2] returns the 2nd result. Ideas why the behavior would be different and how to do such a thing with selenium Thanks

• CopyFileEx and 8.3 file names

  - by Lobuno

  Suppose you have 2 files in the same directory: New File Name.txt and NewFil~1.txt If you use CopyFileEx to copy both files to the same destination, maintaining the same names, you will end up having only ONE file (the second one replaces the first one) which can be sometimes not a good thing. Any workaround for this behavior?

• find: What's up with basename and dirname?

  - by temp2290

  I'm using find for a task and I noticed that when I do something like this: find `pwd` -name "file.ext" -exec echo $(dirname {}) \; it will give you dots only for each match. When you s/dirname/basename in that command you get the full pathnames. Am I screwing something up here or is this expected behavior? I'm used to basename giving you the name of the file (in this case "file.ext") and dirname giving you the rest of the path.

• tomcat startup.sh trouble finding JAVA_HOME

  - by peter

  I am a bit puzzled by this strange behavior on CentOs 5.4 when starting Tomcat 6.0 as a service I've added a script at /etc/init.d/tomcat that can start/stop/restart Apache Tomcat 6.0 with user 'tomcat', and registered it as service. The problem with the service is that I am getting a 'Neither the JAVA_HOME nor the JRE_HOME environment variable is defined'. But when type 'sudo -u tomcat echo $JAVA_HOME' I get '/usr/java/jdk1.5.0_22' which is correct since I am using that JDK. What can I do about this?

• As a programmer, what are some telltale signs that you're about to get fired or laid off?

  - by plaureano

  If you have ever been fired from a job, did you notice anything different about the behavior of your peers or upper management just before your termination? What are some common signs to look for among your coworkers and project manager(s) that would indicate your position is severely at risk? EDIT: My instincts were right, and I opted to resign rather than face termination. I guess when you have that "gut feeling" that something is about to happen, it's a strong sign that you should be heading for the exit...

• Prevent Apache from chunking gzipped content

  - by Bear

  When using mod_deflate in Apache2, Apache will chunk gzipped content, setting the Transfer-encoding: chunked header. While this results in a faster download time, I cannot display a progress bar. If I handle the compression myself in PHP, I can gzip it completely first and set the Content-length header, so that I can display a progress bar to the user. Is there any way to change Apache's behavior, and have Apache set a Content-length header instead of chunking the response, so that I don't have to handle the compression myself?

• How to avoid that the Parameter Pane Area in Drill-Through Report is hidden

  I have a report that via a text box property action triggers a drill-through report (and gives it two parameters (start date, end date)). That all works fine in the report designer, however after deploying the report on the server the pane in the drill-through reports is hidden. Is there a way I can change this behavior. Our users want the pane to be visible in the drill-through report.
