• Windows Forms Tab Key is not tapped!

  Why doesn't my code work The code is in the KeyPressed event of my textbox - If e.KeyChar = ControlChars.Tab Then messagebox.show ("Tab key was pressed!") end if Regards! Kapalic But, unless VB handles these events differently than C# (and I doubt that this is the case), you should not have been able to trap the Tab key in either one of those events unless you also overrode either the ProcessCmdKey or the IsInputKey method(s) in your TextBox's parent class. Can you verify this is the case I'm mainly interested in learning whether VB handles it differently than C# (since I don't even have VB installed, I can't test this for myself). ...Show All

• Visual C# Misterious crash due to Listview, Bitmap & TabControl usage.

  Greetings, My application crashes misteriously when i access a tabpage that contains a ListView displaying thubmnails images. (See stack trace below) The exception agent displays the following message with an association line connecting it with the " Application .Run( new Form1 ()); " of my "main" routine:  "Parameter is not valid." It will only crash if, before i access the tabpage, the application's window is maximized. The listview is populated in the Form's constructor function. It uses the following simplified code: private void createThumbnails() { ThumbnailCreator t = new ThumbnailCreator (); Bitmap thumb = null ; thumb = t.GetThumbNail( "D:\\Documents and Settings\\T062948\\Des ...Show All

• Visual Basic How to create an installer

  Hello all, I have created a Visual Basic .NET 2003 .exe. I thought I could simply put it on another computer, and it would run. That didn't work. I believe I have to write an installer and include the dll files, as well. Do I have to write an installer, or can I simply put the .exe and the dlls on the other computer If I have to write an installer, would you please let me know how to get started and where I can find info. on how to do this Thanks, Kathy Hi Diango, I'm guessing that you must have missed a step in creating the "My Notepad" project. Try this - add a new Windows Application project to your solution (File, Add, New Project), then go to the FileSystem Editor and try the Add Project ...Show All

• SQL Server Msg 8621: The query processor ran out of stack space during query optimization

  I got the above error when I tried to execute the following query delete from BUSINESS_ASSOCIATE where ba_name is null As you can see the query isn't exactly complicated. What the table does have is lots of dependancies. I got SSMS to show me all the dependancies and there are literally hundreds (maybe thousands - I'm not going to count them all) of dependant tables and i suspect that is what is causing the problem. So what do I do about it This is a valid data-model (industry standard in fact) but SQL won't let me delete data from this table and that's a huge problem for me. Any advice about how to progress would be welcomed. -Jamie It looks like you hit the documented limit on the maxi ...Show All

• Windows Forms Generic Bootstrapper - SQL Express Named Instance

  I'm using the bootstrapper to install a named instance of SQL Express as a prerequisite. If SQL Express is installed on the computer but my instance isn't, the bootstrapper will bypass the installation of my named instance. 1. Is there a way of passing an argument to the SqlExpressChk.exe to look for the named instance instead of any SQL Express installation 2. Is there a better way of accomplishing my installation goal Thanks, Wayne Hi Doppalapudi, I got round my problem in the end by changing the product.xml and package.xml files in the bootsrapper. Firstly I checked whether my instance was installed by doing a registry check in the product.xml: < RegistryCheck Property ="SQLVersio ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Collision detection - Howto

  Hi all, I'm trying to make two objects collide in GSE, actually in a Pong game - between the bat and the ball. I have motion for both, but no collision, the ball just leaves the stage so to speak.

• .NET Development Detecting remove lock event on file

  I have the following problem: We have to write an application that acts on changes on files. For example editing a word - file. We achieve this using the FileSystemWatcher from .NET 2.0.  When the word-file is saved the events correctly trigger, but the files are locked, which causes our action to fail, but this is not the problem. But when the user closes the word-application. The application release the lock,but  we can't seem to catch this event so we could run our actions then.   Does anybody has as solution Thx, gert Windows doesn't provide any way to either detect a lock or be notified that a lock may have been released. To avoid a lot of threads, use just one t ...Show All

• .NET Development Question about DataTable Constraints

  It seems the only constraints you can add to a DataTable are UniqueConstraints and ForeignKeyConstraints. I would like to see a CheckConstraint such as column value < x or > 0 or <> 0…. Is this possible with DataTables Thanks. At the moment I'm trying to get away from the DataTable RowChanged and ColumnChanged events because they fire so often. If I act on those events and change the row/column these events fire again and because I'm listening to the event, I will validate the value I just set in a column or row. Perhaps there's a way to just raise an error on validation. I'll have to look into this yet.... ...Show All

• Visual C++ dll search order

  I hope this is a resonable forum in which to post this question... I ran a Visual C++ program that reported a missing DLL (MFC70D.dll). I located the DLL on another machine and copied it into the same directory where the application program resides. I then ran the program again. It appears to now locate the previously missing dll. But it now reports a different missing DLL (MSVCR70D.dll). I located that one an copied it into the application directory. But when I run the app it still says it can't find it. Shouldn't it have found it Doesn't the search path for DLLs start in the same directory as the ryunning application What is the solution to my problem Roger Garrett Anyway!

This is done in procedural code like this: private void OnRunMyAnim(object sender, RoutedEventArgs args) { Storyboard sb = FindResource("theStoryboard") as Storyboard; sb.Begin(sender as FrameworkElement, HandoffBehavior.SnapshotAndReplace); } The storyboard itself is defined as a resource with a CurrentStateInvalidated handler: <Storyboard x:Key="theStoryboard" CurrentStateInvalidated="OnAnimStateChanged"> Here's my question: In the handler, a ClockGroup is passed in.
