• .NET Development newly added record not available without debug restart

  I have code that saves a record using a stored procedure.  The sproc passes back the identity to the code, and from there I fill the table adapter with the newly added record, which in turn populates the form with the newly added record. Here is an (abridged) example: void saveChecklist() { try { string CommandText; if ( this .txtEQUIPMENT_ID.Text.Length > 0) { CommandText = "DS_UPDATE_CHECKLIST" ; } else { CommandText = "DS_ADD_CHECKLIST" ; } connectionEquipment conn = new connectionEquipment (); string connectionString = conn.getConnectionString( "equipment" ).ToString(); SqlCo ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. DirectInput and Mouse Acceleration

  I am using the Managed Direct Input library to gather mouse input for a graphical research app.  However, my testing shows that the application is affected by mouse acceleration despite using the Direct Input API. My understanding was that only driver level acceleration could affect the Direct Input data, but if I test some of the samples that ship with the DirectX SDK I don't see the same problem.  The documentation is weak on this topic.  However, there seems to be a knowledge base out there amongst developers.  Does anyone have any ideas I can try.  The applicaitio ...Show All

• Visual Basic SetPixel() - URGENT!

  Hi, I am loading an 8-bpp (bit per pixel) bitmap from a file and trying to set various pixels using the SetPixel method, but no matter what I do (I also tried locking the bits), i get an InvalidOperationException - "SetPixel is not supported for images with indexed pixel formats." After some research i understand that it's not possible to use the SetPixel method in the normal way or possibly not at all for *indexed* bitmaps. If someone could please tell me how to get around this, either somehow using LockBits, or if it really need be, how to convert the bitmap to a non-indexed format in order to use SetPixel(). Thanks in advan ...Show All

• Windows Forms Doubleclick event on combox doesn't trigger

  I added a doubleClick event to a textbox. This is triggered very well. Now i added a MouseDoubleClick event to a combobox (because a doubleclick event doesn't exists apparantly), but this event is not triggered. Why How do i solve this Kind regards Damiaan Peeters Thanks for the hint from Davecat. Double click is quite useful when combobox displayed in DropDownStyleSimple. In a similar fashion in Visual Basic Dim mylastClick As Date = Now Private Sub ComboBoxPathologyTests_MouseClick( ByVal sender As System.Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles ComboBoxPathologyTests.MouseClick ...Show All

  We just hit the following error with SQL 2005 RTM version Msg 8630, Level 17, State 99, Line 18 Internal Query Processor Error: The query processor encountered an unexpected error during execution. Any idea of what that message could mean The only explanation I found in some forums was that this means we had come upon a SQL Server bug The query is actually the EXEC of the below stored proc.

• SQL Server Remote Connection

  Could someone tell me how to remote connect to other server . Everytime when I try to connect to other server, I get an error message . Eventhough I have opened the 1433 port, allow the remote connection using both TCP/IP and named pipes, and open the firewall for connection.

• Visual C++ Lost my Toolbox! / VC++ 6.0

  I'm using a VC++ 6.0 complier and a bit of a software problem.  I've lost my toolbox toolbar!  The one with all the buttons you click and drop controls onto your applications.  I don't know what I did to make it disappear because I have been using other programing tools and haven't used VC++ in about 3 days.  But I've tried clicking on every button and drop down menu and had no luck.  I know this is probably something simple, but could someone offer some advice. EDIT: Ok, I had posted this 24 hours ago and never got a reply.  I finally just had to uninstall my compilier and re-install it to solve my problem.&n ...Show All
