• Smart Device Development Radio Buttons

  Hi, I have this problem: In my application i have a dataset with some rows, and for each row i design some labels and a textbox and 2 radio buttons dinamically, so my problem is that for example if i have 4 lines (8 radio buttons) i only can have 1 radio button selected. I want to have 1 radio button selected by line, does anyone know how can i do this Thanks. Thanks for your feedback. I already solved the problem with checkboxs (with the same behaviour of radiobuttons). Note: My application is running on a PDA with a resolution of 640x480. ...Show All

• .NET Development Asynchronous Web services in Vs. 2005???

  So I've seen a lot of examples on how to do web services in 2003 but it apears that in 2005 there is no BeginXXX and endXXX so I'm a little lost. So far I have got this which compiles and runs but doesn't seem to catch the result like it should.

• Visual Studio Tools for Office Is there any wait to find when text/bookmark is modified in Word?

  Is there any way to find out when bookmark is added/deleted from "Word Template" addin If it it's not possible, is it possible to find out when anything is modified in Document In this case I can go trough all bookmarks and figure out which ones have been added/deleted So far I found only SelectionChanged event on Document, but it doesn't fire if you're typing, adding/deleting bookmark or hit "Backspace" or "Delete". Thanks, Victor Tools.Word Bookmarks is only available when using VSTO 2005 (not SE). Apparently you're not, since you don't see "Tools"... In this case, you can't use them. The VBA approach means you need to have VBA procedures named the same a ...Show All

• Smart Device Development launching external application on device from c#

• Visual Studio Express Editions How to Delete a File using VBX2005

  I have a problem on my program, In VB 6 I used "Kill" to delete a file that was previously from a picture box. When I used VBX 2005, i got an error, i cannot delete the file that i previously loaded in a picture box, it says "The file is being used by another application" Can u help me please:( I guessed that calling Dispose() would remove the lock but ran into lots of trouble making that work. This finally worked for me: Dim bmp1 As New Bitmap("c:\temp\test.bmp") Dim bmp2 As New Bitmap(bmp1) PictureBox1.Image = bmp2 bmp1.Dispose() Kill("c:\temp\test.bmp") Looks to me like Microsoft is forgetting to call Close or Dispose on their internal stream o ...Show All

• SQL Server Ole DB Destination - Fast Load - Permissions

  All, If I use an OLE DB Destination with Fast Load, and enable check constraints, I would expect to see this work as BCP would in this scenario on 2005. However, instead, I get the error ALTER TABLE permissions required. I understand that when using BCP, if you disable check constraints and triggers, then you need alter permissions. But, when you explicitly enable these, then you do not need this permission. I would expect the same behaviour in SSIS, but I am not seeing it. Fast Load seems to always require ALTER TABLE permissions. Can anyone confirm/deny this Thanks, dcb99 I have a table where I have a simple constraint of having the value of a column less than a certain value. I can use da ...Show All

• Software Development for Windows Vista State Machine Exception Handling

  Can anyone tell me what the best practice is to handle exceptions in a state machine process. I would like to move the instance to different error states depending on the type of exception. It would seem that normal compensation processing is not available in a State Machine Regards Jaco I suggest that you create a simple state machine workflow. In the event driven activity throw an exception and debug the fault handler. This will allow you to step into the process and evaluate the result. I have had some issues with regards to catch and rethrow, but in most cases the out-of-the-box functionality works as advertised Regards Jaco ...Show All
