• Windows Forms Icon for my Program

  Hi there, how can I set an Icon for my Program I know how to put an Icon on the form, but not how to set an Icon i can see on the desktop (or where ever the *.exe is). Thanks, Finch. Hi, look at this with the command line compiler, it should be possible to pass these arguments to the compiler in shardevelop, I hope. Otherwise you must use the csc.exe. Working with Resources Using csc.exe The next order of business is to examine how csc.exe can be used to embed resources (such as string tables or image files) into .NET assemblies. First up, the /win32Icon option can be used to specify the path to a Win3 ...Show All

• Visual Studio Tools for Office Word application with cached data

  I'm developing a word application with cached data. The application can modify the data with the cached attribute. When I save the document the data seems to be updated, but if i close and reopen the document I got an old version of the cached data. For example I create a VSTO Word Project with a string with the cached attribute. In the Startup event I save the document and in the BeforeSave event I increment the data and show it.

• Visual Basic control arrays

  I have a project I converted from vb 6.0 which used a textbox control array.  This converted very nicely and the code worked exactly as it had in vb 6.  I need to add 5 textboxes or elements to the array so I copied one of the existing textboxes and cloned it, I hoped.  Didn't work.  The new textboxes are identical except for a property named "Index on Value", which contains the index value.  The old textbox has it and the new ones don't.  Does anyone know of a way I cad add this property to the new textboxes   It would be so much easier than redoing the whole textbox structure. Thanks, Dick ...Show All

  We are currently working on WWF for for a prospect. Wanted to understand the scheme better: on windows 2003 (sp1) will Windows Workflow Foundation Visual Studio extensions cost anything, of course assuming that VS.net or VSTS license is already in place. Since it comes free with vista we have our doubts if its free with Win2k3 with VS. Thanks, -Phani that should require the same license (for the runtime components) on a valid/licensed copy of windows. There is not a licensing fee for using the designer in your application outside of that as far as I know. Matt ...Show All
