Are you converting a Windows Forms Application from 2003 to 2005?
I have an application that I started writing in 2003 and wanted to convert to 2005. When you open the project in the 2005 IDE, it converts it for you. However, this conversion left a lot to be desired for me. Granted, the application will still work. But when you add a new control to a form, it isn't smart enough to place it into the "Windows Forms designer generated code" region. It just places the declaration at the top of the form file, which I thought was sloppy. There were other things I did not like, hence this posting.
In a true 2005 application, each form has a .Designer.vb file that accompanies it. This file includes most of the information from the 2003 "Windows Forms designer generated code" region, plus some other things.
The attached VB.NET 2005 project (Conversion Assistant) will allow you to point to a solution and further process the conversion done by the 2005 IDE. Conversion Assistant adds the necessary information into the .vbproj files, changes the form files accordingly and also creates the .Designer.vb files with the correct information for you.
NOTE: You must convert the application using the 2005 IDE first, then run Conversion Assistant.
Warning: I have tested this application on the solutions that I have at hand, which is by no means a complete range of the possibilities. As always, make a backup of your solution files before attempting to convert it. You now have the source code, so if it doesn't work perfectly for you in your scenario, you can modify the source code as needed.
