I got a strange symptom with my VB.NET. It says: “Error 1 The item “xxx” was specified more than once in the “Resources” parameter.  Duplicate items are not supported by the “Resources” parameter. It was occured when I try to change the layout of my ‘xxx’ form.

It seems something to do with Form Designer method that was created by VS. I got this thing works up with me.

1. Remove the ‘xxx’ form from recent solution
2. Recompile the project
3. Save the solution
4. Restart the solution
5. Add the ‘xxx’ form
6. Recompile

This should do things. ^^v
Have a nice try
