\"There is no editor available for \'C:\\Documents and Settings\\Steven\\Local Settings\\Application Data\\Temporary Projects\\WindowsApplication1\\Form1.vb\'
Make sure the applicaion for the file type (.vb) is installed\"
This error can occur after you have been successfully using VB, and go to open a form in the Forms Designer. There may be many things causing this error, however the fix that worked for me was to reset the settings.
