I'm working on a major project. I was about to make some large changes that I was unsure of how it would affect the program. So I made a backup of the entire project into a "TestClient" folder, and started my changes. After doing so, one of my forms now report:
There is no editor available for [file]
Make sure the application for the file type (.vb) is installed
All my other forms work. So, I tried on the original problem as well, and it now says the same thing. If I add the form into a brand new project, then it works fine.
Also, my database file that was in my project just randomly stopped working, after making no changes to it and working on the "Testclient" for a couple hours.
I have researched this, and tried changing the "Signing" box, but that didn't change anything. I'm using VB.Net 2005.
EDIT: To note, on the database. When I try to compile, it gives the same error message now, but ".bkp" instead of ".vb". (BKP is a random extension I'm using. It's an Acess DB)
