hi i'm in middle of building an application and something got corupted and the solution has 2 errors and i don't know how to fix it
when i run the app it comes up the msg that there is errors and i can run the last successful build i'm interested if there is a way to recover the program solution from the last build or a othe way that i can undo the error?

Are you saying the build errors but doesn't specify what the error is? It should point to the class and line when the problem happened. To go back to a previous build you would need to have been using some form of version control

it points where the error is but i don't know how to fix it
the error happened when i changed a table adapter so it seems that the forms that were connected to the tableadapter got corrupt

OK... How about posting up the error for us to have a look at?
