Microsoft Visual Studio 2008 using Microsoft net framework Version 3.5 SP1
I am attempting to modify a working form. Upon initially adding buttons / fields and 开发者_如何学Pythonthen subsequently running the program, the form threw an exception.
Exception :
"ArgumentException was unhandled by user code"
"Cannot add primary key constraint since primary key is already set for the table"
From what I have found it has to do with trying to modify or enforce constraints on an inherited data-table/database. Is there any auto generated which could be causing this error?
Thanks for any help.
As pointed out in my initial question I was searching for the function that I could delete to keep this from happening. And even though @jeroenh thought so valiantly that I did not give enough information to answer this question, I'd like to point out the function is
.Constraints.AddRange()
^ you'll note it had to do with constraints from a data-table.
