Solution 1

Most likely the problem is inside the Form1 classes code. Put a breakpoint and then press F11 (step into) to see what's going on in there. Somewhere in there you use a reader without an open connection.

Solution 2

judging by the error message you may have not closed the connection anywhere in Form1 .You can easily resolve this by debugging as suggested by mika.

hope it helps :)
