I guess Tuition is nothing. so Nothing.tostring will raise this kind of exception. I suggest to do
MsgBox(SQL) just before your Try block and see how your SQL Query looks like. eventually even take this string and execute it directly against the database to validate the result.

The problem lays in your BackgroundWorker1_ProgressChanged procedure.
You can NOT access controls (which were created in the main thread) from any other thread without using delegates.

Same problem + solution.

no, didn't see a reason to do that.
Is it working now?

try

InstituteBaseDataSet.acceptchanges after your inserting

oi sry i just saw i missed something
it should be "for each ctrl as control in Form1.controls"
