Datagridview, Saving data in many Excel rows

Looks like I am gonna have to abandon my project then if nobody can help me :(

Thanks to anyone who replied

try to run your application in debug mode and then step through each line of your code in the loop. you may use the watch window to inspect the variable contents when the error triggers.

i also noticed a Parameters.Clear() inside the loop.

Cheers Thread1 - I will give it a go and see what I come up with ;)
