Hello I can't see the error every time I run the program It always say not responding and automatically ending the program . Any suggestion what to do??

It could be an error when the form creates, or you form load sub has something that crashes it. Hard to tell without any code - look there first.

Wrap the code in a try/catch.. have it write out the error to the console, toa file, to a messagebox... or just 'stop' the execution to see it..

The most simple thing you can do is to start program by pressing F8 key. Observe what's going on, and press it again. Repeat this (stepping through the code), until you come to the line, where error appears. That way you'll find where your problems begin.
