InvalidOperationException before the form is loaded.

I got the following message before the form was loaded. What was wrong?

System.InvalidOperationException was unhandled
Message="An error occurred creating the form. See Exception.InnerException for details. The error is: Object reference not set to an instance of an object."
Source="Project1"

Have a look at the line where code stops, one of the objects there is Nothing.

It didn't go that far. It didn't point to any line. Thanks.

In that case you are going to need to post the code you are using.
