Form Load

What happens in the Form Load? If I try to retrieve information from a database (using a DataControl and TextBoxes connected to the database), I can't get the program to work. I never get the data from the database. If I place the exact same code in a Timer control, it works just fine.

I've also tried to "Call" the same code in a procedure I created--no luck that way, either. There must be something going on in the Form Load routine that prevents certain code from running properly.

Unfortunately, you're right--the Form Load is not the place to put data control and data bound code, because the controls on the form are not fully initialized yet. You should put it in the Form Activate event. Since this event fires every time the form gets the focus, make sure to use a static variable to determine whether the code has already been executed.
