When to put code in a form or module?

Hi,
This may be a fairly basic question but most of my programs are formless. I'm now beginning to create programs with forms.

Is there a rule-of-thumb when your code goes in the form or a seperate module?

Thanks,
Al.

General i write the code in a Module when i use the same code from other forms in the same program.

I hope that helps you. :) :eek:

If you have only one form, it doesn't matter. When you write an application with more than one form, though, it becomes more efficient to put it in a module. Say, for example, you want to use a particular API in two different forms. Rather than define it twice as Private in both forms, simply putting it once as Public in the module saves lots of space in the end. Also, it is easier to manage all your code when you don't repeat it. If you have a group of code that you repeat over and over, make a sub in the module and call it whenever you need it from the form. Like if you want to do 1, 2, 3, a, b, and c in that order frequently throughout the program, put a sub in the module that says

Public Sub DOTHIS()
Do 1
Do 2
Do 3
Do a
Do b
Do c
End Sub

and call it by just writing DOTHIS in your code. The whole idea is to save space by preventing repetition.
