Using VB6 writing a program wich is growing, and keeps growing, and still adding code.
As a 'old' dos-programmers I was used to the fact someday its big, to big. Then I had to split my progam in pieces and chain them.
Now I don't have clue how VB handles memory, ny program runs on a 1 giga mem. system, will I run in a problem some day that the
program will be to big?. If so I have allready to start considering now to split, like qbasic-dos.
I do use (offcourse) a lot off forms with all their work and functions, wich are called by the user from the main-form/module.
Can I go on adding forms to the main-program?,  or run in error?
So I like to know how VB6 handles this, and if this ok to do.

These days I don't think you have much to worry about. Just how big is the EXE file?

That is not big at all. When you get to around 10 or 20 MB we can talk.

The only "memory" issues I have ever run into (and I have built some large apps) are recursive calls - before you know it you have blown the stack. But you will see that right away.

No worries, mate! Code away!

Ok,  by recusive calls you mean like in Qbasic gosub/return??,  or just call from a private sub another private sub?

A recursive call is when you call the same routine from within that routine. This technique is often used in sort routines or routines that parse directories. It can also occur if an event handler generates more events that trigger that same event hander.
