Is this structure ok? and listview problem

[nikink]

Hi all,

So I'm building my first gui app, and I'm having a few doubts about the structure of it. I've replicated it in very basic form below, and I'd really like to know if I'm doing it correctly, or whether I'm screwing things up in ways I can't foresee.

My second question, is about the listview window. How can I get data from one list to the other? I thought drag/drop, but a button would be good too. Maybe better? And how can I make it so that the user can use ctrl to multiselect?

Any help appreciated - I'd rather get it right now, than plough through to the end and discover I've missed something fundamental...

Why need to use several "GUIGetMsg() loop", use one main loop. Don`t need to create child GUI in function, create them in a script begining, then show or hide when function calling.

Ummm... cuz I'm a newb???

How do I do it in a better way?

And any ideas on the drag and drop problem?

At this forum you can find a many example about "how create a multi GUI".

Ahh, thankyou very much.

I have seen lots of multiwindow gui examples on these forums, but they just confuse me, and so many lines of code I start going crosseyed trying to follow them!

And I created my example the best way I could think of, using the help file as a guide.

Is there a reason to prefer your example's way, than mine? Efficiency or ease of maintenance? Or is a case of your way is standard, so that's the way it should be done?

I am trying to understand, but like I said, I'm new to gui programming.

(I'd guess my way would endup using too much cpu once a dozen or more windows are open and all the while loops are operating...? And multiple while loops would also be needless wasted lines of code?)
