Hello,

I would like to use ASM to substitute other programming languages, because it's simpler for me. My question is that I should use dialog boxes as main window for larger programs or it would be better to use CreateWindow.

My problem is that I want to make a windows program for educational purposes, and I started to make a Dialog Box resource with WinAsm. I don't want to "code" the properties for the window, I prefer to do this visually. (I was using Visual Basic, so I am used to visually designing the dialogs).

But, I cannot control the controls on the Dialog Box Resource. I've created a scrollbar, but I don't know how to use it.

I've found functions in the Win32SDK, but they require the hWnd of the scrollbar...
The problem is that I don't know how to obtain it.

Maybe the hWnd is returned into the "eax" register, when the control is created programmatically using CreateWindowEx...
But, as i mentioned before, i prefer designing the dialog/controls visually..

Thank you.
Adam

Welcome admc,

This is up to you. You can use any method you like.

You always give "commands" to controls using their handle.
The GetDlgItem API returns the handle of a control.

I hope this helps,

Thank you!

Now it works!

Hello,

Now I tried to make a Group Box into my dialog box window and put controls in it, but when I started the program, it didn't redraw the frame, so it put out the frame border and left the window in the back inside.

How can I redraw it?

UpdateWindow didn't work, I tried it with the handle of the dialog box window, and with the handle of the groupbox.

Hi Admc,

Could you post your code?

I am not sure if I get what you mean. Normally there is no need to call InvalidateRect and UpdateWindow on a dialog box, unless you have done some custom drawing (for instance), and an event has occurred that necessitates repainting.

If you post your code I am sure we can help a little more.

Cheers,
Andrew
