thank you for your suggestions.
Actually, I'm a beginner in Visual C++, even in C++.
so that, I need learn more.

I have searched this topic before, but most of all used for Single Document Project type.

Can you give me short explain, what do I need to reach my aim?
I means another functions except FillRect that need to draw a shape on dialog based form.

Thank you for your help and support.

Changing the OnButton1 handler as suggested here [^] didn't help?

to CPallini,

Thank you once more.
Sorry if my response was late because my internet connection is slow.

Yes, I already tried your suggestion and it can fulfill my aim.
but i still confuse about some things - I have written on previous post message.

Thank you for all...

I just want to understand about FillRect and another function that I should used if I want to make my program in other ways.

I'm a beginner in C language, so that I need to learn more about it.

Thank you for your kindly support and answers...

First, please use code block button when posting code snippets.

As about the code, you should never call OnPaint() explicitely in your code, change from

Eka Candra wrote:
void CGambarDlg::OnButton1()
{
red = green = blue = 255;
OnPaint();
}

void CGambarDlg::OnButton1()
{
  InvalidateRect(NULL);
  UpdateWindow();
}

See documentation (InvalidateRect [^], UpdateWindow [^] for details).

Thank you for your advice.
I've tried. But, I still confuse about explain of InvalidateRect function.
Why this function filled with NULL value? how about value of coordinates rectangle' edges?
What is it means, this function force the program to redrawn this form dialog? In other way, it is force to run codes in OnPaint function, is it correct?

Your answer really help me, thanks a lot.

Consider reading the fine manual or docs from Microsoft. They havent not only written about the parameters and their usage but often some smple code to illustrate that. Blush | :O

As you may read in the documentation, InvalidateRect(NULL) call (followed by the UpdateWindow() one) make the system posting a WM_PAINT message (so that OnPaint handler is called). Using NULL as argument means 'the whole client area should be updated'. If you need to update only the rectagle area (that's good, it is better to keep the update region as small as it can be), pass a pointer to CRect having the proper dimensions.

Thanks a lot for CPallini and Superman...

Would you advice me about tutorial for GDI in Dialog Based project?
When I was searching this topic on internet, most of all are explained for Single Document Type.
It is same if I used Dialog Based and Single Document Based for a Form application?

Thank you...
