GUISetState (@SW_LOCK) on C++

How to lock the window to avoid repainting on C++ (C++ Builder 6)?

[PsaltyDS]

Guessing, 'cause I'm not a C-guy, but is it just SendMessage with WM_SetRedraw?

I find solution, easiest way:

LockWindowUpdate(Form1->Handle)

LockWindowUpdate(NULL)

Best way:

PAINTSTRUCT ps;

BeginPaint(Form1->Handle, &ps);

LockWindowUpdate(Form1->Handle);

...

LockWindowUpdate(NULL);

EndPaint(Form1->Handle, &ps);

With this way other windows will redrawn without flicker
