Rect flickrs outside of the the app area

[gabbana]

Hello, I have the following problem: I painted a rectangle with a text outside of my app on the screen in the WM_PAINT message. The Problem is that it flickrs very hard. The code I use:

	hdc = GetDC(NULL);
	SelectObject(hdc, GetStockObject(WHITE\_BRUSH));
	RoundRect(hdc, 10, 10, 100, 40, 9, 9);
	rc.left = 10;
	rc.top = 10;
	rc.right = 100;
	rc.bottom = 40;
	SetBkColor(ps.hdc, RGB(255,255,255));
	DrawText(hdc,L"Hello",5, &rc, DT\_CENTER | DT\_VCENTER | DT\_SINGLELINE);
	ReleaseDC(hWnd,hdc);

I also tried using the WM_NCPAINT message but the it destroys the complete app frame. Thanks for help. bye, gabbana

Okay i solved the problem with the double buffering system. I created a new DC and a Bitmap and draw into this dc and made an bit block transfer at the end into the right DC.
