Re: Draw OpenGLScene without WM_PAINT

Hi Clemens,
thak you very much for reply, probably I understand your suggestion, I
have implemented new instruction in the code

void COpenGLControl::OnPaint()
{
	if(*datoOK)
	{
		InvalidateRect(Prova, true);
		openGLDevice.makeCurrent();
		DrawGLScene();
		*datoOK=false;
		temp_stato_old=tab;
	}
	else
	{
		ValidateRect(Prova);
	}

}

"Prova" is CRect ogl windows where i draw with "DrawGLScene"

My idea based on Clemens's suggestion is that when the new data is
available I use InvalidateRect and when windows call WM_PAINT but the
data is not availabe I use ValidateRect.

Unfortunally, with this code the ogl is freezed, probably I don't use
correctly InvalidateRect.
