Window scrollbar and Mouse Draging

[wanga]

Hi,

I am doing bitmap image processing using VC++ MFC. I already have a window scrollbar to modify pixels. But it is not a real time -- that means when you click the mouse button and the pixel value will not change until the button released. Is that possible to make it real time. I heard CTime can do that. But I never use it. Can anybody help me?

THANKS.

Walbert
