How can you implement scrolling using the CScrollView class as a parent when displaying a bitmap using CStretchDIBits? Everything I try just displays the stretched bitmap with the scroll bars, and when you try scrolling the bitmap just judders. I was able to implement scrollbars with a bitmap displayed using SetDIBitsToDevice by just using the device coordinates as the target rectangle origin, but this did not work for CStretchDIBits.
Can you tell me how you did that ?

Hi
Thankx for your explanations. I still have some problems.May be once I explain it, things wld be clearer. I have a bitmap on a dlg box, which am using SetDIBitstoDevice to display. From the resource I have place a horizontal and vertical scroll bars. My plan is to trap these scrll bar images to make the image scroll.
But I am struck up there. How do I "connect" the bitmap to the scroll bars ?
Can you please expalin me how you did that in you app ?
Is the way am doing is right ? Or is there any better way of doing it ?
Thankx in advance
