1. Open the image
2. Show the image using picture BOX
3. Scretch the image if not fit into the Picture Box
4. Now i want to select an area in a pictureBox using pointer so i can crop the image in selected area and show it in another form..how can i do that..please help thanks for advance

An unhandled exception of type 'System.NullReferenceException' occurred in microsoft.visualbasic.dll
Additional information: Object variable or With block variable not set.
