Selecting Region of Interest in images

[ashsri]

Hi,

I want to select a particular part of the image by drawing a frame around them(like in paint brush) or by clicking on two points on the image to indicate the range of selection. I do not know how to do it in VC++ and also I am using CXIMAGE for processing images. Please do help me, I know this is big...but please give me some tips.

Thanks in advance
