Mousing a cropping selection box over an image

[button71]

I am using

.container1.imgcontrol1.Picture = (mypicture)

( mypicture being the fullpathname of a say jpg file).

to put a picture in a container on my form.

I would like to know if it is possible to have a control which sets the mouse to draw a selection area on the image - collect the coordinates - and return the amount of cropping on each dimension.

The image's mouseDown and mouseMove events both know the co-ordinates of the mouse position so you should be able to do some arithmetic with these and with the image coordinates. Drawing and redrawing the box as the mouse moves will be more difficult. I think you'll need to alter the form's drawMode so that you can undraw the lines.
