Drawing a Bounding Box rectangle in vb.net 2005
Posted on 2009-05-14
I never thought I'd actually be writing on how to do this, but I am having nothing but trouble getting this to work.
I have a picture on the screen. I want to give the user the ability to crop the picture, so I have a crop button on the toolbar. When cropping starts, I want the user to be able to click and drag around the area that they want to keep within the picture. I would like to draw a rectangle AS they move the mouse.
What I'm running into is I can do the draw rectangle, but as the mouse moves, another rectangle is created and another, etc. so I end up with a series of rectangles rather than one when I'm all done.
In vb6 world, I used a "shape" to accomplish this and just kept moving the bottom right point of the shape. I just don't know how to do this in vb.net 2005
Thanks so much
