View 1 RepliesI am trying to incorporate in my vbdotnet application a form in which I would like to make a thumbnail from an image. So what I have is two picture boxes, one with the source image and the other with the destination image, I would like to crop the image from picture box 1 and display it on picture box 2, but the way I wan to crop it is not giving the coordinates of the selected area box but to simulate a selection area box in which the mouse can move the box and select the area of the picture to be cropped. This selection area box would give me the coordinates i need in order to proceed the cropping. The problem is I don't know how to create this selection area box. It is like doing the cropping on a graphic design software like Macromedia Fireworks, Adobe photoshop, even paint.

I am on my second project. I made the mistake of trying to use my first project as a template thinking there was a 'Save All As...' which I found there wasn't.
I went through the whole project and now it is forcing me to use the folder names that everything is saved in from my first project and my professor wants the directories named a certain way.
If I try and change the names of the folders, then upon re-opening my solution I get errors because the directory has changed.
Is there a way for me to change the directory names and not have my program fall apart? Or re-direct it where to look after I change the folder names?

I want to be able to open the file's containing folder, then switch to thumbnail view, and the thumbnail will be displayed as the image for the file.
