Hi. I think the easiest solution to this problem, is just to use relative paths.
Say you have a folder, within the main folder, called images. You can access it easily, using a relative path.
Instead of doing this...
Open "C:\myDemo\images\myimage.bmp"...
You can just do it this way, which will never fail.
Open "images\myimage.bmp"...
I hope this helps. I've wanted to try your demos, but it's very frustrating when they don't run.
