I'm trying to write a very simple DarkGDK C++ program to count the number of pixels that match in color to the area I click in and found out that dbPoint does not appear to work properly in Vista but it does in XP. The code compiles and runs just fine, it just does do what it's supposed to.

I did some research and found there are other commands such as dbCircle, dbEllipse, and dbDot that do not work with Vista.

Does anyone know a fix or workaround for this?

Does dbPoint work properly in Win7?

Hard to believe the folks at TGC haven't addressed this issue already. I teach a course using DarkGDK and it's pretty frustrating to teach when several students can't get their programs to work properly because they have Vista.

Unfortunately this is a known problem and not fixed yet. Feel free to add your comments to the bug report thread. I could only describe my experience there but it would have been good to see other users chime in too, since there were several complaints about this - but not in the bug report section.

Or maybe, raise a new bug report thread because the dbPoint command has not been reported yet.

Workarounds: Here are functions which you can substitute for dbCircle and dbEllipse:

Instead of dots, maybe use dbBox or a two-pixel long line. (I think one-pixel lines do not appear either.)

I don't know a workaround for dbPoint. (The only thing that comes to mind is converting the screen picture to a memblock and read the bytes - if it is feasible at all - but that's too complicated to be helpful.)

I don't know how these commands behave on Windows 7.
