RE: EuGrid - was Runs w/Interpreter but not as .exe
Phil (and others),
I've done some more testing and here's where I stand:
So far only 1 of my bound programs are having this problem. The problem
is also not related to OS level as I can reproduce the problem on
Win95/Win98/Win2K. The exact error message I'm getting is:
The instruction at 802584ad referenced memory at 802584ad
The memory could not be read from
What's interesting here is that the instruction and memory location are
the same. Is this normal for Windows programs?
I've narrowed down the line causing the problem (by using puts) to a
createEx call of a drop down list. However I feel that by moving code
around it would probably happen in a different spot.
The other consideration is the include file the problem is happening in.
Both the main .exw file and the .ew include file have a main window (0
parent). The window in the .ew file may or may not be displayed,
depending on the command line parameters passed. I wasn't sure if
having two windows as the main window would be a problem.

The fix still is to use V1.0 of EuGrid.
