- We have a problem with a bitmap graphic placed in an CEditView derived window.
- The graphic is similar in functionality to the breakpoint that Visual C++
- displays in its source window and must follow the scrolling action. The
- graphic is displayed using a CDC object and BitBlt.
-
- On all our computers (mostly Pentiums) the graphic shows up properly in
- Windows NT and Windows 3.1 (using win32s) and Windows for Workgroups 3.11
- (also using win32s). We have tested it on slower machines and under heavy
- resource usage (using Stress App). The graphic displays properly.
-
- On our clients computers (two of them anyway) the graphic does not display.
- One of them is running Windows 3.1 on a 90 Mhz Pentium, the other is running
- Windows for Workgroups on a 33 Mhz 486. We have looked at their computers
- in both VGA and SVGA. Their available user and GDI resources are in the 65%
- to 72% range and plenty of memory is available, yet the graphic does not
- show up.
-
- I am at a loss to find the common element. Does anyone have any ideas of
- where to look? Has anyone experienced a similar problem.
