SYMPTOMS
When running in debug mode using a dynamically loaded dynamic link library
(DLL) such as an OLE control with a long file name or an .exe file with a
long file name, you may find that it doesn't break at set break points. You
may be able to set break points both before starting and while it is
running, but the debugger will not break on them.
When starting the debug session, you may see the following message from the
Microsoft Developer Studio:
One or more breakpoints cannot be set and have been disabled.
Execution will stop at the beginning of the program.
If you receive this message and then attempt to set a break point in your
code, you will not be able to do so and the Developer Studio will beep. If
this message does not appear, you will be able to set break points, but
they will be ignored.
This does not occur in Windows 95
CAUSE
The name of the DLL has more than eight characters.
RESOLUTION
Use DLL names of 8 characters or less.
STATUS
Microsoft has confirmed this to be a bug in the Microsoft products listed
at the beginning of this article. This problem was corrected in Microsoft
Visual C++, 32-bit Edition, version 4.2.
