Article ID: 171555 - Last Review: December 10, 2003 - Revision: 2.0 FIX: More Than One Sub Main May Cause EXE to CrashThis article was previously published under Q171555 On This PageSYMPTOMS
If a project contains more than one Sub Main in different modules, it may
run as expected in the IDE and compile without errors in either native or p-
code, but will crash when run as an EXE. Visual Basic 5.0 will generate an
application error, such as:
"The instruction at <address> referenced memory at <address>. The memory
could not be "written"."
CAUSE
To avoid this problem, either include only one parameter-less Sub Main in
the project, or install Visual Studio 97 Service Pack 2 (SP2).
