SYMPTOMS
A project containing a class module with a large number (approximately
2000) of public class module variables will run successfully in the IDE but
will cause an "Out of memory" error when you attempt to compile the project
to make an executable file.
CAUSE
There is a limit to the number of public members you can put in a class
module. The out of memory error is caused by exceeding the type library's
(object library) capacity limit for definitions. When making an executable
file, Visual Basic creates a type library and creates a typeinfo (an object
description) for all the basic classes. The public members of the class are
moved to the typeinfo in the type library. There is a limit (approximately
1100 members) to the number of definitions that you can have in a module.
RESOLUTION
Limit the number of public members in a class.
STATUS
This behavior is by design.
