FIX: VB5.EXE Application Error with UserControls in Project (189499)
The information in this article applies to:
- Microsoft Visual Basic Learning Edition for Windows 5.0
- Microsoft Visual Basic Professional Edition for Windows 5.0
- Microsoft Visual Basic Enterprise Edition for Windows 5.0
This article was previously published under Q189499 SYMPTOMS
Large projects or project groups that contain UserControls that are not
compiled OCXs may experience the following application error:
The instruction at "0x0fbb54bb" referenced memory at "0x00000000". The
memory could not be "read".
This behavior occurs when either compiling the project or opening a form
that may contain a UserControl.
CAUSE
The UserControls contain either references to global objects or circular
references to Forms/Modules within the project.
RESOLUTION
There are three possible resolutions to this issue: - Select Options from the Tools menu, select the General tab, and then
deselect Background Compile.
- Use compiled OCXs in the project instead of having a UserControl
project as part of the Project Group.
- Late bind global object references within UserControls and attach them
to instances at run-time.
STATUS
Microsoft has confirmed this to be a bug in the Microsoft products listed
at the beginning of this article. This bug has been corrected in Visual
Basic version 6.0.
