SYMPTOMS
========
If you use an add-in to change the name of a UserControl, an access violation
(AV) occurs. The error message is similar to the following:
VB6.EXE - Application Error
The instruction at "0x004075a9" referenced memory at "0x0000000c". The memory
could not be "read".
Modifying the name of Projects, Modules, and Forms with an add-in does not cause
an Access Violation.
STATUS
======
Microsoft has confirmed this to be a bug in the Microsoft products listed at the
beginning of this article.
MORE INFORMATION
================
This appears to be an issue only when you load a project from a file and then
try to change the name of a UserControl in that project. The error message does
not occur if you create a new ActiveX Control Project and then change the name
of the UserControl.
Steps to Reproduce Behavior
---------------------------
1. Create a new Visual Basic add-in project.
2. Open the design window for the form frmAddin and replace the current code for
the click event of the OKButton with the following:
Dim oUserCtl As VBComponent
Dim oProj As VBProject
VBInstance.VBProjects.AddFromFile VBInstance.ActiveVBProject.FileName, True
Set oProj = VBInstance.VBProjects.Item("Project1")
Set oUserCtl = oProj.VBComponents("Usercontrol1")
' the following line causes the Access Violation:
oUserCtl.Name = "CoolName"
Unload Me
3. Compile the add-in DLL.
4. Start a new ActiveX Control project in Visual Basic.
5. On the File menu, choose Save Project, and then save the project files to a
folder.
6. If it is not already loaded, load the add-in by using Add-In Manager. The
name of the add-in should be My Addin.
7. On the Add-Ins menu, select My Addin.
8. Click OK, and note that an access violation occurs.
