SYMPTOMS
========
When trying to set the Count property of the Forms collection, the following
error message is displayed:
Error 380 - Invalid Property Value
This error message is incorrect. Visual Basic should display an error message
indicating that the property is read-only at run time.
RESOLUTION
==========
Do not try to set the Count property of the Forms collection. This property is
read-only because it describes the number of open forms of the project. The
Count property can only be set indirectly by loading and unloading forms.
STATUS
======
Microsoft has confirmed this to be an issue in the Microsoft products listed at
the beginning of this article. Microsoft is researching this issue and will post
new information here in the Microsoft Knowledge Base as it becomes available.
