Good Day!

Here is a question for those who know VB quite well. When my EXE
(created with VB 6.0 SP5) runs on certain computers, it displays a
"Run-time error 380 Invalid Property Value".

I modified my EXE to write a logfile as the software loads. It shows
that the error happens after Form_Initialise is completed, but before
Form_Load is started.

After Form_Initialise, but before Form_Load, VB loads and initializes
the controls on the form. The Form_Load event is raised when all the
controls on the form were created and initialized. But, that never
happens. One of the controls (components) gets assigned a value that
it cannot digest and that triggers the 380 error.

My question is: tell me how to find out what control and what property
is responsible. The interval I am talking about cannot be watched with
breakpoints. There is no visible code that I can observe.

Is there a method or a tool that would allow me to pinpoint my problem?

Thank you all in advance!
Eugene

Oldman-ga,

If you open your VB project in the IDE and start it by pressing F8,
you can then step through your code line by line by pressing F8. Based
on your description, this may or may not reveal anything.

If not, you can make a copy of your project, then you can remove
controls one at a time until the error goes away. Once you know which
control is causing the problem, you can focus on known issues for that
type of control that cause this error. There are a couple of controls
that are prone to this, especially if converted from an older version
of VB.

Does this help?

The problem is that I cannot reproduce the "Run-time error 380 Invalid
Property Value" on any of my computers. I need to find a way to modify
my EXE in such a way that, when I give it to a client who gets this
error, we can find out what control and property is causing that
instead of getting just the error message. Please tell me what kind of
debugging I can incorporate into my EXE.
