I have a app that contains a usercontrol in the project.
The usercontrol is on one form.
When I compile it runs the usercontrol code during the writing phase of the
compile.
What causes this and is there a way to avoid it?

The compile errors out because in the usercontrol it calls a sub that has a
filename that is not defined yet  and is trying to open the un-named
file(gets defined in the main app when it runs).
I have a Debug.Assert False in the error handler and the compile writing
stops dead there.
I OK then I F8 it until it completes but I am not totally sure if the
compile is good.
No other errors occurr.

What's up with that?

Try checking the AmbientProperties object (UserMode) and see if
that will help....

Show quote Hide quote I just ran a simple test (added a Debug.Print "<eventname>" to a few events
and checked the immediate window to see what got printed) and confirmed the
Initialize event is fired during compilation.  This was a Standard EXE
project with a UserControl added to it.  I don't know if this event would
fire if the UserControl were instead part of an ActiveX Control project when
you compile (easy enough to test this too I guess....nope, not in my test at
least). I can't say I know why this event fires when you compile, but for
whatever reason VB instantiates the usercontrol during compilation (also
don't know if this would be considered a bug or if it's maybe documented
somewhere).

It looks like you'll just need to write code to deal with it. Perhaps you
can check to see if Len(filename) = 0 and not run your code to open the file
if it is (or better, only attempt to open it if Len(filename) >0). Or
perhaps you'll need to do something a bit more drastic. If worse comes to
worst and you can't work around this any other way, I suppose you could make
your UserControl an OCX instead of that module just being added to another
type of project.

I don't think you understood the problem. <g>

Show quote Hide quote Yes, some events are fired when you compile. But I think there must be
something wrong with the design. What UserControl event is triggering that
file read?  I think you should explain how your code works in order to help
you find out what's wrong and what to change. I can guess that you shouldn't
be reading that file at that time.
