Thank you! That’s a very useful method!

OpenForms doesn't have a Contains() method.

private bool CheckForm(Form f)
{
return(Application.OpenForms.Contains(f))
}

@PhonicUK:

Contains() method is not a member of FormCollection class. That would have been cleaner but there’s no Contains() method for this class.

Thanks

why not do…

private bool CheckForm(Form f)
{
return(Application.OpenForms.Contains(f))
}

Doesn’t require you to enter a loop, looks cleaner too.
