Hi All,

Relativley new to .NET and I'm wondering if its possible to enumerate all
instantiated WinForms so I can determine if a window has been created, and
if possible obtain a reference to that window. Basically having knowing if a
non-modal dialog is open without having to use variables to keep track of
whether it is open or not.

Thanks in advance!

In .NET 2, there's the Application.OpenForms collection that has a list
of (you guessed it) open forms (not instantiated windows!). Generally,
you have to keep track of your forms yourself, if you need to know
exactly which ones you have created.
