"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

In the absence of a more subtle approach, enumerate through the Forms collection looking for the form in question ?

ie.

condition = false
For each frm in Forms
  if frm is blah then
    condition = true
    exit for
  end if
next frm

Fine but what is blah? That is what I cannot work out.

Oh... sorry. An example...

Assume you want to see if Form2 is loaded. From somewhere in your code, do this...

    if FormLoaded(Form2) then
      ' do this
    else
      ' do that
    end if
 
....and create a function like this.


Public Function FormLoaded(ByVal Target As VB.Form) As Boolean
    Dim Form As VB.Form
    For Each Form In Forms
        If Form Is Target Then
            FormLoaded = True
            Exit For
        End If
    Next Form
End Function
