My user has requested to be able to get anywhere from anywhere in the application.  I have buttons on the forms that provide this ablity.  How can I check if a form is loaded?  If a form is already loaded I don't want to re-load it.

You can just use the .Show method - this will load the form if it is not already loaded.

Calling for example Load Form2 will not cause the form to reload if it has already been loaded.  The Form_Load sub is called only when the form is either called the first time, or first unloaded, then called again.

If you still need to determine what forms are in memory, you can iterate the Forms collection:

Dim frm As Form
For Each frm In Forms
    If frm.Name = "Form2" Then
        Debug.Print "Form2 is Loaded"
    End If

Hope it helps!

Public Function IsLoaded(ByVal FormName As String) As Boolean
    Dim i As Integer

    On Error Resume Next
    IsLoaded = False
    For i = 0 To Forms.Count - 1
        If Forms(i).Name = FormName Then
            IsLoaded = True
            Exit Function
        End If
End Function

Dim FrmD As form1
If (IsLoaded("form1") = False) Then
        Set FrmD = New form1
    End If
