Modal or Modeless

[Gary Staunton]

Is there an API that can determine how a form has been loaded?

IE: Form1.Show vbModal

On Form1 a Command button that would be clickable and tell you that the form
was loaded Moadlly or Modeless?

I don't know of any magical way to know that a form was created modally or
modeless. However, it's easy enough to keep track of this in your own
application. Just add a property to the form that you set before showing it to
indicate what mode you used when you called the Show command.

Thanks for the info Dan.

I just thought that there would be a simple API call as Windows does know
if the form is loaded either way.

You would think so, wouldn't you?

Sometimes things don't make a whole lot of sense:-)

Gary: I don't think Windows does know. If you use Spy++ to examine the
properties of a modal window, you'll find that there's nothing to
distinguish it from a non-modal one. I'm pretty sure that when you show a
form modally, Windows simply disables all other top-level windows in the
application.

An alternative solution, which avoids the need to explicitly set a property
before showing the form, is to create a drop-in replacement for the .Show
method (e.g., .ShowForm) and call it instead of the standard method:

Public Sub ShowForm(Optional Modal As _
FormShowConstants = vbModeless, _
Optional OwnerForm As Object)

' Save modality in module-level variable
m_bModal = CBool(Modal)
' Show the form
If OwnerForm Is Nothing Then
Me.Show Modal
Else
Me.Show Modal, OwnerForm
End If

End Sub

Windows must know, because when the form is unloaded the other windows become
enabled again.

Or else VB knows, and VB is the one showing the window modally by telling
windows to disable the other forms in the App.
