Q: OnLoad

[Geoff Jones]

Can anybody tell me the event I should use if I want a OpenFileDialog to
open as soon as a from has displayed? I tried putting it in the forms OnLoad
but this means that the form isn't fully displayed until the OpenFileDialog
is shutdown.

Many thanks in advance

Geoff,

Try putting Me.Show before calling the openfiledialog's ShowDialog method.

Geoff,
Have you considered using the Activate event?

Something like:

Protected Overrides Sub OnLoad(ByVal e As System.EventArgs)
MyBase.OnLoad(e)
AddHandler Me.Activated, AddressOf MainForm_InitialOpen
End Sub

Private Sub MainForm_InitialOpen(ByVal sender As Object, ByVal e As
System.EventArgs)
RemoveHandler Me.Activated, AddressOf MainForm_InitialOpen
Dim dialog As New OpenFileDialog
dialog.ShowDialog(Me)
End Sub

The AddHandler & RemoveHandler ensure that MainForm_InitialOpen is only
called once.

If I had a number of forms that need the "InitialOpen" event I would
consider putting the above code in a base class that raises an InitialOpen
event, when the first Activated event is called...

My other thought was the Application.Idle event, that you also only allow to
be called once.

Hope this helps
Jay

Thanks Jay, that is most useful.

Herfried,

Although it is more work, do I like the method Jay shows more.

I am in doubt what I will show next time, when this question is asked.
The way you show it is understandable for everybody, Jays is in my opinion
better.

Herfried,
Why the DoEvents? I didn't notice that we needed it, hence I left it out. Am
I missing something?

Its nice to hear about the .NET 2.0 Form.Shown event. I missed it when I was
looking thru the "what's new"...

Cor,
FWIW: Herfried's example is almost how my example started out, I had a
Private field instead of a Static variable. Then I thought it would be just
as easy to use AddHandler & RemoveHandler to control the event being called
only once. Ergo the version I posted.

I think its good Herfried showed the alternate method (a field instead of
Add/Remove handler)...

No, you are not missing something. The 'DoEvents' can be removed.
