How can I cause a secondary window of an application to become active and have focus. I reviewed all the MSDN documentation but still can't seem to get it to work. Essentially I have an application and based on various menu selections I want to display different windows with their own controls for processing or data input

Can anyone provide an example

Thanks
Phil

You could try to build the forms separately with a picturebox as the
container and use the API to switch back and forth from screen to screen...
e.g. Build a wrapper class for the handlers... based it on the API
"setparent" and pass the window handles... This one below is 6, but should
port easily to 7.

Public Function RetToParent()
On Error GoTo ErrHandler

Dim lRet As Long

'could be no child form loaded
If mchildPicMainhWnd = 0 Then
Exit Sub
End If

'return the child pic window and remove the references
lRet = SetParent(mchildPicMainhWnd, morigParenthWnd)
If lRet <> 0 Then

'*** use the error handling class here ***
End If

morigParenthWnd = 0
mchildPicMainhWnd = 0

Exit Sub

ErrHandler:

'blah blah blah

End Sub

I appologize but I am neww to Visual Studio and C#, but
Isn't there a way of just having a project with form1 and form2 for example and form1 has a button on it that when it is pressed it shows the second window (Form2)?

FORM1.SHOW VBMODAL

Sorry Phil, I must be more tired than I thought. I didn't see the C#
there.

Thanks G.

The Show command was exactly what I needed ...
