Yes I did try it. The problems with using invisible main form I have
encountered so far are like that:
1) when current form (pretending to be main) gets minimised it does not
completely disappears from screen as real main form would do, but stays
minimised on the _top_ of task bar. This is confusing for a user.
2) clicking application icon _inside_ task bar does not restore pseudo-main
form, as Windows sends messages to real main form which is hidden. To handle
this I do this:
procedure TFormRealMain.OnActivate(Sender: TObject);
begin
ShowWindow(FormPseudoMain.Handle,SW_RESTORE);
end;
This solves problem 2 but introduces problem 3
3) When user closes last non-minimised application, Windows may, having
nothing else to focus on, focus on my application's icon on (inside) task
bar. This triggers OnActivate event and above shown code is being executed
and accordingly my current minimised form gets unwillingly restored. If I
knew how to detect if it is user clicked app.icon or app.icon just got
focused by Windows.
I do not know may be there are more problems like these to be discovered
while using hidden main form approach. So I'd prefer to somehow change main
form at run time to gain all normal behavier for my application.
I wish I was an internet developer. Would I care about all this then ?

Alex
