Thanks...

now i have the followinf problem:

in old VB i could set startup to be a form or submain

now i don't have SubMain on the list to set it as a startup of my
application...

but i found a checkbox 'make a single instance app'
i checked that and compiled the app...
now when i try to run the second instance an error accours and the first
instance is crashed...

That's "Main" - not "SubMain".

That's what i meant... it's a habbit of calling it sub main because it
can't be a function...

But still... it's not on the list... (i am rather new to VS2005 so i am
still finding things thet are not on the same place they were in VS6...)

I wish I could help more, but I do almost no work in VB these days. I do
know that the IDE hides a lot of this stuff from you when working with VB
(NOT a good idea, IMHO). But I don't know exactly how it is hidden, or how
the IDE works with it.
