As in parent form, do you mean the calling form (Me)?

As in:

////////////
Dim form As New Form1()
form.Show()

Me.Close()
///////////

Thanks,

... and in addition, the startup object in the project's properties must be
changed to Sub Main (before, the "application framework" must be disabled in
VB 2005), which must contain:

dim f as new StartupForm
f.show
application.run()

And, Sajit, you must call Application.ExitThread in order to close the
application.

An Application.EnableVisualStyles() should be in your Sub Main too
(unless you like the "old" looking UI controls)

Thanks,

Sajit,

Your question depends totaly how you start your forms (about 12
posibilities).

However as you write it, it is impossible to close a calling object from a
detail object, what is happening in your situation.

Normally a called object will be garbaged when it goes out of scope.

If it is that you want to make your form invisible, then do that, that can
in different nice ways. You can even make it transparant from the first
version of dotnet on every Windows (NT based) OS by using the form opacity
property.

Could he not define the form in an invisible 1st form, as a public
shared variable?
That way if Form2 calls Form3, Form2 can be closed because Form1
actually has the object?

Miro,

He can do it in much more ways, however there is an inbuild Application run
in a form as you don't declare it seperatly. Therefore it is exactly as you
write.

Have a look at the answer from Armin, I don't know what it is now, but in
past he was as far as I remember me alway using the application run in a
seperated module.

Like others who are interested in this problem, have a look at that nice
answer from Armin some days ago.
