Multiple Forms & Me.Close

[Herwig]

Hi all,

I've got an application with multiple forms: Form1, Form2, Form3.
In this application there is also a Module: Module1.

The main window is Form1 which is launched at startup.
In Module1 there is a function which opens and closes Form3:

private Function SomeFunction()
Dim PopupForm As New Form3
PopupForm.Show()
'Do something here and when done:
PopupForm.Close()
PopupForm = Nothing
end Function

As long as I call this Function from Form1 everything is OK.
As soon as I call Form2 from Form1 and call this Function from Form2:
1. Form3 won't close
2. Form3 will only close after Form2 has been closed (I've added a
Button which calls Me.Close(): I'm able to call anything from this
form - except: Me.Close() )

My Problem: I've got an application with several forms from which I
need to call a Function from a separate Module which opens a new form
containing progress information. This form needs to be closed
automatically after the process is done. How can I do this (not only
from my startup-form)?

yours

Hello Herwig,

The problem that you are seeing is due to a known issue in the .NET Compact
Framework: modeless form cannot be closed when it is shown by modal dialog
until the modal dialog is dismissed. In your case, a workaround would be to
call PopupForm.ShowDialog() instead of PopupForm.Show(). Hope this helps.

Thank you,
Sergiy.

Thank you,

meanwhile I have changed Form2.ShowDialog() to Form2.Show(). This also
works.
Sorry for bothering everone with a known issue,... VB&.NET&CF is still
something new to me
