Why does the following slightly modified code cause an exception to be thrown
on the Application.Run Line?
Public Module Program
Public Sub Main()
Dim f As New Form1()
f.Show()
Application.Run ()
End Sub
End Module
In Form1 button 'Click' event handler:
Dim f2 As New Form2()
f2.ShowDialog() Note after return from this Dialog, an exception is thrown.

What is the deeper reason that you use this code forever. \\\ Public Module Program Public Sub Main() Dim f As New Form1() f.Show() Application.Run () End Sub End Module ///
(This is a serious question)
Saying it in otherwords what is in your opinion the advantage above the
build VBNet method in a windowform project.

Saying it in otherwords what is in your opinion the advantage above the build VBNet method in a windowform project.
The built-in possibility of setting the startup form doesn't provide a way
to call 'Application.Ru n' without passing a form to it. In other words, the
'Sub Main's code is generated by the compiler automatically and doesn't give
you the control to do that. The code above does not suffer from the problem
that closing the main form closes the whole application because it's lacking
a message pump after the startup form has been closed.

Herfried,
The only argument I read here is the aspect of clossing the mainform, where
I see no reasons for, but I will not tell direct I disagree about that.
However than has the main really to be the main of the project and than
should there not be any form call from another place in my opinion. I think
that any tree structure inside a form node than is not right.
The load event in a form does so nice everything before the showing of the
form. Your arguments about this looks for me more something of behaviour
from an old VB6 programmer who is afraid that they will change that nice
behaviour again (Or maybe it was already like that, I don't remember it me
anymore).
However just my thought of course.
And feel free to do it your way.

It seems to me that you didn't get the point of what I am saying.
The application is started.
'Form1' is shown.
'Form1' is closed.
'Form2' is shown.
'Form2' is closed.
...
The application terminates.
How would you do that without a custom 'Sub Main' and without using ugly
'ShowDialog' hacks?

When this is consequently done, I said that I agreed (however than no shows

If I try a simple example it seems to work OK. However, my application is
too complex to post here. I did find out that if I delete a line of Code I
had, "Application.En ableVisualStyle s()" in my sub main, my application works
ok but with this line of code in sub main, it throws an exception when Form2
closes. It does seem to work OK with a simple example however. Maybe it's
one of the controls that I have on my Form1 such as splitter bar, panel,
toolbar, listbox, treeview, etc. Anyway, I'll live with out VisualStyles for
now until I get time to see exactly what's casuing the error.
Sub Main
Application.Ena bleVisualStyles
Form1.Show
Application.Run ()
end Sub

My WinForms application can have any number of top level forms open at a given time. If the user selects File|Exit, all of the forms are closed. The loop to close the forms looks something like this:
foreach(MyForm form in AllMyForms){
form.Close();
}
Application.Exit();
The OnClosing method is overridden in MyForm. If the user has made changes to his form, this method asks him if he'd like to:
a) save his changes
b) forget changes...

Simple version of the question.....
How do I use the where clause of the open form command to show an

Eg. I select a record on a continuous form and click and edit button.
The button runs the open form code. I want the APPID of the current
