Bug in the framework?

[Wayne]

Running V1.1 with latest SP (1 right?), on Windows XP. I have the following
in a web service:

[WebMethod()]
public Double Factorial(int n )
{
double n1 = 1;
double result = 1;
while (n1 <= n)
{
result = result * n1;
n1 = n1 + 1;
}

System.Threading.Thread.Sleep(10000);

return result;
}


In my client Code I have under a button click:
MessageBox.Show(CSService.Factorial(20).ToString());

When the messageBox displays the main form is still selectable, I can click
items on the form, close the form etc...

If I put the sleep down to 100 the messagebox is displayed modally. I know
the example is unlikely that you would do something like this, but what if
the web service really takes this long? Also if I call the web service as
Async I see the same issue when the messagebox gets displayed.

haven't run the code you included below but aren't we at SP2 as the
atest? -hazz

Just ran a quick search on Microsoft's site and all I found was SP2 for 1.0,
not for 1.1.

Well I actually got it narrowed down some more. It has nothing to do with
the web service. It is just the windows form application.

Drop a timer on the form, set it's interval to 1000 and put this in for the
timer event:

timer1.Enabled = false;
MessageBox.Show("TEST");


Run the application and make sure to take focus away from the form/App. I
just select my News reader. Once you do this and the message box displays
the form is selectable.

Wayne,

If you change that to

MessageBox.Show(this, "TEST");

you will see the correct behaviour.

[Wayne]

Cool, but shouldn't it still work either way? I mean if the form never loses
focus it works just fine. I will defiantly keep this in mind for later
reference.

Also with the way it works if you don't pass "this" you can close the form,
leaving the message box, and closing the message box afterwards leaves the
application running.

[Joakim Karlsson]

Hmm...

MessageBox.Show internally calls the private MessageBox.ShowCore method.
This method checks the owner window passed to it. If this method is
null, it uses the active window as parent and calls the native
MessageBox function.

Does seem a bit strange. Perhaps you should post this on a winforms
group instead. Maybe someone there can shed some light on this.

"If this method is null, " should of course read "If the owner window is
