system shut down problem with webbrowser

[mikelostcause]

Is there anyway to hold the base.WndProc(re f m) until after the Logout()
function finishes loading a webpage??

I'm working on shutting down an app that runs in the system tray, I have no
problems shutting down, but I have problems saving data first.

if the base.WndProc(re f m) is placed at the top, it closes, but the system
does not continue to shutdown and it does not save the data via the Logout()
funtion.
If the base.WndProc(re f m) is placed at the bottom, it closes correctly, but
doesn't seem to perform the Logout function, I don't believe that it is
waiting for the webpage to load.

protected override void WndProc(ref Message m)
{
//base.WndProc(re f m); ----------placed at the top position
switch(m.Msg)
{
case WM_SYSCOMMAND:

switch(m.WParam .ToInt32()){

case SC_SCREENSAVE:
Logout();
break;

case SC_MONITORPOWER :
Logout();
break;

default:
break;
}
break;

case WM_QUERYENDSESS ION:
this.flagBoolea n1 = true; //do i really want to shut down?
Logout();
break;

case WM_WTSSESSION_C HANGE:
this.flagBoolea n1 = true; //do i really want to shut down?
Logout();
break;

}
base.WndProc(re f m); // placed at the bottom position
}

the Logout() function consists of a call to a website.

my understanding of messages is not very good, and i haven't been able to
find a good way to learn about them.

Mike,

I don't think it should really matter where you place it, because
windows is going to wait for your method to return, and calling the base at
any point isn't going to force the return.

Rather, I would look at the Logout function. Is it loading the page
asynchronously? If so, have it take a flag as a parameter which causes it
to load synchronously, or wait after the call to Logout (through an Event or
something of that nature) to determine when the page is done loading.

Also, what are you using to load the page?

Hope this helps.
