I'm working with EventHandlers for a menu I've got on my WinForm and I'm trying to follow the Windows example given but my function is returning a bool when the compiler is looking for a 'uint' apparently.

The code windows has:

1
2

    let opExitForm sender args = form.Close ()
    do miQuit .add_Click (new EventHandler(opExitForm))

My code:

1
2
3
4
5
6
7

    let opInternetHelp sender args =  
        let ieProcess = new Process() in
        ieProcess.StartInfo.UseShellExecute <- true;
        ieProcess.StartInfo.FileName <- "http://matt.insidegamer.org/";
        ieProcess.Start();;

    do miOnlineHelp .add_Click (new EventHandler(opInternetHelp))

Is there some kind of like default uint value I can return or some way to modify this function to run correctly?

EDIT: I've added the |>ignore command to the Start() function and that seemed to fix it but it runs terribly slow. Is this the preferred method? And is it slow because of the ignore?
