[python-win32] Threads in COM not given time to execute?

[Marcus Low]

Hi,

I am testing a COM component, when i execute it under pythonwin idle and single 
stepping F10 to "SmtpMail.Start()" :

    SmtpMail = win32com.client.Dispatch("SomeSMTPCom")
    SmtpMail.Start()    
    
I can telnet to 127.0.0.1 25 and get a proper SMTP response


But when i run the program it just quits so i am assuming SmtpMail.Start() does 
not block. So i added a function to wait for an event
before allowing the function to quit to that SmtpMail.Start() can run as long 
as it want :-

def MainEntry () :
    global FlagToStop

    SmtpMail = win32com.client.Dispatch("SomeSMTPCom")
    SmtpMail.Start()    
    thread.start_new(CheckForQuit,(0,))
    
    while FlagToStop == False :
        win32api.Sleep(1000)      # i tried os.sleep(0), pass but the uses 50% 
of cpu

    SmtpMail.Stop()
    

i have confirmed that the it will loop in "While FlagToStop ..." however when i 
telnet 127.0.0.1 25, it gets connected but i don't get a reply from the COM 
which
is a STMP component. I can get a response if i use single step to where 
".Start()" but if i just run the program i get this feeling that the COM object 
here doesnt
get the time to execute and thus could not respond.

Am i missing out some basic steps here?


Marcus.
