Re: Timer not working in WinCE Service

Tech-Archive recommends: Repair Windows Errors & Optimize Windows Performance

Why do you have a message pump?? You have no windows. You have no
messages. Create a loop with a Sleep of WaitForSingleObject call like Paul
suggested. Asking for help is not terribly useful if you're not going to
listen to the advice given.

here is my message loop code ....

DWORD MyThread(void * f_pMainObj)
{
MSG msg; // message structure

while(GetMessage(&msg, NULL, 0, 0) > 0)
{
TranslateMessage(&msg); // translates virtual-key codes
DispatchMessage(&msg); // dispatches message to window
}
return 0;
}

// and Timerproc
void CALLBACK TimerProc(HWND hwnd, UINT uMsg, UINT idEvent, DWORD dwTime)
{
// Doing some file logging here, to know that control has reached here
return 0;
}

I just want to know that, why timers are not working in case of Service,
but
same DLL is working when not using as service !!!!!!
any clue ..???

Hello Paul,
I used a simple thread to complete my task. But for timers, as u said
there
is no message loop, So I created a simple thread which was having
message
loop to dispatch the messages. But it was not working too.
Now the same code (with timer and without any message loop) for a
simple
DLL
was working but whenever I was registering the same DLL as service, the
code
stops working. I wornder, what is the issue here.

SetTimer() uses, if I recall correctly, the application event loop to
notify
the clients that the timer has fired. Since you're in a driver and
there
is
no message loop, that's not going to work. You'll need to use
something
different. That might be a multimedia timer, if your OS has that, a
simple
WaitForSingleObject() with a timeout equal to 2000, etc.

I am using SetTimer(NULL, NULL, 2000, (TIMERPROC) TimerProc) inside
xxx_Init,
but it seems control is not going my TimerProc.
My Timerproc is as:
void CALLBACK TimerProc(HWND hwnd, UINT uMsg, UINT idEvent, DWORD
dwTime)

What may be the reason that timeer is not working.

Hi,
I am creating a Win32 service for my WinCE 4.2 based device using
eVC++. I
am using timer in that but its not working. But when I run the
same
DLL
no
as
service, it executes fine ....

What may be the problem that time is not working in service?
Please let me know if U have any idea...
Thanks,
Rahul
