porting dll from NT to 98 strikes back (FindFirstPrinterChangeNotific)

[moisesventura]

Hi again,

My dll was working perfectly till I run it in 98. I'm trying to detect a document arriving to the printer Q.

First I've used:
hPrinterNotification = FindFirstPrinterChangeNotification(bla,bla,bla)

Works ok (I've checked hPrinterNotification == INVALID_HANDLE_VALUE and it's not)

But in the next step:

DWORD waitingResult = WaitForSingleObject(hPrinterNotification, jWaitingTime);

I receive a waitingResult == WAIT_FAILED with "The handle is invalid. " error.

Some idea? (Note... WAS WORKING IN NT!!!!!!)

dummy problems happens when you don't read carefully the documentation:

Requirements
Windows NT/2000: Requires Windows NT 3.5 or later.
Windows 95/98: Unsupported.
Header: Declared in Winspool.h; include Windows.h.
Library: Use Winspool.lib.

Sorry about that.
