I'm confused. Delving into the CMemFile code, it looks like the internal CMemFile buffer is NULL, which means that (memory shortage problems aside) the rich edit control has never called the callback to write to the file. It might be worth putting a breakpoint before the offending line and taking a look at the memFile member variables to see if there is indeed a valid looking buffer in there! If there is no buffer, it could be down to where you are calling the function from - could it be at a point where the rich edit control might have already cleared down the content and started destroying itself? Just out of interest, what did you set GETCONTENT_BUFFER to? I set it to 4096. Sorry I can't be any more help!

The determination of which type of call is being received (fax, modem, or phone) is done in hardware by the modem. Fax and modem calls use different tones to initiate the connection, while phone calls use no tones. The modem card itself detects this, and identifies the type of call in a status register. Check the Platform SDK for TAPI functions to monitor the modem status and the tones received. You may have to resort to writing your own driver if the software that comes with the modem is inadequate. Word of the day: Rotundacrat Extra Credit will be awarded for: Quasimobo...

Aren't you a little bit offtopic here ? Try this one. God luck, And I swallow a small raisin.

TAPI only handles the telephony call handling, answering the call and dropping the call. The actual data sending and receiving isn't handled by TAPI. You have to do this bit yourself. The Platform SDK has the Windows FAX API, I don't know if this is of any use to you. There are third party components that will do faxing using TAPI.

I only want the total of printed pages. Ex: My program will start automatically every time Windows loads. During the Windows session, when user print his/her documents, my program will show the total of printed pages and the total cost of them. Here is an output example: Print time: 12:22:00 Document: letter.doc Cost per page: 5 Total page(s): 3 Total cost: 15
