sorry becoz i hav to type in english. im using DELPHI and API to write a fax program, where FAXSERVER and FAXDOC is involved. i found this information at windows MSDN.(http://msdn.microsoft.com/library/default.asp?url=/library/en-us/fax/faxlegacy_0oc2.asp) the example of program can be found at http://delphi.ktop.com.tw/topic.php?topic_id=49985. I was tring to write a Delpgi NT service to create a Thread, as i want the program to run at the at the server at all time, without interference of user. the problem that i faced now is that when ever the program run til "AFax.Send", the program will hang, no error message, and any other reaction. anyone has any idea for such program? anyone has any opinion? or anyone has other solution to create a NT Service fax program? thx. and sorry bcoz i hav to type in English.
