Hello all,

I've been busy lately with reading the tapi.hlp file, and especcialy the
part on Caller-ID, and this is what i've found out until now:

My app needs to be able to receive messages from tapi, and especcialy
LINECALLSTATE_OFFERING messages. But here's my first problem. How do i do
this? What i've read is that you have to do it with phoneSetStatusMessages.
And if this is true, how do i get the hPhone handle which is needed in the
function? and another problem with phoneSetStatusMessages:
which dwPhoneStatus should be enabled for me to be able to receive
LINECALLSTATE_OFFERING messages?
Some sample code for Delphi would be really cool.
So when i receive an offering message, i need to check the dwParam1 to see
what's happening... and then with LineGetCallInfo(dwDevice,
LPLINECALLSTATUS) i need to get the caller-id?
I know that i can get the dwDevice-handle from the LINE_CALLSTATE message,
but what is LPLINECALLSTATUS about? What does it do? What do i need it for?
How do i use it?
In the help file they say that it's a pointer to a variable of type
LINECALLSTATUS, but since i'm an absolute beginner and my english isnt good
enough (i think), i dont know what they're saying... or meaning...
Again, some sample code would be usefull.
And ofcourse, the age old question: Is this it, or is there more to it?

Please help me out, i've looked at several components on several
delphi-pages, but none of them actually worked, so please no more pointers
to web-pages, cuz until now what i found there hasn't been of any use to me.

Thnx a lot in advance!

Grtz
StefanMelis

ps i'm working in delphi 3 client server, and am connected via serial port
to an Alcatel telephone, i'm using TAPI version (i dunno, i believe 1.3 or
1.4)...  And for the dutch people: Sorry datie in't Engels is, maar had
weinig tijd om naar Nederlands terug te vertalen. Mijn excuses!

  There is sample TAPI delphi code at:

  http://www.delphimag.com/features/1999/11/di199911re_f/di199911re_d.asp

  It demonstrates the use of "callbacks" in delphi, which appears to be
  your main problem.

~ > ps i'm working in delphi 3 client server

  Unfortunately that code is written for D4 and makes extensive use of
  DWORD, so you will not be able to use it without modification.

  Just to point you a bit;

    the main callback routine there is:  LineCallBack(...)


Which is defined as follows (in that code):

  ErrNo := LineInitialize(
           @rTapi.hTapi,        // Usage Handle (other TAPI functions need).
           MainInstance,        // TAPI.DLL stores info here (can forget).
           rTapi.pLineCallback, // Function windows will call with msgs.
           '',                  // Optional app name. (for LINECALLINFO).
           @rTapi.dwNumDevs);   // # of devices(modems/virtual) returned here.

  rTapi.pLineCallback is a pointer to the LineCallBack(...) function.


  I will not be able to give you much additional help, since that
  program was my first and last effort with both DELPHI and TAPI.


  Good Luck;
