Re: ITBasicCallControl2 does not have CreateTerminal function

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

Thanks,
The examples which use createTerminal dont work on my notebook. (Outgoing
and tapisend). I dont know why but theres got to be a reason. I spent a lot
of time on them and more or less understood whats going on in those codes.
But since sample codes dont work on my notebook, I didnt think its a very
good idea to write any other code based on them. Can you confirm that
tapisend and outgoing works on Windows XP ?(If so, I will try to borrow
another pc (not easy) and try them on those)
So as you said I modified the fileterm since it works fine on my laptop. It
uses requestTerminal. Thats why I insisted on using requestTerminal.
Honestly I am neither a programmer nor interested in telephony applications.
(I kinda started to get interested though) I am developing video processing
applications for security systems for my advisor and he told me to add
telephone, fax, e-mail, etc... properties to the system to notify the users.
I didnt have any problem with other things (like fax, etc). But this Tapi
3.1 is the worst documented thing I have ever encountered in microsoft
libraries. I am kinda disappointed with microsoft, too. They are always
bragging about the support they provide(I dont see any microsoft people
here), there were lots of people which helped me on Linux forums while
developing similar things. There are some errors in the sample codes on the
msdn. they might seem like simple mistakes for experienced programmers but
It makes the situation pretty hard for beginners. Especially since
experienced users advise us to look at those wrong codes which makes us
think that they are true but we just dont get it. Since there are lots of
things we really dont get , we cant trust our own judgements till we improve
our knowledge on the subject. Anyways, Is there any book related to Tapi 3.1
or tutorial you know ? Especially I prefer e-books. This is not gonna work
with MSDN, thats for sure. I have less than 5 days to finish the whole
project. So if you know any code(which works) that makes a call and plays a
sound file that would be great, too, Sorry for the stupid questions but I am
working on 10 different microsoft libraries now and its not easy.

Thanks again.
