While I don't work with TAPI 3.x particularly using TAPI 3 from .NET has
many problems.

Refer to the Microsoft KB article ""841712 - Telephony Application
Programming Interface (TAPI) functionality is not supported from managed
code"

But I found example all written by C++. I just want to see some code in C#.
That mean i don't have to write dll from C++, but directly from C#
Thanks

the question is that :
From the example in Platform SDK is written by C++.
I just want to find the exactly the same type of this example but written
by C#. But for the reason that tapi is not supported by .net. So my way is to
write something for Tapi to work well with .NET
Am i right ??
If yes, what kind of thing i will write ?? dll ?

Vuong,
you may want to take a look at Helen's C# wrapper.
See my TAPI and TSPI FAQ:
Q: Are there any .NET wrappers for TAPI2 available ?
http://www.i-b-a-m.de/Andreas_Marschall's_TAPI_and_TSPI_FAQ.htm#_Q:_Are_there_4

[Vuong]

Following Microsoft : You can call TAPI 3.x (Tapi3.dll) functionality from
unmanaged code. Create an unmanaged DLL that calls TAPI 3.x functionality,
and then call the unmanaged DLL from managed code.
And following Helen Warn : when try to use Tapi 3.x with C#. It doesn't
work well.
I'm just confused !!!! Anyone try this !!!

[Vuong]

Yes, this C# wrapper is for Tapi2. And I mention about Tapi3.
Because I want to use Tapi3 for my project. Following Helen Warn, it
doesn't work well with .Net. I just wonder why ? Does anyone try this ?

Following Microsoft : You can call TAPI 3.x (Tapi3.dll) functionality from
unmanaged code. Create an unmanaged DLL that calls TAPI 3.x functionality,
and then call the unmanaged DLL from managed code.

It makes me confuse when to use Tapi3.

[Vuong]

The question is : "Does Tapi3 work well with .Net ?". It make me confuse.

You Can program TAPI 3.x in .net and specially C# and the proof is my
example in VB.net
and here is the url: http://www.vbcity.com/forums/topic.asp?tid=88933

Whatever. Bottom line is many users have reported issues (search this NG)
and MS specifically says it won't hold up, i.e.:

KB article 841712 "Because of the complexity of the TAPI 3.x Component
Object Model (COM) interface, the managed wrapper that is created by
Microsoft Visual Studio .NET does not work. Therefore, you cannot call TAPI
functionality from managed code."

I originally tried using Tapi 3 from .NET. My program worked for awhile,
then suddenly I started to run into horrendous problems. Finally a support
call to Microsoft convinced me that my options were either to (i) write a
RCW for Tapi 3 (they offered to publicize it widely if I did) or (ii) use
Tapi 2. I chose the latter.

Cheers,

Helen

Does anybody know of Microsoft is going to support TAPI from managed .NET
code in the near future? Since the current COM wrapper does not work, will
it be dropped from Visual Studio 2005, or will a new version be released?

Thanks!

Eric,
AFAIK it is currently not planned to support TAPI from managed .NET code.
