I am trying to navigate an IVR via TAPI on windows ce, I am able to use the
lineGenerateDigits API call, but am running into a buffer limitation that I
cannot get more than 14 digits pulsed out at once. What I would like to do
now is try the following from a previous post:

"To send DTMF tones during the call, you should post the
WM_CPROG_SEND_VKEY_DTMF message to the CProg window. The CProg window can be
found by looking for a window with class "MSCprog". The message is defined in
\public\shellw\oak\inc\wpcpriv.h. The WPARAM for the message should be a
TCHAR representing the DTMF character.

Does anyone know where to get the following file or files?
\public\shellw\oak\inc\wpcpriv.h

Thanks

I am not always successful in using lineGenerateDigits() call. Some devices it works great, others it only works intermittently. I found this post mentioning to send a message to the CPROG window. Does anyone know where WM_CPROG_SEND_VKEY_DTMF is defined or what the value is ?

Thanks
Harry
