Problems with lineGetID()

Hi!

I'm trying to use lineGetID() like this:

int size = sizeof(VARSTRING) + 4;
VARSTRING* vs = (VARSTRING*)new char[size];
vs->dwTotalSize = size;
long r = GetID(NULL, 0, m_theCall, LINECALLSELECT_CALL, vs, "wave/out");

I have also tried:

GetID(m_theLine, 0, m_theCall, LINECALLSELECT_CALL, vs, "wave/out");

and:

GetID(NULL, 0, m_theCall, LINECALLSELECT_LINE, vs, "wave/out"); ...etc.

I get the return value 0x8000042 which is "nodevice".
What am I doing wrong? m_theLine and m_theCall have proper values (I think) from lineOpen etc.
Shall I use LINECALLSELECT_LINE or LINECALLSELECT_CALL for "wave/out" or doesn't it matter?

Maybe someone recognizes the problem!?

I need more information to help diagnose this problem. GetID is not a TAPI function. Show the code you use to invoke the actual TAPI function. Place a breakpoint before that call and examine each parameter. List them (their values going into the TAPI function) here.

You may also need to use:

vs->dwStringFormat= STRINGFORMAT_BINARY;

Sorry.. I forgot to show the function declaration, GetID is just a WINAPI* to lineGetID so I can load tapi.dll instead of using the lib.

Anyway, the problem is now solved. The solution was to 1) use openLine with the LINEMAPPER parameter (this should NOT be necesary but it helped for me)
2) use the parameters GetID(m_theLine, 0, NULL, LINECALLSELECT_LINE, vs, "wave/out");
If I use LINECALLSELECT_LINE it seems like the call parameter must be null.

Thank you for trying to help me anyway!

(PS. I did not have to set vs->dwStringFormat= STRINGFORMAT_BINARY, it works anyway.)
