lineCallbackFunc not returning message..... [modified]

[AmbiguousName]

hello guys...everything seems to be fine here but when I call at my landline number it does't show me the number. TapiInitialize()

void WINAPI TapiInitialize() {

LPLINEDEVCAPS lineDevCaps = NULL;
lineDevCaps = (LPLINEDEVCAPS)LocalAlloc(LPTR, 4096);

//create the event first..
EventReply = CreateEvent(NULL,FALSE,FALSE,NULL);

//clear the structure before the usage
memset(&LineInitializeExParams,0,sizeof(LINEINITIALIZEEXPARAMS));

//populate the options
LineInitializeExParams.dwTotalSize = sizeof(LINEINITIALIZEEXPARAMS);
LineInitializeExParams.dwOptions = LINEINITIALIZEEXOPTION\_USEEVENT;

//call the LineInitializeEx function
result = lineInitializeEx(&lineApp,NULL,(LINECALLBACK)&lineCallbackFunc,NULL,&numDevs,&tapiVersion,&LineInitializeExParams);
if (result!=0)	
	printf("TAPI could't be Initialized"); 
else printf("\\n\\nTAPI Initialized..");

num = numDevs;
printf("\\nNumber of lines available to this app:  %d",(LPWSTR)num);

result = lineNegotiateAPIVersion(lineApp,0,API\_EARLY\_VERSION,API\_CURRENT\_VERSION,&tapiVersion,0);
result = lineGetDevCaps(lineApp,0,tapiVersion,0,lineDevCaps);
//opening a line
result = lineOpen(lineApp,0,&hLine,tapiVersion,0,0,LINECALLPRIVILEGE\_MONITOR,LINEMEDIAMODE\_DATAMODEM,NULL);
if(result!=0)
	printf("\\nLINE could't be Opened...");
else
	printf("\\nLINE Opened...");

TapiShutDown()

void WINAPI TapiShutdown() {
result = lineShutdown(lineApp);
if (result==0)
printf("Line closed successfuly");
else
printf("something went wrong");
}

and lineCallbackFunc().

VOID FAR PASCAL lineCallbackFunc(DWORD hDevice,DWORD dwMsg, DWORD Param1, DWORD Param2, DWORD Param3) {
if (dwMsg == LINE_REQUEST)
printf("incomg line...");
}

In the main(), I just call these functions.

int _tmain(int argc, _TCHAR* argv[])
{
TapiInitialize();
Sleep(180000);
printf("\n\nPress any key to close line....");
getche();
TapiShutdown();
return 0;
}

Where am I doing something wrong??:confused:

You can look at these : [^] http://tapifaq.pennypacker.org/tapifaq3.html[^] Answering machine(TAPI 2.1)[^] Though the answer doesn't address your issue directly .. they might give u a proper direction. -Kushagra

You need to open a TAPI-device before you can receive any events - use lineOpen. Most likely you will wan't to preceede that with lineNegotiateAPIVersion and lineGetDevCaps.

Do any of the printf() statements work?
