The LINE_REQUEST message is sent to report the arrival of a new request from
another application.
LINE_REQUEST
dwDevice = (DWORD) 0;
dwCallbackInstance = (DWORD) hRegistration;
dwParam1 = (DWORD) RequestMode;

dwParam3 = (DWORD) RequestModeDetail2;
Parameters
dwDevice
Not used.
dwCallbackInstance
The registration instance of the application specified on lineRegisterRequestRecipient.
dwParam1
The request mode of the newly pending request. This parameter uses the
following LINEREQUESTMODE_ constants:
LINEREQUESTMODE_MAKECALL
A tapiRequestMakeCall request.
dwParam2
If dwParam1 is set to LINEREQUESTMODE_DROP, dwParam2 contains the hWnd of the application requesting the drop. Otherwise, dwParam2 is unused.
dwParam3
If dwParam1 is set to LINEREQUESTMODE_DROP, the low-order word of dwParam3 contains the wRequestID as specified by the application requesting the drop. Otherwise, dwParam3 is unused.
Return Values
No return value.
Remarks
The LINE_REQUEST message is sent to the highest priority application that has
registered for the corresponding request mode. This message indicates the
arrival of an Assisted Telephony request of the specified request mode. If dwParam1 is LINEREQUESTMODE_MAKECALL or LINEREQUESTMODE_MEDIACALL, the application can
invoke lineGetRequest using the corresponding request mode to receive the request. If dwParam1 is LINEREQUESTMODE_DROP, the message contains all of the information the
request recipient needs in order to perform the request.

.Net is powerful, but not all-powerful, so sometimes we need to use Win32 API for our .Net applications. It's simple enough with Platform Invoke if you have Win32 skill, but we do not always have time to dig the ancient documentation, declare the special types that are compatible with Win32, find the values of the Win32's constants and so on. Nostalgia .Net offers several simple-to-use classes, and components that will allow you to forget about the headache of Win32 and just use the power of Win32 in your application the same way as you use the native.
