ITAddressTranslation::get_CallingCards method (tapi3if.h)
The get_CallingCards method creates a collection of calling cards associated with the address. This method is provided for Automation client applications, such as those written in Visual Basic. C and C++ applications must use the EnumerateCallingCards method.
Syntax
HRESULT get_CallingCards(
[out] VARIANT *pVariant
);
Parameters
[out] pVariant
Pointer to VARIANT containing an ITCollection of ITCallingCard interface pointers.
Return value
This method can return one of these values.
| Value | Meaning |
|---|---|
|
Method succeeded. |
|
The pVariant parameter is not a valid pointer. |
|
Insufficient memory exists to perform the operation. |
Remarks
The get_CallingCards method is a COM wrapper for the TAPI 2.2 LineGetTranslateCaps function, and takes calling card information from the LINETRANSLATECAPS structure returned by that function.
TAPI calls the AddRef method on the ITCallingCard interface returned by ITAddressTranslation::get_CallingCards. The application must call Release on the ITCallingCard interface to free resources associated with it.
