lineProxyMessage
The lineProxyMessage function is used by a registered proxy request handler to generate TAPI
messages related to its role. For example, an ACD agent handler can use this
function to generate LINE_AGENTSTATUS messages that will be received by all applications that have the specified
line open. TAPI suppresses generation of the message on the hLine specified in the function parameters.
LONG lineProxyMessage(
HLINE hLine,
|
| HCALL hCall,
|
| DWORD dwMsg,
|
| DWORD dwParam1,
|
| DWORD dwParam2,
|
| DWORD dwParam3
|
| );
|
|
Parameters
hLine
A handle to the open line device. This will be converted by TAPI into the
correct hLine for each application that receives the message.
hCall
If the message is related to a specific call (which it is not, in the case of
LINE_AGENTSTATUS), specifies the proxy handler's handle to that call; shall be
set to NULL for messages not related to a specific call. This will be converted
by TAPI into the correct hCall for each application that receives the message.
dwMsg
The TAPI message to be generated. This must be a message that is permitted to
be generated by proxy handlers.
dwParam1
dwParam2
dwParam3
The parameters associated with the message to be sent.
Return Values
Returns zero if the function is successful or one of these negative error
values:
LINEERR_INVALLINEHANDLE, LINEERR_INVALCALLHANDLE, LINEERR_INVALPARAM,
LINEERR_NOMEM, LINEERR_NOTREGISTERED, LINEERR_OPERATIONFAILED,
LINEERR_OPERATIONUNAVAIL, LINEERR_RESOURCEUNAVAIL, LINEERR_UNINITIALIZED.

Nostalgia .Net |

.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. Net classes. More » |
