XTYP_REGISTER
A dynamic data exchange (DDE) callback function receives the XTYP_REGISTER transaction type whenever a Dynamic Data Exchange Library (DDEML) server application uses the DdeNameService function to register a service name, or whenever a non-DDEML application that supports the System topic is started.
This transaction is filtered if the application specified the CBF_SKIP_REGISTRATIONS flag in the DdeInitialize function.
A application cannot block this transaction type; the CBR_BLOCK return code is ignored.
An application should use the hsz1 parameter to add the service name to the list of servers available to the user. An application should use the hsz2 parameter to identify which application instance has started.
Windows NT: Requires version 3.1 or later.
Windows: Requires Windows 95 or later.
Windows CE: Unsupported.
Header: Declared in ddeml.h.
