These are the ways that data can be transferred from one
application to another. These are methods of wxConnection.
- Execute: the client calls the server with a data string representing
a command to be executed. This succeeds or fails, depending on the
server's willingness to answer. If the client wants to find the result
of the Execute command other than success or failure, it has to explicitly
- Request: the client asks the server for a particular data string
associated with a given item string. If the server is unwilling to
reply, the return value is NULL. Otherwise, the return value is a string
(actually a pointer to the connection buffer, so it should not be
deallocated by the application).
- Poke: The client sends a data string associated with an item
string directly to the server. This succeeds or fails.
- Advise: The client asks to be advised of any change in data
associated with a particular item. If the server agrees, the server will
send an OnAdvise message to the client along with the item and data.
The default data type is wxCF_TEXT (ASCII text), and the default data
size is the length of the null-terminated string. Windows-specific data
types could also be used on the PC.
