Sending messages to other applications is easy. You need to aquire the window handle of the other application window you'd like to send messages to. For example, you can use:

hwnd = FindWindow(NULL, "the title of the window");
if (hwnd != NULL)
PostMessage(hwnd, message, 0, 0);

Or, you can broadcast a message to all windows in the system:

PostMessage(HWND_BROADCAST, message, 0, 0);

Where "message" is either one of the standard messages (WM_xxx) or a user-defined one.

You can define messages for inter-application communications by asking Windows to provide a unique message number:

message = RegisterWindowMessage("Message ID string");

Note that the program that receives the message should now how to deal with it :-)

Is this a satisfactory answer?

Use the Command:

In the Sending Program use
RegisterWindowMessage(..)
and
PostMessage(..)

In the program that must recieve the message use the command
RegisterWindowMessage(..) and wrote a Routine to process the Message.
