That is what the dwData member of the COPYDATASTRUCT structure is for. You can place your own unique 32-bit identifier in that field. When you receive the message, check the value of the field before doing anything with the data. If the message is now yours, then pass it on to the default message handler. > is this a user-only message or is it used for other purposes as well? The VCL uses that message internally for some of its own internal work, which is why you should pass the message on for default handling if it is not your own message. Gambit
