Thanks for helping Cool_Dev I did think about doing this in a similar manner - setting a 1 second timer running and checking to see the position of playback to see if the end of file had been reached. It did strike me as being a bit in-elligent. I was hoping for there to be a 'MCI_NOTIFY_PLAYBACK_FINISHED' type of message that I would need to capture. I don't know if you have seen my reply to my own post - I have had some success in getting a message, but I just have the value - it would be nice to know its definition. Thanks for lookingg and your advice Mike

TCP is a connection oriented protocol, the server needs to accept the connection and a handshake is performed before further communication will be possible (which is part of TCP's reliable data transfer). On the other hand, if you are working with UDP, which is not connection oriented, you don't have to call accept(), sockets can just send data when they feel like (which could also mean nobody is listening to them).

The spelling of the function name in GetProcAddress must be exact. You can also try calling GetLastError like this: DWORD Error = 0; DLLFunc = GetProcAddress(hDLL, "MyFunction" ); if ( ! DLLFunc ) Error = GetLastError(); This will tell you the reason that the call failed. You can find out the exported functions inside the DLL, by using the program Dumpbin that comes with the SDK. dumpbin /EXPORTS MyDll.dll

I would also have a look at the articles here on codeproject... (shocking idea, I know...) eg: Limiting an application to a single Instance - the MFC way[^] is a great one. Just read my comments at the end to make it work. Iain. I have now moved to Sweden for love (awwww).

Excellent - thanks very much - using the example got exactly what I wanted! Thanks very much Mike
