All applications are written in Visual c++, OS is XP home. Is it possible to send a message over the network to the Watchdog app to instruct it to reset the remote PC? Will FindWindow() work over a network (using the IP afddress of the remote machine), or is there another way of getting the handle of the Watchdog application? for IPC over network, there are very few method available one of them is SOCKET, Remote Procdeure Call and NamedPipes( i havn't used Named pipes over network). but Socket is most easy way to communicate over network!

Do you really want to wade through several thousand items in the listbox? Why not create a circular list (i.e., older items get replaced by newer items) that only holds a small amount of items? The listbox could then show the contents of this list. "The greatest good you can do for another is not just to share your riches but to reveal to him his own." - Benjamin Disraeli

But be careful if you are looking for changes on remote (network) shares. Both ReadDirectoryChangesW(...) and FindFirstChangeNotification(...) may experience problems when working with network shares - regarding path lengths and/or the remote system might not support notification of filesystem changes in such a manner. (Experienced this myself more than one time.)    IOW, if your application could be working with remote filesystems, it should have a polling interval as a fallback as well.  Nothing worse than getting a call first thing in the morning from a site saying that your "real-time file processing application" stopped working this morning (they upgraded a *nix box that hosted one of the shares used the previous evening, and its network file support was slightly broken).    Peace! -=- James If you think it costs a lot to do it right, just wait until you find out how much it costs to do it wrong!

Your a Star! I have just tried that and it works - simple! Thank you very much Mike

Thanks Ryan, I think that has sorted it! Mike

Hi Khan++ Thanks for your help - yep thats got it now! Thanks again Mike

You don't happen to be trying to run the debug version, are you? I had that problem too, saying such and such dll was not found, when I realized I was compiling in debug. If you compile in release (if this is your problem) that problem should go away. Hope this helps! Danny The stupidity of others amazes me!
