Broadcasting message on a network ???

Mort #1 / 6	Broadcasting message on a network ??? hi I'm about to develop an app which should have the ability to broadcast it's existens on a network on startup. There should be no particular server to broadcast to, but other machines on the network running the app should respond to the broadcast. Is this possible or ??? The app is developed using VB6 enterprise and should communicate using TCP/IP. DCOM is also an option, but I would prefer TCP/IP. Any comments ?? I've found out, that I should use UDP, but an example on how it's implemented would be nice. Any suggestions appriciated... thanx Morten

Bose Jankulovsk #2 / 6	Broadcasting message on a network ??? Try to find this control Cswsk32.ocx. It give u ability to send broadcast message, but if u use broadcast u must use UDP, TCP/IP Doesn't support broadcast( If I'm wrong pls let me know ).

Michel Wals #3 / 6	Broadcasting message on a network ??? Hi, In theory, you can, if you set all the host bits will all 1: 192.168.0.255 will be broadcasted to all PC on the network 192.168.0.0, but there is probably more to just setting that destination address.

Dana Hallenbec #5 / 6	Broadcasting message on a network ??? Are all the computers on the same domain? If so, you could use NetMessageBufferSend and just preset the values you want to remain constant. If you need an example check out: http://www.mvps.org/vbnet/ search for NetMessageBufferSend and you will find the code.

SSarmd #6 / 6	Broadcasting message on a network ??? Hi You can use UDP protocol with winsock.ocx very easily . For example if your address is 200.200.200.1 etc. ( using subbnet 255.255.255.0) you must send UDP messages to 200.200.200.255 and specify a port number. I have tested this but you must know proper subnet in your LAN. If you want write me and I'll send you code. Sincerely , Siamak
