I have succesfully found out how to use WOL (Wake On Lan) to turn on a computer with Visual Basic.
But this however only works with LAN it seems.
I have tried changing the UDP broadcast subnet from "255.255.255.255" (LAN) to something according to the IP address of the PC I wich to wake up (was told this was possible at www.planetsourcecode.com but could not get it to work)
PLEASE ADVICE!!!!!!!!!!!
broadcast subnet is 255.255.255.0 (or 1)
If I just enter 255.255.255.0 then I can wake up any PC in the world connected to the net just I have the MAC address??
Dont' you dare try mine :D :D :D
Well, give it a shot..
nono, pfef, only on your network!Quote:

Say the computer has IP 1.2.3.4 and is connected to the ISP 24/7 with an always-on ADSL modem.
How should I wake the PC??
Specifying UDP remotehost = "1.2.3.255" or "1.2.3.0" or "1.2.3.1" does not work. Or even "1.2.3.4" does not work...
Please help me on this matter...
Is it limited to LAN?
If yes: why?!? Usually you can send UDP messages to other subnets as well!!
If no: HOW DO I SOLVE THIS PROBLEM????
Can anyone supply me with info/source codes/specific links please???
BTW TennisMan - I don't have your MAC number so don't worry!!
I don't know if this is the answer you're looking for, but most ISP's routers implement a pruning function to kill broadcast messages.
it's been a long time since I posted this thread. And since then I have found a solution.
An ActiveX component from www.ninstall.com that of course can be used both for ASP and VB and so on...
You had the right idea....wrong information. The broadcast address is dependant on the way your ISP assignes addresses.
For example:
My DSL provider has assigned me the following addresses (hypothetically)
64.217.108.0/29 - what this means is that they are applying a 29-bit subnet mask to the class A network address....thus allowing them to break up the class A space into millions of networks.
Therefore...my network is 64.217.108.0....with usable addresses of 64.217.108.1 thru 64.217.108.6....with a broadcast address of 64.217.108.7
Hope this helps....must have a good working knowledge of networking to fully understand subnetting.
