Sending data over a local area network

[Stopher]

I want to send some data to another computer. Just a few variables, not any large amount of data. Does anyone have any idea how/if I could do this?

Thanx,
Stopher

Hi,
If you have permission to do so, you can just create a flat file on the other computer. Like so:

Open &quot;\\<computername>\<sharename>\<filename.ext>&quot; for output as #1

This syntax is referred to as UNC (Universal Naming Convention)

Good Luck,
Paul

Nah Sir!

That means constantly checking to see if the file has been updated, or indeed exists...

What you really want to do is have a look at a thing called the Winsock control... That is used for passing info between PCs - I once wrote an app for transferring the content a text box on One PC to a textbox on another - and that worked with Winsock...

If I were to use the file method, is there any way of determining the computername and sharename of the other computer?

Yes, but as a professional I really would encourage you not to use the file method... For one thing constantly pinging the hard drive every half second is a bit pointless...

If you use WinSock, you'll get a nice little event to latch onto one a computer tries to send info to you... And I think it stores the hostname that sent the info as a property too!

But, if you'll insist on using files, read about the Windows32 API. There's bound to be a function in their for finding the name of the computer you are on - so have the sending machine build it's name into the text file...

Hope that helped you out...

I'm thinking of using the Winsock method. Does it come with Visual Studio Enterprise edition or will I have to get it somewhere?

You should already have the Winsock Control if you have VS Ent 6...

Press Cntrl-T while in your VB project, and look down the Controls tab for &quot;Microsoft Winsock Control 6.0&quot;

Have a look in the MSDN for details on it's use...

When i run my s/w i want to inform the other computers on the n/w of my ip add. How can I do this without knowing the ip adds of the other comps.
