there are two client applications running in Win XP, one of them built with VB 5 and the other wint Java 1.4. What mechanism do you recommend to exchange data between these apps ?
The chunks of data are small (max 1k), and the operation is synchronous; the VB app triggers the “request” and the Java one responds to it.
I’d probably go for creating a simple TCP/IP server in the Java app and have the VB app connect to it and send the data when needed.
In VB6 you can use the WinSock control and I assume that this would be available for VB5 as well.
