GetMessage/SendMessage

[jbonwell]

I have 2 VB apps that I want to be able to communicate to each other. I have a sending exe and a receiving exe. I'm using the SendMessage on the sending exe and the GetMessage on the receiving exe, but not sure what's missing in the middle. I'm using FindWindow to get the handle. I can send a WM_CLOSE command. Just can not figure out how to send any kind of text commands.

its for sending numbers

That's what I meant. I'm just trying to create a way of having one VB app send some kind of command to another VB app. Once the receiving app gets that command, it would performs some function.

Use WM_COPYDATA:

Sorry, couldn't find an example in VB.
