Communication between applications

Hello NG,

I need to order application #1 to close itself from application #2.

In old Windows NT4, 95 and 98 I used Call SalSendMsg( SalNumberToWindowHandle( -1 ), AM_MyOrderToKill, 0, 0 ) but now it doesn't work anymore.

I can't use SalAppFind since the application I want to kill is in the Hashtray and therefore not visible.

Can anyone give me a push?

Thanks in advance

Hi
There are several methods

1. Tell app#2 the windowhandle from app#1 as a program parameter, then you
can Post (Not send) messages from #2 to #1 as many as you like
2. Good old DDE - You have to use the Windows API, because SALDDE functions
have been dumped
3. System Synchronization Objects (Semaphores, Events - You have to use the
Windows API
4. Named Pipes, Sockets, ... but the effort is worth only, if you require
lots of data exchange

Good luck
Günther
