ahh i figured what my problem was: I #included the <web/sproc.h>-file and not the <web/web.h>. For some Reason the compiler had problems linking all that stuff...

Here is my code so far:

One<SlaveProcess> pipe;
pipe=StartLocalProcess("pgnuplot");
	
if(pipe){
   pipe->Write("plot sin(x)\n");

   cout<<"running...\n";
   String s;
   Sleep(10000);	
   pipe->Kill();
   cout<<"gnuplot returned: "<<pipe->GetExitCode();
}//*/

I got the problem, that In this code "pipe" is NEVER invalid, as long as I have pgnuplot as starting command. Even if there appears a problem with starting pgnuplot for example, if I use invalid options and similar stuff.

Second Problem is, that for some reason I can not use the Kill()-Command. I am just not able to finish gnuplot when I started it...

Any idea on this?

Greetings, Tom...
