hi Mr Jens here is my source code:
void main(){
MLENV env;
 int error;
  MLINK ml;
   env = MLInitialize(0);

 if(env == (MLENV)0)
   { printf("unable to initialize environment"); }

   ml = MLOpenString(env,"-linkname \"C:\\Program Files\\Wolfram
Research\\Mathematica\\6.0\\MathKernel.exe\" -mathlink",&error);

 if(ml == (MLINK)0 || error != MLEOK)
   { printf("unable to create link to the Kernel"); }

   MLActivate(ml);
   if(!MLActivate(ml))
   { printf("unable to establish communication");}
return ml;
}

}

Thank you.
