cmd.StandardInput.WriteLine("blaaaaa");// notepad.exe's mem goes to 2000+ kb
cmd.StandardInput.WriteLine("blaaaaa");// notepad.exe's mem goes to 3000+ kb
cmd.StandardInput.WriteLine("blaaaaa");// and finally notepads window shows up

//if i want to start visualstudio form cmd by writing to its input stream i have to write 5+ lines to //the stream
