Autor: Michael
// Der Quellcode wurde von NicoDE (nico@bendlins.de) geschrieben.
{
Diese Funktion schreibt alle Informationen über den in Edit1.text angegeneben NT
Prozess (ProzessID) in das Feld Memo1.
}
{
This function write all nt process informations into memo1. In Edit1 you can
specify the processID.
}
