Ich gehe durch diesen Code und kann es nicht wirklich knacken. Bitte helfen Sie mir, ich versuche eine Datenbankverbindung zwischen zwei Dateien zu bekommen und bekomme immer einen Fehler beim ersten Code in Zeilen, die mit // Connect to Client Database beginnen und ich kann es nicht herausfinden. Ich habe mehrere verschiedene Wege ausprobiert über dieses Problem zu gehen.DB Verbindungsproblem
dies ist der k_dbfunctions Code
