Beispiel: Projektunterstützung

Im folgenden JScript-Beispiel wird gezeigt, wie Sie mit Hilfe der MapForce API komplexe Aufgaben im Zusammenhang mit MapForce-Projekten automatisieren. Stellen Sie vor Ausführung des Mappings sicher, dass der Inhalt der Variablen strSamplePath auf den Ordner MapForceExamples Ihrer MapForce-Installation verweist.

 

Um alle Operationen im nachfolgenden Beispiel erfolgreich ausführen zu können, benötigen Sie die Enterprise Version von MapForce. Wenn Sie mit der Professional Version arbeiten, sollten Sie die Zeilen, in denen das Webservice-Projekt eingefügt wird, auskommentieren.
