RunApplication

c++ #

Runs an application and waits for it to return.

Archived content: This source code is currently inactive and may be outdated or no longer maintained or functional.

Ein Prozess ist schnell gestartet. Aber dann auch noch auf dessen Beendigung zu warten und den Rückgabewert auszulesen erfordert im Windows-API schon ein paar weitere Zeilen. Die sind in der RunApplication-Funktion dargestellt.

Note on the code quality: The content on this page is possibly a bit outdated. I’m not using C++ anymore for quite some time, but I would like to keep the existing and once useful functions available.
