Ersten Anzeigenamen von PackageID

Question

Blick durch die Quelle der Anwendung Wix Standard-Bootstrapper, scheint es, dass jedes Paket eine Display Eigenschaft hat:

pPackage->sczDisplayName 

jedoch die BootstrapperCore DLL, die in dem WiX-Setup verwendet wird, Projekt hat diese Eigenschaft nicht. Gibt es eine Möglichkeit, diese Eigenschaft aus den Bundles in verwaltetem Code zu extrahieren?

ich portierte den Bal Code in C#, versuchte, es genau wie der C++ Code zu machen arbeiten:

Answer 2

Die Datei BootstrapperApplicationData.xml, die während des Erstellungsprozesses generiert wird, befindet sich neben Ihrer BA-DLL. Sie können diese XML-Datei laden, um viele Informationen über das Bundle und die Pakete im Bundle zu erhalten.

Um den BootstrapperApplicationData.xml in systemeigenem Code zu laden, verwenden Sie die BalManifestLoad()-Methode in balutil.lib, die mit dem WiX-Toolset bereitgestellt wird. Sie können den Code in src\ext\BalExtension\balutil\balutil.cpp sehen. Dann können Sie BalInfoParseFromXml() auch in balutil.lib verwenden, um die XML-Datei in eine Reihe von handlichen Strukturen zu analysieren. Sie können den Code in src\ext\BalExtension\balutil\balinfo.cpp sehen.
