[Snipped] Add-In Express ADXOlExplorerCommandBar / CommandBarEvents

Hallo Community,

hier ein kleines Codesnipped für Add-In Express ADXOlExplorerCommandBar.
Folgendes Problem soll damit behoben werden, ADXCommandBarControl's bieten zum Teil nur Events an wie z.B. beim ADXCommandBarButton nur der Klick oder beim ADXCommandBarPopup sogar gar keine Events an.

Um dieses Problem zu beheben, habe ich eine kleine Komponente geschrieben.
Evtl. kann diese noch jemand gebrauchen. Die Komponente kann auch beliebig dann noch durch hinzufügen bzw. abfangen der Windowsnachrichten erweitert werden.

Hiwneis:

  • Es wird AddinExpress dafür benötigt! Die Events können über den Designer herkömmlich über das Event Symbol via doppelklick automatisch hinzugefügt werden, dazu einfach die Komponente auf den Designer ziehen.

Hinweis:
Das snipped kann noch verschönert werden, aber ist im derzeitigen Zustand Funktionsfähig. Man kann den Weg den ich gegangen bin auch verwenden und ein Control ADXCommandPopup (Custom) zu erstellen und z.B. auch Bilder zusätzlich vom Menüpunkt hinzuzufügen - was standardmäßig ja nicht geht. Hierzu einfach den Weg über WindowsNative gehen ähnlich wie bei diesem Snipped.

Anwendungsbeispiel:
Clickevent für z.B. ADXCommandBarPopup mit verhindern des aufklappen der

Menüleiste.
Erst nach Dialogabfrage == true wird dann ein aufklappen der Menüleiste möglich.

/Ps
Habe es nicht unter Snipped gestellt da es eher um Office Anwendungen geht. Falls es doch an der falschen Stelle sein sollte, entschuldige ich mich jetzt schon mal dafür.

Viel Spaß damit!
