Hallo,
wir bekommen in einem Kundenprojekt eine Exception vom ListLabelViewerControl. Die Anwendung läuft auf einem Terminalserver. Wenn die Anwendung hier gestartet ist und die Verbindung wird getrennt, erhält man bei erneutem Verbindungsaufbau folgende Exception:

Blockquote
Application: SFM_DashboardApp.exe
Framework Version: v4.0.30319
Description: The process was terminated due to an unhandled exception.

Hat diesen Fall jemand schon mal gehabt? Was können wir hier machen?!

Wir prüfen gerade, ob wir dieses Problem reproduzieren können. Bitte haben Sie etwas Geduld.

Wir konnten das Verhalten nicht nachstellen. Könnten Sie uns bitte im Detail erklären, wie die Anwendung ausgeführt wird (als Remote-App?) und was genau bei dem Trennen der Verbindung passiert bzw. wie diese Verbindung getrennt wird?

Hallo.
Ich konnte das Verhalten auch mit einer Windows 10 VM (Hyper-V) per Remoteverbindung über den Hyper-V Manager nachstellen.

Es handelt sich um eine normale WPF Anwendung. Zum Test habe ich die Views soweit reduziert, dass nur noch das ListLabelViewerControl mit einer statischen Datei geladen wird.

Sobald ich nun die Verbindung trenne (Fenster der Remoteverbindung schließe) und wieder aufbaue, stürzt das Programm kommentarlos ab (lediglich der Stacktrace im Eventlog). Kommentiere ich die Zeile mit dem ViewControl aus, tritt dieses Verhalten nicht auf.

Hallo Dennis,

auch mit dieser Vorgehensweise konnten wir das Verhalten nicht nachstellen.

Um die Ursache für den Absturz genauer untersuchen zu können, benötigen wir eine Dump-Datei. Mittels ProcDump könnten Sie versuchen sich an den Prozess SFM_DashboardApp.exe zu attachen, anschließend die Remote-Verbindung schließen (was dann zum Absturz führt und ProcDump das Dump schreiben lässt) und sich dann erneut verbinden.

ProcDump ist ein Kommandozeilen-Utility und kann wie folgt an den Prozess attached werden:

procdump.exe -accepteula -e -ma SFM_DashboardApp.exe %temp%\crash.dmp 

Die Dump-Datei können Sie uns über das Supportportal hochladen.
