Nach Exit-Statement .Net Framework Fehler

Frage

Anmelden

Hallo liebe Community

Ich habe ein Script erstellt, das Fenster mit Windows Forms erstellt. Mithilfe des Exit-Statements möchte ich mein Script beenden. Nach Aufruf erscheint aber folgender Fehler:

Unhandled exception has occurred in a component in your application. If you click Continue, the application will ignore this error and attempt to continue. 

System error.

Hier das Details-Fenster zu der Fehlermeldung:

See the end of this message for details on invoking 
just-in-time (JIT) debugging instead of this dialog box.

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.

For example:

<configuration>
    <system.windows.forms jitDebugging="true" />
</configuration>

When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.

Wie schon gesagt tritt der Fehler immer dann auf, wenn ich das Exit-Statement verwende. Hier ein Beispiel aus meinem Code:

$ListThemesWindow.Dispose()
$Global:SourcePath += $this.Name + "\"
Invoke-Expression -Command  ($this.Text+"Window")
Exit

Nach dem Exit folgt dieser Fehler. Meine bisherigen Problemlösungsversuche:

.Net Framework deinstalliert und wieder installiert
.Net Framework auf Version 4.7 angehoben

Mein System:

Windows Server 2012 R2 Standard
Powershell Version 5.0
.Net Framework 4.7
Aktuellster Patchstand
8 GB RAM
Intel I5 6500

Falls wer einen Lösungsvorschlag hat, ich bin offen für sehr viel.

Vielen Dank

Dispose veranlasst die Form, sich natürlich zu zerstören.
Allerdings darfst du das erst, wenn du die Form verlassen hast, sonst kommt es zu Zugriffen auf das zerstörte Formular. D.h., der Dispose erfolgt erst nach ShowDialog().
Wenn du dann den nächsten Ordner anzeigst kannst du das 1. Fenster nicht enfach zumachen.
Das 2. Fenster kannst du dann ebenso per ShowDialog mit Parent des 1. Fensters anzeigen.
Wenn du dies nicht möchtest, kannst du die Position des Formulars in einen unsichtbaren Bereich (z.B. -32000) einfach verschieben und hinterher wieder zurückstellen.
Bedenke, dass durch das Event-System ein Callback in dein Script erfolgt.
Du musst also warten, bis der Anwender das Kreuz oben rechts (falls sichtbar) drückt oder einen Close-Button hinzufügen.
Der Close mit anschließendem Return (der auch fehlen kann) schließt das Formular und kehrt ins Script zurück.

Da du externe Ressourcen verwendest musst du diese erst wieder freigeben.
Bei Form-Objekten reicht i.d.R. ein Close, der Dispose ist hierfür nicht nötig.
Von der Stackfolge sehe ich nur, dass du wohl auf Grund des OnClick-Ereignisses, dass innerhalb der Form auftritt, die Anwendung beendest.
Hier solltest du dann Close aufrufen und dann in das Script zurückkehren.

Das wäre ja sonst vergleichbar, als wenn du während der Fahrt im Auto einfach die Zündung abstellst.

Noch etwas Hintergrund zu meinem Code, ich bin dran, so etwas wie ein Wiki zu erstellen. Mit der SourcePath-Variable gebe ich den Anfangspfad an. Das Script liest dann die darunterstehenden Ordner aus und gibt sie als Buttons auf einer Form an. die index.txt Datei beinhaltet z.B. eine Überschrift. Wenn ich dann auf einen dieser Buttons drücke, gehe ich in einen Ordner hinein und gebe mit einer weiteren Form an, was sich dort an Ordner etc. befindet. Damit das erste Fenster verschwindet, muss ich Dispose() verwenden, mit Close() funktioniert es nicht.

Ich hoffe so ist es etwas klarer.

Dispose veranlasst die Form, sich natürlich zu zerstören.
Allerdings darfst du das erst, wenn du die Form verlassen hast, sonst kommt es zu Zugriffen auf das zerstörte Formular. D.h., der Dispose erfolgt erst nach ShowDialog().
Wenn du dann den nächsten Ordner anzeigst kannst du das 1. Fenster nicht enfach zumachen.
Das 2. Fenster kannst du dann ebenso per ShowDialog mit Parent des 1. Fensters anzeigen.
Wenn du dies nicht möchtest, kannst du die Position des Formulars in einen unsichtbaren Bereich (z.B. -32000) einfach verschieben und hinterher wieder zurückstellen.
Bedenke, dass durch das Event-System ein Callback in dein Script erfolgt.
Du musst also warten, bis der Anwender das Kreuz oben rechts (falls sichtbar) drückt oder einen Close-Button hinzufügen.
Der Close mit anschließendem Return (der auch fehlen kann) schließt das Formular und kehrt ins Script zurück.
