Syntax
'Declaration
Public Overrides Function ToString As String
'Usage
Dim instance As Process
Dim returnValue As String
returnValue = instance.ToString

Rückgabewert
Der ProcessName kombiniert mit dem ToString-Rückgabewert der Basiskomponente.
Ausnahmen
| Ausnahmetyp | Bedingung |
|---|---|
ToString wird unter Windows 98 nicht unterstützt. |
Beispiel
Im folgenden Beispiel wird eine Instanz von Editor gestartet. Anschließend werden in dem Beispiel verschiedene Eigenschaften des zugeordneten Prozesses abgerufen und angezeigt. Im Beispiel wird festgestellt, wann der Prozess beendet wird, und der Exitcode des Prozesses wird angezeigt.
