我的印象是这是不可能的,但这就是我到目前为止所得到的。

Sub Main()        
    On Error GoTo ErrorHandler        
    If Command$ = "" Then
        LogAction "Begin document lockdown"
        LockdownDocs
        LogAction "Lockdown complete"
    Else
        LogAction "Begin document enabling"
        EnableDocs
        LogAction "Documents have be enabled"
    End If
Exit Sub
ErrorHandler:
    LogAction "DocLock Error " & Err.Number & "::" & Err.Description
End Sub

我希望它看起来像这样:

Function Main() As Boolean
    On Error GoTo ErrorHandler        
    If Command$ = "" Then
        LogAction "Begin document lockdown"
        LockdownDocs
        LogAction "Lockdown complete"
    Else
        LogAction "Begin document enabling"
        EnableDocs
        LogAction "Documents have be enabled"
    End If
    Return True
Exit Function
ErrorHandler:
    LogAction "Error " & Err.Number & "::" & Err.Description
    Return False
End Function

我见过的最接近的是Function Main() As IntegerVisual Studio 2005,但我使用的是 VB6。

这里有一个可能的解决方案,通过使用 Win32 API 调用。本质上:

Private Declare Sub ExitProcess Lib "kernel32" (ByVal uExitCode As Long)

' Exit with ErrorLevel set to 9
ExitProcess 9

请注意,这相当于EndVB 运行时,因此您必须在调用ExitProcess.
