如果用户输入了错误的主机名。我希望脚本显示一个msgbox" PC wmi已损坏或处于脱机状态"它会出现错误,但是当它被发送给其他人时,我就像一个基本的错误信息框

下一个包含正确error handling的代码段可以提供帮助:

Sub WindowsLoad1
    strHTML = strHTML & "<br>" & "<font face='Arial' size='2' color='white''>"
    strComputer = MachineName.Value
    strHTML = strHTML & "<b>Sys Info</b><br>&nbsp;<br>"
    strHTML = strHTML & "</font><font face='Arial' size='2'>"
    On Error Resume Next
    Set objWMIService = GetObject("winmgmts:{impersonationLevel=impersonate}!\\" _
             & strComputer & "\root\cimv2")
    If Err.Number = 0 Then
      On Error Goto 0
    Else
      msgbox "Data for current computer displayed due to the error: " _
          & Err.Description _
        , vbOKOnly + vbExclamation _
        , "An error occured"
      On Error Goto 0
      strComputer = "."
      MachineName.Value = strComputer
