Getting command line output in VBScript (without writing to files)
提问by 213897
I'm using VBScript, and my goal is to be able to substitute a drive letter for a path of my choosing. I need the D drive, and if it's not available I need to check if it's already mapped to the right spot; then notify the user if it's not. I found this: http://technet.microsoft.com/en-us/library/ee156605.aspxand I'm trying to adapt their second example:
我正在使用 VBScript，我的目标是能够用驱动器号替换我选择的路径。我需要 D 盘，如果它不可用，我需要检查它是否已经映射到正确的位置；如果不是，则通知用户。我发现了这个：http: //technet.microsoft.com/en-us/library/ee156605.aspx，我正在尝试调整他们的第二个例子：
Set objShell = WScript.CreateObject("WScript.Shell")
Set objExecObject = objShell.Exec("cmd /c ping -n 3 -w 1000 157.59.0.1")
Do While Not objExecObject.StdOut.AtEndOfStream
strText = objExecObject.StdOut.ReadLine()
If Instr(strText, "Reply") > 0 Then
Wscript.Echo "Reply received."
Exit Do
End If
Loop
(my adaptations):
（我的改编）：
Set objShell = WScript.CreateObject("WScript.Shell")
Set objExecObject = objShell.Exec("cmd /c substr")
strText = ""
Do While Not objExecObject.StdOut.AtEndOfStream
strText = strText & objExecObject.StdOut.ReadLine()
Loop
Wscript.Echo strText
Then I'll probably search for the string that tells where the D drive is mapped. I've also tried objShell.Exec("subst"), but I still don't get any output. Does anyone have any ideas on what I might be doing wrong? Or is there a better way to tell about drive mappings? Thanks,
然后我可能会搜索指示 D 驱动器映射位置的字符串。我也试过objShell.Exec("subst")，但我仍然没有得到任何输出。有没有人对我可能做错的事情有任何想法？或者有没有更好的方法来说明驱动器映射？谢谢，

Your script doesn't work because you've mistyped the command name - it's subst, not substr.
您的脚本不起作用，因为您输入了错误的命令名称 - 它是subst，而不是substr。
