csv - 我需要将VBS WScript.Echo输出写入文本或cvs

Question

我正在尝试编写一个VBScript，它将以文本文件或csv的形式列出系统上所有已安装的应用程序。我能够找到一个列出所有软件的现有代码(包括名称，版本，日期和大小)。当我当前运行它时，我发现它随着主机回显弹出而出现回显。我需要在vb中添加什么以使其将每个回显输出到文件？我确信这很容易，但是我似乎找不到解决方案。

以下是我找到的脚本:

Dim fso
Set fso = WScript.CreateObject("Scripting.Filesystemobject")
' List All Installed Software





Const HKLM = &H80000002 'HKEY_LOCAL_MACHINE
strComputer = "."
strKey = "SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\"
strEntry1a = "DisplayName"
strEntry1b = "QuietDisplayName"
strEntry2 = "InstallDate"
strEntry3 = "VersionMajor"
strEntry4 = "VersionMinor"
strEntry5 = "EstimatedSize"

Set objReg = GetObject("winmgmts://" & strComputer & _
 "/root/default:StdRegProv")
objReg.EnumKey HKLM, strKey, arrSubkeys
WScript.Echo "Installed Applications" & VbCrLf
For Each strSubkey In arrSubkeys
  intRet1 = objReg.GetStringValue(HKLM, strKey & strSubkey, _
   strEntry1a, strValue1)
  If intRet1 <> 0 Then
    objReg.GetStringValue HKLM, strKey & strSubkey, _
     strEntry1b, strValue1
  End If
  If strValue1 <> "" Then
    WScript.Echo VbCrLf & "Display Name: " & strValue1
  End If
  objReg.GetStringValue HKLM, strKey & strSubkey, _
   strEntry2, strValue2
  If strValue2 <> "" Then
    WScript.Echo "Install Date: " & strValue2
  End If
  objReg.GetDWORDValue HKLM, strKey & strSubkey, _
   strEntry3, intValue3
  objReg.GetDWORDValue HKLM, strKey & strSubkey, _
   strEntry4, intValue4
  If intValue3 <> "" Then
     WScript.Echo "Version: " & intValue3 & "." & intValue4
  End If
  objReg.GetDWORDValue HKLM, strKey & strSubkey, _
   strEntry5, intValue5
  If intValue5 <> "" Then
    WScript.Echo "Estimated Size: " & Round(intValue5/1024, 3) & " megabytes"
  End If
Next

一种解决方法是通过cscript.exe运行脚本并将输出重定向到文件:

cscript.exe //NoLogo "C:\path\to\your.vbs" >"C:\output.txt"

如果要修改脚本以将其输出写入文件，而不考虑其运行方式，则需要添加代码以打开/关闭输出文件:

Dim fso
Set fso = WScript.CreateObject("Scripting.Filesystemobject")
Set f = fso.OpenTextFile("C:\output.txt", 2)

...

f.Close
'End of Script

并将每次出现的 WScript.Echo替换为 f.WriteLine。
