WshScriptExec 對象

說明

可執(zhí)行程序在完成運行時設(shè)置退出代碼。它在過程結(jié)束時傳遞狀態(tài)信息。通常，它用于將錯誤代碼（或某些其他信息段）發(fā)送回調(diào)用方。如果過程仍未完成，ExitCode 屬性返回 0。ExitCode 返回的值取決于所調(diào)用的應(yīng)用程序。

下面的代碼示例 ExitCode 屬性。

[VBScript] 
Dim WshShell, oExec
Set WshShell = CreateObject("WScript.Shell")
Set oExec    = WshShell.Exec("%comspec% /c dire")

Function ReadAllFromAny(oExec)

     If Not oExec.StdOut.AtEndOfStream Then
          ReadAllFromAny = oExec.StdOut.ReadAll
          Exit Function
     End If

     If Not oExec.StdErr.AtEndOfStream Then
          ReadAllFromAny = oExec.StdErr.ReadAll
          Exit Function
     End If
     
     ReadAllFromAny = -1
End Function

Dim allInput, tryCount

allInput = ""
tryCount = 0

Do While True

     Dim input
     input = ReadAllFromAny(oExec)

     If -1 = input Then
          If tryCount > 10 And oExec.Status = 1 Then
               Exit Do
          End If
          tryCount = tryCount + 1
          WScript.Sleep 100
     Else
          allInput = allInput & input
          tryCount = 0
     End If
Loop

If oExec.ExitCode <> 0 Then
     WScript.Echo "Warning: Non-zero exit code"
End If

WScript.Echo allInput
[JScript] 
var WshShell = new ActiveXObject("WScript.Shell");
var oExec    = WshShell.Exec("%comspec% /c dire");

     if (!oExec.StdOut.AtEndOfStream)
          return oExec.StdOut.ReadAll();

     if (!oExec.StdErr.AtEndOfStream)
          return oExec.StdErr.ReadAll();
     
     return -1;
}

var allInput = "";
var tryCount = 0;

while (true)
{
     var input = ReadAllFromAny(oExec);
     if (-1 == input)
     {
          if (tryCount++ > 10 && oExec.Status == 1)
               break;
          WScript.Sleep(100);
     }
     else
     {
          allInput += input;
          tryCount = 0;
     }

     WScript.Echo("Warning: Non-zero exit code");
}

WScript.Echo(allInput);
