ExitCode Property
Returns the exit code set by a script or program run using the Exec() method.
Object.ExitCode
Parameters
- Object
WshScriptExec Object
Remarks
Executables set an exit code when they finish running. This conveys the status information when a process ends. Often, it is used to send an error code (or some other piece of information) back to the caller. If the process has not finished, the ExitCode property returns 0. The values returned from ExitCode depend on the application that was called.
Example
The following code shows an example of the ExitCode property.
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
var WshShell = new ActiveXObject("WScript.Shell");
var oExec = WshShell.Exec("%comspec% /c dire");
function ReadAllFromAny(oExec)
{
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;
}
}
if (oExec. ExitCode!= 0)
{
WScript.Echo("Warning: Non-zero exit code");
}
WScript.Echo(allInput);
