AtEndOfStream Property (Windows Script Host)

Returns a Boolean value indicating whether the end of an input stream has been reached.

                      object.AtEndOfStream 

Arguments

  • object
    StdIn text stream object.

Remarks

The AtEndOfStream property contains a Boolean value indicating whether the end of an input stream has been reached. The AtEndOfStream property returns True if the stream pointer is at the end of an input stream, False if not. The StdIn, StdOut, and StdErr properties and methods work only when the script is run with CScript.exe. If the script is run with WScript.exe, an error occurs.

Example

The following code samples demonstrate the AtEndOfStream property by reading a standard directory listing from "dir", stripping the top and bottom lines that aren't actual entries, and double spacing the directory entries.

Dim StdIn, StdOut, Str1, Str2

Set StdIn = WScript.StdIn
Set StdOut = WScript.StdOut

Str1 = ""
Str2 = ""For i = 0 to 4 
   StdIn.SkipLine
Next

i = 0
Do While Not StdIn.AtEndOfStream
     If i >= 2 Then
          StdOut.WriteLine Str1
     End If
     i = i + 1
     Str1 = Str2
     Str2 = StdIn.ReadLine
Loop
var stdin = WScript.StdIn;
var stdout = WScript.StdOut;
var str1, str2 = "";
var i;
for (i = 0; i < 5; i++)
     stdin.SkipLine();
i = 0;
while (!stdin.AtEndOfStream)
{
     if (i++ >= 2)
     {
          stdout.WriteLine(str1);
     }
     str1 = str2;
     str2 = stdin.ReadLine();
}
