ReadAll Method (Windows Script Host)

Returns all characters from an input stream.

Copy


                      object.ReadAll

Arguments

object: StdIn text stream object.

Remarks

The ReadAll method returns a string. The StdIn, StdOut, and StdErr properties and methods work when running the script with the CScript.exe host executable file only. An error is returned when run with WScript.exe.

Example

The following code demonstrates the use of ReadAll.

VBScript

Copy

Dim Input
Input = ""

Do While Not WScript.StdIn.AtEndOfStream
   Input = Input & WScript.StdIn.ReadAll
Loop
WScript.Echo Input

JScript

Copy

var input = "";
while (!WScript.StdIn.AtEndOfStream)
{
   input += WScript.StdIn.ReadAll();
}
WScript.Echo(input);

Applies To:

FAQ

How is the behaviour defined?

Does it behave the same on WScriptExec.StdOut and WScriptExec.StdErr compared to WScript.StdIn?
Does it block if there is nothing to read, or does it return immediately?
If it blocks, how can the user tell in advance whether there is anything to read to avoid blocking?
Does AtEndOfStream tell you if there is anything to read, or does it just tell you when the stream is closed?
