See Also                   Applies To


Description
Reads an entire TextStream file and returns the resulting string.

Syntax
object.ReadAll( );

The object is always the name of a TextStream object.

Remarks
For large files, using the ReadAll method wastes memory resources. Other techniques should be used to input a file, such as reading a file line by line.

The following example illustrates the use of the ReadAll method:

function GetEverything()
{
  var fso, f;
  var ForReading = 1, ForWriting = 2;
  fso = new ActiveXObject("Scripting.FileSystemObject");
  f = fso.OpenTextFile("c:\\testfile.txt", ForWriting, true);
  f.Write("Header");
  f.Write("1234567890987654321");
  f.Close();
  f = fso.OpenTextFile("c:\\testfile.txt", ForReading);
  return(f.ReadAll());
}
