Accessing Files and I/O Functions

Overview

Sometimes using Rapise you need to access files on the Windows filesystem, either for testing purposes, or to object test data stored in a flat CSV, TSV or text file. This sample illustrates how you can access the File System using Rapise and the Windows FileSystemObject (http://msdn.microsoft.com/en-us/library/aa242706(v=vs.60).aspx).

Code Sample

The following sample code illustrates how to access files using Rapise:

function Test()

{

  //IOMode constants

   var IOMode_ForReading = 1;

   var IOMode_ForWriting = 2;

   var IOMode_ForAppending = 8;

  //var Format constants

   var IOFormat_ASCII = 0;

   var IOFormat_Unicode = -1;

   //This sample demonstrates how to manipulate the Windows file system using Rapise

   //We shall open a text file for writing in this simple example

   var fso = new ActiveXObject('Scripting.FileSystemObject');

   var ts = fso.CreateTextFile('C:\\Temp\\MyTestFile.txt');

   ts.Close();

   var file = fso.GetFile('C:\\Temp\\MyTestFile.txt');

   ts = file.OpenAsTextStream(IOMode_ForWriting, IOFormat_Unicode);

   ts.WriteLine('Hello World!');

   ts.Close();

   Tester.Message('Wrote File');

   //Now read this file back

   file = fso.GetFile('C:\\Temp\\MyTestFile.txt');

   ts = file.OpenAsTextStream(IOMode_ForReading, IOFormat_Unicode);

   var text = ts.ReadLine();

   Tester.Message(text);

   ts.Close();

}
