We can even access Microsoft Windows command prompt also known as MS-DOS from QTP interface.cmd.exe is a 32-bit command prompt used in Windows NT, 2000 and XP and offers disk and file maintenance functions as well as network functions. It can be found under System32 folder.

To launch cmd.exe from QTP write :

SystemUtil.Run  “cmd.exe”, “”, “c:\WINDOWS\system32”,”open”

Once DOS window launches, this window can be leant and added to object repository

To write on command prompt window use the following code:

Window( “object class:=ConsoleWindowClass”).Type “Ping crestechsoftware.com”

Window( “object class:=ConsoleWindowClass”).Type micReturn

Using WshShell object

The WshShell object gives your scripts the ability to work with Windows shell .Your scripts can use the WshShell object to perform a number of system administration tasks, including running programs, reading from and writing to the registry, and creating shortcuts.

Following are the list of few methods used with wcript object:

1)The Environment property helps in getting  environment variables

2)The Exec method returns a WshScriptExec object, which provides status and error information about a script run with Exec along with access to the StdIn, StdOut, and StdErr channels. The Exec method allows the execution of command line applications only.

3)Pop Up Method Displays text in a pop-up message box.

4)RegRead Method helps in reading from registry

Example

The following example demonstrates the basics of the Exec method.

Dim WshShell, oExec

Set WshShell = CreateObject(”WScript.Shell”)

Set oExec = WshShell.Exec(”calc”)

Do While oExec.Status = 0

WScript.Sleep 100

Loop

WScript.Echo oExec.Status
