  • Working with API functions in QTP

  • Extern object – It enables us to declare calls to external procedures from an external dynamic-link library (DLL).
  • Declare Method - Declares references to external procedures in a dynamic-link library (DLL).
    Once we use the Declare method for a method, we can use the Extern object to call the declared method

    Syntax
    Extern.Declare(RetType, MethodName, LibName, Alias [, ArgType(s)])

    Argument

    Type

    Description

    RetType

    String

    Data type of the value returned by the method.

    MethodName

    String

    Any valid procedure name.

    LibName

    String

    Name of the DLL or code resource that contains the declared procedure.

    Alias

    String

    Name of the procedure in the DLL or code resource.

    ArgType

    String

    A list of data types representing the data types of the arguments that are passed to the procedure when it is called.

    Example
    'Declare FindWindow method
    Extern.Declare micHwnd, "FindWindow", "user32.dll", "FindWindowA", micString, micString
    'Declare SetWindowText method
    Extern.Declare micLong, "SetWindowText", "user32.dll", "SetWindowTextA", micHwnd, micString
    'Get HWND of the Notepad window
    hwnd = Extern.FindWindow("Notepad", vbNullString)
    if hwnd = 0 then
    MsgBox "Notepad window not found"
    end if
    'Change the title of the notepad window
    res = Extern.SetWindowText(hwnd, "qat")


    RegisterUserFunc utility in QTP

  • Enables us to add new methods to test objects or change the behavior of an existing test object method during a run session
  • When we use this statement, QuickTest uses our user-defined function as a method of a specified test object class for the remainder of a run session, or until we unregister the method.

    Syntax
    RegisterUserFunc TOClass, MethodName, FunctionName, SetAsDefault

    Argument

    Type

    Description

    TOClass

    String

    The test object class for which you want to register the method.

    MethodName

    String

    The method you want to register.

    FunctionName

    String

    The name of your user-defined function. The function can be located in your action or in any library file associated with your test or component.

    SetAsDefault

    Boolean

    Indicates whether the registered function is used as the default method for the test object.

    Example
    The following example uses the RegisterUserFunc method to create a new Copy method for the WinEdit test object that copies all the text in an edit box to the Windows Clipboard.
    Sub Copy (edit)
           Edit.Click 3, 3
           Edit.SetSelection 0, Len(Edit.GetROProperty("text"))
           Edit.Type micCtrlDwn + "c" + micCtrlUp
    End Sub

    RegisterUserFunc "WinEdit", "Copy", "Copy"
    ' Now you can call the new method
    Dialog("Login").WinEdit("Agent Name:").Copy
