Example


In This Topic
    ExtendSelectionRect Method (IIbmScreen)
    In This Topic
    Selects a block of text in the terminal window that includes all rows between the starting row and the specified row.
    Syntax
    'Declaration
     
    
    Sub ExtendSelectionRect( _
       ByVal row As Integer, _
       ByVal column As Integer _
    ) 
    'Usage
     
    
    Dim instance As IIbmScreen
    Dim row As Integer
    Dim column As Integer
     
    instance.ExtendSelectionRect(row, column)
    void ExtendSelectionRect( 
       int row,
       int column
    )

    Parameters

    row
    The row in which the selection should end.
    column
    The column in which the selection should end.
    Exceptions
    ExceptionDescription
    This exception is thrown if the row or column parameters are outside the range of valid values: (1 to Rows) or (1 to Columns).
    Remarks

    Use the SetSelectionStartPos method to set the starting coordinates. (The default is row 1, column 1.)

    The ExtendSelectionRect method returns a rectangular block of text between the starting and ending row, resulting in a block of text shaped like this:

    xxxxxxxxxxxxxxxxxxxx

    xxxxxxxxxxxxxxxxxxxx

    xxxxxxxxxxxxxxxxxxxx

    The ExtendSelection method returns all text in the terminal window between the selection start position and the specified coordinates, resulting in a block of text shaped like this:

    xxxxxxxxxxxxxx

    xxxxxxxxxxxxxxxxxxxx

    xxxxxxxxxxxxxxx

    If the ending coordinates are smaller than the starting coordinates, the ExtendSelectionRect and ExtendSelection methods select text backwards (from right to left or bottom to top).

    These methods select text but do not return the selected area. To get the selected region and its properties, use the ScreenRegion object.

    Example
    This sample selects a block of text when a new screen is ready. It also gets the selected screen region.
    static void screen_NewScreenReady(object sender, EventArgs e)
    {
        IIbmScreen screen = (IIbmScreen)sender;
     
        //Select a block of text
        screen.SetSelectionStartPos(5, 5);
        screen.ExtendSelectionRect(21, 21);
     
        //get the selected screen region object.
        Attachmate.Reflection.Emulation.IbmHosts.IScreenRegion screenRegionIBM;       
        screenRegionIBM = screen.Selection;
        Console.WriteLine("start row = " + screenRegionIBM.StartRow + ", end row = " + screenRegionIBM.EndRow + 
            ", selection mode = " + screenRegionIBM.CurrentSelectionMode );
    }
     
    //Attach the event handler to the IbmScreen object's NewScreenReady event,
    //where ibmScreen is an instance of IbmScreen.
    screen.NewScreenReady += new EventHandler(screen_NewScreenReady);
