ExtendSelectionRect Method (IIbmScreen)
Example 


Attachmate.Reflection.Emulation.IbmHosts Namespace > IIbmScreen Interface : ExtendSelectionRect Method
The row in which the selection should end.
The column in which the selection should end.
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
System.ArgumentOutOfRangeException 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);
