Syntax

'Declaration
Public Overrides Sub DisplayTextAt ( _
    row As Integer, _
    column As Integer, _
    data As String _
)

public override void DisplayTextAt (
    int row,
    int column,
    string data
)

public:
virtual void DisplayTextAt (
    int row, 
    int column, 
    String^ data
) override

public void DisplayTextAt (
    int row, 
    int column, 
    String data
)

public override function DisplayTextAt (
    row : int, 
    column : int, 
    data : String
)

Parameters

• row
  The start row for the text.

• column
  The start column for the text.

• data
  The string of characters to display.

Remarks

The characters in data are processed beginning at the window location specified by the row and column parameters, and continuing in succeeding columns.

If the CapBlink property is set to NoBlink, all blink escape sequences will be filtered out for purposes of display. If the CapReverse property is set to None, all reverse escape sequences will be filtered out.

DisplayTextAt has the same effect as setting the CursorRow property to row, setting the CursorColumn property to column, and then calling the DisplayText method.

The LineDisplayBase class ensures that the line display device has been opened, claimed, and enabled.

DisplayTextAt may throw a PosControlException with the following ErrorCodes:

Value	Meaning
Illegal	One or more of the following conditions has occurred:The value specified for row or for column is out of range; orDisplayText can’t be called when the device is in Marquee On Mode.
