Syntax

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

public abstract void DisplayTextAt (
    int row,

    int column, 
    String^ data
) abstract

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

public abstract 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 that is 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 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.

DisplayTextAt may cause a PosControlException to be thrown with the following ErrorCode.

Value

Meaning

Illegal

One or more of the following conditions has occurred:

  • The value specified for row or for column is out of range.

  • The window is in Marquee On mode, and DisplayTextAt cannot be called while the device is in that mode.
