Hola.
¿Cómo averiguo cuáles son la primera y la última filas pintadas en un xBrowse?
Me gustaría, por ejemplo, poder escribir el mensaje: Mostrando resultados 7 al 29 de un total de 50
y que éste se actualizara al navergar por el xbrowse.
Por supuesto, no deseo agregar una nueva columna mostrando ::bKeyNo
Gracias.
¡Salud y saludos!

nFirstKeyNo := oBrw:KeyNo() - oBrw:nRowSel + 1
nLastKeyNo := nFirstKeyNo + oBrw:RowCount() - 1
In case of RDD, nFirstKeyNo and nLastKeyNo are the OrdKeyNo() of the first and last records displayed.
In case of Array, nFirstKeyNo and nLastKeyNo are the first and last array elements displayed. In case of RecoreSet they are AbsolutePostion of the first and last rows.

Please reconsider. There will be hundreds of such requirements for various purposes. Should we keep modifying the main class for each such requirement? Will there be ever an end for it? Can we not make do with functions?
What makes a good case for modifying a class is when the class itself has to know these datas or methods for its own working.
Just my personal opinion.
