Hola amigos del foro:
Alguno de ustedes podría orientarme sobre ¿cómo agregar un registro en txbrowse sobre una dbf en blanco?
La idea es utilizar exclusivamente txbrowse sin ningún diálogo o gets externos.
El siguiente es el último código, (lo he intentado de diferentes maneras pero no logro hacerlo). Agradeceré mucho su ayuda.
