Disculpa nuevamente he tratado de enviarte la hoja que hice con el macro que
me has enviado a esta direccion NOSPAMlapink2000@PLEASEhotmail.com pero me la
ha rechazado varias veces.He hecho todo como dijiste pero al llegar a
presionar Ctrl + F8 no ocurre nada y por lo tanto no se donde hacer
doble-clic sobre "ListPermutationsOrCombinations". La verdad es que no se que
hacer. Te agradeceria si me dieras una direccion donde enviar la hoja. O si
me puedes explicar que hago de mal.
Sinceramente gracias . Max

Hola Max,
Prueba el siguiente macro publicado por Myrna Larson. Lo tienes que
depositar en un modulo VBA. Para ello:
1) haz clic-derecho sobre el nombre de cualquier hoja en una de las pestañas
de la parte de abajo de la ventana de Excel.
2) Elige la opcion Ver Codigo para abrir el editor VBA.
3) Una vez en el Editor VBA, ve al menu Insertar>Modulo
4) En la ventana mas grande a la derecha pega el codigo que te pongo a
continuacion.
5) Ahora en la hoja activa pon lo siguiente:
celda [A1]= C
celda [A2]= 3
celda [A3]= 1
celda [A4]= 2
celda [A5]= 3
celda [A...]= ...
celda [A9]= 7
6) Pulsa Ctrl+F8
7) Haz doble-clic sobre "ListPermutationsOrCombinations"
Saludos,
KL
