Buenos días foro, tengo un problema con combos desde código incrustado en un dialogo. El único ejemplo que hay en samples es combos.prg pero faltaba el combos.ch, he cogido un combos.ch que tenía por ahi con esta estructura:

Code: Select all Expand view RUN: #define ID_SIMPLE 110 #define ID_DROPDOWN 120 #define ID_DROPDOWNLIST 130 #define ID_SELECTION 140

suponiendo que esto está bien, cuando compilo el combos.prg, los elementos de los combos NO me aparecen aunque si los selecciono si cambian.

Reitero si me podeis poner un ejemplo manejando combos en dialogos, pero NO desde recursos.

Muchas Gracias a todos.

Mike,

Aqui tienes un ejemplo:

Code: Select all Expand view RUN: #include "FWCE.ch" function Main() local oDlg, cValue DEFINE DIALOG oDlg TITLE "Combos" ; SIZE 200, 100 @ 1, 1 COMBOBOX cValue ITEMS { "One", "Two", "Three" } OF oDlg ACTIVATE DIALOG oDlg CENTERED return nil

Ups!

Me sale exactamente igual que en el ejemplo. Me pinta el combo se despliega pero está vacío

Estoy compilando con FWPPC 8.10, este es mi buildce.bat

Lo unico que he modificado es que la función FW_ANSITOWIDE no la encontraba y la he sustituido por ANSITOWIDE.

De esta forma, la unica diferencia que veo con antes (aunque he visto que la clase internamente tiene varios cambios) es que sale por defecto en azul el combo y que se expande menos posiciones.

Muchas Gracias

Mike,

El tamano lo puedes establecer con:

@ ..., ... COMBOBOX ... SIZE nAncho, nAlto

Entonces, te ha funcionado bien ?

Ya hize los cambios y lo curioso es que algunos combos si los abre y otros no.
Veo en el foro que han tenido problemas con los combos y el nuevo windows mobile 6.1

Por eso preguntaba si alguien tiene el último build y el windows mobile. Que pueda decirme si los combos funcionan correctamente.

Gracias
Fernando
