Capturar imagenes con Power Builder He aqui un pequeo ejemplo que encontre de como capturar imagenes desde un webcam usando PowerBuilder y Eztwain.Mas info de eztwain y el dll se pueden encontrar en: www.dosadi.com/eztwain1.htmEs una buena idea poner el dll (eztw32.dll) en el folder de la aplicacion y no en el system32 de windows (si se pone en system32 hay que registrar el dll)script:GlobalVariables
