Propiedades de un SWF en ASP

[Saruman]

hola a todos.... solo era para cooperar con el foro y compartir los conocimientos con los demas....
aqui les dejo una funcion interesante para conseguir las propiedades de un archivo en flash (.swf).

lo unico malo es que funciona bien para las versiones menores a la 6. esto es cuando exportan el archivo desde el macromedia flash le colocan la opcion que diga version y alli colocan una menor a la 6. eso es lo unico malo que encontre del codigo, por lo demas esta excelente.... sacas el ancho, alto, version, framerate, etc. del swf....

aqui esta el codigo.... los tranfsforme a una funcion para mejor facilidad de uso. el mismo tiene un include .inc.

ok


swfheaderdump.inc

Código:

Excelente, solo que para evitar que colaboraciones como esta sean facilmente localizadas (y no se pierdan con el tiempo), te suguiero postearla en las FAQ's.
