Tengo el siguiente problema: Utilizo el Microsoft Web Brownser para mostrar direcciones de clientes en los mapas de google. Funciona perfectamente en un proyecto cliente servidor, pero si lo compilo como aplicacion web... ¡Me desconoce el objeto "document"!
Al ejecutarlo me arroja el error "object null"
De hecho, ya trabajando cliente-servidor al escribir: "ole_navegador.Object." al oprimir el operador punto deberia mostrarme el objeto document.... cosa que no hace.
Pongo el codigo completo, que, repito, funciona perfectamente como aplicacion cliente-servidor:
