Hola gente.
Bueno, para mi proyecto neuvo, nesecito que un form sea transparente pero que los controles ocx sobre el se vean. O sea, imaginen una ventanita con imagenes con pedazos transparentes. Pero ocmo no queda que se vea el fondo del form, nesecito hacerl otransparente; o si saben otra forma de hacerlo, les agradezco.
Saludos
