Para Eduardo Morcillo (Editor de tipos)

19/02/2005 - 18:10 por Pedro Rivera | Informe spam

Eduardo Morcillo: Gracias por explicarme cómo hacer el
editor de tipos en Visual Basic .Net. Llevaba un buen
tiempo buscando la manera y de no ser por ti, así
estuviera todavía: Buscando.

Ya logré hacer que se muestre el editor y funciona casi a
la perfección, el casi es que no logro hacer que recuerde
su valor. Por ejemplo, la estructura tiene dos
propiedades que son Entero y Cadena cuyos valores
iniciales son 0 y "", si le asigno valores de 33 y "Mi
Nombre" respectivamente en la ventana de propiedades, y
después cierro la solución, al abrir nuevamente la
solución, los valores son 0 y "".

Por último, una pregunta: ¿Tomaste un curso con
Microsoft, trabajas(te) para ellos o dónde conseguiste
toda esa información que tienes sobre VB Net?
Te dejo el código de lo que estoy haciendo por si es que
puedes ayudarme otra vez.
