[Antonio Linares]

David,

Solo has cambiado eso en samples\TestRtf.prg ?

Aqui funciona correctamente con ese cambio. Abrimos multiples ventanas MdiChild, las cerramos una a una, todas, y no aparece ningún error

Antonio,

Tan sólo ese cambio. De hecho he descomprimido de nuevo el directorio \Samples por si hubiese hecho algún cambio en testrtf.prg y no lo recordase y comentando esa línea me da el error. Pongo aquí el código de testrtf.prg que viene en \Samples por si hubiese algún cambio, pero vamos, está recien descomprido:

Antonio,

¿Es posible que el foro tenga algún tipo de problema con la longitud del post y los modificadores para resaltar la nomenclatura?. El código anterior si le pongo los modificadores para que quede el texto resaltado, etc. aparece totalmente en blanco.

Saludos!

David,

Puedes descargar mi EXE de tu nuevo ejemplo desde aqui:
http://www.mediafire.com/download.php?e1dvj24byym

Aqui en Windows 7 funciona bien

[triumvirato]

Antonio,

Tu .exe aquí va parfecto. Mismo equipo, mismo todo.

Saludos!

[Antonio Linares]

David,

Es dificil determinar que pueda estar fallando en tu EXE.

Lo idóneo sería que te actualizases a la versión más reciente de FWH para que así estemos usando el mismo software

[triumvirato]

Antonio,

Tu EXE va bien en XP, Vista y Windows 7, el mío en ninguno, así que imagino que sea la versión de FiveWin.
Respecto de actualizar ya sabes que no soy partidario de ir muy atrasado en versiones y ya tocaba hace tiempo, así que en breve lo haremos. Espero que eso además, corrija este fallo.

Saludos!

[Armando]

D. Antonio:

Preguntonta; un texto creado con TRichEdit puede almacenarse en un campo MEMO sin perder sus características ?

Saludos

[Antonio Linares]

Armando,

En principio si, porque salvas el contenido como fichero RTF (ascii) que puede guardarse y luego recuperarse

[Armando]

Maestro:

Si entiendo bien, no puedo guardar y salvar el texto en un campo memo de una DBF (Tal vez un campo BLOB ?),
necesariamente debo guardarlo en otro archivo fuera de la DBF, es correcto ?.

Saludos

[Antonio Linares]

Armando,

Al ser texto ascii deberías poder salvarlo en un campo memo sin problemas

[Armando]

Antonio:

Muchas gracias. Ahora ya voy con paso firme.

Saludos
