¿Cómo automatizar el cambio de un componente por otro?

[engranaje]

No tengo experiencia al respecto, siento no serte de ayuda, ya digo para eso uso Gexperts: http://www.gexperts.org/tour/index.h...omponents.html.

En delphi 5 también uso cnpack que tiene herramientas como el "Open High Version Forms Tool" :

Welcome to Open High Version Forms Tool!

Forms in Delphi/C++Builder 6 and above used UTF8 to save AnsiStrings and WideStrings, if DFM files includes SCB case characters, it can not opened in Delphi/BCB 5, even if saved to text format.
This wizard can convert both text and binary format of high version forms.
You can use it to open high version forms directly. Notice: corresponding units will be opened again, so remember to save the unit before re-opening if changes are made.
