I have an old app (Delphi 5) which I want to give it some changes.
I have set a manifest for it, but speedbuttons are not following the Windows theme. What should I do?
Even though this post is not answering directly your question, MAYBE it will help you somehow:
I agree with others that the easy way will be to upgrade to the latest edition of Delphi. However, this is a fast (if you ignore the UNICODE conversion) but not cheap solution. A cheaper solution (and even faster) may be to 'pimp' your application using a Delphi skin package. Your application may look even better than the 'classic' Windows Vista/7 themes.
