Delphi XE3 third party VCL components in the XE4?

Question

I use Delphi XE3 and I want to migrate to the Delphi XE4. Can I use the same third party components as I used in XE3 in XE4? In previous versions happened many changes, which precluded the use of previous versions of third party components.

Answer 1

You must re-compile your project in XE4, using XE4's VCL.

If by "XE3 VCL" you are actually referring to third-party VCL components, then they need to be compiled and installed in XE4 before they can be used in XE4 projects.

This is true of just about every Delphi version (D2007 being the only exception, as it was binary compatible with D2006).
