Certainly! It's important to consider the file format you're localizing, as this can impact the process. For instance, standard Windows resources offer flip and mirror capabilities for entire dialogs, while .NET WinForm dialogs provide the ability to mirror specific controls. When the dialog editor is opened you will find the Flip menu in the ribbon.

Please also note that this just covers the dialogs, while mirroring the complete application frame main window is another thing.

That's a real quick solution for my a week problem!

Btw I would love to know more about this, since I have more than 180 dialogs to flip.

Usually, not all controls in a dialog must be mirrored. If it contains picture controls, you must flip them back. This, and the fact that different resources (Standard, Delphi, .NET) have different methods, is why there is no automated feature to flip all dialogs. 

But the internal data to flip a dialog is accessible using the object model and one can implement a macro to flip all dialogs in a project for a specific language. Otherwise I would suggest flipping them manually.
