MFC Support that works - Satellite DLLs
Actually, the previous support for MFC (unmanaged C++) projects in the Add-In worked, but it had a serious downside.
There is no easy way to get MFC to load resources in a specific language. The only reliable way is to add extra code to more or less every class which will load resources. The Add-In's help file describes a lot of specific ways to do this for different MFC classes. It's not pretty.
Now I have discovered that newer versions of MFC have support for satellite DLLs. In version 4.7x.0028 I have added support for MFC satellite DLLs. Finally, this is now MFC support which simply works without having to add lots of extra code by hand.
I have tried to describe it in this article, which you can also access via the Articles menu item. I have also updated the Quick tour to refer to MFC satellite DLLs. Unfortunately, it is anything but quick.
Next on the list, is the help file.
