Probably the problem is that you need also handle both FindResourceW and
LoadResource failures the same way by returning -1, and change 'return -1;'
later to 'return 0;' (for invalid parent) as MSDN suggests. All that needs
to be tested as well. Also DialogBoxParamW needs to be fixed as well.

Probably other dialaog APIs (like DialogBoxIndirectParamAorW) need a review
regarding that.
