You should be able to do something like this (I've done this with
other widgets... but not bitmaps. I'm assuming it'll work with bitmaps
however):

wxXmlResource::Get()->InitAllHandlers();
InitXmlResource();   //Or whatever your xmlresource function is
called  within the dynamically generated cpp file
wxFrame *pMyFrame;
wxXmlResource::Get()->LoadFrame(pMyFrame, NULL,
wxT("The_frames_name"));
wxBitmap *pMyBitmap = XRCCTRL(*pMyFrame, "bitmap_name", wxBitmap);
