  16. I think the documentation for AfxGetInstanceHandle is wrong when 
  17. using MFC dynamically.
  18.  
  19. My solution is this:
  20.  
  21. class SwitchInstance
  22. {
  23.         HINSTANCE m_hAppInst;
  24.  
  25. public:
  26.         SwitchInstance()
  27.         {
  28.                 m_hAppInst = AfxGetResourceHandle();
  29.  
  30.                 AfxSetResourceHandle(theDll.m_hInstance);
  31.         }
  32.  
  33.         ~SwitchInstance()
  34.         {
  35.                 AfxSetResourceHandle(m_hAppInst);
  36.         }
  37. };
  38.  
  39.  
  40.  
  41. In each exported function I create an instance of 
  42. SwitchInstance.
  43.  
  44. Everything works - magic!
