I have read through the various postings and tried to put some code together but it won't compile.

To start a thread, your handler does

void CMyView::doInvert()
    {
     running = TRUE;
     AfxBeginThread(run, this); // why is a 'this' pointer passed as the pParam?
                                // run is refering to member function 'UINT CMyView::run(LPVOID p)'?
    }
 
UINT CMyView::run(LPVOID p)
    {
     CMyView * me = (CMyView *)p;  //why is 'p' cast from something that already seems to be 
                                   //a CMyView pointer already?
     me -> run();
     return 0;
    }
 
void CMyView::run()  //run is an overloaded function?
   {
     for(int x=y = 0; running && y < image.height; y++)
          for(int x = 0; running && x < image.width; x++)
              changePixel(x, y);
    running = FALSE;
   }
