Trying to extract different types of data from a singe file.

I am trying to create a windows program that reads binary graphics as
a resource. This has nothing to do with win32 but conversion of data
with memcpy.

graphic::graphic(UINT uiResID, HINSTANCE hinstance){
   size = 32;
   bitData.clear();
   void * p = NULL; // point to the data
   int end;
   BYTE data;

   static HGLOBAL hglob;

   HRSRC hRes =
     FindResource(hinstance,MAKEINTRESOURCE(uiResID),TEXT("BINARY"));

   if(hRes){
     hglob = LoadResource(hinstance,hRes);
     p = LockResource(hglob);
     memcpy((int*) &end, p, sizeof(int)); // puts the first but of
data to int.

     for(int lp = 0; lp != end; lp++){
       bitData.push_back(0);
     }

     for(int lp = 0; lp != end; lp++){
       memcpy((BYTE*) &bitData[lp], p, sizeof(BYTE)); puts the rest
of the data in BYTE type.
      }

  }
   set();
   create();
}

My question is how do I extract each but of data from p first to the
int type with is the number of data bits then each bit of data to put
into my bitData vector. I can't increase the pointer p++ to get to
the next bit of data. This compiles and runs but does not extract the
data for me.
