BUG: "Error LNK2001" Error Message When You Call SHGetImageList on a Windows XP-Based System (316931)

RESOLUTION

To resolve this issue, use the LoadLibrary and GetProcAddress functions to call the SHGetImageList function by ordinal. The SHGetImageList ordinal is 727. For this particular case, the ordinal can be counted on to not change across operating system versions, but do not assume this to be true for any other application programming interface (API) unless specifically noted.

The following code demonstrates how to call SHGetImageList by ordinal:

typedef HRESULT (STDMETHODCALLTYPE *SHGETIMAGELIST)(int, REFIID, void **);


STDAPI CallSHGetImageList(int iImageList, 
                          REFIID riid, 
                          void **ppv)
{
   HINSTANCE hinstShell32 = NULL;
   SHGETIMAGELIST pfn = NULL;
   HRESULT hr = S_OK;
   LPTSTR lpszLibPath = NULL;
   TCHAR tchBuffer[MAX_PATH*2];  
   lpszLibPath = tchBuffer; 

   GetSystemDirectory(lpszLibPath, MAX_PATH+1);  
   strcat(lpszLibPath, _T("\\SHELL32.DLL"));

   hinstShell32 = LoadLibrary(lpszLibPath);

   if (NULL == hinstShell32)
   {
         DWORD err = GetLastError();
         return HRESULT_FROM_WIN32(err);
   }

   // 
   // First, try to call the function by name.
   // 
   pfn = (SHGETIMAGELIST)GetProcAddress(hinstShell32, 
                                        (LPCSTR)"SHGetImageList");
   if (NULL == pfn)
   {
      //ONLY if the preceding call fails, try to call the function by ordinal 
    pfn = (SHGETIMAGELIST)GetProcAddress(hinstShell32,
                                           (LPCSTR)727);
      if (NULL == pfn)
      {
         hr = HRESULT_FROM_WIN32(GetLastError());
      }
   }

   if (NULL != pfn)
   {
      // 
      // Call the function.
      // 
      hr = (pfn)(iImageList, riid, ppv);
   }

   FreeLibrary(hinstShell32);
   return hr;
}
