Question

我正在使用此article中的代码来自定义Web浏览器的上下文菜单。

但是当我运行此代码时

HRESULT CBrowserHost::ShowContextMenu(DWORD dwID,
                                     POINT *ppt,
                                     IUnknown *pcmdTarget,
                                     IDispatch *pdispObject) 
{
   #define IDR_BROWSE_CONTEXT_MENU  24641
   #define SHDVID_GETMIMECSETMENU   27
   #define SHDVID_ADDMENUEXTENSIONS 53

   HRESULT hr;
   HINSTANCE hinstSHDOCLC;
   HWND hwnd;
   HMENU hMenu;
   CComPtr<IOleCommandTarget> spCT;
   CComPtr<IOleWindow> spWnd;
   MENUITEMINFO mii = {0};
   CComVariant var, var1, var2;

   hr = pcmdTarget->QueryInterface(IID_IOleCommandTarget, (void**)&spCT);
   hr = pcmdTarget->QueryInterface(IID_IOleWindow, (void**)&spWnd);
   hr = spWnd->GetWindow(&hwnd);

   hinstSHDOCLC = LoadLibrary(TEXT("SHDOCLC.DLL")); //here the exception is raised

   if (hinstSHDOCLC == NULL)
   {
       // Error loading module -- fail as securely as possible.
       return;
   }

   hMenu = LoadMenu(hinstSHDOCLC,
                    MAKEINTRESOURCE(IDR_BROWSE_CONTEXT_MENU));

   hMenu = GetSubMenu(hMenu, dwID);

   // Get the language submenu.
   hr = spCT->Exec(&CGID_ShellDocView, SHDVID_GETMIMECSETMENU, 0, NULL, &var);

   mii.cbSize = sizeof(mii);
   mii.fMask  = MIIM_SUBMENU;
   mii.hSubMenu = (HMENU) var.byref;

   // Add language submenu to Encoding context item.
   SetMenuItemInfo(hMenu, IDM_LANGUAGE, FALSE, &mii);

   // Insert Shortcut Menu Extensions from registry.
   V_VT(&var1) = VT_INT_PTR;
   V_BYREF(&var1) = hMenu;

   V_VT(&var2) = VT_I4;
   V_I4(&var2) = dwID;

   hr = spCT->Exec(&CGID_ShellDocView, SHDVID_ADDMENUEXTENSIONS, 0, &var1, &var2);

   // Remove View Source.
   DeleteMenu(hMenu, IDM_VIEWSOURCE, MF_BYCOMMAND);

   // Show shortcut menu.
   int iSelection = ::TrackPopupMenu(hMenu,
                                     TPM_LEFTALIGN | TPM_RIGHTBUTTON | TPM_RETURNCMD,
                                     ppt->x,
                                     ppt->y,
                                     0,
                                     hwnd,
                                     (RECT*)NULL);

   // Send selected shortcut menu item command to shell.
   LRESULT lr = ::SendMessage(hwnd, WM_COMMAND, iSelection, NULL);

   FreeLibrary(hinstSHDOCLC);
   return S_OK;
}

引发此错误

"The specified module could not be found"

我在我的系统上搜索（Windows 7 x64，IE9）并且我找不到SHDOCLC.DLL文件，问题是在IE的新版本中存在任何替换此文件的问题，或者我必须使用其他方式加载上下文菜单并自定义它？

Answer 1

您不应再使用或依赖Internet Explorer的内部资源。正如你在文章中所述，你已经指出：

在Internet Explorer 7中，用于覆盖上下文菜单的技术来自DocObject主机与Internet Explorer 6相同;然而主机必须实现自己的菜单资源。内部资源不应使用Internet Explorer，因为它们可能会更改或移动（如已在Internet Explorer 7中完成。

Answer 2

如果Windows版本比VISTA（包含）更新，请尝试使用LoadLibrary（“IEFRAME.DLL”）。
