描述:
看了MSDN上文章,BHO能够相应IE的事件，但是没有提到怎么用BHO控制IE的界面。我也看到过控制浏览器界面的文章，但都是关于WebBrowser控件的，不知道用BHO能不能实现？？？
解决方案1:
怎样用VC调用IE浏览器并定制右键的快捷菜单?
找一下IDocHostUIHandler::ShowContextMenu
The WebBrowser Control gets its shortcut menu resources from Shdoclc.dll. That knowledge and a few #defines gives you a chance to manipulate the browser's menu. Let's say for instance that you're happy with the default menu, except for the View Source option, which you'd like to eliminate. The following code loads the WebBrowser Control shortcut menu resource from Shdoclc.dll, chooses the correct menu for the context, removes the menu item corresponding to the IDM_VIEWSOURCE command, then displays the menu.
Hide Example
HRESULT CBrowserHost::ShowContextMenu(DWORD dwID,
POINT *ppt,
IUnknown *pcmdTarget,
IDispatch *pdispObject)
{
#define IDR_BROWSE_CONTEXT_MENU 24641
#define IDR_FORM_CONTEXT_MENU 24640
#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"));
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;
}
