IDocHostUIHandler::ShowContextMenu添加自定义菜单的另类实现

这里有两种另类的实现方式：

第一种是使用SetWindowLong，接管WndProc，一切尽在接管之中。

第二种是在自己的程序中添加相应的菜单ITEM，弹出菜单后，接管一些ITEM点击事件。

第二种方法的详细实现：

STDMETHODIMP CMyDocHostUIHandler::ShowContextMenu(DWORD dwID, POINT* ppt, IUnknown* pcmdtReserved, IDispatch* pdispReserved)

{

// 添加扩展菜单

#define SHDVID_ADDMENUEXTENSIONS 53

// 获取编码菜单

#define SHDVID_GETMIMECSETMENU 27

CMenu menu;

menu.LoadMenu( IDR_IE_DEFAULT_POPUP ); // 自己山寨的IE菜单

// 获取菜单子项位置

int nSubMenuPos = -1;

switch ( dwID )

{

// 默认

case CONTEXT_MENU_DEFAULT:

nSubMenuPos = 0;

break;

// 图像

case CONTEXT_MENU_IMAGE:

nSubMenuPos = 1;

break;

// 锚

case CONTEXT_MENU_ANCHOR:

nSubMenuPos = 2;

break;

// DYNSRC 图像

case CONTEXT_MENU_IMGDYNSRC:

nSubMenuPos = 3;

break;

// ART 图像

case CONTEXT_MENU_IMGART:

nSubMenuPos = 4;

break;

default:

break;

}

if ( nSubMenuPos == -1 )

return S_FALSE;

// 获取子菜单位置

CMenuHandle menuHandle = menu.GetSubMenu( nSubMenuPos );

if ( menuHandle.IsNull() )

return S_FALSE;

// 弹出菜单

HRESULT hr;

HWND hwnd;

CComPtr<IOleCommandTarget> spCT;

CComPtr<IOleWindow> spWnd;

hr = pcmdtReserved->QueryInterface(IID_IOleCommandTarget, (void**)&spCT);

if ( FAILED(hr) )

return S_FALSE;

hr = pcmdtReserved->QueryInterface(IID_IOleWindow, (void**)&spWnd);

if ( FAILED(hr) )

return S_FALSE;

hr = spWnd->GetWindow(&hwnd);

if ( FAILED(hr) )

return S_FALSE;

// 添加编码

CComVariant var;

hr = spCT->Exec(&CGID_ShellDocView, SHDVID_GETMIMECSETMENU, 0, NULL, &var);

if ( SUCCEEDED(hr) )

{

MENUITEMINFO mii = {0};

mii.cbSize = sizeof(mii);

mii.fMask = MIIM_SUBMENU;

mii.hSubMenu = (HMENU) var.byref;

// 添加语言栏

menuHandle.SetMenuItemInfo(IDM_LANGUAGE, FALSE, &mii);

}

// 从注册表中加载扩展菜单(MenuExt)

CComVariant var1;

V_VT(&var1) = VT_INT_PTR;

V_BYREF(&var1) = (HMENU)menuHandle;

CComVariant var2;

V_VT(&var2) = VT_I4;

V_I4(&var2) = dwID;

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

if ( FAILED(hr) )

{

// 删除扩展菜单项

menuHandle.DeleteMenu(IDM_MENUEXT_PLACEHOLDER, MF_BYCOMMAND);

}

// 弹出菜单

int iSelection = menuHandle.TrackPopupMenu( TPM_LEFTALIGN | TPM_RIGHTBUTTON | TPM_RETURNCMD,

ppt->x, ppt->y, hwnd );

/************************************************************/

// iSelection==菜单ITEM ID，对指定的ID项进行特殊处理。咔咔，你懂的。

/************************************************************/

// 对菜单进行默认处理

::SendMessage(hwnd, WM_COMMAND, iSelection, NULL);

return S_OK;

}

附上山寨的IE右键菜单(用PE Explorer取到的ITEM)
