c++ - 如何将多个菜单项添加到 windows shell 扩展？

Question

我正在尝试将多个菜单项添加到 Windows shell 的上下文菜单中。到目前为止我所做的是以下代码，这将我的项目添加为子菜单，而我希望它们位于主上下文菜单中。这是一张照片:

有什么想法吗？谢谢!

STDMETHODIMP CFileFavShellExt::QueryContextMenu (HMENU hmenu, UINT uMenuIndex, UINT uidFirstCmd, UINT uidLastCmd, UINT uFlags )
{
    // This is not our business.
    if (CMF_DEFAULTONLY & uFlags)
    {
        return MAKE_HRESULT(SEVERITY_SUCCESS, 0, 0);
    }

    UINT uID = uidFirstCmd;

    if (!InsertMenu(hmenu, uMenuIndex, MF_SEPARATOR | MF_BYPOSITION, 0, NULL))
    {
        return HRESULT_FROM_WIN32(GetLastError());
    }

    // Creating my menu.
    HMENU hSubmenu = CreateMenu();

    InsertMenu (hSubmenu, 0, MF_BYPOSITION, uID++, _T("Add to bookmarks 1"));
    InsertMenu (hSubmenu, 1, MF_BYPOSITION, uID++, _T("Add to bookmarks 2"));

    MENUITEMINFO mii = { sizeof(mii) };
    mii.fMask = MIIM_SUBMENU | MIIM_ID | MIIM_STRING;
    mii.hSubMenu = hSubmenu;
    mii.fType = MFT_STRING;
    mii.dwTypeData = _T("Bla");
    mii.wID = uID++;

    if (!InsertMenuItem(hmenu, uMenuIndex, TRUE, &mii))
    {
        return HRESULT_FROM_WIN32(GetLastError());
    }

    if (!InsertMenu(hmenu, uMenuIndex, MF_SEPARATOR | MF_BYPOSITION, 0, NULL))
    {
        return HRESULT_FROM_WIN32(GetLastError());
    }

    return MAKE_HRESULT(SEVERITY_SUCCESS, FACILITY_NULL, uID - uidFirstCmd);
}

编辑:我尝试了另一种不使用子菜单的方法，但仍然没有成功，我得到的只是“菜单 1”，而“菜单 2”不见了......

STDMETHODIMP CFileFavShellExt::QueryContextMenu (HMENU hmenu, UINT uMenuIndex, UINT uidFirstCmd, UINT uidLastCmd, UINT uFlags )
{
    // This is not our business.
    if (CMF_DEFAULTONLY & uFlags)
    {
        return MAKE_HRESULT(SEVERITY_SUCCESS, 0, 0);
    }

    UINT uID = uidFirstCmd;
    UINT pos = uMenuIndex;

    MENUITEMINFO mii = { sizeof(mii) };
    mii.fMask = MIIM_STRING | MIIM_FTYPE | MIIM_ID | MIIM_STATE;
    mii.fType = MFT_STRING;
    mii.dwTypeData = _T("Menu 1");
    mii.fState = MFS_ENABLED;
    mii.wID = uID++;

    if (!InsertMenuItem(hmenu, pos++, TRUE, &mii))
    {
        return HRESULT_FROM_WIN32(GetLastError());
    }

    MENUITEMINFO mii2 = { sizeof(mii) };
    mii2.fMask = MIIM_STRING | MIIM_FTYPE | MIIM_ID | MIIM_STATE;
    mii2.fType = MFT_STRING;
    mii2.dwTypeData = _T("Menu 2");
    mii2.fState = MFS_ENABLED;
    mii2.wID = uID++;

    if (!InsertMenuItem(hmenu, pos++, TRUE, &mii2))
    {
        return HRESULT_FROM_WIN32(GetLastError());
    }

    return MAKE_HRESULT(SEVERITY_SUCCESS, FACILITY_NULL, uID - uidFirstCmd);
}

子菜单在那里是因为您正在添加它。

MENUITEMINFO mii = { sizeof(mii) };
mii.fMask = MIIM_SUBMENU | MIIM_ID | MIIM_STRING;
mii.hSubMenu = hSubmenu;
mii.fType = MFT_STRING;
mii.dwTypeData = _T("Bla");
mii.wID = uID++;

if (!InsertMenuItem(hmenu, uMenuIndex, TRUE, &mii))
{
    return HRESULT_FROM_WIN32(GetLastError());
}

这会添加“Bla”子菜单，您已将其他项目添加到该子菜单中。要删除子菜单，只需删除此代码，然后将其他项目直接添加到主菜单即可。
