C++和CSharp增加AutoCAD的菜单menu

一 c++ COM接口

void
addMenuThroughCom()
{

    AutoCAD::IAcadApplication *pAcad;
    AutoCAD::IAcadMenuBar *pMenuBar;
    AutoCAD::IAcadMenuGroups *pMenuGroups;
    AutoCAD::IAcadMenuGroup *pMenuGroup;
    AutoCAD::IAcadPopupMenus *pPopUpMenus;
    AutoCAD::IAcadPopupMenu *pPopUpMenu;
    AutoCAD::IAcadPopupMenuItem *pPopUpMenuItem;

    HRESULT hr = NOERROR;
    LPUNKNOWN pUnk = NULL;
    LPDISPATCH pAcadDisp = acedGetIDispatch(TRUE); 
    if(pAcadDisp==NULL)
        return;

    hr = pAcadDisp->QueryInterface(AutoCAD::IID_IAcadApplication,(void**)&pAcad);
    pAcadDisp->Release();
    if (FAILED(hr))
        return;

    pAcad->put_Visible(true);
    pAcad->get_MenuBar(&pMenuBar);
    pAcad->get_MenuGroups(&pMenuGroups);
    pAcad->Release();
    long numberOfMenus;

    VARIANT index;
    VariantInit(&index);

    WCHAR wstrMenuName[256];
    #ifdef UNICODE

    #else  // !UNICODE
        MultiByteToWideChar(CP_ACP, 0, "AsdkComAccess", -1, wstrMenuName, 256); 
    #endif // !UNICODE

    // Enables the menu to be loaded/unloaded with the same command.
    if (!bIsMenuLoaded) {
        pPopUpMenus->Add(wstrMenuName, &pPopUpMenu);

        if (pPopUpMenu != NULL) {

            WCHAR wstrMenuItemName[256];
            WCHAR wstrMenuItemMacro[256];
            #ifdef UNICODE
                _tcscpy(wstrMenuItemName, L"&Add A ComCircle");

            #endif // !UNICODE

            VariantInit(&index);
            V_VT(&index) = VT_I4;
            V_I4(&index) = 0;
            pPopUpMenu->AddMenuItem(index, wstrMenuItemName, wstrMenuItemMacro, &pPopUpMenuItem);

            VariantInit(&index);
            V_VT(&index) = VT_I4;
            V_I4(&index) = 1;
            pPopUpMenu->AddSeparator(index, &pPopUpMenuItem);

            #ifdef UNICODE

二 C++基于MFC的

void
addMenuThroughMfcCom()
{
    TRY
    {
        CAcadApplication IAcad(acedGetAcadWinApp()->GetIDispatch(TRUE));

        CAcadMenuBar IMenuBar(IAcad.get_MenuBar());

        long numberOfMenus;
        numberOfMenus = IMenuBar.get_Count();

        CAcadMenuGroups IMenuGroups(IAcad.get_MenuGroups());

        VARIANT index;
        VariantInit(&index);
        V_VT(&index) = VT_I4;
        V_I4(&index) = 0;

        CAcadMenuGroup IMenuGroup(IMenuGroups.Item(index));

        CAcadPopupMenus IPopUpMenus(IMenuGroup.get_Menus());

        CString cstrMenuName = _T("AsdkComAccess");

        VariantInit(&index);
        V_VT(&index) = VT_BSTR;
        V_BSTR(&index) = cstrMenuName.AllocSysString();

        IDispatch* pDisp=NULL;

        //see if the menu is already there
        TRY{pDisp = IPopUpMenus.Item(index); pDisp->AddRef();} CATCH(COleDispatchException,e){}END_CATCH;

        if (pDisp==NULL) {
            //create it
            CAcadPopupMenu IPopUpMenu(IPopUpMenus.Add(cstrMenuName));

            VariantInit(&index);
            V_VT(&index) = VT_I4;
            V_I4(&index) = 0;
            IPopUpMenu.AddMenuItem(index, _T("&Add A ComCircle"), _T("_AsdkMfcComCircle "));

            VariantInit(&index);
            V_VT(&index) = VT_I4;
            V_I4(&index) = 1;
            IPopUpMenu.AddSeparator(index);

            VariantInit(&index);
            V_VT(&index) = VT_I4;
            V_I4(&index) = 2;
            IPopUpMenu.AddMenuItem(index, _T("Auto&LISP Example"), _T("(prin1 \"Hello\") "));

            pDisp = IPopUpMenu.m_lpDispatch;
            pDisp->AddRef();
        }

        CAcadPopupMenu IPopUpMenu(pDisp);
        if (!IPopUpMenu.get_OnMenuBar())
        {
            VariantInit(&index);
            V_VT(&index) = VT_I4;
            V_I4(&index) = numberOfMenus - 2;;
            IPopUpMenu.InsertInMenuBar(index);
        }
        else
        {
            VariantInit(&index);
            V_VT(&index) = VT_BSTR;
            V_BSTR(&index) = cstrMenuName.AllocSysString();
            IPopUpMenus.RemoveMenuFromMenuBar(index);
            VariantClear(&index);
        }
        pDisp->Release();
    }
    CATCH(COleDispatchException,e)
    {
        e->ReportError();
        e->Delete();
    }
    END_CATCH;
}

using Autodesk.AutoCAD.Runtime;

namespace CSharpCOM
{
    public class Class1
    {
        public Class1() { }

        [CommandMethod("AM")]
        public static void AddMenuCom()
        {
            AcadApplication app = (AcadApplication)Marshal.GetActiveObject("AutoCAD.Application.17");
            AcadMenuBar menuBar = app.MenuBar;
            AcadMenuGroup menuGroup = app.MenuGroups.Item(0);
            AcadPopupMenus menus = menuGroup.Menus;
            AcadPopupMenu mymenu = menus.Add("MyMenu");

            mymenu.AddMenuItem(0, "Hello", "hello");
            mymenu.AddSeparator(1);
            mymenu.AddMenuItem(2, "Hello2", "hello");
            AcadPopupMenu ext = mymenu.AddSubMenu(3, "Ext");
            ext.AddMenuItem(0, "Hello", "hello");
            ext.AddSeparator(1);
            ext.AddMenuItem(2, "Hello2", "hello");
            mymenu.InsertInMenuBar(menuBar.Count - 2);
        }

        [CommandMethod("hello")]
        public static void Hello()
        {
            AcadApplication app = (AcadApplication)Marshal.GetActiveObject("AutoCAD.Application.17");
            app.ActiveDocument.Utility.Prompt("Hello\n");
        }


    }
