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;

}
