'Border' is not a valid template type argument for parameter 'T'

[oransen]

I'm trying to get the Border of a drawing (IDW) but compilation fails...

error C2923: 'ATL::CComPtr': 'Border' is not a valid template type argument for parameter 'T'

Here's the code, all my other uses of ComPtr<T> work perfectly:

    CComPtr<Sheet> pSheet = nullptr ;
 
    // Get some data about the sheet...
    double SheetHeight,SheetWidth,Border ;
    CComBSTR bstrSheetName ;
    pSheet->get_Name (&bstrSheetName) ;

    pSheet->get_Width(&SheetWidth) ;
    pSheet->get_Height(&SheetHeight) ;

    CComPtr<Border> pBorder; // <---- Border is not a type name !!!HERE!!!
    pSheet->get_Border(&pBorder);

What am I missing? get_Border exists as a function, but the type Border no it seems...

@oransen,

---

    CComPtr<Sheet> pSheet = nullptr ;
 
    // Get some data about the sheet...
    double SheetHeight,SheetWidth,Border ;
    CComBSTR bstrSheetName ;
    pSheet->get_Name (&bstrSheetName) ;

    pSheet->get_Width(&SheetWidth) ;
    pSheet->get_Height(&SheetHeight) ;

    CComPtr<Border> pBorder; // <---- Border is not a type name !!!HERE!!!
    pSheet->get_Border(&pBorder);

As per above code, pSheet is assigned to nullptr and not assigned any value to it. This is what missing in your code.

In my system, get_border is working fine. Try below C++ code to get border.

	HRESULT Result = NOERROR;	

	CLSID InvAppClsid;
	Result = CLSIDFromProgID(L"Inventor.Application", &InvAppClsid);
	if (FAILED(Result)) return Result;

	CComPtr<IUnknown> pInvAppUnk;
	 
	Result = ::GetActiveObject(InvAppClsid, NULL, &pInvAppUnk);
	if (FAILED(Result))
		_tprintf_s(_T("*** Could not get hold of an active Inventor application ***\n"));
	 
	if (FAILED(Result)) return Result;

	CComPtr<Application> pInvApp;
	Result = pInvAppUnk->QueryInterface(__uuidof(Application), (void **)&pInvApp);
	if (FAILED(Result)) return Result;

	CComPtr<Document> pDoc;
	Result = pInvApp->get_ActiveDocument(&pDoc);

	CComPtr<DrawingDocument> pDrawDoc;
	pDrawDoc = pDoc;

	CComPtr<Sheet> pSheet;
	Result = pDrawDoc->get_ActiveSheet(&pSheet);

	CComPtr<Border> pBorder;
	Result = pSheet->get_Border(&pBorder);

	return S_OK;

@chandra.shekar.g , thanks for testing. I rebuilt the whole solution and now Border is a recognised type.
