C++ Using AddPicture() InlineShapes method with Range parameter

Question

Please help, I have exhausted all other resources on the internet.

There is very limited documentation on using this method with C++. Most of the documentation is for VB. Please help me to 1) create a range object or range parameter type 2) use this range object with the AddPicture() method. Here is the AddPicture definition for C++:

LPDISPATCH InlineShapes::AddPicture(LPCTSTR FileName, VARIANT* LinkToFile, VARIANT* SaveWithDocument, VARIANT* Range)

Below is working code that inserts an image into a word document. It inserts at top of doc because the range parameter(4th parameter, currently 'covOptional') is not specified. There is other code that sets up m_disp to interact with document of interest.

_Document objDoc;
COleVariant covOptional;
//instantiate the document object
objDoc.AttachDispatch(m_disp);
//adding image to doc
InlineShapes objInlineShapes(objDoc.GetInlineShapes())
objInlineShapes.AddPicture("C:\\QR.png", covOptional, covOptional, covOptional);

Here is more info on what I am trying to do incase there are alternative ways. I have a word document that I need to add a png image to. I see a couple ways of doing this: 1) hardcode range objects that specify the position in the document of the png to be inserted into 2) add anchor strings (ex. %pngLocation%) to the document. Find a way to return a range that represents this string's location. Use that range with the AddPicture() method.

For example, this is a part of code of a C++/Win32 app (by using #import on MSWORD.OLB) where I insert an image at 200th character :
(with the simplest form of Range, from Range object)

		Word::_Application* pWord;  
		// Get Word Application in pWord...  
		Word::DocumentsPtr pDocs = pWord->Documents;  
		Word::_DocumentPtr pDoc = pDocs->Open2000(&variant_t("E:\\Test.doc"),&variant_t(false), &variant_t(false), &variant_t(false));  
		Word::WindowPtr pWindow = pWord->GetActiveWindow();  
        Word::Range* pRange = pWindow->Selection->GetRange();  
		pRange->Start = 200;  
		pRange->End = 200;  
  
		VARIANT vTargetRange;  
		vTargetRange.vt = VT_DISPATCH;  
		vTargetRange.pdispVal = pRange;  
		  
		Word::InlineShapes* pInlineshapes;  
		pInlineshapes = pDoc->GetInlineShapes();  
		  
		CComVariant covTrue((short)true);  
		CComVariant covFalse((short)false);  
		BSTR bstr = SysAllocString(L"E:\\hulk.png");  
		pInlineshapes->AddPicture(bstr, &covFalse, &covTrue, &vTargetRange);
