How to pass a range in OLEMethod?

Question

I have this code for inserting an image into a DOC:
COleVariant varFile(szFilename);
COleVariant varLink((BYTE)0);
COleVariant varSave((BYTE)1);
OLEMethod(DISPATCH_METHOD,NULL,pInlineShapes,L"AddPicture",3,
varSave.Detach(), // Save in document
varLink.Detach(), // Link to picture or embedd
varFile.Detach()); // Filename
But from this C# I see I can specify a range:
InlineShape AddPicture(
string FileName,
ref Object LinkToFile,
ref Object SaveWithDocument,
ref Object Range
How do I pass a Range in the C++ OLEMethod?

Hi Owen,
Thanks for posting in MSDN forum.
What is OLEMethod? Is it a function created by yourself? I search and find this article has a OLEMethod, maybe you are using the code introduced in it.
http://www.codeproject.com/Articles/34998/MS-Office-OLE-Automation-Using-C
If your OLEMethod is from about article, I think you have no need to pass a Range to the OLEMethod function.
Please check the implements of CMSWord::InserPicture and OLEMethod function in the article. Before you invoke this:
OLEMethod(DISPATCH_METHOD,NULL,pInlineShapes,L"AddPicture",3,
varSave.Detach(),varLink.Detach(),varFile.Detach());
You get the Selection property that will tell you where your picture will insert into by using these code.
IDispatch *pSelection;
VARIANT result;
VariantInit(&result);
OLEMethod(DISPATCH_PROPERTYGET, &result, pDocApp, L"Selection", 0);
pSelection=result.pdispVal;
So I think you don't need to pass a Range variable to the OLEMethod because you are not using a C# way to add a picture.
