Adding file in Excel with ActiveX and OLEObject

Hello,

I have a question about Excel automation and OLEObject.

I have a code that generate a Excel report using ActiveX. My purpose is to insert a file (in my case .html) in a Excel worksheet so that the user can access it by cliking on the icon :

Here the code I tested (Matlab 2016b) :

e = actxserver('Excel.Application');
WB = e.Workbooks.Open(MyExcelFile);
eSheets = e.activeWorkbook.Sheets;
eSheetDatas = eSheets.get('Item', 1);
eSheetDatas.Activate 
eSheetDatas.OLEObjects.Add([],MyHTMLFile,0,1,[],[],[],100,500,50,50); % For the options I want to fix a position, and show an icon
Close(WB)
Quit(e)
delete(e)

When I run this, Matlab get stuck like in infinite loop.

I think the syntax of the OLEObject.Add is not good for matlab.

Any help please ?

I did some more tests. In fact my code got stuck on the line :

Close(WB)

But only if I use add an OLE object before. I already used Close(WB) on another code with writing datas and changing forms and it worked well.

So I thouth about an issue while saving the xls file with the OLE object and tried this :

WB.Close(1, MyExcelFile)

But same behavior. Matlab get stuck on this line without closing the file.

If someone has an idea.
