Point well taken! I'm developing a C# .Net Windows Forms application, and am trying to "host" mshtml.
Observing ItWriting's code, I saw it implements OLE2 interfaces to host the mshtml control. Mshtml was written to be used through OLE, so that's it. Indeed: "if you're trying to 'host' a control you need to emulate the environment for which the control was written". However, I have a "philosophical" (or design) question and this is why I posted my question to the _advanced_ list! I differentiate between COM and OLE not chronologically but by taking the network layers metaphor: (*) COM is low level, IUnknown, class factories, VTable, IDispatch, etc. (*) OLE is a _ COLLECTION_ of several specific COM interfaces, decreed by MS to be the glue between applications where a document of one application is hosted within another: merging of menus and activation of a document hosted within a container. So,_today_, what is the way to integrate between applications? If I wrote Word.Net today, and wanted it to be able to serve as the message editing component of Outlook.Net, and wanted to be able to embed an Excel.Net spreadsheet within my mail message, would I still implement those specific COM interfaces? Would .Net do it for me transparently? =================================== This list is hosted by DevelopMentor� http://www.develop.com Some .NET courses you may be interested in: NEW!
