Hi all, thank you guys for your help.

After checking with other folks that are doing more or less the same development we are trying to move on with generating an image before calling winword.exe.

Right before we call winword.exe process inside C#, we are generating the QR code and saving it locally as file. There are many requests per second, so the image cannot be the same, it will have a specific ID per image.

Now this may be more C# than word, but when we are calling winword.exe, we are sending an XML with the information that will fulfill bookmarks, and I'd like to have some sort of image object inside Word, and when applying the XML, that image assumes the path that is sent on the XML.

We are trying unsuccessfuly to make this work, is this possible?
