Hi Folks! I'm getting stuck to a problem now for quite a long time. I want to use MathType (www.dessci.com) for my own application. Thats why i have to insert an ole object into a System.Windows.Controls.Canvas derived control. I searched the internet for quite a long time, not with real success. I found out that I probably have to use ole32.dll to get the object, but I did not find a tutorial or something that could have helped me. Has anyone done it before? Could anyone give me a hint? Thank you very much! Greetings, Chris
