Hi Layzie292,
first you will have to save the control to an image, and then you can place the image in Word. To create the image, use:
WaveformGraph1.ToFile("<path here>", ImageType.Jpep);
You should then be able to place it into the word document using:
wordDoc.InlineShapes.AddPicture("<pic path here>", ref object LinkToFile, ref object SaveWithDocument, ref object Range);
Let me know if you have any further questions!
