I am trying to use WordprocessingDocument of OpenXML in C# to create MS WORD document.
I succeeded to add the normal paragraph, but, I have problem on adding math equation.

I’m trying to create a word document that shows student’s pictures. the picture are shown in a table. When all the picture for a student have been printed, it goes to the next one on a new page. I would like to have a specific header for each student. So if student1 has got 2 pages of pictures, header should say “Header for Student 1” on both pages, then it creates a new page and header should change to “Header for Student 2”. Currently, the header remains the same on each page for all students. It’s always “Header for Student 1”.
