Hi shailesh, I had seen your code. It works perfect when I load .docx file into richtextbox. But when I save file Its not working. So, I am sharing the link for the solution. https://www.c-sharpcorner.com/article/color-syntax-editor-part-ii-exporting-a-richtextbox-to-a-m/

@Piyush  thanks for your link sharing.   but would like to inform you that this link also does not save file as ".docx" or properly open ".doc" file.   it exports fileas "rtf" which is not wanted.   i need pure ".docx" file save and open ".doc" file
