I want to build a online document reader which is a part of my project. I want to work with MS Word document where user have some access to the documents, according to the access he/she have (will be able to edit the document and save). I want to make it as other online documents there like Safari Online Book Reader or Google Book Reader where there is no functionality of right clicking and saving the document, I want to do the same for the users who have only readonly functionality and to give editting options to those who have editting access.
So Let me know how should I go for it. As MS Word API is easy to use I want to use it for this purpose. I want to code that in .Net (c#)
