I'm not sure if this Main Topic is the right one for my topic but i couldn't find more suitable main topic to ask my question :)
i have a web application for creating excel files. in my excel file,some cells' format are protected. for example, you can not enter string type data into a cell which is formatted to accept double type data.but some one has broken this protection.
yesterday a friend of mine downloaded my excel file and broke my protection.When i ask him, he said that he is copying and pasting the same data to any cell he wants.
So, here is my question:
How can i disable ctrl+x ctrl+c ctrl+v in my excel file?could any one give me an example for c#?
I appreciate any little help.
