    • The path of the file whose resources you are updating
    • The language of resource (like english french etc which are represented by a number like 1033 stands for english)
    • The name of the resource (Keep in mind the name of the resource can be both a string value or a number )
    • A new byte array which will contain binary data of any file you need to replace the resource with it can be images etc
    • Remember in resource name if resource name is "12" you cant write 12 . It will be a numerical value but the actual value is 12 so you will need to write that only.

      For all these things(resource name,resource language etc) you can use a wonderful freeware called resource hacker .
