Solution 1

I think the error message is quite clear about what you are doing wrong. You just need to use the correct form of MessageBox.Show().

It also helps if you use copy and paste to add error messages to your post, rather than typing your interpretation of it.

Why don't you change this line:

C#

DialogResult result = TopMostMessageBox.Show("Your Password will Expire in" +
                                             " " + Futdays + " " + "Day(s)" + "\n" + 
                                             "Do you want Change it now?",

to real like this:

C#

DialogResult result = TopMostMessageBox.Show(string.Format("Your Password will Expire in {0} Day(s).\nDo you want Change it now?", Futdays),

It's much more efficient...

John, it is not much more sufficient. The compiler is smart enough to convert all of those consecutive strings literals to just one string in IL. (Without any runtime concatenation cost)

That means the original code is only concatinating three strings. Of course the String.Format() is still probably a better way to go, but not much more efficient.

It's much more efficient to bebug the String.Format version than the OP's version.
