Sure: you're going wrong trying to convert an int to an SqlDataReader . You're also trying to convert an SqlDataReader to an int, later on.
Your "GetMainCatCount" method returns an int, but you're assigning its return value to a variable of type SqlDataReader.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
