Default Stored procedure IConvertible

I use the following stored procedure to get the UserID. If there is a matching Password and user name then UserId > 0 if not then UserID = 0

CREATE PROCEDURE dbo.spValidateUser(

@MyUserName varchar(50),
@MyPasswordID varchar(50)


SELECT UserID FROM UserAccounts
WHERE UserName = @MyUserName
AND PasswordID = @MyPasswordID

And the code is:

SqlCommand mySelect = new SqlCommand("spValidateUser", sqlConnection1);
sqlDataAdapter1.SelectCommand = mySelect;
mySelect.CommandType = CommandType.StoredProcedure;
SqlParameter myParameter = null;

SqlParameter myParameter1 = myParameter1;
//Set parameters for stored procedure

myParameter = mySelect.Parameters.Add("@MyUserName", SqlDbType.VarChar, 50);
myParameter.Value = txtUserName;
myParameter = mySelect.Parameters.Add("@MyPasswordID", SqlDbType.VarChar, 50);
myParameter.Value = txtPassword;


//Get the value
int returnValue = (int) mySelect.ExecuteScalar();
string strA;
//Convert from int to string
strA = Convert.ToString(returnValue);
lblMessage.Text = Convert.ToString(returnValue);

I get the following message:

Exception Details: System.InvalidCastException: Object must implement IConvertible.

Source Error:

Line 186:
Line 187: //Get the value
Line 188: int returnValue = (int) mySelect.ExecuteScalar();
Line 189: string strA;
Line 190: //Convert from int to string

Could you please tell me what im doing wrong???

Hey Nick,

You got to post that on a .Net/C# forum here, to get better response on this. This is an SQL server with Classic ASP forum.
