finally

Maby this is simple for you, but for me is not. I have this code:

Private int InsertData()
{ 
  int rezultat = 0;
       try
       {
           if (sqlconn.State != ConnectionState.Open)
           {
               sqlconn.Open();
           }
           rezultat = (int)cmd.ExecuteScalar();

       }
       catch (Exception ex)
       {
           lblMesaje.Text = "Eroare: " + ex.Message.ToString();

       }
       finally
       {
           if (sqlconn.State != ConnectionState.Closed)
           {
               sqlconn.Close();
           }
       }

       return rezultat;
}

Is just for inserting a new record in a table. Even if this throw an error "Specified cast is not valid." "rezultat=(int)cmd.ExecuteScalar();" - the code is executed and the row is inserted in the database, and the execution continues.

Why it continues? Maby i don't understand the try catch finally yet Smile | :)

Thank you!

I think error handling is a good idea. :) When debugging it can get in the way - especially with nice user friendly messages.
