• DataBinder (Pros and Cons)

  DataBinder.Eval method saves you from writing complex expressions ;) BUT, using this method does impose a performance penalty on your code, because all the work it does is late-bound. Ok, if we want the fastest possible code, you can replace calls to DataBinder.Eval with explicit casts. For example: <%# DataBinder.Eval(Container.DataItem, “myField”,“{0:c}”) %> An equivalent expression using casts would be this: <%# String.Format(“{0:c}”,(CType(Container.DataItem,DataRowView)(“myField”))) %> Good ;) Posted Oct 19 2003, 01:54 PM by rbfigueira with 2 comment(s) Filed under: Dotnet

• VB.NET vs C# (best choice)

  I was reading this article and .... : http://www.aspnetpro.com/opinion/2003/09/asp200309en_o/asp200309en_o.asp "Whether it's just or not, C# developers make more money, get work more easily, and enjoy more prestige than VB developers." "ASPSOFT president and asp.netPRO columnist Jonathan Goodyear describes how, at his client's insistence, he converted a VB .NET code base to C#, then says, "The overwhelming majority of my clients ... are resolute in their insistence on our use of C# while building their software." Do you agree with this ?!! My simple conclusion: It's crucial to learn C# ;P Note: I prefer to do my stuff on vb.net but i know both languages (vb.net and c#) ;) Posted Oct 15 2003, 10:21 AM by rbfigueira with 19 comment(s) Filed under: General, Dotnet

• MSDN Event (Lisbon: 08 October)

  I was on the MSDN event (Lisbon: 08 October) – Portugal! Yes, that little country ;) They talk about programming with ADO.NET (good practices) ;) On “Errors on Stored Procedures” subject: “ Informative messages (severity <=10) can be capture by ADO.NET” by Vasco Nunes Example: “Conn” is your connection We can build one event handler on infoMessage (connection), like this: AddHandler conn.infoMessage, New SqlClient.SqlinfoMessageEventHandler(Addressof MessageEventHandler) Sub MessageEventHandler(ByVal sender As Object, ByVal e As SqlClient.SqlinfoMessageEventArgs)     ‘do whatever End Sub Great ;) Posted Oct 13 2003, 10:59 AM by rbfigueira with no comments Filed under: General, Dotnet
