Can't change access modifiers when inheriting from Generic Types.

Well I might be silly, but I had not run-up to this one yet. Until just now:

You cannot change the accessibility level of a class member by means of hiding when inheriting from a generic type.

Consider this example. A simple console application using two classes: MyList inherits from List<int> and My2ndList inherits from MyList. Generic type List<T> has a public method named Add that is not declared as virtual.

My intention was to completely hide the base implementation of the Add method in my derived class. In other words, let's assume that I want MyList class to not expose an Add method. What one would normally do in this case, would be to hide the method by using the new modifier and changing its access modifier from public to private like I tried to do in line 32 of the code snippet that follows.

Well. Guess what. This does not work if you are inheriting from a Generic Type. Try the code bellow then try to play around with the access modifiers in lines 32 and 47. Although I would normally assume that the code bellow would not even compile, it does!

   1: using System;

   2: using System.Collections.Generic;

   3: using System.Text;

   4:  

   5: namespace TestGenerics

   6: {

   7:     class Program

   8:     {

   9:         static void Main(string[] args)

  10:         {

  11:             MyList myList = new MyList();

  12:             myList.Add(1);

  13:             myList.Add(2);

  14:             myList.Add(3);

  15:  

  16:             myList.Print();

  17:  

  18:             Console.WriteLine("Now the 2nd List");

  19:             

  20:             My2ndList my2ndList = new My2ndList();

  21:             my2ndList.Add(1);

  22:             my2ndList.Add(2);

  23:             my2ndList.Add(3);

  24:  

  25:             my2ndList.Print();

  26:         }

  27:  

  28:     }

  29:  

  30:     public class MyList : List<int>

  31:     {

  32:         new private void Add(int item)

  33:         {

  34:             item *= 10;

  35:             base.Add(item);

  36:         }

  37:  

  38:         public void Print()

  39:         {

  40:             foreach (int item in this)

  41:                 Console.WriteLine(item.ToString());

  42:         }

  43:     }

  44:  

  45:     public class My2ndList : MyList

  46:     {

  47:         new private void Add(int item)

  48:         {

  49:             item *= 100;

  50:             base.Add(item);

  51:         }

  52:     }

  53: }

So why am I posting about this?

Well... I didn't come across any comments on the subject on the Internet for the little I looked around and I thought it was an interesting thing to talk about.

If you know of any links discussing the subject and explaining the internals of the compiler or generics implementation in C#, then by all means please do leave a comment to this post.

If you'd like to copy/paste the code above then go get it here.

Multiple calls to RegisterOnSubmitStatement and Client-Side Validation

Ok! Here is a new thing I discovered yet again the hard way...

In short: Do not call Page.ClientScript.RegisterOnSubmitStatement after the Page Load event.

(What?!)

Well yes! It's not under all circumstances that you can notice the difference but it's there and it's major!

I do not really wan to describe this, so I 'll take you though it with an example:

Let's say you have an aspx page. The page has two controls in it. For simplicity lets make those controls UserControls. The controls are pretty simple: just a TextBox and a RequiredFieldValidator in each of them.

So there you have it:

Control A (let's call it OnSubmitControlA):

<%@ Control Language="C#" AutoEventWireup="true" CodeFile="OnSubmitControlA.ascx.cs" Inherits="OnSubmitControlA" %>
<asp:TextBox ID="TextBox1" runat="server" />
<asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server" ControlToValidate="TextBox1" ErrorMessage="RequiredFieldValidator" />

and the code file:

public partial class OnSubmitControlA : System.Web.UI.UserControl
{
   protected override void OnPreRender(EventArgs e)
   {
      Page.ClientScript.RegisterOnSubmitStatement(this.GetType(), "DoingSomething", "alert('This alert is registered by OnSubmitControlA');");
      base.OnPreRender(e);
   }
}

Control B (let's call it OnSubmitControlB):

<%@ Control Language="C#" AutoEventWireup="true" CodeFile="OnSubmitControlB.ascx.cs" Inherits="OnSubmitControlB" %>
<asp:TextBox ID="TextBox1" runat="server" />
<asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server" ControlToValidate="TextBox1" ErrorMessage="RequiredFieldValidator" />

and the code file:

public partial class OnSubmitControlB : System.Web.UI.UserControl
{
   protected override void OnPreRender(EventArgs e)
   {
      Page.ClientScript.RegisterOnSubmitStatement(this.GetType(), "DoingSomethingElse", "alert('This alert is registered by OnSubmitControlB');");
      base.OnPreRender(e);
   }
}

And finally the page itself:

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="OnSubmitTest.aspx.cs" Inherits="OnSubmitTest" %>
<%@ Register src="OnSubmitControlA.ascx" TagName="OnSubmitControlA" TagPrefix="uc1" %>
<%@ Register src="OnSubmitControlB.ascx" TagName="OnSubmitControlB" TagPrefix="uc2" %>
<html xmlns="http://www.w3.org/1999/xhtml" >
   <head runat="server">
      <title>Test Page</title>
   </head>
   <body>
      <form id="form1" runat="server">
         <uc1:OnSubmitControlA ID="OnSubmitControlA1" runat="server" />
         <uc2:OnSubmitControlB ID="OnSubmitControlB1" runat="server" />
         <asp:Button ID="Button1" runat="server" Text="Button" />
      </form>
   </body>
</html>

(the codefile has nothing special in it...)

So! What we have here!?

• A Page,
• two controls that wan to access client-side code just before the page submits (for no particular reason)
• and at least a Validator Control that will fail validation at some point. (If we did not have a validator then I would not have a case here!)

Now go render the page an see the result. If you leave either TextBox empty and click on the submit button, you will notice that only the alert from the first control pop's up. The other registered script is never called....

Now go back and make a slight change. Move in both contols' codefile the call to Page.ClientScript.RegisterOnSubmitStatement from OnPreRender to OnLoad, like this:

public partial class OnSubmitControlA : System.Web.UI.UserControl
{ 
   protected override void OnLoad(EventArgs e)
   {
      base.OnLoad(e);
      Page.ClientScript.RegisterOnSubmitStatement(this.GetType(), "DoingSomething", "alert('This alert is registered by OnSubmitControlA');");
   }
   protected override void OnPreRender(EventArgs e)
   {
      // Let's comment this out
      // Page.ClientScript.RegisterOnSubmitStatement(this.GetType(), "DoingSomething", "alert('This alert is registered by OnSubmitControlA');");
      base.OnPreRender(e);
   }
}

do the same on the other control:

public partial class OnSubmitControlB : System.Web.UI.UserControl
{
   protected override void OnLoad(EventArgs e)
   {
      base.OnLoad(e);
      Page.ClientScript.RegisterOnSubmitStatement(this.GetType(), "DoingSomethingElse", "alert('This alert is registered by OnSubmitControlB');");
   }
   protected override void OnPreRender(EventArgs e)
   {
      // Let's comment this out also
      // Page.ClientScript.RegisterOnSubmitStatement(this.GetType(), "DoingSomethingElse", "alert('This alert is registered by OnSubmitControlB');");
      base.OnPreRender(e);
   }
}

Done! Go back and render the page! Leave either TextBox empty and click submit... See??? Now both alerts pop up!!!

Why is that???

Well look at the source of the rendered page before and after the change to see what' going on:

Here is the script rendered when the call to RegisterOnSubmitStatement is placed in the OnPreRender event:

<script type="text/javascript">
<!--
   function WebForm_OnSubmit() {
      alert('This is registered by OnSubmitControlA');
      if (typeof(ValidatorOnSubmit) == "function" && ValidatorOnSubmit() == false) 
         return false;
      alert('This is registered by OnSubmitControlB');
      return true;
   }
// -->
</script>

And here is the script rendered when the call to RegisterOnSubmitStatement is placed in the OnLoad event:

<script type="text/javascript">
<!--
   function WebForm_OnSubmit() {
      alert('This is registered by OnSubmitControlA');
      alert('This is registered by OnSubmitControlB');
      if (typeof(ValidatorOnSubmit) == "function" && ValidatorOnSubmit() == false) 
         return false;
      return true;
   }
// -->
</script>

Got it?

If RegisterOnSubmitStatement is called after OnLoad, then the first time it's called the framework appends the statement that calls ValidatorOnSubmit() and returns false if it fails; (effectively blocking the rest of the script from executing). Subsequent calls of RegisterOnSubmitStatement (after OnLoad) are appended to the script generated by the first call (and get blocked by the effect I just described).

Instead, if all your calls to RegisterOnSubmitStatement come before the end of the OnLoad phase, then all registered scripts are appended to previously generated scripts before the eventual injection of the call to ValidatorOnSubmit().

Hoping for comments on this...

xsl:include, xsl:import & msxml:script blocked on WSS 3 XML WebParts

I discovered today (the hard way), that we can no longer use xsl:include and xsl:import elements in XSL Transformations for Windows SharePoint Services 3.0 XML WebParts.

Along with those msxml:script is also blocked.

I am going to investigate this further and see if there is an administrative way to bypass this security restriction. XSLT code reuse is a useful thing and I want to keep it as an option in some environments.

Anyhow...

I am including two relevant links I found on the web:

• SharePoint DVWP: xslt limitations... in Serge van den Oever's Blog
• SharePoint Data View Web Part Extension Functions in the ddwrt Namespace in MSDN

I would appreciate comments from people who know more on the subject.

CS:Editor ViewState

Quick Tip:

CommunityServer 2.1 uses TinyMCE as a rich text editor. They use what appears to be a wrapper to TinyMCE: CommunityServer.Controls.Editor. As I am developing an application on top of CS 2.1 I am using the same rich text editor and encountered the following problem:

I was setting declaratively the Height Property of the Editor control, but it could not retain it's value after postbacks.

Look at the ASPX part:

<%@ Register Assembly="CommunityServer.Controls" Namespace="CommunityServer.Controls" TagPrefix="CS" %>
<CS:Editor ID="edtNotes" runat="server" Height="160px" />

So far so good but, after a postback the Editor control returned to its default height (messing-up my layout).

To make a long story short, it figured that something is wrong either with timing or with implementation. I mean that either the wrapper, or the wrapped control do not assign the value of Height before ViewState is saved, or they assign it to either a Property that is not saved in view state, or during an Event that fires before LoadViewState.

So what I did to work-around the issue was just disable ViewState in the Editor control.

<CS:Editor ID="edtNotes" runat="server" Height="160px" EnableViewState="false" />

The problem has gone away and that means that LoadViewState was overwriting my value.

I did not devote any time in looking further into this matter so I'm just posting this work-around, but if I do, I 'll let you know the details.

Hiding a Report Parameter in SQL Server 2000 Reporting Services

Situation:

You use SQL 2000 Reporting Services, to create a report (probably same applies for SQL 2005, but I have not tried it yet).

You report expects various parameters but the user does not need to specify all of them through the user interface. For example the value of a parameter (say ParamB) can be calculated based on the value of another parameter (say ParamA) that the user selects.

So, you want to hide ParamB from the user.

Solution:

In the Report Parameters Collection Editor select the parameter that you want to hide and clear its “Prompt” field. Then add a Default Value to it (either by using an expression or by using a query).

Quick Tip:

 Notice that when you use a query to get the default value of the hidden parameter ParamB you can always pass to it the Value that the user selected for ParamA (or another parameter).

My Funny Surprises With .NET 2.0

As I was developing applications for .Net Framework 1.0 and 1.1, I was building a couple of code libraries with features I found smart and useful for my apps.

Being an active member of dotNetZone.gr, (a Greek .net developer community often nicknamed DNZ), I recently decided to share some of that code with others in DNZ.

The idea was to do that while porting the code to .Net Framework 2.0 through Visual Studio 2005.

Now, what’s so funny about that?

First thing I wanted to share was my Wizard classes. I implemented them in the context of a web project and used to find them brilliant.

Using SourceSafe Ι started today pinning and branching code to a new VS 2005 solution that would contain the part of my libraries related to Wizards.

“Come on! Where is the funny part?” you would still ask!

Well I compiled it and got the following compile time errors:

• Error1: 'Wizard' is an ambiguous reference between 'System.Web.UI.WebControls.Wizard' and 'Softbone.Shared.Wizards.Wizard' 
• Error 2: 'WizardStep' is an ambiguous reference between 'System.Web.UI.WebControls.WizardStep' and 'Softbone.Shared.Wizards.WizardStep' 
• Error 3 'WizardStepCollection' is an ambiguous reference between 'System.Web.UI.WebControls.WizardStepCollection' and 'Softbone.Shared.Wizards.WizardStepCollection' 

(note: Softbone is brand name I am using, and Softbone.Shared is the namespace of the shared code library I am creating porting my code from .net framework 1.1 to 2.0).

Ooops!

Not only Microsoft implemented the same functionality as I did, but the just happened to have chosen the same class names as I did!

Well that, I thought was funny enough to mention…

So, it might be the case that my library is obsolete with the new version of the .Net Framework, but still, here is what is more interesting about it now than ever: I have to check my implementation against Microsoft’s one to see where mine falls short or even if I did some things that are better or smarter than Microsoft’s.

So I will be posting my code soon to my main blog and my .net blog in DNZ and keep you posted here, to see if I have more interesting or funny encounters during my Wizard Library porting to .Net Framework 2.0.

I ‘ll let you know….

Netscape 8 blues starting...

Remember my recent blog entry about Netscape 8 excitement???

Remember I told you that the good news was that you can switch to IE engine with a click from within Netscape 8?

Well… here is the first bad news:

• Go find a site with a textarea control to fill in.
• Then switch Netscape to use the IE engine.
• Try to enter text in the textarea field. While doing that, try switching the active language (from Greek to English in my case). You know; by pressing Alt-Shift.
• Well, there goes the focus out of the control! Unless you pick up the mouse and move the focus back in, you will not be able to continue typing from where you left off.

The “bug” does not appear in textboxes (<input type=text>). Just textareas (<textarea></textarea>)….

Try to participate on a forum (i.e: a CS based forum), where you need toy change language frequently while you are typing… Hopeless…

Now I am wondering… Who’s “bug” is this Netscape’s or IE’s engine's???

We ‘ll see…

There are also a number of other issues I ran into from time to time (most related to IE engine's usage by Netscape. For instance try to hit the back button to return to a page with Greek Encoding. Page encoding does not always get applied resulting in an unreadable page you need to refresh. Probably this does not have to do with ISO-8859-7 (Greek) or Windows-1253 (Greek also) encodings only.

So far, although cool, the ability of Netscape 8 to try to function like IE (I suppose by using the browser control) is not that useful all the time...

JDiskReport by JGoodies...

In my time -believe it or not– I ‘ve seen far more Java Apps crash than Windows Apps (when running on Windows of course).. Nevertheless here is a little Java Application that not only never crashed on me but is also very useful: JDiskReport by JGoodies.com It will scan your hard drive and tell you the size of every folder in very graphical colorful an useful way. The guys who make it work mainly on Java UI design projects (with Swing), and probably built this app as an attraction to their cause. It’s the best in its class (to my opinion). Go get it!

Netscape 8

Since IE 4, my use of Netscape started to decline. After IE 5 I hardly ever used Netscape Navigator. It was not even installed on my computer. I just had it installed in a test machine to verify DHTML compliance with it whenever needed.

Until today!

I downloaded and installed Netscape 8 and discovered that apart from a nice browsing experience, Netscape now offers the ability to switch to the IE engine whenever wanted or needed.

Well that’s it! I now have Firefox and IE all in one: Netscape 8.

I am still excited with it and use it all the time. If things change I ‘ll let you know!

Till then, I suggest you try it yourself…

GreekEuroVerbalizer

Reading a recent post in dotNetZone.gr I decided to implement as a proof-of-concept an algorithm using regular expressions to convert a decimal numeral representing an amount of money, to a verbal from in Greek text.

So to make it more obvious the problem was to convert 1,234,567.89 Euros to the string "One Million, Two Hundred Thirty Four, Five Hundred Sixtyseven Euros and Eightynine Cents" (only that the text should be in Greek and not English as I typed here to make the concept clear for everyone).

The algorithm I came up with is not the best that I could do but is enough as a proof of concept. Do not be alarmed if it seems too long at first glance. It's just the code comments that make it so long.

So to find the algorithm:

• Either read it online in my relevant blog article in dotNetZone.gr here. Apart from code comments, all other text in the refered article is in Greek but since you are reading this you do not realy need to be able to understand anything else
• or download GreekEuroVerbalizer.zip (220,72 KB) which contains a VS.NET 2003 solution with a demo windows application that tests the algorithm.
• You can also view online a rough documentation created with nDoc from my source comments here.

με ‘γειά μου!

Προβληματίζομαι όμως…

Θέλω να βάλω Windows 2003 Server αλλά δεν μπορώ να το πάρω εύκολα απόφαση…

Για development με βολεύει πολύ αλλά έχω δύο drawbacks: δεν θα παίζουν τα “καλούδια” της Sony (που δεν ξέρω ακόμα να μου είναι απαραίτητα) και επίσης άμα με πιάσει σε κανένα ταξίδι να παίξω κανένα παιχνιδάκι (ένα Rome Total War ας πούμε) ή όποτε θελήσω να το χρησιμοποιήσω εν είδη media center στο σπίτι, δεν θα είναι το κατάλληλότερο για τη δουλειά…

Άσε που θα γκρινιάζει και η Sony αν μου προκύψει θέμα εγκύησης (ω μη γέννητω)..

Οπότε προς το παρόν το σκέφτομαι… Μάλλον όμως θα το κρατήσω μερικές μέρες με το XP κι αφού το τσεκάρω ότι δουλεύει  θα του βάλω το Win 2003 Server με το εταιρικό VLK και βλέπουμε… Θα το αποφασίσω στην πράξη αφού δεν μπορώ στη θεωρία…
