How to get time elapsed after loading a webpage

noreply@blogger.com (Unknown) — Sat, 17 Oct 2009 09:50:00 +0000

How to get the time elapsed time after loading a webpage, using Callback() in MS Ajax library. Here is a sample script;

[Ajax-Script]

   1: <script type="text/javascript">

   2:         // Page Load

   3:         function pageLoad() {

   4:             var loadTime = {date : new Date()};

   5:             var callback = Function.createCallback(onBtnClick, loadTime);

6:

   7:             $addHandler($get("Button1"), "click", callback);

   8:         }

9:

  10:         function onBtnClick(event, context) {

  11:             var loadTime = context.date;

  12:             var elapseTime = (new Date() - loadTime) / 1000;

13:

  14:             $get("Text1").value = elapseTime + " Seconds";

  15:         }

  16:     </script>

[HTML-Script]

   1: <form id="form1" runat="server">

   2:     <asp:ScriptManager ID="ScriptManager1" runat="server">

   3:     </asp:ScriptManager>

   4:     <div>

   5:         Time elapsed since PageLoad:

   6:         <input id="Text1" type="text" />

   7:         <input id="Button1" type="button" value="Get Elapsed Time" />

   8:     </div>

   9:     </form>

Thanks.

Sys.ArgumentTypeException: Object of type 'String' cannot be converted to type 'Number'

noreply@blogger.com (Unknown) — Sat, 17 Oct 2009 08:24:00 +0000

Another careless mistake : when I used the setLocation() method in the DomElement class in Sys.UI namespace. I tried to set the location of a DIV element using the value which I read from a textbox and I’s thrown with the error:

Sys.ArgumentTypeException: Object of type 'String' cannot be converted to type 'Number'

After taking a close look, I found it. The setLocation() method clearly states that I’ve to enter the (x,y) coordinates as integer data type. Take a look:

Aaahhh…!!! See how careless I’m. Soon, I fixed the small careless-bug using ParseInt() as

Hope, you’ll be more careful.

Thanks.

Reposition a DOM element using Ajax

noreply@blogger.com (Unknown) — Sat, 17 Oct 2009 08:03:00 +0000

For handling the DOM elements, Microsoft Ajax library has a Class named DomElement in the Sys.UI namespace. The DomElement class has 2 methods as follows:

a) getLocation(element-name): returns the (x,y) coordinate of the DOM element.
b) setLocation(element, x-pos, y-pos): sets the DOM element to (x,y) position.

Here is a simple example on repositioning a DOM element using the Ajax library;

[Ajax Script]

   1: <script type="text/javascript">

   2:         //Page Load

   3:         function pageLoad() {

   4:             var btnGet = $get("btnGetPos");

   5:             var btnSet = $get("btnSetPos");

6:

   7:             $addHandler(btnGet, "click", getXYLocation);

   8:             $addHandler(btnSet, "click", setXYLocation);

9:

10:

  11:         }

12:

  13:         // Get (X,Y) Location

  14:         function getXYLocation() {

  15:             var location = Sys.UI.DomElement.getLocation(div1);

16:

  17:             var tbX = $get("tbXpos");

  18:             var tbY = $get("tbYpos");

19:

  20:             tbX.value = location.x;

  21:             tbY.value = location.y;

  22:         }

23:

  24:         // Set (X,Y) Location

  25:         function setXYLocation() {

  26:             var tbX = $get("tbXpos").value;

  27:             var tbY = $get("tbYpos").value;

28:

  29:             alert(tbX + tbY);

30:

  31:             Sys.UI.DomElement.setLocation(div1, parseInt(tbX), parseInt(tbY));

  32:         }

33:

  34:         // Unload Page

  35:         function pageUnload() {

  36:             var btnGet = $get("btnGetPos");

  37:             var btnSet = $get("btnSetPos");

38:

  39:             $removeHandler(btnGet, "click", getXYLocation);

  40:             $removeHandler(btnSet, "click", setXYLocation);

  41:         }

  42:     </script>

[HTML-Script]

   1: <form id="form1" runat="server">

   2:     <asp:ScriptManager ID="ScriptManager1" runat="server">

   3:     </asp:ScriptManager>

   4:     <div id="div1" style="border: ridge 1px Black; width: 250px; text-align: justify;">

   5:     This is a sample text inside an HTML for demonstrating CSS Positioning using ASP.NET Ajax Library.

   6:     </div>

   7:     <br />

   8:     <div>

   9:     X-Coord: <input id="tbXpos" type="text" /><br />

DomEvents in ASP.NET AJAX

noreply@blogger.com (Unknown) — Sat, 17 Oct 2009 07:46:00 +0000

In my previous article Avoid Numbers in Textbox using ASP.NET AJAX, I showed how you can prevent numbers from being entered into a Textbox, using ASP.NET AJAX Framework.

In that example, the code segment e.charCod and preventDefault() designates a property belonging to Sys.UI.DomEvent class. The Sys.UI is the class provided by the AJAX Framework to work with the DOM components in a webpage. And you can say, Sys is the root namespace or mother-of-all classes, just like System is the root namespace in C#.

After a slight Binging, I’s able to get a lot more properties of the Sys.UI.DomEvent class. Please note, they are cross-browser objects. Here is the list:

Properties	Descriptions
rawEvent	event-data object built by the current browser
shiftKey	Returns TRUE, if SHIFT key was pressed
ctrlKey	Returns TRUE, if CTRL key was pressed
altKey	Returns TRUE, if ALT key was pressed
button	captures the mouse-button click and has values as (leftButton, middleButton and rightButton)
charCode	character code for the typed characters
clientX	returns the x-coordinate of the mouse location relative to client area of the page
clientY	returns the y-coordinate of the mouse location relative to client area of the page
target	represents the Element that raised the event
screenX	x-coordinate of mouse-pointer relative to screen
screenY	y-coordinate of mouse-pointer relative to screen
type	Returns name/type of the event (click/mouse)
preventDefault()	Prevents the default action associated with that event
stopPropagation()	Prevents the event from propagation to the element’s parent nodes

Hope this is handy.
Thanks.

Avoid numbers in Textbox using ASP.NET AJAX

noreply@blogger.com (Unknown) — Thu, 17 Sep 2009 10:56:00 +0000

An old question which was recently asked for an interview.

How can you prevent numbers from being entered into a Textbox, using Microsoft ASP.NET AJAX Framework. Thinking about UpdatePanel’s? Be clever, I have some client-side codes, using the framework itself.

[Client-Side]

   1: <script type="text/javascript">

   2:     function pageLoad() {

   3:         var tbox = $get("Text1");

   4:         $addHandler(tbox, 'keypress', text1_keypress);

   5:     }

6:

   7:     function text1_keypress(e) {

   8:         var code = e.charCode;

   9:         if (code >= 48 && code <= 57)

  10:             e.preventDefault();

  11:     }

12:

  13:     function pageUnload() {

  14:         var tbox = $get("Text1");

  15:         $removeHandler(tbox, 'keypress', text1_keypress);

  16:     }

  17: </script>

[Markup-Code]

   1: <form id="form1" runat="server">

   2: <asp:ScriptManager ID="ScriptManager1" runat="server">

   3: </asp:ScriptManager>

   4: <div>

   5:     Enter text value:

   6:     <input id="Text1" type="text" />

   7: </div>

   8: </form>

Thanks.

What are Mashups?

noreply@blogger.com (Unknown) — Thu, 17 Sep 2009 05:27:00 +0000

It’s been a long time, I’ve been hearing about mashups in the web world. Surprisingly, I came across the same when I’s reading Manning’s ASP.NET AJAX in Action.

A mashup is a web application that consumes content from more than
one external source and aggregates it into a seamless, interactive experience
for the user.

If you ask me a live example, here it is PageFlakes.

Exiting an Application on Error

noreply@blogger.com (Unknown) — Tue, 15 Sep 2009 10:23:00 +0000

Error handling is always a nightmare for every programmer. Because, testing you application in your development lab and exposing the application to a real-world lies in two extremities. The very reason where everyone go for alpha/beta and finally the RC release. Hey…Hey…I’m not going into core-concepts.

Recently, I’s re-optimizing a 6-month old c#-code (written in .NET 2.0) to .NET 3.5. Re-optimizing the code is a tough task, specially when the code was written by someone else. It deals with studying the code, understanding the logic and also good, if you can preview the test-cases encountered while re-designing.

When digging deep into the logic, I came across code-blocks where, even if you catch an Exception, you can’t continue because that might cause an abnormal exception at some other point. Huh! and I’s forced to kill the application at that point, using one-line code.

1:

   2: Environment.Exit(1);

3:

Remember, use this code safely. Use it only when you came across a do-or-die situation. Killing an application unnecessarily is bad way of programming.

Happy Programming.

Simple Checksum Generation in .NET

noreply@blogger.com (Unknown) — Fri, 28 Aug 2009 09:12:00 +0000

.NET framework is a tremendous installment from MSFT. No doubt! Every day-to-day life methodologies are wrapped into a Namespace/Class form. Say, Mail Sending class (System.Net.Mail), and so on. With the release of .NET 3.0, the number of Namespace/Class simply grew and they’ll.

A major installment in .NET 3.0 was Lambda Expressions. That even reduced the Line of Codes(LOC). In a nutshell, Lambda expression converts a bunch of codes into a single line of code, which we(I) may call as one-liner codes. Hard to believe, wait!

How, it affected a programmer? Does it made their work easier or does it made them lazy? Anyway, it made me lazy a bit. Because, whenever I start to implement repeating/familiar codes, say Checking Odd/Even values, etc, I always look for one-liners. Because, I don't want to repeat the same LOC every time. But, its better to know, what’s the internal implementation of one-liner, for Performance and Optimization reasons.

Recently, I’s developing an application for one of my client, in which I’ve to implement a checksum feature for a 9-Digit UniqueID (generated from another code-block).

The checksum technique was simple. My checksum has 3-Digits;
a) 1st Digit = Total Sum (of 9 Digits)
b) 2nd Digit = Even Sum (sums up the digits in the even place)
c) 3rd Digit = Odd Sum (sums up digits in the odd place)

Please note, Chances are that the Total Sum, Even Sum or Odd Sum may have 2 Digits, which you’ve to sum up again to a single digit.

The traditional mode of generating Even Sum, Odd Sum and Total Sum deals with a lot of mathematical computations and all, which is quite tedious to repeat every time. Here comes Lambda Expression, as a handy feature in .NET 3.0.

Here is the code segment for :

a) Total Sum

   1: int totSum = uniqueId.ToString().Sum(c => c - '0');

b) Even Sum

   1: bool flag = false;

   2: int evenSum = uniqueId.ToString().Sum(c => (flag = !flag) ? 0 : c - '0');

c) Odd Sum

   1: bool flag = false;

   2: int oddSum = uniqueId.ToString().Sum(c => (flag = !flag) ? c - '0' : 0);

I bet, this is quite handy.

Changing Multiple GridView Row values using RowUpdating event

noreply@blogger.com (Unknown) — Sat, 08 Aug 2009 01:31:00 +0000

This is an extended sample of my previous post titled Change GridView Row values using RowUpdating Event. Recently, I got comment from NobleMule asking how he can edit multiple column/cell values.

“I have 4 DDL's in a gridview. The first one is updating (mostly thanks to your code) but I can't get the other three to update. I'm a fairly new to C# and have never used the DictionaryEntry before. I naively tried just adding more if's (one for each ddl) within the foreach loop but that didn't work. Any help would be greatly appreciated.”

I hope the 4 DDL’s are in 4 different Cells of a GridView. And wants to update the new values selected in those DDL’s into the database. As he’d mentioned my previous post sample is only meant for updating the DDL present in one Cell of your GridView.

I’ll break-up the concept here, so that you can deal with any number of Cells in the GridView. These are the tips to be kept in mind before start coding.

#1. Identify the Row in the GridView for updating, obtained via e.RowIndex

#2. Identify the Cell (column) in the GridView for updating.
This value will be entered manually. Keep in mind, Cell indexing starts from zero.

#3. Locate the control (DDL here) using FindControl() method and cast it to appropriate type (ie, DDL type here).

These tips help you to find a Control in a particular (row,cell) of a GridView.

Now, the real case. You want to update the DDL in 4 different Cells of a GridView. All you’ve to do is to:
(a) Identify each Cell of GridView
(b) Access the Control (DDL here), from each Cell
(c) Get the Selected Value from DDL
(d) Update with new value

Lets assume that we’ve a Table having cells as:

Column1

Column2

Column3

Column4

And, Column1 having DropDownList1, Column2 having DropDownList2, Column3 having DropDownList3 and Column4 having DropDownList4.

Now, the rough piece of code looks like:

1:

   2: protected void GridView1_RowUpdating(object sender, GridViewUpdateEventArgs e)

   3:     {

   4:         foreach (DictionaryEntry entry in e.NewValues)

   5:         {

   6:             DropDownList ddl;

7:

   8:             if (entry.Key.ToString() == "Column1")

   9:             {

  10:                 ddl = (DropDownList)GridView1.Rows[e.RowIndex].Cells[1].FindControl("DropDownList1");

  11:                 e.NewValues[entry.Key] = Server.HtmlEncode(ddl.SelectedItem.Text);

  12:             }

  13:             if (entry.Key.ToString() == "Column2")

  14:             {

  15:                 ddl = (DropDownList)GridView1.Rows[e.RowIndex].Cells[2].FindControl("DropDownList2");

  16:                 e.NewValues[entry.Key] = Server.HtmlEncode(ddl.SelectedItem.Text);

  17:             }

  18:             if (entry.Key.ToString() == "Column3")

  19:             {

  20:                 ddl = (DropDownList)GridView1.Rows[e.RowIndex].Cells[3].FindControl("DropDownList3");

  21:                 e.NewValues[entry.Key] = Server.HtmlEncode(ddl.SelectedItem.Text);

  22:             }

  23:             if (entry.Key.ToString() == "Column4")

  24:             {

  25:                 ddl = (DropDownList)GridView1.Rows[e.RowIndex].Cells[4].FindControl("DropDownList4");

  26:                 e.NewValues[entry.Key] = Server.HtmlEncode(ddl.SelectedItem.Text);

  27:             }

  28:         }

  29:     }

Hope this makes some sense.

Thanks.

How to get Duplicate records in a Table

noreply@blogger.com (Unknown) — Fri, 26 Jun 2009 09:49:00 +0000

Last day, I seamlessly entered into a situation where I want to list out all the repeating/duplicate records from a table. Though it sounds simple, its bit a tricky approach.

As a small example: consider a table say RepeatTest having 2 fields: Id and Url. To figure out the repeating Url records, you can write the query as:

1:

   2: SELECT Url, count(Url) FROM RepeatTest

   3:     GROUP BY Url

   4:         HAVING (COUNT(Url)>1)

5:

Sometimes you may also jump into sudden simple queries, as what I’d jumped into.

Update: This simple question was asked for the Huwaei International's written exam, held at Bangalore on July 2009.

Automatic Implemented Properties in .NET 3.5

noreply@blogger.com (Unknown) — Thu, 25 Jun 2009 18:02:00 +0000

One of the cool feature that I like in .NET 3.5 is the automatic implementation of Properties in .NET 3.5. Here is a sample:

1:

   2: private string _name

3:

   4: public string Name

   5: {

   6:     get

   7:     {

   8:         return _name;

   9:     }

  10:     set

  11:     {

  12:         _name = value;

  13:     }

  14: }

Can be re-written as:

1:

   2: public string Name {get; set;}

3:

Operation aborted in IE8

noreply@blogger.com (Unknown) — Sat, 20 Jun 2009 06:04:00 +0000

Dear Readers/Visitors, as you might know you may receive an “Operation Aborted” error message, when visiting my blog using Internet Explorer. Honestly, I don't know what had happened. How sad. (I’m an IE Lover…!!!).

I’ve posted the issue in IE MSDN Forum. Though they helped, but was not solved completely. Also, they have provided some troubleshooting methods to solve the issue. If you are experiencing the same problem of “Operation Aborted” exception, then have a look at the discussion here.

Thanks.

Update: I think the problem is solved now. I'm not getting the error message. What about you guys?

jQuery quick notes

noreply@blogger.com (Unknown) — Sat, 09 May 2009 12:34:00 +0000

Here is some quick notes while handling jQuery.

   1: // Locates all elements with type=Text

   2: $("input[type=text]")

3:

   4: // Selects all <div> element with 'title' attributes

   5: // whose value begins with 'my'

   6: $("div[title^=my]")

7:

   8: // Locates all links that refers PDF

   9: $("a[href$=.pdf]")

10:

  11: // Locates anchor elements having the value

  12: // someurl.com anywhere in the 'href' attribute

  13: $("a[href*=someurl.com]")

14:

  15: // Locates all the achor tags

  16: // coming inside a li tag

  17: $("li:has(a)")

18:

  19: // Locates anchor(a) tags inside a paragraph(p) tag

  20: // where anchor-tag having a cssClass="someCssClass"

  21: $("p a.someCssClass")

22:

  23: // Matches all anchor(a) tags

  24: $("a")

25:

  26: // Matches element having an id=someId

  27: $("a#someId")

28:

  29: // Matches all elements having a CssClass=someCssClass

  30: $(".someCssClass")

31:

  32: // Locates anchor(a) tag with Id=someId and cssClass=someCssClass

  33: $("a.someId.someCssClass")

Reference: Manning’s jQuery in Action.

I must say, it’s a must read book.

Thanks.

No jQuery intellisense in Visual Studio Workaround

noreply@blogger.com (Unknown) — Fri, 08 May 2009 10:34:00 +0000

If you are using jQuery 1.3.2 in Visual Studio 2008 or Visual Web Developer 2008 (SP1), you may come across scenario where you wont get the jQuery intellisense support, even if you add jquery-1.3.2-vsdoc2.js file to the aspx page.

The workaround is simple. All you’ve to do, is to rename the jquery-1.3.2-vsdoc2.js to jquery-1.3.2-vsdoc.js.

It looks like:

   1: <script src="Scripts/jquery-1.3.2.js" type="text/javascript"></script>

   2: <script src="Scripts/jquery-1.3.2-vsdoc.js" type="text/javascript"></script>

Note: For making VS/VWD to support jQuery intellisense, you’ve to apply a patch from the VS Development team & can be downloaded from here.

Gravatar using ASP.NET

noreply@blogger.com (Unknown) — Thu, 30 Apr 2009 10:43:00 +0000

I’m always attracted with the fancy features in web. This time, I fall in love with Gravatar. Its a global recognition of “YOU”, with the help of an e-mail Id.

If you don't have a Gravatar account, create on here.

The SRC attribute a Gravatar Image has the below mentioned syntax:

http://www.gravatar.com/avatar/[MD5_Hash_Value]?s=[Image_Size]

For loading your Gravatar image, all you’ve to do is to mention the Hash Value of your email id and the size of your Gravatar image.

Before start, drag-drop an Image control, TextBox (for accepting email Id) and Button control.

[Source-View]

   1: <body>

   2:     <form id="form1" runat="server">

FF3 Ad over IE

noreply@blogger.com (Unknown) — Wed, 22 Apr 2009 09:49:00 +0000

Does anyone noticed this?

http://www.mozilla.com/en-US/firefox/ie.html

See, the courage, confidence and power of Mozilla corporation; directly advertising over IE. Nothing to say more, IE market-share dipped to 66%. But, this time IE is losing the market-share in a quicker pace. IE8 have to struggle a lot to gain the market again and again.

Good luck, IE.

BTW, I’m an addicted IE user.

Inserting selected attribute values into a Table

noreply@blogger.com (Unknown) — Thu, 02 Apr 2009 10:33:00 +0000

Just imagine you’ve five fields (columns) in table & you only want to insert 2 values (say, in Col2 & Col3) of the table; then use as follows:

   1: INSERT INTO Table_Name (Col2_Name, Col3_Name)

   2:     VALUES (Col2_Value, Col3_Value)

Programmatically accessing RSS Feed using RSSToolkit Control

noreply@blogger.com (Unknown) — Wed, 01 Apr 2009 12:25:00 +0000

An awesome RSS Feed control (Dmitry’s RSSToolkit) was released years before, I came to knew about ASP.NET.

Last months, I’s spending some time with the control. I must say, its really cool. One problem I encountered; lack of documentation (or my lack of knowledge), What ever it may. But, it was really nice to write some cool codes using the control.

Ok! In this article, I’ll show small piece of codes demonstrating how to retrieve RSS Feeds from sites programmatically.

Before we start, please download RSSToolkit 2.0 from codeplex, and add the control to your Visual Studio toolbox (?).

Step 1: Drag-drop ‘RssDataSource’ control from your toolbox to the webpage.

Now just keep an eye on the source-view. When you drag-drop the RssDataSource, you’ll get a Register tag in the source-view like:

<%@ Register assembly="RssToolkit" namespace="RssToolkit.Web.WebControls" tagprefix="cc1" %>

Step 2: Drag-drop a TextBox for accepting the feed-url.

Step 3: Drag-drop a Button to trigger fetching the feeds. Double-Click the button to generate the Click event.

Step 4: Drag-drop a Label control to show an error when you enter an invalid feed-url.

[Design-View]

[Source-View]

<body>
    <form id="form1" runat="server">
<div>
        <cc1:RssDataSource ID="RssDataSource1" runat="server">
        </cc1:RssDataSource>
        <br />
        Enter Feed URL: <asp:TextBox ID="TextBox1" runat="server" Width="300px"></asp:TextBox>
        <asp:Button ID="Button1" runat="server" onclick="Button1_Click" Text="Fetch" />
        <br />
        <asp:Label ID="Label1" runat="server" Font-Bold="True" ForeColor="#FF3300"></asp:Label>
    </div>
    </form>
</body>

[Code-View]

using RssToolkit.Rss;

// Fecth RSS
    protected void Button1_Click(object sender, EventArgs e)
    {
        string feedData = string.Empty;
// Accepts Feed URL
        RssDataSource1.Url = TextBox1.Text.Trim();

        try
        {
            // Iterate through the RSS feed Items
            foreach (RssItem item in RssDataSource1.Rss.Channel.Items)
            {
                // Feed Author
                feedData = item.Author;
                // Feed Title
                feedData = item.Title;
                // Feed Link
                feedData = item.Link;
                // Feed Description
                feedData = item.Description;
                // Feed Publish Date
                feedData = item.PubDate;

                // Print the output
                Response.Write(feedData + "<br/><hr/><br/>");
            }
        }
        catch (UriFormatException exp)
        {
            Label1.Text = "Invalid Feed URL";
        }
    }

[Demonstration]
a) copy the url of an RSS feed, say http://feeds2.feedburner.com/DidYouSaynet.

b) Paste it on the TextBox & Hit the button. That's all.

c) See How the feeds are displayed.

Hoping it will help someone.

Note:

a) Do not forget to include the namespace using RSSToolkit.RSS.

b) One of the common question you may encounter is how to fetch feeds with a count limit?. That means you only want to fetch last 3 feeds, 5 feeds, etc. At this point I don't have the answer. Even though the RSSDataSource has a property named MaxItems ( where you can set the feed limit), it was not working when tried programmatically. Only way I believe you can do; is to insert a count value in the foreach statement & break the loop when you feed-count limit is reached.

c) Next question will be how can I download updated feeds only from a site?. The answer will be my next post.

Also you can find some cool articles of RSSToolkit @ ScottGu’s blog and @ CodeProject, which inspired me to write this.

Thanks for taking time to read the post.
