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: 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?
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.
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.
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">
3: <div>
4: <asp:Image ID="Image1" src="" runat="server" /><br />
5: <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
6: <asp:Button ID="Button1" runat="server" Text="Button" />
7: </div>
8: </form>
9: </body>
[Code-View]
1: // Page Load
2: protected void Page_Load(object sender, EventArgs e)
3: {4: // Add SRC attribute to Iage1 at runtime
5: Image1.Attributes.Add("src", GetGravatarImageURL(TextBox1.Text.Trim(), 80));
6: } 7: 8: // Return Gravatar Image URL
9: public static string GetGravatarImageURL(string emailId, int imgSize)
10: { 11: 12: string hash = string.Empty;
13: string imageURL = string.Empty;
14: 15: // Convert emailID to lower-case
16: emailId = emailId.ToLower(); 17: 18: hash = FormsAuthentication.HashPasswordForStoringInConfigFile(emailId, "MD5").ToLower();
19: 20: // build Gravatar Image URL
21: imageURL = "http://www.gravatar.com/avatar/" + hash + ".jpg?s=" + imgSize;
22: 23: return imageURL;
24: }Now just run/build(F5) your page. The image will looks like below:
This is the default Gravatar image.
Now just, enter your email Id used for creating the Gravatar account. & hit the button.
Hurray you’re done. Just integrate at the comments section of your blog.
This is my gravatar image
That's it & Thanks.
