I am using the AJAX tab control on a page and it contains a DropDownList which is populated at runtime. When the page is refreshed at postback, the Dropdownlist is cleared. The Viewstate property is ON for DDL and the page. I am unable to understand why is this happening.
I have tried by putting the DDL outsite the Tabs with no luck.

Ask this in the ASP.NET forum. You're question has nothing to do with VB.NET, even if it was the language you used to write the code in.

hi
friends
i have a peculair situation here.
i need to access the web page content from the internet explorer from my vb.net application.
previously i have done an application which takes url and parses it's content. this was damn easier. but the real shock was i got a thought that y cannot i access the web page content from the internet explorer without the url involved.
clear explanation
i open an ie browser. type in a url say "www.google.com" and the page loads into my browser. now i need to write an application in vb.net which can access the webpage content , here it's google webpage content(ie html content)
in short i need to do what ie provides(right click>view source)through my coding
there is no such thing as good or bad.

yup
i have created a browser application in vb.net which just works like the ie browser. i placed a buuton at the menu bar which works exactly like the (right click>view source) way.
but the thing is i need to find a way to do it in the same way with the ie browser. here i want to do it from my vb.net application
there is no such thing as good or bad.

If you created a browser application, then you've already put a WebBrowser control on your form, correct? If so, you've already got the HTML source once the page is downloaded, just look in it's DocumentText property.

i donnot require the url. see friend
if i type in the url in the webpage, the site is diplayed. now for ie browser. if we right click and select view source. we can see the source code. this technique(rightclick>view source) i need to impliment in my application. that means i need to do the same thing via my application instead of doin what ie has provided
there is no such thing as good or bad.

I didn't say you did. I said the HttpWebRequest class would only need the URL so it could download teh source.

u r true dave
bu the thing is how can i implement the " view source " technique just as a ie does. cause. i have used all the techniques. but in vain. we require a url to get the content. but the thing is without the url i need to do this.
there is no such thing as good or bad.

I've given you the only two options you have for getting the source. You seem to be ignoring what I'm saying.
You either have to download the page using the HttpWebRequest, or you have to look at the DocumentText property of the WebBrowser control you used to download the page.

thnaks for that dave.
have completed the task. have done it in vb.net windows application.
but now a new task has come into being. taking the textfile data and put it in the tables
there is no such thing as good or bad.

i place the belove code in my component
Imports System.ComponentModel
<category("button"), description("gets="" or="" sets="" the="" text="" of="" button.")=""> _
Public Property buttonText() As String
Get
Return _Text
End Get
Set(ByVal Value As String)
_Text = Value
End Set
End Property
<category("button"), description("gets="" or="" sets="" the="" tagof="" button.")=""> _
Public Property buttonTag() As String
Get
Return _Tag
End Get
Set(ByVal Value As String)
_Tag = Value
End Set
End Property
But it is not grouping the buttontag and button text property.Anything additionally i want to add

Hi, if You want to group properties You can use the Category-Attribute --> e.g.:
<Category("MyPersonalCategory")> _
Public Property buttonText() As String
Get
Return _Text
End Get
Set(ByVal Value As String)
_Text = Value
End Set
End Property

If you're going to post code with < and > characters in it, make sure you check the box that says "Ignore HTML tags in this message (good for code snippets)" before you click the "Post Message" button.

Hi all,
I am working on an application that is ever growing in functionality. I have started writing it a couple of years ago. To simplify coding, I have also created several small classes that allow me to manipulate strings and such, which I can then call from the rest of the code.
When calling a standard .NET class in the code editor, you usually get a short explanation of what a certain property does, when you leave it selected.
Can anyone tell me whether it is at all possible to mimic this with self made classes, and if yes, then how?
A simplified example:
Public Class DateString<br />
Inherits System.ComponentModel.Component<br />
Public Shared ReadOnly Property ToDayLong() As String<br />
Get<br />
Return LongNumber(Now.Day)<br />
End Get<br />
End Property<br />
Public Shared Function LongNumber(ByVal value As String) As String<br />
If Len(value) < 2 Then<br />
LongNumber = "0" & value<br />
Else<br />
LongNumber = value<br />
End If<br />
End Function<br />
End Class
Where / how should I write the explanation?
All suggestions appreciated.

In C#, you put three / for a comment, so instead of //, it's ///, then it autopopulates with all the stuff you can fill out for auto generated docs and also the intellisense. I'm not sure what it is for VB.

Hi Christian,
Thanks for the suggestion. I had forgotten that it is called intellisense. I just looked it up, and unfortunately it apparently is not supported in VB at all. I guess I'll just rely on the good old gray matter. 
Thanks anyway though,
Johan

Hi friend,
We can write comments by using single quotes. For example : -
Public sub getMax()
'This is to get maximum number
Useful codes.
End Sub
OK. Waiting for next question.

Okay friend...
I am sure your IQ is twice as high as mine, but I am also sure that my question was not that unclear.

If this is VB 2005, type the comment character three times and then press enter in front of the class or method. It will produce an XML comment block. The stuff you type in the summary element is what appears
VB 2003 does not support XML comments unless you install the VB Commenter add-in.
Here's a VB 2005 example from a method I wrote:
''' <summary>
''' Converts a database column value to a nullable type instance.
''' </summary>
''' <typeparam name="T">A generic value Type. See generic constraint in function signature.</typeparam>
''' <param name="dbValue">The database column value.</param>
''' <returns>An instance of a nullable type containing the underlying database column value.</returns>
''' <exception cref="System.ArgumentException"></exception>
''' <remarks>A database null (DBNull) is converted to null (Nothing in VB).</remarks>

Hi Kevin,
Nice one, thanks. I am indeed still on 2003, so I am going to go and play around with the VB Commenter, and switch to 2005 asap.
Cheers,
Johan
