I created a test ASP.net web page with a button on it and used the following code to retrieve to the web page you wanted. what you would have to do is parse through the string, "lcHtml", which contains the table data.

Good luck.

Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click

       Dim myURL As String = "http://www.moneycontrol.com/stocks/marketstats/mostactive.php?optex=NSE&index=31&opttopic=mostactive"

       ' *** Establish the request

       Dim loHttp As HttpWebRequest


       loHttp = WebRequest.Create(myURL)

       ' *** Set properties

       loHttp.Timeout = 10000     ' 10 secs
       loHttp.UserAgent = "Code Sample Web Client"

       ' *** Retrieve request info headers

       Dim loWebResponse As HttpWebResponse
       loWebResponse = loHttp.GetResponse()

       Dim enc As Encoding

       enc = Encoding.GetEncoding(1252)  ' Windows default Code Page

       Dim loResponseStream As New StreamReader(loWebResponse.GetResponseStream(), enc)

       Dim lcHtml As String

       lcHtml = loResponseStream.ReadToEnd()

       loWebResponse.Close()

       loResponseStream.Close()

       Response.Write(lcHtml)

       'System.Diagnostics.Debug.WriteLine(lcHtml)


   End Sub

At this time, I have no time to work on such a project. I'm busy at work and home. I find this project interesting, so I may work on it for my own knowledge, but I can't guarantee any timeframe for completion.

Unble to write files to a folder in ASP.NET application.

Hi All,

I am having one ASP.NET application in which I m trying to write multiple files in folder (C:\Inetpub\wwwroot\Test\MyData\reports). I am failed to write files in folder if I omit the write permission to Everyone.

I do not want to give Everyone permission due to security reasons. I am using windows XP and IIS 5.1 but my client can use different os such as Windows 2000, 20003 etc and different IIS 5.x or 6.0. So I need a solution which will work on all the platforms.

I tried to find out the correct way for achieving this but found no correct solution. Tried following things:

1. I have given Full permission to 'reports' folder for ASPNET account using security tab, but it didnt work.Same thing I tried with IIS_WPG but it is also not working.

2. I have read about impersonation but I think it is not suitable for my requirement as I do not want to give permission for a specific user and also I can not instruct the client to change user name and password in web.config.

3. One thing which worked in my case is when I given write permission to 'Users(<machinename>\Users)' group using security tab. I dont know how it worked or is it the correct solution and if yes, then will it wiork for different OS and IIS.

Thanks in advance for any help.

Regards,
NN

I would guess that you're getting newlines in your text, but you need to replace them with break tags if you want to render the text onto your page.

.Replace(Environment.NewLine, "<br/>"); on the string before you render it. Or before you store it.

you have to insure the drop down property AutoPost back is true

Rubbish. If he's got a button set to do the postback, that will work just fine, and if he has a problem, AutoPostback won't fix it.

well changing the selected item in the dropdownlist and causing a postback on that event might be the solution i guess

Not a chance in hell. If it gets lost, it will still get lost on an autopostback

Christian Graus9-Jun-09 21:20

Re: value is not getting in dropdown after a button click

Odds are good that you're binding to your data source every time. This will clear the selection. So, bind your drop down to your data source in an if (!IsPostback) block.

I Guess, this is due to postback while storing and loading data from database. Unless you post the relevant code its difficult to say.

Static Varible Sharing Problem

Hai Friends

I have declared a variable outside all the function in an aspx.cs page, like

public partial class StaticVar : System.Web.UI.Page
 {

    static int a;

    protected void Page_Load(object sender, EventArgs e)
    {

        Response.Write(a.ToString());
    }
    protected void Button1_Click(object sender, EventArgs e)
    {
        a = 50;
        Response.Write("set 50, a= " + a.ToString());
    }
    protected void Button2_Click(object sender, EventArgs e)
    {
        a = 60;
        Response.Write("set 60, a= " + a.ToString());
    }
    protected void Button3_Click(object sender, EventArgs e)
    {
        Response.Write("a= " + a.ToString());
    }
}

The problem is that when more than one user access this page and modifies the variable a, all the users gets the new value for a,
i.e., they loose the value what they had set for a. They get the value that is been set by the last user.

If I remove 'Static' from its declaration, then its value is not available to other functions.

How to solve this problem.
Please help me.

Buy a basic book on ASP.NET and read it. Actually, I suspect your issue is that you don't understand ASP.NET. Static works just as you are seeing, and non static only exists for the lifecycle of one page. Therefore, you need to store values in something persistent, such as the session, or if it's all in one page, viewstate.

There is no need to declare it static if you are declaring it as class level variable. As a class level variable, it's value should be accessible in all methods inside that class.

If I don't declare it as Static, then its value is retained only in the function in which it is assigned. In other function its value becomes 0. Please check my code without Static identifier.

The issue is that without the static the variable is only available for that one instance of the page. Every time you visit the page you get a new instance of the page so the variable is set back to what it started as.

Your mental model is that when a user gets a page they retain that page object for the duration of their session. They don't. That would place an huge strain on the server to maintain all that for all users.

A page will be destroyed soon after it is rendered - along with all variables on it.
