ASP.NET Discussion Boards

I'm busy coding a page to get assorted statistics from different places, and displaying them in an easy-to-read format...

My question is this:

Is it possible to get the Source of a website?

Not the Source-Code, as such, but just the raw data?

Maybe something like....

StreamReader sr = new StreamReader("http://www.codeproject.com/");
string theText = sr.ReadToEnd();
textBox1.Text += theText;

Result:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

<html>

<head>
<title>CodeProject. Free source code and programming help</title>

<meta http-equiv="Content-Type" content="text/html; charset=utf-8" >
<meta name="Description" content="Free source code and tutorials for Software developers and Architects." >
<meta name="Keywords" content="Free source code, tutorials" >

</html>

Any suggestions?

You can get the source of any page by using a the HTTP methods in a winforms app. You can't do it using ASP.NET. This is different from the actual source that runs the site, obviously, it's the HTML that is generated on a particular day.

You can't do it using ASP.NET <---

Frown | :(

And yes, I just want the generated HTML - The .cs / code-behind pages can remain hidden all they want Poke tongue | ;-P

Oh, and a google search for:

"C#"+"ASP.NET"+Code

doesnt really help, as you might imagine Wink | ;)

Perhaps because ASP.NET has nothing to do with your question ? You can't write a web site, a bunch of code that generates HTML, and expect that code, in that framework, to browse the web stealing HTML from other sites. This is a winforms question.

StreamReader takes physical paths, I believe. Did you try using WebRequest?

Success!

Thanks to WebRequest!

string result = "http://www.codeproject.com/";<br />
        HttpWebRequest loHttp = (HttpWebRequest)WebRequest.Create(result);<br />
<br />
        HttpWebResponse loWebResponse = (HttpWebResponse)loHttp.GetResponse();<br />
<br />
        StreamReader loResponseStream = new StreamReader(loWebResponse.GetResponseStream());<br />
<br />
        string tmp = loResponseStream.ReadLine();<br />
        while (tmp != null)<br />
        {<br />
            ListBox1.Items.Add(tmp);<br />
            tmp = loResponseStream.ReadLine();<br />
        }<br />
<br />
        loWebResponse.Close();<br />
        loResponseStream.Close();

Thanks for the help Big Grin | :-D

Hi,
In my project I have 3 forms. Home.aspx, CreateInfo.aspx and CreateInfoNext.aspx. CreateInfo and CreateInfoNext I have defined Back link button. when click on back link button it display previous page.
this working fine. but my problem is I have some validators in each page.
am validating on server side and displaying it under ValidationSummery field validator. If I gave some thing wrong in one field and click on Next button, it is validating and showing error and it is not forwarding to other page.Its OK. Now I entered right text and click on next button it is validating and going to other page. This is ok. the real problem is when I click back button it should go to previous page.it is going but showing error messages under ValidationSummery field validator.

pls see the follwing code:

<asp:LinkButton CausesValidation="false" ID="linkButtonBack" CssClass="linkbold" PostBackUrl="javascript:history.back();" runat="server">< <%=resourceManager.GetString("CMN_TOP_BACK")%></asp:LinkButton>

pls help me in this.

Thanks

Heh... I had the same problem...

I changed all my RequiredField validators to Red Label's, and manually checked them...

RangeValidators were more... Interesting...

if the RangeValidator is checking textBox1 for a value, just go:

textBox1.Text = "";<br />
Response.Redirect("www.google.co.za"); // Replacing with whatever

Since the textBox is empty, the RangeValidator is ignored...

Although, if you find some OTHER way to do this (Possibly keeping the RequiredField Validators), please give me a yell Sigh | :sigh:

Hi Everyone,
In my application i am using Label and DropdropList, on the selection of Dropdownlist,the label is disappear from the Form.

i am using like this

<div>
<asp:label id="L_Country" runat="server" />
</div>

<div>
<asp:ropDownList ID="DDL_LCD_Country" runat="server" OnSelectedIndexChanged="DDL_LCD_Country_SelectedIndexChanged"
AutoPostBack="true" >
<asp:ListItem Text="Select Country"></asp:ListItem>

</asp:DropDownList>
</div>

Please help me, where i am making mistake.

Well, first you've not shown any code that will hide the label. Second, do you NEED to do an autopostback, or is that only to hide the label ? If you need to postback anyhow, then in DDL_LCD_Country_SelectedIndexChanged, set L_Country.Visible = false. BTW, your naming standard is really nasty, does a company enforce that ?

If you don't need the postback, do it in javascript.

What you are doing in the "DDL_LCD_Country_SelectedIndexChanged"?

try
{
foreach (DataRow row in tableRows)
{
[some codings.......................]

label1:
foreach (DataColumn dc in tableColumns)
{
[some codings.......................]
}
}

[some codings.......................]
}
catch (SqlException ae)
{
[some codings.......................]
goto label1;
}

finally
{
CloseConnection();
}

while executing the above.. i m getting error like "No such label 'label1' within the scope of the goto statement"

how to achieve it? - KARAN

well, you've found out for yourself just how nasty code can get when you use goto.

1 - you don't have a label called label1 in this code
2 - I see no reason for you to use a goto here, in any case.

I have never used goto in code, not once. I have also never written code to avoid goto. I have instead avoided some nasty constructs.

goto is unstructured programming. You may need to consider revising your design for better programming constructs instead.

how to overcome it...?
actually i want to pass my control from catch block to for loop as i mentioned in my code....

Woudn't a continue to take to the next iteration of the loop accompanied by an if condition to check for statements from the start of the loop to the current label position help you out?

Do you know how I can link scrollbars of two textboxes. What I need to do, is to move the scrollbar of textbox1 when the scrollbar of textbox2 is moved and visa vesa.

You'd need to check if you can catch a scroll event on a textbox in javascript, then when one scrolls, scroll the other one if it's not at the same scroll pos. You need to check first tho, or you risk creating an endless loop

Hi All,

What are the datatypes that can be supported in developing web serivces. Means what datatypes of .net I can use to develop web services.

How can I display a Modal Popup window in ASP.Net using vb.net 2005. I had used the code bellow to show a popup window.

ClientScript.RegisterStartupScript(Me.GetType, "popup", "window.showModalDialog('abc.aspx','_blank','height=450px,width=625px,menubar=no');", True)

But this code creates a problem i.e., when i click on a button on the popup window it again displays the same form in another window non modally. And if i open the window non modally i.e., using the code bellow i dont get any errors.

ClientScript.RegisterStartupScript(Me.GetType, "popup", "window.open('abc.aspx','_blank','height=450px,width=625px,menubar=no');", True)

Please Help how to prevent this.

Thanks in advance.
