Hey,

Hope i understood you question!! If not, correct me.

Infact, you need to display the ID value in repeater control for some reasons (to be captured in javascript or so). For that, you have to apply CSS.

Thanks,

Hi guys,
I'm developing a small site for someone who made the mistake of hosting with GoDaddy. I am unable to make any outbound connections for WebRequest and stuff from Godaddy.

<br />
<br />
String strResult;<br />
<br />
WebResponse objResponse;<br />
<br />
WebRequest objRequest =<br />
System.Net.HttpWebRequest.Create("http://www.google.com");<br />
<br />
objRequest.Proxy = new<br />
WebProxy("https://64.202.165.130:3128");<br />
<br />
//objRequest.Proxy = new<br />
WebProxy("https://64.202.165.130:3128");<br />
<br />
//objRequest.Proxy = new<br />
WebProxy("http://wc-v01.inet.mesa1.gdg:3128");<br />
<br />
//objRequest.Proxy = new<br />
WebProxy("https://wc-v01.inet.mesa1.gdg:3128");<br />
<br />
objResponse = objRequest.GetResponse();<br />
<br />
// the using keyword will automatically<br />
dispose the object <br />
<br />
// once complete<br />
<br />
using (StreamReader sr = new<br />
StreamReader(objResponse.GetResponseStream()))<br />
<br />
{<br />
<br />
strResult = sr.ReadToEnd();<br />
<br />
// Close and clean up the<br />
StreamReader<br />
<br />
sr.Close();<br />
<br />
}<br />
<br />
Response.Write(strResult);<br />
<br />

I used that code to test f I could make outbound connections. On my IIS it worked fine but when I uploaded it gave "Could not connect kind of error". I did comment out all the Proxy code when I ran it on my IIS. GoDaddy has a Proxy server. I've tried all combinations to make it work but it doesn't. GoDaddy claims its a coding error. Is there a simpler code to test whether I ca n make outbound connections froma particular server or something.

What do you mean by "doesn't work" exactly? What happens? Doesn't it draw the way that you expected? Do you get an error message? Does the computer crash and burn?

Use Server.MapPath to get the physical address from your virtual address, so that the image is saved in the web folder. Otherwise it's saved in the work directory of the ASP.NET enginge, which probably is something like "c:\Windows\System32\".

What do you mean by section in this case?

If you want the variable to be local to the object, just remove the Shared keyword.

Oh, so by "setion", you mean session, not section?

If you remove the Shared keyword, the variable will be local to the object, and therefore also local to the thread. Each request that comes to the server is handled in a separate thread.

If you want to keep the value from one request to another, on a user basis, you have to use session variables or cookies.

You create a session variable by adding a value to the collection:

Session["answer"] = 42;

As session variables are of type object, you have to cast them to the correct type when you read them:

int answer = (int)Session["answer"];

You can remove a variable from the collection:

Session.Remove("answer");

You can also remove all variables:

Session.RemoveAll();

Encapsulate your control in a DIV so that your problem would be resolved

Hi I developed a web application using 1280x1024 resolution. But the end user uses a different resolution which makes the page go into horizontal and vertical scrolls. Is there anyway I can make my webapp to resize based on user screen resolution?

textbox validation please help

HI,
I have some text in a textbox that is reading directly from a database. My application is supposed to allow user to update this text, so it directly affects in the database content.

Now in my text there are some special characters like : , ' href < >. The code works fine as long as the text data in the text box does not contain these characters. As soon as it encounters data with these characters it does not update the database, any suggestions to tackle this. I already tried, <pages validaterequest="false"> in web.config with no success

It would be helpful if you described exactly what is happening, not just what is not happening.

Thanks for the response

I have text box reading text content from database. When I change the text in the textbox and do update, it does not update in the database. I traced the problem to special characters like : and ' in the text field. When the text in the text field does not contain these special characters, it works fine. How to get around these special characters?

You don't have to get around any characters, you just have to treat them properly.

What do you do to update the database? What method are you using? Do you create an SQL query yourself? Do you use a parameterised query or do you concatenate the values into the query?

I see no reason why a colon would be any problematic, but an apostrophe is a common problem if you concatenate strings into the query and don't encode the data properly first.
