What you need to do is to first get the data from the database and then create a string with the data from the database and display the string. There can be other methods also to display the data depending upon the requirement.

Thanks. but I want to display that data in a pop up window. I have used
button1.attributes.add("onclick","window.open("onclick", "window.open('Result.aspx?r=" +re+ "',null,'height=250, width=650,status= no,resizable= no, scrollbars=no, top=0,toolbar=no,location=no,menubar=no ');");
it is not fired when I click a button. if I click twice it opens result.aspx window. but I need to open in a single click. any solution.?
Thanks

You have window.open twice that is not required. You write like this, I think after this your problem will be solved.
<br />
Button1.Attributes.Add("onclick","window.open('Directory.aspx?r=" +re+ "',null,'height=250, width=650,status= no,resizable= no, scrollbars=no, top=0,toolbar=no,location=no,menubar=no ');");

Dear All,
I am in a need to read .aspx and .config files from a remote system. For that i have used the following method.
public string DownloadFile(string downloadUrl)<br />
{<br />
HttpWebRequest req = (HttpWebRequest)WebRequest.Create(downloadUrl);<br />
req.Method = "GET";<br />
HttpWebResponse resp = (HttpWebResponse) req.GetResponse();<br />
Stream respStream = resp.GetResponseStream();<br />
StreamReader rdr = new StreamReader(respStream);<br />
string inLine = rdr.ReadLine();<br />
string strResult=string.Empty;<br />
while (inLine != null)<br />
{<br />
inLine = rdr.ReadLine();<br />
strResult +=inLine;<br />
}<br />
rdr.Close();<br />
return strResult;<br />
}
In the above code if i provide URI of a text fiel in a remot system the method reads the file and returns me the content. But the same is not working if i provide URI of a .aspx file. Can any body help me
ThanS in advance

I ran your code from a console application and it seems to work fine for aspx files. I've pasted below my test app based on your code. I requested several different aspx files on my localhost and one from a public url and all were succussful. Can you reach the pages using your web browser?
Also, if you are trying to read .config files you will run into a problem there as ASP.NET will deny all requests for config files. There is a possible way around it, but it would be a big mistake as it would open up a huge security hole giving the public access to your connection strings and other sensitive config info.
using System;
using System.Collections.Generic;
using System.Text;
using System.Net;
using System.IO;
namespace ConsoleApplication1
{
class Program
{
static void Main(string[] args)
{
string input = string.Empty;
while (0 != string.Compare(input, "exit", true))
{
if (!string.IsNullOrEmpty(input))
{
Console.WriteLine(DownloadFile(input));
}
Console.Write("\r\nUrl: ");
input = Console.ReadLine();
}
}
public static string DownloadFile(string downloadUrl)
{
HttpWebRequest req = (HttpWebRequest)WebRequest.Create(downloadUrl);
req.Method = "GET";
HttpWebResponse resp = (HttpWebResponse)req.GetResponse();
Stream respStream = resp.GetResponseStream();
StreamReader rdr = new StreamReader(respStream);
string inLine = rdr.ReadLine();
string strResult = string.Empty;
while (inLine != null)
{
inLine = rdr.ReadLine();
strResult += inLine;
}
rdr.Close();
return strResult;
}
}
}

Thanks Mark ,
Well it is working fine for me too. But the exception is that it only reads .aspx files of an application if i copy an .aspx file from a web application and store it in a folder, which is set with web sharing for every one, then it fails to read the content. It will be very help ful for me if you let me the work around to be followed to read .config file.
ThanS in advance.;)

Not sure what you mean here. Are you trying to read the source of the aspx files? Or just the output? And are you requesting the files from an HTTP server (IIS) or trying to use file sharing? If you're trying to use HttpWebRequest to get the source of the files from a windows share you're using the wrong methods. If this is the case then you need to be using FileStream objects, not request or response objects. When you request files from a share over a network you don't use a web browser, you use windows explorer. Using the WebRequest objects is the equivelent of using your web browser. If you want the equivelent of windows explorer you use the FileStream objects. Also, this means you won't need to open up a security hole in your web application by exposing your config files publicly.

the default setting for .config files is in the httpHanlders section. It's defined as follows:
<add verb="*" path="*.config" type="System.Web.HttpForbiddenHandler"/>
In order to provide public access you'll need to change the handler for config files. I've never tried it, so I'm not positive which one. But my first guess would be System.Web.StaticFileHandler. If not you may have to roll your own handler which opens the files and spits out the contents to the response steam.
But as a disclaimer, I want to say exposing your config files like this is a really bad idea. If you need programmatic access to the content of remote config files I would suggest using FTP instead. .Net doesn't have any built-in FTP libraries, but I've seen some free ones out on the web.

In your btnSave_Click event you can call an update command for each record w/in the loop. Based on which checkbox is selected, call the appropriate update method (INSERT/UPDATE/DELETE).
The other option is to perform each operation (Add, Update, Delete) on a DataTable object, define a DataAdapter object and set the UpdateCommand, InsertCommand and DeleteCommand properties then pass the DataTable to the DataAdapter.Update() method.

Use Javascript to handle the onclick event. You should have no difficulty finding resources here [^]
only two letters away from being an asset

hi i m mayur
you can write javascript onchange event on bropdownlist
in javascript you can show hide panel or div
like
document.getElementById('rfvleavingdate').style.display = 'block';
document.getElementById('rfvleavingtype').style.display = 'none';

Hi, now i my ISP's smtp server and it is "maltanet.net". Now for some reason, from the localhost it is being sent fast and the email is being sent for REAL. but when i am uploading the website on the server, the email will be sent very long (very slow) and the email is not being send!  why is this?

Check the SMTP server of the server machine where you uploaded...

|
|
|

Thanks very much bro!! it worked 100% because the problem that i was doing, is that i was using the smtp of the web server on my localhost and it was firing back an error about spamming. then when i uploaded the asp files, they worked well with the smtp of the web server!!
Thanks again!!

Hi! Does anyone know how the following files encircled in red were added into the project?(see image from link)
http://img.photobucket.com/albums/v247/diorelle/cultures.jpg[^]
There isn't any template for it when I try to add a new item into the solution, plus the item doesn't go under the Global.asax file... I wanted to add a new resource file for another language...
Thanks so much! 
|
|
|
|
|
You can add the language-specific resource file as you would with a normal file, then you need to open the project file and add the DependentUpon attribute for the File entry of this resource file. You can see the File entry of the Global.asax.resx in the project file as an example.

I have a page that uses javascript to encypt its contents after a button is pressed before calling
document.forms[0].submit();
to submit the form, however the event handler for the button is not called.
I dont want to call it from postback as there are other server control on the page - any ideas what could be goind wrong?
I have already tried repairing "ASP.NET" as some times I know this can happen but I have had no luck.
Any help will be apreciated.

The problem is that when you just call submit() on the form instead of using postback the post is missing the arguments needed to call the proper event handler.
Could you clarify what your requirements are? Why don't you want to call postback? It sounds like you want to make sure all the data on the form is submitted, but this is what happens by default. After the client-side postback methods are called the form.submit() method is called if there are no errors.
|

|

Hi
Sorry for not being clear. I do want postback to be called, however at the moment I explicitly call btnSubmit_Click in my postback so that it would fire the event.
I feel this is becoming more of a javascript issue now and that this is the wrong place for it but how do I make it so that it just postsback rather than use submit()
Sorry for the wrong message board.
Cheers
Dan
