C# - Send Server.UrlEncoded XML In Querystring Causing Error?

Apr 23, 2010

I'm trying to send a string of XML as part of the query string. Normally I'd POST this XML but I'm sending it to a 3rd party system that I can't POST stuff to. So, as it goes, I need the 3rd party system to request the services of one of the pages in my system. (explanation: the 3rd party system produces PDFs of my web pages. I give it a URL to my page, and it PDF's that page. So, the XML file contains data that I need to generate the page) Anyway, I'm getting my query string as follows:

string data = Server.UrlEncode(xmlSnippet.ToString());
string sFullUrl = urlString + "?data=" + data;

I give the 3rd pary system this URL, and it calls my page.. except the request doesn't reach the page. It's failing into the Application_Error handler with this message:

"A potentially dangerous Request.QueryString value was detected from the client (data=[my XML data])" As I know the data I'm sending is safe, is there any way I can make this work?

SQL Server :: Connection To Database Expires Causing An Error?

Aug 9, 2010

I have an asp.net web page which works with a database. When I first upload it I never disposed the connections so after using the different modules of the application for sometime it would suddenly stop working saying the connection pool filled or something like that.To fix it when a user clicked a button I opened the connection, tell the database what I needed and finally disposed the connection.

This seemed to fix everything, in fact you can work with application all you want, the problem comes if you stop using it for certain time.So for instance, I have a module in my webpage where user can capture information for a certain product. When the user clicks in one button the info gets into the database. If the user is continuosly capturing data everything works fine, but if it goes for about 10 min when he clicks the button he will receive an error. To fix this the user has to log-in again.

Every module opens a connection to the database to verify the user identity, but then after it verifies it I dispose the connection so I don't think there is a problem.

AJAX :: Greater Than Symbol Causing Internal Server Error 500?

Feb 8, 2011

If a user enters "<" or if it already exists in a textbox inside an update panel, I am getting "internal server error 500" during post back. I believe the page suspects a HTML injection and is attempting to stop it. I could use Page.EnableEventValidation to avoid it but I really don't want to do that. Is there any other way, I could resolve it (like replace < with > or something like that)?

Update:

This is happening in a textbox inside a gridView.

Configuration :: Error Handling - Crendentials To Send Email When Server Error Occurs?

Nov 14, 2010

When a server error occurs for whatever reasons (YSOD), the server will send a message via SMTP class. In my case, my company employs microsoft exchange and uses NTLM authentication for all domain users. I am authenticating users via NTLA windows integrated authentication. My question is, is it possible to utilize this authentication data, and pass it to the system.web SMTP username/password authentication scheme to send an email to me (the web developer) when the error occurs? I am pretty sure my company requires a username/pwd to send emails via SMPT on the ms exchange server.

Data Controls :: Populate DataList Based On QueryString Value Throws Error When QueryString Is NULL Or Blank

May 7, 2015

The following code works well as long as I pass a querystring value to the datalist.

Private Sub BindGrid()
Dim id As Integer = Integer.Parse(Context.Request.QueryString("id"))
Dim strConnString As String = ConfigurationManager.ConnectionStrings("Conn").ConnectionString
Using con As New SqlConnection(strConnString)
Using cmd As New SqlCommand()
cmd.CommandText = "select Id, Name from tblFiles where Id=@Id"

[Code] ......

However, the page errors with the message "Value cannot be null." if I don't pass a value. I know that DataList does not have an EmptyItem Property like a Gridview control. I do not want the page to error if I don't pass a value. Need info to deal with empty values in a datalist.

Most websites have pointed me to this code to use:

<FooterTemplate>
<asp:Label ID="lblEmpty" Text="No Result" runat="server"
Visible='<%#boolean.parse(([b]list[/b].Items.Count=0).ToString())%>'>
</asp:Label>
</FooterTemplate>

The 'list' throws an error. The error is "Too few type arguments to 'System.COllections.Generic.List". I am not sure if the code is written in C# and that is what is causing the error. It seems that it should work but I can not figure out the 'list' error.

HttpHandlers / Modules :: URL Rewriter Causing A "500 Internal Server Error"

Apr 1, 2011

I've set up URL Rewriting per Scott Guthrie's guidance (Scott's blog - Approach 3: Using an HTTP module to perform extension-less url rewriting with IIS7) and I'm using Url Rewriter.

OK, so it was a piece of cake to setup and everything runs perfectly on the dev server (cassini). I was all excited and put it on the production server and it immediately choked - the site won't even load and instead gives a "500 internal server error"

Production server is a shared hosting environment running IIS 7 in integrated mode , ASP.net 3.5 and SSL.

I have another HTTP module installed called Security Switch , which I disabled to remove it from the equation. I don't think that affects anything since it was already running fine on the dev server and prod server, but I'm not 100% sure and wanted to throw it out there if that helps diagnose.

I've followed the setup instructions precisely, triple checked everything in web.config and I can't figure out what I'm doing wrong. I'm guessing it must be getting stuck in the IIS 7 pipeline somewhere. Can the SSL have something to do with it?

Send Multiple Parameters Via Querystring Asp

Mar 5, 2010

Which is the best way (in performance and security) to send multiple parameters to a web page (on a different server), considering that the length of the parameters may vary because I'm sending a list of products, and the customer may have selected more than one product, so we need to send each product on the querystring to the other page. For example (I'm on C#); I want to call a web page like this:

Simple Querystring: thepage.asp?Product=1&Name=Coffee&Value=1.99
Json: thepage.asp?{"Product":"1","Name":"Coffee","Value":"1.99"}
XML: thepage.aps?<xml><Products><product>1</product><name>Coffee</name><Value>1.99</Value></Products>

(Obviouly considering we can't send special characters via querystring, but I put them here for better understanding) Which will be the better way (performance, security)?

MasterPageFile Causing Error?

Aug 12, 2010

I'm trying to use a master page in my website. I created a page and then created the master. I then added the tag MasterPageFile="~/master". I'm guessing that I need to do something to my main page, because I've now started getting the error:

The page contains markup that is not valid when attached to a master page

My main page is as follows:

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" MasterPageFile="~/my.master" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<body>
<form id="form1" runat="server">
<div>
</div>
</form>
</body>
</html>

I tried deleting the tag thinking that this might be the issue. Can anyone point me in the right direction?

Can't Send Smtp Email From Network Using C# Error / Unable To Connect To The Remote Server

Apr 1, 2010

I have my code here, it works fine from my home, where my user is administrator, and I am connected to internet via a cable network.

But, problem is when I try this code from my work place, it does not work. Shows error:

"unable to connect to the remote server"

From a different machine in the same network:

"A socket operation was attempted to an unreachable network 209.xxx.xx.52:25"

I checked with our network admin, and he assured me that all the mail ports are open [25,110, and other ports for gmail].

Then, I logged in with administrative privilege, there was a little improvement, it did not show any error, but the actual email was never received.

note that, the code was tested from development environment, visual studio 2005 and 2008.

try
{
MailMessage mail_message = new MailMessage("xxxxx@y7mail.com", txtToEmail.Text, txtSubject.Text, txtBody.Text);
SmtpClient mail_client = new SmtpClient("SMTP.y7mail.com");

Event Causing Error But Can't Catch Exception

Apr 22, 2010

A developer has created a custom control in ASP.NET using VB.NET. The custom control uses a repeater. In certain scenarios, the rpt_ItemDataBound event is encountering a data error. My goal is rather than having the user see the yellow screen of death, give the user a friendlier error explaining exactly what the data error is. I figured I would be able to use a Try/Catch block as shown below throw the exception, however, it appears that the event has nowhere to be thrown to and stops executing at the "End Try" line.

Protected Sub rpt_ItemDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.RepeaterItemEventArgs) Handles rpt1.ItemDataBound, rpt2.ItemDataBound
Try
ProcessBadData...
Catch ex As Exception
Throw ex
End Try
End Sub

In VB.NET, I can find where the repeater's DataSource is being set, however, I can not find a DataBind event. how I can capture the exception in this ASCX control so I can report it to the user? Edit: The stack trace looks like this. There is another repeater within the repeater that is actually causing the error (rptOther) and I'm able to catch the error, but I can only throw it to the rpt_ItemDataBound. I can't figure out how rpt_ItemDataBound is getting called without a DataBind event.

at Company.WebForms.Control.rptOther_ItemDataBound(Object sender, RepeaterItemEventArgs e)
at System.Web.UI.WebControls.Repeater.OnItemDataBound(RepeaterItemEventArgs e)
at System.Web.UI.WebControls.Repeater.CreateItem(Int32 itemIndex, ListItemType itemType, Boolean dataBind, Object dataItem)
