I am facing a problem related to register routes.
private void RegisterRoutes(RouteCollection Routes) { Route myroute3 = new Route("{controller}", new MyRouteHandler()); Routes.Add(myroute3); }
Now, I intentionally made an error. asp.net not showing the appropriate error but "page not found" When I traced it: its is showing the following stack trace: [URL]
Source: System.Web Message: Error executing child request for Error.aspx. I am not been able to track errors.
I have a thread class which makes a web request. After 20-30 urls request, its throwing exception: System.Web.HttpException: Request timed out. My code is below where it is throwing exception:
httpReq.AllowAutoRedirect = false;
httpReq.KeepAlive = false;
httpReq.Headers.Add("Location", "");
httpReq.Timeout = this.HttpRequestTimeout;
httpRes = (HttpWebResponse)httpReq.GetResponse();
In last line : httpRes = (HttpWebResponse)httpReq.GetResponse(); it is throwing exception. "The remote server returned an error: (403) Forbidden."

View 4 RepliesOn a webform, I've got a Button inside a Placeholder control. Initiallty, I set its Click event declaratively in markup:
<asp:Button runat="server" ID="btnSubmitAgain" OnClick="btnSubmitAgain_Click" CssClass="button iconButton SubmitAgainbtn" />
However, everytime I click this button it bypasses the defined handler (the breakpoint I set is never hit) and behaves like a generic submit button and causes a postback. My handler clears a session variable and then Redirects back to itself so does not cause a postback).I've got an almost identical version of this form which behaves correctly and is, to all intents and purposes, identical code.
I hav button on a page. click on it and it works on local system. when i deploy on server. code seems not working. I receive a 'request failed' and truest level error. method even contains 1 simple stmt of 'exit sub'. it's not happening on other pages.
View 3 RepliesI am using Itext sharp to create a pdf. I am adding an image and I keep getting this error
Request for the permission of type 'System.Security.Permissions.FileIOPermission, mscorlib, ersion=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.
it is this bit of code that is causing this
[Code]....
If i comment this out, the PDF builds and no errors are thrown (there is just no image)
I don't understand cause I am am trying to do is read a file.
Edit : Problem wasn't related Event Propagation, if you want to know how to stop propagation in jQuery, then use event.stopPropagation();
When user moves his/her mouse over <span> element my jQuery code appends an <img>into this <span> element and when he moves out his mouse off <span> than the element appended is removed. It helps people to edit the field when clicking on the appended <img> element.
The reason I used append() method to add <img> into <span> is because I want to keep <img> element visible when user moves his mouse over to appended <img> element (<img> is becoming <span>'s child element) But it didn't happen and when user moves his mouse over it <img> is being deleted. I am thinking it is because event propagation but I couldn't find how to activate it in jQuery as we do with addEventListener in Firefox based browsers.
JQuery Code :
$(document).ready(function() {
$('.EditEnabled').bind("mouseover", ShowEditFields);
$(".EditEnabled").bind("mouseout", HideEditFields);
});
function ShowEditFields(event) {
$(event.target).append(" <img id='editImg' src='images/edit.png' style='margin-bottom:-3px'/>");
}
function HideEditFields(event) {
$(event.target).children("#editImg").remove();
}
Simple HTML :
<span id="something" class="EditEnabled">Something Here</span>
I have a control that handles commenting. In this control, I have set a delegate event handler for sending an email.
I then have various types of controls, e.g. blog, articles etc, each of which may or may not have the commenting control added (which is done dynamically with me not knowing the id's), i.e. the commenting control is added outside this control. Each of these controls handles it's emailing differently(hence the event).
What I'm trying to determine, is how to assign the event in the parent control. At the moment, I'm having to recursively search through all the controls on the page until I find the comment control, and set it that way. Example below explains:
COMMENTING CONTROL
public delegate void Commenting_OnSendEmail();
public partial class Commenting : UserControl
{
public Commenting_OnSendEmail OnComment_SendEmail();
private void Page_Load(object sender, EventArgs e)
{
if(OnComment_SendEmail != null)
{
OnComment_SendEmail();
}
}
}
PARENT CONTROL
public partial class Blog : UserControl
{
private void Page_Load(object sender, EventArgs e)
{
Commenting comControl = (Commenting)this.FindControl<Commenting>(this);
if(comControl != null)
{
comCtrol.OnComment_SendEmail += new Commenting_OnSendMail(Blog_Comment_OnSendEmail);
}
}
}
EDIT:
The reason I ask is that if I search from this.Page as the initial control, I am worried about time taken to search down the control tree to find it. Each different type of page would be different in how many control it would have. On some testing, it returns back quite quickly the result.

There are plenty other similar static methods defined within the class.
When does it fail: ONLY when the solution is compiled in 'DEBUG' mode. Everything works fine in 'RELEASE' mode.
What have I already tried:
1. Including a static constructor inside 'Utility' class - FAILED
2. Marking 'Utility' class with 'static' keyword: FAILED
3. Changing platform target from 'Any CPU' to 'x64': FAILED
As highlighted above, the issue is really not with VerifyPassword() method per se. Rather it is with the instantiation of 'Utility' type. That's why an exception is thrown from the constructor. Since 'VerifyPassword' is it is the first static method called, it appears in the stack. Just for the sake of proving that, I removed the call to VerifyPassword and returned 'true' instead. That way I was able to login to the application (no password verification), but failed at a later stage where I had called the Utility class on another method, namely Utility.ValidateSKUAdjustment(txtCurentMonthM1.Text).
I am working on a web application. Some images are calling a web provider, which renders the picture, and send it to the client (the html looks like img ... src="/WebProviders/ImageHandler.ashx?.../>).The problem I have encountered is that both IE8 and Firefox 3.6.8 fire the request to the handler more than once, yet not consistently. I could not trace a pattern (the same image sometimes cause one and sometimes several requests).
View 1 RepliesI have a webpage where I am displaying some data.
On the top of that I have a button. On click of this button I am calling my webhandler using jquery/json, passing in some data to this handler. Now this data can containg html tags. So whenever I try to click that button it gives that Potential threat script
error. So I thought let me include ValidateRequest = false to my webpage.
Now when i do this it never hits my handler. I tried to debug also but my breakpoint is never hit in my handler. How to handle this.
This is how I call my handler:
[Code]....
where hidden value is the value which I want to pass to my handler and may contain html tags..
Is it possible to call a handler using javascript code? e.g. i have a handler deployed at this location http://mysitename.com/getMyData.ashx. Can I call this handler or just request it using javascript?
View 3 RepliesI am trying to implement the Ajax HtmlEditor into my application. I currently am using a regular TextBox to load and save some data to some EMail template files and had to do some work-arounds to get it to accept the HTML Input. I am trying to upgrade it to use the Editor, but as soon as I insert the Editor and do a PostBack, I receive the Security Exception below. There is absolutely no change to the code-behind, so I don't understand the issue. There is so little on Google for the Version 3.5 Editor that I'm stumped. I have Debugging enabled, but it won't give me the Soruce Error either.

"fileUpload" is the FileUpload ASP.NET control. The SaveAs method writes the user uploaded file to a specified location on the server. IT WORKS. That tells me that the ASP.NET process has the proper write permission to write to the file.The next line uses an assembly called PdfSharp which you can use to open PDF files and manipulate them. In this case, the line simply opens up the user uploaded file. That is where the error occurs. WTH?
It works on my production machine. It does not work on my local machine. It USED TO. It was never a problem before.So why would it be fine to WRITE to the server, but trying to open a file give an error? Makes no sense. Googling yields a suggestion to put <trust level="Full" originUrl="" /> under <system.web> in web.config. It does not work.
in my web project i got an error that i couldnt find any solution. the error says: System.Security.SecurityException: Request for the permission of type 'System.Data.SqlClient.SqlClientPermission, System.Data, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed. when i work in local there were no problem i put files to our server and i changed the database also. when i work in server in web application in Default.aspx i can connect db and get values without any problem using my DataLibrary
BUT the problem in my web service i also use my DataLibrary in webservice but when i try to run a method in web service it gives me the error which is : System.Security.SecurityException: Request for the permission of type 'System.Data.SqlClient.SqlClientPermission, System.Data, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.
my new db connection is
strConnectionString = "Data Source=OURSERVERNAME\SQLEXPRESS;Initial Catalog=DoveTR;Persist Security Info=True;User ID=sa;Password=123456789;Pooling=True";
I have a new virtual server, subsite. but I get the feeling I may be still be inherting from the root config! Even though I have included <clear/> within both the <connectionString> and <httpModules>.
The main website works (web1) along with one of the subsites (web2) however the 3rd subsite (web3) gives the below error.
e.g.
http://web1

Hopefully I am just overlooking something incredibly simple, if so I apologize....I have an ASP.NET application in .NET4 and we're trying to use URL rewriting using
<configuration>
<system.webServer>
<rewrite>
<rules>
<rule....>
For some reason intellisense is returning an error which says that <rewrite> is not a valid child element of <system.webserver>When I build it and run it, it says something akin to "Error at line 0 in web.config"If I remove all the <rewrite> lines it works properly (but of course no rewriting)Is there a switch I need to flip on or something? It has to be something I'm stupidly overlooking....
I'm trying to fix conical format violation for SEO but when I add <rewrite> to the <system.webServer> sectionI get this error the element system.webServer has invalid child element rewrite I've tried this by adding a rule withhe admin tool in IIS 7 and I've tried adding it directly into the web.config file in a 3.5 and 4.0 frameworksand I also tried it with VS 2010 pro and VS 2008 pro I can't find where I missed a step all the blogs and tutorials just show how to add this to the web.config file I haven't been able to find out how to add this element to system.webServer
View 3 Repliesam duplicating a site from a prexisting site.

This is quite perplexing as it i not doing this in the website i duplicated from.

it looks at Header, i dont think it can find the definition in this second website so it is returning System.WEB.UI.EmptyControlCollection. In the first website it is returning System.Web.UI.ControlCollection. Also when I go to the definition for Header, it opens up the Metadata definition in the first website. In the Second, it says "Cannot navigate to definition".
currently, I am working on the project where I have to configure Application on IIS7 with network drive and doing this I am getting the error regarding security. Let me explain in detail. We have two production server, both having Windows 2008. now one server acting as the storage server and other server will work as web server which having the IIS (here IIS7). Now, I have to deploy the application on the storage server and in web server I have to configure the application in IIS with the path of network drive (here network drive means path of the folder at storage server). At here I had provide the full path like \ servernamedrivename$foldername, and also provide the credential at "connect at" button.Now when I open the page it will display the page but with the following error.
Request for the permission of type 'System.Data.SqlClient.SqlClientPermission, System.Data, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed. Now new question that Credential is proper or not? Here my both production server having the user : username1 and password: Password1 but the domain is different. So, what I do that enter only the username1 in user name and password1 in password box.
