How To Hack DropDownList Value

Feb 28, 2010

I've got a DropDownList and I'm trying to prevent it from being used as an attack vector. Can I assume that the user is unable to actually change the values of the DDL and postback to the server? At the moment, I get this ASP.NET error message thrown if I try and change the packet after submission:For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them.Am I right in thinking that this is due to the integrity being compromised in the viewstate hash?

Finding Alternatives To The Often Broken App_offline.htm Hack?

Mar 14, 2011

In quite some scenario's, placing app_offline.htm in the root is just right: you do some updates, the message appears while updating, and that's that. The idea is, as Microsoft puts it, that before anything is called, IIS first checks if app_offline.htm is there and if so, it cancels everything and displays it.

So for so good, but in many situations it doesn't work:

When you have a compile error in an ASPX page and a user links directly to it When you have conflicting assemblies When you have a parsing error in your web.config In the midst of removing / uploading the entire site.

A direct link to a static HTML page is still displayed as suchm File-not-founds, access-denieds are thrown before the message is shown Possibly more scenario's exist that fail. My point is: for any serious updating work, app_offline.htm is not suitable. I sometimes create a redirect in IIS, to another site, but another site may not always be available and it can confuse users.

Ideally, I'd want to keep the current location in the url location bar of the end-user, show the message, and have the page auto-refresh each minute to see whether the site is back, so that the user continues where he left of when the site comes back. While technically easy enough with a static page, it will fail for the above mentioned reasons the minute an error is thrown.

How To Upload New Site And Keep Old Work

Aug 10, 2010

im new to asp.net, i have a dating software and it uses vwd2008, currently the software installed was the wrong 1, now i need to reinstall the new with chat.

I was told by the supplier that i can overwrite the existing files with the new package that has the chat. They say make sure to preserve files that i have made changes too and also run the ajax chat sql script from the sql folder.

My concerns are, i have a client base built already and i have made many changes, so i dont want to loose this.

How would i preserve them? If i drop and drag the folder will it warn me and give a option not to overwrite the files as it loads?

How do i run the ajaxchat script in my sql folder?

Upload File To Aspx Site With WebClient?

Apr 1, 2011

I have an aspx website and I'd like to upload a file to it. The file is being processed later, so I need to support some extra information with it.

This is the website I have to far:

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Upload.aspx.cs" Inherits="ABC.Web.Upload" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
</head>
<body>
<form id="Form1" method="post" enctype="multipart/form-data" runat="server">
<input type="file" id="File1" name="File1" runat="server" />
<input type="text" id="FileId" name="FileId" runat="server" />
<input type="submit" id="Submit1" value="Upload" runat="server" />
</form>
</body>
</html>

This (and the code behind) works very well when using a browser and clicking through the form. But I want to upload the file using the WebClient from C# code. I don't have to use the WebClient. I can also modify the upload.aspx to suit me, there is no requirement that it works from a browser, but this is the only example I've got working.

Looking at fiddler (I just started using it, so I probably have missed it) I could not figure out how I would create such a request from code.

At the moment when using the WebClient I am specifying the address and the local filename. I have a breakpoint in the code behind in my website but the File1 and FileId are not set (as expected).

How do I have to modify the website and how do I have to use the WebClient to get the upload working?

EDIT: Just found out about the Request.Files, that will give me the file, but how about the other fields?

Why Does Site Behave Differently And Starts To Refresh On Postbacks Once Upload It

Aug 17, 2010

I have a button in a repeater control. It saves the data on the screen, so ideally I'd like to do this and not have the screen refresh, as there is no new data to be shown. When I am debugging using localhost, the page just sits there, the data gets saved all is well.However, when I upload the very same page and code to my host, clicking the button causes a full refresh, which as there is a lot of data, means a long wait each time.

Web Forms :: Error Custom Control Mode When Upload Site On Server

Oct 22, 2010

i have uploaded my site [URL] it it working properly on local machine but when i uploaded on server i am facing 1 error on button clik of any form. there are two ages career and contact whenever i submit this data by clicking button i get this error. Server Error in '/' Application. Runtime Error Description: An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine.

Details: To enable the details of this specific error message to be viewable on remote machines, please create a <customErrors> tag within a "web.config" configuration file located in the root directory of the current web application. This <customErrors> tag should then have its "mode" attribute set to "Off".

[Code]....

Notes: The current error page you are seeing can be replaced by a custom error page by modifying the "defaultRedirect" attribute of the application's <customErrors> configuration tag to point to a custom error page URL.

Configuration :: Maximum Request Length Exceeded - Upload 13 MB Video File To Site

Feb 5, 2010

I am using DotNetNuke and I have posted this in their forum. But it is more appropriate here. I am trying to upload a 13 MB video file to my site ( a .flv file) using the file manager function under the host login. I understand that .NET limits the upload size to 4 MB for security reasons. In accordance with other posts here I added this code to my web.config file to allow bigger upload.

<httpRuntime maxRequestLength="51200" enable = "True"

I added it in the system.web section. Now, I still get this error:

"An error has occurred.DotNetNuke.Services.Exceptions.PageLoadException: Maximum request length exceeded. ---> System.Web.HttpException: Maximum request length exceeded. at System.Web.HttpRequest.GetEntireRawContent() at System.Web.HttpRequest.GetMultipartContent() at System.Web.HttpRequest.FillInFormCollection() at System.Web.HttpRequest.get_Form() at System.Web.HttpRequest.get_HasForm() at System.Web.UI.Page.GetCollectionBasedOnMethod(Boolean dontReturnNull) at System.Web.UI.Page.DeterminePostBackMode() at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint,

Security :: Transfer User From One Web Site Site To Another Web Site On A Different Server With User?

Jan 26, 2011

I have a requirement where I have to transfer a user from Web Site 1 on Server A to web Site 2 on Server B.

On Web Site 1, I have to provide controls to enter user id and password and which have to be validated on Web Site 2 on server B, after validating them I have to redirect the user to Web site 2.

what is best way fo doing it. code examples are greatly appreciated.

Note: On Web Site 2, user login functionality is already existing and it is provided by ASP.Net login control, am not sure how to handle the user login process from two different places.

or is it the best way to move Web Site 2 from Server B to Server A so that, the same login controls will be shown using Iframe on Web Site A.
