Enable Reverse DNS Lookup For IIS?

Feb 24, 2010

(Not sure if I'm creating this post in the right place. Feel free to move if needed.)

I'm trying to enable full DNS lookup including hostname. Having trouble. I've followed the instructions here

(http://support.microsoft.com/kb/297795) with no luck. Request.ServerVariables("remote_host") still returns only an IP Address.

[Code]....

I've also tried using DNS.GetHostEntry(IPAddress) and the depricated DNS.GetHostByAddress(IPAddress). All I ever get back is the IP Address with no host name.

IIS 6.0, Windows Server 2007 Server Pack 2, .NET 2.0

C# - Reverse Engineering .net Web App?

Feb 16, 2011

I have an asp.net web application. I don't have the source code. The bin contains 10 assemblies and a .compiled file. I used Reflector on the App_Code.dll and it shows me classes and namespaces and stuff, but its such a mess.Is there any way to reverse engineer this web app that won't take weeks/months to unfold? The application is pretty basic.

Note, the code is written by an engineer that left the company. We own the product.

MVC :: Reverse Proxy And Authentication?

Feb 21, 2011

We have nearly completed an ASP.NET MVC web application running with SSL in IIS and now find that we must integrate with a third-party product that is supplied as a PHP web app running under lightppd on an alternate port, but still on the same server.

We want to make the integration appear as seamless as possible, so our initial strategy is to do all of the authentication through our application, implement a reverse proxy to expose selected features from the third-party product, and then set-up the third-party product to only be accessible from localhost and (if we can manage it) only from the user our app pool runs as. As a second layer on top of this, we plan on running the third party active content in an IFRAME, so we can surround it with our menus and headers. With the right fonts and colors, hopefully, it won't look grossly out of place.

First question: Is this strategy totally naive? Given the hand we've been dealt, is there a better one?

Second question: What is the best way to implement the reverse proxy? I was thinking of using a routing rule with an Http Handler that invokes our usual authorization just as a controller would and makes the requests to the other site, streaming out the results it receives. Is there something that already does this generically, that I can just hook up and invoke? Maybe some way to specify a controller to handle everything I need to proxy and then use a ViewResult that represents a call to an external URL I construct from the URL I received?

If I can get a few pointers on what to look for, I can trot off to the docs for the details.

Do The Reverse Of A Regular PayPal Transaction?

Jan 4, 2010

How can I do the reverse of a regular PayPal transaction. The only information I found in their documents was for the customer to pay us for things. What if we want to pay out the customer?

Is there a way to give a transaction type to reverse and pay out to the customer instead of them paying us?

Update: Turns out you can use Mass Payments to pay out to customers... just needed to look on StackOverflow a bit more [URL]

AJAX :: WebResource Fail To Work Under Reverse Proxy?

Jul 19, 2010

We have an issue when our web application runs under reverse proxy.

The reverse proxy change the URL for the website from for example: "http://TestWebApp/" to: "http://ProxyDomain/Test/" when it runs under reverse proxy which is mapped to "http://TestWebApp/" and rout requests to it.

This raise an issue of root relative paths (paths that start with "/" to be relative to the root of the web application i.e. "/Folder1/Test.aspx"). Generally all paths that need to be rendered to client we use ResolveClientUrl method and all is good.

When using Ajax controls and ScriptManager WebResource.axd paths are rendered in script tags as a relative url paths ("/WebResource.axd?blablabla") because the root under reverse proxy is the proxy domain itself the path is useless - the web resouce is not downloaded and the application break.

To fix this we tried to set a Response.Filter in OnPreRender event handler of our base page. In our custom filter we use Regex to search and replace all "/WebResource.axd" occurences with the resolved to client root path using the ResolveClientUrl method of the page. This works great and the web resources are downloaded to client.

But this is not the end of our troubles.

In Ajax requests the response output is fixed as described but when recieved at the client end it is not valid and the partial update fails with Sys.WebForms.PageRequestManagerParserErrorException.

It fails to parse the response because the rendered response have numbers that states the actual count of bytes per rendered component (which includes the script tags referencing the WebResource.axd). The client reciever validates the recieved response according to the numbers, but, our filter altered the response so the numbers are not correct and the response validation fails.

We can try and code a smart filter that parse the response and recalculate the numbers according to the ammount of paths fixed, but I hope there is an elegant and better solution for this.

How To Add Code / To Use LtlBranch As My Lookup Variable?

May 19, 2010

I have a site which I need to modify and add phone numbers based on what branch is being displayed. I have NO clue what-so-ever on how to do this.I have a .aspx file which is using another file as its code behind. My first question is: If I want to add "if statements" into this code, do I add them in the .aspx file or the code behind (aspx.vb) file? Next question is: A statement like
"<asp:Literal runat="server" ID="ltlBranch" /> Employees"

is using ltlBranch to place the branch name in front of Employees. Can I use ltlBranch as my lookup variable? In other words, is this valid coding for asp?


If ltlBranch="MainStreet"
show the rest of my code[code]...

Should I be creating a sub-routine within the codebehind form and then calling that routine? I am clueless on how to go about this, and am just trying to get a starting point so I can look up more info on it.

AJAX :: Modal Lookup With Gridview?

Jan 27, 2011

I am creating an application and requiring users to enter an Employee id number. I do not want them to freely enter the number so I have a text field with a Find button connected to a ModalPopup Extender.
The modal panel appears with fields for first and last name along with a Search button.

I want the users to be able to search for an employee and have the results returned in a gridview within the modalpopup. When the user clicks the select link in the gridview next to the employee that choose, the modalpopup should close and send that value back to the text field in the main form.

The problem I am having is when I click Search the gridview does not appear.

I can bind the gridview at the page load but then the grid appears with all the listings.

C# - .NET Exception Handling Lookup From A Table?

Mar 25, 2011

My manager designed a table exactly like this

[Exception]
PK | ExceptionId
ExceptionCode varchar(100)
ExceptionDesc varchar(255)
ExceptionMSG varchar(255)

I'm using ASP.NET Webforms and using stored procedures/ADO.NET for DataAccess. Now he does not want me to hard code validation in stored procedures nor in the code behind, but to catch the constraint exception message and look up the same error message in the database and look for the message that we want to show. I wonder if his design will work or should I explain to him that something is wrong here.

DataSource Controls :: Using Lookup Value In Gridview?

Sep 15, 2010

I've been struggling all day trying to make this work, but I'm just not having any luck. I have 2 tables, 1 is a lookup table and the other is a user table. The lookup table stores the State values in text form, where the user table stores the ID of the State for the particular user. I'm trying to create a editable grid view that allows the user to update their State based on values in the lookup table. I've created an Edit Template with a drop down for the State field. When the user clicks on "Edit" in the GridView I need to be able to reference the SelectedValue of the State and write the index of the State to my user profile table. I'm using two different data sources for this since the GridView needs to display each record from the users table and the Edit Template needs to display only values from the Lookup table. I've included my code below.

<%@ Page Language="C#" MasterPageFile="~/JFCS.Master" CodeBehind="modifyFunder.aspx.cs" Inherits="jfcsGRAMS.modifyFunder" %>

C# - Postcode And Radius Lookup Recommendations?

Apr 16, 2010

I look after a number of divisional websites for a uk based membership organisation and what we want to do is provide, as well as other address functions, is a closest member lookup to a web user from the websites themselves.A few use cases that I want to fill:ase 1: The user puts in their post code and wants to see all the members in a 5/10/15/20/30/40 mile radius from themCase 2: The member puts in an area (city, county, etc.) and gets a list of members in that area.Essentially what I'm looking for is a programmable API which I can code against to do:post code lookup and returns addresses (after picking house number for example).
search post code + radius (5miles, 10miles etc) and get a set of applicable post codes to then join onto the membership records in the databaseAny recommendations? It can be a quarterly update install on the server, it can be a queryable web service.
