Send Already Established Authorization With New HTTPWebRequest?
Jul 20, 2011
I have a Asp.net Web Project using authentication mode="Forms". My login works perfectly. Now the Problem is that I have a link in a site that is only available to authorized users. It is possible that the pdf file of that link does not exist. What I want to do is to verify the availability of the pdf with a HttpWebRequest. Since the pdf file is only available for authorized users (web.config/location/system.web/authorization) I have to mark the HttpWebRequest as authrorized. But I don't have the logincredentials at this time (only when the user logs in and the .net framework wouldn't get me the password of the user). How to send the already established authorization with a new HttpWebRequest?

This is the short instruction:
1) Make a single HTTP-POST request to the following URL in XML format.
[URL]={password}&user={username}
2) The xml form field that is posted should be named "createorder".
I don't get the last part with naming the xml form field. What the xml form field means (stands for) in this context?

I am making changes to my companies internal paysite in order to come into compliance with the new credit card regulations. We have decided that when we get a split tender transaction that comes through we want to get the remaining balance along with how much was on the card to start out with and send that info back to the customer service rep with a message relaying the need for another payment source along with the remaining balance and the amount that was originally on the card.
Instead of chaining the transactions together with the split tender Id we have decided we would like to finalize each split tender transaction with a prior_auth_capture and then request the next payment source and amount and process that transaction in the same manner. I know that we are side stepping the functionality some but those are my orders.
My questions are, is this feasible and possible and how do you do this in code? I am using the C# SDK to implement this in VB.NET 2008
My thoughts are that I would have to process the transaction for the amount passed as a auth_capture transaction and then some how do the prior_auth_transaction with a zero amount or something?

I need to validate a basic authorization header that is being sent to my HttpListener in VB.NET. I'm grabbing the header like so (feel free to point out better ways to do this as well):
EncodedAuth = Context.Request.Headers.GetValues("Authorization")(1)
Now how do I decode them? I understand the theory but I can't seem to find the right code.

I made this login script and I want a user to download a file when they login. The download file button checks a folder named login. Once a user logs in it creates a folder named login then it allows the user to download the file. The only problem I have is that I don't know how to let the download button accept any user. Right now the person has to be named chris and they can choose what password they want. Also how do I allow the program to place the file on the desktop and not the test folder. I didn't know the code for it because each user has a

And move them outside of the web.config or something simlar? I find these nodes at an extreme amount of noise to a web.config when they're relatively static. Normally my approach would be to config source something like this but since it falls under the root node I'm not sure of it's possible with these nodes.

i created the following ActionFilterAttribute to check if a user is granted access to a page. I also created two custom Exceptions to handle different scenarios: NotLoggedInException and InsufficientPrivilegeException.
[Code]...
Where do I catch the exceptions to for instance redirect users if not authorized?Should I perhaps use the SiteMap authorization somewhere else instead of using the ActionFilterAttribute and throwing Exceptions..?
note: as you can see I'm using a custom class for BLL.Page. This is a ORM page which has Role based security stored in the database. SiteMap is also populated based on this data

I am trying to make an oledb connection to an Access database.
1. I added a component class.It said drag from the toolbox to add components.
2. I dragged over the Oledbconnection and OledbdataAdapter
3. I clicked on new connection string for the oldeb Connection and try to connect to the SHX.mdb datababase in the debug/ bin folder I don't have a username or password for the database and do not want to set one up.( is this possible in .net?)
4.As soon as I try to test the connection, I get the "invalid authorization specification" message. I can't get past this and do not really understand why I am getting this message.I have vb 2005 standard edition, not express edition.The exact same thing happens when I try to set up the data adapter to the shx.mdb database.
I am on XP2 and not logged in with a password or username. Could this be the issue or is there something else I am overlooking.Also, since I am coming from vb6 and ADO is there anyway to just write the code without having to use datasets, adapters and oledb connections to bound controls?

Now as you can see it is sending the textbox1 text and then pressing enter then sending textbox2 text! Theres quite a few problems in that but before i discuss note: This code is in a Timer. Problem #1: It does not send the keys fully correct all the time because its trying to send them all at once! So i want it to send them 1 letter after the other with 200 ms sleep in them! Problem #2: The sleep is not working: The reason i know is because even after it did the first textbox1 text it didnt wait that 2000 ms!

I am trying to send keys to a control on my form. But I am getting a NullReferenceException and I don't know why. The code is about as basic as it gets: [Code] The error reported is object reference not set to an instance of an object but Send is a shared method so doesn't need an instance. Strangely if I ignore the error it works fine and F4 is passed to the control. I know there was an issue with sendkeys and UAC but I thought this had been solved (I am using 4.0 framework).

I have a filter that is used to populate a grid view and the url will conain: /example/grid?value1=1&value2=2
It will then have a link to page 2, which allows them to edit something.I then want them to click a link that will send them back to the gridview under the same parameters of: /example/grid?value1=1&value2=2
Is this possible? How do I hold on and fill in the URL values so it knows how to refill the grid view accordingly?

I am facing a strange problem with listbox. I need to scrab whois information. I used the following code to get source code of the whois query. It works fine if I use a textbox. But I need to use this for multiple url and therefore need to use lixtbox to loop through url list. Unfortunately when I use listbox1.selecteditem or listbox1.text it does not work. But this same code works with webbrowser.

I'm building this class to download files in parts/sections/segments. In .NET 4.0, I can use this code to specify the range to download from
long startPos = int.MaxValue+1;
HttpWebRequest.AddRange(startPos);
and it works because there is a long overload for the AddRange method. When I looked up the .NET 3.5 version, I realised the AddRange() method allows using int only. The possible workaround would be using the AddRange(string, int) or AddRange(string, int, int) methods. Since the class will have to work in .NET 3.5, I'll have to go with the string specification but unfortunately I can't seem to find any sample code that shows how to specify ranges using this procedure in .NET 3.5. Can anyone show be how to do this?As the first code sample I wrote shows, I would like to specify a range of type long instead of int. Using type int allows requesting for byte ranges only up to 2GB but long allows requesting for byte ranges beyong 2GB.
The question therefore is: How do I specify byte ranges of 2GB or higher on HttpWebRequest in .NET 3.5?

how to write a httpwebrequest, however i'm unsure of how to write it with a if...statement. I have a file that I need to download, however it ususally doesn't get posted until sometime Tuesday afternoon, so what I need to do is have the program continually check say once about every 5 minutes until the file has been posted and then download it.I'm presumming using an if...statement is the best way to accomplish this, basically if true(file exists) then proceed, else wait 5 minutes and rerun process.
