Jan 22, 2011I heard that .NET framework will encrypt the ViewState using SHA1 or some other algorithm. So if i know the SHA1 encryption and decryption algorithm can i tamper a ViewState?I mean a malicious user studies SHA1 encryption algorithm,if he understand that algorith and develops decryption algorithm ,will it open the road of viewstate tampering? or SHA1 or other algorithm uses any random tricks for encryption and decryption?

Architecture :: Naming Conventions&meaning Of Tables Is Not Clear On SQL Server?
Feb 2, 2011I have been using Sql Server since 2003, and still encouter situations that are just hard to solve :)I know it's a an sql server question, but since it's from a methodology and architecture point of vue, I thought it fit in this forum I am facing a sort of conflict with my current customer :An old sql server database, migrated from sql server 2000 to sql server 2008 (2003 project), which serves an asp.net application and cubes.naming of tables are like the following : tbl_ and Vw and yet procedures have no underscores. The database contains no functions.All object names are abbreviated, without any dictionary to understand what they mean. We have to ask every time.We developed a new module, and followed Pascal Casing, with clear words for the tables meaning.The customer makes a code review and says, that object are not correctly named :) and the meaning of tables is not clear. Names like AnalyticsAxis, is simply not clear. We also are asked to follow tbl.

State Management :: ViewState - Does The Master Page Have Its Viewstate
Apr 30, 2010I have been getting this error a lot lately with some of my users, and I had a couple of concerns with view state and I have read so many articles but I am still lost..
1. I use masterpage on all the pages and I need viewstate for some of the pages but..
There is a page where a user will fill out the information and then submit this data to a cgi server, and it is where I get most of the Client Disconnected errors, what would happen if I disable viewstate when they click on that button?
Now when a user browses from one page to another, does the view state from the previous page get deleted? If not how would I delete it?
Does the master page have its own viewstate? Would I be able to make sure none of items on my master page are using the viewstate?
C# - Page With ViewState Disabled Still Be Validating A Viewstate Field?
Sep 24, 2010I have a shopping cart page (Cart.aspx) that has a button that will (sometimes) post to a third party payment gateway, if payment is necessary. The payment gateway will process the payment and then do a silent post to my website (Order.aspx) so I can update the order status.
Order.aspx always throws an invalid viewstate error, even though viewstate is disabled on the page.
What's happening is that Cart.aspx (which has viewstate enabled) posts to the payment gateway, and the gateway will post it back as part of the silent post. Even though Order.aspx has viewstate disabled and validation disabled, it still tries to validate the __viewstate field it's being given.
I know setting EnableViewState=false will disable the rendering of the __viewstate field, but if another page provides the field, shouldn't it still skip validation? I tried calling ViewState.Clear() on the Page_Init event of Order.aspx, but ViewState is apparently empty. how to get around this? I don't want to disable ViewState on Cart.aspx (in some cases it may be necessary), but I can't figure out how to clear it on Order.aspx.
Trying To Interpret The Meaning Of "mscorwks.dll!StrongNameErrorInfo+0x7688"?
Apr 11, 2010I am trying to interpret the meaning of "mscorwks.dll!StrongNameErrorInfo+0x7688". I guess it means, that the assembly loaded by the mscorworks.dll has no StrongName? If yes, does this have any negative impact for a web application?
Is it safe to assume that the thread count of 107 means, that web application needed at a peek a maximum of 107 concurrent threads to handle incoming requests?

View 3 RepliesWeb Forms :: CreateUserWizard Encoding?
Jan 18, 2010 Can someone lead me to understanding when to set the encoding for the email step when sending new member emails. For instance what is the default or how can I tell what it is or if I want to set it in the SendMail event in code. See the thing I am wondering is when is it applied? If I set the MailDefinition-From in the html part then in code using the SendMail event set the encoding using
e.Message.From = new
MailAddress("foo@bar.com","foo",System.Text.Encoding.UTF8);
then I assume that it must actually get applied when the email is sent. Is that correct?
C# - Encoding While Parsing XML File
Dec 11, 2010I'm developing a small ASP.NET Mvc project in Mono 2.4, Ubuntu 10.10. There is an array of objects, each one of them corresponds to a certain xml file. Reading of the xmls is performed with XmlTextReader. That does not work because xml files have rare "cp866nav" encoding, which is not supported by XmlTextReader ("System.ArgumentException: Encoding name 'cp866nav' not supported"). But it works fine if encoding in xml header is changed to "cp866". I found a kind of solution which consists in initializing XmlTextReader with a StreamReader with a certain encoding instead of file name, like in the code below:
XmlTextReader reader = new XmlTextReader(new StreamReader(Server.MapPath(filename), Encoding.GetEncoding("cp866")));
The issue is that the directory which contains xml files is read only (I can not change it), so I get "System.UnauthorizedAccessException: Access to the path '' is denied.". Rather strange, because XmlTextReader initialized with a filename seems to read the files. Is there any solution, considering that program cannot modify or create files?

May 6, 2010I have a problem in my asp.net 3.5 application (C#) when I try to render in my pages characters like 'è' which are shown in a very strange manner (if i'm lucky i get a ? mark in my web page). in fact Expression Web, when i open my web site, substitutes the è char with �...How can I tell asp.net that I want to use a particular charset so that i can write in the html source letters like è without using hexadecimal codes??????I tried in the web.config this:inside the system.web namespace of the file but nothing works...
View 1 RepliesVB.Net MailMessage Text Encoding?
Mar 8, 2010I have an ASP.Net app that allows a user to write text into a Telerik RadEditor control and then send an email.
For some reason I'm sometimes getting strange characters showing up in the email that is generated.
For example if I put the word Test's into the RadEditor box and send it... the email shows up with the text changed to: Test’s.
It seems as though the ' character was used in place of ' because if I use the later, the text would show up just fine. If I pull up the saved record within the ASP.Net apps interface it looks just fine. It also appears just fine when I view the text within the recorded of the MS SQL table it was stored in.
I'm using MailMessage to create the email. I've check the string being sent at the point just before I use SmtpClient to send the message and it looks just fine at his point. Once the email message shows up however I get the strange text (Test’s).
I'm guessing that I have an encode/decoding issue but I'm not sure how I would go about fixing this.
Continued--->
I have tried to add it to the constructor of my email class with/without mybase but that had no effect.
Public Sub New(ByVal EmailDate As DateTime, ByVal LogoPath As String)
MyBase.New()
MyBase.BodyEncoding = Encoding.GetEncoding("iso-8859-1")
'BodyEncoding = Encoding.GetEncoding("iso-8859-1")
Me.EmailDate = EmailDate
Me.LogoPath = LogoPath
End Sub
I also tried adding it to the code behind of the form that calls the email class just before I create a new SmtpClient but that did not seem to be correct either.
Try
returnEmail.BodyEncoding = Encoding.GetEncoding("iso-8859-1")
Dim smtpCli As New SmtpClient
smtpCli.Send(returnEmail)
Catch ex As Exception
ScriptManager.RegisterStartupScript(Me, Me.GetType, "smtpError", "alert('There was an error sending the email:
* " & ex.Message & "');", True)
End Try
