Re: Password Field Padding with Question Marks (?s)

Converting a 30 byte binary value to characters will have the result you see. However, you do realise that any schoolboy hacker could get all your passwords with ease. This is absolutely not the way to store passwords, you should use a proper salted hash algorithm.

Is there a solution in your response? If you only point out issues and not solutions, you are of no help to the situation.

Solution to what? You cannot convert a variable length character string to a fixed length binary field and expect to be able to convert it back to its original string. And, as I already mentioned, this is not the way to manage passwords, your system is wide open to hacking. See Secure Password Authentication Explained Simply[^] for how to do it properly.

He's trying to tell you how to do this in a correct manner which, incidentally, will NOT require padding.

manual session id assignment

Has anyone figured out a way to assign a session ID manually

I have a cart program, in which the cart items are stored by session ID. I send them a email saying you still have items pending for checkout, they click the link with the session id and there cart loads.

At the moment, I'm picking up the new session id and changing the old session id. But if they do it twice, the link stops working.

I was thinking maybe I can force the old session ID if they use a different computer.

FYI:
I have a new program that eliminated this problem, I just need to support the old program for at least 6 more months.

If it ain't broke don't fix it

I ended up writing this which works on all my devices and multiple browsers that have never been to the website.

But 1 strange things occurs ...
It works on all my devices, Win10 using Firefox, Edge, Chrome and my iphone 6S+ using Google Inbox and Safari, Firefox

But it doesn't work downstairs on the other internal subnet where the complaints come from.
Seems every time I fix a bug or mistake, improve something, the changes never reflect downstairs and I get yelled at.
I don't know if this is some evil spirit or something, but I do need to figure this out soon.

Any ideas welcomed, even an exorcist.

//Use the old Session ID, Destroy the Cookie and redirect them
m_Context.Session.Abandon()
m_Context.Response.Cookies.Add(New HttpCookie("ASP.NET_SessionId", ""))
Dim manager = New SessionIDManager()
manager.RemoveSessionID(m_Context)
Dim addCookie As Boolean = False
manager.SaveSessionID(HttpContext.Current, m_sessionID_OLD, False, addCookie)

Dim currentUrl As String = m_Context.Request.Url.GetLeftPart(UriPartial.Path)
m_Context.Response.Redirect(currentUrl)

If it ain't broke don't fix it

Don't use the Session ID to identify users in this way, it's not suitable as you're finding out. Generate a GUID for people and store it in a cookie and use the GUID to identify people\carts.

Query regarding IIS Thread Pool Settings in Machine.config

Hi,

Currently I am working on fine tuning the IIS 8.5 settings.

The CPU is 6 core and RAM is 16 GB

I have set all the Perfmon counters for general and IIS as per below link :

http://www.monitis.com/blog/important-iis7-counters/

Now after observing the Perfmon, I found that ASP.NET\Request Wait Time is taking more than 5 seconds.

So I need to fine tune the Thread Pool settings in machine.config as in below link :

http://geekswithblogs.net/StuartBrierley/archive/2009/09/30/tuning-iis---machine.config-settings.aspx

Currently there is no thread pool settings in machine.config, it is <processmodel autoconfig="“true”">.

So please advise that can I update the thread pool settings as below :

Thread pool setting in Machine.config

maxconnection 12 * #CPUs

maxIoThreads 100

maxWorkerThreads 100

minFreeThreads 88 * #CPUs

minLocalRequestFreeThreads 76 * #CPUs

As I need some basis to change the default Thread Pool Settings.

Or what Perfmon counters should I need to study in-order to change the default Thread Pool Settings.

Please suggest.

Thanks in advance.

Hi,

I am new to ASP.NET. I would like to know how to create a page with a side bar, which is tree like. There are two tables with a one to many relation.

That suggests you're using a commercial component, and you've only purchased a license to use it until June next year.

If you want to extend that date, then you will need to purchase a new license.

first of all thank you very much sir for your response.
sir i want to design a web page where from anyone can ask any question of any subject for eg maths.
suppose someone want to ask about solution for (a+b)2 [a plus b whole square] then how he/she can type 2 as superscript, and other symbols like integration, differentiation etc.

Richard MacCutchan9-Jul-17 20:46

9-Jul-17 20:46

You cannot type those symbols on a standard keyboard, without using multiple keystrokes, which are difficult to remember. You should use the standard operator symbols as defined in most modern programming languages, e.g. 7.2.1 Operator precedence and associativity (C#)[^]. For subscript and superscript on web pages see HTML sub tag[^].
