Detect ASP Session State Type From Code?
Jun 7, 2010
I'm trying to track down a problem on our test environment. Previously it was set to use InProc Session State Type, but I've added in the SQLServer type for one specific Web App. I did this because we use the SQLServer type in our production environment and I want our test env to match as closely as possible.
However, after changing it to SQLServer I do not get any errors when trying to store unserializable data in session like I would expect. It works just fine, even though I would think it shouldn't. I'm a relative newbie when it comes to configuring this, but from the various tutorials I googled, I thought I covered all the bases.I was wondering if there's any code snippets to verify which session state type an application is actively using.

I'm looking for some smart ideas on how to quickly find all usage of session state within an existing asp.net (MVC) application.
The application in question was the subject of outsourced development, and has been running fine in production. But we recently realised that it's using InProc session state rather than (our preferred route) StateServer.
In a small scale test, we switched it over to StateServer, and all worked fine. However, when we deployed to production, we suddenly experienced a large number of errors. I'm not sure if these errors were caused by this change (they were actually complaining about database level problems), but removing the change allowed the application to function once again (this may have just been because it caused a recycle to occur).
So before I try switching it again, I'd like to perform a thorough audit of all objects being placed in the session (I'd previously taken a quick look at a couple of controllers, and they seemed fine). If I had full control over the code, this is the kind of place where I'd just comment out the class (to compile and find the various ways of reaching the session class), then comment out the accessors, hit compile, and visit each error. But I can't do that with built in .NET framework types.
I decided to try using Reflector. I've analyzed the "Used By" for each of the following:
System.Web.HttpSessionStateBase.set_Item(String, Object) : Void
System.Web.SessionState.HttpSessionState.set_Item(String, Object) : Void
System.Web.SessionState.HttpSessionState.set_Item(Int32, Object) : Void
[Code]....

I have several sessions stored at one time, and i want to count a particular one:
i have session.contents("session1") and session.contents("session2")
but i only want to check if there is anything in session2...
I tried this:
If Session.Contents("session2") = "" Then
as in, if theres nothing in it, then do something. But... it says when there is nothing in session2, that theres no object reference, i want to do something like this:
session.contents("session2").count or something

I have an uploadify control working fine in a vb.net web application - however whenever I switch on cookieless session state in web.config (cookieless="true") - it stops working. In my upload IHttpHandler I can see that the data stored by uploadify is nothing:
[Code]...
I'm guessing that the flash isn't honoring the session id in my url? how to keep uploadify working when I turn on cookieless session state?

I have a Dynamic Data application to which I have added a class for extending EDM. Everything works great, but now I am trying to set an entity property value equal to a value in session state - and its not recognizing the Session command. I'm trying to do something like this:
audit.action_by = CStr(Session("person_name"))
I think this is because I do not have the class Inheriting Page, but if I do add Inherits Page it breaks other stuff. How can I have the class include the ability to utilize sessions directly without inheriting Page?

I have a bit of strange behaviour in an asp.net web application that involves the session state being lost.
Process A user logs into the application and the session is set. They then fill out 1 field, and the application then does an AJAX POST to a .asmx web service. Within the web service, I am using a HttpWebRequest to grab data from another server.
This data is then output to the browser.A few more fields are then filled in, and the data is then again Post to the same web service via an AJAX POST.

I can get the local computer name on a RDC session using Environment.GetEnvironmentvariable("ClientName") if the application is 32 bit and Server is 32 Bit or when app is 64 bit and server is 64 bit
How can I get the local computer name from a 32 bit application when the server is 64 bit
Environment.getEnvironmentvariable("ClientName") returns an empty string

I was investigating on Google wether there was any sort of code that would return the current state of a laptop's 'lid'. I need to be able to find the state of the lid and be able to execute code before the defined event in Windows Power Management is executed.I have come across ExCreateCallback and stuff on MSDN however I wouldn't have the faintest on how to implement it into VB.

I'm using ASP.net 4.0 VB,I am using a session variable to add a user entered code into the url of each page. I can get the code to show up at the end of the page's URL that my textbox is on, but what do I add to every page to make sure that the session stays at the end of every URL that person visits during their session? This is the code from the page that the user enters their user code.
Protected Sub IBTextBoxButton_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles IBTextBoxButton.Click
Session("IB") = IBTextBox.Text
Dim IB As String = Session("IB")
End Sub
[code]....
This is what I have in the page load of one of the other pages. What else do I add to make sure that variable is added to the URL of that page?
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Dim IB As String
IB = Session("IB")
End Sub

Im trying to grasp session varibles, i understand what they are etc but i would like to know how to define a type for each session variable.Iv written it like this
Session("Title") = txtTitleContent.Text
How can i tell it what type of value is going to be in it, because at the moment im only playing about with strings, but what if i have an integer and want to pass it back to the back end to save it will throw an error saying "conversion from string to integer is not valid" should i use Cint to deal with this?

In visual studio (VB environment), for exemple, with point structure, while debbuging, in state of displaying {system.drawing.point} at the object value, its display the X and Y value.For exemple :

A spy on pt will show "{X = 8 Y = 9}"So i want :
Dim cust1 as cust_type1
to display me something differente than "{namespace.cust_type1}"

I am storing an array of a custom serializable class in session on my site. When a page on the site changes, suddenly it renders them invalid, and tells me that it can't cast the type to it's own type. I assume the class version numbers are changing or something?!
I'm not trying to redesign this whole process.
Unable to cast object of type 'ShipmentPackages[]' to type 'ShipmentPackages[]'.
Description: An unhandled exception occurred during the execution of the current web request. review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.InvalidCastException: Unable to cast object of type 'ShipmentPackages[]' to type 'ShipmentPackages[]'.

I'm trying to detect if a value is a decimal type and insert it into a DB. If the value is a decimal, I want to continue with the inserting. If the value is not a decimal I want to insert "0" as a value to the DB.
For this I created a function seen below... What is wrong with it?
Function IfNotDeci(ByVal Arvo) As String
If Arvo is Decimal = True Then
Return Arvo
[Code]....
The problem is on the first "If". How to know if the value is a decimal?
(I need this code because my values are read from different excel-files that are not always correct. So if a human didn't write a decimal value to a cell, the program should not respond with an error, but just insert a "0".)

So, let's say I have this code (VB.Net)[code]...
What I don't like is:
- relies upon reflection
- loosely typed (no compile time checking)
- I'd rather store the binding information somewhere other than ID, but don't know where else it could go within the aspx definition. Moving the binding declaration to the code behind would be better in some ways, but worse in others.

I am storing a session variable that a user types into a textbox. With their valid input, their session gets created and they get a little more functionality than the regular end users of the site.I was wondering if it is possible to find a way to add someone's session variable to the end of a URL. This way we can email a link to one of our clients, they click it, and their session has automatically begun. They already have the textbox to enter their code into, but I was told that it would be much easier for the users to just click a link that will start their session.

How do I determin if a user has given me what I am asking for in terms of data type.
Example if my prompt to the user say "Give me a number of double data type"
How can I tell that the user entered a double xx.yy?
Or if I am testing for integers and I get user input ABC.GH?
I know about CDbl and CInt and CStr but these don't work unless data is provided. Also how do you test if the conversion took place? Also how do you differencate between 12.00 being integer?

I have had several occasions recently to access a specific class several times over a relatively small time frame.So I've been storing the value of the class in Session and trying to access it on page load, if it's not available creating a new instance and storing that in session.
So instead of constantly replicating the same code for different classes on different pages I'm trying to create an extension method to do this for me.
[Code]...
I'm stuck on what to do when I make my new instance of my class (it would have to have a New() sub)
I'm not sure where to go from here... or even if this is the best way to do it.
