Access :: Access/SQL Selectcommand And Session?
Nov 22, 2010
I have the following two pages. One is a search page that have a few listbox/textbox/and dropdownlist. The other will be the result page that take from session those 3 data and using an if/else statement to sort out some detail. After that it will form an access/sql selectcommand to search the database base on that 3 criteria. But for some weird reason only the first part of my if and else statement work. Can anyone check and help me out why the rest of the if/else doesn't work. Or point me to another direction?

Is there anything missing in IIS 6.0 that prevents me from (Insert into table) using MS-Access?
Explain: The application works fine under Visual Studio 2008 IDE the insert into table works fine with no error, Also I tested with hosting provider and works fine with no problem. but now I have published the same exact app in a dedicated server windows 2003 with
IIS 6.0 .NET framework 2.0 with latest service pack I gave IIS_WPG write/modify access to the folder where MS-Access database is located and database but at the time of insert an error pop-up. I need to install in the Server or settings in the IIS to recognize my MS-Access db is it some office runtime that I am missing. (BTW I am using OLEDB connection string in my C# )
Using System.Data.OleDb;
I can retrieve data off of it with no problem but when I try to insert is when it fails I thought the problem was Access Rights but I do not think is the case.

Here's a short explanation of my asp.net project.
1) the default page loads, it will read the Windows Login of the user opening the page.
2) I'll check if this login exists in a table stored on the webserver.
In this Access Database, there's a 2nd linked table, pointing to another access table on a network location. Now, I want to read data from this linked table. However, at this moment I receive an error:
"The Microsoft Jet database engine cannot open the file '\<ip><shared-folder>statistics.mdb'. It is already opened exclusively by another user, or you need permission to view its data".
Some extra info:
- The network folder has read and write permissions for everyone
- the user and group permissions on both access files are set to read/modify/administer for the Admin user (on the tables I want to read from)
- IIS authentication on the server is set to "Windows Authentication" (this is needed so I can read the Windows Login from the user). All other authentication modes are disables (like anonymous, ...)
- When the error occurs, no other program or process has access to the statistics.mdb (so, it can't be locked by someone else)
- the web.config files access connection string looks like:
<add name="AccessConnectionString" connectionString="Provider=Microsoft.Jet.OLEDB.4.0;Data Source=\<IP><shared-folder>statistics.mdb;User Id=admin; Password=;" />
Like I said before, in this statistics.mdb file, there are 2 tables. One normal table, and another linked table (pointing to a network location)
Searching for solutions, I discovered the following:
- if I don't use linked tables, everything works fine (however, I have to use this linked table)
- even if I connect directly to the table in the network I receive the error. So, I'm pretty sure I don't have sufficient rights to read from this table.
I read that not the Admin user is opening the file, but actually a user called ASP.NET. This user doesn't have the correct rights to do this. However, I'm not sure if this is true.

I am getting error message:

Without SelectCommand I can compile.

I am trying to get into grips with AJAX/JQuery and MVC. i need to access the session on the controller. This doesnt seem to be initialised at the constructor level but there needs to be a way I can store items in the session in the constructor depending on the parameter values (an extra constructor is written here) I am also doing unit testing here, which has been provided by 3rd party and they are using this extra constructor.
So the idea here is that when the page is loaded, JQuery will request a collection of items (which will be stored in session) and also be able to post to the page so items are added into the collection too. So, what is the best way here to get access to the session in the constructor of a controller?

I have a pagemethod defined with the attribute [WebMethod]. The pagemethod accesses the session with no problem (HttpContext.Current.Session).
However I just read somewhere that in order to access the session in a WebMethod, you need to define it like so: [WebMethod(EnableSession=true)]
So my question is, what gives? How come I can access the session even though I dont have that code? Apparently EnableSession defaults to false if its missing, so I should not be able to access the session. The web application uses ASP.NET 3.5 and uses InProc Cookieless sessions.

I have 2 projects in my solution.
MVC Web application
Class library
The MVC Web application references the class library.
The class library contains a class that extends the default ASP.Net Controller.
I'm putting a variable in session in the application's Global.asax.
protected void Session_Start(object sender, EventArgs args)
{
HttpContext.Current.Session["DomainName"] = Request.Url.Host;
}
In the class library I'm trying to get the value from the HttpContext.Session, but HttpContext.Session keeps coming up null.
[code]...
HttpContext.Current.Session doesn't seem to be an option in controllers.

I'm building a Javascript application and eash user has an individual UserSession. The application makes a bunch of Ajax calls. Each Ajax call needs access to a single UserSession object for the user.
Each Ajax call needs a UserSession object.
Data in the UserSession object is unique to each user.
Originally, during each Ajax call I would create a new UserSession object and it's data members were stored in the ASP.NET Session. However, I found that the UserSession object was being instantiated a lot. To minimize the construction of the UserSession object, I wrapped it in a Singleton pattern and sychronized access to it.
I believe that the synchronization is happening application wide, however I only need it to happen per user. I saw a post here that says the ASP.NET cache is synchronized, however the time between creating the object and inserting it into the cache another Thread could start construction it's another object and insert it into the cache.
Here is the way I'm currently synchronizing access to the object. Is there a better way than using "lock"... should be be locking on the HttpContext.Session object?

I'm trying to use the HttpContext.Current.RewritePath method to serve up different versions of an application to different customers. I would love to be able to look at the HttpContext.Current.Session object to know who it is making the request. Oddly when I go to look at this at the BeginRequest handler, the Session always shows null. I've tried various other events and have had no luck.

I have two projects ,one is webforms and other is Business logic, i am storing username in Session Variable, i have audit module in businss logic which has event handlers to do auditing on object create / remove. i want to store username in audit trail, i want to save username in some global place which is session bounded so that i can get the username in my audit module.i dont want to refer System.web, or httpcontext in my businesslogic project.pls help how i can acheive this. i found this article but cudnt understand much.
"Now one option if you want to have your DLL pull the stuff from Session is to abstract out session. So you could define an interface like IStorage, that your library will know how to use. Then you can have a SessionStorage or MemoryStorage class and use IoC to inject the appropiate class into your library classes. This gives you the freedom to code it how you wanted it to be coded without tying your code to Session. Oh and one other benefit if done properly can be used to not tie your code to session in the web either.

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?

In my ASP.net website we are going to use Silverlight to display some interactive diagrams. The users can add, edit and delete various diagrams on the silverlight front end. Silverlight will call Web Service methods to save the changes into the database. Besides the data being passed by silverlight to web service call, we also need to pass some data from the session (like logged on user id etc.) to the web service call.
My question is that how silverlight can access session data? I am trying to pass session information via a webservice method call over to Silverlight but, the session variables inside the web service methods are returning null value.
The Web Service is running under the same web root where the ASP.net website using Silverlight is also hosted. I have made EnableSession = True for web properties.

Have a project where I need to access a RSS feed. The issue is this RSS feed, you need to be logged in as a user. They have a simple web form (login + password).
1) Post a web form with my login and password
2) Maintaining Session (w/successful login), do an additiional GET to retrieve the RSS feed.
I am doing this in an ASP.Net page so it all happens server side in VB.Net
