I am trying to create an application similar to a quiz engine. I was wondering if I need session variables to store information between different pages or I can pull the data directly out of textboxes.I am using C-sharp,dot net and WPF.
View 4 Replieshow to POST to a php file form a vb.net app: http:[url].... So now I've logged in the user user by posting their username and password to the php file, the php file then does security/checks they exist/etc and if both username and password are correct is stores the user ID in a session variable.Now if the vb.net app tries to download data off a page which needs the user to logged in, it checks this by doing:
if (!isset($_SESSION['uid'])) {
header("Location: index.php");
}
However after having logged correctly in the app the session variable is not set.How does session work with a vb.net app like this?When the user logs in successfully should I download the user id and keep it in the vb.net app and then post it to each page that requires authentication?

View 1 RepliesI have an ASP.NET application that I am developing. I'm using session variables within the app.In Firefox & Chrome, they all work.But in IE (ver 9), there's one variable that's not working. I'm not sure if it's a storage or a retrieval (or both) at this point. The variable in question that I'm storing is a List(T) type. It's the only one of it's kind that I'm using. Can't help but think there's a correlation there.One other old post mentioned the possibility that cache is causing the problem, but I didn't understand the answer very well.

Are there any libraries available that to change the look-and-feel of Desktop Applications made using VB.net 2008? Here is a snapshot of an application that runs on Windows 7:I think its made using the .net framework, but how can it be styled like this? PS - Even if its not built using .net framework, then please let me know which language supports the UI customization on windows platform.

View 5 RepliesI have a problem with a large application that consists of windows forms mainly, but some WPF windows and controls (we also use DevExpress controls v9.1). The problem is that the application sometimes hangs when it runs in a remote desktop session, and that session gets locked due to inactivity, and the user comes back and unlocks the session. The hang seems very similar to the hangs you get when accessing GUI controls from a none GUI thread, but I'm pretty sure that's not what causes the problem. (We had a lot of those problems earlier, and have fixed all multithreading problems we were able to find. And the hangs now never occures when the application runs outside the remote desktop environment.)
I've done a lot of research on the problem but I've still not found a clear point to what causes the problem. However, I think there might be a problem related to some combination of remote desktop and .NET framework. The reason for this is posts like this:

View 29 RepliesI'm planning to use some session variables on an intranet ASP/VB.NET page, and want to make sure that I'm not missing out on anything important I should know, or that I have my information mixed up. So here's what I (think) I know about session variables.They:are stored on the server, so if I have a lot of users then they'll each be using some more memory which could lead to a slowdown.are inaccessible by the user unless I expose access. hang around/persist across user requests (i.e. each time the user makes a request from the page the data will still be there - until it times out). This also means that I need to make sure that the variable doens't have "left over" data in it.
Is there anything that I've got totally wrong, or anything I'm missing? I'd prefer not to get bitten by a bug down the road because I think I understand what's going on.

I've got a problem losing session variables in an ASP/VB.NET application. The application allows searching for an item or it can show an item if provided with a unique link (in the browser). It holds information about the item in session variables. In the webpage showing an Item a user can click a button which opens a window with additional information about the item - obtained from a session variable. When I search for the item using the search engine and click the button - it works OK.
When I copy the link to a browser: the item is shown, however clicking the button returns a 'null exception' - the session variables with information about the item are lost. Moreover when I provide the link for the second time the button works, the variables are there!
I have a gridview and use a session to pass the variables from the page to an edit page. This works perfectly, until you search for a number. When you search the correct record displays in gridview, but when you click edit, it passes the wrong record.

Session("wr_id") = GridView1.Rows(e.NewEditIndex).Cells(2).Text & "~/~" & _
GridView1.Rows(e.NewEditIndex).Cells(3).Text & "~/~" & _
GridView1.Rows(e.NewEditIndex).Cells(4).Text & "~/~" & _

I realize not all of the code is pasted in here, because it would take too much space. Any Ideas? I'm guessing it has something to do with e.NewEditIndex

View 2 RepliesI have a web application that allows a user to view family members.
When the user clicks on a family member, it displays the member's basic info. There is also a grid displaying that family member's related family members. (e.g. User can click on the Father link. From that popup, they can then click on the Father's Father link, then click on the Father's Father's Grandson link, etc.).
To reduce the number of popups that appear on the screen, I want to prevent the user from continually clicking on family links past three members.
What is the best way to keep track on how many data forms have popped up? Or can this reliably be done with a web application?
I have an MVC application which sets some session variables based on internal static IP addresses.I have built an ApplicationController to override the OnActionExecuted sub in MVC for data that I need to use throughout my application.However, the code below, which is just a snippet of my code but is edited for my post, only partially works. On initial page load, the session variables aren't saved, but after a page refresh they are. The issue I have is that these need to be saved on the initial page load.
If Session("Item1") = Nothing Then
If IpAddressShort <> "" Then
Dim locInfo = cmsRepository.GetInfoBasedOnLocation(IpAddressShort).SingleOrDefault()
If locInfo IsNot Nothing Then
[code]....
Theoretically, if I'm correct, if there is no Session("Item1") set/if Session("Item1") is empty, then the rest of the snippet should run and set those variables.How come this isn't setting those variables on the first time the page load?
Is there a way to set session variables during login that are then available to reports? We have a reporting services server where we move and denormalize data from our transaction system for reporting purposes. In order to allow our users to login with the same user name and password from the transactional system we have set up custom forms authentication and after much trial and error it is finally working. In addition we have the authorization accessing our transactional system so that any changes in user authority is immediately reflected in Reporting Services.
Our problem now is that we would like to add some additional features such as locking down parameters depending on user authority/groups in our transactional system. We have found a way to do it but it's inefficient, basically we have stored procedures that will query our transactional system to check for access. The problem is that these queries will often be run for every report request even though the answer is unlikely to change. It would be nice to have access to session level data that can be set once during log in and then accessed from the reports.
Record keyboard inputs to fill forms. This feature will allow users to record keyboard sequence
View 1 RepliesIn our projects we use setting variables to store user setting for the applications. Moreover, with every latest version of the applications, we upgrade these variables to retain user settings.Normally, this works fine, but recently one of my end user reported an error i.e.Configuration System failed to initialize". The error is related to user.config file. Therefore we requested the user to send us his file.After received the folder, we noticed that it contains 3 files (3begfjb.newcfg,3begfjb.tmp and user. config). 3begfjb.tmp is an empty file, while 3begfjb.newcfg and user.config are identical files. We tried to open these files but the data in user.config isn't proper xml rather its unreadable formatted file.Do any you guys had experienced this sort of issue or any ideas how and what may have created these files and corrupted user.config file.
View 3 RepliesI 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.
