I am thinking to create a web service for a SQLDB, I have created a simple database with two three tables tbldestination, tblflights and tblbooking.my big problem is how can i enable my database to be accessed through web service?

I know I can allow the web service access to Session variables by adding (EnableSession=true). Is there a way to allow it access to global Application variables?
I have several resource intensive variables that are loaded in the Global.asax and I need access to there in the webservice.
I have just started building an asp.net web service with visual studio 2005. However whenever i try and run the site i get this message, saying "debugging failed because integrated windows authentication is not enabled". I am at a loss of how to correct this problem.
View 1 Replieshow can I enable database logging in my ASP.net application?
I am using VS2010 (ASP.net MVC2 Project) and would like to see logging that highlights database activity between the application and the database, including database connection establishment (as I do have a connection related error somewhere).
I'm using SqlServer Express 2008.
I am trying to create Web Application using ASP.Net via Visual Studio 2010. The Database that I use is Access, with connection Method OleDb
When using the query "Update" or "Delete", the programs shows no errors, but the data in Access does not change.
While for query "Select" and "Insert", the data is displayed and inserted successfully.
The Following code is the sample query "Delete" that I used..
Code:
Imports System.Data.OleDb
Partial Class frmTEst
Inherits System.Web.UI.Page
Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
[Code] ....
Previously I tried a direct query using AccessDataSource, but the result just the same, Update and Delete can't be done. But the Select and Insert can be executed successfully.
Is there any problem with my Access configuration or whether the problem is in the coding itself..?

I know there are a couple of posts about this already, but I still can't figure it out.
I'm using Table Adapters method called GetBBNewsByNewsID with the following SQL query:
SELECT Description

Is there a way how I can check programmatically which user is used when my application accesses resources?
I have a production system which only our admin can access. Sometimes it is not clear what part of the system is wrong: Lets say when logging is not working. It is always possible that the web.config is wrong, but sometimes the directory is not accessible. It would make my life easier if I could be sure, that the user is used, that I expected.
I have some geo targeting code whcih I want to behave in a particular way if the site is being spidered by a robot e.g. google etc.
Is there any way to infer this?
I have a Menu page. If a user selects an Menu Item it opens a new IE Window using JavaScript. So user can open different parts of applications in multiple IE Windows. These Windows have the same Session.
My issue is that these pages are accessed synchronously? If one of the child window is waiting for an action to be finished no other request from any other child window is processed. Is it because of using Session variables?
Update: This is only happening to the windows having the same parent. If I have IE child windows from different parent windows then this issue is not there.
There is a UserControlA which was already developed when I joined on a project. It is in a Project which I will call MyProjectWeb and it's namespace is MyProjectWeb.Common.
[code]....
But to my surprise, I cannot create an instance of UserControlB in the same code file in WorkFlowManager. MyProjectWeb.Common namespace does not even contain a UserControlB. When I compile I get obviously get a The type or namespace name 'UserControlB' does not exist in the namespace 'MyProjectWeb.Common' (are you missing an assembly reference?)
Why is that I can reference UserControlA but not UserControlB which are in the same namespace from the WorkFlowManager cs file? If I access the MyProjectWeb.Common namespace anywhere inside the MyProjectWeb, I can see both the user controls. Anywhere to look for errors?
i am using MVC for my project in the logon authentication, when i login using correct values there is no problem.
If i login using false or empty values i get the DataContext accessed after Dispose error.
i get it in the first line itself 'using (HealthObjectDataContext dc = DataContextFactory.GetDataContext())'
this is the method i use in the security service.

I am running into an odd problem, and this is the only thing I can think of. I'm storing a list in cache, and I am randomly losing items from my list as users use the site. I have a class that is called that either goes to cache and returns the list from there, or if the cache is over a certain time frame old, it goes to the database and refreshes the cache. So when I pull the data from cache, this is what it looks like....
results = (List<Software>)cache["software"];
And then I return results and do some processing, filter for security, and eventually it winds up on the screen. For each Software record, there can be multiple resources attached to it, and based on how the security goes they may see some, all, or none of the records. So in the security check it will remove some of those resources from the software record.So my question is.... when I return my results list, is it a reference directly to the cache object? So when I remove a resource from the software object, it is really removing from cache as well? If that is the case, is there any way to not return it as a reference?
edit: I think I may have just answered my own question.... so if I do something like this:
results = new List<Software>((List<Software>)cache["software"]);
it will copy the cached list to my results list, correct?

View 2 RepliesI am finding it quite awkward. I have registered the user controls and they are actually being parsed as I can view the controls I have placed on them. Problem is that I cannot access them in code behing. Even when I place them, their tags are not represented in the intellisence drop down. What could be causing this? I am placing them on a page residing in a master page setting. The controls are declared on the child page.
View 2 Repliesi have the following problem: i work in web application and only today. any control i put on the page, when trying to access it from behind code. it doesn't appear at all. what are the probabilities and reasons for this problem. note:i work from a thin client. they make some maintenance on their server today. and after that i find this problem.

Have I done something wrong ?I am running a web-site with simple .aspx files on a standalone workgroup Windows Server 2008 called 'Max'.I had assumed that the .aspx files were accessed by the 'Network Service' account.The application pool for the website is running with 'Network Service' as the process account.I was puzzled, since 'Network Service' had no permission on these .aspx files, and I coudln't understand how these files were being accessed at the file level.So I added event level auditing to the files, and I was suprised to learn that the .aspx files were being accessed by an account called Max$ (ie the computer account).Is this correct ?Why is the Network Service account not being used ??
View 11 RepliesWe have created an ASP application with MS Access as back end. We have implemented this web application on our server machine and accessed the same from on my local machine.
Our application works fine when only one user accesses it (All insert, update works fine). But when multiple users connect to this application and try to update the database, then application get crashed. As per our knowledge, this is happening because of access database get locked, when one user open it in exclusive mode.
