What am I supposed to write as CategoryPath to get the file in the App_Data folder?
/// <summary>
/// Summary description for XMLHelper
/// </summary>
public static class XMLHelper
{
public static string CategoryPath = "App_Data/Categories.xml";
public static void InsertCategory(string categoryName, string moderator)
{
XElement cat = XElement.Load(CategoryPath);
I have put a css file in App_Data folder and referrenced it properly in the page to be used. But when I browse the page then it does get loaded and page is shown without styling. Well I know why it is happening because Asp.Net run time blocks access to App_Data folder at run time. But I wanna ask that how we can make it working that is I put the css file in App_Data folder and it still works.
View 8 RepliesI'm currently writing a website in ASP.NET MVC, and my database (which doesn't have any data in it yet, it only has the correct tables) uses SQL Server 2008, which I have installed on my development machine. I connect to the database out of my application by using the Server Explorer, followed by LINQ to SQL mapping.
Once I finish developing the site, I will move it over to my hosting service, which is a virtual hosting plan. I'm concerned about whether using the SQL Server setup that is currently working on my development machine will be hard to do on the production server, as I'll have to import all the database tables through the hosting control panel. I've noticed that it is possible to create a SQL Server database from inside Visual Studio. It is then stored in the App_Data directory.
Does it make sense to move my SQL Server DB out of SQL Server and into the App_Data directory as an .mdf file? If so, how can I move it? I believe this is called the Detach command, is it not? Are there any performance/security issues that can occur with a .mdf file like this? Would my intended setup work OK with a typical virtual hosting plan? I'm hoping that the .mdf database won't count against the limited number of SQL Server databases that can be created with my plan.
I am confused as to what to do with these. I have .cs files in App_Code. I also have other files in App_Data, and Bin. Could I just create these folders, make them virtual directories and upload my files as normal? Or do I need to do something special with these folders/files? Im really stuck on this. Also, this is a "shared hosting" account.
View 5 RepliesDespite using many sql databases before, I've never actually tried to develop an app with a database in the App_Data directory.
It's a small WCF service project, which has a sql express 2008 r2 database.
Working in VS there are no problems, I thought it would be as easy as deploying to a server (win 2008 with sql 2008 r2 installed) and it would just work. But it would appear not.
In the web.config, the connection string which uses |Data Directory| in the connection string.
I read here that |Data Directory| only works in VS, but looking at other articles on the web that doesn't seem to be the case.
I have (for the sake of this) given everyone modify rights on the app_data dir on the server.
I deployed using the package feature in VS 2010.

View 9 RepliesI've an XML file stored in App_Data which is only used to read some configuration on startup. When I attempt to open it within my code, I get an Access to the path ... is denied message.
I'm having trouble understanding why, and how to solve it. I guess in theory I should alter the permissions on the file (and directory), but this hasn't changed anything.
To give a bit more background:1. Its a file bundled with the project, so the setup created by VS2008 writes it to the correct place during install. I didn't think I'd need to do anything unusual post install such that the ASP.NET application would have access.
2. When I've tried publishing this locally, I've not had any problems. - This is only on a test Windows 2003 server.
3. I've ran a simple page to understand the effective user of IIS - It is NT AUTHORITYNETWORK SERVICE. I tried granting "Full Access" to this user to this file, and still it doesn't work.The code to open it is simple:
FileStream fs = new FileStream(Server.mapPath(s), FileMode.Open);
Where s is defined as '~/App_Data/myfile.xml
I've even copied and pasted the full path & filename (from the exception) and tried "dir" on it, and it is indeed present (to get around a typo for example).I've also tried running aspnet_regiis.exe /s
Edit Note: Actuall this is a suggestion related to WebPages and FileUpload Helper in Razor. I am not looking for workarounds. Following this tutorial: [URL] Under "Letting Users Upload Multiple Files" section it says : Because allowMoreFilesToBeAdded is set to true, the helper renders a link that lets user add more upload boxes. Now say you click "Add another file" link as shown and then decide not to upload 3rd file, is there a way to remove that third upload control?

I'm using jQuery tabs, which are initialized from a static .js file using a selector:
$()
.ready(function () {
$('.jqTabsStandard').tabs();
});
I'm using ASP.NET (not that it makes a difference I think), but when I click a button in one of the tabs, is there a way I can re-select that tab when the page reloads. I was thinking of sticking the tab section in an UpdatePanel. I was hoping there's a way I could trigger the tab to reselect.

I have a private static field in my Controller class in an MVC web application.
I have a static method in that controller that assigns some value to that static field, I want to apply lock on that static field until some other instance method in the controller uses the value stored in the static field and then releases it.
DETAILS:
I have a controller named BaseController having a static ClientId field as follows and two methods as follows:-
public static string ClientId = "";
static void OnClientConnected(string clientId, ref Dictionary<string, object> list)
{
list.Add("a", "b");
// I want the ClientId to be locked here, so that it can not be accessed by other requests coming to the server and wait for ClientId to be released:-
BaseController.clientId = clientId;
}
public ActionResult Handler()
{
if (something)
{
// use the static ClientId here
}
// Release the ClientId here, so it can now be used by other web requests coming to the server.
return View();
}
I did some research after posting. All I found was simple examples for no-layer architectures, like connecting to a database from your aspx page, so, in a corporate environment, it is unnaceptable.
I need to call a server-side method (using ASP.NET Ajax) in a 3-layer architecture.
For example, my Default.aspx contains a method LoadProducts().

This cannot change. There is no way to convert Business and Data layers to static.
How can I call the LoadProducts() method using ASP.NET Ajax?

View 5 RepliesTL;DR: Which is likely faster: accessing static local variable, accessing variable stored in HttpRuntime.Cache, or accessing variable stored in memcached?At work, we get about 200,000 page views/day. On our homepage, we display a promotion. This promotion is different for different users, based on their country of origin and language.
All the different promotions are defined in an XML file on each web server. We have 12 web servers all serving the same site with the same XML file. There are about 50 different promotion combinations based on country/language. We imagine we'll never have more than 200 or so (if ever) promotions (combinations) total.
The XML file may be changed at any time, out of release cycle. When it's changed, the new definitions of promotions should immediately change on the live site. Implementing the functionality for this requirement is the responsibility of another developer and I.
Originally, I wrote the code so that the contents of the XML file were parsed and then stored in a static member of a class. A FileSystemWatcher monitored changes to the file, and whenever the file was changed, the XML would be reloaded/reparsed and the static member would be updated with the new contents. Seemed like a solid, simple solution to keeping the in-memory dictionary of promotions current with the XML file. (Each server doing this indepedently with its local copy of the XML file; all XML files are the same and change at the same time.)
The other developer I was working holds a Sr. position and decided that this was no good. Instead, we should store all the promotions in each server's HttpContext.Current.Cache with a CacheDependency file dependency that automatically monitored file changes, expunging the cached promotions when the file changed. While I liked that we no longer had to use a FileSystemWatcher, I worried a little that grabbing the promotions from the volitile cache instead of a static class member would be less performant.
(Care to comment on this concern? I already gave up trying to advocate not switching to HttpRuntime.Cache.)
Later, after we began using HttpRuntime.Cache, we adopted memcached with Enyim as our .NET interface for other business problems (e.g. search results). When we did that, this Sr. Developer decided we should be using memcached instead of the HttpRuntime (HttpContext) Cache for storing promotions. Higher-ups said "yeah, sounds good", and gave him a dedicated server with memcached just for these promotions. Now he's currently implementing the changes to use memcached instead.
I'm skeptical that this is a good decision. Instead of staying in-process and grabbing this promotion data from the HttpRuntime.Cache, we're now opening a socket to a network memcached server and transmitting its value to our web server.This has to be less performant, right? Even if the cache is memcached. (I haven't had the chance to compile any performance metrics yet.)On top of that, he's going to have to engineer his own file dependency solution over memcached since it doesn't provide such a facility.
Wouldn't my original design be best? Does this strike you as overengineering? Is HttpRuntime.Cache caching or memcached caching even necessary?

View 2 RepliesI have the following values: customerNumber, ProductNumber, PartNumber.There exists a directory structure on a server like follows (the bold italic text is the actual value)://myServerName/Parts/Images/CustomerNumber/ProductNumber/PartNumberSo the part of the file directory that is constant is://myServerName/Parts/Images/but the file structure CustomerNumber/ProductNumber/PartNumber will vary, displaying the actual number valuesEX: //myServerName/Parts/Images/11111/22334/007so I need some code that will loop through the file Directory structure under "Images" and will get the string values of each subdirectory. This will be used to find the image to be used for the specific CustomerNumber, ProductNumber and PartNumber.Does anyone have any good sample code where you have done this before?
