I have a class in my asp.net proj, I would like to get access GetGlobalResourceObject (that page exposes), from anywhere in the site, possible?
In other words I wanna access the global resources from a class that is not a page I don't care how.
Answer:
Yes, as following pseudo:
Resources.<The name of the resources file name>.<your resource key>;
Example:
lblTitle.Text = Resources.MySettings.WebsiteTitle;
Resources is an Visual-Studio auto generated namespace that exposes all the global resource classes and props in the project.
You should use
HttpContext.GetGlobalResourceObject("myResourceKey")
...because that way it will still work when using a custom ResourceProvider. The default type-generator for Resource files explicitely uses the Resx provider and won't work if you implement something like a database provider.
On some farms you'll need to wrap the call to
HttpContext.GetGlobalResourceObject("myResourceKey")
inside a try/catch block to get it over the "Could not find any resources appropriate for the specified culture or the neutral culture" error.
If you are in the site you have access to HttpContext and can use:
HttpContext.GetGlobalResourceObject("myResourceKey")
I kinda took this from the resource designer,
ResourceManager temp =
new ResourceManager("Resources.<<resource name>>",
System.Reflection.Assembly.Load("App_GlobalResources"));

Here is the context :
Each user of my application belongs to a company.
Parameters for each company are defined inside "company.yml" configuration files, all of them sharing the exact same structure.
These parameters are then used to tweak the application behavior.
It may sound trivial, but all I'm looking for is the proper way to load these specific YAML files.
From what I understood so far, using an Extension class isn't possible, since it has no knowledge about current user.
Using a custom service to manage these configurations rather than relying on Symfony's parameters seems more appropriate, but I can't find how to implement validation (using a Configuration class) and caching.
Any help would be greatly appreciated, thanks for your inputs!
Using the Yaml, Processor and Configuration components of Symfony2 should fit your needs.
http://symfony.com/doc/current/components/yaml/introduction.html
http://symfony.com/doc/current/components/config/definition.html
Define your "CompanyConfiguration" class as if you were in the DependencyInjection case
Create a new "CompanyLoader" service
use Symfony\Component\Yaml\Yaml;
use Symfony\Component\Config\Definition\Processor;
$companies = Yaml::parse('company.yml');
$processor = new Processor();
$configuration = new CompanyConfiguration();
$processor->processConfiguration($configuration, $companies);
Now you should be able to use your companies array to do what you want
Have a look at http://symfony.com/doc/current/cookbook/configuration/configuration_organization.html as well as http://symfony.com/doc/current/cookbook/configuration/environments.html. If that's not the correct answer you'll have to be more specific on what your company.yml configuration contains.
1) We are using OpenEJB (both embedded and standalone) with a few deployed EJBs. We would like to specify some simple static business rules and values (example: icon_size=200). Normally, we would put them in a regular properties file (example: rules.properties). Since we shouldn't access the file system directly while inside the application server, is is possible to place those key-value pairs somewhere inside the ejb-jar.xml?
2) If not, is there a standard mechanism to do this? What is it?
Thanks
Use env-entry. In XML:
<env-entry>
<env-entry-name>icon_size</env-entry-name>
<env-entry-type>java.lang.Integer</env-entry-type>
<env-entry-value>200</env-entry-value>
</env-entry>
In annotation:
#Resource(name="icon_size")
int icon_size;
I personally just use a .properties file; well a TernarySearchTree which reads in .properties and .XML files and allows quick retrieval. These files are available at application level. However you can in EJB 3 inject env-entry elements into your EJB. This link explains it in good detail Injection of env entry
There are some OpenEJB extensions here that might be useful.
env-entries.properties
Check out the Custom Injection example which is basically allows the <env-entry> to be specified as plain properties in a META-INF/env-entries.properties file. Nice for collapsing all those name & value pairs into a simple properties file. Internally, we just generate the xml for you using those properties. The default type is always java.lang.String, which is good for this next part.
java.beans.PropertyEditor support
Any <env-entry> which is of <env-entry-type> java.lang.String will automatically have its type converted using the VM java.beans.PropertyEditor for the target type. That's also how Spring does the converting. There are few built-in converters, such as #Resource java.util.Date myDate and #Resource java.io.File myFile
So I have Test1.aspx, Test1.aspx.vb. The LocalResource files, in the App_LocalResources folder, Test1.aspx.resx and Test1.aspx.es.resx. I also have a class called TestTheData.vb in the App_Code folder.
Now what I want to do is call GetLocalResource("stringObjRes").ToString in the TestTheData.vb class. The method however is not showing up in Intellisense. When I try to type manually, I get the error lines in my code.
I've imported:
Globalization
Threading
Threading.Thread
Web
Web.UI.Page.
No luck. So how I am supposed to do this....?
Well it seems that Local Resources can't be accessed in files that are in the App_Code folder. So I used Global Resources instead.
I know it's 1 year old but I just added the comment if some others are also searching for this:
Your guess is right, you cannot access the Local Resource Object from another class. GetLocalResourceObject only exists within the code of the page, in your case Test1.aspx.vb. If you are calling the class function from your Test1.aspx.vb you could of course retrieve the Local resource from there and then supply it to your TestTheData.vb as a parameter. But if you need the 'stringObjRes' in several places (not only in Test1.aspx) then a global resource is of course preferred.

So I am working on a project which uses ASP.NET. I am trying to call Cache["key"] but the compiler complains about how System.Web.Caching.Cache is "nat valid at this point".
If I call Cache obj = new Cache(); the obj is always null.
I can access HttpContext.Current.Cache - but this doesnt let me specify an absolute expiration and sliding expiration in the Insert() method.
Can someone help me?
You should be able to absolute or sliding expiration calling the insert on HttpRuntime.Cache. It has several overloads. Ex:
HttpRuntime.Cache.Insert("EXAMPLE_KEY",
exampleItem,
Nothing,
DateTime.Now.AddHours(1),
System.Web.Caching.Cache.NoSlidingExpiration);
The exact same code should also work with HttpContext.Current.Cache.
I suggest you to try PCache class under PokeIn library. Even if you use FREE edition of that library, there is no limitation with this class. It has many more functionalities in comparison to ASP.NET Cache class and you dont have to deal with these problems. there is a simple sample project available on the web site.
I have a class Customer in app_code folder in asp.net web site, how can I create an instance using reflection, for example using Activator.CreateInstance(assemblyName, typeName)? Because the app_code is dynamically compiled, I don't know the assembly in design time?
Thanks
Fred
The question is should be how get a full name of type in design time, I want to put it in web.config. I have ConfigSection type, it is in app_code folder, I need to declare it in configSection. Thanks
You should be able to use "App_Code" or "__Code" as the assembly name in the web.config
I think you can use Assembly.GetExecutingAssembly() to get a reference to the current assembly.
I have solved a similar problem in this way:
Type[] appCodeTypes = System.Reflection.Assembly.Load("App_Code").GetTypes();
You can also use GetType().Assembly if you know that it will be the same assembly as your currently executing code.
