using SqlSettingsProvider with asp.net - asp.net

We want to move our asp.net settings from web.config to a database. All of the examples I see for SqlSettingsProvider are Winform apps.
Can SqlSettingsProvider be used with asp.net?
If not, can someone suggest an alternative?
Thanks

According to MSDN the SqlSettingProvider attribute can only be used for classes derived from ApplicationSettingsBase. As this class is Windows Forms specific and this is stated explicitly in the documentation it means you cannot use this functionality in a web context. (See http://msdn.microsoft.com/en-us/library/8eyb2ct1.aspx for details).
To work around this and get similar functionality I would advise you to create a custom SettingsProviderBase class and implement the setting storage strategy that you need. Using this approach will also allow you to unit test the classes that are depending on application settings.

Asp.net Core 2 Domain dependent View selection?

I have a new multi-tenant web application in ASP.NET Core 2.0, single DB.
I've established a method of determining a particular request's 'TenantId' by examining the domain in a simple piece of middleware.
I've also established a DataContext which applies TenantId filters to applicable tables as needed.
The last thing I'm unclear about is how I can differentiate Views/partial views based on the TenantId whilst sharing the controllers.
I think some scheme where the app first looks in some kind of TenantId sub-folder for the customized tenant's view and if it can't find it, it goes through the regular steps to locate the view... might work okay? Is this a reasonable approach? In other words, it should use the specialized tenant view if it exists, otherwise use the default view.
Would this involve building a custom view engine of sorts?
I've tried something similar with tenant based Html fragments, but it was a pain maintaining it, so I'm looking for something more straight forward on this project.
I'm open to other suggestions of how to implement this functionality as well.
Thanks in advance!
You don't need a whole custom viewengine, you can implement an IViewLocationExpander to make it check various locations for views.
In my project I have mutliple tenant support with both shared themes and tenant specific themes. I can override any view by dropping a copy below the theme folder, ie the main view could be Views/SiteAdmin/Index and I can override it in /pathtothemes/themefolder/SiteAdmin/Index
You can see my implementation of IViewLocationExpander here.
How you register your IViewLocationExpander is like this:
services.AddMvc()
.AddRazorOptions(options =>
{
options.ViewLocationExpanders.Add(new cloudscribe.Core.Web.Components.SiteViewLocationExpander());
})
.SetCompatibilityVersion(CompatibilityVersion.Version_2_1)
;

Symfony2: Where do I place my univeral helper class

I'm new to Symfony2 and would like to know the proper place to put my universal helper class. The helper class contains things like removeCurseWords, uplodFile, resizeImage, watermarkImage, convertDateToServerTime, doStuffHere and other things used by many but belong to none. I want this class to be accessible to all the bundles in my app so where do I place it to make it available to all.
Group those methods and put them in services (see http://symfony.com/doc/current/book/service_container.html). That way you can use them cross-bundle via the service container. You could have one service for all image operations and one for the rest which doesn't fit elsewhere.
If you have your php Library i suggest you to write a bundle that wrap it for symfony2 usage for, as example, expose the functionality as services container, manage the initialization, implement for type and so on for enable your library in yhe symfony2 way, then you can share via composer in other projects.
See this for further details.
Hope this help
I always create a folder called "Utils" at the same level as Controllers, Repositories, etc Found several people doing it that way too.

Asp.net form validation using Validation configuration file

Currently I have a requirement to validate(server side) forms in ASP.net (not MVC). We have several fields in our form which gets data from active directory. Instead of using inbuilt .net validation control, the requirement was to use a configuration setting for all validations, which can be easily edited.I am planning to use XML(or any other similar alternative) as configuration Editor.
Initially I thought (still thinking) this is simple task to achieve. But when I searched for similar implementation, i couldn't find one. Some of the implementation which i saw uses a very complex approach. The whole idea was to keep the validation settings as simple and as dynamic as possible.
I would appreciate if anyone can direct me to a similar implementation or give suggestions with respect to this.
After some research I found this article very useful. It introduced me the validation block in Enterprise Library 5.0 which can be customized as per our requirement.

ASP.NET: How do I create a widget/user control that can be used with other solutions?

I am looking to create a widget that can be used with other solutions. The widget is a competition widget that can be placed in different parts of the site.
What is the best way to do this? Should I create a new solution to hold this in?
Create a new class library project (you can have it within your current solution if it suits) and create your server controls in there. You can then reference this library from whatever websites you need.
You need to create a Web Control, not a User Control, if you want o use it in other projects. This question details the different control types, you may find it useful:
What is the difference between UserControl, WebControl, RenderedControl and CompositeControl?
Here is relatively simple tutorial on creating a custom WebControl:
Create ASP.NET Server Controls from Scratch
And here some more advanced example from MSDN:
Developing Custom ASP.NET Server Controls
It depends if you will be using it in other solutions really. If you are, then if might make more sense to create a new widgets solution with each widget in its own user control and compile it into an assembly.
Then you just reference that assembly and use it in your markup.
If your widget is only going to be used in a single solution then I wouldn't bother with the above. Just create a user control in the same solution.
As opposite of some answers, you should create user controls with embedded resources.
It is complex to do it, but once you do you will be able to develop controls like RadControls from Telerik.
If you open up their controls you will see that they are all embedded resources on the Telerik.Web.UI.dll.
Here is an old answer of mine that shows how to load the control and how to handle embedded resources (virtual path provider)
Unless you have a good reason to do so (like creating a generic control as a calendar, grid or something like that) don't go this way, it is dark, complex... But as you can see it might be worth it, Telerik.Web.UI is the live example that this can work out.

Automated Flex testing without static AutomationIDs

Has anyone had any luck testing a Flex app without static Automation IDs attached to components? All of the elements in the apps are generated .....
We've investigated FlexMonkey but it appears to be incompatible with any app that utilizes the ExternalInterface. RIATest's scripting language leaves much to be desired...
Thanks-
Jonathan
Unfortunately I don't know much about this kind of stuff, but I went to a talk that presented these tools for TDD:
- Hudson
- Flex Unit 4
I guess there are tutorials online, don't know if it helps with ExternalInterface testing.
Is there anything that prevents you from generating appropriate automationNames for your generated components? This way you should be able to refer to them properly in automation tools.
Are there any other non-changing properties that your generated components have, like maybe 'id'? If so you can use these properties to address the components. This is definitely possible in RIATest.
FunFX is a Flex automation tool that allows you to access components via ID, "automation name", "automation value" or index. While using something like the component index might be less than ideal for robust tests, if that's all that's stable, it might be worth a try. And it's written in Ruby, so that should satisfy any "real programming language" related requirements. :)
We added an "automationPrefix" property to many of our custom controls (particularly those that are reused many times on a single screen), and wrote code to append the beginning of the automationName property on any child controls. Setting the automationName was the most important parting of enabling automation testing on our Flex apps. There are several ways you could modify the automationName to be unique without making it completely static at the level that most test automation packages need it. We are currently using QTP as the test automation tool of choice.
