Resources for Windows Application

  • Resources are created automatically by default by VS.Net for Windows forms. They can be plain text files for string resources or XML files for string and binary resources.
  • You can select language for each form and have different layout for each language.
  • This creates satiellite assemblies for each language which are used by runtime depending on the culture selected.
  • Each satellite assembly resides in a culture specific folder which uses ISO naming convention for e.g. for UK English it will be en-GB and for US English it would be en-US.
  • There is no code in the resource dll.
  • Main assembly will use resourse dll in sub directories e.g. en-GB\assemblyName.resources.dll.
  • You can add custom resources.
  • Naming convention for custom resource file [resourceType].[culture].resx. This way the culture specific custom resouce files will be compile in the satellite assemblies [undocumented feature].
  • Resouces files are deployed in \[culture] fodler for windows forms and \bin\[culture] folder for asp.net.
  • You can access culture specific resource using ResourceManager.GetResourceSet(cultureInfo)
  • If the resource manager can't find the specific culture resource, it will fall back to neutal resource. For e.g. en is neautral resource for en-US, en-GB or en-CA.
  • If resource manager can't find netural resouce it will fall back to invariant resouce which is located in main aseembley.
  • A resouce manager bases its resource lookup based on the current thread's UI culture.

How to detect HTML5 support for a browser?

HTML5 has introduced lots of new cool  tags . Not all the browsers support all tags and also the implementation of these tags may be different for each browser. HTML5 specification defines the functional aspects of these tags and not the implementation. Also the general concensus is that by 2022 all browsers will support all new features of HTML5. Of all the modern browsers, Chrome seems to have implemented most, if not all, featutes of HTML5. IE9 supports few. Firefox sits in between. So as a developer how do you make use of the cool HTML5 features without causing any compatibility issues with existing browsers? Traditionally developers have used User Agent to detect browser type and use the features accordingly. However these days, you can easily change a User Agent by using addons in your browser. So you need a more robust way to detect the features supported by the browser as the same engine of two different versions of a browser might support different features. To detect t

How to deploy Lambda function in AWS from developers machine?

  In previous post , we saw how to setup local development environment and test a Lambda function locally. As a developer, you may want to test the function in AWS environment quickly to make sure your code is working. In this post we will look at how to deploy the function in your AWS account. We will look at CI/CD pipeline to automatically build and deploy Lambda function in next post.  If you followed the instruction in previous post , you will notice there are three files in your solution LambdaEntrypoint.cs - This is the entrypoint for AWS Lambda.  aws-lambda-tools-defaults.json - This is the configuration file used by Lambda tooling. Update this file to add AWS profile you created while configuring AWS CLI and region you want to deploy your code. Note make sure you have this setting in your template as for some reason, it is missing from default template.  "function-runtime" : "netcoreapp3.1" , serverless.template - This is CloudFormation Serverless applicatio

When to implement IDisposable?

In .Net, garbage collector is very good at cleaning up managed resources. Managed resources are object implemented using .Net framework and something that the Garbage collector is aware of. Unmanaged resource is anything that is implemented outside .Net framework and Garbage collector has no information about it. The combination of Destructor and Dispose can be used to release unmanaged resources for e.g open files or database connection. If you are not using any unmanaged resource, there is no need to implement IDisposable. Garbage collector will take care of release the unused objects and freeing up the memory.
