Register Windows program with the mailto protocol programmatically

Download this blogpost from https://codegive.com
registering a windows program with the "mailto" protocol allows your application to handle email links. when a user clicks on an email link (e.g., "mailto:[email protected]"), windows will open your program to compose an email. in this tutorial, we'll show you how to register a windows program with the "mailto" protocol programmatically using c# as an example.
note: before proceeding, make sure you have a c# development environment set up, such as visual studio.
start by creating a new c# project or use an existing one. we'll assume you have a basic understanding of c# programming.
to register your program with the "mailto" protocol, you need to specify this in the application's manifest file. follow these steps:
in the app.manifest file, locate the application section and add the following lines:
this code tells windows that your application is capable of handling the "mailto" protocol.
now, let's handle mailto links when your application is invoked. you can do this by listening to the command line arguments passed to your program.
in your c# code, usually in your main method or a dedicated event handler, add the following code to process mailto links:
this code checks if your program was invoked with command-line arguments and processes any mailto links it finds.
build your application and run it. it should now be registered with the "mailto" protocol. you can test it by clicking on a mailto link from a web page or another application. your program should launch and handle the email link appropriately.
that's it! you've successfully registered a windows program with the "mailto" protocol and added code to handle mailto links programmatically. you can extend this code to open a mail composer window or perform other actions as needed in your application.
