Creating Custom Protocol Links

Custom Protocol Links

We can create custom protocol links that can carry out operations as per the configurations
For example: <a href="mailto:as@b.c">

Similar to the mailto protocol we can create our own protocol. In my case I created one that would launch an application when this link is clicked. I had to start a project in my solution based on certain conditions. So I created this custom protocol that would start the project based on the requirements.

Create an entry in the registry as follows 



Add a new string value to the command folder with the path to the .exe file that needs to be launched

ex: "C:\mine\sample.exe" "%1". The %1 denotes that we will be passing parameters to the main method . The parameters will be received inside the string[] args in the main Method of the program.

Creating a custom MIME TYPE


Windows Registry Editor Version 5.00

[HKEY_CLASSES_ROOT\.msg]
    @="msg_file"

[HKEY_CLASSES_ROOT\msg_file]
    @="MSG"

[HKEY_CLASSES_ROOT\msg_file\shell]

[HKEY_CLASSES_ROOT\msg_file\shell\open]

[HKEY_CLASSES_ROOT\msg_file\shell\open\command]
    @="\"C:\\AtomHandler\\handle.exe\" %1"

[HKEY_CLASSES_ROOT\MIME\Database\Content Type\application/msg]
    "Extension"=".msg"

ASp.net core 3.1 identity

It is just an extension to cookie authentication. We get a UI, Tables, helper classes, two factor authentication etc. Even EF and its database constructs. So instead of writing code for all of this we can just use these in built features. Extending Default Identity Classes Add a class that inherits from    public class AppUser : IdentityUser     {         public string Behavior { get; set; }     } Also change the user type in login partial.cs under shared folder Then add migrations and update db using migrations. We can customize further.  services.AddDefaultIdentity<AppUser>(options =>              {                 options.SignIn.RequireConfirmedAccount = true;                 options.Password.RequireDigit = false;           ...
