Register file extension with custom exe

[Guest]

I have an exe console app that i wrote, which works on custom data files. I'd like to give these data files a custom extension and somehow register that file extension with my exe, so all i have to do is double click the data file and my exe will launch.

How do you register an exe with a file extension

Once this is done, and you double click the file with the file extension, how does the exe know which file was clicked? is the path passed into the exe as one of the args in the Main function

Thanks

Hi,

Indeed, the location of that file gets passed as one of the args in the
Main function.
Usually such kind of associations are done by the installation script.
Also, the user can associate a specific file type with an application. Of
course, you can implement the code to associate the file type by yourself:

For the begining I would suggest you to associate that file type manually,
by using the Explorer. This way you could inspect the parameters which get
passed to your application and the registry keys.

You can read more about the file associations here:
