I am trying to modify the Windows registry to allow a context menu for certain audio file extensions so that my application can be launched in the specified files. The application is written in Java, but wrapped in an exe wrapper using Winrun4j.
I used this example. How to create a context menu for my software? to try to do it. The depressing thing is this demo adds a context menu for .txt files, and it works, and if I crack the code and add it to my application for the .txt file, it also works. But if I just changed the code for working with audio files, for example .mp3, error messages are not reported, but it does not work, in the context menu for .mp3s
Checking the code to see if a particular group is associated with another application, and whether it affects the value entered in the registry, but both audio files and text files are associated with another application (Audio Vlc, txt, UltraEdit) so this is not a problem. I tried to ignore these applications and add directly to Software / .mp3 / classes instead of Software / Vlc / classes, but that didn't matter.
Here is the result when I run:
