Hello Friends , Recently I made a simple text editor that enables you to Type, Save ,Open ,Edit , Change font etc.. I made separate buttons for them. Everything is working fine but I am stuck at a point. I want a .txt file to be opened by my standalone application. When I go to the file properties, then openWith and choose my editor.exe. The .txt file doesn't seem to open with my application. Although when I open a file using the dedicated buttons it works fine. What should I do ?.
