I have a WPF application that does a number of things. When running the app, I can go to File > Open, browse to a file, and open it in the app. Fields on the UI are updated with values from the file and everything works great.
The file I am opening contains binary data and has a custom file extension that is associated with my application. The problem is that if I DON'T have the WPF application running and I double click one of my associated files, it simply opens the application. I would like it to open the application and then load the contents of the file I clicked on. How can I go about doing this?
I have looked into using the Application_Startup event handler in the App.xaml.cs but cannot get the filename when double clicking on it as my StartupEventArgs are empty. However, the sender.ToString from Application_Startup handler returns "MyCompany.MyApp.App". How can I get the filename and go about loading it?
Another thing is that if I put a breakpoint in the Application_Startup event handler and double click my associated file, I never hit the breakpoint. The only way I hit the breakpoint is when I run the application from the IDE. I would like to be able to double click a file, then hit the breakpoint so I can do some debugging.
Thanks in advance.
