I am developing a windows application with c#. I need to get the file and folder name when I right click on a file to use for other functions. Right now I have made the registry keys to get my application running. When I right click on a file (word, ppt, txt, etc) my context menu shows the option I added, Set Perm. When that is selected my windows application opens up. In a text box on the form, I want to display the full file name and path. Is there a way to do that? I've added %0 and %1 in the registry to the end of the argument to launch my app, but it does not work. I've tried h:\temp\myapp.exe %1 and h:\temp\myapp.exe %0. Putting the %1 or %0 in quotes did not change anything. I am in Windows 8 using Visual Studio 2017. Thanks.
