Open File With Program Crashes RRS feed

  • Question

  • I understand that when you open a file with a program, the file name is sent to Environment.CommandLine. I have not been able to test as my program crashes whenever I click on a file that is associated with my program. I created an installer and setup a file association using Visual Studio's setup project. For starters, how can I debug this? Can I specify a debug session that starts in a program? Or is there a known issue with how setup projects creates file associations?

  • I was able to open with by sending the file name to the command line. But it works fine in the debugger. Is there something wrong with file associations in the setup project? My program works fine after being installed, it just crashes when I try to open its file with the program by clicking on the file in Explorer.

  • Ya I got it. I've just been away from internet for a while. Debugging revealed that the command line changes so that I cannot load content. Anyway I worked around it by specifying the program directory for content instead of wherever the program starts.
