Associating a file with my application - Reg

Post by rajan_m » Fri Jul 03, 2009 9:22 am

Hi, :)

I'v written (wxWidgets)application program in windows platform, which will read the content of a input file(for eg,txt) specified by user and do some processing :| .

My Requirement:
when i double click the input file it has to trigger the aplication program and has to do the processing :shock: .

Note:
:idea: I'v associated the input file with my appliction simply through choose program dialog, so when i double click
input file is triggering the exe :D .
Is there any way to get the input file path within myapp::OnInit() :cry: , so that i can get the input data to proceed with.
Every exit is an entry somewhere else!

Setting a file association is not normally done from within a program. It's more common to set file associations using the installer. For instance, I use InnoSetup for my Windows installs, and in one part of that install process I set registry entries that associate file types with my app.

If you're curious about that method, you can look here:

I suppose you could always modify the registry entries in code, but that's bad form because when your app is uninstalled the file associations don't go away.

rajan_m, you can use the argc and argv (wxApp members):

Code: Select all

bool myApp::OnInit(){
    wxString filename;
    if (argc == 2){ // Check if there is just one argument
        filename = argv[1];
        // do processing
    }else{
       // use the open file dialog
    }
}
