    Open file with program by default..

    hey...i'm curious about the whole "file type associations" thing. like, if you have a filetype windows doesn't recognize, you can assign whatever program to be the default one to open it. but when your writing your program, say we're going to text files | a text editor, what would you code into the editor so that you could double click the file and it would be opened with the program? similar to how when you double click on a .txt file, its opened in notepad (/ default txt editor)?

    thanks

    Our good freind Magos made a "Java runner" which associates his program with the .class extension.

    yes, but...when a file is double clicked, i want my program to open it. lol not for it to simply open my program and then i have to open the file once in my program. i'll take a look at it, but i need code for automatically opening the file for my program.. lol i'm not word about file type associations.

    I think you when you open a file, the program the it opens with is passed the file name as a command line argument. So you would just need to handle command line arguments appropriately

    Ummmmmm....

    Tonto has already supplied the code you need. Can't ask for more than that.

    Find and read the

    RegisterExtention()

    function in the link provided.



    Or am I missing something?

    I don't recall you asking how to handle command-line arguments, so... no it's not.

    Code:
    int main(int argc, char *argv[]);
    That's the main prototype.

    argv is an array of strings. Each string is one of the tokens entered at the command line. argv[0] points to the name of the program as it was called. argv[1] is the first comman-line argument, and so forth.

    argc is the number of tokens that were entered.

    Command line arguments?! You never mentioned that . Well, such things are also covered in Magos' code too. Because there's no argc/argv in WinMain, you can use the lpCmdLine argument, or the GetCommandLine() API, and the tokenize it like argv does, the CommandLineToArgvW API.
