    CREATEFILE function

    Guys, i need to know something, can someone clarify it for me ?
    in the function CreateFile() i created, the following is an example
    Code:
    CreateFile(ofn.lpstrFile,GENERIC_READ,FILE_SHARE_READ,NULL,OPEN_EXISTING,0,0)
    CreateFile(filename,GENERIC_WRITE,0,NULL,CREATE_ALWAYS,FILE_ATTRIBUTE_NORMAL,0);
    Ok, this is something i need to know. How can i make a file, lets say .txt file as a hidden mode ? Another thing is, can i give my file an extension of its own, lets say .retard ? is it possible, maybe .ret, more appropriate. Because i dun wan the users to open the file and if they do, my program could open it for them instead. Is this achieveable ?

    Use FILE_ATTRIBUTE_HIDDEN as the second last argument to CreateFile. If the file already exists you can use the SetFileAttributes function. Hidden files are usually anti-social and many users set Explorer to show hidden files.

    The file name you provide to CreateFile can have any extension (excluding bad characters and length restrictions).

    A user can open and read the files they control. Only malware would seek to take away this right.

    >> my program could open it for them instead. <<

    You can setup a file association so that your program will be activated when a user double clicks on a file with the specified file extension.
