    win32 api help

    Hello, I'm going to make a program that first reads from program.ini and then writes it when a key is pressed, like, you press f12, it writes your password, but I've got stuck here:
    Code:
        switch (message)
        {
            case WM_DESTROY:
                PostQuitMessage (0);
                break;
            case WM_CLOSE:
                DestroyWindow(hwnd);
                break;
            case WM_KEYDOWN:
                switch (wParam)
                {
                    case VK_F12:
                    // Here the code must be
                }
            default:
                return DefWindowProc (hwnd, message, wParam, lParam);
        }
    Notice this isn't console app, its win32 api app, grateful for answer

    1) What exactly is the problem you're having?
    2) This may be more appropriate in the Windows Programming forum, depending on the first question.
    3) USE CODE TAGS! Oh... Sorry... Force of habit... YOU USED CODE TAGS! YOU ROCK!

    >>//code goes here<<

    Read this faq and this faq; for a winapi specific solution the file management functions can be found here with a very small example of opening a file for reading and writing on this page. The api's of interest are CreateFile, CloseHandle, ReadFile and, unsurprisingly, WriteFile

    Once you have decided whether you are going for a winapi (windows), c or c++ approach and you have at least a little file io code to work with you should be better placed to direct any future questions to the relevant board.

    For .ini files you can also use WritePrivateProfileString:
    Code:
    WritePrivateProfileString(TEXT("PasswordSettings"), TEXT("UserName"), TEXT("my user name"), TEXT("C:\\Path to\\program.ini"));
    
    WritePrivateProfileString(TEXT("PasswordSettings"), TEXT("Password"), TEXT("my password"), TEXT("C:\\Path to\\program.ini"));
    which will give you something like:
    Code:
    [PasswordSettings]
     UserName = my user name
     Password = my password
    You can read the values back using GetPrivateProfileString:
    Code:
    TCHAR szPassword[128];
    
    GetPrivateProfileString(TEXT("PasswordSettings"), TEXT("Password"), TEXT("Default password"), szPassword, 128, TEXT("C:\\Path to\\program.ini"));

    You mean like this?
    Code:
    {
        switch(Msg)
        {
        case WM_DESTROY:
            PostQuitMessage(WM_QUIT);
            break;
        case WM_KEYDOWN:
            switch(wParam)
                {
                    case VK_F12:
                    WritePrivateProfileString(TEXT("PasswordSettings"), TEXT("Password"), TEXT("my password"), TEXT("Program.ini"));
                }
                 break;
        default:
    
            return DefWindowProc(hWnd, Msg, wParam, lParam);
        }
    
        return 0;
    }
    Didn't worked :\

    Here is the .ini file:
    Code:
    [PasswordSettings]
    Password = my password
    The idea is to type my password when pressing F12
