Thread: Help with prog

Hello, I'm going to make a program that first reads from program.ini and then writes what stands inside (when a key is pressed), like, you press f12 and it writes your password directly, 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:
                // The code to write whats inside program.ini
            }
        default:
            return DefWindowProc (hwnd, message, wParam, lParam);
    }

grateful for answer
