The main idea is totally based on Bradley Grainger's blog entry posted back on September 22, 2008. Shortly after, Stefan Olson built Bradley’s code (incorporating a few improvements) into a new Visual C++ application and shared it in a blog post on November 27. Unfortunately, his post is no longer available, although it can be retrieved using WayBackMachine here.

This project continues Bradley's and Stefan's efforts incorporating some minor tweaks:

• Splash image, application to be launched and fadeout time are all retrieved from an external plain text file. It could be easily adapted to JSON files if a JSON parser (such as rapidJSON) is included.
• The splash screen is closed during the fadeout whenever the launched application is closed (the WM_QUIT message posted from the launched application is handled by the splash screen).
• The C++ version is ported to assembly (for the smallest and fastest possible executable) and some basic OOP is implemented.

Instructions

1. Set the splash screen application icon in the corresponding resources.rc file and then compile any of the 3 versions.
2. Create a text file named settings.txt and place it in the same folder as the splash screen application. Write 3 text lines:
   • Path (either absolute or relative) of the splash image. The resulting absolute path should be less than 260 characters long.
   • Path (either absolute or relative) of the application to be launched. The resulting absolute path should be less than 260 characters long.
   • Time in miliseconds for the fading out of the splash screen (typically 500 or less).
3. If launching a WinForms app, use this code in the form's shown event to signal the fading out of the splash screen:

private void Form1_Shown(Object sender, EventArgs e)
{
    using var closeSplashEvent = new System.Threading.EventWaitHandle(false, System.Threading.EventResetMode.ManualReset, "CloseSplashScreenEvent");
    closeSplashEvent.Set();
}

4. If launching a WPF app, use this code in App.xaml.cs to signal the fading out of the splash screen:

protected override void OnStartup(StartupEventArgs e)
{
    Dispatcher.CurrentDispatcher.BeginInvoke(DispatcherPriority.Loaded,
                (DispatcherOperationCallback)delegate { CloseSplashScreen(); return null; },
                this);
    base.OnStartup(e);
}

private void CloseSplashScreen()
{
    using var closeSplashEvent = new System.Threading.EventWaitHandle(false, System.Threading.EventResetMode.ManualReset, "CloseSplashScreenEvent");
    closeSplashEvent.Set();
}
