How Do I Create a Splash Screen in a Windows Forms Application?

Building a Splash Screen for Your Windows Forms App

A splash screen is a valuable tool in Windows Forms applications, offering visual feedback during the application's startup phase. This temporary window provides progress updates or branding information while the application's core components load.

Here's a step-by-step guide to creating a splash screen:

1. Design the Splash Screen Form: Create a new form, removing the border by setting ControlBox, MaximizeBox, MinimizeBox, and ShowIcon properties to false. Set StartPosition to CenterScreen for optimal initial placement.
2. Configure Form Appearance: Set FormBorderStyle to None. Ensure the form's MinimumSize and MaximumSize match its initial size to prevent resizing.
3. Show and Hide the Splash Screen: Strategically choose the lifecycle events to control the splash screen's visibility. The application's main routine or the main form's Load event are ideal candidates.
4. Perform Background Initialization: While the splash screen is visible, execute any required initialization processes (e.g., database connections, file loading).
5. Close the Splash Screen: Once the primary application form is fully loaded, close the splash screen form.
6. Optimize for Animation (Optional): For animated splash screens, implement double buffering and handle initialization tasks off the main GUI thread using a BackgroundWorker to prevent UI freezes.
