WinForms-ProgressringAnim.cs

// The progressringAnimation Timer object is placed in a form (WinForms designer), and has an Interval of 30.
// The progressRing Label object has its Font property set to the Setup font.
// In case you are using the Segoe Boot Semilight font, make sure to check the character codes!
// There's better ways to do this, this was my solution back in 2015.

// This is the "first frame - 1" character code. You can get the character codes with the Character map.
char code = "\ue051"[0];
