C# WinForm - loading screen -

i ask how make loading screen (just picture or something) appears while program being loaded, , disappears when program has finished loading.

in fancier versions, have seen process bar (%) displayed. how can have that, , how calculate % show on it?

i know there form_load() event, not see form_loaded() event, or % property / attribute anywhere.

all need create 1 form splash screen , show before main start showing landing page , close splash once landing page loaded.

class splashform {     //delegate cross thread call close     private delegate void closedelegate();      //the type of form displayed splash screen.     private static splashform splashform;      static public void showsplashscreen()     {         // make sure launched once.          if (splashform != null)             return;         thread thread = new thread(new threadstart(splashform.showform));         thread.isbackground = true;         thread.setapartmentstate(apartmentstate.sta);         thread.start();                }      static private void showform()     {         splashform = new splashform();         application.run(splashform);     }      static public void closeform()     {         splashform.invoke(new closedelegate(splashform.closeforminternal));     }      static private void closeforminternal()     {         splashform.close();     } ... } 

and main program function looks this:

[stathread] static void main(string[] args) {     splashform.showsplashscreen();     mainform mainform = new mainform(); //this takes ages     splashform.closeform();     application.run(mainform); }
