Hi ich habe mal ein bischen mit Directx programmiert und das ist hier mal was ganz einfaches.Es soll nur eine Line zeichnen.Aber wenn ich es kompiliere und ausführe beendet es sofort das soll es aber nicht.Hab schon alles ausprobiert vielen Dank für Hilfe

Vielleicht solltest du doch erstmal die WinAPI bzw. C/C++ Grundlagen lernen..
Guck dir einfach mal deinen Einstiegspunkt an und denkt dir dann Schritt für Schritt was passiert oO

Dir fehlt eine Schleife in der Main. Sobald die Main zu ende ist, hört auch dein Programm auf zu laufen.
Ein wenig Pseudo-Code zur veranschaulichung:int WinMain(...) { ErzeugeFenster(); ErzeugeNötigeProgrammteile(); while(ProgrammNichtBeendet) { FrageEventNachrichtenAb(); VerarbeiteEvents(); Render(); Logik(); } }So sieht im groben eine Programm-Schleife aus.
ZIeh dir unbedingt ein Win32 Tutorial rein oder, alternativ, kann man auch wxWidgets oder QT zur Fenstererzeugung nehmen.

Mir war grade langweilig:
