Zeichnen Sie auf dem Monitor, auch wenn eine andere Anwendung in C# Vollbild ist ⇐ C#

[Anonymous]

Zuallererst, Hallo, das wird meine erste Frage sein. Ich wünsche Ihnen einen guten Tag. Wenn ich zu meiner Frage kommt, wird das Schaffen eines speziellen Fadenkreuzes in CSGO oder CS2 unterstützt. Leider wird dies in alten CS -Spielen wie CS 1.6 nicht unterstützt. Aus diesem Grund möchte ich mit C#ein spezielles Fadenkreuz direkt auf den Monitor zeichnen. Wie kann ich dieses Problem lösen? Wie kann ich auf den Bildschirm zeichnen, auch wenn eine Anwendung Vollbildschirm ist? Ich lasse meinen Code unten, danke im Voraus. < /P>
