fenetre windows (none)Résolu

Question

Bonjour tout le monde  ,

J'ai un ptit probleme... Je sais creer une fenetre normale avec l'API Windows, mais je voudrais en creer une qui n'a pas de barre au dessus (NONE) et qui s'etend sur tout le bureau, ne laissant que la barre demarrer d'en bas (ptet MAXIMISED).Pourriez vous me donner un exemple pour une telle fenetre. J'espere avoir ete assez clair sur mon probleme  .

Merci beaucoup

Salut,

Ci-dessous un bout de code complet en C permettant d'afficher une fenetre sans barre de titre. Par contre, je ne me suis pas pr&#233;occup&#233; des questions de dimension de cette fen&#234;tre.

Ce qui est vraiment important est en rouge (cr&#233;ation de la fen&#234;tre).
