Bonjour, j'ai choppé une api sympa qui est drawtext, qui peur etre très utile au lieu d'un label etc
Par contre j'ai bcp de mal à m'en servir.
Je cherche Quelqu'un sur vb france capable de m'expliquer:
comment placer le texte( je n'arrive pas, ni DT_VCENTER, etc, j'ai tout essayé, le texte reste au meme endroit)
j'ai reussi a définir son pt de commencement avec RECT mais le reste
... donc si qn pourait me fournin des bonnes infos, merci bcp:D

et aussi des que je passe une fenetre par dessus, le texte drawtext
s'efface et réapparait seulement sous action. c'est pas une question de
autoredraw??
