Description

salu

voila, une fois j'avais essayé d'utiliser un controle UpDown, mais il fallait le mettre puis paramétrer en fonction de quel textbox on voulait qu'il soit.... enfin.
en voila un qui regroupe le text et les boutons, c'est donc beaucoup plus simple.

placez en un sur la form puis paramétrez Max, Min et Value.
En fait il s'utilise comme un slider ou un progressbar.
l'evenement change survien quand la valeur a été modifié.

voila, je met le code pour qu'il apparaisse dans la compil.

Source / Exemple :

laissez moi vos commentaire.

PS : je fairai des MAJ, notemment pour pouvoir modifier les couleurs.
