Salut
j'ai creé un fichier crystalraport "test1.rpt" qui contient deux paramètres;
l'une est une date d1 et l'autre chaine C1,je veus passer deux valeurs au paramètres précedent a partir de programme c++.net(2005) pour qu'il affiche les donneés celon ces 2 valeurs passé
comment puisse je le faire ?
merci
voici tout le code
