Salut
j'ai cre� un fichier crystalraport "test1.rpt" qui contient deux param�tres;
l'une est une date d1 et l'autre chaine C1,je veus passer deux valeurs au param�tres pr�cedent a partir de programme c++.net(2005) pour qu'il affiche les donne�s celon ces 2 valeurs pass�
comment puisse je le faire ?
merci
