C'est due à quoi?

**Slumpy** · 07/06/2007, 11h10

Bah je comprend pas ta question. C due au fait qu il n y a rien dans ta textbox et que t essayes d appliquer CDec a ... rien.

Arf, encore trompé un coup t as 2 et un coup 3 sorry ...

**loverdev** · 07/06/2007, 11h12

Le champ vide c'est "txtre2emetrim" et le champ rempli c'est "txtrea3emetrim"

**Slumpy** · 07/06/2007, 11h15

est ce que t sur qu il y a un truc dans la 3 ?

**loverdev** · 07/06/2007, 11h18

J'explique la situation: J'ai 5 champs "txtrea1ertrim", "txtre2emetrim", "txtrea3emetrim", "txtrea4emetrim" et "txtmontantavance". Les 4 1er champs peuvent être remplis ou vides ou quelques uns remplis et d'autres vides. Je veux que lorsque j'essaye de remplir le champ "txtmontantavance" il ne m'affiche pas cette erreur comme indiqué ci-dessous.

un cdec ne marche que si la chaine contient un nombre
" " n'est pas un nombre
donc tu try
valeur = cdec(chaine)
catch
valeur = 0
end try
et valeur est bien un nombre que tu peux mettre dans ton champ
