Problème API GetOpenFileName

Bonjour,

Dans l'API GetOpenFileName (ouverture de la boîte de dialogue
donc)
Ça marche si je choisis un fichier pour mettre dans une PictureBoxe,
mais: Si je ferme par la croix [X] rouge, ou <Annuler> ou <Alt+F4>,
ben ça me ferme l'appli, il doit y avoir des params de retour à
rediriger pour éviter ça, mais je ne sais pas lesquels, avez-vous une
idée, voici le code (une tartine cette API):

Bonjour/soir,

Ce code semble être celui de la faq.
Il s'agit donc d'une fonction qui retourne une valeur (la variable

est inutile)
Il suffit de stocker le résultat de la fonction et si ce résultat est une
chaine vide, on sait qu'on a annulé.
Note que la procédure à un paramètre permettant de passer des flags.

il est inutile de le hardcoder dans la fonction.

Dim strFichier As String
strFichier = OpenFileDialog(Paramètres, dont le flag)

If Len(strFichier) Then
'Traitement si fichier
Else
Unload Me
End If
