Bonjour à tous,
Sa fait trois heures que je chipote sur ce code et j'arrive pas à trouvé le noeud du probléme.

Dim ExStyle As Long
ExStyle = GetWindowLong(MainApp.hwnd, GWL_EXSTYLE)
If ExStyle <> (ExStyle Or WS_EX_LAYERED) Then
ExStyle = (ExStyle Or WS_EX_LAYERED)
Call SetWindowLong(MainApp.hwnd, GWL_EXSTYLE, ExStyle)
End If
WndSetOpacity = (SetLayeredWindowAttributes(MainApp.hwnd, &H8000000F, 100, IIf(ByAlpha, LWA_ALPHA, LWA_COLORKEY)) <> 0)
End Function |
Je remplace la valeur crKey par une couleur, je passe ByAlpha en False, Malgré ça il met toute ma FORM en transparence. Ce que je désire c'est seulement la couleur que j'ai défenie.
Merci à vous tous.
