Bonjour,

J'ai un morceau de code (dont je ne comprends pas tout) qui me fait une capture d'écran et qui me l'affiche dans un picturebox, mais je voudrais redimensionner mon bitmap car il fait la taille de mon ecran, donc quand je le met dans mon picturebox on ne voit pas tout, voici le code :

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

        r = DeleteDC(hSDC)
        r = DeleteDC(hMDC)
 
        oBackground = Image.FromHbitmap(New IntPtr(hBMP))
        DeleteObject(hBMP)
    End Sub

j'ai essayé :

Code :

oBackground.size = New System.Drawing.Size(584, 416)

dans ton cas je pense que c'est la property sizemode qu'il faut que tu passe en stretch image.

picture.sizemode = PictureBoxSizeMode.StretchImage ;
