J'ai trouvé une façon de le faire (qui n'est sans doute pas la meilleure mais bon ...)
Voici le code : "
Option Explicit
Private Declare Function BitBlt Lib "gdi32.dll" ( _
ByVal hDestDC As Long, _
ByVal x As Long, _
ByVal y As Long, _
ByVal nWidth As Long, _
ByVal nHeight As Long, _
ByVal hSrcDC As Long, _
ByVal xSrc As Long, _
ByVal ySrc As Long, _
ByVal dwRop As Long) As Long
Private Declare Function GetDesktopWindow Lib _
"user32.dll" () As Long
Private Declare Function GetDC Lib "user32.dll" ( _
ByVal hWnd As Long) As Long
Private Const SRCCOPY As Long = &HCC0020
Public Sub SaveMSChart(ByRef Pic As PictureBox, ByRef PicD As PictureBox, _
ByRef mform As Form, ByVal mChart As MSChart, _
ByVal mFileName As String)
Pic.Visible = False
Pic.AutoRedraw = True
Pic.Width = Screen.Width
Pic.Height = Screen.Height
PicD.Visible = False
ScreenShot Pic
mform.ScaleMode = vbTwips
Dim XU As Double, YU As Double
Dim XD As Double, YD As Double
XU = mform.Left + (mform.Width - mform.ScaleWidth) + mChart.Left
YU = mform.Top + (mform.Height - mform.ScaleHeight) + mChart.Top
XD = XU + mChart.Width
YD = YU + mChart.Height
Pic.ScaleMode = vbPixels
PicD.AutoRedraw = True
PicD.ScaleMode = vbPixels
PicD.Width = (XD - XU)
PicD.Height = (YD - YU)
XU = XU / Screen.TwipsPerPixelX
YU = YU / Screen.TwipsPerPixelY
XD = XD / Screen.TwipsPerPixelX
YD = YD / Screen.TwipsPerPixelY
Dim numX As Integer, numY As Integer
For numY = 0 To CInt(YD - YU)
For numX = 0 To CInt(XD - XU)
PicD.PSet (numX - 1, numY - 1), _
Pic.Point(numX + CInt(XU) - 1, numY + CInt(YU) - 1)
DoEvents
Next numX
Next numY
SavePicture PicD.Image, mFileName
End Sub
Private Sub ScreenShot(Pic As PictureBox)
BitBlt Pic.hDC, 0&, 0&, Screen.Width, _
Screen.Height, GetDC(GetDesktopWindow()), _
0&, 0&, SRCCOPY
End Sub
"
En fait, la fonction prend une capture d'écran,
et localise l'objet par rapport au bord.
On peut sûrement remplacer les lignes :
For numY = 0 To CInt(YD - YU)
For numX = 0 To CInt(XD - XU)
PicD.PSet (numX - 1, numY - 1), _
Pic.Point(numX + CInt(XU) - 1, numY + CInt(YU) - 1)
DoEvents
Next numX
Next numY
par la méthode Render pour aller plus vite,
mais je ne sais pas bien m'en servir.
Pic et PicD servent juste pour la fonction.
par exemple :
Module.SaveMSChart Me.Picture1, Me.Picture2, _
Me, Me.MSChart1, "C:\monfichier.bmp"
Voilà, j'espère que cela te conviendra.
