Y at-il un moyen de prendre une capture d'écran dans MS-Access avec vba?

Je veux utiliser vba pour prendre une capture d'écran (qui sera ensuite envoyé en tant que pièce jointe à un email). Idéalement, j'aimerais prendre une capture d'écran de seulement la forme active. Est-il possible de faire cela?

    Vous devez utiliser des appels d'API Windows pour ce faire. Le code suivant fonctionne sous MS Access 2007. Il va enregistrer les fichiers au format BMP.

    Option Compare Database
Option Explicit
Private Declare Sub keybd_event Lib "user32" (ByVal bVk As Byte, ByVal _
bScan As Byte, ByVal dwFlags As Long, ByVal dwExtraInfo As Long)
Private Const VK_SNAPSHOT = &H2C
Private Declare Function OpenClipboard Lib "user32" (ByVal hwnd As Long) As Long
Private Declare Function GetClipboardData Lib "user32" (ByVal wFormat As Integer) As Long
Private Declare Function CloseClipboard Lib "user32" () As Long
Private Declare Function OleCreatePictureIndirect Lib "olepro32.dll" _

IPic As IPicture) As Long

End Type
'\\ Declare a UDT to store the bitmap information
Private Type uPicDesc

hPic As Long
hPal As Long
End Type
Private Const CF_BITMAP = 2
Private Const PICTYPE_BITMAP = 1
Sub PrintScreen()
keybd_event VK_SNAPSHOT, 1, 0, 0
End Sub
Public Sub MyPrintScreen(FilePathName As String)
Call PrintScreen
Dim IID_IDispatch As GUID
Dim uPicinfo As uPicDesc
Dim IPic As IPicture
Dim hPtr As Long
OpenClipboard 0
hPtr = GetClipboardData(CF_BITMAP)
CloseClipboard

With IID_IDispatch
.Data1 = &H7BF80980

.Data4(3) = &HAA
.Data4(4) = &H0
.Data4(5) = &H30
.Data4(6) = &HC
.Data4(7) = &HAB
End With
'\\ Fill uPicInfo with necessary parts.
With uPicinfo
.Size = Len(uPicinfo) '\\ Length of structure.
.Type = PICTYPE_BITMAP '\\ Type of Picture
.hPic = hPtr '\\ Handle to image.
.hPal = 0 '\\ Handle to palette (if bitmap).
End With
'\\ Create the Range Picture Object
OleCreatePictureIndirect uPicinfo, IID_IDispatch, True, IPic

End Sub

    Utilisation de raj exemple, pour obtenir l'image et puis cela pour sauver

    Dim oPic
On Error Resume Next
Set oPic = Clipboard.GetData
On Error GoTo 0
If oPic Is Nothing Then
'no image in clipboard'
Else
SavePicture oPic, "c:\temp\pic.bmp"
end if
