我想使用vba截取屏幕截图（然后将其作为电子邮件附件发送）。理想情况下，我想截取只有活动表单的屏幕截图。有没有办法做到这一点？

您必须使用Windows API调用才能执行此操作。以下代码适用于MS Access 2007.它将保存BMP文件。

使用raj的示例获取图像然后将其保存
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
