[VB] Screen Dump

[Carmen]

Hi all,I've try to use the following code to write a PrintScreen function and save it to an image,
however, the image saved is not the instant one, but from the last PrintScreen, why is that?
How to solve it? Thanks

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 Function SaveScreen(ByVal theFile As String) As Boolean
On Error Resume Next

'To get the Entire Screen
Call keybd_event(vbKeySnapshot, 1, 0, 0)

'To get the Active Window
Call keybd_event(vbKeySnapshot, 0, 0, 0)

SavePicture Clipboard.GetData(vbCFBitmap), theFile

SaveScreen = True
Exit Function
End Function

Private Sub cmdEnd_Click()
Call SaveScreen("C:\Windows\Desktop\shot1.gif&quot
End
End Sub
