Eğer hem 32 bitte hem de 64 bitte çalışsın derseniz o zaman şöyle yapın:

#If VBA7 Then
Private Declare PtrSafe Function GetDesktopWindow Lib "user32" () As Long
Private Declare PtrSafe Function GetDC Lib "user32" (ByVal hWnd As Long) As Long
Private Declare PtrSafe Function GetDeviceCaps Lib "gdi32" (ByVal hdc As Long, ByVal nIndex As Long) As Long
Private Declare PtrSafe Function ReleaseDC Lib "user32" (ByVal hWnd As Long, ByVal hdc As Long) As Long

#Else

Private Declare Function GetDesktopWindow Lib "user32" () As Long
Private Declare Function GetDC Lib "user32" (ByVal hWnd As Long) As Long
Private Declare Function GetDeviceCaps Lib "gdi32" (ByVal hdc As Long, ByVal nIndex As Long) As Long
Private Declare Function ReleaseDC Lib "user32" (ByVal hWnd As Long, ByVal hdc As Long) As Long
#End If
