就相当与接图，但要用VB代码写

Private Declare Function ReleaseDC Lib "user32" (ByVal hwnd As Long, ByVal hdc As Long) As Long
Private Declare Function OpenClipboard Lib "user32" (ByVal hwnd As Long) As Long
Private Declare Function EmptyClipboard Lib "user32" () As Long
Private Declare Function SetClipboardData Lib "user32" (ByVal wFormat As Long, ByVal hMem As Long) As Long
Private Declare Function SelectObject Lib "gdi32" (ByVal hdc As Long, ByVal hObject As Long) As Long
Private Declare Function DeleteDC Lib "gdi32" (ByVal hdc As Long) As Long
Private Declare Function BitBlt Lib "gdi32" (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 CreateDC Lib "gdi32" Alias "CreateDCA" (ByVal lpDriverName As String, ByVal lpDeviceName As String, ByVal lpOutput As String, lpInitData As Long) As Long
Private Declare Function CreateCompatibleDC Lib "gdi32" (ByVal hdc As Long) As Long
Private Declare Function CreateCompatibleBitmap Lib "gdi32" (ByVal hdc As Long, ByVal nWidth As Long, ByVal nHeight As Long) As Long
Private Declare Function CloseClipboard Lib "user32" () As Long
函数：
Sub ScrnCap(Lt, Top, Rt, Bot)
rWidth = Rt - Lt
rHeight = Bot - Top
SourceDC = CreateDC("DISPLAY", 0, 0, 0)
DestDC = CreateCompatibleDC(SourceDC)
BHandle = CreateCompatibleBitmap(SourceDC, rWidth, rHeight)
SelectObject DestDC, BHandle
BitBlt DestDC, 0, 0, rWidth, rHeight, SourceDC, Lt, Top, &HCC0020
Wnd = Screen.ActiveForm.hwnd
OpenClipboard Wnd
EmptyClipboard
SetClipboardData 2, BHandle
CloseClipboard
DeleteDC DestDC
ReleaseDC DHandle, SourceDC
End Sub

能带点注释吗？好多看不懂？还是先谢谢了

Private Declare Function CreateCompatibleBitmap Lib "gdi32" (ByVal hdc As Long, ByVal nWidth As Long, ByVal nHeight As Long) As Long
Private Declare Function SelectObject Lib "gdi32" (ByVal hdc As Long, ByVal hObject As Long) As Long

Private Sub Form_Load()

Me.AutoRedraw = True
End Sub


Private sub command1_click()

Dim hBitmap As Integer
hBitmap = CreateCompatibleBitmap(Me.hdc, 0, 0)
SelectObject Me.hdc, hBitmap


end sub

这个简单......

用API函数嘛，声明可以查的，函数的方法自己找找资料就可以了，《API资料》里有这个程序的，你参考一下吧~~~

api 声名
bitblt
getdc
桌面dc 为 getdc(0)
用vbsrccopy 复制

谢谢大家的帮忙现在问题决绝了~
