Private Const COPY As Long = 1054
Private Const CONNECT As Long = 1034
Private Const DISCONNECT As Long = 1035
Private CapHwnd As Long
Private Sub Command1_Click() '截图按钮
On Error Resume Next
SendMessage CapHwnd, GET_FRAME, 0, 0
SendMessage CapHwnd, COPY, 0, 0
Image2.Picture = Clipboard.GetData
Clipboard.Clear
End Sub
Private Sub Form_Load()
'打开摄像头
CapHwnd = capCreateCaptureWindow("WebcamCapture", 0, 0, 0, 320, 240, Me.hwnd, 0)
