VB.NET怎么調(diào)用攝像頭啊?求實例,最好配注釋啊

Private Const WS_CHILD = H40000000

Private Const WS_VISIBLE = H10000000

Private Const WM_CAP_START = H400

Private Const WM_CAP_DRIVER_CONNECT = WM_CAP_START + 10

Private Const WM_CAP_SET_SCALE = WM_CAP_START + 53

Private Const WM_CAP_SET_PREVIEWRATE = WM_CAP_START + 52

Private Const WM_CAP_SET_PREVIEW = WM_CAP_START + 50

Private Declare Function capCreateCaptureWindowA Lib "avicap32.dll" ( _

ByVal lpszWindowName As String, _

ByVal dwStyle As Long, _

ByVal x As Long, ByVal y As Long, ByVal nWidth As Long, ByVal nHeight As Integer, _

ByVal hWndParent As Long, ByVal nID As Long) As Long

Private Declare Function SendMessage Lib "user32" Alias "SendMessageA" (ByVal hWnd As Long, ByVal wMsg As Long, ByVal wParam As Integer, ByVal lParam As Long) As Long

Private Sub Form_Load()

'建立采集窗口（不顯示窗口，處理后顯示到PIC控件）

uwndc = capCreateCaptureWindowA("", WS_VISIBLE Or WS_CHILD, 0, 0, 320, 240, Me.hWnd, 0)

'連接

SendMessage uwndc, WM_CAP_DRIVER_CONNECT, 0, 0

'Scale開

SendMessage uwndc, WM_CAP_SET_SCALE, True, 0

'顯示刷新MS

SendMessage uwndc, WM_CAP_SET_PREVIEWRATE, 40, 0

'用予覽方式顯示(特殊需要，不顯示予纜）

SendMessage uwndc, WM_CAP_SET_PREVIEW, True, 0

End Sub

上述代碼就可以實現(xiàn) 但是要注意相應的控件是否存在 不存在的 你自己畫出來
