vb.net 如何调用摄像头或数码相机保存照片
请高手帮忙，小弟有些问题一直不解，如何用摄像头和数码相机获取照片，不同牌子不同型号的摄像头或相机是否可以在一个程序下通用？我在网上找段代码但会出错，不知道是不是因为我的摄像头型号的问题？我用的代码是
Public Class Cam Private Const WM_USER As Integer = &H400 Private Const WS_CHILD As Integer = &H40000000 Private Const WS_VISIBLE As Integer = &H10000000 Private Const WM_CAP_START As Integer = WM_USER Private Const WM_CAP_STOP As Integer = WM_CAP_START + 68 Private Const WM_CAP_DRIVER_CONNECT As Integer = WM_CAP_START + 10 Private Const WM_CAP_DRIVER_DISCONNECT As Integer = WM_CAP_START + 11 Private Const WM_CAP_SAVEDIB As Integer = WM_CAP_START + 25 Private Const WM_CAP_GRAB_FRAME As Integer = WM_CAP_START + 60 Private Const WM_CAP_SEQUENCE As Integer = WM_CAP_START + 62 Private Const WM_CAP_FILE_SET_CAPTURE_FILEA As Integer = WM_CAP_START + 20
