最近有些忙碌，今天终于有时间和大家聊一聊“万能驱动摄像头sz339l”的话题。如果你对这个领域还比较陌生，那么这篇文章就是为你而写的，让我们一起来了解一下吧。
1.怎么用万能摄像头驱动程序安装“百脑通SZ339L”的摄像头？（要包成功）
2.VB摄像头硬件拍照功能实现
3.用C#如何实现启动摄像头?
4.C#中如何用摄像头拍照
怎么用万能摄像头驱动程序安装“百脑通SZ339L”的摄像头？（要包成功）
第一步：先在桌面上新建一个文件夹，重新命名，比如PCCAMERA,将你的万能驱动压缩包，解压到这个文件夹。注意是所有文件。第二步：插上摄像头，右键点击我的电脑-属性-硬件-设备管理器，看到一个**带问号的PCcamera,右键-更新驱动程序，然后将路径指到桌面上的PCCAMERA文件夹，确定。会出现安装过程，一路确定。第三步：打开这个文件夹，你会看到AMCAP这个程序，双击，看见你自己了吗？ 至于这个文件夹你现在可以放到任何盘任何地方了
VB摄像头硬件拍照功能实现

如果找不到的话，可以下载个驱动精灵。一切搞定
你也可以下载个万能摄像头驱动，用下面的方法安装试试：

如果还不行，试试下载安装个驱动人生活着驱动魔法师后，应该可以找到的
用C#如何实现启动摄像头?
并不是你的问题没人会回答。而是你提问的地方不对，你这个属于硬件编程了，放到软件编程里当然没几个人会回答啦，下面是一个实例，直接点击摄像头上的拍照按钮的。Private Sub Form_Load()
