VC6.0视频采集的步骤：  
1、插入摄像头，安装驱动  VCap2800  USB2.0 DRV（windows 7）或者Vcap2820 sdk，两者依次尝试

![Center 1][]

![Center 2][]

![Center 3][]

![Center 4][]

注意：驱动有一下几种，如果USB2.0 DRVB不成功！！可以换驱动VCap2820 sdk进行尝试!!!

![Center 5][]

![Center 6][]

2、G:\\VC++视频采集资料\\USB2800\\Vcap2820 sdk\\Vcap2820 sdk目录下的    devwdm.ax   放到c:\\windows\\system32\\目录下

![Center 7][]

3、打开 “运行”，输入   Regsvr32  c:\\windows\\system32\\devwdm.ax   进行注册驱动

![Center 9][]

4、创建VC工程，基于对话框

![Center 10][]

![Center 11][]

![Center 12][]

![Center 13][]

5、添加devwdm.dll  devwdm.h  devwdm.lib到项目中，这些是摄像头的相关API

![Center 14][]  
5、在StdAfx.h文件中加载动态链接库  
      \#pragma comment(lib,"devwdm.lib")

// stdafx.h : include file for standard system include files,
    //  or project specific include files that are used frequently, but
    //      are changed infrequently
    //
    
    #if !defined(AFX_STDAFX_H__1357FC0D_0191_4DD3_8CB5_4A15DA0B970C__INCLUDED_)
    #define AFX_STDAFX_H__1357FC0D_0191_4DD3_8CB5_4A15DA0B970C__INCLUDED_
    
    #if _MSC_VER > 1000
    #pragma once
    #endif // _MSC_VER > 1000
    
    #define VC_EXTRALEAN		// Exclude rarely-used stuff from Windows headers
    
    #include <afxwin.h>         // MFC core and standard components
    #include <afxext.h>         // MFC extensions
    #include <afxdisp.h>        // MFC Automation classes
    #include <afxdtctl.h>		// MFC support for Internet Explorer 4 Common Controls
    #ifndef _AFX_NO_AFXCMN_SUPPORT
    #include <afxcmn.h>			// MFC support for Windows Common Controls
    #endif // _AFX_NO_AFXCMN_SUPPORT
    
    //注册动态链接库
    #pragma comment(lib,"devwdm.lib")
    
    //{
       {AFX_INSERT_LOCATION}}
    // Microsoft Visual C++ will insert additional declarations immediately before the previous line.
    
    #endif // !defined(AFX_STDAFX_H__1357FC0D_0191_4DD3_8CB5_4A15DA0B970C__INCLUDED_)

6、添加头文件到响应的cpp应用文件中，进行测试

#include "devwdm.h"

void CVideoDemoDlg::OnOK() 
    {
    	// TODO: Add extra validation here
    
    	devwdm_InitCard(0,m_static.m_hWnd,300,400);//初始化
    
        devwdm_StartVideoPreview(0);//启动
    	
    //	CDialog::OnOK();
    }
