MFC中使用SDK个人经验总结(包含海康威视云台相机)

dlgdata.cpp Line 40 的问题

首先打开C->PROGRAM FILE(X86)->Microsoft Visual Studio 11.0->VC->atlmfc->src->mfc->dlgdata.cpp打开，并在LINE40添加断点，调试找出nIDC的值，然后解决问题！

如果在resource.h中找不到对应ID，又或者更改过resource.h，出现异常，应删除debug 文件夹，重新生成解决方案！！！重新生成！

1.项目属性中“C/C++”->“常规”->“附加包含目录”添加SDK包中的头文件；

2.项目属性中“链接器”->“常规”->“附加库目录”把对应的文件夹位置添加进去；

3.项目属性中“链接器”->"输入"->“附加依赖项”添加相应的lib文件名。

4.在C***Dlg.h中添加头文件#include"GeneralDef.h"

5.在C***App的初始化程序InitInstance()中添加SDK的初始化程序NET_DVR_Init();

6.添加成员变量：播放句柄变量LONG m_lPlayHandle; 播放句柄用于判断是否播放正常以及作为NET_DVR_StopRealPlay等函数的句柄参数。

添加成员变量

DWORD m_fault_code;

BOOL m_bIsLogin;

BOOL m_bIsPlaying;

STRU_DEVICE_INFO m_struDeviceInfo;

并在构造函数中对其初始化

m_lPlayHandle = -1;

m_fault_code = 0;

m_bIsLogin = FALSE;

m_bIsPlaying = FALSE;

7.在C***Dlg.cpp中添加全局变量

char DeviceIp[13] = "192.168.1.11";

char UserName[6] = "admin";

char Password[10] = "xde123456";

WORD DeviceIpPort = 8000;

8.单按钮启动

if(!m_bIsLogin)

{

NET_DVR_DEVICEINFO_V30 DeviceInfoTmp;

memset(&DeviceInfoTmp,0,sizeof(NET_DVR_DEVICEINFO_V30));

LONG lLoginID = NET_DVR_Login_V30(DeviceIp , DeviceIpPort, UserName, Password,

&DeviceInfoTmp);

if(lLoginID == -1)

{

CString strTemp;

strTemp.LoadStringW(IDS_STRING_0_LOGIN_STATUS);

MessageBox(strTemp);

return;

}

m_bIsLogin = TRUE;

m_struDeviceInfo.lLoginID = lLoginID;

m_struDeviceInfo.iDeviceChanNum = DeviceInfoTmp.byChanNum;

m_struDeviceInfo.iIPChanNum = DeviceInfoTmp.byIPChanNum;

m_struDeviceInfo.iStartChan = DeviceInfoTmp.byStartChan;

m_struDeviceInfo.iIPStartChan = DeviceInfoTmp.byStartDChan;

}

if(!m_bIsPlaying)

{

NET_DVR_PREVIEWINFO ClientInfo = {0};

ClientInfo.lChannel = 1;

//选择预览的窗口句柄

ClientInfo.hPlayWnd = GetDlgItem(IDC_0_STATIC_CAMERA)->m_hWnd;

m_lPlayHandle = NET_DVR_RealPlay_V40(m_struDeviceInfo.lLoginID, &ClientInfo, NULL, NULL);

//预览播放成功返回非负数，失败返回-1

if(m_lPlayHandle >= 0)

{

m_bIsPlaying = TRUE;

CString strTemp;

strTemp.LoadStringW(IDS_STRING_0_PLAY_BUTTON_STATUS2);

GetDlgItem(IDC_0_PLAY)->SetWindowText(strTemp);

this->SetTimer(Timer_Camera_Connect_Detection, 1000, NULL);

}

else

{

CString strTemp1;

strTemp1.LoadStringW(IDS_STRING_0_PLAY_STATUS);

CString strTemp2;

m_fault_code = NET_DVR_GetLastError();

strTemp2.Format(L"%d", m_fault_code);

CString strTemp3;

strTemp3.LoadStringW(IDS_STRING_0_PLAY_FAULT_CODE);

CString strTemp4;

strTemp4 = strTemp1 + L", " + strTemp3 + strTemp2;

MessageBox(strTemp4);

return;

}

}

else

{

m_bIsPlaying = FALSE;

CString strTemp;

strTemp.LoadStringW(IDS_STRING_0_PLAY_BUTTON_STATUS1);

GetDlgItem(IDC_0_PLAY)->SetWindowText(strTemp);

NET_DVR_StopRealPlay(m_lPlayHandle);

m_lPlayHandle = -1;

GetDlgItem(IDC_0_STATIC_CAMERA)->Invalidate();

}

云台控制

1.添加一个基于CButton的CPTZButton类，

2.在头文件中添加以下声明

#if !defined(AFX_PTZBUTTON_H__B3E99438_BBCE_4862_845F_D3AB668824A6__INCLUDED_) #define AFX_PTZBUTTON_H__B3E99438_BBCE_4862_845F_D3AB668824A6__INCLUDED_

#if_MSC_VER > 1000

#pragma once

#endif// _MSC_VER > 1000

并在头文件的结尾加上#endif

3.添加成员变量

int m_iSubBtnIndex; //功能按钮的索引号，添加按钮类时自动+1，用于对应相应功能

添加成员函数

void PTZControlAll(LONG lRealHandle,DWORD dwPTZCommand,DWORD dwStop ,int Speed); //用于实现各按钮的功能

4.添加全局变量int g_iPtzBtnIndex = 0;

在构造函数中对m_iSubBtnIndex进行初始化m_iSubBtnIndex = g_iPtzBtnIndex++;

5.通过类向导，添加消息处理函数OnLButtonDown和OnLButtonUp；

6.在PTZButton.cpp中添加***app的头文件，并添加声明

#ifdef_DEBUG

#define new DEBUG_NEW

#undef THIS_FILE

static char THIS_FILE[] = __FILE__;

#endif

7.在按钮所在画面的类中添加两个函数，用于获得预览窗口的句柄以及云台移动的速度。

LONG CFrameCameraControl::GetPlayHandle()

{

return m_lPlayHandle;

}

int CFrameCameraControl::GetPTZSpeed()

{

return 2;

}

8. 获得按钮所在画面的句柄，用来调用前面的两个函数。

在APP的.h和.cpp文件中添加全局变量CFrameCameraControl *g_pFrame_Camera_Control = NULL;

然后在dlg.cpp中创建画面后，把按钮所在画面的句柄赋值给g_pFrame_Camera_Control。

9. void CPTZButton::OnLButtonDown(UINT nFlags, CPoint point)

{

// TODO: 在此添加消息处理程序代码和/或调用默认值

LONG lPlayHandle = g_pFrame_Camera_Control->GetPlayHandle();

int iPTZSpeed = g_pFrame_Camera_Control->GetPTZSpeed();

switch(m_iSubBtnIndex)

{

case 0: //云台上

PTZControlAll(lPlayHandle,TILT_UP,0,iPTZSpeed);

break;

case 1: //云台下

PTZControlAll(lPlayHandle,TILT_DOWN,0,iPTZSpeed);

break;

case 2: //云台左

PTZControlAll(lPlayHandle,PAN_LEFT,0,iPTZSpeed);

break;

case 3: //云台右

PTZControlAll(lPlayHandle,PAN_RIGHT,0,iPTZSpeed);

case 4: //调焦左

PTZControlAll(lPlayHandle,ZOOM_IN,0,iPTZSpeed);

case 5: //调焦右

PTZControlAll(lPlayHandle,ZOOM_OUT,0,iPTZSpeed);

break;

case 6: //聚焦左

PTZControlAll(lPlayHandle,FOCUS_NEAR,0,iPTZSpeed);

break;

case 7: //聚焦右

PTZControlAll(lPlayHandle,FOCUS_FAR,0,iPTZSpeed);

break;

case 8: //光圈左

PTZControlAll(lPlayHandle,DOWN_LEFT,0,iPTZSpeed);

CButton::OnLButtonDown(nFlags, point);

}

void CPTZButton::OnLButtonUp(UINT nFlags, CPoint point)

void CPTZButton::PTZControlAll(LONG lRealHandle,DWORD dwPTZCommand,DWORD dwStop ,int Speed)

{

if(lRealHandle>=0)

BOOL ret = FALSE;

if(Speed>=1)

AfxMessageBox(L"云台控制失败!");

}

}

10 按钮所在画面中添加按钮成员变量，变量类型为CPTZButton，注意，这里按钮添加的顺序应安装CPTZButton类中switch的顺序添加。
