1、一、创建对话框应用程序二、编辑对话框资源控件 ID及标题IDC_LIST1IDC_GETNEIGHBOR 获取网上邻居三、添加变量、函数1、添加变量2、添加消息响应函数3、添加类成员函数四、添加代码BOOL CGetNeighborDlg:Enumerate(LPNETRESOURCE lpNetRC_p, int depth)HANDLE hEnum = 0;DWORD dwScope = RESOURCE_GLOBALNET ;DWORD dwType = RESOURCETYPE_ANY ;DWORD dwResult = WNetOpenEnum(dwScope, / scope of

6、t.RemoveAll();m_NeighborList.RemoveAll(); 五、添加对象/库模块 点“工程”，点“设置”，点选“连接”，添加“MPR.LIB ws2_32.lib.”模块。六、编译七、运行七、函数说明1、WNetOpenEnum 函数声明DWORD WNetOpenEnum(DWORD dwScope,DWORD dwType,DWORD dwUsage,LPNETRESOURCE lpNetResource,LPHANDKE lphEnum)dwScope：指定列举范围。dwType：指定列举资源类型。dwUsage：指定列举资源用法。第一个参数 dwScope为RE
7、SOURCE_GLOBALNET，则该参数被勿略。lpNetResource：指向包含列举资源相关信息之 NETRESOURCE结构的指针。lphEnum：指向列举变量之句柄指针，为调用 WNetEnumResource()函数做准备。功能：开始一网络资源或存在的网络连接枚举值。成功则返回非零值；失败则返回 FALSE。2、WNetEnumResource 函数声明DWORD WNetEnumResource(HANDLE hEnum,LPDWORD lpcCount,LPVOID lpBuffer,LPDWORD lpBufferSize)hEnum：WNetOpenEnum()函数返回的标
8、识某枚举实例之句柄。lpcCount：指定枚举条目数量。lpBuffer：指向取得枚举结果之缓冲区指针，用 NETRESOURCE结构数组表示。lpBufferSize：指定上述缓冲区大小。功能：获取详细网络资源信息。3、NETRESOURCE 结构定义typedef struct_NETRESOURCEDWORD dwScope; /指定列举范围DWORD dwType; /指定列举资源类型DWORD dwDisplayType; /表示网络浏览用户接口显示该网络实体之方式DWORD dwUsage; /指定列举资源用法DWORD dwScopeLocalname;DWORD dwRemoteName; /指向网络中远程计算机名DWORD dwComment;DWORD dwPrivider;NETRESOURCE4、WNetCloseEnum 函数声明DWORD WNetCloseEnum(HANDLE hEnum)hEnum：WNetCloseEnum()函数建造的枚举句柄。功能：结束网络资源枚举。成功则返回非零值；失败则返回FALSE。
