090817项目进展

1，昨天留下一个RadioButton的问题，本来还认为可能需要再去看看MFC消息机制的，忽然想起一个更简单的方法，方便易行，问题解决了。

void CSearchSite::OnRadioSmb()
{
 // TODO: Add your control notification handler code here
 m_port = 0;

    m_serverType = 1; // HERE ：  用来控制 RadioButton 的选择。
    
    UpdateData(FALSE);
}

 

 

2，搜索SMB主机共享的目录结构，并使用CTreeCtrl表示出来。

没改动其他地方，直接在void CListContent::OnGetContent() 中加入使用WNet系列函数获取共享资源的功能。

void CListContent::OnGetContent() { UpdateData(true); m_IPAddrDest.GetWindowText(m_FtpSite); /* FTP */ if (0 == m_serverType) { if(!m_IsConnected) { if(ConnectToServer()) { m_IsConnected = TRUE; m_btnGetContent.SetWindowText("断开连接"); } else { return ; } m_Directory = "/"; /* 原程序 */ // DownLoadContent(); /* DPS */ // m_fileTree.DeleteAllItems(); // /* 确定根目录 */ // HTREEITEM hItem1A = m_fileTree.InsertItem(m_Directory, 0, 1); // DownLoadTreeContent_DPS(hItem1A, m_Directory, m_Directory); /* WPS */ m_fileTree.DeleteAllItems(); DownLoadTreeContent_WPS(3); } else { DisconnectedFromServer(); m_IsConnected = FALSE; m_btnGetContent.SetWindowText("连接主机"); m_fileTree.DeleteAllItems(); } } /* SMB */ else { /* 1，入参初始化，NETRESOURCE初始化 */ DWORD dwResult, dwResultEnum; HANDLE hEnum; DWORD cbBuffer = 16384; // 16K is a good size DWORD cEntries = -1; // enumerate all possible entries LPNETRESOURCE lpnrLocal; // pointer to enumerated structures DWORD i; m_fileTree.DeleteAllItems(); HTREEITEM hItemParent = m_fileTree.InsertItem(m_FtpSite, 0, 1); CString cstrTemp = "" + m_FtpSite; NETRESOURCE tNetRs; memset(&tNetRs, 0, sizeof(NETRESOURCE)); tNetRs.dwScope = RESOURCE_GLOBALNET; tNetRs.dwType = RESOURCETYPE_ANY; tNetRs.dwDisplayType = RESOURCEDISPLAYTYPE_SERVER; tNetRs.dwUsage = RESOURCEUSAGE_CONTAINER; tNetRs.lpProvider = "Microsoft Windows Network"; char destip[64] ; sprintf(destip, "%s", cstrTemp.GetBuffer(cstrTemp.GetLength())); int cntDelete = strlen(destip) + 1; tNetRs.lpRemoteName = destip; NETRESOURCE *lpnr = &tNetRs; // 2，检测主机是否在线 // Call the WNetOpenEnum function to begin the enumeration. dwResult = WNetOpenEnum(RESOURCE_GLOBALNET, // all network resources RESOURCETYPE_ANY, // all resources 0, // enumerate all resources lpnr, // NULL first time the function is called &hEnum); // handle to the resource if (dwResult != NO_ERROR) { return; } // // Call the GlobalAlloc function to allocate resources. lpnrLocal = (LPNETRESOURCE)GlobalAlloc(GPTR, cbBuffer); if (lpnrLocal == NULL) { return; } do { // // Initialize the buffer. // ZeroMemory(lpnrLocal, cbBuffer); // 3，遍历资源，并挂载树结构 // Call the WNetEnumResource function to continue // the enumeration. dwResultEnum = WNetEnumResource(hEnum, // resource handle &cEntries, // defined locally as -1 lpnrLocal, // LPNETRESOURCE &cbBuffer); // buffer size // // If the call succeeds, loop through the structures. if (dwResultEnum == NO_ERROR) { for(i = 0; i < cEntries; i++) { // Call an application-defined function to // display the contents of the NETRESOURCE structures. // DisplayStruct(&lpnrLocal[i]); // 将以前的打印 改进为 挂载树 CString strSmbFile(lpnrLocal[i].lpRemoteName); strSmbFile.Delete(0, cntDelete); m_fileTree.InsertItem(strSmbFile,0,1, hItemParent, TVI_LAST); } } // Process errors. else if (dwResultEnum != ERROR_NO_MORE_ITEMS) { break; } } // // End do. // while(dwResultEnum != ERROR_NO_MORE_ITEMS); // 4，释放资源 // Call the GlobalFree function to free the memory. // GlobalFree((HGLOBAL)lpnrLocal); // // Call WNetCloseEnum to end the enumeration. // dwResult = WNetCloseEnum(hEnum); if(dwResult != NO_ERROR) { // // Process errors. // return; } } }

 

 

3，SMB服务器共享文件目录显示
