090826项目进展：添加smb资源的网段搜索二

 

1，添加变量

// Dialog Data
 //{{AFX_DATA(CDlgSmbList)
 enum { IDD = IDD_SMBLIST };
 CTreeCtrl m_smbTree;
 CIPAddressCtrl m_addrTo;
 CIPAddressCtrl m_addrFrom;
 //}}AFX_DATA

 

2，函数OnButtonSearch

void CDlgSmbList::OnButtonSearch()
{
 // TODO: Add your control notification handler code here
 UpdateData(TRUE);

 tListSmb.pm_addrFrom = &m_addrFrom;
 tListSmb.pm_addrTo = &m_addrTo;
    tListSmb.pm_smbTree = &m_smbTree;

    m_smbTree.DeleteAllItems();
    AfxBeginThread(ThreadFuncListSmbRecource, &tListSmb);
}

 

3，使用线程函数

a，先判断某一ip是否在线

b，如果在线采取获取共享资源

UINT ThreadFuncListSmbRecource(LPVOID lpParam) { tCheckStatus* pInfo=(tCheckStatus*)lpParam; BYTE field0,field1,field2,field3; BYTE field4,field5,field6,field7; pInfo->pm_addrFrom->GetAddress(field0,field1,field2,field3); pInfo->pm_addrTo->GetAddress(field4,field5,field6,field7); CString strIPAddr; for(int i =field3; i <= field7; i++) { strIPAddr.Format("%d.%d.%d.%d",field0,field1,field2,i); pInfo->pm_wndMessage->SetWindowText(""+strIPAddr); if(CheckHostStatus(strIPAddr)) { ListOnlineRecourse(pInfo->pm_smbTree, strIPAddr); } } return 0; }

 

void ListOnlineRecourse(CTreeCtrl* pTree, const CString &strIP) { /* 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; HTREEITEM hItemParent = pTree->InsertItem(strIP, 0, 1); CString cstrTemp = "" + strIP; 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); pTree->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; } }
