090809项目进展

 

今天尽量完成：

一，公网socket时，CheckServerStatus的返回值总是TRUE，换成pSession->GetFtpConnection检测看看；

BOOL CheckServerStatus(CString &strIPAddr, UINT uiPort){//SOCKET cmdSocket;//struct sockaddr_in hostaddr;//int ret = 0;CInternetSession *pSession = NULL;CFtpConnection *pConnection= NULL;char destip[20] ;sprintf(destip, "%s", strIPAddr.GetBuffer(strIPAddr.GetLength()));pSession=newCInternetSession(AfxGetAppName(),1,PRE_CONFIG_INTERNET_ACCESS);try{pConnection=pSession->GetFtpConnection(destip, "anonymous", "anonymous", uiPort, TRUE);}catch(CInternetException*e){pConnection=NULL;e->Delete();} if(pConnection!=NULL){ pConnection->Close(); delete pSession;returnTRUE;} else { return FALSE; }//char destip[20] ;//sprintf(destip, "%s", strIPAddr.GetBuffer(strIPAddr.GetLength()));////hostaddr.sin_family = AF_INET;//hostaddr.sin_port = (unsigned short)htons(uiPort);//hostaddr.sin_addr.s_addr = inet_addr(destip);////cmdSocket = socket(AF_INET,SOCK_STREAM, IPPROTO_TCP);////ret = connect(cmdSocket, (const struct sockaddr*)&hostaddr, sizeof(hostaddr));//if(ret != 0)//{//return FALSE;//}}

 

运行正常，结果准确。

 

二，公网一个FTP：58.192.112.14，连接速度还不错，使用CTreeCtrl把 文件名 的树形结构画出来。

 

第一步：不进行深度遍历，只使用CTreeCtrl显示 根目录“/” 下的所有文件名。

 涉及到CFtpFileFind的使用：

1，关联

pFileFind = new CFtpFileFind(pConnection);

2，设置目录

pConnection->SetCurrentDirectory(m_Directory);

3，查找，结果放在pFileFind的成员list，msdn还没下好，暂时明确不了是怎样继承而来的一个结构。

IsContinue = pFileFind->FindFile("*");

4，取文件名

m_FileName = pFileFind->GetFileName();

5，定位到下一个文件

IsContinue = pFileFind->FindNextFile();

6，观察当前文件是否为一个“dir”

pFileFind->IsDirectory()

void CListContent::DownLoadContent(){BOOL IsContinue = FALSE;CString strLen = "0";if(m_IsConnected) {pFileFind=newCFtpFileFind(pConnection);m_wndMsg.SetWindowText(m_Directory);if(!pConnection->SetCurrentDirectory(m_Directory)){pFileFind->Close();deletepFileFind;pFileFind = NULL;return ;}IsContinue=pFileFind->FindFile("*");//m_listContent.DeleteAllItems(); m_fileTree.DeleteAllItems(); /* 确定根目录 */ HTREEITEM hItem1A = m_fileTree.InsertItem(m_Directory, 0, 1);while(IsContinue){ /* 同层次的list */IsContinue=pFileFind->FindNextFile();m_FileName=pFileFind->GetFileName();if(pFileFind->IsDirectory()){//inti = m_listContent.InsertItem(0,m_FileName);//m_listContent.SetItemText(i,1,"Directory");//m_listContent.SetItemText(i,2,m_FtpSite); HTREEITEM hItem2_1B = m_fileTree.InsertItem(m_FileName,0,1,hItem1A,TVI_LAST);}else{//inti = m_listContent.InsertItem(0,m_FileName);//strLen.Format("%d",pFileFind->GetLength());//m_listContent.SetItemText(i,1,strLen);//m_listContent.SetItemText(i,2,m_FtpSite); m_fileTree.InsertItem(m_FileName,0,1,hItem1A,TVI_LAST);}}if(m_Directory!="/"){//inti=m_listContent.InsertItem(0,"..");//m_listContent.SetItemText(i,1,"Parent");}pFileFind->Close();deletepFileFind;pFileFind = NULL;}}

 

第二步：使用DPS遍历所有文件

新写一个函数完成文件的DPS遍历，但是进入第2层目录再FindNextFile时返回总是0，无法找到文件，对比了一下也没发现原因，明天继续看。

void CListContent::DownLoadTreeContent(const HTREEITEM hItem1A, const CString &parentDirName, const CString &dir){BOOL IsContinue = FALSE;CString strLen = "0"; CString dirName(dir); CFtpFileFind *pFileTreeFind = NULL;if(m_IsConnected) {pFileTreeFind=newCFtpFileFind(pConnection);if(!pConnection->SetCurrentDirectory(dirName)){pFileTreeFind->Close();deletepFileTreeFind;pFileTreeFind = NULL;return;}IsContinue=pFileTreeFind->FindFile("*");while(IsContinue){ /* 同层次的list */IsContinue=pFileTreeFind->FindNextFile();m_FileName=pFileTreeFind->GetFileName();if(pFileTreeFind->IsDirectory()){ HTREEITEM hItem2_1B = m_fileTree.InsertItem(m_FileName,0,1,hItem1A,TVI_LAST); if (dirName == "/") { DownLoadTreeContent(hItem2_1B, dirName, dirName + m_FileName + "/"); } else { DownLoadTreeContent(hItem2_1B, dirName, dirName + "/" + m_FileName + "/"); }}else{ m_fileTree.InsertItem(m_FileName,0,1,hItem1A,TVI_LAST);}}pFileTreeFind->Close();deletepFileTreeFind;pFileTreeFind = NULL; pConnection->SetCurrentDirectory(parentDirName);}}
