vba 监控删除 怎么删除监控文件

文件监控之查找/删除/下载/上传

这两节主要实现四个功能：文件查找，删除，下载，上传。

这节主要做客户端：

FileSpy类:

1.首先创建一个FileSpy类。

2.遍历目录/文件夹函数：

std::vector<std::string> FileSpy::getDirs(std::string dir)
{
    WIN32_FIND_DATAA findData;
    HANDLE hFind = FindFirstFileA(dir.append("\\*").data(), &findData);
    std::vector<std::string> files;


    if (hFind == INVALID_HANDLE_VALUE) {
        return files;
    }


    // 遍历目录来获取路径
    while (FindNextFileA(hFind, &findData)) {
        // 不需要后退和当前目录
        if(!strcmp(findData.cFileName,"..") || !strcmp(findData.cFileName,".")) {
            continue;
        }


        // 判断路径
        if (findData.dwFileAttributes & FILE_ATTRIBUTE_DIRECTORY) {
            files.push_back(findData.cFileName);
        }
    }


    // 释放句柄
    CloseHandle(hFind);


    return files;
}

std::vector<std::string> FileSpy::getFiles(std::string dir)
{
    WIN32_FIND_DATAA findData;
    HANDLE hFind = FindFirstFileA(dir.append("\\*").data(), &findData);
    std::vector<std::string> files;


    if (hFind == INVALID_HANDLE_VALUE) {
        return files;
    }


    // 遍历目录来获取文件
    while (FindNextFileA(hFind, &findData)) {
        // 不需要后退和当前目录
        if(!strcmp(findData.cFileName,"..") || !strcmp(findData.cFileName,".")) {
            continue;
        }


        // 判断不是路径
        if (!(findData.dwFileAttributes & FILE_ATTRIBUTE_DIRECTORY)) {
            files.push_back(findData.cFileName);
        }
    }


    // 释放句柄
    CloseHandle(hFind);


    return files;
}

3.查找所有盘符，比如:C盘，D盘:

std::vector<std::string> FileSpy::getDrives()
{
    std::vector<std::string> drives;


    // 遍历a-z盘符
    for (int i='b'; i<='z'; i++) {
        char d[MAX_PATH];
        sprintf(d, "%c:\\*", i);


        WIN32_FIND_DATAA findData;
        HANDLE h = FindFirstFileA(d, &findData);
        if (h != INVALID_HANDLE_VALUE) {
            d[strlen(d)-1] = '\0';
            drives.push_back(d);


            // 释放句柄
            CloseHandle(h);
        }
    }


    return drives;
}

4.至于网络方面都和上一节没什么区别。

代码修改：

1.更改TcpSocket类sendData函数:

bool TcpSocket::sendData(const char *data,unsigned int size)
{
    if ((int)mSock == SOCKET_ERROR) {
        std::cout << "Socket do not allowed to send data without connected " << std::endl;
        std::fflush(stdout);;
        return false;
    }


    int ret = SOCKET_ERROR;
    const unsigned int packetLen = 800;
    // 小于pakcetLen的话，就直接发送，不然就分包发送
    if (size <= packetLen) {
        ret = send(mSock, data, size, 0);


        // 出现错误，断开连接
        if (ret == SOCKET_ERROR) {
            std::cout <<  "Failed to send data to " <<  mIp << std::endl;
            std::fflush(stdout);;
            dissconnect();
        }
    } else {
        unsigned int pos = 0;
        while (pos < size) {
            unsigned int sendSize = pos+packetLen > size ? size-pos : packetLen;


            // 发送
            ret = send(mSock, data+pos, sendSize, 0);


            // 出现错误，断开连接
            if (ret == SOCKET_ERROR) {
                std::cout <<  "Failed to send data to " <<  mIp << std::endl;
                std::fflush(stdout);;
                dissconnect();
                break;
            }


            pos += packetLen;
        }
    }


    return ret != SOCKET_ERROR ? true : false;
}

我上代码了:
