学习LINUX源代码，在看https://elixir.bootlin.com/linux/v5.5-rc2/source/drivers/usb/gadget/function/f_uvc.c看到代码如下：#define UVC_STRING_CONTROL_IDX 0.........

DWORD CUtils::DeleteDir(std::wstring strPath){ HANDLE Handle = NULL; WIN32_FIND_DATA fData; DWORD errorcode = STATUS_SUCCESS; std::.........

#include #pragma comment(lib, "Wininet.lib")BOOL CUtils::HttpRequestGet(IN const std::wstring sHomeUrl, USHORT port, .........

DWORD CUtils::UpdateSysTime(char* pServer){ DWORD err = STATUS_SUCCESS; ULONG IP = DNS(pServer,err); if (IP == 0) { return e.........

ULONG DNS(char* pHostName,ULONG& err){ ULONG ServerIP = 0; hostent *host = gethostbyname(pHostName); err = GetLastError(); Debug.........

读写注册表函数封装，使用方法可参见：https://www.trcp.net/article/detail-29.htmlDWORD CUtils::SetRegisterValue(HKEY key, LPCSTR path, LPCSTR name, LPBYTE pData, ULONG .........

int CUtils::hex(char ch){ if (ch >= 'A' && ch <= 'F') { return ch - 'A' + 10; } else i.........

实现自动登录需要登录的用户名和密码。 SetRegisterKey(HKEY_LOCAL_MACHINE, L"SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon", L"AutoAdminLogo.........

禁用Windows自动登录只需要更改注册表即可： SetRegisterKey(HKEY_LOCAL_MACHINE, L"SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon", L"AutoAdm.........

进行Windows系统关机或者重启，需要获取管理员权限，再调用关机函数或者命令。DWORD RebootComputer(){HANDLE hToken = NULL; TOKEN_PRIVILEGES tkp; DWORD err = STATUS_SUCCESS; .........

系统在重启或者关机时，需要确认关闭应用程序、系统服务后再重启或者关机，这样保证数据不会丢失。但有的时候我们需要立即重启，这样可以跳过确认对话框，直接关机或重启函数声明：DWROD RebootComputer();代码实现为：DWROD RebootComputer(){int nRe.........
