C++写注册表项实例

void SelfRun(LPSTR lpszValueName) //lpszValueName 显示的名称 
{ 
    LPCTSTR lpSubKey = "Software\\Microsoft\\Windows\\CurrentVersion\\Run"; 
    HKEY hKey; 
    DWORD dwDisposition = REG_OPENED_EXISTING_KEY; 
    //打开注册表项 
    LONG lRet = ::RegCreateKeyEx(HKEY_LOCAL_MACHINE, lpSubKey, NULL, NULL, REG_OPTION_NON_VOLATILE,KEY_ALL_ACCESS, NULL, &hKey, &dwDisposition); 
    //LONG lRet = ::RegCreateKeyA(HKEY_LOCAL_MACHINE, lpSubKey, &hKey); 
    if ( ERROR_SUCCESS != lRet) 
    { 
        return; 
    } 
    char szModuleName[MAX_PATH]={0}; 
    ::GetModuleFileNameA(NULL, szModuleName, MAX_PATH); //得到当前程序路径 
 
    lRet = ::RegSetValueEx(hKey, lpszValueName, NULL, REG_SZ, (BYTE*)szModuleName, strlen(szModuleName)+1); //设置注册表项 
    if ( ERROR_SUCCESS != lRet) 
    {

}

    SelfRun("runModel"); 
    return 0;
