Question

我在c ++服务上写，但有错误，不能修复它。

我的服务主要功能

int main (int argc, TCHAR *argv[])
{DWORD f;
    for(int i=0;i<113;i++)
        f = GetLastError();
    servicePath = LPTSTR(argv[0]);
    OutputDebugString(_T("My Sample Service: Main: Entry"));
    //InstallService();
    SERVICE_TABLE_ENTRY ServiceTable[] = 
    {
        {SERVICE_NAME, (LPSERVICE_MAIN_FUNCTION) ServiceMain},
        {NULL, NULL}
    };
//  StartService();
    if(!StartServiceCtrlDispatcher(ServiceTable)) {
         f = GetLastError();
      //addLogMessage("Error: StartServiceCtrlDispatcher");

  } else if( memcmp(argv[argc-1],"install",7)) {
    InstallService();
  } else if( memcmp(argv[argc-1],"remove",6)) {
    RemoveService();
  } else if( memcmp(argv[argc-1],"start",5)) {
    StartService();
  } else if( memcmp(argv[argc-1],"stop",4))  {
    // StopService();
  }
//  StopService();
    OutputDebugString(_TEXT("My Sample Service: Main: Exit"));
    return 0;
}

每次在StartServiceCtrlDispatcher上使用命令行参数（service_path和action）调试我的程序时，每次返回1063错误。 Visual Studio我在Administrator下运行。我写错了代码，请帮忙。

Answer 1

您只能在服务控制管理器启动进程时调用StartServiceCtrlDispatcher，即实际作为服务运行时。从任何其他上下文调用时，您将获得ERROR_FAILED_SERVICE_CONTROLLER_CONNECT（1063）。

从代码的外观来看，如果没有传递命令行参数，你应该只调用StartServiceControlDispatcher，例如

if (argc < 2)
{
  if (!StartServiceCtrlDispatcher(ServiceTable)) 
  {
    f = GetLastError();
  }
} 
else if (strcmp(argv[1], "install")
{
  InstallService();
}

等等。

main（）函数还存在一些其他问题，最值得注意的是：

错误的签名; argv []是char，而不是TCHAR
将argv [0]转换为TCHAR
无理由调用GetLastError的循环，114次
使用memcmp代替strcmp

我没看过ServiceMain（）。

当服务安装在Windows 8或更高版本的64位上时，会调用 StartServiceCtrlDispatcher 方法，该方法将调用Main入口点。但是 StartServiceCtrlDispatcher 方法适用于8位指针。

因此，解决方案是使用函数 StartServiceCtrlDispatcherW ，该函数使用16位指针，例如：

之前：它使用指向 LPTSTR （8位）的指针，这是需要 SERVICE_TABLE_ENTRY 和 StartServiceCtrlDispatcher 的数据类型：< / p>

SERVICE_TABLE_ENTRY DispatchTable[] = {
            { (LPTSTR)srvName.str().c_str(), (LPSERVICE_MAIN_FUNCTION)ServiceMain },
            { NULL,NULL }
        };
StartServiceCtrlDispatcher(DispatchTable);

之后：它使用指向 LPWSTR （16位）的指针，这是需要 SERVICE_TABLE_ENTRYW 和 StartServiceCtrlDispatcherW 的数据类型：< / p>

SERVICE_TABLE_ENTRYW DispatchTable[] = {
            { (LPWSTR)srvName.str().c_str(), (LPSERVICE_MAIN_FUNCTION)ServiceMain },
            { NULL,NULL }
        };
StartServiceCtrlDispatcherW(DispatchTable);

结论：

使用宽字符串（每个字符16位）和StartServiceCtrlDispatcherW和SERVICE_TABLE_ENTRYW Type的函数，而不是StartServiceCtrlDispatcher和SERVICE_TABLE_ENTRY。

StartServiceCtrlDispatcher不能访问1063错误
