在c程序中启动和停止服务

以下是代码片段：
__declspec(dllexport)
void RemoveService(
   HWND hwnd,       // handle to owner window
   HINSTANCE hinst,  // instance handle for the DLL
   LPTSTR lpCmdLine, // string the DLL will parse
   int nCmdShow    // show state
   )
{
// Open a handle to the SC Manager database.
SC_HANDLE schSCManager = NULL, schService = NULL;

//create service
schSCManager = OpenSCManager(NULL, NULL, SC_MANAGER_ALL_ACCESS);
if (schSCManager == NULL) goto cleanup;

schService = OpenService(
schSCManager,    // SCManager database
TEXT(svcname), // name of service
DELETE);
if (schService == NULL) goto cleanup;

CloseServiceHandle(schSCManager);

//启动服务
if (! DeleteService(schService) ) goto cleanup;
//MessageBox(NULL, "Removed!!", "OK", MB_OK);

cleanup:
hsError = GetLastError();
CloseServiceHandle(schService);
}

__declspec(dllexport)
void InstallService(
   HWND hwnd,       // handle to owner window
   HINSTANCE hinst,  // instance handle for the DLL

   int nCmdShow    // show state
   )
{
// Open a handle to the SC Manager database.

cleanup:
