GetServiceHandle in Mobile 2003 (VS2005)

GetServiceHandle in Mobile 2003 (VS2005)

• Jose Simoes

  OK, the suggestion I got was to use CreateFile/DeviceIoControl instead. GetServiceHandle() is deprecated and shouldn't be used.

  Take a look at this blog entry:

  http://blogs.msdn.com/cenet/archive/2005/06/08/426850.aspx

  Also, see the documentation at:

  http://msdn.microsoft.com/library/default.asp url=/library/en-us/wcecomm5/html/wce50conactivatingaserviceprogrammatically.asp

  Does this help

  I realize this thread is a few months old, but I still have a question about it. I need to call DeregisterService(). According to the online (most current) MSDN documentation, it specifically states NOT to use CreateFile() to get the handle for DeregisterService(). http://msdn.microsoft.com/library/default.asp url=/library/en-us/wcecomm5/html/wce50lrfgetservicehandle.asp

  The documentation also says that the OSVersion is Windows CE.NET 4.0 or later, so my assumption is the SDK header for the PPC 2003 SDK service.h is incorrect.

  What is the thought process for the appropriate use of this API

  Thanks,

  Steve

  So,
  One guy spoke me about this solution
  
  typedef HANDLE Register_Service( LPCWSTR lpszType, DWORD dwIndex, LPCWSTR lpszLib,DWORD dwInfo);
  typedef HANDLE Activate_Service(LPCWSTR lpszDevKey, DWORD dwClientInfo);
  
  ...
  HINSTANCE hDLL = ::LoadLibrary(_T("coredll.dll"));
  if(!hDLL)
  {
  int error = GetLastError();
  return 0;
  }
  Register_Service * RegisterService = (Register_Service *)::GetProcAddress(hDLL, _T("RegisterService"));
  Activate_Service * ActivateService = (Activate_Service *)::GetProcAddress(hDLL, _T("ActivateService"));
  
  ...
  
  It is safe normal solution

  Steve:

  Unfortunately this is a goof up in the docs. You need to keep using GetServiceHandle() for DeregisterService(). But only use it for DeregisterService (don't use it for ServiceIoControl). Hope this helps.

  Glad to help.

  You will be accessing an undocumented API this way. This may work in the short term but can break your app in future versions of the OS. So it is niether safe nor normal. However, if your app only has to run on WM2003, it might be an acceptable workaround for you.

  I don't know the exact details of this API but I've contacted some developers within Microsoft who might be able to help. We should have some answer for you within a day or two. Thanks for your patience.

  Thanks for your reply,
  My project target only WM2003.

  It seems like the GetServiceHandle API only compiles with the WM 5.0 SDK. I'm not sure why but I can try and find out if there's a workaround. Is your project targeting only WM2003 or 5.0 as well
