Remember that on Vista/Win7 then services are running in their own session. When starting the UI application then it must be running in the user-session.

Have feeling that it is better that it is user that starts the UI application (Maybe as a process started at user-login). The UI can then contact the service through whatever communication form you like. Namedpipes might be a good way.

How does the worker thread fills the list (I hope it just sends meesages and leave the UI updating task to the UI thread...)?

No surprise there. The worker thread should not be interacting with any UI control that it does not own. It should use PostMessage() instead.

How to get ShutdownBlockReasonCreate for windows vista?

Hello,
I had made an application which trapped WM_QUERYSESSION to block SHUTDOWN and LOGOFF in Windows XP. When Trying to port this solution on VISTA/WINDOWS 2008/Windows 7 I need to call additional methods namely ShutdownBlockReasonCreate() , ShutdownBlockReasonDestroy() which is defined in winuser.h for VISTA. After installing VS 2005 and upgrading it for windows VISTA by SP1 , I am still not getting ShutdownBlockReasonCreate () in windows vista winuser.h. Please let me know where am I doing things wrong .

Regards,
Kushagra

I hate coding but I luv to develop Smile | :)

In the *.cpp files where you call these functions paste somewhere at the beginning (but after #include stdafx.h):

BOOL WINAPI ShutdownBlockReasonDestroy(
  __in  HWND hWnd
);

BOOL WINAPI ShutdownBlockReasonCreate(
  __in  HWND hWnd,
  __in  LPCWSTR pwszReason
);

Download and install the latest Windows SDK from Windows SDK for Windows Server 2008 and .NET Framework 3.5[^].

Then run the Windows SDK Configuration Tool from Start -> All Programs -> Microsoft Windows SDK v6.1 -> Visual Studio Registration to integrate it with Visual Stdio.

Hi All
I've a doubt. when should we use a vector, when to use list and when we should go for map container in our programming?

Thank you all.

It's easy to differentiate the use of the three containers you mentioned in your query. Just read the documentation for the containers in MSDN

You need to google first, if you have "It's urgent please" mentioned in your question.

If you need random access operation frequently in your code, use vector.
If you need insert and delete operation frequently, use list.
And map should be use when you want to identify a value by a key(mobbish).

Win Service is not accessing desktop application

I have written windows service in C++ using winsvc.h.

Registering the exe to run as service.

Service runs under "SYSTEM" credentials and it starts at system startup.

Using this service I can able to access processes only which are running under "SYSTEM".

Is there any property or method related to service in WinSvc.h while creating or starting service, which is used to set the service to access any process running on the desktop.

I can set this manually in services.msc for particular service under log on tab in properties.

But want to set it programmatically.

I tried checking many blogs and googled but there is no clue.

Please give me clue.

Thanks in advance.

Regards,
Gtag.
