Beside the solution provided by the poster before, here is an alternative idea.
Catch the SERVICE_CONTROL_SESSIONCHANGE event in your service (only with HandlerEx possible).
This event is triggered every time a user logs on / logs off / remote log on / remote log off etc.
Combined with the solution before you will be able to start your app at the log off of the last user and
stops or pauses if an user logs in.

NetWkstaUserEnum
The NetWkstaUserEnum function lists information about all users currently logged on to the workstation. This list includes interactive, service and batch logons.
I want only the list of interactive users and not service and batch logons , can you please let me know the way to do it ???

Maybe try for every logged-in-user you enumurate NetUserGetInfo with level 23 where flag is UF_NORMAL_ACCOUNT.
|
|
|
|
|
How is that suppose to work? Nearly all user accounts are UF_NORMAL_ACCOUNT regardless of session ID.

Sorry but I just hoped that this will work. I hadn't the time to test.
But as I saw you had an better idea I hope that works.
Regardless of this, I also would think about the idea I posted at first.

Can you explain this with an example ? My goal is simple I want to count the number of active sessions on a server or machine which will be my own base machine , if count comes 0 I will execute my script else I wont.

Finally figured it how it has to be done :
Posting my anwer here :
#include <windows.h>
#include <stdio.h>
// The following constant may be defined by including NtStatus.h.
#define STATUS_SUCCESS ((NTSTATUS)0x00000000L)
// The LSA authentication functions are available in Unicode only.
#define UNICODE
int _cdecl main()
{
PLUID sessions;
ULONG count;
NTSTATUS retval;
int i;
retval = LsaEnumerateLogonSessions(&count, &sessions);
if (retval != STATUS_SUCCESS) {
wprintf (L"LsaEnumerate failed %lu\n",
LsaNtStatusToWinError(retval));
return 1;
}
wprintf (L"Enumerate sessions received %lu sessions.\n", count);
// Process the array of session LUIDs...
for (i =0;i < (int) count; i++) {
GetSessionData (&sessions[i]);
}
// Free the array of session LUIDs allocated by the LSA.
LsaFreeReturnBuffer(sessions);
return 0;
}
it works ffine...SOme body please mark this answer and close the threda as I cant

Hi Experts,
Is there any windows C++ functions which can be used to get the
folder or file name that is selected either by right or left
click.
Got some hints in the forum but that only prints the type of mouse
event like eg Left click or right click. It uses "UserActivityHook"
to know the typeof event. What I would like to know is the file or
folder name on which the mouse is clicked.
Thanks.

You may have to work this out for yourself. When the mouse event fires the screen position of the mouse is captured. You then take that position (x, y), convert it if necessary to be relative to your own window, and figure out which item it is pointing to. If you are using ListView, TreeView etc then there are other events where this conversion is done for you and the actual subitem reference is returned.

Just refer the Shell APIs for those notification refer ChangeNotifiyWatcher.zip in the below link. [^]

Are you referring to a folder selected in Windows Explorer?

You know that helper macro in MFC (pardon my ignorance but I haven't used MFC in probalby 6-7 years) that is used for creating object at runtime, used in Views, I think it's RUNTIME_CLASS or something???
What is the name of the closest pattern for that implementation, obviously it's not a singleton and it's not quite a factory either, or is it?
I am implementing (in another language) a object which does:
1. Prevents direct instantiation by virtue of a private constructor
2. The second object which is used to create the said oibject manages the instances to limit only one per class
So I get the benefits of a singleton while still honoring inversion of control or DIP. Without the global introduced using a singleton.
Cheers,
Alex

I guess that it could be said that the MFC Doc/View architecture closely resembles the Model-View-Controller pattern[^].

Sounds interesting. What language are you working with?

It could be, but more formally I believe MFC and Doc/View are refered to as MVP, unfortunately neither pattern are what I am looking for. I think I may have to discover my own name as it's one part service locator and one part singleton but removed of functionality in both to meet very specific requirements.
Randor wrote: Sounds interesting. What language are you working with?
Only the best, most flexible language in the world. :P
*cough* PHP *cough*
Seriously though, while the language is responsible for some of the most naieve developers and most hackish projects, known to man, like any language if you follow best practices, patterns, etc. It's a real treat to work with.
Cheers,
Alex

Heh, I remember the birth of PHP. I was not doing any Windows development in the mid 90's and was a Unix developer/sys admin. I haven't done any PHP development in over 10 years I would probably be lost in PHP5. The PHP language itself has come a long way.
Good luck with your PHP project.

So you remember it's birth as a series of Perl scripts and being called "Personal Homepage"? :P I started at the time PHP 3 was released...
Back then I was learning/tinkering in C and C++ in the 1990's, it was only when I started thinking I'd like to make a career out of software development that I looked for an easy enterance. Web site projects were plenty and didn't require a BSc. so I started learning JS, HTML and ASP. I hated ASP, looked for an open source solution and started with Perl which led me to PHP (thank god).
It's annoying to develop in, because of the lack of any standard framework (at least a few hundred available -- with new ones popping up each week) unlike MFC, to provide your application with some structure. When fixing or working on existing applications, it can be like finding a needle in a haystack.
One guys interpretaion of MVC and a front controller, actually turns out to be a extremely tightly coupled application bootstrap, front controller, routing, dispatching and more, in one monolithic class over 1000 lines.
Lots of bad practice in PHP but there is a small community dedicated developers trying to change that by introducing patterns, OO best practices, architecture and more.
Zend framework is a good start, with it's design issues and all.
Cheers,
Alex

For making non-sizable MDI window and removing maximize button:
CWnd *pParent = GetParent();
CMenu* pMenu = pParent->GetSystemMenu(FALSE);
if (NULL != pMenu)
{
pParent->ModifyStyle(WS_CAPTION|WS_MAXIMIZEBOX ,0,0);
pParent->ModifyStyle(WS_THICKFRAME, 0, 0);
pParent->ModifyStyle(0,WS_CAPTION,SWP_FRAMECHANGED);
}

Thanks for the reply.
I have tried it.And aslo i have tried in childframe precreate function in CREATRSTRUCT structure .
CREATRSTRUCT cs;
cs ~=WS_MAXIMIZEBOX
which disables the maximize box.
But both the ways gives me the same result.That intially window is maximised and the user can press the restore button.
Once the restore button is pressed, the maximize button is disabled.But this is not the actual requirment that the user should not be able to pres the restore button in initial case also.
Is there is any method so that initially also restore button should be disabled

Hi,
Sorry for the late reply. The code that I showed you is working for me in VS2008 on MDI child windows. If you show me how and where you are attempting to remove the buttons I may be able to help.
Best Wishes,
-David Delaune
