There is nothing wrong with using MFC in an nt service. Classes like CString and CStringArray can be very handy within a service. However, using the CSocket class in a service can be hard because it relies on a hidden window to process messages. Without a message pump, the event notification methods (OnAccept, OnReceive, etc.) won't be invoked. But it is not impossible to make it work. "*I might be absolutely wrong*." I might be a little bit wrong. Re: damn CSocket ! Nish Nishant6-Mar-02 1:36 Nish Nishant 6-Mar-02 1:36  XiangYangLiu wrote: There is nothing wrong with using MFC in an nt service.

He particularly discouraged the use of CString.

He particularly discouraged the use of CString." I wasn't impressed by the comments. I am afraid the issue is blown out of proportion (again). Re: damn CSocket ! 6-Mar-02 1:03 6-Mar-02 1:03  Your code in the dialog based app worked because the app has a message pump. CSocket uses a hidden window. The OnAccept method will only be called when messages got processed. Your nt service most likely does not have a message pump. A simple solution to this problem is 1) Keep your code in the dialog based app. 2) Make sure the dialog based app does not need user intervention (no modal message box, etc.) 3) Start the dialog based app from a special nt service. Good luck. Re: damn CSocket ! Giles6-Mar-02 2:48 Giles 6-Mar-02 2:48  There is an underlying CSocket class in this article, that is designed for use with NT services. Also check out a few of Mr Naughter's other Articles, as he knows his Winsock under a service very well indeed. This class can be used with either GUI Applications or Services - its happy anywhere. He's developed loads of things for use with NT Services.

For each HWND returned, call GetProcessThreadProcessId and compare results with gived PID. [edit] Of course, this is GetWindowThreadProcessId, as Nish pointed out.

I can't find anything on CodeProject. Can anyone point to some info on how to achieve this. Thanks. Regards, Parish while (!asleep) code(); Re: Detecting when running from the command line Nish Nishant5-Mar-02 23:24 Nish Nishant 5-Mar-02 23:24  msdev uses a weird technique to accomlish this. there are two files. msdev.com -> a console program msdev.exe -> win32 program when you run msdev it is the com program that runs first because com has predominance over exe If it has a /? then the msdev.com prints out all the info If it does not then it will spawn msdev.exe Nish [Signature temporarily down] Re: Detecting when running from the command line Parish5-Mar-02 23:54 Parish 5-Mar-02 23:54  Ah yes, I'd forgotten about that trick. Unfortunately it is not an acceptable solution in this case. I failed to mention that this app already has some handling for outputting the info but the text only appears if the output is piped to MORE: myapp /? | more The app calls GetConsoleMode() and SetConsoleMode() but I suspect that these are being passed the wrong parameters (the app was originally Unix which uses a different mechanism to handle this). while (!asleep) code(); Re: Detecting when running from the command line moliate6-Mar-02 1:05 moliate 6-Mar-02 1:05  Perhaps you could compile a msdos stub into the program (using /STUB: linker input)? I don't know if this works well for NT (using cmd.exe)... Another solution might be to check the main window class for ConsoleWindowClass. /moliate Re: Detecting when running from the command line Joel Lucsy6-Mar-02 4:52 Joel Lucsy 6-Mar-02 4:52  All you need is GetCommandLine(). When arguements are present, do something else. Joel Lucsy (jjlucsy@ameritech.net) Re: Detecting when running from the command line Parish6-Mar-02 20:22 Parish 6-Mar-02 20:22  I know that, and the code is there, but the problem is getting it to send the output to the correct place, i.e. the CMD window the app was started from. I've found the reason *why* it doesn't work from reading the MSDN section about WinMain() but haven't found a solution. When a win32 GUI app is run from the command prompt and I/O redirection is included *on the commandline*, e.g. C:> myapp | more C:> myapp > filename then the apps starts with its' I/O linked to the pipe or redirect. However, if no redirection is included on the commandline then the app has no connection to the window (instance of cmd.exe) that it was started from. As the command prompt returns as soon as the app starts there appears to be no way, from within the app, of linking to the window it started from, they run as 2 unrelated tasks; even usning "START /W myapp" does not achieve the desired result. This contrasts with Unix where the apps' I/O is connected to the shell it was started from by default, even if the app is started as a background task (so the command prompt returns immediately - normally this doesn't happen until the app exits). When starting from a menu or icon it is usual to redirect stdout and stderr to the console (myapp > /dev/console 2>&1) so you can see any messages. If you put this simplified piece of code in WinMain() and run the app from a CMD window you will not see any output unless you redirect on the commandline: if (__argc > 1) { printf("Hello, world\n"); exit(0); } ...... I assume that, by default, std{out,err} go to NUL?? while (!asleep) code(); File names inside a folder..
