Make build compatible between UNICODE, ANSI and MBCS.
Basically, in an Unicode build, you want all "normal" string constants to be Unicode (wchar_t *), and in an ANSI build, all of them to be ANSI (char *).
A UNICODE string constant is indicated by an L : L"Hello" is a UNICODE Hello (independent of UNICODE or ANSI build)
_T("Hello") evaluates to "Hello" in ANSI builds, and L"Hello" in UNICODE builds.

Q1:
Does anybody know the overhead of a complete APC "round trip" vs. a synchronous execution - i.e.
Thread A: QueueUserAPC
Thread B: processes the request, and sets an "ready" Event at the end
Thread A: Waits for the "ready" event
vs.
Thread A processes the request
Assuming Thread B is in an alertable state already.
Q2:
Are there limitations on the APC queue, how many can / should be queued?

Threading is a cool feature, because it cost not much on performance. If you have an UI and a long process you should do this, because than the UI is released (for refresh, user actions)
If I knew what an APC is maybe I could answer Q2.
Try this @ home. (B&B)

Asynchronous Procedure Call: using the QueueUserAPC function, you can "ask" another thread to execute a function. It's a simple replacement for the worker thread to wait for a message or "kickToGo" event.
I just ran some tests today, and I'm pretty pleased. The operations I have to run are as short as 3 ms; APC overhead seems to be only up to 3% in the long run (tested on 3 systems).Behavior gets a little bit weird (on one box, the async processing takes 30% more on one box, and 30% less on another - which really is puzzling)

If you're only interested in RAS connections, you can use the function RasConnectionNotification which informs you about connections established by RAS.

Hello,
I have application where i need to show modal message window.
It should be custom ( not AfxMessageBox ) , so i built a class
CPopupDlg which is inherited from CDialog and it's a DLL , because i need to call it from different dialogs ( and i don't want to duplicate it . It doesn't have title bar.
CPopup constructor gets "CWnd* pParent" ( for z-order , etc )
So , i call for it in following way ( from another dialogs ):
CPopupDlg* pPopupDlg;
pPopupDlg = new CPopupDlg( this );
pPopupDlg->SetPopupMessage( m_strPopupMsg );
pPopupDlg->DoModal();
The dialog itself works fine , showing needed msg with custom
colors , custom buttons , etc.
BUT , there is a problem.
There's a title above CPopup dialog ( while originally it doesn't
have title bar ) of dialog calling for it.
For example , if calling dialog has title text "My Test Window"
this text will appear in title above CPopup dialog .
Here's screenshot
Here's entry from .rc file
/////////////////////////////////////////////////////////////////////////////
//
// Dialog
//
IDD_POPUP_DIALOG DIALOG DISCARDABLE 0, 0, 187, 92
STYLE WS_POPUP
FONT 8, "MS Sans Serif"
BEGIN
DEFPUSHBUTTON "OK",IDOK,130,7,50,14,NOT WS_VISIBLE
PUSHBUTTON "Cancel",IDCANCEL,130,24,50,14,NOT WS_VISIBLE |
WS_DISABLED
CONTROL "popupOK",IDC_POPUP_OK,"Button",BS_OWNERDRAW | NOT
WS_VISIBLE | WS_DISABLED | WS_TABSTOP,15,65,55,15
CONTROL "popupCancel",IDC_POPUP_CANCEL,"Button",BS_OWNERDRAW |
NOT WS_VISIBLE | WS_DISABLED | WS_TABSTOP,115,60,50,20
END
Any help greatly appreciated ( it's pretty urgent ),
thanks a lot

The information you provided is probably not sufficient.
I made a test program and it works fine; i could have send it to you if i would have know your email address...

HI ALL,
Anybody knows how windows get painted on the Screen? As far as I know GDI32 does most of the works.But as far as actual windows concern,We do not have more then CreateWindow.So how the CreateWindow does it's work? anybody has an idea? Also I want to know some clear differences between Windowing System and GDI stuff.

Does anyone have any ideas on reading the information from .dsp/.dsw files, or, failing this, using the Visual Studio automation interface to read project settings (if thats even posible) ??
My aim is to be able to dump out a projects settings - compile and link options etc so that they can be compared to a reference (read working) project.
I guess I can export a makefile and use that ... Ideally I would convert the relevant parts to XML.
Thanks, 'G'
sorry, no humour today - Ive had 6 hours sleep for the past 3 days, anything I could say would be interpreted as thinly veiled sarcasm....

Don't waste you're time on this. The automation interface is pretty stupid, and one of the many things you can NOT do is enumerate all the project's files (or if you can I have yet to figure it out - now watch, you'll be undaunted by this and figure it out in 15 minutes making me look like an idiot!). You can enumerate all the windows that are open, but this is not very useful.
If all you want is basic project settings from the configuration, you can get this info. Look at the IConfiguration interface for this
But if you really want to deal with what files are in the project, then you'll have to write/hack/cobble together some little parser to read in the dsp file.

Yeah, Jim is right, you'll have to hack together a DSP parser. Trust me, it sux. There's some classes which can give you a start on this, in my article:
http://www.codeproject.com/useritems/includefinder.asp
The classes you may be interested in will be in DSObjects.h, DSObjects.cpp, VC6Objects.h, and VC6Objects.cpp.
They are very far from perfect (and only interpret some of the compiler settings), but like I said, it's a start. If you were working with VC7, you'd be in a lot better shape to accomplish this task.

Many thanks - went back to your article, and its a ripper - I didnt connect 'how' you found the files, I took (without checking the details) the naive opinion that 'he probably found all the '.h, .cpp etc' files from a directory list and then parsed & mapped them'
your solution is much better ...
roll on the day I get VC7 at work !!!!

Why can't you just compare the master .dsp with the current one?
I've got some basic code to read the list of files in a .dsp which Chris Richardson has used in his C/C++ Include Finder. See his post. I assume Chris's code will be more usefull as I assume he's built extra stuff on top of what I sent him, and made some nice classes.

Neville,
Has it ever been pointed out that the url name "getsoft.com" perhaps conveys the wrong idea ? 
Just wonderin'

Hi Jim,
Well not really, however my company name "Soft As It Gets' causes no end of frivolity, especially when you are talking to people who don't know we write computer software.;) When they ask what we do, I always ask them "what do you think we do?". Lots of fun.
Like many things in life this company name wasn't planned, and wasn't one we really wanted, but in hindsight it couldn't be better.
PS. I did have someone approach me to buy the URL getsoft.com a few years back.

yes, for a base I guess, if they had the same origins, I guess 'Beyond Compare' or even Windiff would show differences - but its also an interpretational problem, in the context that I'd break down the meaning of the compile/link settings and show what the meant, rather than a line like :-
/nologo /MDd /W3 /Gm /Gx /ZI /Od /D"WIN32" /D"_DEBUG" .. yada yada
I'd say what /Gm, /Gx actually did .. and, Windiff etc will point out that
/nologo /MDd /W3 /Gm /Gx /ZI /Od /D"WIN32" /D"_DEBUG"
is different from
/nologo /MDd /W3 /GY /Gx /ZI /Od /D"WIN32" /D"_DEBUG"
(note the /Gm -> /GY), but it wont 'interpret' the difference

Many Thanks to Jim/Neville/Chris for your helpfull comments - I did see the 'include finder' but didnt connect the dots - I also saw a post where someone thanked Neville for his code on the subject, and I could have phoned him (being in Australia as well), but thats not the spirit of CP ..
If I eventually manage to turn out something useful, I'll post it back here, could take some time but !!
cheers fella's
Garth

I am looking for some advice/help on how to implement some code that is very tightly integrated with the windows explorer.
In windows XP, Microsoft implemented a “Compressed (Zipped) Folder” for .zip files. This is exactly what I want to do but for a proprietary file format. I would like to reuse as much MS code as possible so that I don’t have to re-implement all kinds of functions.
I would like a call-back function when a file is added to the sudo folder and a call-back function when a file is removed (or read) from the sudo folder. Everything else should behave exactly as if it were a regular folder.
Thank you in advance for your help.

look into Mike Dunns Shell Extensions for Dummies articles. You probably want a Shell Namespace extension. This is what MS does for this kind of thing.
