1. What means "the right semantics for the auto_ptr member"?

Right semantics means: "a copy constructor and a assignment operator that make sense for that class", I think. Maybe a deep member copy, maybe different.

2. "disable" means for the class, copy construction and assignment are not needed? Curious. Never thought of a class which does not need that two basic functions.

For instance a Singleton.

Hi CPallini,

I lost your context, "maybe different" is different for what? Any more descriptions?

Well, suppose, for instance, you design a rather complex class (maybe a graphic tool). The class may cache some info to speed up computations. The cached info is part of class internal data but it isn't independent info and should be skipped by assignment operator.

Hi!

I have a problem with TopMost window on Windows Vista.
In Dialog's OnInitDialog method I try to set position by the following code

<br />
<br />
    int cx, cy; <br />
    HDC dc = ::GetDC(NULL); <br />
    cx = GetDeviceCaps(dc,HORZRES) + <br />
        GetSystemMetrics(SM_CXBORDER); <br />
    cy = GetDeviceCaps(dc,VERTRES) +<br />
        GetSystemMetrics(SM_CYBORDER); <br />
    ::ReleaseDC(0,dc); <br />
<br />
//Put window on top and expand it to fill screen<br />
	SetWindowPos(&wndTopMost, <br />
        -(GetSystemMetrics(SM_CXBORDER) + 2), <br />
        -(GetSystemMetrics(SM_CYBORDER) + 2), <br />
        cx+5,cy+5, 0); <br />

that works fine in XP - dialog is realy top most, but on Vista sometimes it is not - some active windows like Firefox can be above of my dialog. I can't understand where is the problem here and how can it be fixed?

hi, thanks for answer.

1. I did not get any visual errors, I've got only strange behavior of the windows on screen. I set for my window TOPMOST order, but in OS it actually appears under any current active window on the screen.

2. I use VC2005.

I found some interesting topic on this problem: http://groups.google.com/group/microsoft.public.vc.mfc/browse_thread/thread/8c9333777d461126/c5ee093565701048[^]

I've used Windows XP SP2 Platform SDK for several months, there are some incomptible problem, like CFileDialog crashing.

I wonder if there is a more compatible one.
What about Windows Server 2003 R2 Platform SDK?

Thanks.

Windows Server 2003 R2 Platform SDK February 2003 Edition is the last version compatible with VC6. I cannot tell you if your problems will go away however.

Hello everyone,

I am compiling the client part program of COM reentrancy problem. Does anyone know what is the problem?

(BTW: server part program can compile, link and register ok.)

I am using MSVC 2008 + x64 Windows Server 2003. Is it because the code is old and in the newest SDK we need some code change to migrate?

http://www.codeproject.com/KB/COM/sta_issues.aspx

1>stdafx.cpp
1>d:\exercises\stareentr\stareentr\client\stdafx.h(16) : fatal error C1083: Cannot open include file: 'atlapp.h': No such file or directory

Hi,

It seems, problem is only in some project settings.

Check "additional include libraries", linker input etc.

Thanks,
Suman

The value for me is, odbc32.lib odbccp32.lib comctl32.lib. But what I met with is compile error, why do you think it deals with linker options? Smile | :)

Hi,

I mainly wanted to tell it will be only project settings and not programming error.

I will tell you when I find solution.

Is there use of SetSDKPath() in ur project?

Thanks,
Suman

Thanks Suman,

I found atlapp.h belongs to WTL 8.0 and when I install the library and add the include path of WTL 8.0 to the project additional include path, the client.cpp can compile.

But for the resource file, there is still compile error,

1>.\client.rc(10) : fatal error RC1015: cannot open include file 'atlres.h'.

Do we need special settings for the resource file?

George

Hi,

Try adding "C:\Program Files\Microsoft Visual Studio\VC....\WTL\include" to "Additional Include Directories" under C/C++ and Resources tab in your Project Settings dialog.
