 - new and delete operators for a class.. I want to add a new operator for one of my classes, that looks like this: void* operator new(size_t Size, void* tag); What should look like the delete operator? If I use something like this: void operator delete(void* Buffer, void* tag) it will not be called when I "delete" a class instance. If I use a delete operator like this: void operator delete(void* Buffer) It will be called, but I will get a complie warning because it's not matching my new operator. So, what is the right delete operator? Tag: Explicitly calling constructors/destructors Tag: 243001

 - Using GDI+ in C++ Hi there, I'm having problems include gdiplus.h in my C++ application, I get a huge list of compiler errors. My stdafx.h looks like this #define WIN32_LEAN_AND_MEAN // Exclude rarely-used stuff from Windows headers #include <windows.h> #include <windowsx.h> #include <stdlib.h> #include <malloc.h> #include <memory.h> #include <tchar.h> #include <stdio.h> #include <string> #include <time.h> #include <iostream> #include <Winsock2.h> #include <gdiplus.h> << Causes 560 build errors! using namespace std; I've tried removing WIN32_LEAN_AND_MEAN but that just caused different errors to occur. Any ideas with this one? I'm hoping that I do not need to use MFC or ATL with this do I? I need to use only standard windows libraries. Thanks loads in advance!! BTW. Look below for some of my error list Nick. c:\Program Files\Microsoft Visual Studio .NET 2003\Vc7\PlatformSDK\Include\GdiPlusImaging.h(67): error C2059: syntax error : 'public' c:\Program Files\Microsoft Visual Studio .NET 2003\Vc7\PlatformSDK\Include\GdiPlusImaging.h(67): error C2059: syntax error : 'public' c:\Program Files\Microsoft Visual Studio .NET 2003\Vc7\PlatformSDK\Include\GdiPlusImaging.h(67): error C2059: syntax error : 'public' c:\Program Files\Microsoft Visual Studio .NET 2003\Vc7\PlatformSDK\Include\GdiPlusImaging.h(67): error C2059: syntax error : 'public' c:\Program Files\Microsoft Visual Studio .NET 2003\Vc7\PlatformSDK\Include\GdiPlusImaging.h(67): error C2059: syntax error : 'public' c:\Program Files\Microsoft Visual Studio .NET 2003\Vc7\PlatformSDK\Include\GdiPlusImaging.h(67): error C2146: syntax error : missing ';' before identifier 'IImageBytes' c:\Program Files\Microsoft Visual Studio .NET 2003\Vc7\PlatformSDK\Include\GdiPlusImaging.h(67): error C2146: syntax error : missing ';' before identifier 'IImageBytes' c:\Program Files\Microsoft Visual Studio .NET 2003\Vc7\PlatformSDK\Include\GdiPlusImaging.h(67): error C2146: syntax error : missing ';' before identifier 'IImageBytes' c:\Program Files\Microsoft Visual Studio .NET 2003\Vc7\PlatformSDK\Include\GdiPlusImaging.h(67): error C2146: syntax error : missing ';' before identifier 'IImageBytes' c:\Program Files\Microsoft Visual Studio .NET ....

 - VC 7 DLL Export Hello, i want to create a dll with some exported functions. Normally this isnt a problem, but with VC 7 and my current problem ive got the following Linker warning/error: warning LNK4017: EXPORTS statement not supported for the target platform; ignored I created the project using the "Win32 Project->DLL" wizard. The function to export is defined as WINAPI and listed in the EXPORTS section of the def file. Without the def file all things are compiled/linked without problem, but also without export ;) Thank you for any ideas in advance.

 - Do you think this is possible? I have a third party 'EXE' that contains a number of windows in it. By sending a message to the EXE I can get it open any screen. But I need this screen to be created in *my* windows app ! or at least to set the parent of the created form equal to my MDI ? Is this possible at all ? In short , what I am trying to achieve is to create something like a notepad window within my MDI. Is this possible ? Tag: Explicitly calling constructors/destructors Tag: 242989

 - Buffer Overrun Hi, I'm working on a Direct3D Project. This might not relevant though but part of it has a DirectInput routine. The d3d app launches and exception throws at me saying that buffer is overrun and the app must be terminated. What most likely be the cause of buffer overruns?

 - redrawing in control with Invalidate() I have a CStatic which displays a plot - X, Y axes, tickmarks, etc. I want to change scaling of the plot by entering new ranges of X and Y. I call an overriden OnPaint for that: CPlot::OnPaint() { this->Invalidate() CPaintDC dc(this); ... draw lines and labeles DeleteDC(dc); } The problem is that it gets redrawn on top of the prevous drawing, w/o first erasing the prevous drawing. I also tried InvalidateRec() w/o success. I guess I can fill the whole area with a background color, but this seems lame. A search of this group showed that Invalidate should work, but it doesn't! What's the solution then? BTW... is there a quota of how many questions per day one can ask here? :) I wonder if I am abusing this group. Tag: Explicitly calling constructors/destructors Tag: 242942

 - Assertion error when using Free (non-local pointer) Hi all, my application uses callback function in DLL (Written in C), The DLL sniff's the network card and then allocates new data dynamically using malloc() function , Then the data (pointer) passed to the host application (MFC), After I use the data and copying it, I'm trying to free the space using Free() But I get an Assertion error, After running step by step inside MS code I see that free() function check's if the new memory was allocated inside the current app (local) , if the memory wasn't allocated inside then Assertion error occur . How do I free memory from other application? [DLL] | | | | [App] steps : 1.. Application init the DLL and run it, the DLL now runs separately from the app . 2.. when ever the DLL find network data , it will allocate memory space ,and process incoming data 3.. Then it will notify the application using callback function, and pass the application a pointer to the new allocated space. 4.. the application uses the memory 5.. Application try to free the memory using the free function - Assertion Error !!!!! Env : Vs.net IDE (NO DotNet involved , pure c/c++ code .)

 - Run-time stack frame checks - false alarm? I get a run-time check failure message, saying: "Run-Time Check Failure #2 - Stack aroung the variable ... was corrupted." 1. I'm almost sure that my stack is not corrupted! 2. When I copy the func to another file, rename the copy, and call the copy instead, the run-time check message does not show. My question is: when such a message appears, does this necessarily mean that there is a problem with the source or this may be a false alarm?

 - Multiple compiler errors - this could hurt your eyes... sources : private, but very awesomely ass-huge sources. bug : I'm compiling, and on many occasions, the compilation dies with this. it ALWAYS dies this way, i think. hint : always seems to crash on cxx files (c++ surely?) possible solution : move to gcc? informations : Compiler : Microsoft (R) 32-bit C/C++ Optimizing Compiler Version 13.10.3077 for 80x86 -- the one that comes with Vs .net 2003 OS : Windows XP with Multilanguage user interface (we're msdn members where I work) tree : a mix of C, C++, and rarely but sometimes fortran. UC : small P4 1.7 with 512 mb RAM. strangely, all seemed to compile propely with the VC++ 6.0 compiler. Some people tell me it's just that .net plain s***s. While i'm more of the GNU/F_OSS breed and tend to have these type of opinions, this time i don't have them, as i am slowly having respect for microsoft. so, did VC .net 2003 break the compiler? if so, does VC Whidbey un-break it?

 - LNK4003: invalid library format -- why? I'm trying to compile and link a simple program which uses a third party DLL. When I try to link I get the error message "gci.dll : warning LNK4003: invalid library format; library ignored" I've run tool called Dependency Walker to take analyze the dll and it returned the information below, along with the warning: "Warning: At least one module has an unresolved import due to a missing export function in a delay-load dependent module." Would this warning be enough to stop the link? Does anyone have any ideas about what the problem could be?

 - Exporting unmangled name from C DLL I'm new to the Microsoft C compiler and I'm having a problem. I'm trying to build a DLL from C source code and the compiler is exporting mangled names. I can't seem to figure out how to export unmangled names. Here's the source code for my function: __declspec(dllexport) long __stdcall TestExport(long integer) { return 0 ; } Can anyone explain how I can prevent the mangling? Do I have to use a DEF file to prevent mangling? I'm using this version of the compiler: Microsoft (R) 32-bit C/C++ Optimizing Compiler Version 13.10.3077 for 80x86 Thanks in advance.

 - re-sharing memory I am experiencing a problem where the data in a structure in shared memory is not being preserved. Process A creates the shared memory, spawns and passes the name to process B Process B opens and initialises the shared memory. All comunications between processes A and B work as expected. Process B then spawns another process (C) and passes it the name of the same shared memory. When Process C attempts to read an integer value in the shared memory, I am finding it to be set to a random large number, and not the value set by Process B. Note that I did not write Process A, nor design the structure used to share memory, I simply want to read and write values in processes B and C. Does anyone know what can cause this behaviour and how to prevent it? I am using VS.Net 7.1 WinXP. Thanks in advance, Steph Tag: Explicitly calling constructors/destructors Tag: 242882

But now all my breakpoints for that application break on mscorwks.dll instead of the point in code where the breakpoint was located. Can anyone help me with this?

 - Function pointers and dynamically loaded DLLs In my program, I load dynamically a DLL and I'm able to get a function pointer of type "int (__cdecl *)(void)" of any function in the DLL. If a DLL has a static class function, which calls the constructor and returns a pointer to the constructed instance of the class, then I don't have any problems. However, if a DLL doesn't have such static function, then I can't get it working. I'm able to get a function pointer to the class constructor, but I have no idea how to call the constructor in the way that that it also creates instance of the class (with 'operator new' obviously). Calling just the constructor, of course, doesn't return a valid instance of the class. The header of the DLL is basically like this: class dllclass { public: __declspec(dllexport) virtual ~dllclass(); __declspec(dllexport) dllclass(); __declspec(dllexport) virtual void dosomething1(); __declspec(dllexport) virtual void dosomething2(); __declspec(dllexport) virtual void dosomething3(); }; I cannot change the DLL, so that kind of workaround isn't possible. Any suggestions? Is it even possible? Thanks in advance. PS. I originally posted this to comp.lang.c++, but was asked to post it to this newsgroup instead since it'll require some compiler specific code to work.

 - forward declaration and #include problem I have a global pointer to the main dialog class declared in CMainDlg.h as extern CMainDlg* g_pMainClass; ... and declared and initiated in CMainDlg.cpp as CMainDlg * g_pMainClass; CMainDlg:CMainDlg(){ g_pMainClass = this;} I am now trying to use the global pointer to access the main dialog's controls from a modeless child dialog. In CChildDlg.h I did: class CMainDlg; extern CMainDlg * g_pMainClass; This compiles fine, but when I try to use the pointer in CChildDlg.cpp, it says that CMainDlg is not defined. If I include CMainDlg.h into CChildDlg.cpp, as suggested by Igor, it complains about classes in CChildDlg.cpp being undefined. Could anyone help me with this? In principle, I don't undestand how files can reciprocally be included into ea other... would not it generate some kind of infinite loop? >>>>>>>>>>>>>> Add forward declaration: class CMainDlg; > class CPlotDlg { > public: > CPlotDlg(CWnd* pParent); CPlotDlg(CMainDlg* pParent); > pretected: > CWnd * m_pParent; CMainDlg * m_pParent; > } Now simply #include "MainDlg.h" in PlotDlg.cpp. Enjoy. > CPlotDlg::UpdateData() { > data_in_plot = m_pParent->data_in_main_dlg = ;} > Plus, I want this to work for any generic CWnd *, > not just for CMainDlg.

 - sendto() return WSAEINTR Hi all, Sorry that maybe I should not post it here, but it seems that HERE there are the experts. I wrote a program, which receive data from USB and then call sendto() to send the data to this machine's own network port, and then a download application will handle the packets. On one machine this program works well, but on many other machines, sendto() just return WSAEINTR. With this return value, I have no idea how to modify my program or do sth else to solve the problem. I did not get a good answer from MSDN about WSAEINTR. Anyone know the solution? Thank you in advance. Best regards --- Astroller Lee Tag: Explicitly calling constructors/destructors Tag: 242849

 - my function is already defined in myDialog.obj! Please help Hi, I am pretty good with c++ but quite new with the visual studio environment and especially the MFC so if this is an obvious problem please excuse me but I still need help! Here it is. I created a simple dialog (my dialog class is BlobeyDlg) based program as a matter of fact I haven't added anything to it except the following code for when the user clicks on the ok button: GLInterface a; a.dostuff(); and of course I have added #include "GLInterface.h" at the top now in GLInterface.h I have: #include "someincludes.h" GLInterface { ... private: static GLInterface* inst; ... }; GLInterface * GLInterface::inst = 0; I get an error during the linking phase of the build: Blobey error LNK2005: "private: static class GLInterface * GLInterface::inst" (?inst@GLInterface@@0PAV1@A) already defined in BlobeyDlg.obj Blobey fatal error LNK1169: one or more multiply defined symbols found I have never added my own structure to a program in this environment before and I think its pretty clear I'm not integrating something correctly. Any ideas? Thanks, George Tag: Explicitly calling constructors/destructors Tag: 242843

 - Strange unresolved external I have a WTL MDI application. I have a template class I am using as a base class for all docking windows. Any window I have that needs to be docked is derived from this template class: // Base docking window template class template <class TThisWnd, class TImplWnd, class TWndTraits> class WBaseDockingWnd : public CWindowImpl<WBaseDockingWnd, TImplWnd, TWndTraits> { }; // Properties window class WPropertiesWnd : public WBaseDockingWnd<WPropertiesWnd, CListViewCtrl> The problem I am having has to do with the fact that one of the member functions of WBaseDockingWnd is calling the GetSystemMetrics() Win32 API function. When the linker comes to linking the actual implementations (i.e. my properties window) it complains that GetSystemMetrics() is unresolved, even though it managed to resolve it just fine for the other places where I am using it. I turned on the /VERBOSE option for the linker and this is what it is telling me: // Found it fine when I used it in MainFrame.cpp Found __imp__GetSystemMetrics@4 Referenced in MainFrame.obj Loaded user32.lib(USER32.dll) // Error in PropertiesWnd.cpp PropertiesWnd.obj : error LNK2001: unresolved external symbol _xGetSystemMetrics@4 I noticed that the mangled names don't match in the two references. I don't know if that makes any difference though. When I call GetSystemMetrics() from within my base docking window class I do qualify it with the global scope operator (e.g. ::GetSystemMetrics()) so it should be resolving to the correct function. I don't have any function I have implemented with the same name. Any one know what is going on here? Thanks Tag: Explicitly calling constructors/destructors Tag: 242842

 - Exporting global data from a DLL to an EXE Hi, I have a "Win32 Application" and I must use some global data defined(and initialized) in a DLL linked to the Application. As suggested by MSDN,I have exported this global data from the DLL in this way: - In the DLL, I have used the keyword DLLEXPORT - In the EXE I have used the keyword DLLIMPORT But when I run the EXE the application crashes! The problem is that, in the EXE, the imported global data are all equal to zero and the application doesn't see the initializationsdone in the DLL! Does someone know where is the problem?

 - GetObject() and BITMAP.bmBitsPixel Hi, Env: Windows2000 SP4, VC++ 6.00 I always get an wrong BITMAP.bmBitsPixel when geting BITMAP using GetObject(). For example, (1) I created 32*32, 4bit(16color) bitmap file without compression by Windows' Painter or just by VC's IDE Resource Editor; (2) Load it by LoadImage() from my harddiskm, or by LoadBitmap() from the Resource; (3)get BITMAP as follows, BITMAP bm; int iRet = GetObject(hBmp, sizeof(BITMAP), &bm); Then, I got bm.bmBitsPixel = 32(WHY NOT 4?)? And bm.bmWidthBytes = 128(WHY NOT 4) No matter the orignal file is 8bit(256color), 16bit, or 24bit, bm.bmBitsPixel always = 32, and bm.bmWidthBytes = 128. But if the orignal file is 1bit(monochrome), then bm.bmBitsPixel = 1. Tell me why if you could. Thanks! William Tag: Explicitly calling constructors/destructors Tag: 242807

CBitmap m_bmBackGroundBitmap; CBitmap m_bmMemBitmap; CDC m_dcMemBackGround; CDC m_dcMemDC; ... }; So the pair m_bmBackGroundBitmap/m_dcMemBackGround is used to store (permanently) the background of the window (for example the wooden chess board - without pieces), and the pair m_bmMemBitmap/m_dcMemDC is used for drawing the current situation (a chess board with pieces,,, someone moved ...), so it holds temporary the current picture (drawn to the screen). So on windows class OnDraw() funktion, I will just call: m_FlickerFree.Draw(pDC); where CFlickerFree m_FlickerFree; So CFlickerFree 's Draw does the actual BitBlt for pDC, and the picture can be seen on the windows client. Question regarding this: Is it good to have those memory DC's like I have so that they are members of the class *or* is it better to always create(/delete) them temporary on Draw-funktion (so that they are not members on CFlickerFree class)? Is it the same? I think the bitmap must be a class member (??),,, or could it be bettter to reload the bitmap every time you draw (I dont think so ..)? ''' Then another implementation question regarding this. Next I want to create a class taking care of moving bitmaps/sprites --- this could be for example a chess piece picture on the board. Is it a good idea to first create a CFlickerFree object for the chess board picture, and then create another similar , say CPiece, class which again holds the memory CDC and corresponding bitmat objects (for the piece piecture) as a *members* of this class? And then first BitBlt this CPiece object onto CFlickerFree and after that call CFlickerFree 's Draw funktion with Windows pDC parameter to bitblt the whole picture onto the screen? Any better idea? If I ponder this myself it might take couple of days, so you can greatly help me here... maybe you have done this before? thanks Tag: Explicitly calling constructors/destructors Tag: 242797

 - iostream debug ?! Hi group, I am working with vc7.1. What are the requirements that I can debug in iostream (eg std::ostream). At the moment my debugger jumps over each call (eg. operator<< or write() ) but I wan´t jump in. A few days ago it was possible with no special setup. Any hints ?

 - namespace giving C2059 I am trying to port some code to Visual C++.net from codewarrior. My code defines a struct "vec3" which apparently conflicts with something in directx (somehow it worked fine in codewarrior). To solve this I tried putting my declarations in a namespace like this: namespace sk { struct vec3 { // my stuff }; // other declarations } This gives error C2059: syntax error : 'namespace' which points right to line 1. Every namespace dec in the code (including those that have always worked in codewarrior) seems to be giving this error, EXCEPT in modules that don't include any win32 header files. Thanks in advance for any ideas. -Dan Tag: Explicitly calling constructors/destructors Tag: 242784

 - Proper Reading of MAP/COD files I am wondering if I am doing this right. Generally, if and when I get a DR WATSON report from a customer, I can use this to zoom in on the fault in our code simply by looking at the OP codes in the report and finding it in our COD files. In most cases, this is sufficient to find whatever is the problem. In my last release I added a C++ exception trap and it is now recording the fault in my own custom log file. Here is an example fault recorded: ---------------------------------------------------------------- Application exception occurred: Date : 2/16/2005 4:04:50 AM Computer : TPAP1IMWMA03 ---- Exception Information ---- Exception : C0000005 - Access Violation Location : 0832757A Access Address : 00000001 (read) Registers : EAX=00000001 EBX=00000000 ECX=1E166780 EDX=00000038 : ESP=11E0C8E8 EBP=1E166780 ESI=1E166AE8 EDI=7C57B5A8 : EIP=0832757A EFLGS=00010283 : CS=001B SS=0023 DS=0023 ES=0023 FS=003B GS=0000 Stack Trace : 1E224F20 00000000 00000000 00000000 : 00000000 00000000 00000000 00000000 : 00000000 00000000 00000000 00000000 : 00000000 00000000 00000000 00000000 : 00000000 00000000 00000000 00000000 : 00000000 00000000 00000000 00000000 : 00000000 00000000 00000000 00000000 : 00000000 00000000 00000000 00000000 The location 0x0832757A is my DLL module, XYZ.DLL (we load our DLLS in 0x08xxxxxx ranges), plus I know that based on other report info (not shown) showing the calling parent which uses this XYZ.DLL module. In lieu of working on a similar OP code dump showing the fault location (something I will check out in the future), using the XYZ.MAP file, I see the location is near: 0001:00026540 ?ZapArray@TScriptExecutor@@AAEXXZ 08327540 f exec.obj 0001:00026580 ?ZapString@TScriptExecutor@@AAEXXZ 08327580 f exec.obj Based in this, the fault occured in the ZapArray() function? Correct? So next I took the difference: 0x0832757A 0x08327540 ---------- 0x3A = 58 bytes and looked in the EXEC.COD file, for the ZapArray function and counted 3A bytes. Am I correct so far? The problem is that the ZapArray() ends at 0x33 bytes. Am I going about this correctly?

 - CRichEdit2View msftedit.dll RichEdit50w msftedit_class I'm trying to use a CRichEditView in VC++ .NET 2003, but I want it to conform to RTF 4.1 or 5.0, using msftedit.dll. I've tried everything I can, but I can't get it to stop trying to load riched20.dll. I've noticed that Wordpad in XP will handle the new RTF, but the WORDPAD example in VC.NET will not. When I look at the XP Wordpad with a hex editor, I see references to CRichEdit2View, which is not documented anywhere I can find. Looks like MS has developed a new class to handle the new msftedit.dll, but hasn't passed that on to anyone. Does anyone have the source code for the new XP Wordpad, or an MFC Class that implements RichEdit50W? I've tried modifying afxrich.h, richedit.h, winctrl4.h, viewrich.h, etc., to use #define MSFTEDIT_CLASS L"RichEdit50W", but it's not working. Maybe I need to recompile VS.NET after I modify the files. How do I do this? Anyone have source code for this or an answer? TIA, Jim Tag: Explicitly calling constructors/destructors Tag: 242758

 - communicating with parent class I did some search on this here, but still I can't make it work. I have a main control, CMainDlg, from which I invoke another modeless control, CPlotDlg. m_plot_dialog = new CPlotDlg(this); The two classes are in separate files. I now need CPlotDlg to access a variable in CMainDlg. Here's what's inside CPlotDlg: class CPlotDlg { public: CPlotDlg(CWnd* pParent); pretected: CWnd * m_pParent; } CPlotDlg::CPlotDlg(CWnd* pParent) : CDialog(CPlotDlg::IDD, pParent){ m_pParent = pParent;} CPlotDlg::UpdateData() { data_in_plot = m_pParent->data_in_main_dlg = ;} I can't compile this, since data_in_main_dlg is not a member of CWnd * at the compile time. How can I make CPlotDlg aware of variables in m_pParent, if m_pParent, esentially, gets defined only at runtime? If, I declare m_pParent as CMainDlg *, instead of CWnd *, it complains, too, since CPlotDlg.h gets included into CMainDlg.h, not the other way around. Manually including CMainDlg.h into CPlotDlg.h generates re-definition errors. Plus, I want this to work for any generic CWnd *, not just for CMainDlg.

 - C++ vs. C# regarding performance Hello We are about to dive into a new application for a client. This application is going to have database reads from multiple tables (probably just one sql query) every 500ms or less. Once I get my results back, I need to perform some action with those results, the quicker I get my results back, the quicker I can peform my action. The database is MSDE and is going to reside on the local machine. I was wondering if anyone had any information on performance between C++ and C#, specifically regarding database reads. Generally I have used C# and ADO.NET for database driven applications, but performance is a real concern here, and can be a deal breaker between C++ and C#. Please try to be as objective as possible. Also what technology is reccommended for connecting to an MSDE database via C++. ADO? Thanks. Ryan Tag: Explicitly calling constructors/destructors Tag: 242716

 - Redirecting problem when printf is used? I have a time consuming console unmanaged application whose output I am redirecting to a managed application and dumping it in a listbox. The problem I am seeing is that when my console application is using printf's the managed application blocks even when I am using ReadLine() of streamreader. Seeing no clue as to what was happening, I finally converted all printf's into Console::Writeline and set Use ManagedExtensions to true. Then it I could see all the output line by line as it was output by the console app! Any reason as to what is this behaviour of printf vs WriteLine?

Suppose you have a memory pointer to some allocated memory and a class.
How can you call the constructor of the class so that it operates on your
memory?
The same question goes for the destructor.

Something like this:
class A;
void* tmp_buff;
((A*)tmp_buff)->A();
((A*)tmp_buff)->~A();

VC allows a syntax like that, but it isn't legal C++. You need to look up
"placement new" and pay attention to alignment and other considerations.

>((A*)tmp_buff)->~A();

That's legal, assuming tmp_buff contains a live A.

A few suggestions:

- Google for "placement new"

- See http://www.parashift.com/c++-faq-lite/dtors.html#faq-11.14

- You might want to look at using std::allocator<> in the STL

- You might want to check out Effective C++ by Meyers

The super-simple version of using placement new is...

class A;
void* tmp_buff = get_mem_from_somewhere();
A* a = new(tmp_buff) a;

...use a...

a->~A();
put_mem_back(tmp_buff);

Thanks for the replay,

I was curios because I did this a few yeas ago, but I no longer remember how
:(
Right now I am using a form of the new operator for the same thing.

It seems that you can use:
((A*)tmp_buff)->__ctor();

and as you pointed out:
((A*)tmp_buff)->~A();

You need "placement new".

>((A*)tmp_buff)->__ctor();

That's totally non-standard, and there's no reason to use it.

If you really are the sort of evil-doer who wants to perpetrate
such things, have a look at the MFC source code for CArray class.
IIRC it does all sorts of nasty things like this :-)
