    - Why does this compile with VC++? class A { public: A(int) { } private: A(const A &); A &operator=(const A &); }; A foo() { return A(0); } void bar() { A a = foo(); } Even though the compiler may optimize out the call to the copy constructor, it should still respect the fact that it is declared private. From the C++ standard: "Even when the creation of the temporary object is avoided, all the semantic restrictions must be respected as if the temporary object was created."

    - MS Visual C++ Professional Edition/ Academic Version I am running Windows XP, Home Edition 5.1 (sp2) on a GenuineIntel Processor (512 MHz, 256 MB RAM). Just when I though I understood (wishful thinking) the myriad of flavors of MS Visual C++, version 6, I now see MSVC++ Professional Edition - Academic Version. My question is, what is the academic version of the professional edition? Does it lack some of the functionality of the regular professional edition. I have been messing with the Express Edition and am wanting to avoid getting anything similar. I like the MFC AppWizard in the Professional (and I think standard) edition. You make a menu item and then R-Click, choose ClassWizard and bingo - you're adding code for your event handler. With the Express Edition, you right click and there is nothing related to an event handler. Just a lot of stuff to make the item prettier. I eventually got an event handler but it was in the .h file. To sum it up, if I want the AppWizard capability (and MFC) associated with the professional edition, would the academic version work? Many thanks in advance, Peter.

    - How to catch this error Access Violation I have a crash; I know that crash is in the following code 0012d300 12d75f49 OLEAUT32!VariantClear+0xb1 It is because the VariantClear tries to release a COM Object that is not long valid.

They show up on a google search, but they only link to "Content not found" errors on msdn.microsoft.com. If I go to the msdnmag search page http://msdn.microsoft.com/msdnmag/find/default.aspx? and look for "Schmidt" by author or "Deep C++" by title, I get nothing.

    - Want to create a function which returns a value obtained from a callback function Hello I want to write a C++ function which returns a Windows handle. I need to call a callback function to find the Window. The specific function is EnumChildWindows. As the final parameter of EnumChildWindows I can pass a pointer back to my class. so I can access class functions ok. I thought that I could have a member variable in the class which is an HWND. Then the this variable could be updated by EnumChildWindows if a window handle is found. then when the function returns I just take the value in the variable as the first found windows handle. I suppose that would work but it doesn't feel so elegant. Has anyone got any better ideas? Angus Tag: bison and flex in visual stdio 2005 Tag: 274417

    - Variable arguments & class objects... what's the "type" When a call to a function with variable arguments is made, such as any of the printf() family of functions, all of the actual parameters passed after the last formally defined argument get pushed on the stack after going thru some sort of type casting operation. Integral data types appear to all get cast into a numeric value equal to the machine architecture's native word size [e.g. 32-bits or 64-bits]. Likewise, pointer data values get treated the same way. What I'm interested in knowing for certain is how MS Visual C/C++ handles instances of class objects that are passed in this way. It appears that the address of the class object is what gets pushed on the stack, but what I can't tell is whether or not the compiler does this unconditionally or if it actually uses some sort of implicit conversion operator that by default uses the value of "this". If there is a data type that the class is being implicitly cast to, then what I really want to do is to provide my own overload of that conversion operator so that I can have something else, such as maybe a string buffer which the address of gets used instead of the class object's own address. Any ideas?

However, I never call CHeaderCtrl::Create() because the creation is done automatically when the CListView is created (so the code is hidden from a novice like me).

The problenm is that LoadLibrary will only accept a fully qualified path to the DLL. A relative path returns error 126 (module not found) and a null HINSTANCE. Strangely a full path sets GetLastError() to 6 which is invlalid handle although all GetProcAddress calls work and the DLL functions ok. I am using MS C++ 7 on Windows XP Service Pack 2. Any ideas ?

    - Changing file names in VS projects. Greetings, I have inherited a workspace with 2 projects in it. Looking at the directory I see that the .cpp files for the first created project are in the workspace directory and the .cpp files for the 2nd project are in a sub-folder. In the workspace and the new project folder there is a file named UsbHid.cpp. This does not cause a problem for VS but to avoid confusion for me and others I would like to rename the file in the sub-folder. It is more difficult than I thought. I can change the name by external means but the project clings to the old name. Is there a clean way to do this? I don't immediately see a way to delete files and/or projects. Thanx, jh Tag: bison and flex in visual stdio 2005 Tag: 274362

    - static variables discarded by the VS.NET2003 linker Hi Everyone, I found a thread on that topic posted year 2004 but not satisfied with the information there. So I decided to raise that issue once again. In general the problem with VS.NET 2003 linker is that it will discard an object file containing definitions of global variables of any type/ class if nothing else in this file is referenced by other files in the project. Now I have the following case. In given source file I have definitions of several global variables that in contructor register itself in another global container object. Later in code any of these variables would be accessed via that global container. But what actually happens is that the linker decides to discard the object files and instances of these global variables are never created and registered in the container. I am not sure what should be the correct behaviour of the linker in that case but could anyone let me know how to overcome that problem and make the linker to include the needed object files without forcing it to include any object files from given library even if not referenced at all? Can we say that in my case objects are not referenced at all since even if they are not referenced directly still it is possible to be reference via the container object? Many thanks in advance! Best regards, Boris. Tag: bison and flex in visual stdio 2005 Tag: 274341

    - Why on earth are there no VC++ 2005 SP1 redists on downloads.microsoft.com? I mean, seriously, what gives? If you run a program needing SP1 on a machine with only the RTM redist you get what is probably one of the dumbest, most unhelpful, stupidest error messages imaginable. It's TOTALLY non-obvious that there's a version mismatch; the configuration information is not incorrect, it's just unfulfilled. depends even more helpfully suggests that the manifest may be corrupt. So why the hell aren't the redists on the website? The redists you have at the moment are useless for SP1 apps; what the hell's the point of even having them? The whole SxS is such a brain-damaged sorry-ass system. And how about fixing it so that the error messages aren't so totally worthless?

    - Asking for trouble with incomplete types? Hi, I am trying to reduce the complexity of a set of classes I made a couple of years ago, what equates to a set of trees, for which I want to use std::list and avoid having to use direct pointers anywhere. I wish to have a class contain a list of itself, as so: class B; class A { public: std::list<B> List; typedef std::list<B>::iterator iterator; iterator begin() { return List.begin(); } }; class B { public: A m_a; }; My question is, provided I ensure there is no in class A referencing direct instances of B, can I be fairly certain im not launching into a world of c++ driven pain, for example no: class A { ... B GetSomething(); }; I expect that as long as thing that call items such as copy constructors or -> / * operators of list<B>::iterator are in cpp files there should be no issue. Could anyone tell me different? Regards, -- - Mark Randall http://www.temporal-solutions.co.uk http://www.awportals.com Tag: bison and flex in visual stdio 2005 Tag: 274322

    - Odd behavior of #if preprocessor directive Hello, Can somebody explain what am I doing wrong or why #if preprocessor directive shows this odd behavior. I am using Visual Studio 2003. I have following code: ============================= #define MY_MACRO MACRO_B #if MY_MACRO==MACRO_A # define MY_PRINT printf ("MACRO_A\n") #elif MY_MACRO==MACRO_B # define MY_PRINT printf ("MACRO_B\n") #else # define MY_PRINT printf ("MACRO_C\n") #endif extern void print_my_line ( ) { MY_PRINT ; } ============================= I was expecting that in my function print_my_line, MY_PRINT would expand to print "MACRO_B". However when I run this code through preprocessor, I get following: ============================= extern void print_my_line ( ) { printf ("MACRO_A\n") ; } ============================= This happens regardless if I define MY_MACRO to be MACRO_B or MACRO_C or anything else. it appears that "#if MY_MACRO==MACRO_A" always evaluates to TRUE regardless what the definition of MY_MACRO is. Is there any explanation why preprocessor behaves like this. Am I missing some flags or settings? Thanks and Regards Yogi Watcher Tag: bison and flex in visual stdio 2005 Tag: 274317

    - .NET Socket-ReConnection Error-Connecting To UnWorking Server Sock Hello, First of all I wish you a good day. My help request is about .NET asynchrounus socket communication. I have developed Server-Client Windows Forms .NET applications in VC++ .NET v2003. I have several problems re-establishin connection between peers. Below are my problem cases after closing of the first successfull communication; #1) I re-start the Server to accept connection requests. While it is waiting, I run the Client. It is connecting to server socket and waits for the data communication. But at this time, my server program is still waiting at "BeginAccept". Nothing changes at its status. #2) I re-start the Server to accept connection requests. While it is waiting, I run the Client. It gives 10061 WSAECONNREFUSED (Connection refused by host) #3) After first successful communication closing, I start the Client to connect to server 2-4 seconds later. It connects to a server socket however my server socket program is not started to accept connection requests at this time. Then, Client program waits for data communication. I checked the working TCP sockets with "netstat -n -o 2" command. After the closing of the first successfull communication, first server socket's status either TIME_WAIT and several seconds later CLOSE_WAIT, or when it TIME_WAIT, new connection is being set with same server IP:PORT with clietn socket (problems at #1 and #3) I shutdown and close my sockets using the same commands. Below is the function, that is same for both; static Socket *m_ServerSocket = NULL; // *m_ClientSocket = NULL; System::Void mf_Shutdown_And_Close() { try { if (m_ServerSocket != NULL) { if ( m_ServerSocket->Connected ) { m_ServerSocket->Shutdown(SocketShutdown::Both); Thread::Sleep(250); } m_ServerSocket->Close(); m_ServerSocket = NULL; Thread::Sleep(500); mf_ChangeButtonStatusTo( ConnStatus::CONNECT ); } } catch(Exception *exp) { // Programda hata durumunu gÃ¶ster } } Below are the options of my sockets Server Socket: SetSocketOption(..., SocketOptionName::ReuseAddress, true); SetSocketOption(..., SocketOptionName::KeepAlive, true); SetSocketOption(..., SocketOptionName::DontLinger, true); and Client Socket: SetSocketOption(..., SocketOptionName::DontLinger, true ); Previously, I developed similar Server-Client programs using native C++ and blocking codes. I didnot faced with this kind of problems. Why Server socket is not closing totally after succesfull Shutdown() and Close() commands? I put Thread::Sleep(..) to let the program give time to system to release resources. Even Using GC::Collect() did not useful. Thank you very much in advance for your helps.

    - const oddity in decorated names If I declare the functions void foo(int bar[]) void bar(int * bar) then I expect them to behave the same way - and indeed they do in most cases. I have give these functions these (admittedly meeningless) implementation: __declspec(dllexport) void foo(int bar[]) { bar = NULL; } __declspec(dllexport) void bar(int * bar) { bar = NULL; } The program compiles. If I look at the decorated names of the exported names in the dll they aren't the same though. foo gets a decorated names that indicates that it was declared as void foo(int * const bar). But since the program above compiled that is obviously not the case. I'll have admit that the difference between "int *" and "int * const" in a function argument is irrelevant to the caller of the function, but is there a reason for this oddity, or is this just a mistake?

    - Visual Studio 2005 include file error I have ported a 32 bit module to 64 bit. It does database and e-mail, and requires the inclusion of mapi and sql header files. These header files are pulled in from the platform SDK inclusion directory of Visual Studio 2005. So, Visual Studio 2005 has the following: MAPIDEFS.H declares: typedef ULONG BOOKMARK; SQLTYPES.H declares: typedef SQLULEN BOOKMARK; This worked fine in 32 bit because SQLULEN was typed as unsigned long. Under 64 bit, it is typed as UINT64. Of course, my module will not compile, without error, as a 64 bit application because of the redefinition of BOOKMARK Can someone suggest an elegant way of getting around this use of the same type name that is based on a different type? Either I'm missing something obvious/easy, or this change wasn't thought out properly. Thanks, Robert. Tag: bison and flex in visual stdio 2005 Tag: 274293

    - How to track down BSTR allocation problems? Hi! I experience constant program crashes. I know it is very likely due to wrong usage of COM task heap (CoTaskMemAlloc/SysAllocString API) but cannot track the source of a problem directly at the point of a crash -- it crashes in SysFreeString on an already released (elsewhere) memory. Putting some debugging effort in this reveals that at some (essentially random) point SysAllocString returns a block of memory already occupied by another BSTR. When the latter of corresponding SysFreeString calls is made, the program crashes. I have source files at hand, but there is too much of code to look with bare eyes... so I'm stuck. Can one recommend any tool or technique to track down such BSTR allocation errors? Thanks. Alex Shulgin Tag: bison and flex in visual stdio 2005 Tag: 274288

    - Detecting stack corruption Hello all, Our application hangs with 0% CPU usage. When I "Break All", I see a very short call stack for our main thread (much shorter than it should be) - only the top few entries are shown. My experience has always been that this inidctates stack corruption. I have directed the debugger to break as soon as an exception is thrown. This has been done for all exceptions, in particular "Stack memory corruption" under "Native run-time checks". However, this is not catching the problem. We have a very large application with many threads, so it's like hunting for a needle in a haystack. Furthermore, procurring BoundsChecker has been quashed from above. So, I'd like to solicit alternatives on how to track down the point at which the stack is first corrupted. Thanks, Dave Tag: bison and flex in visual stdio 2005 Tag: 274281

There are several ways of solving this sort of problem.

1. You can put your exe files in one of the directories where VC++ expects
to find them. For example:

C:\Program Files\Microsoft Visual Studio 8\VC\bin

2. You can put the full path to your exe file in your rules file.

3. You can add the directory where your bison executable files are to the
VC++ executable directories list. This is under the

Tools|Options|Projects & Solutions|VC++ Directories|

menu item.
