    - help with member functions as callbacks Hello #include <iostream> #define CALL_MEMBER_FN(object,ptrToMember) ((object).*(ptrToMember)) class Fred; typedef int (Fred::*FredMemFn)(char x, float y); class Fred { private: FredMemFn m_fn; public: int f(char x, float y); int g(char x, float y); int h(char x, float y) { std::cout << "Fred's h()" << std::endl; return 0;} int i(char x, float y); void SetFN(FredMemFn f) { m_fn = f; } void carry() { CALL_MEMBER_FN(*this, m_fn)('x', 1); } }; class CMyFred : public Fred { public: int x(char a, float b) { std::cout << "MyFred's x()" << std::endl; } void test(); }; void CMyFred::test() { // this works SetFN(Fred::h); // this doesn't <-- how to make it work? w/o casting SetFN(x); } int main() { CMyFred f; f.test(); f.carry(); // calls Fred's m_fn() return 0; } How can I make this code work if I want class Fred/carry() to call handlers set in CMyFred ? If typedef int (Fred::*FredMemFn)(char x, float y) is a pointer to a Fred member function, won't a member function in CMyFred (subclass of Fred) with same signature be accepted? It seems that if I change the code in CMyFred::test() from: SetFN(x); to SetFn((FredMemFn)x); then the program compiles. Any way to tell it to accept w/o this typecast? On clc++ they reported to me that another compiler accepts the original code w/o complaints. Regards, Elias Tag: how can i get the mainboar ID and harddisk ID Tag: 228969

    - Assertion failure in dbgheap.c Hi all I've got a problem with the use of two classes I made. I made a thread class similar to the 'Thread' class in Java. I have a class for handling the thread (called CMMThread) and another one (called CMMThreadObject) as an interface (like the 'Runnable' interface in Java). I put both classes in a dll and try to use them from a normal .exe . When I derive a class from CMMThread everything works as expected, but when I derive a class from CMMThreadObject, create a CMMThread object with the object derived from CMMThreadObject passed in the constructor, I get an assertion failure when trying to destroy the object derived from CMMThreadObject, I get the assertion failure Here's the code of my classes (only relevant part): <code> CMMThreadObject::~CMMThreadObject() { if ( thread ) { delete thread; // --> call destructor of CMMThread thread = 0; } } CMMThread::CMMThread(CMMThreadObject * object) { this->object = object; id = 0; handle = 0; running = 0; exitcode = 0; } CMMThread::~CMMThread() { if ( object ) { object->thread = 0; object = 0; } if ( handle ) { int sts = CloseHandle(handle); handle = 0; } } // <-- error occurs when returning from here void CMMThread::Start(void) { if ( object ) { object->thread = this; handle = CreateThread(0,0,CMMThreadRunObject,object,0,&id); // handle = _beginthread(CMMThreadRunObject,0,object); } else { handle = CreateThread(0,0,CMMThreadRunThread,this,0,&id); // handle = _beginthread(CMMThreadRunThread,0,this); } } // BounceProc to start the thread with an associated object MMTHREADRESULT __stdcall CMMThreadRunObject(void * arg) { CMMThreadObject * object = (CMMThreadObject *)arg; MMTHREADRESULT result; object->thread->running = 1; result = object->Run(); object->thread->running = 0; // _endthread(); ExitThread(result); return result; } // BounceProc to start the thread (using a class derived from CMMThread) MMTHREADRESULT __stdcall CMMThreadRunThread(void * arg) { CMMThread * thread = (CMMThread *)arg; MMTHREADRESULT result; thread->running = 1; result = thread->Run(); thread->running = 0; // _endthread(); ExitThread(result); return result; } </code> And here's the code of my app using my classes: <code> class TestObject : public CMMThreadObject { public : MMTHREADRESULT Run(void); }; class TestThread : public CMMThread { public : MMTHREADRESULT Run(void); }; ... TestObject * object[5]; CMMThread * thread[5]; // Here I create 5 threads for ( i = 0; i < c; i++ ) { sprintf(threadname,"Thread #%d",i); object[i] = new TestObject(); thread[i] = new CMMThread(object[i]); thread[i]->Start(); printf("thread %d started\n",i); } // Here I wait for the threads to complete for ( i = 0; i < c; i++ ) { object[i]->Thread()->Wait(); } // Here I try to destroy all objects for ( i = 0; i < c; i++ ) { delete object[i]; // <-- Failure occurs here (indirectly) // 1st, the destructor of CMMThreadObject is called // which then destroys the thread object (see above) } </code> When returning from the destructor of CMMThread, I see the following assembler code (from where the error occurs): 10001265 mov eax,dword ptr [ebp+8] 10001268 and eax,1 1000126B test eax,eax 1000126D je CMMThread::`scalar deleting destructor'+3Bh (1000127b) 1000126F mov ecx,dword ptr [ebp-4] 10001272 push ecx 10001273 call operator delete (100022d6) 10001278 add esp,4 Inside the call of the 'operator delete', '_free_dbg' is called, which then calls '_free_dbg_lk' from dbgheap.c which then fails in the statement '_ASSERTE(_CrtIsValidHeapPointer(pUserData));' I can't see a reason for that. Both objects are created by my test application and I also try to destroy them from there. I tried many other combinations, like destroying the thread object inside a 'Destroy' method (delete this) or destroying the two objects inside the the test application (delete object[i] and delete thread[i]) but nothing helped. I also tried to use the _beginthread and _endthread functions from C++ (according to MSDN, this is the way to go for C++ programs). Can someone please help me to find a solution (maybe need to create my own 'operator new' and 'operator delete' methods?).

    - Process creation and the execution. I have one question regarding the process creation. I want to invoke a chield application from another console application. i.e. Virtually I could have code something like system("c:\\exe files\\myapp.exe") But the problem with this is dos command line interpreter does not accepth blanks inbetween. So I decided to go for ShellExecute() function. I want my parent process execution to suspend as soon as ShellExecute function invoke the chield application. But It seems by default ShellExecutes invoke the chield applicaiton in other thread and resum the parent one. Is there any way instruct ShellExecute to suspend the parent proecess execution until child process resumes ? Or is there any function in Windows to achieve the same job ?

    - std namespace and old code? I've returned to a perfectly working old project written with VC++2002 but now VC++2003 is rejecting the .h standard header files and demanding the std:: prefix before simple standard commands. Is there any way to get around this? What could have been a two-minute addition of a single feature is becoming a long rewrite of a vast expanse of code!

    - linking into a shared library Hello everybody I have a program which has 12 workspaces and each of them after successful compilation can build a seperate *.lib file. The documentation of this program says 'once all these files are compiled, link them into a library, or a shared library, or directly into your program.' I am not sure what has to be done and how. Can someone please tell me what is required to be done here? Should a single *.lib has to be created from all these 12 *.lib? How it can be done?

    - Bug when generating some inlined (intrisic) strcat in vc 7.1 This is very easy to reproduce, just compile the sample code below (C or C++, it doesn't matter) with /O2 or /Ox option. Just adding a #pragma function(strcat) or compiling with /O1 or /Od removes the bug. I didn't try other version of Visual C++ than the one from Visual Studio.NET 2003 Entreprise Edition (french version, from MDSN subscription). Conditions to make this bug happen: 1) an inlined strcat (intrisic) and 2) first parameter of the inlined strcat is a not-inlinable function call returning the destination string pointer and 3) second parameter of the inlined strcat isn't a literal constant string (the inlined strcat must have to do an inlined strlen on it, the optimizer musn't be able to find a constant length). // BEGINNING OF SAMPLE #define WIN32_LEAN_AND_MEAN #include <windows.h> #include <stdio.h> #include <string.h> // making the variables below global prevent optimizations that "hide" the bug char sz1[256] = "abc"; char sz2[] = ".ghi"; int main (int argc, char **argv) { // lstrcat (below) instead of a second strcat to prevent its inlinning, because // the lstrcat replaces a more complex function from a DLL of mine. // The code generated for the inlined strcat is realy very bad ! strcat(lstrcat(sz1, "def"), sz2); // sz1 is (far) large enough for that // should print "abcdef.ghi" but the lstrcat make an exception ! printf("%s\n", sz1); return 0; } // END OF SAMPLE The generated code (with my comments) is plainly wrong: _main PROC NEAR ; Line 15 ; THE INSTRUCTION BELOW APPEAR TOO SOON push OFFSET FLAT:??_C@_03BHEEIFFN@def?$AA@ ; push second parameter of lstrcat ("def") mov eax, OFFSET FLAT:_sz2 ; get second parameter of strcat ; THE INSTRUCTION BELOW APPEAR TOO SOON TOO push OFFSET FLAT:_sz1 ; push first parameter of lstrcat (sz1) ; inlined strlen(sz2) mov edx, eax $L20160: mov cl, BYTE PTR [eax] inc eax test cl, cl jne SHORT $L20160 ; OOPS, WRONG ! backup ebx/esi AFTER pushing parameters for lstrcat and before ; calling lstrcat ! push ebx push esi sub eax, edx ; end of the inlined strlen(sz2) ; STILL WRONG ! same reason as above push edi ;THIS (WAS ABOVE) SHOULD BE HERE: push OFFSET FLAT:??_C@_03BHEEIFFN@def?$AA@ mov esi, edx ; backup strlen(sz2) value ;THIS (WAS ABOVE) SHOULD BE HERE: push OFFSET FLAT:_sz1 mov ebx, eax ; backup sz2 pointer ; lstrcat below is COMPLETELY LOST with the random values pushed from edi and esi ! ; => exception call DWORD PTR __imp__lstrcatA@8 ; inlined strcat, skip existing chars in the (never) returned pointer to sz1 from lstrcat dec eax $L20161: mov cl, BYTE PTR [eax+1] inc eax test cl, cl jne SHORT $L20161 ; and copy sz2 at the end of sz1 mov ecx, ebx shr ecx, 2 mov edi, eax rep movsd mov ecx, ebx and ecx, 3 ; Line 17 push OFFSET FLAT:_sz1 push OFFSET FLAT:??_C@_03OFAPEBGM@?$CFs?6?$AA@ rep movsb call _printf add esp, 8 pop edi pop esi ; Line 18 xor eax, eax pop ebx ; Line 19 ret 0 _main ENDP Tag: how can i get the mainboar ID and harddisk ID Tag: 228864

    - convert character again Hi again, some day ago I asked how to convert a char and get its unicode value. The proposed solution was to call WideCharToMultiByte/MultiByteToWideChar Now, I'd rather not call the APIs directly, so I thought another solution: the following works perfectly. typedef wchar_t unicode_t; inline unicode_t widen(const char c) { return std::use_facet< std::ctype<wchar_t> > ( std::locale("") ).widen( c ); } My questions: 1) does it work by chance or... by design? is a wchar_t assumed large enough to hold a unicode value? It looks like there ARE some unicode chars whose code is > FFFF if there's a tight relation between wchar_t and unicode values, I think 'ctype::widen' may be assumed to convert to unicode, isn't it? 2) I read in MSDN there's a UTF-8 codepage named "65001". does it mean that std::use_facet< std::ctype<wchar_t> > ( std::locale(".65001") ).widen is able to read UTF-8 and convert to unicode? -- The set of solutions is never empty. Two solutions together form a new problem. -- Mycroft Holmes Tag: how can i get the mainboar ID and harddisk ID Tag: 228857

    - stuck with what looks like a compiler bug in VS.NET 2003 vs VS.NET 2002 This is going to be a little vague I'm afraid as it's hard for me to provide explicit details without a vast quantity of extra information. I've recently changed compiler from .NET 2002 to .NET 2003. I have a fairly complicated application, which is an ISAPI extension that relies on several other rather large projects (Xalan, Xerces, ICU, boost). At some point, i'm at the bottom of a pretty deep call stack, and I throw an exception which travels up a lot of it. It seems that in one particular module, a couple of the functions don't manage to unwind the call stack properly -- it always crashes in either of these two functions during the unwind sequence. It's 100% reproducible with .NET 2003 and 100% not reproducible with .NET 2002, and depending on how I've been tinkering with the code, always crashes in the same place. I've tried sprinkling some extra try () { } catch (...) { throw; } blocks around various parts of these functions. The result is that I can make the problem go away, presumably by generating different unwind code. Oh, and this only happens with a release build. Normally I'd claim responsibility for mashing memory rather than pointing at the compiler, but in the case, the application (and those things that it relies on) have been proved to be very stable. I can also make this happen with a wide variety of initial conditions (effectively doing things that would drastically change the pattern of memory allocations up to that point), pageheap /full doesn't spot anything, and if I _don't_ throw the exception, then things all work as expected, even to the point of being able to conduct stress tests that previously passed. I realise that this is a bit of a long shot, but if anyone could offer any advice on what to try or look for to be certain as to what is going on that would be great. The application is open source, so if anyone has a great deal of spare time then it should be possible to recreate it locally. I'm out of ideas other than reading the compiler generated assembly at the moment (which isn't an easy task as my asm is a bit rusty these days). If it comes to it, I guess I'll have to drop back a compiler version, which would be a pity. Thanks, Mark Tag: how can i get the mainboar ID and harddisk ID Tag: 228791

    - is STL in msvc 6.0 (sp5) thread safe Hi there! We have app server written in C++ (stl is used a lot). And we use Visual C++ 6.0 compliler to built it. App is not stable when it is heavy loaded. It eather crashes or some static data in it becomes corrupted (so server stops doing his duties). We put some stuff from server into a test and with a lot of threads doing subset of usual servers work. And test crashes within minute or so. 40 threads are intensively doing allocation, populating and freeing containers such as std::map and std::set. Threads write only to their own (private) containers and there are some shared containers that are only read (via find method). So the question is: are stl containers such as std::map and std::set in VC6.0 thread safe in mentioned manner?

    - loading bitmaps from files Hello all, I'm writing a programme which needs to load bitmap files (*.bmp) from disk and then access the raw pixel data. I'd like an easy way to get that raw data as one plane, 32 bits per pixel. Right now I'm using LoadImage() to get the file and then two calls to GetDIBits(). The first call is to get the BITMAPINFO structure data so I know how big a buffer to allocate for the pixel data, and the second call actually gets the raw data. hbmp = (HBITMAP)::LoadImage(NULL, lpszFile, IMAGE_BITMAP, 0, 0, LR_LOADFROMFILE); memset(&bmi, 0, sizeof(BITMAPINFO)); bmi.bmiHeader.biSize = sizeof(bmi.bmiHeader); rc = ::GetDIBits(::GetDC(NULL), hbmp, 0, 0, NULL, &bmi, DIB_RGB_COLORS); m_pclrBits = (COLORREF *)calloc(bmi.bmiHeader.biWidth * bmi.bmiHeader.biHeight, sizeof(COLORREF)); rc = ::GetDIBits(::GetDC(NULL), hbmp, 0, bmi.bmiHeader.biHeight, m_pclrBits, &bmi, DIB_RGB_COLORS); Currently my programme just assumes that the raw pixel data will always be 32bpp with only one plane, but I just don't know if that is the case. ::GetDC(NULL) returns the root (desktop) window, which on my computer is 32bpp, but it might not be on a different machine and for all I know GetDIBits() might "translate" the raw data into however many bits/pixel and planes the root window is using. Would I be better off using ::GetBitmapBits even though the MSDN library says that is an obsolute function? Is there a way to ensure that the raw data is _always_ 32bpp and in a single plane? I'd rather not have to write code to take number of colour planes, bits per pixel and the colour table and translate "by hand" the raw data into 32bpp. Too many variations/combinations, too much wasting time. :-P I'd prefer to write all the code myself, rather than downloading some third-part toolkit which woud probably have more function than I need. Thanks in advance. P.s. Is there no function to write bitmap data to a *.bmp file? I found the basic structure of a *.bmp file in the MSDN library help files, so if I had to I could hack up a *.bmp file writer, but I'd rather not. Is there a SaveImage() companion to LoadImage() that I could just pass an HBITMAP handle to? -- Cory Albrecht http://cory.doesntexist.com/ "Star Trekkin' across the universe!

And what do you do if a mainboard or hard drive must be replaced? A better
bet would be to use the Crypto API or some other 3rd party
