    - static global variable How many instance of the variable will be produced if I declared a static global variable in one header file, and two .c / .cpp files included the header file? Example as the following: <abc.h> static int abc = 1; ... <abc1.c> #include "abc.h" void ChkAbc1() { int* Addr = &abc; } ... <abc2.c> #include "abc.h" void ChkAbc2() { int* Addr = &abc; } ... One more question, if a static global variable declared in a .c / .cpp file, can I extern this variable on the header file? Example as the following: <abc.h> extern int abc; ... <abc.c> #include "abc.h" static int abc = 1; ... <main.c> #include "abc.h" void main() { int* Addr = &abc; } ...

    - Strange linker-problem (LNK1179) with a template-function Hello, I have defined a template-function in a header-file, which takes a pointer to a function and a parameter for that function as template-parameter (similiar to STL's for_each): template <class Fun, class Param> void for_each_radio(CSubWindows& subWindows, Fun fun, Param param) { for (int i = 0; i < subWindows.GetRadioCount(); ++i) { (subWindows.GetRadio(i)->*fun) (param); } } The template is 100% correct, I tested it...But the problem is, it only works if I use for_each_radio only once in my code. Else I get the linker error "LNK1179: Invalid or corrupt file: duplicate comdat ...for_each_radio..." It seems like the function will be instantiated twice with the same name because I don't use the /H and /Gy compiler options...How can I solve this horrible problem? of course there are include-guards in the header and I can't put in the code in a cpp (template!)...

    - 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: Create static library 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? And if they ar not - where to find the fix? --- With best wishes, Kirill. * ...chasing dreams... Tag: Create static library Tag: 228788

    - 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!

Consistently, the value 4313, that showed up in iteration 340, repeat itself in the 349th iteration ! If it would be a true random generator, and given that it is defined as returning type int, it would use one of the (primitive) generating polynomials of the 15th rank, such that it would guarantee not to repeat even once before exhausting all values between 1 and 32767, while 0 is not in the game (different seeds should only impact the order in which these 32767 numbers are generated (and possibly starting with different values)).

However, when I intend to integrate with code that supposedly should be supported (as to define a variable anywhere in a function), it does not let me it forces me to declare the variable at the beginning of the function. I've tried to look at the project settings to see what is that is configured, but I do not see anything that forces this app to use traditional C syntax (i.e. I checked the compiler switches). Can anybody there suggest what can be happening? Thanks, Carlos. Tag: Create static library Tag: 228670

    - convert character Hi, I hope the question is not too off-topic... Is there any function in VC7.1 or any SDK which... 1) ...converts a 8-bit char to the corresponding 16-bit unicode value, using some given codepage? 2) ...does the reverse when possible? for example, if I run charmap.exe I see "Euro sign", U+20AC (0x80) which is exactly what I need. -- The set of solutions is never empty. Two solutions together form a new problem. -- Mycroft Holmes Tag: Create static library Tag: 228660

    - VC7.1 - put debug info in .exe not .pdb In VC6, when building an debug .exe, the linker switch /pdb:none (combined with /debug and the /Z7 compile switch) put all the debug info into the .exe itself and no .pdb file was created I believe I may have read somewhere that this is no longer possible in VC7.1 i.e. when building a debug exe I am forced to have the debug info in a .pdb file. I have certainly been unable to manage it so far, I always end up with my debug info in a .pdb file despite trying many different compiler/linker switch combinations. Is it true that VC7.1 no longer supports this ? If not, what are the magic words in order get the debug info into the exe and not create a .pdb file Thank Andy Tag: Create static library Tag: 228658

    - what's the meaning of "car","cdr","cons" in tree's algorithm? Hi! I find a section of source code about binary tree's algorithm£¬I find the struct: typedef struct _BIN { void *car; /* address of <car> */ void *cdr; /* address of <cdr> */ } BIN; typedef struct _CELL { int tag; /* tag of <cell> */ /* 0: cons */ /* 1: atom */ union { BIN cons; U_CHAR *atom; } value; } CELL; there is "/* address of <car> */" & "/* address of <cdr> */" , but I don't know what's the meanning of "car" , "cdr" & "cons"? Thanks in advance! Tag: Create static library Tag: 228654

    - GlobalFree throws exception after CPrintDialog::DoModal() Hi! I'm initializing a CPrintDialog to display a previously selected printer. For this I allocate memory on the heap with GlobalAllo for the CPrintDialog::m_pd.hDevNames (and m_pd.hDevMode (same problem)). To the best of my knowlege I should use GlobalFree to clean up but after the call to CPrintDialog::DoModal() the memory i create with GlobalAlloc seems to get displaced or is deallocated. In debug mode a user breakpoint is called and I get a message saying: Invalid Address specified to RtlFreeHeap For now I have commented out calls to GlobalFree to make it work but i suppose this gives me a memory leak. Can anyone help out? / thanks in advance Anders Here's the code: // allocate a new DEVNAMES object on global heap int nSize = sizeDevNames + sizeName + sizeSpool + sizePort; HANDLE local_hDevNames = ::GlobalAlloc(GPTR, nSize) ; // allocate on heap LPDEVNAMES lpDevNames = (LPDEVNAMES)::GlobalLock(local_hDevNames); // lock it memset(lpDevNames, 0, nSize) ; // init to 0 // add the 3 strings to the end of the structure ... ::GlobalUnlock(local_hDevNames) ; // unlock CPrintDialog nDlg(true); nDlg.m_pd.hDevNames= lpDevNames; if(nDlg.DoModal() == IDOK) { ... } ::GlobalFree(local_hDevMode); // here's the error Tag: Create static library Tag: 228653

    - Is there a way to recall a constructor function of an already existing class object? Given the following class A and object instantiation Ai: class A { int d; public: A(int a=0) {d=a;}; }; A Ai; In order to reset Ai's data members, I thought simply to issue the following statement: Ai.A(); like calling any other public function member of A. But the compiler doesn't like it. Any elegant solution to accomplish it? In reality, my A's data members are many and its quite complicated, that is why I would like to reuse the constructor.

When creating a static library, VC++ 6 generates several .obj files and one
.lib file. Besides adding the header file of the library into the client
project, which other files should be also included into the client project
so that the class defined in the static library can be used by the client?
Thanks!

Nothing else, you only need the header files and the lib.

No extra files are needed, but you need to add the library to the linker
settings
of the client project

Project Settings-> Link, Object/library modules : add your lib there.
