    - unexpected public symbol in .obj for inlined function Hello, usually the compiler generates no symbol in the symbol table for an inlined member. inline int DerivedClass::function() { return 0; } But this is not the case in the following sample. (See below). where a public (external) symbol is generated. A problem occurs when the above inline function is included in 2 independent .cpp files and both .obj files are linked together (e.q. into a dll). ======== ExportTst1.cpp ======= class BaseClass { public: virtual int function() { return 123; } }; class DerivedClass : public BaseClass { public: virtual inline int function(); }; template <class Base> class TemplClass : public DerivedClass { public: int callFunction(); static inline Base & BaseOf(TemplClass<Base> const &); static Base * b; }; template <class Base> Base * TemplClass<Base>::b = 0; template <class Base> int TemplClass<Base>::callFunction() { return BaseOf(*this).Base::function(); } template <class Base> inline Base & TemplClass<Base>::BaseOf(TemplClass<Base> const &) { return *b; } inline int DerivedClass::function() { return 0; } template TemplClass<DerivedClass>; =============================== to compile: cl -W4 -nologo -D__WINDOWS__ /LD -c ExportTst1.cpp dumpbin /SYMBOLS ExportTst1.obj in a VC++ 8.0 Session. Note : The Problem flushes when the last statement template TemplClass<DerivedClass>; is removed. But i need the explizit template instantation. The original code is splitted into multiple files (the inline function are in a .inl file, the template functions are in a .c file, the classes/templates in a .hpp and the templ. instance is a client.cpp file). any ideas? -- mit freundlichen Grüßen/best regards mario semo Tag: namespace std sort function not working Tag: 282679

    - Suggestions for a Rusty C++ Developer? Hi, I've been going mostly .NET and Java development for the past nine years, with the last five focused on C#. I'd like to get my feet wet a bit with Windows programming in C++, mainly to get a little more under the hood and possibly to do some Windows Mobile development, most of which seems to be geared around C++ (at least to do anything very useful). I took a semester of C++ ("Introduction to Programming in C++) in college in 1998 and did well. On a scale of one to ten, I'd consider myself probably an eight as far as C# skills go. Does anyone have any suggestions about refreshers/tutorials (on MSDN or otherwise) that I should check out? Something like "C++ for C# developers" :-) Thanks!

    - Using thread synchronization My scenario follows - one thread fills a circular buffer and some 5 other threads read the data. The other details follows- 1. All threads operate independently. 2. Certain minimum and maximum difference limit the reading index of any thread from the writing index. In other words, since the speed of all threads are not similar the logic should limit the read index from the write index by some minimum difference and also by some maximum one. 3. I uses critical sections to ensure exclusive access to the buffer and it works fine. 4. I still have to use some synchronization mechanizm that controls the indexing difference between read and write threads(as described in 2) but I can't do it with Critical Section alone. I'm stack with the question which and how mechanisms of thread synchronization should I use(events, semaphores etc...) Can someone advise pleas?

    - Using a Windows DLL in Delphi Hello! Sorry for the (kind off OT), but I'm trying to translate the headers for vssapi.dll to use the dll with Delphi. Almost everything is fine and dandy, but when trying to use "CreateVssBackupComponents", I see that the MSDN entry indicates that the function is exported as "CreateVssBackupComponentsInternal". This is true in the Vista version of the dll. In older versions (Xp and 2003) the funnction was exported as "?CreateVssBackupComponents@@YGJPAPAVIVssBackupComponents@@@Z" In vista the function is ALSo present with that name. Is it "safe" to use GetProcedure Address with that long name, seeing that the name has not changes in all three versions (only a new alias was added)? I know nobody can be 100% sure, but is this a safe guess? Why are there a lot of exported function in this dll with those unfriendly names? If not an API supposed to be clear?

In the following example, will the assignment A = A.Increment() work for all compilers ? #include <stdlib.h> class IntegerArray { public: IntegerArray(); IntegerArray(int length); IntegerArray(const IntegerArray & rhs); IntegerArray operator=(const IntegerArray & rhs); ~IntegerArray(); int GetLength() const; int GetInteger(int k) const; void SetInteger(int k,int entry); IntegerArray Increment() const; static int * intvec(int length); static void del_intvec(int * q,int length); private: int * itsInteger; // array of integers indexed from zero int itsLength; // length of array }; int main() { IntegerArray A(5); for (int j = 0; j < A.GetLength(); ++j) A.SetInteger(j,1); // is this guaranteed to work for all compilers ?

    - recognize .Net controls properly and get infos/styles/properties In a Win32 project Is there a way to get infos/styles/properties for .Net GUI controls ? When using Spy++ and pointing to a .Net Checkbox (WindowsForms10.BUTTON.app.0.378734a) it return no styles like BS_CHECKED, BS_RADIOBUTTON, BS_CHECKBOX,BS_GROUPBOX. My application is similar to Spy++ ...how can I know if the window WindowsForms10.BUTTON.app.0.378734a is a button, a checkbox or something else?? How can I know the button state (Checked or not checked) since there is no BS_CHECKED for a .NET control ??? When looking under the style tab of Spy++ for a .Net checkbox we can see a 0000000B style (unknown style)....Maybe this will point to a solution? Is Win32 is appropriate appropriate to do a ".Net" spy++ ?? Is a managed application will offers more information on .net controls? Thanks, i really need help on this.

    - Pimpl idiom without dynamic memory allocation Hello! I have just discovered a way to use the private implementation idiom (pimpl), without the overhead of dynamic memory allocation. For those of you who don't know what this is, Wikipedia has a nice article you can read. Anyway, I discovered that if you make all members in the implementation class mutable, you can in fact use this idiom without any "unnecessary" memory allocation. Here's a minimal example of the method: // In the header of your class called Line #include <string> class Line { public: Line(const std::string& name); const std::string& GetName() const; void SetName(const std::string& s); private: // Private implementation idiom: // all member variables are hidden in this class class LineImpl; const LineImpl& m_pimpl; // normally a non-const pointer }; // and in your implementation file: #include "Line.h" // Here we define the class with the member variables class Line::LineImpl { public: LineImpl(const std::string& s) : m_s(s) {} // all methods need to be const here const std::string& GetName() const { return m_s; } void SetName(const std::string& s) const { m_s = s; } private: mutable std::string m_s; // the trick! all members are mutable }; // create the pimpl instance without using new Line::Line(const std::string& s) : m_pimpl(LineImpl(s)) {} // forward all member functions to the private implementation const std::string& Line::GetName() const { return m_pimpl.GetName(); } void Line::SetName(const std::string& s) { m_pimpl.SetName(s); } Ok experts, what do you all think? This method sacrifies const-correctness for some extra speed. Is it worth it? -- Daniel Tag: namespace std sort function not working Tag: 282592

    - Winsock select timeout Hi, i'm communicating with more than 40 serial devices connected thru' an serial hub. the pc has to communicate thru' UDP to the serial hub. since the response is quite sensitve, ( the application has to timeout within 100msec) we are using "select" call with timeout. There are around 100 threads that are parallely polling all the 40 devices on the serial hub. I noticed that the select call is timingout i.e. returning 0 eventhough there is socket in the buffer..does this mean that the timer got expired when that thread is in the sleep state (i.e. some other thread is running) and later when the thread resumes, it is just returning the previous state... I'm running this application on a 2.66G Pentium PC..will the context switching be an issue at all here. i dont see this problem if the number of threads is reduced...,meaning less context switching. thanks Tag: namespace std sort function not working Tag: 282579

    - A solution to warning C4251 - class needs to have dll-interface...? The following piece of code usually triggers warning C4251: 'MyClass::m_object' : class 'ThirdPartyTemplate<T>' needs to have dll-interface to be used by clients of class 'MyClass': template <typename T> class ThirdPartyTemplate { public: // Constructor. ThirdPartyTemplate() {} }; class __declspec(dllexport) MyClass { ThirdPartyTemplate<int> m_object; // warning C4251! }; Is there really anything wrong about it? Here at LKEB (www.lkeb.nl), we often get this kind of warning, when using Boost or STL. Now it appears that one can get rid of the warning, by wrapping the ThirdPartyTemplate<int> object inside a simple struct: struct WrapperStruct { ThirdPartyTemplate<int> wrappedObject; }; class __declspec(dllexport) MyClassWithoutWarning { WrapperStruct m_wrapper; // No warning! :-) }; Does this approach really solve the problem, or does it only hide the message?

    - __forceinline and SSE bug in VS2005? At the bottom of this message is an example of what I believe is a bug in the behavior of __forceinline when used with SSE intrinsics in Visual Studio 2005. The summary is it seems that when __forceinline is used on functions that contain SSE intrinsics, the functions are not inlined after a very small depth (something under 10 levels of functions). If __forceinline is replaced with __inline, the functions are all inlined. From what I've read, there is no way __forceinline should cause less inlining than __inline, but that's the behavior I'm seeing. Also, if the SSE intrinsics are replaced with regular C, the problem goes away as well. I know the functions don't get inlined by warning 4714 which gets raised on level 4 (not level 1 as MSDN seems to suggest), and by examining the assembly which clearly shows function calls. In the code below, the template parameter to the inlinetest function determines how many levels of function calls there are before the call to vset, which contains the SSE intrinsics. On my system, only very small numbers (around 5) will successfully be inlined - there's some ambiguity because the exact value has changed a few times and I'm not sure why. Replacing __forceinline with __inline or changing vset to not use intrinsics successfully inlines for much larger numbers (I've tested with 100). If anyone has any input on this problem - something I'm doing wrong or ways to proceed, I'd appreciate it very much. Thanks, -stephen diverdi -stephen.diverdi@gmail.com #include <stdio.h> #include <intrin.h> #define FORCEINLINE __forceinline FORCEINLINE void vset ( float * const _a, float x ) { #if 1 __m128 &a = *( __m128 * )_a; a = _mm_set1_ps( x ); #else for( int i = 0 ; i < 4 ; ++i ) _a[ i ] = x; #endif } template < int N > FORCEINLINE void inlinetest ( float * const a, int i ) { return inlinetest< N - 1 >( a, i + 1 ); } template < > FORCEINLINE void inlinetest< 1 > ( float * const a, int i ) { vset( a, ( float )i ); } int main () { float a[ 4 ]; inlinetest< 100 >( a, 0 ); fprintf( stderr, "%f\n", a[ 0 ] ); getc( stdin ); return 0; } Tag: namespace std sort function not working Tag: 282544

    - Loading mulitple versions of a DLL Hi all I have a dll, the source code of which is in C++. I want to be able to load two versions of the dll at the same time. The second version of the dll has some changes to the C++ code. I know that Windows does not allow loading mulitple versions of dlls with the same name, so is there a work around? I know that the 'hacky' way to get around this is to change the name of the dll. But I do not want to do this. I was thinking of using assemblies, but I am not sure how to create one.

    - Removing 1 character from the end of file using file streams Using std::ofstream (std::fstream, or std::filebuf), is there a way just to remove one character from the end of file (trailing '\n', for example) without copying it into a new file? Thank you. Tag: namespace std sort function not working Tag: 282470

    - Its been a long time! Hello to all! I don't know if any of you guys remember me, I sure remember some of you. And you were great help on the questions that I posted on this newsgroup a year and a half ago. I was the fellow reading the petzold book and testing its programs in VC++! I got to the point where I was coding, classes, structures, objects and using API functions within VC++ (Fun stuff!). Bummer I had to put all that aside to carry on with electronics and processors which I programmed in C since this was a priority to my project. As you may guess, after a year and a half without touching VC++ I am quite rusty but would probably take me a a month or two of review and I would probably be up to par from where I left off. I have posted this question about two years ago, and since technology evolves every day, I figure I would ask it again in this post. At this point should I continue with VC++ (this would mean reviewing all that I had leanrt plus learning new stuff like STL and the rest of the 800 pages in Petzold's book) or jump straight into .NET?

    - A more serious bug MSVC has some more problems with covariance. This one is much more of a showstopper than my previous bug. The following code compiles without warning on Comeau and g++. template<class T> class M; struct V { virtual V *vf(); }; struct A : virtual V { A *vf(); }; struct B : virtual V { B *vf(); }; struct D : A, B { D *vf() = 0; }; In Visual Studio 2005, it gives: error C2250: 'D' : ambiguous inheritance of 'A *V::vf(void)' Tag: namespace std sort function not working Tag: 282463

    - Hidden overloaded operator in multiple inheritance All, I found in multiple inheritance only the first base class's overloaded operators are visible. My overloaded operators has different signatures in the different base classes. They are not ambiguous. 'using operator..' statements can bring them back. Please see my minimal example below. I'd like to know if it is a bug or a feature. Thanks for your help, Tamas #include <iostream> #include <string> template <class Parent> class basei { public: int bi; int operator + (int i) { bi += i; std::cout << "basei::operator+ : " << bi << std::endl; return bi; } Parent& operator << (int i) { bi += i; std::cout << "basei::operator<< : " << bi << std::endl; return (Parent&)*this; } }; template <class Parent> class bases { public: std::string bs; std::string operator + (std::string s) { bs += s; std::cout << "bases::operator+ : " << bs << std::endl; return bs; } Parent& operator << (std::string s) { bs += s; std::cout << "bases::operator<< : " << bs << std::endl; return (Parent&)*this; } }; class comp1 : public basei<comp1>, public bases<comp1> { }; class comp2 : public bases<comp1>, public basei<comp1> { }; class comp3 : public basei<comp1>, public bases<comp1> { public: using basei::operator+; using basei::operator<<; using bases::operator+; using bases::operator<<; }; int main(int argc, char* argv[]) { std::string s; int i = 0; comp1 c1; c1.bi = 0; c1 << 1; // c1 << std::string ("hello"); // C2679 i = c1 + 1; // s = c1 + std::string (" world!"); // C2679 comp2 c2; c2.bi = 0; // c2 << 1; // C2679 c2 << std::string ("hello"); // i = c2 + 1; // C2679 s = c2 + std::string (" world!"); comp3 c3; // all good c3.bi = 0; c3 << 1; c3 << std::string ("hello"); i = c3 + 1; s = c3 + std::string (" world!"); return 0; } Tag: namespace std sort function not working Tag: 282431

    - IJolietDiscMaster->AddData returning STG_E_INVALIDFUNCTION Hi there, I am attempting to add a previously created IStorage container to an IJolietDiscMaster interface, although the file appears to have been created correctly and no errors were returned during it's creation, nor the streams that were added to it, unfortunately it returns STG_E_INVALIDFUNCTION. Could this be due to the way that I have created the streams? or not closed them correctly after adding data? Many thanks in advance as any help on this would be fantastic. Nick. BTW, this is being asked in this group as the device.drivers group isn't yielding any replies. Tag: namespace std sort function not working Tag: 282419

    - how to maximize reusability? Hello, I wonder what are the general methods to reuse a class component as much as possible? Like the case I showed you guys a few days ago class CPerson : public CPathFinder { }; class CSupervisor : public CPerson { }; I'd like to declare and define once for one single method... Some behaviours of classes are common, but don't know if I should put it in the base class or derived class.... For example: class CPathFinder { Render() }; Render() is used in CPerson and CSupervisor. But Render() in CPathFinder doesn't make sense cos it is not a tangiable object at all. How do I do classifications and encapsulations here? also if I put render in CPerson, Do all classes derived from CPerson needn't to declare and define the same method again? That should be what is meant by "reusable"? No??? Thanks Jack Tag: namespace std sort function not working Tag: 282401

    - VC++ Cursor mask problem on windows vista Hi Guys! I've built a test application in VC++ 6.0 which runs on windows XP. It is a just a simple mfc dialog app, which changes the cursor image using cur file. The code is: BOOL CProjectDlg::OnSetCursor(CWnd* pWnd, UINT nHitTest, UINT message) { // TODO: Add your message handler code here and/or call default m_hCurPenBlue = LoadCursor(AfxGetResourceHandle(), MAKEINTRESOURCE(IDC_CURSOR1)); ::SetCursor(m_hCurPenBlue); return TRUE; } The image is composed of a green mask, transparent on XP. While in XP the cursor has transparency over the dialog, running the same application in windows vista creates a black rectangle surrounding the cursor'ss image (It is not transparent any more). Do you know how to solve this (So the margin will be transparent on vista) Thanks, Ron Tag: namespace std sort function not working Tag: 282393

    - Calling convention ( __stdcall, __cdecl ) and DLLs I declared and defined two functions in a simple DLL, (with no DllEntry) as follows: EXPORT void __stdcall Func1(void); EXPORT void __cdecl Func2(void); Then, from another program I loaded this DLL using LoadLibrary, which succeded. Then, I used GetProcAddress twice to get pointers to these two funcs in the DLL. The GetProcAddress failed on the __stdcall type, while the other func I was able to invoke. Why is this so?

    - Capturing stdout from a started process... Hello, My setup is as follows: WinXP Pro, VS2005 Pro. I would like to start a process from within my C/C++ application, then capture that process's stdout into a file. I've been able to do it completely successfully using the library system function, that is: system("MyProcess.exe > someFile") However, my process opens up a command window when it runs, which is really distracting if I'm doing something else at the time. Instead, I simply want the process to run "unnoticed" but still be able to capture its output. I originally tried this in C#, which does provide facilities for doing exactly what I want along with MSDN example code to do it. The only problem is that either .NET is buggy in this regard, the sample code is flakey, or I am simply too dumb to use it. In any case, while it does work most of the time, it often misses the last line output by the process, even though I do wait for the process to end. So, I decided to go back to the old reliable of C/C++ to see if I could do it. Any ideas? Thanks, Ray Mitchell Tag: namespace std sort function not working Tag: 282296

In addition to `std::sort' you can use CRT `qsort' function:
