    - How to get code page from current language input method? Hi there, In my application, I need to get the code page for current IME device. For example, if user selected Chinese in language bar, and keyed in Chinese characters, I need to get code page 936 so I could translate the got key code, which is in unicode. into double byte character set. And if user uses Polish input method, my application should get 1250 as the code page. I am using _getmbcp() to get code page for current locale, but not accurate if the locale is English, but user is inputting other languages. Any idea how to get the code page? Thanks lot, Tag: create firewall interface "INetFwMgr interface" using CoCreateInstance failed on window server 2003 Tag: 282550

    - 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? Kind regards, -- Niels Dekker http://www.xs4all.nl/~nd/dekkerware Scientific programmer at LKEB, Leiden University Medical Center Tag: create firewall interface "INetFwMgr interface" using CoCreateInstance failed on window server 2003 Tag: 282546

    - __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: create firewall interface "INetFwMgr interface" using CoCreateInstance failed on window server 2003 Tag: 282544

    - typeid comparision does not work inside macro I have two functions return a type_info. I used them to see if a class is of a specifed type. const type_info& MyOtherClass::desc() {return typeid( MyOtherClass() );}; and /*static*/const type_info& MyOtherClass::isA() const {return typeid(*this);} If i put them in the code straight up it works. I find that a class is of the same knd as itself. But if i put them in a macro the two return different typeIds for the same class. it worked perfect in VS.net (2002). What im i missing?? I can supply a minimal project to show my problem. /Matt Tag: create firewall interface "INetFwMgr interface" using CoCreateInstance failed on window server 2003 Tag: 282541

    - 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. Does anyone know how to use assemblies or is there something better?

    - vs 8 bug ? Hi Forum, I have some disassembly to post which I think indicates a bug ... if not, then hopefully one of the gurus here can tell me what I'm doing wrong ... The scenario here is a .exe making a call to a __declspec( dllexport ) declared c function ... both projects are configured for _cdecl linkage ... What follows are two dissambly blocks, the first with the ** alleged ** bug, and the second with what seems to ** fix ** the alleged bug ... ------------------------ "bad" code block ------------------------------------------ pApuUpdateHWclock(fCurrentSimulationTime); 00401266 83 EC 08 sub esp,8 00401269 DD 45 A8 fld qword ptr [ebp-58h] 0040126C DD 1C 24 fstp qword ptr [esp] 0040126F FF 15 E8 D4 47 00 call dword ptr [_pApuUpdateHWclock (47D4E8h)] // __asm nop _pApuFubar(x); 00401275 DD 45 E0 fld qword ptr [ebp-20h] 00401278 DD 1C 24 fstp qword ptr [esp] . . . --------------------------------"good" code block -------------------- pApuUpdateHWclock(fCurrentSimulationTime); 00401266 83 EC 08 sub esp,8 00401269 DD 45 A8 fld qword ptr [ebp-58h] 0040126C DD 1C 24 fstp qword ptr [esp] 0040126F FF 15 E8 D4 47 00 call dword ptr [_pApuUpdateHWclock (47D4E8h)] 00401275 83 C4 08 add esp,8 __asm nop 00401278 90 nop _pApuFubar(x); 00401279 83 EC 08 sub esp,8 0040127C DD 45 E0 fld qword ptr [ebp-20h] . . . --------------------------------------------------------------------------------------- So, obviously, inserting a nop into the instruction stream has "corrected" the stack cleanup issue ...

    - 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?

    - 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.

    - 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: create firewall interface "INetFwMgr interface" using CoCreateInstance failed on window server 2003 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).

The .cpp's compile OK but the linker gives unresolved external symbol errors when trying to link my methods. // the abstract class, in abstract.h class CExchange { public: virtual short Exchange(BYTE *pabExchangeBuffer, DWORD eBufferSize, DWORD eNumberOfBytesToSend, DWORD &reNumberOfBytesReceived) = 0; virtual ~CExchange(void) { } }; ///////////////// // My derived class definition in Exchange.h #include "abstract.h" class C_Exchange : virtual public CExchange { public: virtual short Exchange(BYTE *pabExchangeBuffer, DWORD eBufferSize, DWORD eNumberOfBytesToSend, DWORD &reNumberOfBytesReceived); }; //////////////////// // The derived class implimentation in Exchange.cpp #include "abstract.h" class C_Exchange : virtual public CExchange { public: virtual short Exchange(BYTE *pabExchangeBuffer, DWORD eBufferSize, DWORD eNumberOfBytesToSend, DWORD &reNumberOfBytesReceived) { short ret = 0; return ret; } }; /////////////// // And the final use in main() #include "exchange.h" int APIENTRY WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nCmdShow) { C_Exchange* ex = new C_Exchange(); return 0; } It all works until I try to instantiate an object of C_Exchange, at which the linker says: error LNK2001: unresolved external symbol "public: virtual short __thiscall C_Exchange::Exchange(unsigned char *,unsigned long,unsigned long,unsigned long &)" (?Exchange@C_Exchange@@UAEFPAEKKAAK@Z) Also, if I change the include from abstract.h to exchange.h in the cpp the compiler says I have duplicate class definition. I always define a class in a header and implement it in a cpp without problems, why would this one be any different?

    - 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?

    - IMAPI Recording I'm just going through some code I found on MSDN regarding using the IMAPI interface. Unfortunately all it seems to do is enumerate the drives and then display their information, one comment made me laugh // This requires dealing with IEnumSTATPROPSTG--Ugh! That's really encouraging isn't it? Ideally I wanted to do this through VB.NET but examples seem to be a little lacklustre and unfortunately I cannot resort to the VB Accellerator binary that is available. Any pointers in the direction toward something that's a little more intuitive than "Ugh!" I would be most appreciative. Nick.

    - 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: create firewall interface "INetFwMgr interface" using CoCreateInstance failed on window server 2003 Tag: 282296

    - deriving from abstract class I have a class module (class A) where the constructor requires a pointer to an object of an abstract class (class B). I understand that I have to derive another class (class C) from the abstract one and override all the virtual methods in order to instantiate an object. But when I use the derived class C object as the argument for the constructor of class A, the compiler says it can't convert form class C to class B. What to do? Thanks.

    - Recieveing Bulk of Messages of small size using Sockets Hi, I have a client server MFC Socket based application. I am hooking the mouse and sending the event messages to the client. On client im simply displaying the events (real intension is to inject the events using sendInput()). The problem is that on client if i write the messages on file I can see all the messages in order there. but if I try to print (or inject using sendInput()) them I dont get all the messages. also if I write them in file and print them, then again I dont get all the messages in file. One more intrusting thing is that when I use telnet instead it displays all the messages. I have tried using win32 APIs using SOCKET as well instead of using CSocket. but the result is the same. I need to recieve messages without missing any of them. Kindly suggest me what to do.

    - Setting\Getting printer\plotter options I am trying to customize the Print GUI by adding a print previewer. I want to be able to accurately show how the image will come out on the paper, but I am unable to always get the correct information. I can query the devmode and get the Orientation, but that is not always accurate. I have found some printers/plotters do not rotate with Landscape, but require a third choice, "Rotated Landscape". I can set this via their driver GUI but it doesn't seem to change the Devmode in anyway. I am also having the same problem with "Autorotate". Even on machines where Landscape works as expected, if they have Autorotate turned on my previewer may be completely wrong.
