The first declaration is saying that if the * operator is used on a CYObject then return a reference to an xObject. The second declaration is saying that if the -> operator is used on a CYObject then to return a pointer to an xObject. Let's assume xObject has a public int called nValue. For the first operator (*) you can use xObject & myxObject = *myCYObject; int myValue1 = myxObject.nValue; and for the second operator (->) it's int myValue2 = myCYObject->nValue; > English is not my first, or second, language > so anything strange, or insulting, is due to > the translation. > Please correct me so I may improve my English!

 - Can someone explain how these operator is suppose to work Hello, I'm using a 3:rd party library and in one class I have a protected variable that I need to get. I see that the creator of the class has two operators that seem to be the trick to get the value but I don't get how to use the operators. The class looks like this Class CYObject { protected: xObject* m_pObject; // a number of other variables... public: xObject& operator*(){ return *m_pObject;} xObject* operator->(){ return m_pObject;} } If I have an instance of CYObject called myObject how do I get the myObject->m_pObject?? // Anders -- English is not my first, or second, language so anything strange, or insulting, is due to the translation.

 - How to save data to Access database file! Hi All, Good afternoon, I am working on winamp general purpose pluggin "gen_whatsplaying " project downloaded from the site www.schaffrath.net I compiled and build the project successfully using platform SDK Feb 2003 and Speech SDK5.1. Now the winamp plugins "gen_whatsplaying" interface saving the data related to songs currently being played by Winamp to a specified text file. such as time the song starts playing, name of the song currently being played etc. depending on the parameters specified in the pluggin's template file. Now, I want to save the data directly to a MSAccess database file, which is currently being saved in a text file, such as time the song starts playing, name of the song currently being played etc.depending on the parameters specified in the pluggin's template file. e.g. "6:23:39 PM- D:\shaan\03 WOH PEHLI BAAR.mp3" this information I want to store in two different field of Access database table. please let me know how do I do that? Do I need to use ADO and other library to get the connectivity with MSAccess db first? Let me know if you have any idea about it. I really appreciate yours help and kind cooperation with me.

But in this case i don't have privilege to load this dll only if certain criteria is met. I don't want to change the already written code to explicit linking.

 - C++ quirks - frustrated with secure CRT [long] Hi everyone, I've been researching and asking this question around quite a lot today without a satisfactory answer. I have difficulties interpreting the documentation for the secure version of some CRT methods and I would like to know some opinions if you would care to share. As a rule, it seems that most of them take an extra parameter of type size_t which is usually called sizeofbuffer which - despite the name hint that a C\C++ programmer would take it as indication that the byte size is what needed to be passed - actually requires the number of elements in the array to be passed and , considering wide char versions as well as TCHAR versions the documentation insists that one passes _countof instead of _sizeof where that parameter is required: TCHAR buffer[512]; _secure_method_s(buf, _countof(buffer),...);//good!! _secure_method_s(buf, _sizeof(buffer),...);//bad!! as exemplified by _tcscpy_s sample from MSDN: errno_t _tcscpy_s( TCHAR *strDestination, size_t numberOfElements, const TCHAR *strSource ); strDestination Location of destination string buffer numberOfElements Size of the destination string buffer.//jabba : oh well let's not be explicit here strSource Null-terminated source string buffer. MS sample: char string[80]; // of course we can supply the size explicitly if we want to: strcpy_s( string, _countof(string), " strcpy _s!" ); //note usage of _countof But witness definition of _vsntprintf_s int _vsntprintf_s( TCHAR *buffer, size_t sizeOfBuffer, size_t count, const TCHAR*format, va_list argptr ); Parameters buffer Storage location for output. sizeOfBuffer The size of the buffer for output./*note jabba : size expressed as WHAT?????Can't you give me more info than what is already comprised in the name of the parameter????*/ count Maximum number of characters to write (not including the terminating null), or _TRUNCATE. format Format specification. argptr Pointer to list of arguments. It would seem (by hints of the naming used for parameters, not through explicit parameter documentation )that sizeOfBuffer refers to the actual size in bytes of the buffer so a good call would be int nSize = 0; TCHAR buff[10]; memset(buff, 0, sizeof(buff)); va_list args; va_start(args, formatstring); nSize = vsntprintf_s( buff, sizeof(buff), _TRUNCATE, formatstring, args); MS being the nice guys that they are only provide a regular char sample: int nSize = 0; char buff[10]; memset(buff, 0, sizeof(buff)); va_list args; va_start(args, formatstring); nSize = vsnprintf_s( buff, sizeof(buff), _TRUNCATE, formatstring, args);//hello what am I supposed to infer??? That is byte size of course!!! Ha! But look what the vswprint.c (CRT source code) definition looks like: int __cdecl _vsnwprintf_s ( wchar_t *string, size_t sizeInWords,<-----exactly the opposite hint! size_t count, const wchar_t *format, va_list ap ) So it looks like they expect you to pass the count of elements in the array instead of its byte size. I can produce this kind of open to interpretation MSDN documentation for a lot of other secure CRT methods. Anyone has any experience with this that can confirm whether all of the secure methods require consistently the buffer's byte size or all of them require the element count or does it really vary from method to method and what's the definitive hint on which one to pass?

 - LINK : fatal error LNK1104: cannot open file "nafxcwd.lib" Hi all, I'm a C newbie in a desperate need of help. My background isn't programming but engineering, so my programming skills are somewhat limited (I am able to write simple single-threaded progs in C, but hardly more than that). It just happened that my work requires me to take a program and strip it off all kind of GUI, make it just a simple command prompt thingie. And so I did, more or the less. Now, I didn't remove any includes or anything of a kind, but my stripped proggie consistently refuses to link (compiling is OK) and the error I get ts the one in the subject. I searched all of my hard drive, this file doesn't exist on it. But the original program never "jumped" on it, as if it never required it in a first place. As I said I never added anything to the program, only removed some of the GUI related code... And the new program seems to require something that the old one never did... I'm open to any suggestions, as due to my limited programming skills I just don;t know where to look for the problem's root. Thanks! Tag: vc++ 2005 express support making dll? Tag: 277186

 - local type as template argument Hello all, I wonder whether anyone has seen a workaround for this somewhere, perhaps in Boost or elsewhere... I succeeded using a local type as template argument in MSVC 8.0, but I found out that this violates the standard (14.3.1.2), and sadly does not work with g++. I was essentialy able to run some code for each local type before main() - see the source code below. Thanks for suggestions, Filip #include <iostream> #include <list> using namespace std; // common interface struct XC { virtual const char* get_data() = 0; virtual ~XC() {} }; typedef list<XC*> XCL; XCL global_list; template<typename Y> struct X : public XC { X() { // make this instance globally accessible... // this runs before main() for each X // instantiation global_list.push_back(this); } virtual const char* get_data() { return get_data_static(); } static X initializer; // return data associated with Y static const char* get_data_static() { return data; } // data associated with Y static const char* data; }; template<typename Y> const char* X<Y>::data=Y::getYData(); template<typename Y> X<Y> X<Y>::initializer; int main(int argc,char* argv[]) { // the local type whose data // will be visible globally struct Y { static const char* getYData() { return "some data"; // make sure X<Y>::initializer exists X<Y>::initializer; } }; // walk the list of X specializations: XCL::iterator i, e=global_list.end(); for(i=global_list.begin(); i!=e; ++i) cout << (*i)->get_data() << endl; // use X<Y> directly: cout << X<Y>::get_data_static() << endl; return 0; } Tag: vc++ 2005 express support making dll?

VC++ 2005 Platform SDK 2003 R2 - Windows Core Platform SDK 2003 R2 - DirectShow Platform SDK 2003 R2 - Web Workshop DirectX SDK (April 2007) However, when I tried to compile and link, the following errors occur VMR_Capture.obj : error LNK2020: unresolved token (0A0000FA) CLSID_VideoInputDeviceCategory VMR_Capture.obj : error LNK2020: unresolved token (0A0000FB) CLSID_SystemDeviceEnum VMR_Capture.obj : error LNK2020: unresolved token (0A0000FC) IID_ICreateDevEnum VMR_Capture.obj : error LNK2001: unresolved external symbol _CLSID_VideoInputDeviceCategory VMR_Capture.obj : error LNK2001: unresolved external symbol _IID_ICreateDevEnum VMR_Capture.obj : error LNK2001: unresolved external symbol _CLSID_SystemDeviceEnum Do anyone knows what the problem is? These symbols are part of Uuids.h and its been included in dshow.h Thanks in advance Tag: vc++ 2005 express support making dll? Tag: 277066

 - #ifdef inside macro expansion Hello, I have the following code: ======== void function( const char * ) ; #define CALLF( string ) function( string ) int main() { CALLF( #if 1 "string" #endif ); } ======== Microsoft compilers are unable to compile the code. The compilers I tested are the following: - Orcas Beta1, version 15.00.20404 for 80x86 - VS2005 SP1, version 14.00.50727.762 for 80x86 - XDK April2007, version 14.00.5603 for PowerPC (The newest version of GCC as well as Comeau C++ compile the code and it works as intended, i.e. passes "string" to f.) The error message given is the following: ==== vm.cpp(9) : error C2121: '#' : invalid character : possibly the result of a macro expansion vm.cpp(9) : error C2143: syntax error : missing ')' before 'if' vm.cpp(9) : error C2660: 'function' : function does not take 0 arguments vm.cpp(9) : error C2121: '#' : invalid character : possibly the result of a macro expansion vm.cpp(9) : error C2059: syntax error : ')' ==== The reason is that preprocessor does not remove the #if directive, so the preprocessed output looks like this: ==== void function( const char * ) ; int main() { function( #if 1 "string" #endif ); } ==== I tried to check the C++ and C99 standards to see whether or not this is a bug in the compiler, but I haven't really found the answer. I'd like to ask the people who know the standards and who read this forum whether compilers should work with this code or whether the behavior is undefined in the case of preprocessor directives inside macro expansion. The workaround is simple (not using preprocessor directives inside macro expansion), so I'm only asking on ideas whether or not this is a bug in the compiler that I should report via the MS connect site.

 - p/invoke, __clrcall, Run-Time Check Failure #0 My code uses several pointers to unmanaged functions via dllimport. For some reason, though I didn't change the calling convention, when I declare the pointers, the compiler insists on viewing the dllimported functions as __clrcall (See thread: http://groups.google.com/group/microsoft.public.vc.language/browse_thread/thread/e371441aa1d9603d/a7aec9c7412141a9?lnk=gst&q=__clrcall&rnum=2#a7aec9c7412141a9) I think this is coming back to bite me in a later function call, now. Down along the line -- when calling one of my pointers -- the app freezes when debugging. If I run it without the debugger, I get the following error: "Run-Time Check Failure #0 - The value of ESP was not properly saved across a function call. This is usually a result of calling a function declared with one calling convention with a function pointer declared with a different calling convention." Running a p/invoked function as __clrcall doesn't make much sense, so that must be the problem. But I didn't choose to do it that way. Even when I explicitly declare the imported functions as __cdecl, when I assign the pointer, VC++ tells me that: error C2440: 'initializing' : cannot convert from 'void (__clrcall *) (mupdf::Data::fz_colorspace *,float *,float *)' to 'void (__cdecl *) (mupdf::Data::fz_colorspace *,float *,float *)' None of the functions with this name in scope match the target type Using a static_cast gives the exact same error.

 - Question about compiler bug: Value-initialization in new-expression I recently got into trouble because MSVC++ appeared to incorrectly implement value-initialization, for a struct that I was using. Luckily the bug was reported in 2005 already, by Pavel: Feedback ID 100744, "Value-initialization in new-expression". https://connect.microsoft.com/VisualStudio/feedback/ViewFeedback.aspx?FeedbackID=100744 The example has a struct that looks very much like mine: struct A { std::string s; int i; }; When doing "new A()", the int data member does not get zero-initialized, as it should. Jonathan Caves (Visual C++ Compiler Team) has admitted that it is indeed a bug. Note that other attempts to value-initialize the struct fail as well: #include <cassert> class B { A m_a; public: B(): m_a() { assert(m_a.i == 0); // Assertion fails! } }; int main() { A a1 = A(); assert(a1.i == 0); // Assertion fails! A a2((A())); assert(a2.i == 0); // Assertion fails! B b; return a1.i + a2.i; } This is a serious bug! Is it going to be solved with the next service packs of VC++ 2003 and VC++ 2005? According to the Feedback page, the status of #100744 is "Closed (Won't Fix)". Does that really mean that this bug won't get fixed at all???

 - Undefine storage specifier Hi, I was compiling same 3 party software. The DirectX 9.0 SDK file: "<DirectXRoot>\include\dsound.h" uses the type definition "DWORD_PTR". dsound.h does not define or include a header file that define DWORD_PTR. Other typedefs like GUID and DWORD are define. Is there a header file that defines miscellaneous Windows C++ types? Should I add the line: #define DWORD_PTR long* to the dsound.h header file?

 - retrieving asynchronous ('immediate') mouse position? hi everybody, i'm building a virtual world (engine), and i use the mouse and WSAD keys to manouver through it. i've tried WndProc(), GetCursorPos, and MOUSEMOVEPOINT to read the mouse position. but they all result in cluttering when i use mouse and keys at once. i've asked something like this in an earlier stadium, but i thought i'd solved it by switching to GetCursorPos. i need an immediate/asynchronous mousePos, independent of the event que, and keyboard activity. anyone? i looked it up in msdn 8, but i couldn't find an easy fix. regards, marco RTYpe 6 Tag: vc++ 2005 express support making dll?

I have another custom class for making the column headers multiline. It gets control by this method and does work, but it tried taking the same approach for the SortCtrl and it doesnt work. HeaderCtrl Method for getting control: CHeaderCtrl* pHeader = NULL; pHeader=m_cList2Ctrl.GetHeaderCtrl(); m_HeaderCtrl.SubClassWindow(pHeader->m_hWnd); I tried using this below method to get control of CListCtrl, but it would'nt work: CListCtrl& ctlList = GetListCtrl(); Anyone help would be greatly appreciated.

When I call DCOM on remote machine from a test asp page, it calls the DCOM successfully, but when I call that DCOM from my application, then it doesnot makes the call to remote machine. The only thing different between both Application Pool is that, DefaultAppPool works on NETWORK SERVICE and my application pool works on LOCAL SYSTEM. Anyone having the idea, what is the problem? When I change it from Local System to Network Service, then DCOM call generates properly but my application stops working. -- Regards, Muhammad Nasir Waqar Tag: vc++ 2005 express support making dll?

hey all,
recently, i download free vc++ express edition, it works well, and
what's more it's free to use.
but i find that this version seems does not support making dll file? i
like to create a project which will simply output functions in a dll
file, but the radio button for dll is disabled in "application type"
of application wizard.
is that still possible to create a dll project with vc++ express
edition?
p.s. i try to find anwser with google, but the most related page is
in japanese language, which looks like a puzzle to me :(

thanks a lot.
regards,
