    - can the member function be compared? for example, there is a class as below struct Foo { void Func1() {} void Func2() {} }; As known, &Foo::Func1 != &Foo::Func2 is right, but &Foo::Func1 < &Foo::Func2 is illegal. So std::map< void ( Foo::* )() > can not be defined. Are there some other ways to get the greater and less relationship between two member functions? Thanks! Tag: Debug Control Panel App? Tag: 282807

    - VC++ 6.0 workaround for partial specialization Hello everyone, I am working on a project on Visual C++ 6.0 and I need to port some code that uses partial specialization of class templates: #include <cstddef> #include <iostream> // Extracts the type of an object. template <class T> struct extract { typedef T type; }; // Extracts the type of an array. template <class T, std::size_t N> struct extract<T[N]> { typedef T type; }; // Primary template for object new. template <class T> struct TrackNewHelper { static T* TrackNew( T* ptr, const char* file, int line) { std::cout << "Tracking object allocation" << std::endl; return ptr; } }; // Partial specialization for array new. template <class T, std::size_t N> struct TrackNewHelper<T[N]> { static T* TrackNew( T* ptr, const char* file, int line) { std::cout << "Tracking array allocation " << std::endl; return ptr; } }; // Forwards the call to helper classes. template <class T> typename extract<T>::type* TrackNew( typename extract<T>::type* ptr, const char* file, int line ) { return TrackNewHelper<T>::TrackNew( ptr, file, line ); } #define NEW( T ) TrackNew<T>( new T, __FILE__, __LINE__ ) int main() { int * p = NEW( int ); // Calls the primary template. delete p; p = NEW( int[64] ); // Calls the partial specialization. delete [] p; return 0; } I found a hint on the internet saying that class member templates can simulate partial specialization, but unfortunately, no further information was given. Does anyone happen to know a workaround for the code above? -- Matthias Hofmann Anvil-Soft, CEO http://www.anvil-soft.com - The Creators of Toilet Tycoon http://www.anvil-soft.de - Die Macher des Klomanagers Tag: Debug Control Panel App?

    - Find the MAC address of NIC when the network connection is disabled. Hi all, I need to programmatically find the MAC id of the NIC when the network connection is disabled. The scenario is like this. You have multiple NICs on your PC. Now you go the network connection applet and disable one of the connection. Now if you issue getmac command from command prompt, the mac ID of the disabled connection will not be listed. I want to get this ID programmatically. I tried some WMI methods and GetAdaptersAddresses function to no avail. Is this task possible? Thanks in advance, Shaji. Tag: Debug Control Panel App? Tag: 282797

    - How can LoadLibrary fail? I have a project which attempts to load a DLL with HINSTANCE hInstance = LoadLibrary( pszPath ); where pszPath is the full path name of the DLL. Just occasionally it fails and returns NULL. It has done it for others, but just this week it happened to me for the first time, and so i was able to check one or two things. The path is correct and the DLL is there. The path name is not longer than _MAX_PATH characters. The library in question is a resource-only DLL which has one C++ function in a .cpp file which reads in its entirety: #include "stdafx.h" BOOL APIENTRY DllMain( HANDLE hModule, DWORD ul_reason_for_call, LPVOID lpReserved ) { return TRUE; } How can it fail? [In my case rebuilding the resource-only DLL made it work again, but this does not necessarily work for others with the problem, and so I need to understand what can go wrong!] A bit more detail: Immediately prior to attempting to load the DLL I do a loop using FindFirstFile() FindNextFile() [and I don't forget FileClose()] to store a collection of names of resource DLLs which are present (all of the above content), and have names of a certain form. Then I try to open each one of them, and extract a string from it with a given ID, which tells me more about it. But sometimes, just occasionally, one or more fails to open. [The calling DLL is linked dynamically with MFC and using AfxLoadLibrary() makes absolutely no difference.] Any ideas?

    - Self deleting class Hi, Imagine: CSomeClass* c = NULL; c = new CSomeClass(); delete c; c = new CSomeClass(); delete c; So I must call delete c; to clean up memory. However, instead of doing it like so.. isn't it equally valid to make class self deleting? So, if I do this: class CSomeClass { CSomeClass(); virtual ~CSomeClass() { delete this; } } can I then simply do this? CSomeClass* c = NULL; c = new CSomeClass(); c = new CSomeClass(); What happens when I reassign the valiable to new instance? Will CSomeClass self-delete itself at that point, or when application terminates? Lisa Tag: Debug Control Panel App? Tag: 282765

    - Call unmanaged DLL (VS7.0) from VS6.0 Hello newsgroup, I have to make a confession first: Yes, I'm still using VC6.0 (don't bother telling me that I should download the 'free' 200* Express Edition, as I want to use MFC). Is it possible to call code from an unmanaged Dll written in VS 200[2|3|5] from VS 6.0 code? AFAIK, MS only changed the way how debug information are stored inside static libraries, but this shouldn't affect Dlls. To re-phrase the question: Has the binary layout of classes/structs changed from VS6.0 to VS 200*? Thanks in advance, Stuart Tag: Debug Control Panel App? Tag: 282734

    - Why does this cause "data abort" ? Hi imagine construction like below: class CSomeWnd { public: int m_hWnd; virtual LRESULT SomeWndProc(HWND hWnd, MSG msg, WPARAM wParam, LPARAM lParam); } CSomeWnd* g_pSomeWnd = new CSomeWnd(); g_pSomeWnd->CreateWindow( ... ); ... LRESULT GlobalWndProc(HWND hWnd, MSG msg, WPARAM wParam, LPARAM lParam) { return g_pSomeWnd->SomeWndProc(hWnd,msg,lParam,wParam); } Since I can not register window class with a non-static windows procedure, I can not use a non-static member functions. So above the global static GlobalWndProc 'relays' the message to non-static SomeWndProc, so that SomeWndProc can access member variables easily. However, the above construction causes data abort exceptions. I don't understand why, but it's resolved by something like this: CSomeWnd* g_pSomeWnd = new CSomeWnd(); g_pSomeWnd->CreateWindow( ... ); SetWindowLong(g_pSomeWnd->GetSafeHwnd(), GWL_USERDATA, (LONG) this); LRESULT GlobalWndProc(HWND hWnd, MSG msg, WPARAM wParam, LPARAM lParam) { CSomeWnd* pWnd = (CSomeWnd*) GetWindowLong(hWnd, GWL_USERDATA); return pWnd->SomeWndProc(hWnd,msg,lParam,wParam); } Can someone explain why this is? And.. is there a better way to implement the above? some pattern? Thanks, Lisa Tag: Debug Control Panel App? Tag: 282724

    - Volume Shadow Copy - BackupComplete and VSS_E_BAD_STATE Hello! I'm using and testing VSS both on Xp and 2003. I use CreateVSSBackupComponents(); InitializeForBackup(); SetBackupState(); GatherWriterMetadata(); StartSnapshotSet(); AddToSnapshotSet(); PrepareForBackup(); DoSnapshotSet(); GetSnapshotProperties(); VssFreeSnapshotProperties(); BackupComplete(); Every function works well on 2003. On XP all funcions work OK but BackupComplete returns always VSS_E_BAD_STATE even when the files are succesfully copied. (using every posible installed writer). This has been tested on different XP machines and differents Service packs / patchs to exclude some bad VSS installation or something.... Anybody experimenting the same problem?

    - Making this non-recursive This is a multi-part message in MIME format. --------------090505060907010303040009 Content-Type: text/plain; charset=ISO-8859-1; format=flowed Content-Transfer-Encoding: 7bit Folks, I am in short urgent timeline to get this completed and I desperately need a good student of C/C++ computer science to assist me here. I recently found a stack overflow situation and need to correctly make the following recursive code - non-recursive, specifically the FindTreeRecord() function. I attached findtree.cpp with the C/C++ source code. I wanted to attach an example data file to work with, but it was too large for this post so I made it available at: http://beta.winserver.com/public/test/marshall.zip The main() code has an example deep record to find in the qx file. This HashTable code was designed back in 1996 by a former computer science engineer no longer with us and I guess today with larger users, with deeper nodes in the hash tree, the recursive nature of it is now revealing the stack overflow problem. The FindTreeRecord() is only used to clear specific nodes in the tree. In the zip, this cut down version simply prints out the found node. But in reality, it would clear the node and update the data file. IOW, the true goal of the function is to "Clear" the node during an update process. Some testing details: The example record search shown in the main() code, should provide 4 hits, in an unknown order: [filename] [SYSTEM] [ADDED] [FILE] If you explore this, you will see that I am passing the recursive level so it is printed with each find. You will see it will go pretty deep when a stack overflow occurs. If you put a limit like so in the FindTreeRecord() function; if (tr.Left && level<100) FindTreeRecord(h, tr.Left, qxr, level+1); if (tr.Right && level<100) FindTreeRecord(h, tr.Right, qxr, level+1); You will see that it might find some nodes but not all without the stack problem. The only issue I have is when traversing the tree recursively to find all nodes with a specfic TQXRef value. I would greatly appreciate assistance in making this function non-recursive. Thanks in Advance PS: I am going to switch to a SQL database system, but I need this fixed now until the new SQL version is available. -- HLS --------------090505060907010303040009 Content-Type: text/plain; name="findtree.cpp" Content-Transfer-Encoding: 7bit Content-Disposition: inline; filename="findtree.cpp" // // File: findtree.cpp // compile: cl findtree.cpp /W3 /GX /MD /D "_AFXDLL" // #include <stdio.h> #include <afx.h> #include <conio.h> //--------------------------- // Hash Table //--------------------------- const DWORD QXINDEX_MAXKEYLEN = 64; const DWORD QXINDEX_HASHLIMIT = 4096; const DWORD QXINDEX_LISTBLOCKSIZE = 16; union TQXRef { unsigned __int64 qword; struct { DWORD ref; DWORD area; } dword; }; struct TListRecord { DWORD Next; TQXRef Ref; }; struct TListBlock { DWORD Next; TQXRef Refs[QXINDEX_LISTBLOCKSIZE]; }; #pragma pack(1) struct TTreeRecord { DWORD Left; DWORD Right; TListRecord List; BYTE KeyLen; char Key[QXINDEX_MAXKEYLEN]; }; #pragma pack() const char *qxfn = "marshall.qx"; DWORD HashTable[QXINDEX_HASHLIMIT] = {0}; //--------------------------- // Function Prototypes //--------------------------- DWORD ReadAt(HANDLE &h, DWORD ofs, void *data, DWORD n); DWORD WriteAt(HANDLE &h, DWORD ofs, const void *data, DWORD n); BOOL FindTreeRecord(HANDLE &h, DWORD ofs, const TQXRef &qxr, int level); BOOL FindRecord(HANDLE &h, const TQXRef &qxr); BOOL FindRecord(HANDLE &h, const DWORD area, const DWORD ref); HANDLE OpenQX(const char *fn); BOOL CloseQX(HANDLE &h); //--------------------------- // Main //--------------------------- void main(char argc, char *argv[]) { HANDLE hqx = OpenQX(qxfn); if (hqx != INVALID_HANDLE_VALUE) { try { FindRecord(hqx,569, 1195264); FindRecord(hqx,3, 10496); } catch( ... ) { printf("!!

    - 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! TWP Tag: Debug Control Panel App?

    - 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? Regards Mark Tag: Debug Control Panel App? Tag: 282631

    - 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?

A = A.Increment(); for (j = 0; j < A.GetLength(); ++j) printf(" Entry %d is %d.\n",j,A.GetInteger(j)); return 0; } IntegerArray IntegerArray::Increment() const { IntegerArray dummy(itsLength); for (int j = 0; j < itsLength; ++j) dummy.SetInteger(j,itsInteger[j]+1); return dummy; } IntegerArray::IntegerArray() : itsInteger(0), itsLength(0) { } IntegerArray::IntegerArray(int length) : itsLength(length) { // entries uninitialised itsInteger = (itsLength > 0) ? intvec(itsLength) : 0; } IntegerArray::IntegerArray(const IntegerArray & rhs) : itsLength(rhs.GetLength()) { // copy constructor itsInteger = (itsLength > 0) ? intvec(itsLength) : 0; for (int j = 0; j < itsLength; ++j) itsInteger[j] = rhs.GetInteger(j); } IntegerArray IntegerArray::operator=(const IntegerArray & rhs) { // assignment (deep copy) if (this == &rhs) return *this; if (itsInteger != 0) { // release memory del_intvec(itsInteger,itsLength); itsInteger = 0; } itsLength = rhs.GetLength(); // allocate memory itsInteger = (itsLength > 0) ? intvec(itsLength) : 0; for (int j = 0; j < itsLength; ++j) itsInteger[j] = rhs.GetInteger(j); return *this; } IntegerArray::~IntegerArray() { if (itsInteger != 0) del_intvec(itsInteger,itsLength); } int IntegerArray::GetLength() const { return itsLength; } int IntegerArray::GetInteger(int j) const { if (j < 0 || j >= itsLength) { printf(" Index out of range : IntegerArray::GetInteger.\n"); exit(1); } return itsInteger[j]; } void IntegerArray::SetInteger(int j,int entry) { if (j < 0 || j >= itsLength) { printf(" Index out of range : IntegerArray::SetInteger.\n"); exit(1); } itsInteger[j] = entry; } int * IntegerArray::intvec(int length) { return (new int[length]); // array of integers } void IntegerArray::del_intvec(int * q,int length) { delete [] q; // delete array of integers } Tag: Debug Control Panel App?

    - 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. Tag: Debug Control Panel App?

    - 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: Debug Control Panel App? 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: Debug Control Panel App?

    - 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: Debug Control Panel App?

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?
