    - operator() I am trying to implement a callback mechanism based on gotw #83: http://gotw.ca/gotw/083.htm --------------------- class CallbackBase { public: virtual void operator()(const TCHAR*) const { }; virtual ~CallbackBase() = 0; }; template<typename T> class Callback : public CallbackBase { public: typedef void (T::*F)(const TCHAR*); Callback( T& t, F f ) : t_(&t), f_(f) { } void operator()(const TCHAR*) const { (t_->*f_)(const TCHAR*); } private: T* t_; F f_; }; ------------------------- I've been staring at it for a while now and I can't figure out why the line: void operator()(const TCHAR*) const { (t_->*f_)(const TCHAR*); } gives the following errors: error C2143: syntax error : missing ')' before 'const' error C2198: 'const Callback<T>::F' : too few actual parameters error C2059: syntax error : ')' Tag: how can I get pid & vid Tag: 225049

    - Winsock recv() trouble Ok, I keep getting the error code 10057. I know this is the Socket is not connected error, but I check to see if there is a socket problem all the way up to this point. at the recv() point there seems to be a SOCKET_ERROR. Can anyone help me get this going? If you would like I can post the source code of the server (which is where the problem seems to lie). well, this is part of the code: if( recv( project_socket, command, sizeof(command)+1, 0 ) == SOCKET_ERROR) { cout << "receive error. " << WSAGetLastError() << endl; }; Tag: how can I get pid & vid Tag: 225046

    - dll eat my functions :< Hi! I think it maybe a question difficult to answer. But I hope there are some people share the same experience with me will give me some hint. I find one dll project very weird. There are some functions in the dll to be export. They are declare with extern "C" _declspec(dllexport). But some function(about 5%) can't be find in the generated dll. (I used ultraedit to search for the name in the dll binary) I finally find out it have some relation to its parameter. for example int funcNoUse(long lRegionID) { return 0; } will be ok, it's generated in the dll. But if i change it to int funcNoUse(long lRegionID, long nPoints, float* pY, LPCTSTR szFlags, int makeCopy) { return 0; } it will not exist in the dll. I really don't know what's up. I have test it on two computer one with VS7 and another with VS7.1 have the same result. any idea? Tag: how can I get pid & vid Tag: 225044

    - Doug Harrison, please! Thanks to everyone who answered my questions about SEH, specifically "volatile" one! (Please see thread: SEH and standard C++ exceptions) I have some more questions, which is regarding Doug Harrison's post: // Assuming everyone observes the locking protocol, this approach // would work on all hardware, even weird architectures like Sparc // and others which require memory barriers: bool x = true; // As above, just non-volatile for (;;) { lock(mx); bool y = x; unlock(mx); if (!y) break; whatever; } This is new and interesting to me. Is this solution better than using "volatile bool x = true;"? "2. You need volatile to avoid undefined behavior in certain signal handler and setjmp/longjmp scenarios." Would you mind to give us some examples about this? "3. You can use volatile, say, to declare a pointer to a volatile int, which represents a memory location updated at the interrupt level, something you can't synchronize with, and which is outside the compiler's knowledge of the program." This is totally beyond my apprehension. Would you please elaborate more on this point? Tag: how can I get pid & vid Tag: 225032

    - Newbie: Allocate 2 dimentional-array Hi, With these code: int a[3][5]; we are allocated (static) an array 3-by-5 (but continous) elements. But how to allocated dynamically an 3x5 array ? The way i know is: a = new int *[3]; a[0] = new int[5]; a[1] = new int[5]; a[2] = new int[5]; Too complex for a simple task ! and the allocated space is not continous ! Anyone know the way to allocated dynamic an array with continous space in C++ ? (in pascal, it's quite easy to do such thing ). Thanks in advance ! Tag: how can I get pid & vid Tag: 225013

    - Unresolved external symbol I have defined _WIN32_WINNT 0x0500 and subsequently included windows.h. My g:\dotnet\vc7\platformsdk\lib is among the lib search directories and contains kernel32.lib which exports CreateWaitableTimer() and SetWaitableTimer(). And though it shouldn't be necessary, I have explicitly specified kernel32.lib among additional dependencies. My code compiles but won't link: unresolved external symbol _CreateWaitableTimer unresolved external symbol _SetWaitableTimer What could be the problem? I even notice in the linker's verbose output that kernel32.lib **is** searched, and, for example, SystemTimeToFileTime() is found. Oddly, I have another project which uses those two unresolved functions and it has no problem linking. Thanks. -- - Vince Tag: how can I get pid & vid Tag: 225006

    - vector::resize bug Hi I think im dealing with a possible bug using vector objects. Specificaly a vector of CComPtr(s) related objects that contain even sinks. Lets say i got a ATL class that handles events from a COM object using IDispEventImpl<,,,> ---------------------------------------------------------------------------- ------ class CSomeClass : public IDispEventImpl<,,,> { public: CSomeClass (){} ~CSomeClass (){} CComPtr<ISomeComObject> m_pSome; BOOL Create() { m_pSome.CoCreateInstance(,,,); return TRUE; } BEGIN_SINK_MAP(CSomeClass ) SINK_ENTRY_EX(0, DIID__ISomeComObjectEvents , 0x01, OnLoad) END_SINK_MAP() VOID __stdcall OnLoad(){} }; ---------------------------------------------------------------------------- ------ then if do this : vector<CSomeClass> m_vSome; m_vSome.resize(2); m_vSome[0].Create(); m_vSome[0].DispEventAdvise(m_vSome[0].m_pSome); m_vSome[1].Create(); m_vSome[1].DispEventAdvise(m_vSome[1].m_pSome); m_vSome.clear(); No problem, everything is fine and dandy! BUT if i do this >> ( 2 resize operations) vector<CSomeClass> m_vSome; m_vSome.resize(1); m_vSome[0].Create(); m_vSome[0].DispEventAdvise(m_vSome[0].m_pSome); m_vSome.resize(2); m_vSome[1].Create(); m_vSome[1].DispEventAdvise(m_vSome[1].m_pSome); m_vSome.clear(); CRASH BANG! , , the event connections are lost during the "second" resize operation. So i had to do this to get things to Work : ... for(i=0; i<m_vSome.size(); i++) HRESULT hr = m_vSome[i].DispEventUnadvise(m_vSome[i].m_pSome); UINT size = m_vSome.size(); m_vSome.resize(size+1); m_vSome[size].Create(); for(i=0; i<m_vSome.size(); i++) HRESULT hr = m_vSome[i].DispEventAdvise(m_vSome[i].m_pSome); ... And now everything works.. Anybody ever had this issue before ? Tag: how can I get pid & vid Tag: 224984

    - Debugging OK - picture the scenario. I want to develop a program using C++. I don't have any Visual Studio IDE (please don't say "but I thought you did" - this is for a different environment) I am of the belief I can build unmanaged C++ applciations using all of the things available in the downloadable .NET SDK v1.1, which is free, and downloadable from MS in a huge 108 MB package Now - I have thus got all I need to compile my C++ source code. I am perfectly happy to type my source code into notepad. This is in fact what I WANT to do. Then I thought, this is all fine. But if I want to debug, what options do I have? I asked a question about where the standard downloadable debuggers were but all I got was a link to some kernel/DDK based page - I'm not into kernel or device driver development, just standard windows apps - but using the downloadable (free) SDK - what method do people normally employ to debug applications of this type - do they a) get the application to create a console window to output messages? Or b) use a standard debugger I haven't seen yet? c) use a third party tool d) Or do they have to pay for the IDE if they want to debug Tag: how can I get pid & vid Tag: 224931

    - Select multi files and folders Hello, I need to get an option to select multi files and folders in the same time, I can select files by using CFileDialog class and folders by using SHBrowseForFolder. Is there a way to enable both in the same time, the perfect thing will be like in the windows explorer where you can select what ever you want. Arnon Tag: how can I get pid & vid Tag: 224830

    - CWebBrowser2 issue I am trying to set the location of a web browser control, and, then, immediately afterward, I want to throw some text into one of the form fields on it. The problem is that the system doesn't seem to immediately update the page the browser is in. For instance, I might do: mycwebbrowser.Navigate("c:\test.html", NULL, NULL, NULL, NULL); and then if I try to get a form field, it will come back NULL. Any ideas how to make the navigation complete?

If you're developing for Windows NT/2000/XP only, you can have a look at
WMI, e.g. it's hardware classes at
