    - How can I communicate with a service? Hi, I'd like to design a software that is mainly made of a service and that would need a user interface to view and edit the configuration. Now, what I need to know is: Is it possible for an independant exe to connect to a service and get data from it or send data to it? If it's possible, what is the best way to do it?

    - Memory Problem Hi all I'm having a problem with the memory management: I'm writing a program with Visual C++ which creates, after a call method, a lot of structures and classes and afterwards they are deleted completely; but I open the Windows Task Manager and the memory used by my program is is always increasing, is it correct or memory should decrease after deleting the classes and structures with 'delete'?? Any idea?? Of course, the problem is that when I'm inserting (but not storing) quite data, my program reaches 200 MB and I think that there is something wrong!

    - GetWindowDC twice Hi Is it ok to call GetWindowDC twice on the same window before ReleaseDC ? HDC dc1 = GetWindow(hWin1); HDC dc2 = GetWindow(hWin1); ... ReleaseDC(hWin1, dc2); ReleaseDC(hWin1, dc1); I usualy only do it once but I noticed that sometimes my drawings calls generate a WM_PAINT message and then id get BeginPaint EndPaint which pretty much does get/release of dcs. thanks a lot.

    - template specialization bug Hello, I think I have found a template specialization bug in Microsoft Visual C++ 2003 (VC7.1). The following code compiles with gcc3.2 and Intel 8.0, but gives error C2764 "template parameter not used in partial specialization" with VC7.1. The workaround would be to repeat the complex type deduction done in DefinesAType for the specialization of SomeClass, which is code duplication and error-prone. //a class that has public typedef template < typename T > struct DefinesAType { //assembles in a complicated (assumed) //way a new type from T typedef T AType; }; //class SomeClass will be specialized template < class T> class SomeClass {}; //specialize on the type defined in DefinesAType template < class T > class SomeClass<typename DefinesAType<T>::AType> { }; int main() { SomeClass<int> sc; } Tag: About copying files Tag: 226221

    - <char*> data with process-to-process messages Hi there, I register a custom message with RegisterWindowMessage function. I would like to pass <char*> messages via the message: char buf[80]; .... // fill the buf with a message SendMessage( HWND_BROADCAST, MYMESSAGE, (WPARAM)buf, NULL ); this of course does not work as expected: the array is correctly received only in the process that sends the message. all other processes cannot see the message data (I suppose this is due to memory beeing virtually adressed in each process). my question is: how then should I declare the memory to be able to pass the data to another process as <char*>? I've tried to alloc the memory globally (via GlobalAlloc) and pass the pointer but with no result. The only solution I've found is to register the data as an atom (GlobalAddAtom) as pass the atom handle. This solution, however, does not look like a general one. thanks in advance for your help, Wiktor Zychla Tag: About copying files Tag: 226206

    - Dll exporting a function that creates MFC dialog is causing crash in MT. Hi I am facing a crash only in 2k with the following scenario . In XP and 98 this problem is not observed In my scenario I have X.exe, Y.dll. Y.dll exports a function (say Z) which has DoModal() of a dialog called. X.exe on click of a button starts a thread and in that thread calls the Z method which shows up a dialog. The problem happens when the button is clicked thrice or more than thrice. The three dialogs are lauched in three threads and are shown. But if I try to move the dialogs, After some time a crash is seen, whcih occurs in a method of MFC42.dll. More information about the scenario is X.exe links Y.dll statically. X links MFC as a shared dll, where as Y.dll links the same as a static dll. I suspected module state change when the the control is going out of thread boundary to Dll. But the exported function already has AFX_MANAGE_STATE(AfxGetStaticModuleState( )); as te first statement. Please let me know if any body faced the same problem before and point me towards the solution. Thanks Sre Tag: About copying files Tag: 226202

    - try block performance I have two pieces of code performing virtually the same task. While one of them (f1) is written in a try block, hoping to catch as many exceptions as possible, the other one (f2) is not: void f1 (void) { try { do_task1(); do_task2(); do_task3(); } catch (exception1){...} catch (exception2){...} ... } void f2 (void) { do_task1(); do_task2(); do_task3(); } Does f1 imposes any necessary runtime-overhead? Is to answer this question implementation dependent? And if so, is there a general answer applies to most implementations? ben Tag: About copying files Tag: 226200

    - AfxBeginThread I have an ATL / MFC project which creates an ATL-based dialog box. When the dialog is created I want to spawn a worker thread. The code to create the thread is: DWORD dw; CWinThread* pThread = AfxBeginThread(SendFileFTP, (LPVOID) &dw); The thread proc is defined as this: UINT CUploadProgress::SendFileFTP(LPVOID pParam) { CProgressCtrl* pBar = (CProgressCtrl*) GetDlgItem(IDC_PROGRESS1); for(int x = 0; x <= 10; x++) { pBar->SetPos(x); } return 0; } But when I try to compile, it get this error message: error C2665: 'AfxBeginThread' : none of the 2 overloads can convert parameter 1 from type 'unsigned int (void *)' I suppose it's all very obvious, but could someone help me with this?

    - Threads Hi, I want to create a thread and this thread should wait some messages and behave accordingly... Lets say I derived a class from CWinThread.. I think the execution point is determined by the function that will be passed as an argument to the AfxBeginThread function.. UINT MyThreadFunc(LPVOID lParam) CMyThread *myThread = (CMyThread *) AfxBeginThread(MyThreadFunc,NULL, THREAD_PRIORITY_NORMAL,0,0); Now I want to post some messages to myThread by PostThreadMessage.. I have already defined message handlers for some user messages #define WM_USER_THREAD_UPDATE_PROGRESS (WM_USER+0x102) ON_MESSAGE(WM_USER_THREAD_UPDATE_PROGRESS, OnThreadUpdateProgress) it seems I will handle this messages into MyThreadFunc with GetMessage and PeekMessage and after TranslateMessage and DispatchMessage OR this messages will come to the PreTranslateMessage of CMyThread..(?) if I will handle messages in MyThreadFunc then the function will look like this.. UINT MyThreadFunc(LPVOID lParam) { while (GetMessage(...)) { //if message is destroy thread, then quit.. //else TranslateMessage(...) DispatchMessage(...) } } the syntax may not be correct.. but whose message pump GetMessage function gets messages? I mean if I had two thread with the same function, what will happen? I hope I can explain what i thought:) if preTranslateMessage gets the messages, the there will not need for MyThreadFunc, so it should wait until the thread is terminated???! Please tell me I am wrong or not.. Thanks anyway.. Tag: About copying files Tag: 226166

    - UNICODE vs _UNICODE First off, how come there is both a _UNICODE and UNICODE symbol used in the Win32 API? Second off, what is the distinction, if any? I've noticed that for builds to work w/o errors, I need to either have both defined or neither. So, anyone feeling descriptive? I'd really like to know which I should officially be using in code where I need to detect whether building with or w/o it (i.e. #ifdef UNICODE vs #ifdef _UNICODE).

    - Inline methods Hi all, I have always defined inline methods for a class in a header file (either the header in which the method was declared, or in a separate one for the sake of more readable library headers). So I would end up with something like: ////// some_class.h ////// class SomeClass { void someInlineMethod() { // Do stuff } void someNormalMethod(); }; ////// some_class.cpp ////// #include "some_class.h" void SomeClass::someNormalMethod() { // Do more stuff } A while back, I came across some C++ code specifically for MSVC that actually defined methods in the .cpp file as inline, like so: ////// some_class.h ////// class SomeClass { void someInlineMethod(); void someNormalMethod(); }; ////// some_class.cpp ////// #include "some_class.h" inline void SomeClass::someInlineMethod() { // Do stuff } void SomeClass::someNormalMethod() { // Do more stuff } When I try to do this in MSVC.Net, I sometimes get a linking error saying something to the effect that the linker cannot find the method that I declared as inline (sorry, I don't have the exact error message in front of me). Other times, it works fine, although I don't know for sure that the method is actually being inlined. Can anyone shed some light as to the true way to define inline methods, preferrably in a platform-independent sort of way? Dave Tag: About copying files Tag: 226158

    - Create() Not sure if this is the place for this question but it is as good a place as any. I have a multi-threaded application (up to 65 worker threads). I was wondering how to debug my problem. when I do the following from the masterthread(called from timer interrupt) everything works ok, however if I try it in my worker thread(trying to speed up the code execution) I get an Access Violation exception thrown. Code: CMyClient m_client; //Create an instance here if (!m_client.Create()) This is where I get the error. { ... } else { ... } the CMyClient.h file contains class CMyClient : public CSocke {...

    - Version Number Format Okay, I know that Microsoft, as a standard, uses the following format for version numbers (dotted quad notation): Major.Minor.Build.Revision (example 1.15.0015.0) Also, I know that often this version information is stored in a binary form in a double word, such as a REG_DWORD in the system registry. So, I have a helper class that reads either DWORDs or string representations of a version number and then provides checked access to either one of the four fields, Major, Minor, Build, or Revision, and finally allows you to read the whole version number as a string or DWORD. This is so that I can easily read in version info as a DWORD or string from the registry or a file and then do comparisons. To finalize everything, I'd like to make sure that I'm packing/unpacking my four fields into and out of the DWORD correctly. Does anyone know Microsoft's format? I know Build needs least 12 bits (from some version numbers I've seen) but I'm not sure on others. Any help appreciated.

    - Regarding SerializeElements and byte swapping Hi, This is regarding SerializeElements. SerializeElements does a bit-wise read or write of the elements if (ar.IsStoring()) ar.Write((void*)pElements, nCount * sizeof(TYPE)); else ar.Read((void*)pElements, nCount * sizeof(TYPE)); Does this(bit-wise read/write) eliminate endian issues. I mean if I store ints in a container, serialize it and send it across the n/w(to a big endian env); would there be endian issues; would I have to do byte swapping? I heard that the stream operators >> and << do byte swapping internally. Kindly help. Thanks and Regards, M Shetty Tag: About copying files Tag: 226126

    - multithreaded - Thread / Threads - hang / freeze - on AfxBeginThread I have made a thread previously over this issue, but wanted to bring attention to it again and start fresh so that I donâ??t make any assumptions I have an application that communicates to the user through RF devices (telnet). Constraints placed upon the application required it to be written in two pieces 1) One piece is a VB application that communicates with the RF devices through winsock controls. This application acts as a gateway between the RF devices and the actual application where most of the process occurs 2) The other piece is a multithreaded MFC VC++ application without an interface that runs as a process. This is where most processing occurs. For each RF device connected and needing to run, a new thread is created that communicates to the RF device through the VB app via the shared named pipe The main communications loop in the VC++ application is WatchPipe. Watch pipe creates new threads when needed and communicates with existing threads accordingly All that to get to the problem The problem is eventually and by all appearances as a random act, when WatchPipe creates a new thread it sometimes hangs and never returns The function to launch the new thread is bool LaunchProcess(CThreadState * ThreadState char *ProcedureName = "TL_RF.LaunchProcess" bool Launched = true CLogIt Logit( ProcedureName, ThreadState ) // I never actually use ThreadState->WinThread (should I ? ThreadState->WinThread = AfxBeginThread( ThreadedFunctionLauncher, ThreadState, THREAD_PRIORITY_NORMAL, 0, CREATE_SUSPENDED, NULL ) ThreadState->WinThread->m_bAutoDelete = false ThreadState->WinThread->ResumeThread() return( Launched ) The first parameter in AfxBeginThread i (AFX_THREADPROC pfnThreadProc) Points to the controlling function for the worker thread That function (chopped down) looks like thi UINT ThreadedFunctionLauncher( LPVOID pThreadState CThreadState * ThreadState ThreadState = (CThreadState *)pThreadState char *ProcedureName = "TL_RF.ThreadedFunctionLauncher" CLogIt Logit( ProcedureName, ThreadState ) ThreadState->SendResponseToTLRF( "Entering thread" ) tr /* Do stuff here * catch( _com_error &e HandleCOMError( ProcedureName, e, ThreadState ) } catch( exception * e SendErrorToDevice( ThreadState, ProcedureName, e ) catch( CException * e SendErrorToDevice( ThreadState, ProcedureName, e ) ThreadState->SendResponseToTLRF( "Exiting thread" ) EndAction(ThreadState) Logit.Log( "Exiting" ) return( 0 ) The program seems to hang on the AfxBeginThread call in LaunchProcess The way I see the hang is through the log files that are being generated by the CLogIt Logit( ProcedureName, ThreadState ) Line in each function The ClogIt class logs an â??enteringâ?? line on itâ??s constructor, and an â??exitingâ?? line on its destructor When the program hangs we have logged that we have entered into the routine, but there is no entry in the log to support this routine ever returned An example log for a successful previous call looks like this 02/09/2004 12:06:24 - 127.0.0.1 TL_RF.LaunchProcess Enterin 02/09/2004 12:06:24 - 127.0.0.1 TL_RF.LaunchProcess Exitin 02/09/2004 12:06:24 - 127.0.0.1 TL_RF.ThreadedFunctionLauncher Enterin The last entry in our logs after the application has hung show 02/09/2004 12:13:37 - 10.20.155.1 TL_RF.LaunchProcess Enterin with no additional entries I can verify that the application is still running, and I can verify that the main thread for communication is in fact hung Also, this is running on a dual processor machine hosting terminal services.

    - Disk Management API HELP! A few days ago, I got a help on APIs to do the Device Manager job. Now I am a bit in trouble. Without using a Windows GUI, I need to do the followings. Can SetupDiXXXX allows me to do it? # Reactivate "Disk 1" shown in the Disk Management after enabling Disk 1 using SetupDiXXXX. Just as a note, my application is a kind of an "embedded system" and there is not GUI to the user. Thus I have to manipulate the contents of the Disk Manager just with Windows APIs, meaning that without opening those control windows. I will be looking forward to hearing from anyone for the help! Thank you in advance. Mark T. Tag: About copying files Tag: 226083

    - "enum" in a class: Is it statically available? Hi! Probably a stupid question, but: Do I need to declare an "enum" static for it to always be available from a class? Like this: class Canvas { public: static enum STATE <--- Is static necessary here, or is an enum considered a constant? { STATE_ALPHABLENDING, STATE_AUTOINVALIDATE, STATE_CREATED }; ... I probably could have tested it, but I just don't care to create a special program for such testing when there is guaranteed to be someone out there who already know...

Respected Sir,

How to copy one database file from one location to
another through code in VC? In the same way how to copy
one wav file from one location to another through code in
VC?

How about...

CopyFile( szSource, szDestination, TRUE );
