    - some headers seems to conflict the others Hi everybody, I have a sort of strange problem, I need to search for a special file (perl.exe) in run time and searching the help I have found out CFileFind but it needs afx.h to be included. The problem is when I include afx.h some other parts of my program which were being built and working properly seem impossible to be built. an example is Directory::GetCurrentDirectory(). I had a similar problem with including windows.h. again some formerly proper statements seemed to turned out to unproper ones after including windows.h and Directory::GetCurrentDirectory() was one of them. The error message in both cases are the same and seem even stranger to me. It is :" error C2039: 'GetCurrentDirectoryA' : is not a member of 'System::IO::Directory' " I don't have any GetCurrentDirectoryA. what the problem could be?

    - Visual C++ 6.0 Hello all, We have a client that needs an update to an old Visual C++ 6.0 application. One of our developers has tried to get it working in VS.NET 2005 but he says he's having troubles with the DLLs and linking. We have a current MSDN Professional subscription, but we do not see Visual C++ 6 on there, only 4.x and below. Is there any way we can get the 6.0 version?

    - rs232... Hello Scott and everyone else who will read this post. After many messages that I posted on the news groups about rs232, I have come up with functional code which reads in as many as 25 characters in one operation, meaning that a micro-controller can send 25 bytes to the PC and VC++ has no problem reading this. The code can be altered to read many more bytes than 25 if required, however I only tested up to 25. All you need to do is to change the first defined statement > BYTESTOREAD! Scott, I have learnt a lot form our exchage of posts, so I figure I would like to share with you, what I have come up with, and I would appreciate your opinion â?¦ However, I know that the code can probably be made more efficient, however I think, for me, for now, its quite okay! This is not the way I will leave the code, there will be some final touches such as better placement of #define statements and so forth! I will put comments under every line of code, so if you disagree with the commentary feel free to correct it. ////////////////////////////////////////////////////////////////////// #include <windows.h> CSerialWnd MySerial; //Create an object of Cserial type. LRESULT CALLBACK WndProc_CW1 (HWND hwnd, UINT message, WPARAM wParam, LPARAM lParam) { //RS232 *Receive mode #define BYTESTOREAD 25 //Depicts the amount of bytes to read! #define OB_BYTES ((BYTESTOREAD*2)+1) //Number of bytes for official Buffer ! static DWORD dwBytesRead; //Declaration of variable to indicate actual bytes that are //read in within the time limit that windows allowed! static byte CatchByte_BUFFER[BYTESTOREAD+1]; //Bytes returned from the MySerial.Read() function, will be //immediatelly assigned to this array. static byte Accum_BUFFER[BYTESTOREAD+1]; //Since windows cannot assure a constant amount of bytes //returned from the MySerial.Read() function(which come // from the rs232 port), then when CatchByteBUFFER //is full, I transfer its bytes to the Accum_BUFFER. So //now, CatchByteBUFFER is ready for another, set of bytes //returned from the next MySerial.Read() function. static TCHAR Official_BUFFER[OB_BYTES]; //This array holds the final and complete string that was read in . int k,n,j; //General purpose variables used to loop and index arrays //RS232 SERIAL PORT MONITOR if (message == CSerialWnd::mg_nDefaultComMsg) { const CSerialWnd::EEvent eEvent = SerialWnd::EEvent(LOWORD(wParam)); const CSerialWnd::EError eError = CSerialWnd::EError(HIWORD(wParam)); switch (eEvent) { case CSerialWnd::EEventRecv: // A serial message occurred j = 0; //Holds Accumulative array index value do { MySerial.Read(CatchByte_BUFFER, sizeof(CatchByte_BUFFER), &dwBytesRead); //Read the port, and the third parameter //will hold the amount of bytes read in!

After spending many hours on the subject, I thought I could shine some light on rs232 in a laymens kind of way, I know for many of you, this is probably unworthy of your time or knowledge, however, if I would of have had this type of post 3 months ago, it really would of made the rs232 implementation curve a lot simpler for me! I invite anyone that is a beginer and finds rs232 complicated just as I did, (and still do! Because I am sure there is much more to this) to use it and improve upon it! I have one question though! What is the advantage of using the Wndserial class as opposed to using functions like CreateFile, WriteFile, ReadFile, and CloseHandle. Would I be better off, or is it because in Windows it would be too complicated! Just asking! I thank Scott and all members of the news groups that have helped me on the subject! You guys, are a great resource on the subjects of C,C++,VC++. -- Best regards Robert Tag: want to see trace of programe execution on text file . Tag: 269260

    - cin and binary mode Is there any chance of slightest light at the end of the tunnel in pursuing the cin and binary mode operation together? I am trying to see if I can open the cin in binary mode for read operation. I am using VC++ with VS .NET 2003 While using VS 6.0, it was a piece of cake, but since there were a lot of things just removed in VC++ .NET 2003 version, I am having a hard time converting this little piece of code.... previously with VS 6.0 it was, istream_withassign myFile; filebuf *myFileBuf; ....... myFileBuf = new filebuf (_fileno(stdin)); myFileBuf->setmode(filebuf::binary); myFile = myFileBuf; // stream object is stream buffer if (!(myFile.read(data, nBytes))) { if (myFile.eof()) { status = M_EndOfFile; } else ..... } Which worked just fine. Any ideas or hopes of converting it to VC++ .net 2003? I have done something like this.... which obviously does not work..... It reads the EOF before I expect it to. And it may be something with the cin not opened in binary mode. std::istream* myFile; .......... myFile = &std::cin; if (!(myFile->read (reinterpret_cast<char*>(data), nBytes))) { if (myFile->eof()) { status = M_EndOfFile; } else .......... } Any help is appreciated.....

    - rs232? Again.... Hello, I have had success doing rs232 where my cpu can read from my PC. I am now trying to get my PC to read from my cpu. I had success on this also, 2 months ago at reading 8 bytes into the PC end. Everything was fine, however, today I had the uncontrollable urge to try to read 9 bytes!!!!!! Well guess what? back to the drawing board I am! :-) I want to ask a very simple question and go step by step! Because I though I understood what I was doing 2 months ago after extensive research on the subject, but I am obviously wrong! On my cpu end, I am sending a string like this: /////////////////////////////////////////////////////////////// char RS232_1_ExtOut[] = "ABCDEFGH"; for(i=0;i<7;i++) fputc(RS232_1_ExtOut[i],COM_1); ///////////////////////////////////////////////////////////// As you can guess, this sends a string of eight characters out on com 1 of the cpu! Now, on the PC side (VC++) I have: /////////////////////////////////////////////////////////////////// static DWORD dwBytesRead = 8; static BYTE abBuffer[9]; int TEMP; MySerial.Read(abBuffer,sizeof(abBuffer),&dwBytesRead); TEMP++; ////////////////////////////////////////////////////////////////// Okay, I have a break point on the "TEMP++;" line! For starters, ain't I supposed to read 8 bytes max, hence the variable dwBytesRead? And, abBuffer has enough room to hold the total amount of bytes read plus a null termination character. Right! So why, at this particular moment at breakpoint time! , abBuffer contains, "ABCDEFGÃ?Ã?" 2 Months ago when I got this to work, in the cpu code, I used to send a null character "\0" after my string. I stopped doing this, because I realized it didin't have any effect. I have been told before by news groups fellows that rs232 returns many bytes, but isn't the purpose of the: MySerial.Read(abBuffer,sizeof(abBuffer),&dwBytesRead); function, supposed to limit the amount of bytes read to the value passed in the 3rd parameter? All suggestions and help is very appreciated! P.S. Does anyone know where I can get documentation describing all of the Serial class.... I tried to ask this to the author, but got no response!!! -- Best regards Robert Tag: want to see trace of programe execution on text file . Tag: 269220

    - read from an istream object Hi, This is what I am trying to do - If the filename is given I have to read from the file else I have to read from cin. The program below compiles fine but while reading from cin, it reads some part of the stream fine but encounters an EOF prematuerly. If I read from the cin in a file I see the full data. So I know that cin does get all the data, just that the read function behaves in an unexpected way. std::istream* myFile; // stream object to read the cin std::filebuf* myFileBuf; // specifies a streamBuffer ....... if (!myFileName) { myFile = &std::cin; } else { myFileBuf = new std::filebuf; if (!(myFileBuf->open (myFileName, std::ios::in | std::ios::binary))) { status = My_FileOpenErr; } else { myFile = new std::istream (myFileBuf); } } ......... Then I have the read function if (!(myFile->read (reinterpret_cast<char*>(mydata), nBytes))) { if (myFile->eof()) { status = My_EndOfFile; } else { status = My_IOErr; } } Please help, Thanks in advance.

    - Application design for shared data repository programmed in VC on Win32 Hello folks, This might be slightly offtopic but not very much so ,since the development is to be done in VC for Win32 environment. I have a requirement whereby there is an in-memory data repository which should be housed in a certain binary module . The access to this in-memory data repository is only through an API exposed by the same binary module.The operations allowable are the creation of new record , deletion of record , update of record, and record search. Moreoever this binary module should provide this API to any application on the same machine and simultaneous access ( protected by some synchronization primitive for data integrity ofcourse ) is also allowable. Now i have a couple of ideas on how to implement this on Win32 ,but would also like to hear about any advice or suggestions that you might have. One of the ideas i am thinking of is along these lines. The binary in which the data repository is housed ,should be a DLL , with exported functions that provide the API for data access. Any application which wants to use the data repository ,would load the DLL in its address space. There should be exactly one copy of the data ( let us say for the sake of discussion for the time being , in a statically allocated array of structures ) for as many applications that have loaded the DLL. The data structure would be a global in the dll. -The memory is typically owned by the any process that loads the dll , so how do we make it sure that this data structure has memory which is common to as many processes that have loaded the DLL. How does this type of design sound , i would really appreciate any comments and suggestions on this. Or any related best practices. thanks in advance. regards Taha Tag: want to see trace of programe execution on text file . Tag: 269205

    - VC++ 6 vs. VC++ express: please advise I'm planning to write some code for a friend (for free), and may use C++, which I haven't used in 5 years. Just installed my VC++6 on Windows xp home edition. Since my recollection of MS VC++ has faded anyway, I was thinking of trying their free VC++ express (I love C++ but never gave MS VC++6 high marks for user friendliness). I have some questions and reservations, and would appreciate any advice. --Will installing the free VC++ express mess up my installation of VC++6, somehow making that less usable? I imagine installing VC express might answer the remaining questions, but I'm a bit afraid to do that without reassurance about its effect on VC++6. --does VC express have the full ISO C++, including STL? --are there restrictions, like amount of memory used, size of arrays, etc? --does it produce reasonably fast code? --is it easy to get started? --what else does VC express lack that the full commercial product has? --any other comments are welcome My code is not going to be polished professional work--just a favor for one friend. But I do need STL, operator overloading, reasonable speed of execution, and to be able to read/write text files on disk and display info to the user. Basically, the program is going to read *a lot* of data, do some *lengthy* numerical number crunching, write some results back to disk, and display some results. Thank you all!

    - What the L? in wsprintf Hi, I'm programming in Visual C++ 2005 Express Edition and am having a problem with wsprintf. I'm trying to display a variable value on screen, here is my code: wsprintf(pelement->string, L"%d", (UINT32)val); Only the most significant character shows up. L"%2d" or L"%3d" doesn't really help. If I use just "%3d" without the L it just displays %3d on the screen. Text works fine with the line: wsprintf(pelement->string, L"%s", "test"); Others I have talked to don't even use the L, so why do I seem to need it. Why does it not display integers correctly?

    - Strange delete memory failure Hello all, I have the following problem: i am declaring something like that: char* mystring = new char[200]; then i'm filling the string. After lloking the memory, it looks like it is correct with 4 no man's land bytes before and after the string and correct length. However, when deleting (delete [] mystring), it causes a debug assertion failure even if just before the delete, my string is still well defined in memory. How can such a thing happen? I know I am doing a lot of processing between declaration and delete and that could be that i am writing at the wrong adress but this is not the case here. What should I check in this case? thanks for any help. bye F. Tag: want to see trace of programe execution on text file . Tag: 269178

    - COMDAT folding - which flags disable it inadvertently? Howdy; I'm wondering which compiler flags in VC++ 2003 and 2005 would inadvertently disable COMDAT folding? Reading one of Raymond Chen's blog posts, /Za definitely kills COMDAT folding support. The reason I ask is because we're replacing some old non-templated arrays with templated array types in one of our larger projects, and we're getting a huge increase in size via a Release build with the relevant COMDAT-specific flags turned on. Also: can COMDAT folding occur cross-library? Or is that only possible if Whole Program Optimization and Global Optimizations are turned on? Thanks!

    - Profiling code with optimisation on Hi, I have some templated vector code to unroll a loop, see below. I am trying to test this code against a simple a*a + b*b + c*c vector dot product to see if it truly is producing the same code. I ran the code below and had a look at the assembly listing and it does look like the inlining works, but unfortunatly the optimising power of the compiler is so great that it substituted my code for a simple: int main() { printf("%f", 14.0f); return 0; } which is great, but not what i want for profiling purposes :-). I still want some optimisation for inlining the code, just not so much. NOTE: I only have the basic optimise for speed settings, nothing fancy like global intrinsic functions.... template<typename _Value> struct Vector { _Value _value; }; template<typename _Vector> struct VectorDotProd {}; template<typename _Type, int _Length> struct VectorDotProd<Vector<_Type[_Length]> > { typedef Vector<_Type[_Length]> _Vector; __inline static float Apply(_Vector const & vector0, _Vector const & vector1) { return Impl<_Type, _Length-1>::Apply(vector0, vector1); } template<typename _Type, int _Index> struct Impl { __inline static float Apply(_Vector const & vector0, _Vector const & vector1) { return vector0._value[_Index] * vector1._value[_Index] + Impl<_Type, _Index-1>::Apply(vector0, vector1); } }; template<typename _Type> struct Impl<_Type, 0> { __inline static float Apply(_Vector const & vector0, _Vector const & vector1) { return vector0._value[0] * vector1._value[0]; } }; }; int main() { typedef Vector<float[3]> Vector3f; Vector3f v0 = {1.0f, 2.0f, 3.0f}; Vector3f v1 = {1.0f, 2.0f, 3.0f}; float result = VectorDotProd<Vector3f>::Apply(v0, v1); _RPTF1(_CRT_WARN, "v0.v1 = %f\n", result); printf("%f\n", result); return 0; } Tag: want to see trace of programe execution on text file .

Hello, I implemented a simple tooltip for my deskband which is only shown sometimes. for example after activating the deskband and hover over the band, the tootip is shown. it is not shown, when the time of the tooltip is eleapsed (smoothed out) and i hover the cursor again over the band. it is also not shown when i click on the desktop and then hover the cursor over the band. ..sounds difficult?! :-) to understand what i mean, have a look at the tooltips of the tray icons. they are shown always. has anyone an idea what's happening here? i looked at the msdn lib, used google, but all without success. thanks for any tips and advices! ////////////////////////////////////////////////////////////////////// m_hWndToolInfo = CreateWindowEx( WS_EX_TOOLWINDOW, TOOLTIPS_CLASS, NULL, WS_POPUP | TTS_NOPREFIX, CW_USEDEFAULT, CW_USEDEFAULT, CW_USEDEFAULT, CW_USEDEFAULT, m_hWnd, // Window Handle of Deskband NULL, g_hInst, // Instance of Deskband NULL); if (m_hWndToolInfo) { SetWindowPos(m_hWndToolInfo, HWND_TOPMOST, 0, 0, 0, 0, SWP_NOMOVE | SWP_NOSIZE | SWP_NOACTIVATE | SWP_SHOWWINDOW); char strTT[400] = "Some Text"; LPTSTR lptstr = strTT; // Initialize Members of the Toolinfo Structure m_ti.cbSize = sizeof(TOOLINFO); m_ti.uFlags = TTF_SUBCLASS | TTF_IDISHWND; m_ti.hwnd = m_hWnd; m_ti.hinst = g_hInst; m_ti.uId = (UINT)m_hWnd; m_ti.lpszText = strTT; // Send an TTM_ADDTOOL to the Tooltip Control SendMessage(m_hWndToolInfo, TTM_ADDTOOL, 0, (LPARAM) (LPTOOLINFO) &m_ti); SendMessage(m_hWndToolInfo, TTM_ACTIVATE, true, 0); } ////////////////////////////////////////////////////////////////////// Tag: want to see trace of programe execution on text file .

    - ref / value structs I`m having some trouble calling functions from a c++\cli dll from my C# code. I pass in structs (that are defined in the DLL) as ref types. When I try this I get an error. When I create them as value types the function works fine with the same syntax on the C# side. Can you also point me to some artical on the subject, since I can`t find anything...

    - why the service manager doesn't start my service Hi, all, I have a question, and I hope to get some hints here.. I created a really simple service just to check why the service manager doesn't start my service the second time if the first time failed.. I created an atl service through the wizard, and the only thing I do is override the PreMessageLoop()... HRESULT CAutoStartServiceModule::PreMessageLoop(int nShowCmd) { HRESULT hr = CAtlServiceModuleT<CAutoStartServiceModule, IDS_SERVICENAME>::PreMessageLoop(nShowCmd); if(FAILED(hr)) return hr; //return a false here.. //log event here.. LogEvent(_T("Failed to start the service, should retry ....")); return E_ABORT; } And in the service control panel, i set "Recovery options" as First Failure: Restart the service.. Second Failure: Restart the service.. Subsequent Failure: Restart the service.. But the service was not restarted ... I wonder maybe I miss something to report the right information back to the service control manager.. Thanks for any help.. J.W. Tag: want to see trace of programe execution on text file .

    - Alocating memory for vector of structs Our need is to dynamically allocate memory for an stl vector of structs which contain vectors in some of their fields: vector< struct{ int; float; vector<int>; vector<int> } > The size of the int vectors is not constant; it varies from element to element depending on the input. How can I most efficiently allocate the memory needed for this? Thanks! Tag: want to see trace of programe execution on text file . Tag: 269101

    - "Unspecified Error" while cleaning a project Hi all. When I do a right-click on a particular project in a solution and try to "clean" it, or look at the "properties", I get an "Unspecified Error". I understand this must have got something to do with my messing around with the .vcproj's and the .sln's by hand. But I have no clue as to how to go 'bout it. I'm using VC++ .NET 2003. Any help will be greatly appreciated. Thanks in advance. Nishant. Tag: want to see trace of programe execution on text file . Tag: 269086

    - console winevents and codepage change on 2 or multi cpu systems Hey guys, any help would be appreciated. Background: My system basic specs is Windows XP, SP2, VC6. Intel P4 Hyperthreading. This problem occurs only if there is more than 1 cpu(hyperthreading or Dual Xeon). I am using SetWinEventHook to get notification of console winevents. Events 4001h-4007h After I setup the hook, I run several console applications, let's use cmd.exe as an example. all is well, notifications are coming from all the windows and I was happy for a while. Yet... When I run CMD.EXE, and then run "chcp", I get the active codepage. if I try to change it using "chcp 437", the CMD.EXE process hangs. Same happened if I use a console application of my own and use the api SetConsoleOutputCP to change the codepage. If the console process didn't hang for the first time, opening a second console application(or cmd.exe) and changing the codepage causes it to hang. Assume the only line of code in the WINEVENTPROC that fires is int i=0; No global variables, no calls. so the problem is not within the proc. I tried WINEVENT_OUTOFCONTEXT and WINEVENT_INCONTEXT methods with EXE's or DLL's, exact same results. I tried hooking only 4007h event, same results. The problems occurs only in the console events(4001h-4007h), other events work great. If I UnHook the events, change the codepage(works) and hook back, it works but it's just not supposed to be this way! ! ! and it is not good for my design. On single processor systems it works well, on multi processor systems it only works If I set the affinity of CSRSS to only one CPU and so on (not a good solution obviously, just for the sake of testing...) then all is working well. Questions 1. WTF? 2. Am I doing something that is not thread safe ? 3. Is this a bug in windows ??????? is their api not thread safe ? 4. Not related to the problem(I am not using VB for the above problem), does any one know why UnHookWinEvent doesn't work in VB(doesn't unhook) ? while SetWinEventHook is working great.?

    - User Breakpoint Unhandled Exception Error VS.NET 2003 I was browsing the other posts on this topic but I need to enquire further on it. I'm experiencing the same User Breakpoint Unhandled Exception on one of my machines. My main desktop. Possible heap corruption ( if it is in fact a heap corruption, how do you trace the and remove it?). Then I decided to run the project on my laptop with the same version of VS.NET (2003) and it ran without error or interruption of any sort in all modes(release, debug). I'm really not sure what else to try as I need to get it back functioning normally on my desktop which is my main development machine. Especially due to the fact that it has a video card supportive of the advanced graphics technologies that I plan to use in the project. Any assistance on my situation is much appreciated.

    - TreeView and GetCheck() results In a TreeView with checkbox style when I check or uncheck a box the immediate result is always a bad result. Example: I click on a checkbox and in the OnClick() function I go to see if the value is 0 or 1; the value is always wrong and if I clic in the same checkbox on in another one the result is always the previous result. I've tried with UpdateData(true\false) but no changes happen. I can see that SetCheck() work fine but not GetCheck . What's the problem? Tag: want to see trace of programe execution on text file .

    - Unauthorized memory allocation - Possible VC2005 bug? Hi, I have a relatively small Visual C++ project using MFC which allocates unusually hight amount of virtual memory as soon as the program starts(roughly 280MB), even before hitting the internal MFC stuff. When I debug them program in Visual Studio 2005 with a breakpoint at the beginning of int _tmainCRTStartup(void) function in crt0.c Windows Task Manager shows the following information: Memory Usage: 5,620K Peak Memory Usuage: 5,620K Page Faults: 1,420 VM Size: 282,360 K Paged Pool: 632K NP Pool: 2K Handles: 102 Threads: 1 GDI Object: 6 Running the program in release mode produces the same result. Also, compiler/linker settings are almost set to default. My question why the program allocates so much VM, before even its started WinMain() function? Is it a Windows issue or Visual C++?

    - Quick question! Hello, How are you all doing today... I hope only good! :-) I am trying to read a byte from my PC into a micro processor using RS232... I know I know, you all though I had finally got this done... But you see, I never really tested the part where the processor had to read the bytes in from the PC! It appears just as complicated as the vice versa operation which is reading in bytes from the processor by which I have done! And since the available controls on the CPU side are very limited, I must be carefull on what I issue from the PC side! I am using the popular serial class... here is the problem I hope to resolve! I am sure its got something to do with the windows variable types!!! ? Simply put, here is the bulk of the code: ////////////////////////////////////////////////////// LRESULT CALLBACK WndProc_CW1 (HWND hwnd, UINT message, WPARAM wParam, LPARAM lParam) { TCHAR zzz[] = TEXT("5"); char xxx[1]; ...other code... case WM_COMMAND: //Convert Wide characters to byte sized charaters WideCharToMultiByte(CP_ACP,0,zzz,1,xxx,0,NULL,NULL); MySerial.Write(xxx); return 0; ...other code... } //////////////////////////////////////////////////////////////////////// Basically, when I converted the wide character to multi byte, and I put my cursor over xxx, I get: "Ã?Ã?Ã?Ã?Ã?Ã?Ã?Ã?Ã?Ã?5" Shouldn't I just be getting the, "5". The reason I am asking this is that my processor gets two rs232 interupts instead of just one, and reads in "Ã?" on the first interupt and "Ã¿" on the second interupt. I obviously need only the "5"! Overall I thing that I am somehow sending out wrong information, but why? Does someone know why this is happening! I thankyou all for any resolutions to this problem!

    - ? Function Pointer to a Method of Unknown Class Hi, I've got a class which needs to store a pointer to a function. The class will use that as a callback to pass some data to the specified function when the data changes. I need to be able to pass a method of the required format from an unknown class to it. For example: typedef void(*Z)(int); class A { int i; Z fp; void ReadI(); } class B { void init(); void Foo(int t=0;); A m_a; } class C { void init(); void Bar(int x); A blah; } ... void A::ReadI() { i=somechange(); fp(i); } void B::init() { m_a.fp=Foo; } void B::Foo(int t) { cout<<t; } void C::init() { blah.fp=(Z)Bar; } void C::Bar(int x) { int i=x; } Unfortunately, I keep getting an error saying that it cannot convert from the function to the typedef. I took a look around but came up empty. Is this possible? If not, is there another way that works (preferably simple)?

    - DLL exporting with __declspec or .DEF file? I've been reading several posts, MSDN articles and VC Help but it's still not clear to me whether or not an EXE has to be recompiled if an implicitly linked DLL changes. Currently, all of our applications are statically linked and we are considering converting our library code to a DLL. From what I've read, implicit linking seems to be the simpliest to implement but I'm concerned about the statements I've read that says if you are using __declspec to export/import and you change the DLL then you have to recompile the EXE's that implicitly link to the export lib. We are using purely C code, no C++ and the testing that I've done seems to indicate that additional functions can be exported from the DLL and the EXE's run fine without recompiling. Is this just by shear luck? I guess I'm trying to understand if using __declspec exports by name or ordinal and if using __declspec is the way we should go or if we should be using the .DEF method, though this method seems to carry a high maintenance overhead. All of the code is under our control and the DLL is meant to be used only with our applications. We simply think switching our library code over to a DLL will allow us to provide bug fixes to existing code without having to redistribute all the applications that use the library functions and add new library functions needed for new applications.

    - Is there SP6 for Visual C++ 6.0 ? Microsoft's web site says here: http://tinyurl.com/foqqc that "Service Pack 6 for Visual Basic 6.0, Visual C++ 6.0 with Visual Source Safe 6.0d" is "recommended for all users of Visual Basic 6.0, Visual C++ 6.0 and Visual Source Safe 6.0." But the title reads "Visual C++ 6.0 *with* Visual Source Safe 6.0d". I am confused: Is SP6 good for standalone Visual C++ 6.0 or is it good only for the version that comes with Visual Source Safe 6.0? Currently I have SP5 installed on top of my VC++ 6.0 and I would like to know whether SP6 can benefit me in anyway. (please don't advise me to upgrade to Visual C++ 2005, since I am planning to do so anyway. However for an intermediate period of time, I still need to use MSVC 6, just to make sure that I am not breaking a current legacy system) Thanks, Victor Tag: want to see trace of programe execution on text file .

1. Set focus to stack window.
2. Press Ctrl+A (or choose from context menu: "Select All")
3. Press Ctrl+C (or choose from context menu: "Copy")
4. Paste clipboard content to Notepad.
