    - LNK 4210 comes when i migrate from VC6.0 to VC8.0 Hi, I had a DLL build using VC 6.0. I migrated the Source to VC8.0. Now I am getting the linker error "LNK4210: .CRT section exists; there may be unhandled static initializers or terminators". Please note that I have my own DLL Entry point specified in the make file for the DLL. I have checked documentation. I have tried to call _CRT_INIT function in my entry point funtion but then i get the LNK2001 unresolved external symbol CRT_INIT. Can anybody tell me the exact problem and fix for it. As far as I can figure out the constructors for global members is called by run time library. but in this case i am not able to initialize the run time library (_CRT_INIT ??)

    - IE toolbar ,How i can reflect the Settings Hi My IE toolbar is based on the Microsoft sample KKBar. I have draw a lot of buttons on it in which some are simply pushDown buttons and some are dropdowns.Beside this I have Made a Setting button.By which user can Customize the Buttons on toolbar,means S/He can select the buttons and deselect the buttons from a Property page. This information i have placed in Windows registry.When I create the toolbar i Create the toolbar based on the registry data that which button i have to appear and to which Button i have to HIde . I have completely Done it.they appear and disappear properly. But the trouble starts when i Create the toolbar i can decide From the registry data that which button i have to make appear and which button i have to make disappear. If the user Selects the setting and change the options (suppose he want to display one more button from the setting),How i can refresh my toolbar to show that button on the same instance of IE. Plz if some one knows tell me .i will be thankful to him.Buttons are displayed when i start another instance of IE,this is just bcoz the Data in the registry has been changed by the previous instance,But i want also to be on the instance that is changing the options.

    - InterlockedCompareExchange64 under VC++ 6.0: in-line assembly using cmpxchg8b ?? I am trying to implement an atomic compare-and-exchange of a "double" type, under VC++ 6.0 for WinXP. The Windows API function of InterlockedCompareExchange64 is not available for WinXP (it's only available for Vista, see http://msdn.microsoft.com/library/en-us/dllproc/base/interlockedcompareexchange64.asp ) . There is a compiler intrinsic function of _InterlockedCompareExchange64 (see http://msdn2.microsoft.com/en-us/library/ttk2z1ws(VS.80).aspx ), but this intrinsic seems to be available only for more recent versions of VC++ (such as VC++ 2005), and it's not available as an intrinsic for VC++ 6.0. So, I think that I need an in-line assembly function which, like the 2005 compiler intrinsic, uses the cmpxchg8b instruction. In-line assembly, however, is beyond my capability. I found user-mode code that uses in-line assembly and the cmpxchg8b instruction at this thread in microsoft.public.win32.programmer.kernel (see the next-to-last post): http://groups.google.com/group/microsoft.public.win32.programmer.kernel/browse_thread/thread/ecc0a35d9fcef3b5/0e3b6a23d301a62a . The code doesn't work for me. Here's what I mean by "doesn't work": I implemented the function in a singly-threaded environment, simply to test whether the function properly stores the correct double value at the destination location. As expected (since we're in a singly-threaded environment), the function's return value indicates that the current value of the destination agrees with the comparand's value, and that the exchange was successful. However, the value that actually gets stored at the destination address is bizarrely corrupted, and does not agree with the exchange value. Can anyone offer any insights (other than a suggestion to upgrade to VC++ 2005)? Maybe someone knows of the assembly code used by the current compiler's intrinsic? Best, Mike Tag: VC6 SP6 Tag: 265685

    - Send/Post Messages on Vista Hi all, There're two apps, A and B on Vista. Using FindWindow() with caption of a window, it proves that B can find the window of A. However when B calling PostMessage() to shot down A of the window, it doesn't work. My understanding is that both A and B are in the same session since they are running under the same user login. Does this mean that both SendMessage() or PostMessage() will not work anymore even in the same session on Vista? If not, there's a way to implement this, better off without any dialog pop-up for user's interaction? Thanks, DH Tag: VC6 SP6 Tag: 265681

    - rs232! Hello, As I read the following document a few times at: http://www.codeproject.com/system/serial.asp given to me by fellow friend Jochen in my previous post I am ready to give rs232 a crack at it! :) I am using the "Windows messages" option of rs232 interfacing (See document). In spite of me using VC++ for 9 months now, I still consider myself a beginer when it comes to much of the language and especially the VC++ GUI. Here is my first problem. I have started to code for the rs232 as indicated in the above link's web document as so: #define STRICT #include <tchar.h> #include <windows.h> #include "CSerialWnd.h" I still don't know what the "#define STRICT" statement is doing there? But I am just copying the sample. Given the above include statements I get the following error at build time: c:\_DTS_PROGRAMMING\C_PROGRAMMING\vc++\MY_APPS_LAB\RS232Test_XPPLC\WndProc_CW1.cpp(20): fatal error C1083: Cannot open include file: 'CSerialWnd.h': No such file or directory In the document, it clearly states that I need to include the serial class header file, in which I did, and I must make sure that the header-files of this library are in my compiler's include path. Up to now all I am used to is including windows.h and some odd header file that I created. I don't know how to include the header files of CSerialWnd library in my compiler's include path. I didn't get very far, but its a start and I don't know what to do, I tried to look at the project properties to see if there is a field that requires include paths, or something like this.... I would appreciate any guidence or direction towards this! Any help is very appreciated! Thanks -- Best regards Robert Tag: VC6 SP6 Tag: 265672

This code should be working, or I should get a compiler error. I'm not looking for workaround. I just want to understand - am I wrong, or there is something with the compiler.

    - Memory Management Hi everyone, I have implemented a memory manager for some SDK I'm working on (a game engine). The primary goal of this memory manager is to reduce fragmentation, to perform fast allocation of small blocks of memory, and to give more detailed information about memory leaks. This manager works fine, and without problems. Now, as you might have guessed already, my problems are the operators new and delete. I wish to overload them in a *safe* way, such that the memory manager is automatically used. I do not want to use class-based new/delete operators. It also has to work properly with other libraries, including the STL. I did overwrite the global operators, and that woks, but it just doesn't feel safe. I realize that there's a good chance, that you'll tell me, that there's just no good and safe way to do what I want. But maybe I'm wrong, and someone here's got this great idea :-) There's just got to be some way to write a cusom memory manager. Thanks, Niki Tag: VC6 SP6 Tag: 265587

    - LoadLibrary question Hi All, Could anyone please let me know if it is possible to load a library which has been built with a /MD compiler witch into an exe which has been build with a /ML compiler switch using 'LoadLibrary'? I am sure that it can be done, but I want to know what will be the implications of such a load? Would that be a good idea? Also, if at all I am to load a dll into an exe which has been statically linked to C runtime libraries (using /ML option), should the dll to be loaded be also statically linked to C runtime libraries or it will be OK if the dll has been dyanamically linked with C runtime libraries (using say /MD option)? Thanks, Tushar. Tag: VC6 SP6 Tag: 265564

    - MS Developement Environment Toolbar Question I had someone code a piece of software for me so I bought Visual Studio .NET 2003 Pro so I could build the project should I ever have the need. I have all of the source code for the project. I open the project and click build and it goes thru fine. I open the project and the toolbar icons are off...its like the edge of one gets cut off and shifted to the next toolbar icon..When he compiles it this doesnt happen because I have a compiled exe of the ones he did. Is there a setting that is causing this??? If you need more info let me know and I will post up. Tag: VC6 SP6 Tag: 265563

    - question about how threads work I am new to threading and I have the following program, but I am unsure about one thing. This program prints out 5 numbers from 0 to 4 or if I take out the Sleep(1000) in IFK_ThreadedRead, it prints out 0 to 405. What I don't really understand is why if I increase the Sleep(5000) statement in the test_interfaceKit function just after the thread is called, it will print out more numbers. I would have thought that the function the thread calls would print out 0 to 999, end the thread and then wait for 5 seconds. It acts like the thread is constantly being called. I am a bit confused about this and I thought I would ask someone who knows a bit more how threads work. Hopefully, you can clear this up for me. Z.K. ---------------------------------------------------------------------------- int __stdcall IFK_SensorChangeHandler(CPhidgetInterfaceKitHandle IFK, void *userptr, int Index, int Value) { printf("Sensor %d is %d \n", Index, Value); return 0; } DWORD WINAPI IFK_ThreadedRead(LPVOID lpdwParam) { CPhidgetInterfaceKitHandle IFK = (CPhidgetInterfaceKitHandle )lpdwParam; while(1) { for( int i = 0;i < 1000;i++) { printf("num = %d\n",i); Sleep(1000); } } printf("Closing down IFK Read Thread \n"); return 0; } int test_interfacekit() { HANDLE m_ThreadHandle; unsigned long m_sThreadIdentifier; int result = 0; CPhidgetInterfaceKitHandle IFK = 0; CPhidgetInterfaceKit_create(&IFK); result = CPhidget_open(IFK, -1); if (result) { printf ("No InterfaceKit found...\n"); return 0; } CPhidgetInterfaceKit_set_OnSensorChange_Handler(IFK, IFK_SensorChangeHandler, NULL); m_ThreadHandle = CreateThread(NULL, 0, IFK_ThreadedRead,(void *)IFK, 0, &m_sThreadIdentifier); printf ("And we wait for it to shut down from an error, or 10 second timeout\n"); Sleep(5000); CPhidget_close(IFK); CPhidget_delete((CPhidgetHandle )IFK); return 0; } int main(int argc, char* argv[]) { test_interfacekit(); return 0; } Tag: VC6 SP6 Tag: 265560

    - Project dependencies I have a VS 2005 C++ solution that has 3 projects. One builds a DLL, the next a static version of the same library, and finally a test program that uses the DLL. The build order shows the DLL first, then the static, then the test program (which is the startup project). If I do a rebuild solution (which is successful) and then do F5 to run, it always tells me that the DLL is out of date and rebuilds it before running. What things do I look for to find out why this is happening? Thanks! Tag: VC6 SP6 Tag: 265542

Hi all, I am trying to run an MFC app; it compiles OK, but when I try to execute it, I get a message box saying "This application has failed to start because lib2d.dll was not found". This is mystifying because on tools->options->directories->include files, it shows that the dll (and corresponding lib file) directories are specified! Whats up? TIA Paul Tag: VC6 SP6 Tag: 265541

    - problems with __gc* (newbie) Hi everyone, sorry for this trivial problem...but I think I'm missing some information to solve it .-) I'm trying to call a method that is specified in the following way: public object get_Item(ref object Index) I've tried to call it using a pointer, containing an integer value : System::Int32 * myInt; myRes->get_Item(myInt); but the compiler gives me the following message: "cannot convert parameter 1 from 'int __gc *' to 'System::Object __gc *__gc * '" .... what is a object of class System::Object__gc*__gc*??? I suppose I must give as input parameter a number (it's an index), ...but how expressing a number with the previous object? I understand that behind my doubts there is "a lot" of lack in VC programming...can someone give some hints about what I should learn first? Many many thanks and excuse me for the question, but I'm just beginning to try to understand VS environment !!! Bye, H Tag: VC6 SP6 Tag: 265537

I have installed SP6 for VC6. This was done to deal with a problem
with the ios destructor issue referred to in KB814308. After
installing the service pack the file _ios.cpp was still the same that
was in previous service packs (date on the file, 2000-06-13). If you
refer to the individual knowledge base article it shows a file with the
date of 2003-02-05.
I was wondering does anyone have the hot fix that is referred to in the
knowledge base article. I have asked a support person at Microsoft as
we have an outstanding issue with named pipes and when he looked into
finding the hotfix he said that he was unable to locate it.

Thanks for any help

Allan McLellan
