    - Dialogbox did not show up. Please help!!! Hi, I am implementing a Win32 DLL project. In this dll I developed a dialogbox. In order to export the dialogbox, I did the following things. 1. define a function called Test() int Test() { return DialogBox(NULL, MAKEINTRESOURCE(IDD_DIALOG),NULL, DlgProc); } 2. export this Test() function. The problem I encountered was the dialogbox did not show up. The DialogBox() returned a -1 indicating it failed to create the dialogbox. So I called GetLastError() and got the error code 1812, which indicates "The specified image file did not contain a resource section.". I am pretty sure the Test() function was successfully exported because I got some results if I replace the DialogBox() with other functions. I stuck there for tens of hours so if you have any clues or ideas, please drop me a line. I deeply appreciate your help. THanks, Hu Tag: Get Accont type. Tag: 232717

    - Static libs Hello all ! I want to create a static lib. In it, i'm calling a function (lets say 'xzy') that is in another static lib... So I included it in the project and I compiled... it compiled fine.. When I write a client that uses my lib, it complains that it cannot link the 'xyz' function (unresolved)... So the client have to include the lib where 'xzy' is implemented... Is there a way for the function body 'xyz' be included in my static lib so that clients that will use my lib won't have to include all other libs that my lib uses !? Mike Tag: Get Accont type.

    - Slow file transfer ... Hi, I am writting a program using WinSock2 to transfer files, the program seems work fine when the file is not that big. But when I tried it with a 370M file, it's too slow that I can tell the transferrred file increase it's size about 1200byte each time. I used TransmitFile() in putting file, here is how I use the function: if(!TransmitFile( m_socket, hFile, 0, 0, NULL, NULL, 0 )) { CloseHandle(hFile); throw CCException( CWsaerr(), WSAGetLastError(), _T("Falied to transmit file") ); } I am not sure if the slow transfer is from this function call. Even I increase the buffer size of receiving side (I used recv() ), it seems no effect. So I suspect it. One of my collegues said MTS may limit the transfer to about that speed, but I am not sure. Any idea? If TransmitFile() does cause this slowing down, any ways to fix it? Or I have to go back to use traditional send() to send? Any comments or suggestions? Thanks, Peter Tag: Get Accont type.

    - deadlock on SMP machines - perhaps caused by wldap32.dll? Hello, Apologies in advance, this is a very long post, but I'm trying to be as complete as possible. I'm also not sure if this is the correct group, but it seemed appropriate. We have a process that runs as part of our product that has been working fine on Windows. However, we recently had an issue onsite where these processes (there are usually multiple instances) would hang and become completely unresponsive on SMP (Compaq 8-way) machines running Windows NT and 2000. I've managed to recreate the issue in our test lab on a dual Xeon (hyperthreaded) box running Windows 2003. There is definitely some sort of deadlock situation here, but I'm at a loss how to proceed after banging my head against this for a week now. There is some evidence that suggests the DllInit function of wldap32 is somehow a player in this - the details are further down. First, let me provide a little context: This service (it's not really an application) is written in VC++ 6.0, and is spawned via a daemon that is also part of our application. In a typical deployment there is one of these service processes for each processor on the local machine. The service instantiates a Java Virtual Machine via JNI, and most of our core code executes within the VM. One of the functions of this service is to spawn processes and feed them input and capture their output. This is acheived by the VM loading a VC++ 6.0 bridge library, which in turn loads another VC++ 6.0 library (we'll call this the "work library") which does the actual work. When all of the assigned work is through, the work library is unloaded until the next time. The work library is fairly simple, and the core behavior involves invoking CreateProcess (usually cmd.exe, which in my test setup just echoes some msg), and creating threads to write to the input handle, and read from the output and error handles. This has been working on all flavors of Windows (uniprocessor) for quite some time. Now, to the details. Here is the basic sequence leading up to the hang: 1) Process loads the work library 2) Process performs some number of brief "work units" (CreateProcess() + accompanying threads, and then cleanup) happily and healthily 3) Process CPU utilization drops to 0, and there is no more activity, ever. This lockup appears to happen faster when more instances are running. Attaching cdb to these hung processes consistently reveals two scenarios: Scenario A - the "Is wldap32.dll doing something bad?" scenario ---------- The work library thread which called CreateProcess has successfully waited on the process to exit. It waits on an Event that will be set by the thread which reads the output from the process, but that Event is never set. Mainly because those helper threads are stuck. The debugger always has to forcibly break into the process b/c the loader lock is held. !locks reveals two locks in contention: CritSec ntdll!LdrpLoaderLock+0 at 77FC2340 LockCount 8 RecursionCount 1 OwningThread b80 EntryCount 2a ContentionCount 2a *** Locked CritSec WLDAP32!PerThreadListLock+0 at 76F34010 LockCount 1 RecursionCount 1 OwningThread d64 EntryCount 1 ContentionCount 1 *** Locked ---- Stack trace for thread b80: 0f5dfba8 77f43741 77f5d64e 000005a0 00000000 SharedUserData!SystemCallStub+0x4 0f5dfbac 77f5d64e 000005a0 00000000 00000000 ntdll!ZwWaitForSingleObject+0xc 0f5dfbe8 77f42044 000005a0 76f1129f 76f34010 ntdll!RtlpWaitForCriticalSection+0x126 0f5dfbf0 76f1129f 76f34010 00000000 0f5dfc1c ntdll!RtlEnterCriticalSection+0x46 0f5dfc00 76f11257 00000b80 77f47dc9 76f10000 WLDAP32!AddPerThreadEntry+0x2f 0f5dfc08 77f47dc9 76f10000 00000002 00000000 WLDAP32!LdapDllInit+0x3e 0f5dfc28 77f5d067 76f11180 76f10000 00000002 ntdll!LdrpCallInitRoutine+0x14 0f5dfcbc 77f5cef6 0f5dfd30 0f5dfd30 00000000 ntdll!LdrpInitializeThread+0xd4 0f5dfd1c 77f45241 0f5dfd30 77f40000 00000000 ntdll!LdrpInitialize+0x171 00000000 00000000 00000000 00000000 00000000 ntdll!KiUserApcDispatcher+0x7 To me, this begs the question: why is this library referred to in the first place? We certainly don't use LDAP and we aren't using ActiveDirectory, either. 'lm' reveals that it is an unloaded module. My only guess is that the library init routine is called in order to see if LDAP is enabled in case it's needed to check process/thread creation security tokens. The interesting thing about WLDAP32!PerThreadListLock+0 is that the owning thread (d64) is nowhere to be found! So, no stack trace. There are several other threads waiting on locks. None of them are in my input/output/error read/write user code, they are all in LdrpInitialize or kernel32!ExitThread. I suspect the exiting threads are mine. 5 threads have the same trace (with differing addresses, but waiting on the same critical section - 77fc2340): 0f6dfbec 77f43741 77f5d64e 00000330 00000000 SharedUserData!SystemCallStub+0x4 0f6dfbf0 77f5d64e 00000330 00000000 00000000 ntdll!ZwWaitForSingleObject+0xc 0f6dfc2c 77f42044 00000330 77f5cfcc 77fc2340 ntdll!RtlpWaitForCriticalSection+0x126 0f6dfc34 77f5cfcc 77fc2340 00000000 7ffdf000 ntdll!RtlEnterCriticalSection+0x46 0f6dfcbc 77f5cef6 0f6dfd30 0f6dfd30 00000000 ntdll!LdrpInitializeThread+0x2f 0f6dfd1c 77f45241 0f6dfd30 77f40000 00000000 ntdll!LdrpInitialize+0x171 00000000 00000000 00000000 00000000 00000000 ntdll!KiUserApcDispatcher+0x7 And here are the exiting threads: c18: ---- 0e0dfe70 77f43741 77f5d64e 00000330 00000000 SharedUserData!SystemCallStub+0x4 0e0dfe74 77f5d64e 00000330 00000000 00000000 ntdll!ZwWaitForSingleObject+0xc 0e0dfeb0 77f42044 00000330 77f7c658 77fc2340 ntdll!RtlpWaitForCriticalSection+0x126 0e0dfeb8 77f7c658 77fc2340 00000000 7ffa4000 ntdll!RtlEnterCriticalSection+0x46 0e0dff44 77e57eb3 00000000 0c0bd418 00a87b88 ntdll!LdrShutdownThread+0x30 0e0dff7c 77bc917d 00000000 77bc91f3 00000000 kernel32!ExitThread+0x41 0e0dff84 77bc91f3 00000000 00000000 00000000 msvcrt!_endthreadex+0x25 0e0dffb8 77e4a990 00a87b88 00000000 00000000 msvcrt!_endthreadex+0x9b 0e0dffec 00000000 77bc917e 00a87b88 00000000 kernel32!BaseThreadStart+0x34 9cc: ---- 0e1dfe70 77f43741 77f5d64e 00000330 00000000 SharedUserData!SystemCallStub+0x4 0e1dfe74 77f5d64e 00000330 00000000 00000000 ntdll!ZwWaitForSingleObject+0xc 0e1dfeb0 77f42044 00000330 77f7c658 77fc2340 ntdll!RtlpWaitForCriticalSection+0x126 0e1dfeb8 77f7c658 77fc2340 00000000 7ffa3000 ntdll!RtlEnterCriticalSection+0x46 0e1dff44 77e57eb3 00000000 0b2e6c48 0b38b590 ntdll!LdrShutdownThread+0x30 0e1dff7c 77bc917d 00000000 77bc91f3 00000000 kernel32!ExitThread+0x41 0e1dff84 77bc91f3 00000000 00000000 00000000 msvcrt!_endthreadex+0x25 0e1dffb8 77e4a990 0b38b590 00000000 00000000 msvcrt!_endthreadex+0x9b 0e1dffec 00000000 77bc917e 0b38b590 00000000 kernel32!BaseThreadStart+0x34 I can provide further information if it is needed. ------------------------------------------------------------------------------- Scenario B - the "what happened to the malloc lock?" scenario ---------- As in scenario A, the work library thread which called CreateProcess has successfully waited on the process to exit.

None of the other threads reveal anything interesting. ------------------------------------------------------------------------------- Summary: I considered the possibility of heap contamination, but using gflags I enabled full page heap and every other form of heap checking, but there appear to be no problems there. I am suspicious that there is something else at work because these scenarios happen exactly the same every time. As I mentioned before, this code has been working perfectly on Windows uniprocessor systems for more than a year now. The only variable is the multiprocessor environment. I am seriously thinking that this is system related. I've noticed that there have been some deadlock related fixes for wldap32.dll, including a recent hotfix that postdates the release of Windows 2003. I'm wondering if this would fix our problem? I eagerly await any new ideas on this issue! I am pretty much out of them at this point. If I can provide further information on this, please ask. Thanks for reading!

    - Can rebasing affect correctness of information in the map file generated before? Hi everybody For some strange reasons offsets in dlls loaded into memory do not match those, mentioned in map file. We suspect that this happens due to automatic rebasing of all the binary modules involved in workspace at the end of complete build of all the projects. Can this possibly be the case and how to avoid it? It looks like order of some sections is changed. Quite often offsets exceed the last offset mentioned in the map file. We generate map file with options /map /MAPINFO:LINES /MAPINFO:EXPORTS during building of a particular project. Rebasing is made after all the projects were built and involves all the modules that will be loaded: rebase.exe -b 0x60060000 [module ...] Kind regards, Antonio Tag: Get Accont type. Tag: 232682

Swapping with an empty vector, clearing the vector, resizing it to 0, all are good attempts to accomplish what you need, but the Standard makes no promises WRT the memory allocation behaviour.

    - Which interfaces should be referenced in coclass definition of idl file? Hi everybody, Is there any rule or principle based on which one can decide which interfaces from those supported by the object to include into coclass definition and which not?

    - DLL with imports that should be used from different mainprogr Dear Gurus, I am on MSDEV 6.0 working from the command line. My Code is C Code. I am trying to generate a DLL that imports symbols from a main program. The DLL should be used by different main programs that all export the same symbols. The usual approach, if the DLL is only used by one main program would be to simply link the DLL against the export library of the main program. However if I do exactly that, then the other main programs will crash with the DLL when the DLL calls functions from the main program. (the reason being that the dll has somehow incorporated the name of the main program of which the symbols were imported at DLL link time). So how can I properly create a DLL that imports symbols from the main program without telling the DLL anything else then the names of the symbols that will be imported? And how can I tell the DLL the imported symbolnames without using the export lib of a main program? thank you very much for any insights Wolfgang Tag: Get Accont type. Tag: 232657

    - array of handles arithmetic C, win32, VC7 Suppose I have an array of handles, like this: HANDLE* thread_handle; int max_threads; ... max_threads=256; ... thread_handle=calloc(max_threads, sizeof(*thread_handle)); if (thread_handle==NULL) return 1; There are more handles than a function like WaitForMultipleObjects can use. http://msdn.microsoft.com/library/en-us/dllproc/base/waitformultipleobjects.asp The handles may point to threads that have already done _endthreadex(0), there are never more than 64 threads in existence at the same moment. Threads are usually short lived (they wait for a UDP network answer). The maximum amount of thread handles is 64, but there may be up to 256 used. Is it possible to point to the 65th, 129th, 193th handle and run that function again? You can do this with strings because they are contiguous array of bytes, but does it work the same way with handles? May be I'm doing something stupid here, help is appreciated.

    - How to check from destructor whether it was called due to exception or normal exit from the scope? Hi, everybody Is there a reliable way of detecting whether destructor of a local object was called due to stack unwind (exception) or normal exit from the scope? This check has to be made inside destructor of this local object. If there is no portable C++ way of doing this, hacks for Windows and/or MSVC6 generated code (with checking some registers etc.) will do. Thanks in advance, Antonio Tag: Get Accont type. Tag: 232646

If you are working on an MFC application having a frame, seeing the following statement is not uncommon: cs.style &= ~FWS_ADDTITLE; // remove extra stuff from title My question is, why is the value simply not subtracted like: cs.style -= FWS_ADDTOTITLE; The resulting style is the same for both.

    - clock() Is it a known issue that in VC++ RTL the function 'clock()' reports the wall clock instead of CPU time used?

It seems that on Windows it just takes the time() at the beginning and then 'clock' simply takes the difference between current time and the stored value and multiplies it with CLOCKS_PER_SEC... I know of GetProcessTimes() function, but couldn't 'clock()' be implemented to use it? Thanks. Victor Tag: Get Accont type. Tag: 232556

    - BUG Report: Failed When a Native Event is Unhooked with with Multi-Heritance Hi, i need to use the native event in a ATL/WTL C++ application. I found out there was some error in the __unhook generated code when your receiver has multi-heritance __unhook fail in these case to find the right hook to delete, and doesnt. It leaks memory and the hook isnt removed so if you __raise, you keep getting the event. To work around this problem, use the following method: native_event.cpp: #include <stdio.h> class A { int a; }; class B { int b; }; [event_source(native)] class CSource { public: __event void MyEvent(int nValue); }; [event_receiver(native)] class CReceiver : public A, public B //multi-heritance { public: void MyHandler1(int nValue) { printf("MyHandler1 was called with value %d.\n", nValue); } void MyHandler2(int nValue) { printf("MyHandler2 was called with value %d.\n", nValue); } }; int main() { CSource source; CReceiver receiver; __unhook(&CSource::MyEvent, &source, &CReceiver::MyHandler2, &receiver); __hook(&CSource::MyEvent, &source, &CReceiver::MyHandler1, &receiver); __raise source.MyEvent(1); __unhook(&CSource::MyEvent, &source, &CReceiver::MyHandler1, &receiver);//failed __hook(&CSource::MyEvent, &source, &CReceiver::MyHandler2, &receiver); __raise source.MyEvent(2); __unhook(&CSource::MyEvent, &source, &CReceiver::MyHandler2, &receiver);//failed } Compile: cl /Fx /Fas native_event.cpp Result: MyHandler1 was called with value 1. MyHandler2 was called with value 2. MyHandler1 was called with value 2. MyHandler2 can't be unhooked。 Applies to: Microsoft Visual C++ .NET (2002) Microsoft Visual C++ .NET (2003) Visual C++ 2005 Express Edition Beta solution: To solve this problem we can change native_event.mrg.cpp from int __isEqual(void* p, void* pfn) { return ((T*) p == this->p) && (__eventingGetAddr<T>::__getMAddr(pfn) == (void ( T::*) ()) pmfn); } to: int __isEqual(void* p, void* pfn) { return ((T*) p == this->p) && pfn == __eventingGetAddr<T>::__getVAddr((void (T::*) ()) pmfn)); } But, I don't know what is the best soluction.

I'm using FtpGetFile() repeatedly to copy a folder structure that contains 222 files (total 27Mb), of which one file is 17Mb and the rest are smaller. The 17Mb file is one of the first (#8) to copy, and it does OK, but after 14-80 files are copied (around 18-19 Mb) I get error code 12003 from the first file that fails, then 12030 from subsequent files. Codes in the 12000 range are not included in my message list in either environment, so I don't know what this error means. Questions: 1. What do error codes 12003 and 12030 mean? (I can't find them in MSDN or CE Help). What is actually failing here? 2. Is there any way to get the WinInet error messages (I've seen other Ftp routines report 12xxx error codes) included in my XP and CE environments? I thought maybe this was a limitation of our FTP site, but our IT group says they can copy Gbs of data with no problem. I tried skipping over the 17Mb file, and the other 221 files (10Mb) copy just fine. Then, even more mysterious, I tried copying the 17Mb file last (after the other 221), and that works fine as well! Any ideas? Can I depend on the workaround of copying the biggest file last always working? Thanks, Michael Schwab Tag: Get Accont type. Tag: 232482

I am writing a plugin based program. i have 2 interfaces (abstract classes) IPlugin and IPluginMenu, all plugins inherit from IPlugin but plugins that need menu need to inherit from IPluginMenu and implement OnMenu which is pure virtual. Now in my SDK I have a function called SetPluginMenu and there as a parameter I want to pass a instance of class that inherits from IPluginMenu, but the problem is that I also need to make sure that caller also inherits from IPlugin, so that someone inheriting only from IPluginMenu won't be able to call SetMenu as he has to inherit from both classes.
