    - How to find mem leak in output window? Dear all, When I stop running my application in debug mode, there are some mem leak detect info in output window like this: Detected memory leaks! Dumping objects -> {4925} client block at 0x00E5F768, subtype 0, 20 bytes long. a CVsInfo object at $00E5F768, 20 bytes long Is there anyway to check if my CVsInfo is leaking somewhere?

    - export a template method? Hi to everyone, In a VC6.0 project we have a class C which is exported in a dll. We added a template member function, say C::f<T>(T x) ///// C.h class IMPORT_EXPORT_DIRECTIVE C { // ... template <typename T> void f<T>(T x) { // body } }; since we only call f on a particular iterator, we added the following line(s) ///// C.CPP typedef std::multimap<double, long>::iterator mmiter_t; template void C::f< mmiter_t >( mmiter_t ); VC6.0 gives up (internal compiler error) on the forced instantiation line. We didn't try VC7.1 yet. It it the correct solution? -- Every idea yields an answer -- Abercrombie Smith Tag: How to find mem leak in output window? Tag: 212653

    - dialog items without MFC Hi there, I created a window project "without using MFC" and I added some Dialog boxes to the project with some controls included with them like combo boxes, check boxes, .....? How can I access these controls without using MFC? In other words, how can I change - for example - the check status of my check box or how I can upload and read from the combo box? I tried to use the class wizard to creat CDialog class but I got many lines of errors that one of them says that CDialog is undefined. I really appreciate your help.

    - How To Do This... I am just beginning to learn C++ so bare with me. I have a structure that looks like this: struct TEST_DATA { int Word1; int Word2; int Word3; bool Bool1; bool Bool2; }; And a variable declared as: TEST_DATA test_var; I need to share this variable data with another app using a Memory Mapped File. How do I do this? I have been reading stuff about MMF's but I guess I just don't understand it in C++. I can't figure out how to get the data into the MMF. I have done this in VB.NET successfully. The C++ app is actually a Win32 DLL. Thanks for any help! Tag: How to find mem leak in output window? Tag: 212620

    - dialog resource in library How do I make a Dialog resource (for DialogBoxParam) within a library available to any calling DLL or EXE? When I build a DLL that references a library that has an error message dialog, the DialogBoxParam fails with an error 1812 (dialog resource unavailable). If I include the .rc for the dialog in the DLL project, the dialog works. Is there some way, in building the library, that I can insure that the resource gets included in any calling DLL?

    - Compression algorithm question Hi, I've been reading in a stream of data from a data file where sometimes the data is uncompressed, and other times it is compressed. The uncompressed data is a list of longs - if I know there are 1001 data points, I do this: long* plArray = new long[1001]; DWORD dwRead; HRESULT hr = pStream->Read(m_plArray, 1001*sizeof(long), &dwRead); However, every now and then I come across a chunk of data where I know that I expect those 1001 data points, but the size of the data file is approximately 1/4 the size it should be (.ie. instead of being 4004 bytes, it might be say 1200 bytes). Its obviously been compressed - I'm guessing there's no encryption involved. There is a boolean just before the data stream starts that indicates whether compression has been applied or not, so I don't need to guess that based on the data size. If I know what the data _should_ be (I have a list of the what the unencrypted data is), could anyone gives me any tips/pointers as to what compression algorithm is being used? I'm new to this compression side of things. I'm just reading now about Shannon-Fano and Huffman coding for the first time. Maybe someone who's an expert wouldn't mind giving me a start in working out the algorithm applied. Thanks in advance, Alain Dekker Tag: How to find mem leak in output window? Tag: 212587

    - Inline ASM and OOP Hello, I wrote a pretty nice D3D framework in C++. Everything is done in classes and it all works great. Now I want to make a special version of it that is as small as possible. But I want to keep all the classes and basically maintain full compatibility with the "full" system. Some features will of course be left out, but otherwise I shouldn't have to change any code in the applications using the system. >From the beginning I already had this in my head so I can comment almost every feature out with a lot of #defines. And it gets a lot smaller. But now I want to push it to the limit using ASM. I figured I can decrease the total code size by at least a couple of k's when applying all my nasty tricks :) Anyway, I just got started and already ran into the first 2 problems: 1) I'm using VC6 and apparently imports aren't handled automatically when an API function is only called from an ASM block. Manually importing all functions seems a bit unnecessary so anyone knows of a better solution? 2) OOP. I know how to access data members of an object, but can't figure out how to call member functions. It seems MS's compiler wastes a lot of bytes for every "Object *bla = new Object()" so I'd really like to have that in ASM. But I have no clue how to call the constructor of the object. A sidenote.. Code readability is not really an issue here. My framework is in a stable state right now, and this small version is going to be for hacky 64k versions. This version of the framework will exist purely to get it as small as possible. Every dword counts :) I googled for quite a while now without getting any usable results. Hope someone here can help me :) /Nico Tag: How to find mem leak in output window? Tag: 212541

    - Template Member Function Parameters I have some code from an open source project I'm trying to port to VC6 SP5 I'm having trouble passing a parameter to a template member function. I'm not new to templates, but this one goes a bit deeper then I've ever delved. Here's the watered down version: Two simple classes, one inherits from the other, and the template class. ======== class test { public: test(); }; class test2 :: public test { public: test2(); }; template <class P> class MPtr { public: MPtr(); ~MPtr(); template <class Q> friend bool myFunc(const MPtr& p) { return 0; } }; ===== Now, when I do: ===== MPtr<test2> a; is_a<test>(a) ====== VC++ gives the error: error C2670: 'is_a' : the template function cannot convert parameter 1 from type 'class MPtr<class test2>' Any ideas? I know this compiles with gcc, because that's what this code is from. I'm sure this is come VC specific problem, and if so, is there a workaround? Thanks.

    - can't see debug information after program crash on XP I'm running my code in VC++ 6.0 on WinXP under debug mode. Every time it meets memory error, e.g. access violation, a messagebox popup, then I choose "debug", another messagebox popup saying some address can't be read. After click on the "ok" button, every active window will be shut down and I can't see which line of code cause the problem. In other platform than XP, the debugger will stop at the line cause the problem. What's wrong with XP? Any suggestion? Thanks. Tag: How to find mem leak in output window? Tag: 212519

    - Visual C++ 6 non-inline member function in template'd class I have the following class: template<class DynObject, class ElementType = int> class SmartPtr int operator== (const SmartPtr & _dynObject); }; With the following externally defined member function (i.e. non-inline): template<class DynObject, class ElementType> int SmartPtr<DynObject, ElementType>::operator== (const SmartPtr & _dynObject){ if (m_dynObjPtr == _dynObject.m_dynObjPtr){ return 1; } return 0; } When I attempt to invoke my smart pointer's (SmartPtr's) equivalence test overload I get the following linker error: MainEntry.obj : error LNK2001: unresolved external symbol "public: int __thiscall SmartPtr<class Test,int>::operator==(class SmartPtr<class Test,int> const &)" (??8?$SmartPtr@VTest@@H@@QAEHABV0@@Z) Debug/TimDynamic.exe : fatal error LNK1120: 1 unresolved externals When I take the member function out of the .cpp file and put the entire definition back into the class declaration (i.e. inline the member function): int operator== (const SmartPtr & _dynObject){ if (m_dynObjPtr == _dynObject.m_dynObjPtr){ return 1; } return 0; } It works fine. Is this a known problem with MV C++'s compiler? Or am I doing something wrong with this member function definition? Also, is it possible I'm not "feeding" the compiler some necessary switch? I've disabled optimization in the hopes that would fix it - but it doesn't. Thanks, Novice Tag: How to find mem leak in output window? Tag: 212509

    - DLL and calling convention Hi, I am having an issue with creating a DLL with calls to (among other things) the C standard library within. I have reduced my problem to the following pieces of code: /***************** dll.c ***************/ #include <stdio.h> #include <stdlib.h> int dt_read(FILE *f) { int status = EXIT_FAILURE; char buf[100]; if (f != NULL) { if (NULL != fgets(buf, sizeof buf, f)) { buf[sizeof buf - 1] = 0; puts(buf); status = EXIT_SUCCESS; } } return status; } /****************** end of dll.c **************/ This code is compiled and linked into a DLL with the following .def file: /*************** begin dll.def ****************/ LIBRARY DLL DESCRIPTION "dll test dll" VERSION 1.0 EXPORTS dt_read /*************** end dll.def *******************/ Then another application uses the code (dynamically linking to the DLL) as follows: #include <stdio.h> #include <stdlib.h> #include "dlltestdll.h" int main(void) { int status = EXIT_FAILURE; FILE *f; f = fopen("main.c", "r"); if (NULL != f) { char buf[100]; if (NULL != fgets(buf, sizeof buf, f)) { buf[sizeof buf - 1] = 0; puts(buf); } status = dt_read(f); } fclose(f); return status; } As the code shows, there are two similar calls to fgets, one from the program itself, and the other one from the DLL. While the first call succeeds, the second one fails somewhere deep into fgets. I can only imagine that this is cause by some corruption due to bad calling conventions, but am at lost as to how to correct/manage it. Any hints ? -- Bertrand Mollinier Toublet int main(){char*strchr();int j=1234;char t[]=":@abcdefghij-lmnopqrstuv" "wxyz.\n",*i="iqgbgxmbbla.llsvoaz:zdxylaxejivnidhd@ttopnjeftuh-i";while (*i){j+=strchr(t,*i++)-t;j%=sizeof t-1;putchar(t[j]);}return 0;} Tag: How to find mem leak in output window?

    - Keyboard input Hi, I have a program which controls the mouse and keyboard by installing system hooks. Both are controlled via pre-recorded data and call SendInput based on this data. The data consists of nothing more than what key was pressed, where the mouse moved, etc. What I'm looking for is a way to disable the user from physically pressing any keyboard button except escape. I found BlockInput in MSDN, which would be very useful, except it disables all physical input. Is there a way to detect if the user physically pushed a button on the keyboard, rather than sending SendInput messages, or WM_KEYDOWN? Thanks for any suggestions!

    - Is it possible to make a MFC dialog In-Proc when called from and ATL COM from VB? Hi, I have an ATL COM object that contains a MFC Dialog. One method of my ATL must allow me to display the dialog in modal (DoModal). I use this ATL COM in my VB app. I want to call the ATL Method from my VB app to make the MFC dialog appear in modal. The problem is : The dialog appears, but is not in-proc. So I receive a message each time I click on the parent window (not a beep sound, but really a message). Is it possible at all to make my dialog appear in-proc or it is a limitation of the COM (or VB) usage? Someone talked to me about In-Proc server, but I really don't understand this concept. I don't understand why calling 2 methods make my dialog out-of-proc. Can someone explain it to me plz? Thanks ThunderMusic P.S.

    - Newbie question: Calling VB function from a C DLL w/out crashing VB I have been scratching my head for several hours now trying (yet again - gave up the first time) to successfully call a Visual Basic function from a C DLL, place a watch on a string passed ByVal, and exit the function ALL without crashing VB. As long as I don't actually look at the contents of the passed string, it works great! Soon as I look at it, though, VB up and dies _after_ exiting the VB function. Does anyone know how to do this? I've tried it using character pointer, BSTRs, user-defined data types, and nothing works. I've tried allocating memory for the BSTRs using SysAllocString and not freeing the memory using FreeSysString (and flip-side calling FreeSysString) and nothing works.

    - Clipboard problem again I under stand that "The data for private clipboard formats is not freed by the system when the clipboard is emptied. Therefore, the clipboard owner should free the data upon receiving the WM_DESTROYCLIPBOARD message. For more information about private clipboard formats, see Clipboard Formats." And i freed the global memory if (globalMemHandle) { HGLOBAL temp = GlobalFree(globalMemHandle); globalMemHandle = 0; } the "temp" is NULL after this but still if i copy a bitmap in a loop the system memory keep on decreasing. And it is eating the system perfomance .. The Application which i am working on is a Bitmap editor which will crash after a continuos copy of a bitmap.. Can somebody help on this.

Dear all,
When I stop running my application in debug mode, there are some mem leak
detect info in output window like this:
Detected memory leaks!
Dumping objects ->
{4925} client block at 0x00E5F768, subtype 0, 20 bytes long.
a CVsInfo object at $00E5F768, 20 bytes long
Is there anyway to check if my CVsInfo is leaking somewhere?
Thanks
