    - Size of int (once again, sorry) Hi, sorry about the multiple posting, technical difficulties.... ----- What does exactly the size of the int datatype depends in C++? Recenlty I've heard that it depends on the machine's type, i.e. on 16-bit machines it's 16 bit, on 32-bit machines it's 32 etc. Is this true? Is this true for _all_ C++ compilers?

    - Minimum pane size in a CSplitterWnd Hello all, I am using a CSplitterWnd. I would like to prevent the user from dragging the splitter any closer than a certain distance from the edge of the window. I found that CSplitterWnd::SetRowInfo() and CSplitterWnd::SetColInfo() allow you to set a "minimum" size. However, it's not the case that the user can't drag the splitter past this minimum. It's just that if he does so drag the splitter, the window size will become 0. Is there a way to do what I wish and pysically disallow the splitter to move past a certain point?

    - Multiple threads using COM I'm writing an ATL service which creates a COM object that is accessed from two separate threads. I call CoInitialize before I call CreateInstance, when I call CoInitializeEx and pass MULTITHREADED, I am unable to use the COM object although CreateInstance returns S_OK. The problem is when I create the second thread and try to use the shared COM object (using critical sections), it fails, and I donâ??t know how to fix it. How can I have two threads use the COM object? Thanks Mark Tag: Complete Tutorial or Sample of MSLU Tag: 236243

    - Binary searching Hi, I try to implement the following in C: My application receives a buffer that is of type BYTE* and is filled with both ANSI strings and binary content in between. Now, the problem is, that I want to search for specific patterns in this buffer - _lsearch does this just perfectly well. Now, as the buffer also 'contains' strings (of course not in that format, but by content) I want to do both case sensitive and case insensitive searching on that. As the buffer might contain NULL values I cannot use any typical string function. Any ideas how to do that in a different way? Thanks a lot Peter Tag: Complete Tutorial or Sample of MSLU Tag: 236239

    - Ternary Search Trees In making a ternary search tree to identify as fast as possible the type of word passed in to the algorithm, for instance sp_help -> 1 (procedures), select -> 2 (keywords), sysobjects -> 3 (system tables), I'm stuck on deciding what type of comparison happens at each node. Has anyone got any suggestions? Do you think for the first level I could compare just the first characters of the word passed in and the word at the 'current' node, or would it be more likely to be a whole word comparison for each node? If it would be a whole word comparison, what form would this take for best performance? Bearing in mind that each word will only ever return the same type, but more than one word will have a certain type (i.e. the type will not be unique, but the word will.)

    - Can't determine cause of heap corruption or orphaned lock using cdb Greetings, I posted on this issue before, in a more complex environment, and thought I had resolved what appeared to be an orphaned lock or heap corruption in my application by removing a call to TerminateThread(). You can see the original thread here: http://groups.google.com/groups?hl=en&lr=&ie=UTF-8&c2coff=1&safe=off&threadm=f867e9d7.0407151302.7f0882eb%40posting.google.com&rnum=2&prev=/groups%3Fq%3Dmarc%2Belliott%2Bpush%2Bdirection%26hl%3Den%26lr%3D%26ie%3DUTF-8%26c2coff%3D1%26safe%3Doff%26selm%3Df867e9d7.0407151302.7f0882eb%2540posting.google.com%26rnum%3D2 However, I am still experiencing this issue. When I launch my app (particularly one which does a high number of calls to CreateProcess() and creates runner threads for stdin/stdout/stderr the process hangs or (more rarely) faults on closing Invalid Handle or something similar. Sometimes I will get this problem after a single call to CreateProcess(). I've been through the process spawning code a million times, but I don't see anything untoward. I've enabled full page heap and the lock verification layer, and although app verifier throws exceptions in places that appear to be during access to invalid handles, etc, I don't see anything otherwise meaningful and there are times where the process still hangs and AppVerifier doesn't seem to notice anything's wrong at all. Question: What can I do to better isolate the problem using these tools? I am able to repro on Win2K3, so I have access to the latest AppVerifier switches, but am at a loss as to what usefulness I can get out of them at this point. Further details: This issue only appears on SMP boxes, and I have only had success repro'ing it when multiple instances of the process are running simultaenously. Whether that indicates some resource contention or simply increases the statistical likelihood of the error appearing is unclear. Any suggestions from the cdb/windbg masters are heartily welcomed!

    - Which memory allocator to use? Hello all, needing to allocate a large number of buffers (let's say 20.000 buffers of sizes between 8 and 200 bytes), which method would you recommend: 1. malloc (slow from my tests) 2. dlmalloc (Doug Lea's malloc replacement) 3. other Since there are so many ways to alloc buffers, which is the one you would recommend in terms of performance (e.g. GlobalAlloc, LocalAlloc, IMalloc, malloc etc.) If your solution is a custom memory allocator, I need it to work on Win32 (e.g. Win9x included). I've done tests with dlmalloc and it seems pretty fast. Perhaps an experience/advice of using it in the real-world would help. Thanks.

    - SetTimer / static pointer Hi All, Two questions.. one about SetTimer and the other one about a static pointer.... I have a problem w/ the CWnd::SetTimer function. Maybe someone can give me an insight. This question regards a Windows CE [3.0] device: Let's say I have a timer running in my main dialog window started by "SetTimer(ID, .. etc)" .. then, I display modally a new window on top of the main one. In this one, I start a new timer by the same function "SetTimer(ID, ...") where the ID of this timer in this newly displayed window is different than the ID from the main window (even though the documentation says that the IDs can be the same given that these timers are ran in two different windows... but just to make sure.) What happens is that sometimes the timer from the second window quits working (no WM_TIMER message is generated for that window) IF the timeout values of the two timers are the same. If they are different by even 2ms, the problem never occurs but if they are the same, the problem can almost always be reproduced. The weird thing is that if I start a 3rd timer, on a 3rd window displayed modally, then the 2nd timer may start firing as well (this 3rd timer would have a different timeout value than the other two), but as soon as I kill this third timer, then the 2nd timer dies again...Note that the SetTimer functions return success in all cases [for all 3 timers.]... Has anyone experienced a problem like this ? The second questions is this: In a certain class, in the header file I have: static CSomeObject* c_pTheObject(); Implemented as: CSomeObject* TheClass::c_pTheObject() { static CSomeObject* pKeyPad = new CSomeObject; return pKeyPad; } This is really simulating a "static" object which I want to make sure it is actually created before I use it so whenever I need it (maybe in different translation unit) I do something like: TheClass::c_pTheObject()->SomeMethod(); this way, if the object is not already created, then it is created before being used... if it is, it just returns a pointer to the already existing object so everything is ok... When deallocating it, I do something like: delete TheClass::c_pTheObject(); Is this correct ? I am thinking that using c_pTheObject() will return me a pointer to the already existing object (as described above) and the delete statement will delete the object that the pointer points to... I tested this approach by checking if the destructor of the CSomeObject is being called when calling the delete TheClass::c_pTheObject() and indeed it is called... Thanks for any tips/suggestions.

    - HOWTO?: Function Pointer to Instance Member Hello, I need to form a function pointer to a function in an instance of a class. The docs say that the way to call a member function from outside the class is: void (A::*p4)() = &A::f; But doesn't that require the function to be Static? I would like to be able to use an instance function. Further, is it possible to make the function pointer so that its declaration does not have to specify the class of the function I wish to call - can it specify only the return type and parameter list? I know this is complicated, thank you for reading through it all and trying to help! Thanks, Rich PS. The reason I want to make a pointer to an instance member is so that I can call this function in a variety of different objects, generically. Tag: Complete Tutorial or Sample of MSLU Tag: 236204

    - Problem returning string from DLL function I have a function in a DLL which returns a std::string - When I call it from my main program I'm getting exceptions after the call to the function saying that the heap is broken. I seem to remember a long time ago reading that there were problems sharing STL objects between a main program and a DLL but I though this had been fixed in vc.net 2003. Is it likely that having a std::string as the return type of my function in the DLL is the problem, and if so is there anything I can do to make it work?

    - newbee: trouble w/ try{} catch{} There is a tool that we use here at work. The guy that wrote it has since quit and I was asked if I would like to take it over (I'm learning to program and the co. supports that) with that said, the code is really messy and rather than fix ir "correct" i have started to design a new version from the ground up, I am still responsible for keeping the old one running until I roll out the new one. OK, so I have a crash that happens randomly and I have asked the people here to send me their logs when they crash, I have narrowed it down to one operation and I don't understand why it's happening. I just thought I could wrap it in a try/catch and handle it from there. Here is the code: inline byte GetRecordTypeId(void* pV) { if(pV) { try { return *(byte*)pV; } catch(char* e) { theLog.WriteError(e, __FILE__, __LINE__); } } return kRecordTypeUndefined; } However, this appears to do nothing. It still crashes just the same as if there was no try block. From what I understand, the above code should have worked fine. What am I missing? For testing purpose I forced a crash in the code by setting the void* to an int (pV = (void*)someInt;) Any help or suggestions would be great. Thanks!

The relevant (I hope) code follows: namespace string_t { template <class T> class StringT { public: friend StringT<T> operator + (const T * pszString, const StringT<T> & String); }; template <typename T> StringT<T> operator + (const T * pszString, const StringT<T> & String) { StringT<T> Result; return Result; } template class StringT<char>; } // end namespace string_t using string_t::StringT; typedef StringT<char> String; int _tmain(int argc, _TCHAR* argv[]) { String First; String Second; Second = "String constant " + First; return 0; } Thanks, Brian Tag: Complete Tutorial or Sample of MSLU Tag: 236128

    - how to export this function? hi, all I wrote a dll, but , it does not work correctly. I created a Regular DLL using shared MFC DLL in vc6 and exprots one function // in mydll.cpp CString __cdecl GetStringCode(CString str1, CString str2); CString __cdecl GetStringCode(CString str1, CString str2) { //code..... CString strRet = ........ return strRet; } // in mydll.def file EXPORTS ; Explicit exports can go here GetStringCode @1 // ----- Use it in another Dialog Based app typedef CString (FAR __cdecl *PGetStringCode)(CString str1,CString str2); HMODULE hLibrary; hLibrary = LoadLibrary("win98type.dll"); if(hLibrary != NULL) { PGetStringCode pGetSC = (PGetStringCode)GetProcAddress(hLibrary, "GetStringCode"); if(pGetSC != NULL) { CString str = pGetSC("1","2"); //Here, I debugged into the mydll, int function GetStringCode(str1, str2), the str1="2" , str2="", this is not right. FreeLibrary(hLibrary); } } So how to export this function? What is wrong here? Thanks Tag: Complete Tutorial or Sample of MSLU Tag: 236124

    - using VC6 libs with VC7.1 Hi, I got a problem here. I have some libs compiled under VC6. I am trying to link to them using .NET which has VC7.1. But I have the following linking errors: error LNK2005: "public: __thiscall std::locale::locale(void)" (??0locale@std@@QAE@XZ) already defined in SOMEFILE.lib(SOMEOTHERFILE.obj) error LNK2019: unresolved external symbol "void __cdecl std::_Xlen(void)" (?_Xlen@std@@YAXXZ) referenced in function _$E30 error LNK2001: unresolved external symbol "void __cdecl std::_Xran(void)" (?_Xran@std@@YAXXZ) error LNK2001: unresolved external symbol "void __cdecl std::_Xran(void)" (?_Xran@std@@YAXXZ) From reading the web, it seems the errors are due to the compatability between VC6 and VC7. The fundamental problem here is I don't have access to sources and have access only to the VC6 libs. Is there any workaround/solution to solve this problem? Thanks a lot.

    - Strange behaviour of linker (vc++) Hi, I'm using visual studio 2003. I have one workspace consisting of several projects (resulting in static libs) and one project giving me an executable (this one depends on all the other projects). Now i've got one project that just has one c++ file like this: ----- static int foo = somesingleton::instance().dosomething(); some other functions(); ------ Neither my executable nor any other of the libs reference anything in this c++ file. Now my problem is that the linker does for some reason not link said file into my binary. The static initialisation never happens. If, however, I do reference something else from this file in some other place then it gets linked in. To me it looks like the Linker tries to get rid of unneeded symbols and does a horrible job at this (since this symbol _is_ needed). Any ideas on how to fix this? I do not want to reference anything from this file in any of my other files, i just want to have it linked into my executable. I do not want to add autostart hacks to the crt. kind regards Philip Tag: Complete Tutorial or Sample of MSLU Tag: 236085

    - Can objects have properties? I'm using VC++ v8 beta. Haven't used VC++ for many years, v4. Can I create properties in a plain old class (non-visual)? I've been using Borland C++ Builder for many years. There, one can create public properties with setter/getter functions that can set/get a private variable as well as execute additional code which may change the state of the object.

Dear All,

I wrote a Unicode Program with VC2003 on WinXP, I want my program to support
Win98 also. So, I find document and I know that MSLU can be my solution.

But I think it is not so easy for me. Therefore, I am seeking tutorial
document to teach me.

Does anyone know where can I get it?

Thanks.
Kevin Tang.
