    - Why not to save the source file in VC ++ 6.0? Hi, I met trouble when I tried to save some files after revision. One message box popped up and said " Cannot save file,. The file may be in use by another application". Much worse, this file sometimes would be lost when I open this projec next time. It seemed inexplicably disappeared from my folder.

    - 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: openning up the media player 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: openning up the media player 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: openning up the media player 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: openning up the media player Tag: 212506

    - 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. I posted to all the groups that can be concerned by this, if anyone think it's abusive, plz let me know. Tag: openning up the media player Tag: 212492

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.

Can I reuse the following code as it is on a multi-byte platform? #include <string> #include <iostream> using namespace std; void main( ) { string dateDayString ( "07252003FRIDAY" ); size_t indexCh = dateDayString.find_first_not_of ( "0123456789" ); if (indexCh != string::npos ) { string weekDay = dateDayString.substr(indexCh); cout << "WeekDay is " << weekDay.c_str() << "\n" ; } else { cerr << "String is not good.\n" ; } } Tag: openning up the media player Tag: 212298

    - tearoff interfaces Hi. After reading some stuff from Don Box's book "Essential COM" about tearoff interfaces, I am wondering if this is possible from VB. Can a TLB be compiled that would support this, or is this strictly a C++ coding technique? thanks. Tag: openning up the media player Tag: 212289

    - interface substitution Hi. I'm posting this question in this newsgroup in the hope that someone here can help me out. I am currently working on a VB project and find myself needing to do what I am calling interface substitution. Specially, I am wondering if it's possible, in COM, to temporarily substitute a particular interface on an object with the same interface of a different object. I would like to replace the ICollection interface on one of my objects with a "visitor's" ICollection interface and then replace the original interface after I have done some operations on the ICollection. Of course, this all needs to be transparent to the caller. If this is possible, can someone provide some C++ code samples? Also, again, if this is possible, could this technique be used from VB...even if a C++ DLL is doing this for the VB DLL? thanks much. Tag: openning up the media player Tag: 212288

    - precompiled headers causing link errors Hi, we're using precompiled headers in our project. Our object files are put in a library and then linked with a main object to produce the executable. During the library creation we get: warning LNK4006: ___@@_PchSym_@00@UwvevolknvmgUhxsvwfoviPozhgUhlfixvUzurPzhh Olyq@ already defined in ... second definition ignored and then when linking together with the main object we get: error LNK2005: ___@@_PchSym_@00@UwvevolknvmgUtnkEPozhgUhlfixvUtknPCdzbxlme vigOlyq@ already defined in ... We used precompiled headers before and didn't have these problems, until recently we introduced boost. I wander if it has something to do with using templates in precompiled headers... Does anybody have a solution for this problem? Thanks, Bart Tag: openning up the media player Tag: 212280

Try using ShellExecute(Ex) on the media file. If you want to check it
without writing the code, have a look at the ShellExec test
application on www.jddesign.co.uk
