    - dynamic array Hello, (Visual Studio 6.0 - C++ : Console win32 application). Can I declare an array which I don't know it's length on first time, but I want to reference it as an array (not linked table with pre & next). i.e : double myLongArray[1000] ... and suppose somewhere in the code - the size of myLongArray is 1002 - can I change its size on runtime ? Thanks :) Tag: GIF question Tag: 246742

    - MDI system menu issue Hello I have an issue with MDI child windows - they work fine apart from the fact that when there is only one child, and it is maximized, it doesn't get a system menu (i.e. minimize, restore, close) in the top right, and it doesn't get one on the left either. However, when I create another one, they appear. But when I create a third, I get *two* system menus on the right and *two* on the left, one next to the other! Any ideas what's going wrong?

    - Binary Compatibility Question We have an application that was written using VS6. It uses a number of DLL type extensions and we need to write a new extension. We no longer support VS 6 in our development lab and would like to know if a DLL (written in "C") and built in VS.NET 2003 will be compatible with the VS application.

    - dynamic_cast is shite! dynamic_cast doesn't return the correct values: e.g. in my project I have a lot of classes, say A, B, C, D - D being the most derived, A being base - if I put printf(this) in the constructors of them they all get different values, e.g. A will be 0x12fec0, B will be 0x12fec4, C will be 0x12fec8, D will be 0x12fecc, ..etc. I thought this was supposed to happen, but if I have an A* called "pa" (knowing myself that it is also a D*) if I do void test(A* pa) { D* pd = dynamic_cast<D*>(pa); // then d ends up as 0x12fec0, NOT 0x12fecc as I was hoping! } I tried to build a test project to demonstrate but in that all the constructors printed the same values! Help! And yes I have got multiple inheritance, I have also got virtual inheritance. Tag: GIF question Tag: 246698

    - GetFileVersionInfo() I am trying to get various information about the version of a file in order to determine that it is the correct file. I have one working implementation, but I also need to generalize the code a bit in order to use it in a related project. The generalized code works exactly the same way as the non-generalized code with a couple exceptions, but I am running into an error with the GetFileVersionInfo(). Here's a sample: INT Validate(std::string _file, lpData _info) { LPVOID Data; DWORD dwLength; DWORD dwEmpty; dwLength = GetFileVersionInfoSize(_file.c_str(),&dwEmpty); if (!dwLength) return -1; Data = (LPVOID) malloc(dwLength+1); if (!Data) return -2; memset(Data,0,dwLength+1); if (!GetFileVersionInfo(_file.c_str(),NULL,dwLength,&Data)) { free(Data); return -3; } ... } The lpData is a structure containing the information I want to verify about the file. My problem is that the pointer is no longer valid after I call the GetFileVersionInfo(). I checked at run-time by watching the pointers - the 'Data' and '_info' pointers are valid before I call it, but then when it returns (it does not go into the body of the if-block), the values are invalid and cause a crash. E.g. the following: Before After Valid Invalid _info = 0x0012f2b4 --> 0x00050000 Data = 0x00fd7be0 --> 0x0034037c As I said before, I have another version that works just fine. Am I doing something wrong? I pretty much copy-pasted the code. TIA, Tag: GIF question Tag: 246694

    - Reading the system time Hi, Is there a way to read the time so that: 1. If the PC is connected to the Windows Server (NT/2000 or 2003) then read the server time. 2. If the PC is a thin client and connected to the server through the Citrix Server then read the server time. 3. If the PC is NOT connected to the Windows Server (NT/2000 or 2003) then read the local time. Thanks. Regards, Sandford Tag: GIF question Tag: 246677

    - Linking error when using multiple forms and #include<afxinet.h> Hello! I am developping a Visual C++ .NET multiple forms application, which uses FTP connection. When I use more than one form, and include the <afxinet.h> library (necessary for FTP connection), the linker errors occur: error LNK2005: "void * __cdecl operator new(unsigned int)"(??2@YAPAXI@Z) already defined in LIBCMTD.lib(new.obj) error LNK2005: "void __cdecl operator delete(void *)" (??3@YAXPAX@Z) already defined in LIBCMTD.lib(dbgdel.obj) fatal error LNK1169: one or more multiply defined symbols found In order to be clearer, I'll tell the simple steps to create the error: I create a Windows Form C++ .NET application; add a new form (add element->new form); simply include the <afxinet.h> in the Form1. Ok, if you try to run the application, it will. Now, just close the Visual Studio, open everything again, do a NEW compilation, and try to run. (!!!) That's the error! That's why I think it could be a bug of the Visual Studio... Thus, I can just work with FTP connection and only ONE form. We tried the MSDN help, that tells to ignore the library (LIBCMTD.lib), but this causes other link errors. We tried everything we could. If somebody could help me anyway I thank very much.

    - unused template class methods Hi to all, when trying to compile the code below, VC7.1 does it, even if GetSomeSpecialWin32TickCount is unknown. However both GCC and Comeau (in strict mode) give an error. What about compiling unused parst of template classes? We assumed compilers NOT to look inside member function bodies (and in fact VC7.1 does not even detect missing ;) #include <ctime> struct win32 {}; struct other {}; typedef other os_type; template <typename timetraits_t, typename timer_t = typename timetraits_t::value_type> class basic_timer { timer_t start_; timer_t stop_; inline static timer_t now() { return timetraits_t::get_time(os_type()); } public: typedef timer_t value_type; basic_timer() : start_(0) { } value_type start() { return start_ = now(); } value_type stop() { return (stop_ = now())-start_; } }; ////////////////////////////////////////////////////////////////////////// template <typename platform_t> struct clock_traits { typedef size_t value_type; template <typename any_t> inline static value_type get_time(any_t) { time_t t; return std::time(&t); } inline static value_type get_time(win32) { return GetSomeSpecialWin32TickCount(); } }; typedef basic_timer< clock_traits< os_type > > timer_chrono; ////////////////////////////////////////////////////////////////////////// int main() { timer_chrono t; t.start(); t.stop(); return 0; } Tag: GIF question Tag: 246663

    - Need help in Including/converting C files in C++ project Hello, I've a few C files in hand containing functions that can be used to convert a string into MD5 hash string. When I tried to include the c sources and header files to the project, a lot of errors and warnings comes out. The c files can be compiled and run successfully when placed in a standalone project. (with "Project Properties"->"Advanced"->"Compile to" set to "C executables" of course, and compile option "-DMD=5" to specify the MD marco) So I think the sources are Okay. Would anyone please give me a pointer on how to "include the files in C++ project"/"convert these C files to C++ sources"? A second question is: If I included the files, would it be right to just specify the "-DMD=5" in the project properties, or I should specify it elsewhere? Thanks a lot. Regards, Lau Lei Cheong -- If you want to mail to me, please replace all instance of "e" to "a" in my email address. Thank you. Sorry for any inconvience caused, but there's many spam-mailers.

    - switching stdout to a file /* The MSDN Library 10/2001 gives this example for the use of dup()/dup2() to make "stdout" refer to a program-determined file and then restores it NOTE: All error checking deleted for "clarity" Also, the type and arguments of main are not proper either (that's the way it was there) */ #include <io.h> #include <stdlib.h> #include <stdio.h> void main( void ) { int old; FILE *new; old = _dup( 1 ); /* "old" now refers to "stdout" */ /* Note: file handle 1 == "stdout" */ new = fopen( "data", "w" ); /* stdout now refers to file "data" */ _dup2( _fileno( new ), 1 ); puts( "This goes to file 'data'\r\n" ); fclose( new ); /* Restore original stdout */ _dup2( old, 1 ); } /* BUT I'd like to know what's wrong with using this method instead */ void main(void) { FILE *savestdout = stdout; stdout = fopen( "data" , "w" ); ... fclose( stdout ); stdout = savestdout; } TIA Norm Tag: GIF question Tag: 246649

Well i wann to kno the virtual memory layout of the code. and about the assembly cod suppose i hav e a assembly code i wann to convert it into the exe file wann to know how t his can happen. As far as i know the the pointe addres that we mention in t he C++ program are the virtual address like suppose i say int i;int* i_ptr=&i;Here &i returns the virtua address of "i" in the code. But if u compile this program and get th ASM file you can see the registers . I dont think the assembly code i the ASM file specifies the virrtual addr ess. So perhaps for paging th ASM code is converted to EXE file. I am not s ure if this is wha happens. I want to know if it is true. And the stack is not like thi as you have mentioned. [Function 1 Vars] [Stack Pointer] [Func tion Vars] [Stack Pointer] [Function 3 Vars] [Stack Pointer] But as far as know it is like first the invironment varriables are pushed into th stack. then the global values and then the main and other functions Well main is replaced by other functions which are found in th crt0.cpp f ile. And the stack pointers you have mentioned, are the storing the virtual addr ess or the physical address?

    - Can't get VS to convert a dynamic link library to static library. I have a 'C' project that is a Win32 DLL project that I am trying to convert to a static library. I removed the all instances of the DLL on my hard drive to make sure that I was linking with the new static library instead of running with the DLL. I am compiling this library VS.NET 2003. I have changed the VC compiler option under the General tab to Static Library. The project compiles find and builds the .LIB file as expected. No DLL file is generated either, which is also what is expected. I am able to link the .LIB file into my EXE with no errors. However, when I try to run the EXE, I get an error stating that the DLL file for the library that I built cannot be found. I don't understand why the LIB file is still trying to run as a DLL instead of a static library. I have checked and double checked for any errant files that may be linked in, and cannot figure out what is wrong. I have checked the DEF file for any LIBRARY directives. I even checked the RC file for any DLL file references. I can't see any reason why the thing is still behaving like a DLL. Can someone give me any advice on what to do here? -- ----------------------------------- Ken Varn Senior Software Engineer Diebold Inc.

    - Very bad crashes when debugging with Spy++ I have experienced a scenario whereby I experience very bad crashes, when using Spy++. When this crash occurs, not only one program crashes but the whole system hangs - even Ctrl+Alt+Del doesn't do anything. The only thing to do is press the motherboard reset switch. I experience it when debugging while also using Spy++. I tried to reproduce it using a blank "hello world" app rather than my own and it didn't do it, so it must be something about my app, but there are no other symptons of it so it seems strange that it should only affect Spy++, I wondered whether anyone else had seen it nonetheless? Also worthy of note is that this still occurs if my app has only ever had one main thread. Steps taken to reproduce the crash: 1) Start VS.NET, and run windows application under debugger by starting with F5. 2) Start Spy++, and spy on the application's window. 3) Close the application. (Closes without exception and returns to the IDE correctly) 4) Press F5 again (not necessarily having recompiled) to try to start the app again - and crash! The app never starts, the system is from that point on doomed, and will respond to absolutely nothing other than a hardware reset. It doesn't do it if I close down Spy++ between steps (3) and (4) - I can then start it up again and continue spying. My guess is that when spying (as in step (2)), Spy++ has acquired some kind of low-level hook to the application, and when it closed down, managed to get its claws into the IDE because it was its parent process and somehow this has blocked some very low-level function.

    - Load a ICON in a Button hello i've having a bit of a problem with loading a Icon in a Button. Basicaly I got a Dialog resource with a button on it. And with the "property bag" of the button i set it to "Icon" Then I load the icon like so : ( i make sure the button is 16x16) HWND hbut2 = GetDlgItem(IDC_BUTTON2); ::SetWindowPos(hbut2, NULL, 0, 0, 16, 16, SWP_NOMOVE); HICON icon = LoadIcon(_Module.GetResourceInstance(), MAKEINTRESOURCE(IDI_ICON4)); ::SendMessage(hbut2, (UINT)BM_SETIMAGE, (WPARAM)IMAGE_ICON, (LPARAM)icon); Now for some reason, the button loads the Icon 32x32 =/ I made the icon myself and made sure the Icon is 16x16. So is it the LoadIcon API that loads the icon as 32x32 or is it the Button that cannot accept icons smaller then 32x32 ? ok thanks for you input =] Tag: GIF question Tag: 246528

    - issue with the new VC .NET #import for smart pointers OK. this is my second issue with the new VC .NET #import for smart pointers. for the following declaration in an ODL dispinterface IFoo { methods: [id(1)] IDispatch* GetFoo2(); } dispinterface IFoo2 { } I get in VC 6 these wrappers: _COM_SMARTPTR_TYPEDEF(IFoo, __uuidof(IDispatch)); _COM_SMARTPTR_TYPEDEF(IFoo2, __uuidof(IDispatch)); in VC 7 I get _COM_SMARTPTR_TYPEDEF(IFoo, __uuidof(IFoo)); _COM_SMARTPTR_TYPEDEF(IFoo2, __uuidof(IFoo2)); The problem is that I am having difficulting utilizing the generated wrappers because IFoo2 is not returned what is returned is IDispatch. I know I can access these without the wrappers but that just seems stupid. Probably I need to make a minor modifications on how I use the smart pointer but I am at a loss for what that would be.

    - COM - Should interfaces be marshalled when passing between threads Hi, My understanding is that you dont need to marshal interface pointers between threads of a process when they are all in a Multi Threaded Apartment (all threads in the process call CoInitializeEx(NULL, COINIT_MULTITHREADED)). I am getting apparently conflicting advice from some pages - here are a couple of snippets: 1) From "http://msdn.microsoft.com/msdnmag/issues/1100/wicked/" Passing a raw interface pointer (a 32-bit address in memory) to another thread without marshaling it bypasses COM's concurrency mechanism, and can produce all sorts of undesirable behavior if the sending and receiving threads reside in different apartments. (In Windows® 2000, because two objects can share an apartment but reside in different contexts, it can even get you in trouble if the threads are in the same apartment.) 2) From "http://support.microsoft.com/?kbid=150777" Multi-threaded Apartment model (MTA): ... Interfaces are not marshaled between threads. Thanks for this and past help, David. Tag: GIF question Tag: 246487

    - vtable help needed for RTTI solution Hello I have made the following code to give me custom run-time type information because the standard RTTI doesn't give me what I want, i.e. it doesn't seem to be able to compare two objects and give a definitive boolean, yes or no answer as to whether the first either is, or is derived from, the second (but not the other way round, i.e. fn(D*,B*) must return true; but fn(B*, D*) false.) (I can't think how this is possible using standard RTTI - if it is please demonstrate a replacement for my _tmain function that accomplishes the same thing...) I'm quite happy with the code, as it seems to work in the way that I want, *but* it does involve a bit of work in two places and it's largely the second of these I'm looking for the sort of trickery I know only you experts are capable of... you might find it easier to compile it first to see what it does, then read it, rather than the other way round... 1) I need to explicitly specify getsingleid for every class that I want to derive from IRegable (I'm not too fussed about this, as I've got used to the idea of including a special header file containing a list of the instantiations at the bottom of the template's cpp file) 2) I need to override getid(bool) for *every* class that I want to derive from IRegable - implementing it isn't *too* time consuming in its logic - as for each class I implement it for, I only have to look at the classes it directly implements aswell as its own name to write its implementation, but my main worry is forgetting to implement it at all - if I derive a class B from IRegable (and implement getid(bool)) but then derive a class D from B and forget to implement getid(bool), the compiler doesn't complain, and D falls back on B's implementation of getid, giving it the wrong ID, obviously therefore causing fn(B,D) to give a false positive. This bothers me - and I was wondering if it was in some way possible to 'hack into the vtable' in order to accomplish this more elegantly (or not, as the case may be!) I'm really looking for, well, basically some magic way of not having to remember implement getid for every class. But my gut instinct tells me it's possible... is it? If it's not, please tell me! (p.s., it is necessary to have the multiple inheritance and the 'virtual public' thing) (p.p.s., in the real app, '32' might be replaced by something larger depending on how many classes there are.) #include <bitset> #include <string> using namespace std; static int nextid = 0; template<class T> bitset<32> getsingleid() { static bitset<32> retval; if(retval.none()) retval.set(nextid++); return retval; } class IRegable { public: virtual bitset<32> getid(bool bComposite) const = 0; virtual string getname() = 0; static void fn(IRegable* obj1, IRegable* obj2) { if(((obj1->getid(true)) & (obj2->getid(false))).any()) _tprintf(_T(" ... is a %s\n"), (obj2->getname()).data()); else _tprintf(_T(" ... is not a %s\n"), (obj2->getname()).data()); }; ~IRegable() {_tprintf(_T("IRegable object \"%p\" is dying!\n"), (void*)this);} }; class ChildWindow : virtual public IRegable { public: virtual bitset<32> getid(bool bComposite) const {return getsingleid<ChildWindow>();} virtual string getname() {return string(_T("ChildWindow"));} }; class Window : virtual public IRegable { public: virtual bitset<32> getid(bool bComposite) const {return getsingleid<Window>();} virtual string getname() {return string(_T("Window"));} }; class WndProcWindow : public Window { public: virtual bitset<32> getid(bool bComposite) const { return bComposite ? getsingleid<WndProcWindow>() | Window::getid(true) : getsingleid<WndProcWindow>(); } virtual string getname() {return string(_T("WndProcWindow"));} }; class SimpleControl : public ChildWindow { public: virtual bitset<32> getid(bool bComposite) const { return bComposite ? getsingleid<SimpleControl>() | ChildWindow::getid(true) : getsingleid<SimpleControl>(); } virtual string getname() {return string(_T("SimpleControl"));} }; class ComplexControl : public ChildWindow, public Window { public: virtual bitset<32> getid(bool bComposite) const { return bComposite ? getsingleid<ComplexControl>() | ChildWindow::getid(true) | Window::getid(true) : getsingleid<ComplexControl>(); } virtual string getname() {return string(_T("ComplexControl"));} }; int _tmain(int argc, _TCHAR* argv[]) { { ChildWindow child; Window win; WndProcWindow wndproc; SimpleControl simple; ComplexControl complex; IRegable* objs[] = {&child, &win, &wndproc, &simple, &complex}; for(int i = 0; i < 5; i++) { _tprintf(_T("Object of type %s:\nSimple ID : %s\nComplex ID: %s\nAddress: 0x%p\n"), objs[i]->getname().data(), (objs[i]->getid(false).template to_string<char,char_traits<char>,allocator<char> >()).data(), (objs[i]->getid(true).template to_string<char,char_traits<char>,allocator<char> >()).data(), (void*)(objs[i])); for(int j = 0; j < 5; j++) IRegable::fn(objs[i], objs[j]); } } } Tag: GIF question Tag: 246480

hey all,

i use ImageSource (www.smalleranimals.com) so i can read, and resize JPG's
in my app, which i would recommend 100% for anyone looking for the same.

but they do not work with GIF format, i believe because of the whole patent
issue. what i am looking for then, is a library i can use that reads GIF
files. all i need to do is open GIF files. heck, if i can open them into
RGB format, then i can still use ImageSource to do the rest, resize, add
transparencies etc.

so if anyone knows of a decent library, please let me know.

thanks!
