    - C4744 - 'var' has different type in 'file1' and 'file2' I'm getting warning C4744 from the linker when building with LTCG. The following sample reproduces it: --------------------------- // Header.h #include <xmmintrin.h> class Vector; extern const Vector ZeroVector; class Vector { public: Vector( float x_, float y_, float z_, float w_ ) : x(x_), y(y_), z(z_), w(w_) {} union { struct { float x, y, z, w; }; __m128 q; }; }; --------------------------- // Source1.cpp #include "Header.h" const Vector ZeroVector( 0.0f, 0.0f, 0.0f, 0.0f ); --------------------------- // Source2.cpp #include "Header.h" #include <stdio.h> void main() { printf( "%f\n", ZeroVector.x ); } --------------------------- Is the warning erroneous? The compiler only emits it in LTCG builds - but could it cause bad code generation in other configs? What's the correct workaround here, the warning seems to go away only if I tag the declaration of ZeroVector with __declspec( align(16) ). Should it be necessary in this case though? -- Andy Tag: go to a definition Tag: 284285

    - Beginner GUI question I am writing a program in C++ and I want to add a GUI. This program will be more of an application and the GUI will probably get fairly complex. I am using Microsoft Visual C++, version 6.0 (very old). I would just as soon do it visually in the resource editor. I build a dialogue window and MSVC++ creates a .rct file. But now how do I call/instantiate this from my program? The basic call appears to be DialogBox(hInstance, MAKEINTRESOURCE(IDD_DIALOG1), NULL, DialogueProcess) where IDD_DIALOG1 is the name I gave it in the resource builder (original, huh?). When I try to compile though, IDD_DIALOG1 is undefined. Do I need to make a header file or .rc file by hand or something? Do I reference the dialogue in a different way? Is it a setting in the IDE somewhere? Am I going about this in altogether the wrong way? *** <a little off topic> Just for the sake of my pride if nothing else ... I'm not really a beginner, I've programmed in C, C++ and Java for years and written dozens of GUI applications in Java Swing. I googled for basic tutorials on Windows GUI programming and found a pretty good one (http://www.winprog.org/tutorial/) but the author dealt with this part by hand-editing a .rc and resources.h file himself ... there aren't really any docs on how he did this though. -- Joe Cosby http://joecosby.com/ Magister Mundi sum! :: Currently listening to Cello Concerto No.1 in C Major Moderato, 1768, by Haydn, from "Cello Concertos" Tag: go to a definition Tag: 284275

    - Thanks to Igor Tandetnik and Victor Bazarov Hi, I had a question about a week ago and you both responded. I got sidetracked, but when I got back to it, both your responses were EXTREMELY helpful. I am sorry it too so long to get back to you, but I wanted to make sure you knew that your help was appreciated and saved me a lot of searching for the answer.

    - Please help for C question! Hello fellows, I ran again in a little snag concerning questions. As you may already know from my previous posts, I am using a CCS compiler to compile my C code for a Microchip! So my problem might be compiler specific. But I don't think so. So I will ask this question in this news groups since I am not sure about the code myself. I am simply passing a pointer that points to an array of structures stored on the heap(or in my case in upper Ram of the microchip) In any case, C is C! I don't seem to be able to assign any values to my items of my structures. Please view code below and breif explaination of problem! Here is the code: ======================================ACM152.c #include <LCD.c> //LCD FUNCTIONS void main() {LCD_PAINTSCREEN(1);} ============================================ =========================================LCD.c #include <TCP.c> //TEXT CODE PAGE void LCD_PAINTSCREEN ( int FLASHSOURCE) { struct MCB* pMCB; pMCB = malloc(16*sizeof(struct MCB)); LCD_GETMSG_MCB(pMCB); free(pMCB); } ============================================ =========================================TCP.c struct MCB{ int ENDOFCHAR; //:TRUE:=End of char / :FALSE:=Valid char int A0; //LSB OF MESSAGE ADDRESS IN PAR FLASH int A1; //MIDSB OF MESSAGE ADDRESS IN PAR FLASH int A2; //MSB OF MESSAGE ADDRESS IN PAR FLASH int LEADING_PIX; //LEADING SPACES, BEFORE CHARACTER int TRAILLIG_PIX; //TRAILLING SPACES, AFTER CHARACTER int CHARSPACING; //SPACES BETWEEN CHARACTERS int CHAR_TRSP; //CHARACTER TRANSPARENCY int mCHAR_BCOLOR; //MSB OF BACK COLOR int lCHAR_BCOLOR; //LSB OF BACK COLOR int mTEXT_COLOR; //MSB OF TEXT COLOR int lTEXT_COLOR; //LSB OF TEXT COLOR }; void LCD_GETMSG_MCB( struct MCB* pMCB) { pMCB[0].ENDOFCHAR = 1; //"1" does not get assigned to the item?? } ================================================== The program compiles without errors! But for some reason, I am not able to assign the value of "1" to the ENDOFCHAR item of the MCB, please see this in the TCP.c file above. Can someone please help ! All feedback appreciated. -- Best regards Robert Tag: go to a definition Tag: 284258

    - Calling VC++ dll in exe (VC++) Hi everyone, I'm trying to call a DLL that I created using Microsoft Visual C++ 6.0 in an win32 Console Application.The DLL contains the function(Getarray) I'd like to call in the win32 Console Application.I put the DLL into C:\windows\system32. As I got the error message: error C2065: 'Getarray' : undeclared identifier.... I put the DLL into the directory where the executable for the win32 Console application was to be created.But I still have the same error message.By creating the DLL I included in the project a .def file in order to export the DLL.I also specified the .lib file under Project Settings->Link->Object/Library- Module and I can't understand why the function can't be found.....

    - Unsigned long long typedef Hello, Can somebody explain why the compiler fails to compile the following C++ code : typedef long long bigint; int test() { unsigned bigint ullVar(0); } error C2146: syntax error : missing ';' before identifier 'ullVar' error C3861: 'ullVar': identifier not found Excerpt from the Microsoft Visual Studio 2005 Documentation: typedef declarations do not introduce new types â?? they introduce new names for existing types. No problems when I use unsigned in the typedef: typedef unsigned long long ubigint; int test() { ubigint ullVar(0); } So I wonder, is this a bug in the compiler?

    - Two function prototypes in two separate .h files Hi, I am beginner to C++ but not to C, though I worked on C some 15 years ago. So I need some help. I was implementing a call to EnumEnhMetaFile () function as per the docs on MSDN. Its prototype is: EnumEnhMetaFile (HDC hdc, ..., CONST RECT * lpRect); I have given only those args that are problematic. Before calling this function, I coded as given below, taking a cue from an example on MSDN. HDC hDc; hDC = GetDC (hWnd); RECT * lpRect; GetClientRect (hWnd, lpRect); bOK = EnumEnhMetaFile (hDc, ..., lpRect); I get compilation errors as follows: 1. On GetDC, it says no args allowed. Also GetDC returns a "CDC *" and not of HDC. 2. On GetClientRect, it says it takes only one arg. If I use "GetClientRect (lpRect)", it compiles but crashes on running. When I try to go to definitions, they point to the prototypes in "afxwin.h" and not to that in "winuser.h". My queries are: 1. How can I force the prototype in winuser.h rather than that in afxwin.h? 2. If that is not desirable or not possible, can I cast "CDC *" to "HDC" so that my code will be as: CDC * pDc; pDC = GetDC ( ); RECT * lpRect = 0; bOK = EnumEnhMetaFile (pDc, ..., lpRect); 3. Which is the forum for discussing GDI issues? ThanQ... Tag: go to a definition Tag: 284224

    - typename and sizeof Hi to all, quite surprisingly, we discovered that inside 'sizeof', the keyword 'typename' is not required. apparently, sizeof does not care if -say- A<T>::type is a type(def) or a static member. for example, this compiles in Comeau compiler online: template <class T> struct A { typedef char type;}; template <class T> struct B { static const int N = sizeof(A<T>::type); // note 'typename' missing here }; int main() { return B<int>::N; } while it obviously gives error if we try to declare a member in B, whose type is A<T>::type (without 'typename'). it still compiles if I add a partial specialization where 'type' is not a type template <> struct A<int> { static const int type = -99; }; Is this fact documented in the standard? I think it's not explicitly mentioned in "C++ Templates - The Complete Guide" by Vandevoorde/Josuttis. Tag: go to a definition Tag: 284129

    - Passing an already declarted array of structures! Hello, Another tip on structures would greatly be appreciated! Consider the following: ==================================================== struct S { int x; int y; }y[]={1,2,3,4}; //Now array of this structure is declared at the same time the structure is declared! //Declare a function that is supposed to take a pointer to the array of sturctures! void f(S* p, int size) { for (int i = 0; i < size; ++i) { DoSomething(p[i].x); } } //Calling function f(y, 100); ======================================== I am trying to pass the already declared array of structures to the f function by the code shown above! I get the following error! "Identifier is already used in this scope" I know if I declare the array of structures seperately it works, but suppose one wants to declare everyting at once as done above, how would he go about it?

    - Template Code compile errors Hi All, I have obtained some heavily templated open-source code, and using VS8 it will not compile. The errors I am getting don't make sense, for example - cell.hh(110) : error C2244: 'olb::Cell<T,Lattice>::iniEquilibrium' : unable to match function definition to an existing declaration 1> cell.h(129) : see declaration of 'olb::Cell<T,Lattice>::iniEquilibrium' 1> definition 1> 'void olb::Cell<T,Lattice>::iniEquilibrium(T,const T [Lattice<T>::d])' 1> existing declarations 1> 'void olb::Cell<T,Lattice>::iniEquilibrium(T,const T [Lattice<T>::d])' This is a very typical error report, most of them are indeed C2244 ... The part which doesn't make sense to me is that the 'definition' seems to exactly match the 'declaration' ... what gives ? Not being a c++ expert by any means, I am at a loss - even for something to try. Any constructive comments would be much appreciated ! Sincerely, -- gordon Tag: go to a definition Tag: 284097

    - C4244 I'm implement ISerializeStream on top of another stream library. ISerializeStream gives lengths as ULONGLONG while the other library uses size_t. I write correct code to ensure that data larger than the largest size_t gets broken into multiple reads. However, even after ensuring that the ULONGLONG value is appropriate, I can't put it into the size_t without getting C4244. What's the proper way to avoid this message in proper code like this?

    - VS 2005/C++/x64 Hi... We're taking a pile of our old C++ and C# projects over to an x64 environment and we're running into some oddities. I've found some article referencing some of the pitfalls but also some things that just aren't lining up. We've added the x64 platform configuration to the solution and that's what we're trying to build with. 1) our C++ projects are using pre-compiled headers, but if we build 32-bit first then x64 we don't get a full list of compatibility problems. Uncheck pre-compiled headers and it explodes. Are pre-compiled headers just not supposed to be used for cross-platform builds? 2) I found articles saying int and long are still 16 and 32-bits respectively even with an x64 bit while size_t, time_t and others supposedly become 64-bit (major source of compiler warnings) *but* 2a) when I mouse over a size_t declaration in my code in VS, it says "typedef unsigned int size_t;" Shouldn't that be unsigned __int64? Of course you can't find which include file's typedef is being used easily. Is the intellisense just wrong? 2b) when I went searching the VC++ includes for size_t declarations I found that time.h has #if !defined (_WIN32) #error ERROR: Only Win32 target supported #endif but then lower down has #ifndef _SIZE_T_DEFINED #ifdef _WIN64 typedef unsigned __int64 size_t; #else typedef _W64 unsigned int size_t; #endif #define _SIZE_T_DEFINED #endif and *still* lower down has #ifndef _SIZE_T_DEFINED typedef unsigned int size_t; #define _SIZE_T_DEFINED #endif Especially since time.h includes crtdefs.h at the top, it doesn't look like the size_t defs in time.h are active, but it does look a bit messed up. There are also 64-bit definitions for time_t in the file but the stuff at the top makes it look like it would blow up. Any tips? Thanks Mark Tag: go to a definition Tag: 284053

    - Simple to use hash function? I want to hash a users password in the client and send the hashed value over the wire and store the hashed value on the server, the server never needs to know the real password. I'm looking for a simple to use hash function for VC++ .net 2003 and can't find one. In MSDN I was looking at CryptCreateHash but for some reason in the sample code you have to call CryptAcquireContext first and check for success, etc... I want something simple like: std::string Hash = CreateHash( Password ); I know I can wrap CryptCreateHash in a function or class do this, but I was wondering if there is something simpler I can use. If not I'll go ahead and wrap it and test it and such. Tag: go to a definition Tag: 284021

    - Pointer refering to an array of structutes? Hello, I would like to create an array of structures and then be able to access any item of the structure in any element of the array via a pointer. This way if I am in a function and I need information of an item of a particular structure, I can simply just pass the pointer to the structure and not the whole array of structures! So I believe I need to create a pointer that can reference an array of structures. Right? here is my structure I declared: struct MAB { int FONT_NAME; //NAME OF FONT int LETTER_HEIGHT; //HEIGHT OF THE LETTER int LETTER_WIDHT; //WIDTH OF THE LETTER }; I then declared the array of structures: struct MAB ARY[20]; Then I tried to create the pointer to this array: struct MAB (*mypointer)[20]; I get errors... this is how I saw some examples done on the Internet! Can anyone *please* help me. Sincerely Rob -- Best regards Robert Tag: go to a definition Tag: 283987

    - about unary_function Hello everyone, I am wondering what is the practical usage of unary_function? Could anyone list some practical benefits? My question is, a class like class Foo : public std::unary_function<class A, class B> is always the same (could use similar implementation) to template <class A, class B> class Foo So we could always use the alternative approach to replace unary_function. thanks in advance, George Tag: go to a definition Tag: 283985

Many times in VC++ 6.0, I will try to go to a definition, and it pops
up a MessageBox saying:

---------------------------
Microsoft Visual C++
---------------------------
The symbol 'MyFunction' is undefined.
---------------------------
OK
---------------------------

Anyone know how to fix this?

Ensure that the header & source files containing that symbol are
included in the list of files in the project.

If that's not the issue, try closing the workspace and deleting the
.ncb file. It'll get recreated when you re-open the workspace. That
often fixes such issues.

I often wonder why the IDE doesn't just erase this file periodically anyway
since it has to be done so often... I know that might make it a little
slower starting the IDE, but it would save a ton of people from spending a
lot of time wondering why Intellisense isn't working.

Yes. Install VisualAssist or upgrade VC++. VC++6.0 has
notoriously fragile and weak intellisence mechanism (in
comparison to modern ones).
