- Migration from VC++ 6.0 to VC++8.0 I have a product developed in VC++6.0, and now we are using the VS2003 IDE and the libraries all are from MFC42.dll s only, and now I want to migrate my code to VC++8.0, what steps I need to take, and what changed I have to make. The existing application is having Dlls, COM Dlls, AciveX controls, and some Static Libraries and IDE s developed in MFC. please provide some suggestions.

- Error when trying to add method to ActiveX control Hi there, I get an error when I try to add a new method to my ActiveX control. I try to add the method to the dispinterface using the wizard, in the same way as I have done it 50 times before without problems. When I hit ¡®Finish¡¯, the following error occurs: Failed to return new Code Element. Possibly syntax error. New Element Name: NameOfMyMethod After which the class of the control disappears from the class view. I¡¯ve tried several things now, including deleting any ncb files, rebuilding the entire solution and re-installing Visual Studio. Without much luck. I¡¯m hoping someone has an idea what may be going on here... Thanks, Peter Tag: Visual C++ General Using Hyperlinks as text in a Tree-View control Visual C++

- Debug Assertion Failed - and no idea why Are you passing a CWnd type pointer to this thread in argument What are the operations you are trying to perform on that pointer The correct way of using the window in new thread would be to 'by it's HWND', you can create a CWnd object and attach the HWND to it for simplicity, but avoid using MFC windows class pointers in newly created thread (or the thread who didnt create that window).

- memory leak debugging : Why are the memory allocation numbers different? Hello. I'm trying to debug some case where there are some memory leak. I tried _CrtDumpMemoryLeaks() to see where memory leaks. For example, it display that there are some leaks at test.cpp(24) :{142} and test.cpp(28) :{143}. However the memory allocation number between {, and } are different when you see in the debugger's output window and when you set these : _CrtSetReportMode ( _CRT_WARN , _CRTDBG_MODE_FILE ); _CrtSetReportFile ( _CRT_WARN , _CRTDBG_FILE_STDERR ); When you set it to report to stderr, you don't need to invoke your program in debug mode. You can just start it from the prompt. However, the allocation numbers are different compared to the ones in the debugger's ouptut window. The reason I don't want to use debugger this time is that it takes long time to see the problem, and it is very process and memory intensive program. So, if I just let the program run and figure out where the problem happens, it would be more convenient. ( To crash the program, it takes about 5~6 days. ) So, can anyone tell me why the allocation numbers are different and how to translate the one from the stdout the ones in the output window, if possible Thank you.

- ML.EXE warning A5006: No more support for .MODEL FLAT, SYSCALL? Or, another option (I just discovered) that seems to work: .686 .MODEL FLAT, C .CODE OPTION LANGUAGE: SYSCALL abs EQU abs@Sunfish@@YANN@Z abs PROC x: REAL8 fld x fabs ret abs ENDP END In other words, use .MODEL FLAT, C but then specify OPTION LANGUAGE: SYSCALL. Alternatively, the following also seems to work: .686 .MODEL FLAT, C .CODE abs EQU < abs@Sunfish@@YANN@Z > abs PROC SYSCALL x: REAL8 fld x fabs ret abs ENDP END That is, put the SYSCALL in the PROC. Either way, the warning message goes away and everything links and runs properly (and with the desired _cdecl calling conventions).

- std::vector slow Hello I wrote a simple template class Vec and when I compile with optimization under Visual Studio 2005, std::vector takes almost twice as long. I would have thought that std::vector is much more optimized than anything I could roll myself. Am I mis-using std::vector somehow Or is it really that inefficient What I did is basically 2^10 loops of allocating a vector<int> of size 2^16, filling it, and finding the largest element. Here is the code: // VecTest.cpp : Defines the entry point for the console application. // #include <stdio.h> #include <stdlib.h> #include <time.h> #include <vector> template <class T> class Vec { public: Vec(void) { mPtr = NULL; mNElem = 0; } Vec(int size) : mNElem(0), mPtr(NULL) { if (size < 0) throw "Size < 0\n"; if (size > 0) { mPtr = new T [size]; if (mPtr == NULL)throw "Vec allocation failed\n"; mNElem = size; } } ~Vec(void) { if (mPtr) delete [] mPtr; mPtr = NULL; mNElem = 0; } int size(void) const { return mNElem; } T &operator[](const int i) const { return mPtr ;} private: T *mPtr; int mNElem; }; using std::vector; const static int n = 2<<16; const static int times = 2<<10; int main(int argc, char* argv[]) { double s; clock_t start, end; vector<int> y(n); Vec<int> x(n); start = clock(); for (int j=0; j<times; j++) { s = 0; for (int i=0; i<n; i++) { y = i; } for (int i=0; i<n; i++) { if (y >s) s=y ; } } end = clock(); printf("%-20s: %g\n", "std::vector Time", (end-start)/(double)CLOCKS_PER_SEC); start = clock(); for (int j=0; j<times; j++) { s = 0; for (int i=0; i<n; i++) { x = i; } for (int i=0; i<n; i++) { if (x >s) s=x ; } } end = clock(); printf("%-20s: %g\n", "Vec Time", (end-start)/(double)CLOCKS_PER_SEC); printf("Press Enter to continue\n"); getchar(); return 0; } Here are my compiler options: /O2 /GL /D "WIN32" /D "NDEBUG" /D "_CONSOLE" /D "_UNICODE" /D "UNICODE" /FD /EHsc /MD /Fo"Release\\" /Fd"Release\vc80.pdb" /W3 / nologo /c /Wp64 /Zi /TP /errorReport rompt Here are my linker options: /OUT:"C:\Documents and Settings\dklein\My Documents\Visual Studio 2005\Projects\VecTest\Release\VecTest.exe" /INCREMENTAL:NO /NOLOGO / MANIFEST /MANIFESTFILE:"Release\VecTest.exe.intermediate.manifest" / DEBUG /PDB:"c:\documents and settings\dklein\my documents\visual studio 2005\projects\vectest\release\VecTest.pdb" /SUBSYSTEM:CONSOLE / OPT:REF /OPT:ICF /LTCG /MACHINE:X86 /ERRORREPORT ROMPT kernel32.lib user32.lib gdi32.lib winspool.lib comdlg32.lib advapi32.lib shell32.lib ole32.lib oleaut32.lib uuid.lib odbc32.lib odbccp32.lib Here is some version info: Microsoft Visual Studio 2005 Version 8.0.50727.762 (SP.050727-7600) Microsoft .NET Framework Version 2.0.50727 Microsoft Visual C++ 2005 77626-009-0000007-41350 Microsoft Visual C++ 2005 Microsoft Visual Studio 2005 Professional Edition - ENU Service Pack 1 (KB926601) This service pack is for Microsoft Visual Studio 2005 Professional Edition - ENU.

- Reg: PRJ0050 error Hello all, Firstly, I've started programming in MFC just a few days back, so please excuse me if I sound too naive. I'm just a beginner... I've written a MFC DLL for implementing a Deskband Object. I used the Band Sample, thats available on MSDN. Since the band sample was using CreateWindow() to create all child windows, including buttons etc.. I felt I needed something more. I was of the idea of using MFC (or wxWidgets, which is what I prefer). Anyway, the MFC DLL is giving me the PRJ0050 error. I am the administrator & I have implemented the DllRegisterServer Method. I've also specified it in the .def file of the project. But, I continue to face the same error. I tried to manually register the DLL, but it says that the the specified library cannot be found, which to the best of my rather limited knowledge, implies that it is unable to locate the DllRegisterServer Method. I'm using MFC as a shared DLL. Please help.. Any help or pointers will be appreciated. Regards, Vikhyat. Tag: Visual C++ General Using Hyperlinks as text in a Tree-View control Visual C++

- Member offsets in derived classes Ramkrishna Pawar wrote: IMO apart from the vptr being the first 4 bytes, you can't be sure of other member's position, it's compiler dependant. I am quite nearly positive that a major purpose of structures originally were for storage to/from external media. Yes, I understand that the position is not guaranteed but we are talking about VC. So as far as VC is concerned, is there anything other than packing and the vtable that affects position All other compilers other than VC are irrelevant for this.

- GDI+ Image object You cannot simply move the initialization sequence to the global scope, outside a function. But you can try something like this: Code Snippet static Gdiplus::GdiplusStartupInput gdiplusStartupInput; static ULONG_PTR gdiplusToken; static void InitGdiPlus() { GdiplusStartup(&gdiplusToken, &gdiplusStartupInput, NULL); // TODO: process errors } static bool unused = (InitGdiPlus(), false); Gdiplus::Image image(L"c:image.bmp"); . . . Now you should be sure the unused variable is initialized at run-time before your images. Hopefully this is guaranteed by the compiler.

- FYI, internal compiler error with template code + resolution This post is for any who are searching for a fix for their ICE in a similar situation. Using Visual C++ 6.0 // The second provides support for statements such as // if (*iterator == 0) T* operator*() { ...... This was part of a nested template class in a .h file.(class iterator inside another template class) The "operator" line generated an ICE. The fix was totally accidental. All I did was move the entire project directory to a new drive. (Different drive letter and different physical drive.) I told VC to open the old workspace so it would purge from the recent file list. When I re-opened the workspace from the new location and hit F7, the error was gone. I'm sorry I can't replicate the exact error message but I was surprised at its disappearance. This is not the best fix, and I've had ICE's in many different projects with this kind of template code (VC doesn't like template code) *shrug* Perhaps moving to a different path on the same drive would work too, I don't know.

- How to pass variable from one dialog box to other Hi, I would suggest you to use an immutable class to hold the parameters you are passing from a Diablog box A to B. You need to have pointer to B in A. And a method Accept(ParamsFromA* params) in your class B. Then you will need just to collect your parameters in class A and call instanceOfB->Accept(ParamsFromA* params). For the question regarding TCP/IP. It's better to put the code in a Utilities package since it can be classified in a technical domain and should be independant of your application domain and workflow domain. You can find more information about this by googling 'Layered architecture pattern' Best regards, Tag: Visual C++ General Using Hyperlinks as text in a Tree-View control Visual C++

- C# and C++/CLI sharing objects Hi guys, I really need some help on this as i'm going slowly insane. What I have is a windows service written in C++/CLI exposing an object with TCP remoting. The remoted object loads a bunch of other objects from a database into a List<> and keeps them in memory for the lifetime of the service. I have another project which is a C# Winforms application which accesses the service using TCP remoting and wants to get access to an object in the list. However, when my C# project gets the object it seems to get a copy of it rather than a reference to it. All the parameters look the same but if I attempt to update it, the C++/CLI "copy" of it doesn't change. I have an event in the object which fires when a property of the object is changed. I want to consume this event in the C# project. Now if I change the C# copy of the object the event gets fired and my C# delegate gets called. However, if I pass an ID and get the C++/CLI code to find the object matching the ID it updates the object but the event is not fired. I hope this makes sense. Does it sound possible, what i'm trying to do Or maybe i'm just missing something obvious. Any help would be greatly appreciated.

- Defines for specific windows versions I don't understand the relevance of the MOF class; if it relevant, then your question requires clarification. If it is not relevant, then the MOF class is irrelevant. A #define gets evaluated by the preprocessor and does not exist after the preprocessor, therefore it is useless during execution.

For those LNK2005 errors, does your project linking to some other libraries If yes, then most likely that these libraries link with libc.lib or other statically linked CRT libraries, which cause redefinitions because your project is linking with a different(newer) version of CRT library. In this case, if you own these libraries, rebuild them in VC2005, if not, ask the library publisher to send a new version of their library which is build with VC2005. 3. If all above does not help, change project settings "Show Progress" to "Display some progress messages" in the General property page of the Linker folder in a project's Property Pages dialog box, rebuild your project and show us the result in output window. hope it helps rico Tag: Visual C++ General Using Hyperlinks as text in a Tree-View control Visual C++

Re: Visual C++ General Using Hyperlinks as text in a Tree-View control
kirants
What do you mean by hyperlinks Just for looks , or are you asking about the hyperlink type of action on clicking too
If so, no there is no such support with the tree-view common control. If you need it, you have to handle the tree view notifications in the parent window and do the necessary ( e.g. ShellExecute )

If you set the Track Select property of tree control to True (in Dialog Editor), or apply programmatically the TVS_TRACKSELECT style, then tree items will look like hyperlinks when you move the mouse over.
