• LiamD VS .Net 2005, how to disable intellisense...

  Hi I am really frustrated with the performance of VS .Net 2005. This is because I always see at the bottom "updating intellisense..." and it uses 60% to 70% of CPU. How to disable this updating of intellisense... Please this is making Visual studio unusable. Thanks Chandra My guess is that Intellisense performance is killed by some of the following: excessive use of templates in code, #import for large native COM classes (biggie IMO), errors in parsing which cause loops (i.e. it never completes), corruptions in NCB files (deleting usually makes things better for a while),  preprocessor code greying, very large precompiled headers, slow update of class view pane.     I h ...Show All

• John Sobernheim MFC Question

  (I cannot find a MFC forum here so I thought this would be the best place to post) I'm writing a program in C++ using VS.NET 2005 with the DOC/VIEW approach. I ran the wizard to generate the MFC project and I have the following .h files: MainFrm.h Resource.h Sketch.h SketchDoc.h SketchView.h stdafx.h I have the following .cpp files: MainFrm.cpp Sketch.cpp SketchDoc.cpp SketchView.cpp stdafx.cpp I have a very simple question - how I do I change the name of the window that appears I thought you go into the initInstance in Sketch.cpp and right before it shows the window, you invoke the SetWindowTitle method, but that doesn't exist on the m_pMainWnd variable, which appears to be CWnd. I hav ...Show All

• Ji Zhang &amp;#91;MSFT&amp;#93; Option Explicit & Option Strict

  I have read a few topics about Option Explicit & Strict. I'm curious if either of these are available for C++. And if they are, would it notify me if I have not returned a pointer to memory. i.e.: delete pHeap; Thanks! - np Option Explicit and Option Strict are a VB/VB.NET thing only. You can consider them to be both On for C++ and there is no way to turn them off in C++. Also I'm not sure what this has to do with pointers and freeing memory. VB does not have pointers and it also does not need something like delete because it uses a garbage collector. I guess the reason I was asking is because, I was hoping there was a way to catch wether or ...Show All

• bryndabella how can i turn off the "/gs" flag ?

  i hope im in the right forum.. im using MSVC++6 and i want to turn off the /GS flag, how can i do this thanks ! im so sure that VC6 is not support this option.. where did i need to write it in my program i mean after the "include..." and before the "int main()" or where and what is the syntax thanks ! Umh, I'm certain you know that already, but obviously /GS or /GS- are command line options that are passed to the compiler driver (cl.exe) on the command line. You can always look these up in the index of MSDN Library to find the corresponding setting in the IDE. So, it is nothing you would do in the source code. Are you sure you mean /GS (and not /Gs) There's probably a corresponding pr ...Show All

• JohnnyR c2228 and another question

  hi, i have a bunch of c2228 errors in my code now that states left of '.RXbyte' must have class/struct/union the part of code it points to is as follows: m_bSendECG = false ; m_cRS232.TXbyte(0x00); m_cRS232.RXbyte(&Byte); m_cRS232.TXbyte(0x12); m_cRS232.RXbyte(&Byte); m_cRS232.Clear(); m_iBufferPos = 0; im not sure how to fix it. im sure its obvious by now that i didnt write most of this code. im a noob and most of this code is way over my head. im trying to understand it as i correct it. its part of a big project with many files inter-linked with one another. i apologize if my questions are very basic and i hope you will bear with me. thanks in advance. ...Show All

• lufa Question about VSC++2003 to VSC++2005 conversion.

  I'm just starting with Visual Studio 2005. I have some tutorials that are written for VS2003. Most of the programming differences I've figured out but I am having trouble with this one: VS2003 String *myContainer = 0; Ive tried String ^myContainer = 0; but I get a compiler error error C2440: 'initializing' : cannot convert from 'int' to 'System::String ^'. The 0 pointer conversion would be ambigious with automatic boxing for handles. Hence, VC reuses the nullptr proposal. The nullptr keyword converts to null pointer or null handles. I.e. use String^ myContainer = nullptr; -hg Thank you very much. That did it. ...Show All

• Markus Fritz Problem loading dll created by VisC 2005

  Hi, I converted a C++ project from VS .NET 7.1 to VS .NET 8. The project uses old fopen methods and similar. Under 7.1 the project compiles and runs, but under 8, I am unable to run. First, when running the application, it complains about missing msvcr80.dll. Then, when I locate it (somewhere) on the computer, I get the error that the application tried to load the dll in an illegal manner. When searching for info on this, I stumble into manifests, and I see that the manifest should contain some lines about the msvcr80.dll, version etc. But my manifest file is empty. It only contains this information: < xml version="1.0" encoding="UTF-8" standalone="yes" > <assembly xmlns="urn:schemas-microsoft-com:asm.v1" manif ...Show All

• mmmmBeeeer Why is base class destructor unresolved in Release mode (VS2005)

  Abstract base class, Foo, exists in library F Derived class (from Foo), Bar, exists in library B Module M uses Bar (but never Foo directly). Linking M to B satisfies all external references in Debug mode. In Release mode, however, linking of M complains that the reference to Foo’s destructor is unresolved. This seems inconvenient. It is caused by optimization because if you disable the optimization on M, there is no link problem. Can this behavior be justified Does anyone understand what sort of optimization is happening that causes this behavior Is there a way around this other than either disabling optimization or linking M to F (also setting M’s C++ Properties/Optimization/Whole Program Optimizat ...Show All
