• jdang Application Verifier and MFC app

  I've just tested my application with the Microsoft Application Verifier 3.2 to see if it finds anything BoundsChecker doesn't find and to run the Standard User Analyzer. Actually the Application Verifier always throws an error when I quit my application. I've then created a new MDI application with VC6 and tested that one, and I got the same error. Then started VS2005 and created a new MDI project, and again, same error when I quit the application. The error occurs somewhere in ExitProcess of the CRT. Is this a problem of the Application Verifier or the CRT ======================================= VERIFIER STOP 00000301 : pid 0x3F0: Invalid TLS index used for current stack trace.  FFFFFFFF : Invalid TLS index.  00 ...Show All

• Ray Dyce DLL Conflict

  Hi there! I wrote an XLL(a user-defined function for Excel, using C++) that evaluates algebraic expressions using binary trees, stacks and so on. The good thing is, it works perfectly. But then I need to make it work using a cluster, that is, parts of the expression must be sent to the cluster’s master computer and it will send these parts to be calculated by some slave computers. Ok. However the thing is, I can’t even connect to the cluster. I’m using Microsoft Compute Cluster Pack. When I put together the code for my XLL, that was partially created by an application named XLLPlus, and the cluster-specific code, that uses COM, a DLL conflict happens. There is a double definition of a DLL’s entry-point, DLLMain. One of the DLLs is from XLL ...Show All

• Frederic Buchet native C++ to CLI

  I am having some code written in C++, I want the code to be managed though, or the interface managed at least. The author has no experience with CLI (I have no experience with either!) and I want to persuade him to go this route. It seems to me that if the /clr switch is set and because of “It just works”, then he can pretty much retain native style programming techniques. I am right about this If not is it that much of a learning curve to adopt CLI Thanks for you help in this matter Julian As long as you code your computational stuff in C++, you are getting the perf you need. What you want to minimize is the managed to unmanaged transistion. This means a ...Show All

• cwinfough How to rebuild the C++ STL library for Visual Studio 2005?

  I have made some changes to (to solve C2248 basic_ios problem) the VC8 STL library. How do I rebuild the C++ STL for Visual Studio 2005 Hi Einaros, I am currently in Cape Town South Africa . I will contact Microsoft tomorrow, but my guess is that it will take a while to get it (things are a little slower in Africa …). Would it be possible for you to email ( devilspeak2004@yahoo.com ) the patch to me I would greatly appreciate it. Just so I've got this clear. I followed the link and have to pay a couple of hundred bugs to get the patch for this Which of the following applies here : a) MS is ripping us off. b) I can't read the links properly. ...Show All

• explode Won't jump to ErrorList when building

  Hi, When building my C++ projects in VS2005 and having errors and warnings, the IDE will not jump to the ErrorList window when done, it stays on the output window. The ErrorList is docked together with the Ouput window (and some other windows). I've seen this work on other computers. Any ideas why it's not working on mine /Mikael That's it. Thanks. I've noticed that my settings differ from others in several ways. Don't know why though. But I was able to fix it by replacing my "CurrentSettings.vssettings" with one from another machine. /Mikael You can configure VS2005 to do this from the application options. 1) Open Tools-->Options from th ...Show All

• KLankford Program closing right after opening

  Hi all, I have tried to compile a program from the book C++: A Beginner's Guide by Herbert Schidt. The problem I encounter is when I try to run the program from the folder, that is the .exe file I believe located in: C:\Documents and Settings\Peter\My Documents\Visual Studio 2005\Projects\sample1\debug This simply closes after opening. Am I running it from the correct location I can't find an executable file anywhere else in the sample 1 folder. I believe it's a CLR project. I'm just wondering what I'm doing wrong. Thanks Just out of curiosity...I had the same problem and after the build, it tells me I have a warning. It says that "getch ();" is depecrated. (Adding those two lines of c ...Show All

• rhinoishere error LNK2001

• Doan Duc Long C++ Windows Forms Project Header Files

  Hi, Somewhat of a very basic question here. I am using C++/CLI. Why with a windows form project is all the code in the .h file Thanks Jeff Hi, thanks for the response. I have never really seen any explanation on MSDN or documentation that I have so I was not sure. Seems a bit strange though. Usually you just see class interfaces in the .h file and implementation in the .cpp file. Thanks Jeff To make it easy on the form designer. It only has to parse one file instead of two. ...Show All

• TboneToo Fullscreen mode is not fullscreen, VC++2005

  I've been using VC++2005 for about 4 months and am fairly happy with it on the whole, but it does annoy me that fullscreen mode is not fullscreen. I find it makes coding easier if I can see more code on the screen at the same time, because it puts what your doing into context. In VC6 fullscreen meant fullscreen, yet in VS2005 it doesn't. The menu bar, those dropdown function selecting boxes, the status bar, and those tabs remain on the screen - all stuff which can be accessed through keyboard. Anyway just a comment of mine, probably noone will agree lol. There are a few things you can do to maximize your real-estate though the options are not imediatly apparent. You can turn off the status bar ...Show All

• MerleN CScrollbar Question

How do I get ahold of the position while I'm scrolling Ok well I got some scrolling positions coming out in my trace.  I'm wondering why the nPos isn't updating with the correct position.  It's scrolling between the max and min in negative and positive integers as so: Position = 0 Position = 3593 Position = 4790 Position = 9580 Position = 14371 Position = 19161 Position = 26346 Position = 32334 Position = -27214 Position = -21226 Position = -17634 Position = -11646 Position = -5658 Position = 330 Position ...Show All
