    - ReadDirectoryChangesW does not provide the renamed filename when renaming a newly added file Regular renaming works fine: 1. An existing file 3.txt exists at the c:\scripts directory 2. Renaming 3.txt to 4.txt, the following code works fine. Renaming a newly added file does not work: 1. Add 5.txt to the c:\scripts directory 2. Rename 5.txt to 6.txt Noticed 6.txt is not printed.

    - invalid or corrupt file: duplicate COMDAT error encountered while migrating to Visual Studio 2005 I have a solution comprising of some 20+ projects, which I am trying to migrate to VS2005 (I was using VS2002). One of the projects is throwing up this linking error: fatal error LNK1179: invalid or corrupt file: duplicate COMDAT <mangled form of the function CXYCollection::get_Count> (Basically the mangled name of the function just after QueryInterface) The project makes a heavy use of class templates and I think it is the reason behind the error.

    - Linker Error It may be because of that you have not set visual studio to use the Platform SDK path as include or lib path. There has two way to resolve this problem: 1) Lanuch the follow program: Start -> All Programs -> Microsoft Windows SDK -> Visual Studio Registration -> Integrate Windows SDK with Visual Studio 2005 or just double click on "<SDK Path>/Windows\v6.0\Setup\VCIntegrate.exe" or in "Options" menu of Visual Studio 2005, navigate to "Project and Solutions" -> "VC++ Directories", Add "<SDK Path>/Windows\v6.0\Include" to "Include files" "<SDK Path>/Windows\v6.0\Lib" to "Library files" 2) Update the project properties manually: In project properties dialog, set Configuation as "All", and then navigate to "Configuration properties" -> C/C++ -> General replace "Addtional Include Directories" as "<SDK Path>/Windows\v6.0\Include"; navigate to "Configuration properties" -> Linker -> General set "Addtional Library Directories" as "<SDK Path>/Windows\v6.0\Lib" The different is that the first way will affects all C/C++ projects and the second only affects current project.

    - Loop misalignment I'm not exactly certain what problem you are seeing here. There are reasons why you may want to align loops on cache line or instruction prefetch buffer boundaries. However, you shouldn't see huge performance degradation for any but the smallest loops, however unrolling should make a big difference there. These things depend heavily on the specific processor in use. As I understand VC focuses on best performance across IA-32, rather than trying to get optimal performance for a specific CPU (also see the /G switches family). Can you show us some code (both source and ASM) I guess, you might want to use SSE instructions which should also make the instruction prefetch impact smaller. At Intel we used to have a mechanism to specialize functions for a given CPU type (__declspec(cpu_dispatch) & __declspec(cpu_specific), IIRC). You could do the same thing manually with VC, but then there are little to no CPU-specific optimizations in VC (instruction scheduling and selection would probably be interesting for your case). But then I know very little about the microarchitectural differences between recent Pentiums. -hg Tag: Visual C++ General _stat() and long names Visual C++

    - Visual Studio 2005 - C++ - Using structures and vectors together. When you create vendor in the main function it is local to that function's scope. That means that only that function can use it. To use it in other functions either pass it by parameter (preferred) or make it global, or make it a static member of a class. Passing by parameter is the easiest, but you'll need to pass it as a reference to modify it (or a pointer). Tag: Visual C++ General _stat() and long names Visual C++

    - ifstream issues - reading in a data file Yep, with the spaced names, that previous suggestion wont work. If each line has the same amount of chars (whitespace or otherwise) prior to the number, just read them all off the stream before parsing the number. Otherwise your options are to read until you hit a number (and you're sure it's a number not attached to the name), or use a regex library to split the lines apart properly. www.boost.org has a good regex implementation, should you wish to follow that path.

In this case how does the graphics object knows about the Visible region of the window. It does knows that other wise how does it can implement GetVisibleClipBounds function. In my case if after the creation of the Graphics object the window is resized i.e. the visible region is changed, anything drawn on the new found area is not actually drawn.

    - VS2005 / corrupt solution file / References to non existing projects Hi, I have a problem with a number of VS2005 solution files (converted from VS2003). The solution builds but VS keeps updating the solution file which requires a check-out etc. The problem is caused as far as I can see by references to non existing projects! The solution files have references (GUIDs) to project files in the GlobalSection(ProjectConfigurationPlatforms). However some of the references are not listed at the top of the solution file and I cannot find (text search) any project file with such a GUID. If I remove the references then VS adds new references (again to non existing projects). The solution we have contains both vcproj files but also icproj (Intell compiler) with nested vcproj files. Does anybody have an idea what might cause this problem OR Does anybody have suggestions for debugging this problem Thanks in advance TomFr Example: GlobalSection(ProjectConfigurationPlatforms) = postSolution {35A5CE92-181C-4238-965E-870A39BA8D8D}.Debug.ActiveCfg = Debug|Win32 {35A5CE92-181C-4238-965E-870A39BA8D8D}.Debug.Build.0 = Debug|Win32 ... ... {84F9DB36-A887-44F6-B3AA-520FE484DC3A}.Release.ActiveCfg = Release|Win32 <== Non existing Reference. {84F9DB36-A887-44F6-B3AA-520FE484DC3A}.Release.Build.0 = Release|Win32 EndGlobalSection Tag: Visual C++ General _stat() and long names Visual C++

    - Interesting fast interop problem Freqy wrote: I'm creating my own container because none of the existing containers support fast merging, fast splitting, and storing the same key twice. If MS had provided *one* decent container class for C# I wouldn't be having this problem. As for managed allocations, they are precisely what I need to avoid since they lock all CLI threads. I need to access up to 100 of these sorted lists about 50 times a second from up to four threads. Failing to do so in the allocated time causes failures at the real-time end (audio output). Ok, those are reasons good enough for me. This essentially means that you need a native container, with your own allocators as a basis, though. Freqy wrote: The circular reference I'm talking about is the class ListNode { public ListNode next; } circular reference required to make a linked list. I'm remembering why I only use C++ when I have to. I wouldn't be that quick to blame C++ (or C++/CLI, to be exact) ref class Foo { public: Foo^ next; }; Foo^ f = gcnew Foo(); f->next = f; Freqy wrote: Finally: managed vs unmanaged - that's the question I'm asking. At the base level the class must be native (or else I'd just implement it in C#). If I create a native C++ library to do this job, it will obviously store objects of type void*. How will I go passing in and out void*s and casting them all the time Can that even be done in C# The further question is to do with returning a reference to a node in the list. It's really the same question again - if my nodes are unmanaged classes, how can I return/wrap these in an efficient manner What you could do is write native C++ code for the container itself, including all time-critical operations and native memory handling, and follow up by creating a middle tier in C++/CLI. In the C++/CLI code you can call into the native container to insert / extract data, utilize the container management functions (e.g. sort), and so forth. The C++/CLI tier should also do any necessary conversion needed between managed and unmanaged types. Tag: Visual C++ General _stat() and long names Visual C++

    - Wrapper Both articles are quite old. In either case, P/Invoke will play a key part no matter how you go about this. Your options for a solution pretty much limit themselves to 1. writing a managed app which imports specific functions, or 2. writing a mixed C++/CLI appilication, which includes the headers and links the import library of a C++ DLL library. In both cases, you'd re-expose the functionality from the dll through your own wrapper class. Tag: Visual C++ General _stat() and long names Visual C++

    - Allocation problem You don't understand. The error you are getting in new might be a symptom. The actual cause could be elsewhere. The fact that it works using a different version of the compiler might also be coincidental. You might in the future encounter a different symptom using the other version of the compiler. The symptom might be very different eventhough the cause is the same. The actual problem might be very different from what I am describing, but based on the evidence provided so far, the possibility I suggest is possible.

Greetings...

Is there a way to use long file/dir names with _stat function I've tried to prepend path with \\ \ and use _wstat (it works for _wopen) -- it not works: in this case _wstat returns -1 and errno == ENOENT even for short pathes. If not prepend path -- function works nice (but only with short names).

Best regards...

Re: Visual C++ General _stat() and long names

"Use the Source, Luke"....

_stat() has internal wildcard-prevention code that conflicts with the \\ \reallylongname.... facility:

/* Don't allow wildcards to be interpreted by system */

#ifdef _UNICODE

if (wcspbrk(name, L" *")) {

#else /* _UNICODE */

if (_mbspbrk(name, " *")) {

#endif /* _UNICODE */

errno = ENOENT;

_doserrno = E_nofile;

return(-1);

}

You have the RTL sources, so you can answer questions like these quicker on your own.

Re: Visual C++ General _stat() and long names

What information do you expect to get from _stat() that you can't get by calling FindFirstFile() yourself That's basically all _stat() does; cut out the middle man.

Re: Visual C++ General _stat() and long names

_hunter

There is a lot of legacy code, which is used _stat structure...

Also, by some reason, GetFileAttributesW not works with long names to...

Same problem with FindFirstFileW -- it searches something like "\\ \c:\Workspace\test\q" but not searches \\ \c:\Workspace\test\qqqqq...[total 320 q]...

Re: Visual C++ General _stat() and long names

Sdi

As documented (OK, you have to look for it), the \\ \realpathhere convention only lets you extend the total path length; the individual components (i.e. any given directory name or the file name) are still limited to 255 characters each. Open the documentation page for FindFirstFile, follow the "Naming a File" link under the 'lpFileName' parameter, and start reading under "Maximum Path Length".
