Bjorn Liene Gundersen wrote: I dont understund why my function works up to 110 but no higher number, ener = (Datapacket[0] % 10); Temp = Temp + Asci[ener]; This should return # ones, and it does, until number bigger than 110, then the last asci character added to the outputstring is 0 and a strange symbol. Can you understand why I'm sure there's sound reason. Rather than spending time analyzing your code, you should focus on how the problem *ought* to be solved :) And by that I don't mean that you should use the mock function I typed up (which may very well have issues of its own -- I didn't check. Use the standard library functions supplied to use, such as ITOA, or the stringstreams found in the STL. Tag: Visual C++ General Porting To Visual Studio 2005 Visual C++

    - project for matlab mex: MFC DLL versus Win32 DLL Hi, I am trying to use VC 6 to compile c files to matlab mex (a kind of DLL). VC 6 gives me two type of dlls:MFC and Win32. i tried both. they both works fine on my computer (i compiled them on my computer). then on another mathine, the matlab (thus some matlab lib files i included in the project) is in aother directory (different from mine). Now the Win32 type mex file works fine, but the MFC type mex file does not work. Does this have something to do with the settings of the linker or compiler my codes are exactly the same for Win32 DLL and MFC DLL. can anybody give me some clue where i should pay attention to in codeing the MFC DLL thank you very much for the help.

    - [Vista & IpAddrTable] How associate Guid with dwIndex to get the right table. Hello here, I'm trying to get the current ip of an wireless network interface connected. On xp,with wrapi, i know how to find the right Index to check the good ip addr table. But on vista, with wlanapi, i use guid to work with the different interface, and at this point, i dont find the way to associated the good ip addr table with the good interface cause i didn't know the dwIndex. Is there any way to get the dwindex link to the guid of an interface May someone know an another way to do it Thanks for you help Regards Yannick Tag: Visual C++ General Porting To Visual Studio 2005 Visual C++

    - Signing Resource DLL Hi, I was trying to sign my C++.Net application with a strong name key file by setting in the visual studio's Project Settings -> Linker -> Advanced -> Key File option. The assembly itself seem to be signed correctly; however, the resource DLL (mainly localization resources) are not being signed with that key file. If I specify the AssemblyKeyFileAttribute in the AssemblyInfo.cpp and remove the Key File settings from project settings, the resource DLL will be signed correctly but I got a warning 810100b3 during manifest embedding saying my assembly "is a strong-name signed assembly and embedding a manifest invalidates the signature. You will need to re-sign this file to make it a valid assembly." and my program will not run due to strong name validation failed. Then if I put back the Key File settings from the project settings and keep the AssemblyKeyFileAttribute in the AssemblyInfo.cpp, I got a warning saying the "/Keyfile option override assembly settings". Not sure if duplicating the key file settings is the correct way of doing things... Does anyone know what's the correct way of strong-name signing my assembly with all resource DLL signed as well Thanks! Tag: Visual C++ General Porting To Visual Studio 2005 Visual C++

    - Win32 Thread Interleaving Hi, I read some post for win32 thread application and thought if you guys can hep us. we are developing trading platform for different exchanges and facing a strange problem. Our application creates two threads both threads are running for indefinate times (means there is no sleep in thread loop function). Thread 1 will always check the queue for possible work to be done and Thread 2 always listens the network broadcast. The code is something similar to void *ThreadAFunct(void *arg){ While(true){ int workAvailable = CheckQueue(); //.... if(workAvailable){ LockMutex(sharedMutex); //do some work UnLockMutex(sharedMutex); } //..... } } void *ThreadBFunct(void *arg){ while(true){ //..... LockMutex(sharedMutex); //ListenForBroadcast... UnLockMutex(sharedMutex); //........................ } } Both threads uses same mutex. and for acquiring and releasing mutex we are using EnterCriticalSection and LeaveCriticalSection functions. Now problem we are facing is, in windows XP hyper threaded processor, threads get the mutexes in just a few milliseconds and never had any problem with thread interleaving, threads releases after few milliseconds and other thread acquires mutex in very little time. But we are seeing different behaviour in windows 2003 server (SP1) hyper threaded machine. Thread doesn't interleave perfectly like XP, sometimes a thread runs for long time compare to other thread (I used timers and found out that Thread B gets most of the processor time compare to thread A.) And often (most consistantly and probably root of all these problems) thread A waits for very long time just for acquring mutex (sometimes more than a min some time just a second). I am not getting why it works perfectly fine in windows XP. The same application is running for over 3 months (on XP) but on windows 2003 it has these problems. One possible solution would be to put Sleep() in Thread B after reading certain number of broadcast. And it works but still can't get bottom of the problem. I wrote same program using WaitForSingleObject() and it works fine with that, so wondering it might be something to do with the CriticalSection functions. I even tried setting different values for Win32PrioritySepration but didn't worked. So any suggestion would be helpful.

    - [MFC] Menu problem Hi there! I'm creating an app with mdi interface, where child windows are created from custom class CSetupWnd derrived from CWnd. The problem is that I can't show a menu in these children windows! app is using dll SetupCore where CSetupWnd is declared and another project - SetupApp - uses it. When you click File/New item in main window it replaces its own menu with menu designed in SetupCore.dll - and the same menu should be also visible in child windows, but it is not! I've tried many ways to make he app work as I want, but nothing helps. Please write me a piece of example code that could help me. And sorry about my poor english Greets, Tag: Visual C++ General Porting To Visual Studio 2005 Visual C++

    - RegSvr32 and global data and extern problem PRMARJORAM wrote: The client is a MFC COM DLL that depends on an old C DLL explicit linking via lib file. If i call a few functions from the MFC COM DLL into the C DLL is all ok. So this proves it can find the DLL ok. If i add a few calls via function pointers again from the MFC COM DLL to the C DLL, then this is when the error message occurs. So why would it not like C function pointers If i link the C DLL statically i rebuild the project as a static lib, then all is fine. Although this is not an option, but just throws some light on the problem So why would regsvr32 fail to register a COM DLL than implicitly links to a C DLL which declares some pointer to functions and these are used from the client What I understand from the above is that your COM dll wraps some calls to a C DLL. The client calls the COM dll and the COM dll in turn calls the C dll. When you use implicit linking ( to the C dll) your COM dll registers OK and when you use explicit linking (dynamic linking) you are unable to register the COM dll. When regsvr32 is called the target dll and it's dependencies are loaded. AFAIK dynamic linking does not count as a dependency in this context. So this is perplexing indeed. You can try the following : 1) Since the error message says : error PRJ0050: Failed to register output. Please ensure you have the appropriate permissions to modify the registry. Check if you have the neceszsary permissions. 2) Try building the dll and calling regsvr32 manually instead of using the IDE. Check if you get the same response. 3) Try checking your COM dll's dependencies using Depends.exe; this may throw some light on the issue.

    - Visual C++ Path I don't want to hurt your feelings, but I find it funny how many people start learning programming because they want to make games. Unfortunatelly, as a beginner, it's hard to understand that games programming is a dificult task, because a game is a complex program (well, that also depends on what kind of game). Games like the ones you play at home or with your friends were developed by teams that put months or years into them. What I'm trying to say is that learning basic stuff like structs, functions or STL isn't enought to build games. My recommendation is that before you start thinking about that you learn very well at least C++, graphics programming, networking. But if you intend to build a 3D game by yourself, trust me, you'll never make it happen. Or ir will take so long you'll get bored. Tag: Visual C++ General Porting To Visual Studio 2005 Visual C++

However this just goes to further point out the fact that the C++ Form serialization and deserialization need to be fixed. I am still working with Microsoft on this issue and hope to have more details in the near future.

    - CRT assembly versions confusion :8.0.50608.0 vs 8.0.50727.42 That's only part of the story. The way it works for applocal is that the version number embedded in your application EXEs and DLLs has to match the version number that is contained in the applocal Microsoft.VC80.CRT.manifest file. So for example, on a clean machine with nothing in the WinSxS folder: Myapp.exe and mydll.dll contain an embedded 8.0.50508.0 reference The copied Microsoft.VC80.CRT.manifest file must also contain the version number 8.0.50608.0. The CRT DLLs contained in the same folder as the manifest file can be of any version number (in my experience). As to your question about the confusing versioning 8.0.50608.0 instead of the proper version number, I think that the original idea was that any beta app already built and shipped (on golive license) would automatically redirect to the RTM version through policies. But I think they must have forgot to change the _CRT_ASSEMBLY_VERSION in the CRT source code to 8.0.50727.42 before building for RTM versions. Luckily though, it seems to work, even with the old version number. Unfortunately though, the same story cannot be said for MFC80LOC DLLs in SP1. In this case it was really messed up for applocal (no proper solution) Tag: Visual C++ General Porting To Visual Studio 2005 Visual C++

Using C++ you rather use the redesigned ones (without the .h extension) thus: #include <fstream>. The only thing you need to remember is that everything inside the standard C++ headers is defined inside the namespace 'std'. Thus, you need to map the namespace to your application accordingly: Code Snippet // Using the full member name, including the namespace it belongs to: std::cout << "Hello World"; // By taking advantage of using declarations: using std::cout; // This declares 'cout' in the current scope as synonym for 'std::cout' cout << "Hello World"; // By taking advantage of using directives: using namespace std; // Specifies that the current scope can refer to names in the 'std' namespace without using the full qualifiers. cout << "Hello World"; // Using aliases namespace x { namespace y { class z { ... }; } } X::Y::Z // Full qualifier for 'z' namespace w = x::y; // Declares 'w' as an alias for namespace 'x::y' -anthrax- wrote: 1>.\SampleGroupRecordView.cpp(4470) : error C2668: 'pow' : ambiguous call to overloaded function 1> C:\Program Files\Microsoft Visual Studio 8\VC\include\math.h(575): could be 'long double pow(long double,int)' 1> C:\Program Files\Microsoft Visual Studio 8\VC\include\math.h(527): or 'float pow(float,int)' 1> C:\Program Files\Microsoft Visual Studio 8\VC\include\math.h(489): or 'double pow(double,int)' 1> while trying to match the argument list '(long, int)' Well...all this says is simply that the compiler is not able to resolve your function call. The function 'pow()' is overloaded for usage with different data types.

You should create a small program you can use to test things like that and then post only valid code. Note that the parameter is "&blah", which is a pointer to blah. In the class, the parameter for someFunction is not a pointer. Something that would be valid would be: someClass blahblah = someFunction(blah); In reality, you are unlikely to do that but that is best explained in a tutorial or book.

    - C++/CLI Tracking reference limitation Effectively, C++ native references translate to native pointers in CLR speak. It is perfectly possible to have a native pointer to an object of a generic parameter type. However, as you've probably noticed by now there are a lot of things in VC++'s CLR support that are less than perfect. The limitation, that managed pointers cannot be members comes from the CLR. I asked for functionality to overcome this quite early in the alpha days, basically supporting automatic allocation of objects of a given type and forcing all function calls inline. Brandon said they had considered and dismissed something like this. IIRC they called it "stackonly" types. I doubt that there is a good solution for your problem. You may be able to pin the underlying object via the library somehow, but then it won't be beautiful. -hg Tag: Visual C++ General Porting To Visual Studio 2005 Visual C++

Hello, I'm trying to port a program that was written in Visual C++ 6.0 to Visual Studio 2005. After not having much success I tried to port it to VS2003 and was able to get the program to work. I then took that port and tried to get it to work in VS2005 and was able to get most of it to function but one part.

I have a edit box and a slider box, either one can be used, to enter a floating value between 0 and 1. When you try to select either a message pops up saying "Please enter a value between 0 and 1000" and you are not able to change any values before this message pops up, and then a debug assertion error is given.

I have checked over all the math and it remains the same as the VC++6.0 and VS2003 that both work, and the only part of the code that was changed was when some pow() functions where used to solve and problem with ambiguity (I cast the values as being double since I am under the impression that VC++6.0 pow() fucntion could only take doubles)

Any ideas of where to start would be great.

Thanks

Simon
