    - Warning C4482 - Enums C++ is certainly harder to master than VB, but its popularity continues due to its flexibility and "to-the-metal" code generation. C# is a great compromise--you get the flexibility of C++, the safety and "intellisense" of VB, but at a cost of performance. Brian Tag: Visual C++ General C# program link C++ lib/dll Visual C++

    - About title My application is based on Doc/view architecture. I want to change my title. Since my application supports for many languages title characters will change frequently as per the language. In main application i could change the title by specifying SetTitle() method in mainframe. But while calling AfxMessageBox() it takes English character itself. In some article they said i have to change m_pszAppName in InitInstance(). Even though it doesn't change. it will be in English only. I have all languages rc file. So can u please suggest me the solution Tag: Visual C++ General C# program link C++ lib/dll Visual C++

    - LNK2028 and LNK2019 when porting to managed C++ There is a difference between managed and unmanaged code - with managed code the optimizer does not inline anywhere as much as it does in unmanaged code (mostly because the JIT can do this) therefore definitions of these functions are required - hence the need to link in the library.

    - Can I make a program to disable aero? I want to make a program in C++ for Windows Vista that controls my aero settings. What I basically want it to do is come up with a menu that has a button that says Start Game Mode.

    - Includes in Mixed-Mode DLL I have a DLL with a Managed Class and an an Unmanaged Class and and having include problems. I have built previous native mode Assemblies where the includes are against header files in the Vista SDK. There are ambiguities with mixed mode DLLs however. On compliling, I receive the following error: 1>c:\program files\microsoft sdks\windows\v6.0\include\ocidl.h(6238) : error C2872: 'IServiceProvider' : ambiguous symbol 1> could be 'c:\program files\microsoft sdks\windows\v6.0\include\servprov.h(103) : IServiceProvider' 1> or 'c:\windows\microsoft.net\framework\v2.0.50727\mscorlib.dll : System::IServiceProvider' The include is intended for the former rather the latter.

    - System.StackOverflowException with Threading Did you add the breakpoint If you did, the exception shouldn't have been thrown, as the code would break and the debugger would come into focus. Add a breakpoint, launch the application within the debugger and have it break. The point is, as I've said, to see if the same function is being called over and over recursively. As for the stack size, I wouldn't touch that. Finding the cause of the problem is a better way to go about it at this point. Tag: Visual C++ General C# program link C++ lib/dll Visual C++

    - error LNK2019: unresolved external symbol - when trying to sort an std::deque Hi! I'm migrating code from Visual Studio 2003 to Visual Studio 2005 and have run into problems with a rather simple piece of code that compiles and links fine in 2003 but fails to link in 2005. Basically, I have a deque class that contains pointers to objects of a simple class. I defined a sorting predicate function and try to sort the queue. Here's the essence of what I'm trying to do - I've stripped the code down to bare bones: Code Block class TestDeque { }; static bool ComparisonFunction( const TestDeque *e1, const TestDeque *e2) { return true ; } std::deque<TestDeque *> MyQueue; std::sort(MyQueue.begin(), MyQueue.end(), ComparisonFunction); This results with the following link error: PMAN_ServicePool.obj : error LNK2019: unresolved external symbol "bool __cdecl o perator<<class std::_Deque_iterator<class TestDeque *,class std::allocator<class TestDeque *>,0> >(class std::_Deque_iterator<class TestDeque *,class std::alloc ator<class TestDeque *>,0> const &,class std::_Deque_iterator<class TestDeque *, class std::allocator<class TestDeque *>,0> const &)" ( $ MV $_Deque_iterator@PA VTestDeque@@V $allocator@PAVTestDeque@@@std@@$0A@@std@@@@YA_NABV $_Deque_iterato r@PAVTestDeque@@V $allocator@PAVTestDeque@@@std@@$0A@@std@@0@Z ) referenced in fu nction "struct std: air<class std::_Deque_iterator<class TestDeque *,class std: :allocator<class TestDeque *>,0>,class std::_Deque_iterator<class TestDeque *,cl *** std::allocator<class TestDeque *>,0> > __cdecl std::_Unguarded_partition<cla ss std::_Deque_iterator<class TestDeque *,class std::allocator<class TestDeque * >,0>,bool (__cdecl*)(class TestDeque const *,class TestDeque const *)>(class std ::_Deque_iterator<class TestDeque *,class std::allocator<class TestDeque *>,0>,c lass std::_Deque_iterator<class TestDeque *,class std::allocator<class TestDeque *>,0>,bool (__cdecl*)(class TestDeque const *,class TestDeque const *))" ( $_U nguarded_partition@V $_Deque_iterator@PAVTestDeque@@V $allocator@PAVTestDeque @@@ std@@$0A@@std@@P6A_NPBVTestDeque@@0@Z@std@@YA AU $pair@V $_Deque_iterator@PAVTes tDeque@@V $allocator@PAVTestDeque@@@std@@$0A@@std@@V12@@0@V $_Deque_iterator@PAV TestDeque@@V $allocator@PAVTestDeque@@@std@@$0A@@0@0P6A_NPBVTestDeque@@1@Z@Z ) If I change MyQueue to be Code Block std::deque<TestDeque> MyQueue; everything's fine.

    - How can I cancel OK button click event? Hi I am calling a form CreateNewSimulation, where a user enters some data about the simulation they are running: CreateNewSimulation ^ thisnew = gcnew CreateNewSimulation(gamelist); if (thisnew->ShowDialog()==: ialogResult: K) { .... do something.... } On form CreateNewSimulation, I have an OK button But I need to check what they have entered is valid BEFORE allowing the dialogresult to be OK private : System::Void Button_OK_Click(System: bject^ sender, System::EventArgs^ e) { bool dataOK = check_name_and_data(); // check whether the data entered duplicates existing simulations and matches all the conventions needed if (dataOK) { // save some info for future use this ->thisgame->Game_Descr= this ->Game_Descr->Text; this ->thisgame->SavePointDescr= this ->SavePointDescr->Text; this ->thisgame->path_1= this ->Game_Descr->Text;; this ->thisgame->path_2= this ->SavePointDescr->Text; this ->thisgame->Validity= false ; } //else NEED TO CANCEL THE OK click to prevent return to Form1!; <------ the OK event needs to be cancelled! } }; Obviously, what I currently get is that when my 'dataOK' check fails, I still end up sending the dialog_result OK back to my main form. Can anyone advise how I can solve this problem Thank-you Tag: Visual C++ General C# program link C++ lib/dll Visual C++

    - Stepping through VC8 SP1's debug CRT ? PDB File available? For years I have used older versions of MSVC and their "debug" C run time DLLs, e.g. MSVCRTD.DLL . I was able to step through the code in the debug CRL DLLs. This past week, I installed MSVC 2005 Express Edition, SP1. Now it seems that I can no longer step through any of the CRT functions. It seems I need a PDB file for MSVCR80D.DLL and I don't have one. So, can you tell me how to get the PDB file, or how to step through SP1's MSVCR80D.DLL functions Tag: Visual C++ General C# program link C++ lib/dll Visual C++

    - Cannot get debugging to work with VC++ 6.0 Just to clarify, it's not the compiler output that you are seeing, it is the debugger output. All it means is that the debugger is unable to load debugging information about those dlls (which are automatically included as part of the project). The debugger doesn't have "special rules" for particular dependencies, and so checks if there is debug information for any loaded binaries. As for VC6, it is pretty nasty compared to 2005, but only because we've got 2005. It's still an immensely powerful IDE. Tag: Visual C++ General C# program link C++ lib/dll Visual C++

    - Class help Hi, Little_Dice what Brian and Marius recommended is good programming practice (not mandatory to do so) to keep you away from same kind of problem ever. You just simply to make sure all your header file has following structure: // xyz.h #ifndef __XYZ_H__ #define __XYZ_H__ // all your header file content. #endif // __XYZ_H__ then you can get rid of your problem. Use this structure to avoid multi-include header file has a term called "include guard", just like Brian and Marius mentioned. furthermore, there is no need to keep your guard something like __x_x_, it could be any string that valid to be a macro.

    - This application has failed to start because the application configuration is incorect. Reinstalling the application may fix thi I am having the same problem and am in process of researching. Found this Thread. I checked my Property Pages and find all options are correctly set as specified: ---- First, make sure that your Linker properties include "Generate manifest"; it's by default the file "$(IntDir)\$(TargetFileName).intermediate.manifest". Then, check that the "Manifest tool" "Input and Output" contains "Embed Manifest" -- "Yes". ---- Yet, the failure still occurs. I read the mentioned article ms235591. Seems complex to me. Seems that VS2005 should take care of the problem without all the make file editing. I will read the other articles mentioned in this thread and get it figured out. Guess this is mostly an editorial comment that VS2005 should take care of the embedding problem if the options are correctly selected. But... do you know... MUST I do the makefile edits per MS235591(VS.80) And, doesn't the IDE create new makefiles all the time; won't my edits be lost when the IDE overwrites Tag: Visual C++ General C# program link C++ lib/dll Visual C++

    - destructor of global objects not called (CRT without managed code) The linker merges all input sections (from the object files) of the form abc$xyz into a single output section abc where the input sections are lexically sorted. .CRT is again merged into the output sections (you can take a look at the map file to get the basic idea) What the runtime code does is something along the lines of placing __xc_a in a section ".CRT$XCA" and __xc_z in a section ".CRT$XCZ" hence, everything that goes in section .CRT$XCBxy - $XCYxy goes in between these two symbols (it's the linker's job to make sure). I don't really recall where RTC_Terminate should be, but I seem to recall that there is a separate initializer list for more basic stuff, but that goes in .CRT$XI, IIRC. Either way, I would simply try to debug the problem: does your initialization code actually call into atexit If it does, just place a data breakpoint the address where the pointer to the atexit dtor is stored. I think there is some arcane option to replace atexit in the init_seg pragma, but I'm not sure if that was really in VC. -hg Tag: Visual C++ General C# program link C++ lib/dll Visual C++

    - How to watch each element in a vector when debugging Hi all, I have no idea how can I watch each element in a vector when debugging under VS. For example, when I set a break point at the 2nd line and execute it step by step, I cann't find a way to see each element in the watch window (except the first one). Code Snippet vector< int > iVec; for ( int i = 0; i < 3; i++) { iVec.push_back(i+1); cout << iVec.at(i) << endl; } When I put "iVec" as the varialbe name in watch window, it does show something. However, as the loop goes on, it always displays the first element under "_Myfirst". In this case, it's always "1". But when I try to put "iVec[1]" or something to see the element other than the first, it has error messages such as "overloaded operator not found". How can I view the second element in the vector What should I type as the variable name in the watch window Thanks! Tag: Visual C++ General C# program link C++ lib/dll Visual C++

    - C++ Web Reference Problem - Calls to proxy class fail with WSAECONNREFUSED Hi I believe I have found a bug in ZEvtSyncSocket. A proxy class generated by adding a web reference to the project fails with the following error: 10061 WSAECONNREFUSED The attempt to connect was forcefully rejected. ZEvtSyncSocket is implemented in atlspriv.inl. The problem is caused by the call to address.FindAddr in line 115 returning an address in IP6 format that is subsequently cast to SOCKADDR (an IP4 structure) in line 131. A work-around is to force the call to FindAddr to return an IP4 address by changing line 115 from: if ((m_dwLastError = address.FindAddr(szAddr, nPort, 0, PF_UNSPEC, SOCK_STREAM, 0)) != ERROR_SUCCESS) to if ((m_dwLastError = address.FindAddr(szAddr, nPort, 0, PF_INET , SOCK_STREAM, 0)) != ERROR_SUCCESS) Can Microsoft confirm this problem please Is a proper fix available Thanks Jeff Tag: Visual C++ General C# program link C++ lib/dll Visual C++

Re: Visual C++ General C# program link C++ lib/dll

crescens2k

If your C++ code is native then you will need to use mixed mode C++ or Platform Invoke to get access to them. If you are using Managed C++ then you can just reference it like any normal CLR assembly.

A note though, if it is a static library then you will need to create a dynamic library out of it.

Thank you!

How do use mixed mode C++ or Platform Invoke to get access to them.

I use ["xxx.dll"] in C# program. It cannot compile.

Best Regards!
