• Kapoulkine Arseny Warning C4482 - Enums

  Maybe this isn't the correct forum, perhaps if I ask the question this way. Is there anything wrong with the way I am using the enum below FigureNames is simply an enum {jack, jill, etc..}. When compiling, it get the following warning; Warning 2 warning C4482: nonstandard extension used: enum 'Names' used in qualified name c:\Documents and Settings\Steve Jackson\My Documents\MySchool\C++\Assign1\Assign1\Assign1\Main.cpp 282 switch (name) { case Names::jack: cout << "My name is jack!"; break ; } That's the weakness of C++, unfortunately. Namespaces can be used to get around this limitation. If you want to get rid of those obnoxious error mes ...Show All

• Patrik Olsson Junk values when build in Release mode

  Hello Everybody, I am having a strange problem in one of my VC++ code. I am setting a value in the code, which is getting retrieved perfectly when executed in DEBUG mode. But when I try to execute the same in RELEASE mode only junk values are being returned instead. I am totally clueless. Could anybody be having some idea on this My code snippet is as follows: _bstr_t szStatus = _T(""); _bstr_t szMessage = _T("not available"); // the value that I am trying to set int retVal = -1; try { retVal = m_oSql.GetStatusDescriptionSQL(...); if (retVal == 0) { szStatus = szMessage; // the value is being assigned here } } catch ( CSQLException& e ) { return this->Error(CComBSTR(e.m_szMsg), IID_ICola, E_F ...Show All

• bw12117 Converting System::String to LPCWSTR

  I've been looking for a long time as to how to solve this, and eventually just thought I'd ask. I've been told of A2W, which apparently cannot convert from System::String (so says the compiler error), I've tried converting to a wchar_t first, but the method won't accept it, and I'm running out of luck. Here's what my code looks like now. pin_ptr<const wchar_t> wch = PtrToStringChars(fileName); IAVIFile *aviMedia = NULL; IAVIStream *aviStream = NULL; AVISTREAMINFO *aviSInfo = NULL; AVIFILEINFO aviFInfo; LONG bufferSize = NULL; DWORD length = NULL; wchar_t wcFileLoc; Single vidLength; AVIFileInit(); wcFi ...Show All

• Anand Raman - MSFT C++/CLI destructors and finalizers chaining

  According to the topic "Destructors and Finalizers in Visual C++" in the "C++ Language Reference" implementing a ~ destructor or a ! finalizer automatically chains to base classes which have these semantics after the derived class destructor or finalizer code is run. However it is suggested in that topic that the C++/CLI programmer call the finalizer at the end of the destructor processing. Would not this then mean, in that idiom of calling the finalizer of a class from the destructor of that class, that the order of destructor calling whenever a destructor is run would be: 1) destructor of derived class -> finalizer of derived class ( through suggested call ) -> finalizer of base class ( through chaining ) -> ...Show All

• Nick P Setup Visual C++

  Hi, I am very new to visual C++ and I am trying to use it to compile C code. I have everything setup and I created a hello.c file which basically prints Hello to the console window, but when I run my program the output windw opens and then closes in a flash. Does anybody have an idea why this is happening and if this is the right way to compile C code in Visual C++. Thanks, Sunny It seems that you are doing every everything right. The problem is that with today's computers your program executes before you can see much more than a flash on the screen.

• MartinMalek What is Visual C++ equivalence to C#'s "is" operator?

• StevenR2 msvcr80.dll Problem

  Hi there, can someone possibly tell me why Noton WinDoctor is telling me that 10 executables in the .NET Framework 2.0 cannot access the necessary dll file msvcr80.dll I see that the dll exists in the WinSxS directory and I'm running XP pro. I didn't have this problem until I downloaded the 2.0 framework at windows update. Any advice appreciated. Thanks. Naolin Are you sure that WinDoctor is right Thanks much everyone for the feedback. Sounds to me like its an inconsequential error that Norton will need to address in a future update to look for it in the correct dir. I read on an msn blog somewhere (sorry I cant find it again) that one should not put the dll in the system32 dir but from o ...Show All

• Tim Preston Arrays of Strings

  Hi folks, I'm writing a .NET Winforms project in Managed C++ using Visual Studio 2003 and I'm wondering how I go about having multi-dimensional arrays for String objects I'm vaguely aware of the Array Class, but I'm not sure if this needs to be part of my solution. I've tried a few experiments using the classic C++ method of creating multidimensional arrays, but (of course) this does not work owing to the managed restrictions of the language. In any case, I just need a little direction here - do I need the Array class or is the syntax for this a bit different than what you might expect -Zero array<String^, 2>^ myStringArray = gcnew array<String^, 2>(y,x); Where 2 is the dimensio ...Show All
