• UmairKhan enum declaration - newbie can't do it! :)

  i'm using VS C++ 2005 native, and I can't seem to get an enum declared. I can do it in a CLI app, but not native C++. There was a larger example in my book, but I can't get a simple app that ONLY declares the enum to compile. Here's the error. Following is my code. I know the enum declaration is in the main() function; I've also tried declaring just before the main() function. Thanks in advance for any suggestions/help!

• Magannahan Skjellifetti 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 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 other posts it seems that it's possibly neede ...Show All
