.NET Forum / Languages / Managed C++ / June 2007Using VS2005 on a project that earlier used VS2003
Hello! What is the right way to go when I have a C++ project that earlier used VS2003. When I compile now I get a lot of compile error. //Tony Hi Tony, > Hello! > > What is the right way to go when I have a C++ project that earlier used > VS2003. > > When I compile now I get a lot of compile error. Managed or unmanaged C++? For managed: learn the new syntax for C++/CLI and change the code. For unmanaged: what are the errors? Typically you will get a lot of warnings about unsafe APIs which you should replace with safer versions. -- SvenC Hello! It's manage code. Is the best or maybe the only way to take each compile error and correct it. I just wonder if there exist some way to let the vc2005 behave like vs2003 and compile without error. //Tony > Hi Tony, > [quoted text clipped - 14 lines] > -- > SvenC > Hello! > [quoted text clipped - 4 lines] > vs2003 > and compile without error. /clr:oldSyntax might help (although I never tried it as I upgraded from Managed C++ to CLI/C++). Boris > [...] Hi TonyJ! > It's manage code. You have three chances: 1. Set your compiler option to "/clr:oldsynatx" 2. Review your code line-by-line 3. Use the "VC++ 2003 Managed Extensions to VC++2005 C++/CLI Conversion Tool" http://www.microsoft.com/downloads/details.aspx?familyid=a3581805-1af2-4c34-9d0e -6029cc078441&displaylang=en I would prefer the option 3 ;) Greetings Jochen > Hello! > [quoted text clipped - 4 lines] > > //Tony Are you getting errors or warnings? Or both.. Please send a sample of the errors and warning you get. You should be able to migrate from 2003 C++ projects to 2005 C++ projects fairly easily, but it depends on how compliant your C++ code was. Do you have any managed code in the C++ project? Are you using many of the older C style functions? (such as ones found in stdio.h). Using these will often give you warnings. Sometime you can simply disable these warnings for the time being. Josh
