From: AA2e72E on 4 Feb 2010 07:26 [I would have asked this in a C++ forum but the one I found is empty!] System.IO.Directory.CreateDirectory(path); return System.IO.Directory.Exists(path); I want to bury this in a C++ Win32 Project. My effort so far (that does not work and I do not understand the error messages) is: #using <mscorlib.dll> using namespace System; using namespace System::IO; bool* _clrcall;bool CDirectory(String path) { DirectoryInfo d = Directory::CreateDirectory(path); return (d.Exists(path)); } I get Error 1 fatal error C1190: managed targeted code requires a '/clr' option WCALL_DLL Error 3 error C3149: 'System::String' : cannot use this type here without a top-level '^' Error 4 error C2664: 'System::IO::DirectoryInfo::DirectoryInfo(System::String ^)' : cannot convert parameter 1 from 'System::IO::DirectoryInfo ^' to 'System::String ^' Error 5 error C2064: term does not evaluate to a function taking 1 arguments I don't know why I am getting Error 1 as I have set Common Language Runtime Support to Common Language Runtime Support (/clr) Many, many thanks.

Here are the appropriate active groups. For ISO standard C++: microsoft.public.vc.language For C++/CLI: microsoft.public.dotnet.languages.vc Both groups have active "volunteer" members who are very good at what they do, so I'm sure you'll find the help you need.

Thanks, I've reposted the question. On reopening the project, I am no longer getting Error 1.
