From: Peter Gordon on 9 Jan 2006 07:28 I have to use the function GetNamedSecurityInfoW and it needs a pointer to a file in the format LPWSTR. How to I convert a wxString to LPWSTR ?

From: Peter Gordon on 9 Jan 2006 08:30 I am using pure Unicode. If I have GetNamedSecurityInfoW(L"c:\\temp\a",...... the code works. If I have s = wxString(_T("c:\\temp\\a")) ; GetNamedSecurityInfoW(s.c_str(),... it fails. The documentation says that for GetNamedSecrityInfoW file name needs to be null terminated. So I tried, s = wxString(_T("c:\\temp\\a")) ; wxChar d('\0') ; s = s + d ; GetNamedSecurityInfoW(s.c_str(),... and it still fails. Can someone suggest the correct incantation?

From: Iulian-Nicu Serbanoiu on 9 Jan 2006 08:51 Try this and see what happens: GetNamedSecurityInfo(_T("c:\\temp\\a")); s = wxString(_T("c:\\temp\\a")) ; GetNamedSecurityInfo( s.c_str() ); without the last W . It is possible that you are using wxWidgets library not in the Unicode build ( i think ). Also you could test by displaying some message boxes to test that the strings received as parameters are identical. the strings are: L"c:\\temp\a" and s = wxString(_T("c:\\temp\\a")) ; s.c_str(); Try this with this function ::wxMessageBox or the winapi function MessageBox Also try this to see what type of wxLibrary ( unicode or not you have ) #ifdef _UNICODE message box saying we have unicode #else message box saying we don't have unicode #endif No more ideas for the moment but maybe this will help, Iulian Peter Gordon wrote: >I am using pure Unicode. > >If I have > >GetNamedSecurityInfoW(L"c:\\temp\a",...... > >the code works. > >If I have >s = wxString(_T("c:\\temp\\a")) ; >GetNamedSecurityInfoW(s.c_str(),... > >it fails. > >The documentation says that for GetNamedSecrityInfoW file name needs to >be null terminated.

You were spot on. I was running a test program and had forgotten to set the Unicode flag. Thanks for your help.
