wcscpy converted from strcpy

[Tremorblue]

Ansi string to widestring conversion..

Why does this work using ansistring ?

char s[20],t[20];
AnsiString aW;
strcpy(s,t); // Works
strcpy(s,aW.c_str()); Works.

And this does not work using widestring ?

wchar_t s[20],t[20];
WideString aW;
wcscpy(s,t); // This works
wcscpy(s,aW.c_bstr()); // This crashes.

What version of Builder are you using?

Also FileExists routine does not seem to support wide characters. Is there support for this in later versions.

Starting with the later Builders (2007?) unicode strings had full support. Starting with Builder 2010, unicode strings were the default strings. Anything that AnsiString could do, UnicodeStrings can do. Routines and components like FileExists now default to unicode strings.

I suspect a bug in BCB 6 with wide strings but I'm trying to find out.

This seems to work..

wcscpy(s,aW.Copy());

Oddly enough, I was just about to suggest that.
