Thanks for all your relevant answers and wiki updates. I understand the goal is to replace String and its variants by OUString. My last remaining question is "what is the use of OString? Where/when is it used in the application?" Thanks, Jean-Noël <div class="gmail_quote">2013/1/15 Norbert Thiebaud <<a href="mailto:nthiebaud@gmail.com" target="_blank">nthiebaud@gmail.com</a>> <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"> <div class="im">On Tue, Jan 15, 2013 at 12:26 PM, Eike Rathke <<a href="mailto:erack@redhat.com">erack@redhat.com</a>> wrote: > > For example, a > > if (String.Search(...) == STRING_NOTFOUND) > > replaced with > > if (OUString.indexOf(...) == STRING_NOTFOUND) > > will not work. </div>A even more tricky case is this: String's functions usually deal silently with out-of-buffer stituations, like asking to delete a part that overflow or even is entirely outside a string. and Search return as indicated above STRING_NOTFOUND that is 0xffff i.e the max unsigned value of Xub_StrLen so some code use this 'feature' to code something like: pos=String.Search('#') String.Erase(pos) IOW: automated conversion is _not_ an option. String => OUString convertion have to be carefully audited by hand, even if 99% of these are trivial.
