Hi All,

I’m sorry if this has already been covered.

I’m trying to use iterator_range with a wchar_t.

My code is as follows:

std::wstring buttonName =L"jar:file:/C:/Program%20Files/diseMP/4.5.6/O2-LIVE/lib/client/ClientResources.jar!/branding/default/buttons/FindButtonActive.png";

bool isGraphical =false;

       isGraphical =boost::algorithm::starts_with(buttonName, L"jar:file:/") && boost::algorithm::ends_with(buttonName, L".png");

       boost::iterator_range<wchar_t> range =boost::algorithm::find_last(buttonName, L"/");

I’m getting the following errors:

Does anyone have any clues as to why this is happening or alternatively any working example?

Help appreciated as always.
