• jerry1 C++/CLI language design questions

What happens is, it works when I set the project to use Multi-byte libraries and fails when I set it to unicode(no infotip appears). In both cases, LVN_GETINFOTIP is called. Assuming that it's probably a bug in WTL or in the listview infotip implementation, I tried manually using tooltips in WinAPI.... Here's ...Show All
