From: Derek on 15 Feb 2006 13:15 CString sHexBgColor; string Str = (LPCTSTR)m_sHexBgColor; The plan is to use it with this method: ConvertColor(string color); "Ajay Kalra" <ajaykalra(a)yahoo.com> wrote in message news:1140027010.407000.103470(a)g43g2000cwa.googlegroups.com... > Can you show the code which is causing this error? > > --------- > Ajay Kalra > ajaykalra(a)yahoo.com >
From: Derek on 15 Feb 2006 13:22 David, sorry I miss your reply. Your solution works! typedef std::basic_string<TCHAR> tstring; CString Temp = _T("This is a test"); tstring Str = (LPCTSTR)Temp; Thanks a lot!

From: Ajay Kalra on 15 Feb 2006 13:29 This will not work for UNICODE as expected. As pointed out earlier, you should not be using string, use tstring/wstring instead. -------- Ajay Kalra ajaykalra(a)yahoo.com
From: Derek on 15 Feb 2006 13:38 Yes, I noticed that. I compile now, but at runtime getting: C++ exception: std::out_of_range @ 0x0013c7d8. thanks "Ajay Kalra" <ajaykalra(a)yahoo.com> wrote in message news:1140028161.735387.273220(a)g44g2000cwa.googlegroups.com... > This will not work for UNICODE as expected.
