C++ (Korean) insert error (Incorrect string value) - c++

Question

DB is a C ++ in conjunction with student card management program.
Enter your information to receive a student receives a first input your name and ID. The problem is that there is an error in the insert names.
When directly from MS-DOS window insert (visual studio X)
Hangul (korean) is normal.
(Try the workaround that looked out to the Internet.)
when the insert through a C ++, Hangul (Korean) is not.
hakbun int(50) not null primary key,
name char(100) not null
▲ columns of the table, including information
▲ query status
