From Format Specification Fields: scanf and wscanf Functions[^] :

An input field is defined as all characters up to the first white-space character (space, tab, or newline), or up to the first character that cannot be converted according to the format specification, or until the field width (if specified) is reached. If there are too many arguments for the given specifications, the extra arguments are evaluated but ignored.

Setting a breakpoint on the MessageBox call would allow you to examine the contents of MyString before it's displayed, where you can see it's already truncated.

A couple additional points. My C is a little rusty, but ..

a) Your 'LPCSTR(MyString)' cast is unnecessary.
b) It's not a cast, but rather (I believe) an invocation of a LPCSTR constructor with MyString as a parameter. You're not executing a cast, you're creating a new null-terminated string pointer, pointed at MyString.
c) A cast would have been '(LPCSTR)MyString'. But like I said, it isn't required here.
