How to limit the number of the character in each line in a richeditctrl

[lugangxyz]

I use a richedit in my dialog,when i use streamin() put some text in it ,some lines is very long that the user must use the hscroll bar to view it,is there any method to limit each line's text number?

Take a look at SetMargins

void SetMargins( UINT nLeft, UINT nRight );
