I'm using a windows edit box and I want to set its text to what I read in from a file, but it does not insert the returns so everything is on one line. example: in the file: hello goodbye in the edit box: hellogoodbye also if I just try setting the text using: SendMessage(hWnd_edit, WM_SETTEXT, 0, (LPARAM)"hello\ngoodbye"); it does not take the \n to mean return(or at least insert one), but \t inserts a tab. the edit box is created using: hWnd_edit =CreateWindowEx(0, "EDIT", "edit", ES_MULTILINE | ES_AUTOVSCROLL,600, 0,400,400,0,NULL,hInstance,NULL); any ideas on how to insert a return?

The Windows edit box ignores new lines on their own. You may need to insert a carraige return/line feed pair. Basically, you need to include a \r as well.

There are a few reasons why Windows may be jerking you around, but I have certainly come across this one before. It's the root cause as to why Notepad can't hack Linux or Mac formatted text files.

On Windows, the character sequence \r\n is a hard line break. So, change this string

"hello\ngoodbye"

to this

"hello\r\ngoodbye"
