Insert Newline with Writefile

Hi,
I need to insert newline at the end of a textfile using writefile.
Is this possible or are there another API-Call to do that?

/John Jacobson

WriteFile hFile, xxx, 10, numwritten, CLng(0)

Have you tried substituting xxx above for one of these :
vbcrlf
Chr(13)

Try vbCrLf or vbNewline

That didn't work.
I Solved the problem with the VB scripting Runtime instead, It's a bit slower, but it works.
