Here is some code for VB6 (wordwrapping) 
Private Sub Command1_Click()

'text box's Multiline property to True, and use the
'following code:
'-- VB functions that take strings as parameters
'will not accept a Text property.

'-- Get the formatted text (45 characters wide)
Wrapped$ = WordWrap$(T$, 45)
'-- Save the text to a file.
Open "yourfile.text" For append As 1
Print #1, Wrapped$
Close #1
End Sub
Private Function WordWrap$(St$, Length)
'-- This function converts raw text into CRLF delimited lines.
Length = Length + 1
