Hi,
Use this code. This will create a html file with the contents in your text box...
Code:
<%
	Set fso = CreateObject("Scripting.FileSystemObject")
	szContents = Request.form("MyText")
	szFile = "C:/Test.htm"
	If(szContents<>"")then
		fso.OpenTextFile(szFile, 2, True,false).Write szContents
	end if
%>
<form name=MyForm method=post action=try.asp>
	<input name=MyText type=text value="">
	<input type=submit value=Save>
</form>
Get back if u have any issues...
