Why do some guest books do not need a database? _ Programming 10000 Q

< html>

< body>

< form action= "manage.asp" method= "POST" >

< input type= "text" size= "ten" name= "username" >

< input type= "text" size= "ten" Name= "homepage" >

< input type= "text" size= "ten" Name= "Email" >

</form>

</body>

Manage.asp

<%

StrName = Request.Form ("username")

Strhomepage = Request.Form ("homepage")

Stremail = Request.Form ("Email")

' get form information .

Set FSO = Server.CreateObject ("Scripting.FileSystemObject")

' Create an FSO object .

Path = "C:chunfeng/form.txt"

ForReading = 1, ForWriting = 2, ForAppending = 3

Set file = Fso.opentextfile (path, ForAppending, TrUE)

'Open File. OpenTextFilemethod returns aTextStreamObject,This object reveals how to manipulate the contents of a file, and we're still in opentextfiletrue,,,true parameter , system will be wrong

File.write (strName) & vbCrLf

' VB constant vbCrLf produces a newline character .

File.write (strhomepage) & vbCrLf

File.write (stremail) & vbCrLf

' write information to the file .

File.close

Set file = Nothing

Set fso = Nothing

' empty .

Now open form.txt, you can see the following information:

User ' s name

User ' s home page

User ' s Email

　　

1 2< Span Times New Roman '; Mso-hansi-font-family: ' Times mso-bidi-font-size:9.0pt ' is the user homepage, the first 33fso
<%
Set fso = Server.CreateObject ("Scripting.FileSystemObject")

' Create an FSO object .
Path = "C:chunfeng/form.txt"

Set file = Fso.opentextfile (path, 1)

' open the file .

Do until file. AtEndOfStream

' Atendofstream is textstream Attributes of the object , It prompts when to file tail         Response.Write ("Name:" & file.) ReadLine & "")

' Readline method reads 1 The content , Until the line break is encountered , then readline Call reads the next line         Response.Write ("Home Page:" & file.) ReadLine & "")
        Response.Write ("Email:" & file. ReadLine & "< p>")

' parse and format the data line by row .
Loop
' loop through each user's information .
File.close
Set file = Nothing
Set fso = Nothing
%>

It's all done.

If the form.txt itself has errors , such as the fact that each user 's information is only 2 lines instead of 3, the following error message is generated:
　　Server object error ' ASP 0177:800a003e '
