Textbox editing...

Ketta · Nov 7, 2003

I know how to read a file system object and output it to the browser page.
The desired result would be to put that file into a textbox on the screen
for a user to modify and then write the file back to the file system. The
concept seems simple enough, read the text file into a variable then some
magic asp will put it into a textbox value, then somehow take that value and
write the file. I know how to write files to the system as well. I am
missing a key piece.. any ideas?

Thanks,
Ketta

Alright, you have the file in a textbox already, so once the user submits
the file, take the request.form("thatTextbox"), create an FSO object, and
overwrite the existing file with the contents from that textbox.

Well thanks for that part, that will definately help me. But I still do not
have the file in a textbox. It just outputs it to the screen. This is my
code for reading the file and putting it on the screen. I'm a total noob
with ASP btw. This is probably just annoying to have someone like me asking
for help. Now all I need is the code below to output to a textbox....
somehow.

<%
set fso = server.createobject("Scripting.FileSystemObject")
set fs = fso.openTextFile("textfile.txt",1,true)
response.write replace(replace(fs.readall,"<","<"),vbCrLf,"<br>")
fs.close: set fs = nothing: set fso = nothing
%>

Thank you

If I were annoyed, I wouldn't use newsgroups. :]

You can just server.execute the contents of the file, i.e.

http://yoursite/filemod.asp?filename=file.txt :
<%
sFilename = Request.Querystring("filename")
%>

<html>
<form method="post" action="filemodp.asp">
<input name="filename" value="<%=sFilename%>" type="hidden">
<textarea name="fileContents" style="width: 500px; height: 800px;"><%
Server.Execute sFilename %></textarea>
<input type="submit">
</form>

http://yoursite/filemodp.asp :
<%
Dim sFilename, sContents
sFilename = Request.Form("filename")
sContents = Request.Form("fileContents")
If sFilename <> "" Then
Set oFSO = Server.CreateObject("Scripting.FileSystemObject")
Set oFile = oFSO.CreateTextFile(Server.MapPath(sFilename), True)
oFile.Write sContents
oFile.Close
Set oFile = Nothing
Set oFSO = Nothing
End If

Response.Redirect "filemod.asp?filename=" & sFilename
%>

Play around with that to see what I mean. But, what you'll want to do first
is create a file named "file.txt" throw a few characters into it, and then
load up the filemod.asp page with the ?filename=file.txt querystring. This
sample has no handling of errors for empty or non-existant files.

Wrap the file content in textarea tags like so:

<%
set fso = server.createobject("Scripting.FileSystemObject")
set fs = fso.openTextFile("textfile.txt",1,true)
Response.Write "<textarea name='myTextArea' cols='80' rows='10'>"
Response.Write fs.readall
Response.Write "</textarea>"
fs.close: set fs = nothing: set fso = nothing
%>

P.S. Your question was not annoying and you don't need to apologize for
being new to ASP. Everyone was once.

Hope to hear from you again.

http://yoursite/filemod.asp?filename=file.txt :
<%
sFilename = Request.Querystring("filename")

<html>
<form method="post" action="filemodp.asp">
<input name="filename" value="<%=sFilename%>" type="hidden">
<textarea name="fileContents" style="width: 500px; height: 800px;"><%
Server.Execute sFilename %></textarea>
<input type="submit">
</form>

This introduces a significant security hole in the system since it
allows the end user to post/execute code of their choosing. I would
stick with using the FSO.

That is quite true.
