Hello, I know this is the fastest way to search a large file but how do I display the lines that I am searching for? Thanks!

Code: 
const ForReading = 1
const TristateFalse = 0
dim strSearchThis
dim objFS
dim objFile
dim objTS
set objFS = Server.CreateObject("Scripting.FileSystemObject")
set objFile = objFS.GetFile(Server.MapPath("myfile.txt"))
set objTS = objFile.OpenAsTextStream(ForReading, TristateFalse)

strSearchThis = objTS.Read(objFile.Size)

if instr(strSearchThis, "keyword") > 0 then
    Response.Write "Found it!"
end if
 
Sort by date Sort by votes
...
Set objTS = objFile.OpenAsTextStream(ForReading, TristateFalse)
While Not objTS.AtEndOfStream
strSearchThis = objTS.ReadLine
If InStr(strSearchThis, "keyword") > 0 Then
Response.Write strSearchThis
End If
WEnd
objTS.Close

Hope This Helps, PH.

instead of reading byte method, read one line at a time. then use the same method of instr to scan each_line for the keyword. if > 0 then msgbox the whole line.
is this what you want?

Or a direct response to the setting the question presumes.
[tt]
'etc etc
strSearchThis = objTS.Read(objFile.Size)

set rx=new regexp
with rx
.global=true
.multiline=true
.pattern="^.*?" & keyword & ".*?$" 'supposing keyword is well-behave, else do some escaping
.ignorecase=true 'or false, depends on need
end with

set cm=rx.execute(s)
if cm.count<>0 then
for i=0 to cm.count-1
response.write "[" & i & "] " & cm(i) & "<br />"
next
else
response.write "no match" & "<br />"
end if
[/tt]

The corresponding line should be read like this.
[tt] set cm=rx.execute([blue]strSearchThis[/blue])[/tt]

Thanks everyone. Here is how I decided to do it and it works great. If you see something wrong with this please let me know. It seems to work great. Also...if anyone can tell me how to search for more than one keyword I would very much appreciate it. Thanks again!

I don't think you've made a good decision, even the worse amongst proposed. It is sure up to you.

Okay...so my way is slower than your suggestion? From what I read on the 4guysfromrolla it seemed as though this was a faster way.

Let me ask this about the suggestions. Are you talking about the way I use the Shell cmd to search and create a new file or are you talking about the parsing of the new file that I create on where I made the wrong decision? Do you think I should even use the shell method or just use vbscript to find what I need? It seemed as though using the find command was faster and since the bp2000.log is constantly being written to I thought it might cause more issues.

I appreciate your help and thank you.

I don't think of slower or faster. I consider dependency. You are working on a server environment and that's how I rate priority notwithstanding the speed is important. Just an opinion, and I have nothing to insist.

I'll give it a try and see which one will work best for what I need it to do. Thanks again.
