[RESOLVED] Parsing/Copying Strings

[mbutler755]

I built a helpdesk version of a program that would parse out certain information. Now, I am trying to automate it using the same code under a load event and I just can't get it to work. The original code was worked on by .paul. and he did a great job! The original forum is located here.

My Code:

Imports System.Text
Imports Microsoft.VisualBasic.FileIO
Imports System.Collections.ObjectModel
 
 
Public Class SecurityParser
 
    Private Sub SecurityParser_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
 
        ' Fill textbox1 with the original DEBOUT.TXT
        '
        Dim DeboutTXT As String = My.Settings.DeboutLocation
        Dim fileContents As String
        fileContents = My.Computer.FileSystem.ReadAllText(DeboutTXT)
        TextBox1.Text = fileContents
 
        ' Search the contents of the textbox for the keywords
        '
        Dim lines As New List(Of String)(IO.File.ReadAllLines(DeboutTXT))
        Dim matches = (From line In lines Where line.contains("Login") Or line.contains("Username") _
                     Or line.contains("Logout") Or line.contians("rpt") Or line.contains("USERNAME") _
                     Select "LINE " & lines.IndexOf(line) & ": " & line).toarray
 
        If matches Is Nothing OrElse matches.length = 0 Then MsgBox("Nothing found") : Return
        TextBox2.Lines = matches
 
        ' Create the audited file, will be moved by the form1.load event in the background worker
        '
        My.Computer.FileSystem.WriteAllText(My.Settings.XFER_Dir & "AM-AUDIT.TXT", TextBox2.Text, False)
 
    End Sub
End Class

I am getting one error, which is:

Error	1	Expression of type 'System.Collections.Generic.List(Of String)' is not queryable. Make sure you are not missing an assembly reference and/or namespace import for the LINQ provider.	C:\Documents and Settings\mbutler\My Documents\Visual Studio 2008\Projects\Briad Backup\Briad Backup\SecurityParser.vb	20	37	Briad Backup

I did not need to call any references for the other program and I am just wondering if I am missing something. Any help is much appreciated.

Ignore, I got that wrong

if vs says it needs a reference, it won't work without it.
some references are added as default depending on the target framework + if you compare references in the 2 projects you'll probably see the problem

.paul.,

I have checked all the references. I had to change the default framework from 3.0 to 3.5. I now match the other program, but the issue persists. I have attached an image.

Old References -> References from the other program
New References -> References on the new program

Just to be sure, don't you need to Import System.LINQ in order to perform Queries on your objects ?
I saw you have System.XML.Linq in your references but... I don't know... I always import it to be sure.

LINQ is part of the 3.5FW... so it won't work against the 3.0FW.

you're missing a system.core reference there too

I do not have a System.LINQ reference available. It goes straight from System.IO.Log to System.Management. Why would the other program work without this reference if it were required?

[mbutler755]

Adding System.Core could not be added. This component is already automatically referenced by the build system.

[mbutler755]

Interesting. I added the reference to System.LINQ to the page itself:

Imports System.Linq

And it works now. Thanks stlaural!

Edit : Took me too long to write my answer, you already solved your problem !

As techgnome said :

Are you sure you are using Framework 3.5 ?
1- to check select Project menu
2- at the bottom should be "Your Project Name" Properties..., Select it
3- in the Compile tab click on the button "Advanced Compile Options..."
4- At the bottom of the newly opened window there is a dropdown titled "Target framework"
Make sure .NET framework 2.5 is selected.

Then you should have access to the library System.LINQ
