Search text file and put matching results in listbox

I have a VB.NET project in which there is a form where there is a TextBox control, a ListBox control and an external text file that contains a list of outlook folder paths for client emails.
Essentially, the user enters into the text box the name of a client and/or their unique reference number, presses the search button (yes - I know I could make the results appear as they type, I want a button!) and it comes up with the matching results for the company name or serial number that are in the text file and puts them in the list box, with the full path of the outlook email folder.
For example:
If I put into the textbox: "06967759-274D-40B2-A3EB-D7F9E73727D7"
It would put the following result into the listbox:
"EIS Admin\Contacts{06967759-274D-40B2-A3EB-D7F9E73727D7}"
And the user can then go to that folder and find the email(s).
I have gone through several revisions both of my own code and code pasted from online with people having the same issue, only to have Visual Studio throw no errors, run the code and have no luck, with it doing nothing but clearing the list box, and not showing matching results of any kind.
I understand this may be a repeat question but I am extremely confused, can't get anything to work and need some help regarding my issue.
Here is the current code (from online - not mine):
lbx_OFL_Results.Items.Clear()
Dim i As Integer
For i = 0 To lbx_OFL_Results.Items.Count - 1
If i > lbx_OFL_Results.Items.Count - 1 Then Exit For
If Not lbx_OFL_Results.Items(i).Contains(tbx_FindText.Text) Then
lbx_OFL_Results.Items.Remove(lbx_OFL_Results.Items(i))
i -= 1
End If
Next
The list box is called "lbx_OFL_Results"
The textbox is called "tbx_FindText"
I start by clearing the list box of all items (when the form loads, it fills the list box will all lines of the text file, so I need to clear it).
Form Load Event Code:
Dim lines1() As String = IO.File.ReadAllLines("C:\ProgramData\WPSECHELPER\.data\Outlook Folder Wizard\outlookfolders.txt")
lbx_OFL_Results.Items.AddRange(lines1)
For the rest of the code it seems to be doing some form of a 'sort search' then removing any excess results.
If anyone can suggest edits to my code, or new code then that would be sublime.
Thanks.
Thanks to #Jimi for the answer.
Code:
listbox.Items.Clear()
listbox.BeginUpdate()
For i as Integer = 0 To lines1().Length - 1
If lines1(i).Contains(searchbox.Text) Then
listbox.Items.Add(lines1(i))
End If
Next
listbox.EndUpdate()
I have another question which solves how to make this search non case-sensitive. It can be found here.

Show Data Grid View specified cell value in Textbox

I am a student programmer who is learning VB. I am trying to make a telephone book type project in VB (Windows Forms). In my project I am using an unbound Data Grid View control. Below the Data Grid View, I have some textboxes which will display the values of the selected row. On the form load event, my program accesses a file and populates the Data Grid View control with values from the file. This works perfectly, but the problem I get is when I use the code:
txtLast.Text = dgvMain.Rows.Item(0).Cells(0).Value
to populate the textbox called txtLast with the value at the specified cell, the textbox doesn't display the value. The program doesn't crash or hang, it simply won't display the value and when I try to edit the textbox, it acts as if the textbox is empty. I have tried using
txtLast.Text = dgvMain.Rows.Item(0).Cells(0).Value.ToString()
as well as trying to refresh my Data Grid View control and the textbox. Nothing has worked so far. When I use a breakpoint to see whether that line of code is executed, the autos window shows me that the line of code is executed and that it sees the value of the specified cell as "Smith". However, when I press F11 to step into the next line, the textbox.text property remains as "" instead of changing to "Smith".
Note: when I manually specify the text through the code (i.e. txtLast.Text = "Test") it will show that text. Also, this problem is not with just one textbox, it is with every textbox that I use (I have 5 textboxes showing various values from the specified row). The weird thing is that out of the 5 textboxes, one of them, the masked textbox which shows the phone number works perfectly with the same line of code. (note it is not a problem only affecting regular textboxes as I have tried using both regular textboxes and masked textboxes, both produce the same problem except for the phone textbox).
Also, I would prefer to keep the Data grid view unbound (not connected to a database) and the textboxes unbound (not connected to the data grid view as a data source) because while browsing the internet I have seen people suggesting to bind the textbox or data grid view, however I do not understand how to do so, and I believe that this can be done without binding to a data source.
Any help is appreciated in trying to figure out why the text doesn't change. Let me know if you need any other info or if part of my explanation is unclear.
Thanks!

Make a form with a textbox, combo box, and a second textbox.
Add a command button to save the data, one to show data, and possibly one to cancel and one to exit.
Fill the combobox with the appropriate items.
In the click handler for the save button, write the data to a file with "append".
The show data button can read the file display the text in a multiline text box or rich text box.

I wish to edit the text at run time but

VB in Access: Combo Box Values are not visible in form view but are visible through Debug.Print

Code in Form onLoad:
country_combo.RowSourceType = "Value List"
Code in a reset function:
Dim lListIndex As Long
With Me.country_combo
For lListIndex = .ListCount - 1 To 0 Step -1
.RemoveItem (lListIndex)
Next lListIndex<br/>
End With
Code to populate country combo:
*For n = 1 To numCountries*
*countryCombo.AddItem (countryRS.Fields("countryName"))*
*countryRS.MoveNext*
*Next n*
I'm having a problem that occurs AFTER the code to populate the country combobox runs. The values are there as I can run Debug.Print(countryCombo.Value) and it prints out the name of the selected country, but I can't see the values in the combobox at all. They're invisible, and as far as I know there is no visiblity property for specific items, unless I'm completely mistaken.

I think you should probably use Access's GUI tools to do what you're looking for. In design mode, click on the field you are trying to populate, then click the "lookup" tab. You can then specify a table to populate the field with and your forms should automaticly update as well.
I've also seen what you describe here - as far as I can tell, it's a bug within Access (I was using 2007) that only occurs when you programatically mess with the contents of a combo box. It does not happen every time. The issue corrects itself if you highlight the text that is in the combo box.
I am experiencing a similar issue with Access 2003. Based on the selection of one combo box, the row source of a listbox is set to an SQL string Basically a SELECT DISTINCT [MyField_Selected] FROM MyTable. For some fields the values are visible in the list box and others it is not. The values are there however as I can access them via code. To make it more interesting it works fine in Access 2007.
Just found the resolution on another forum. Check the format property of the field(s) in question on the table. In my case, when Access 2007 created the table, it put an # format in there. I removed that and all works great!
