syncing tabpages to listview lines

[shadowfyre]

Some of you may remember that I wrote a program that read in a bunch of lines from a text file, parsed the data on each line, and displayed the results on tab pages, one tab page per line of data. It went something like this:

File:

Line1 yaddayaddayadda
Line2 blahblahblah
Line3 spamspamspamspam

Then the program would make 3 tab pages and list the data like this:

Tabpage1:

HEADER   Line1
ELEMENT1 yadda
ELEMENT2 yadda
ELEMENT3 yadda

Tabpage2:

HEADER   Line2
ELEMENT1 blah
ELEMENT2 blah
ELEMENT3 blah

Tabpage3:

HEADER   Line3
ELEMENT1 spam
ELEMENT2 spam
ELEMENT3 spam
ELEMENT4 spam

What I would like to do is take each line of data and put it in a listview, then as a tabpage is selected, the corresponding line in the listview would get highlighted. So if I am looking at Tabpage 3, then Line3 would be highlighted.

My problem is that I don't quite know where to begin. Building the listview would not be a big deal. I have to read each line in to parse it anyway, it would only take a line or two of code to throw it in a listview.

My main question is where would I put the code that detects which tab page is selected and highlights the line in the listview? Would this be in the tabcontrol, or what?

BUMP!

Please someone? I'm still at a loss here.

Alright.

So I figured most of this out. My program adds tabpages dynamically because I never know how many lines an input file will have. What I did with that is I added an index counter (tpindex) to assign a tabindex to each tabpage.

TmpTabPage.TabIndex = tpindex

Also, I throw the string read in from the input file (InputStr) into a listbox on form 2 which I declared in a module. As above I assinged it an index (lbindex). In retrospect, I probably should have used tpindex instead.

Frm2.ListBox1.Items.Add(InputStr)
Frm2.ListBox1.SelectedIndex = lbindex

Then I added this to detect when the selected tabpage changes. (lbflag is a flag that prevents this code from running until the input file has been loaded into the application, otherwise it has problems)

Private Sub TabControl1_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TabControl1.SelectedIndexChanged
        If lbflag = 1 Then
            Frm2.ListBox1.SelectedIndex = Me.TabControl1.SelectedIndex
        End If
End Sub

I had planned on swapping the line

Frm2.ListBox1.SelectedIndex = Me.TabControl1.SelectedIndex

for use with the listbox. (I want to be able to click on the listbox and the corresponding tabpage would be selected) but I couldn't figure out how to reference form 1. Any Ideas?
