[RESOLVED] Help with list box items and Textbox

I have struggled to find a way to make this work. I have a listbox that has 5 items. These items are lets say Company Name, Address, User Name, Phone, Fax. On the form I also have the same labels with richtextboxes under each of the above names.

What I am looking to do is have each listbox item equal the text that is related to each textbox. Then write to file from the listbox.The file created should be the text from the related textboxes.

The goal is to allow the user to re-arrange the items in the listbox via drag and drop (which I think I have figured out) and write a new order of the file.

Here is my code Code:

Private Sub listBoxCompInfo_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles listBoxCompInfo.SelectedIndexChanged
 
        listBoxCompInfo.SelectedItem(0) = rtbCompName.Text
        listBoxCompInfo.SelectedItem(1) = rtbCompAddr1.Text
        listBoxCompInfo.SelectedItem(1) = rtbCompAddr2.Text
        listBoxCompInfo.SelectedItem(2) = rtbProgrammer.Text
        listBoxCompInfo.SelectedItem(3) = rtbPartNumer.Text
        listBoxCompInfo.SelectedItem(4) = rtbMachineName.Text
        listBoxCompInfo.SelectedItem(5) = rtbComments.Text 
Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSaveSettngs.Click
        Dim ItemArray(Me.listBoxCompInfo.Items.Count - 1) As Object
        Me.listBoxCompInfo.Items.CopyTo(ItemArray, 0)
        Dim Data As String = Join(ItemArray, Environment.NewLine)
        My.Computer.FileSystem.WriteAllText("c:\test.txt", Data, False)
    End Sub

Any Help would be greatly appreciated!

listBoxCompInfo.Items(0) = rtbCompName.Text

Paul,

Thank you for your response. I feel like such an idiot. I did make the change and it does change the listbox item to the text that was input from the textbox. What I was looking for is too not have the listbox item text change but rather make an association to the listbox item and the textbox. Maybe I am going about this all wrong or using the wrong controls. How can I make a listbox item retrieve the string in text box without changing either the listbox item text or the textbox text.

The textboxes are to be input fields for the user to enter information. The listbox items need to be connected to the correct textbox somehow in order for the user to re-arrange the entered information in the listbox. When the user clicks a button that information will be written to the file. As it sits right now only the contents are being written to the file and not the textbox information.

Any ideas?

use custom listItems:

vb Code:

Public Class listItem
 
    Public displayText As String
    Public associatedText As String
 
    Public Overrides Function ToString() As String
        Return Me.displayText 
    End Function
 
    Public Sub New(ByVal display As String, ByVal hidden As String)
        Me.displayText = display 
        Me.associatedText = hidden 
    End Sub
 
End Class

then to add to your listbox:

vb Code:

listbox1.items.add(new listItem("text to show in listbox", "associated text"))

to retrieve your associated text for a listbox entry:

vb Code:

MsgBox(DirectCast(ListBox1.Items(0), listItem).associatedText)

To make it a little more clear below see below.

When the user re-arranges the order the text file is written in that order.

ok. how are you changing the order of the listbox items?

Using drag and drop. The user can change the order at runtime. Here is the code I have. Seems to have a small bug as the listbox items move but on the drop event become invisible.

Code Code:

Private Sub listBoxCompInfo_DragDrop(ByVal sender As Object, ByVal e As System.Windows.Forms.DragEventArgs) Handles listBoxCompInfo.DragDrop
        listBoxCompInfo.Items.Insert(listBoxCompInfo.IndexFromPoint(listBoxCompInfo.PointToClient(New Point(e.X, e.Y))), e.Data.GetData(listBoxCompInfo.Text))
        listBoxCompInfo.Items.RemoveAt(listBoxCompInfo.SelectedIndex)
    End Sub
 
    Private Sub listBoxCompInfo_DragOver(ByVal sender As Object, ByVal e As System.Windows.Forms.DragEventArgs) Handles listBoxCompInfo.DragOver
        e.Effect = DragDropEffects.Move
    End Sub
 
    Private Sub listBoxCompInfo_MouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles listBoxCompInfo.MouseDown
        listBoxCompInfo.DoDragDrop(listBoxCompInfo.Text, DragDropEffects.All)

try this:

Bingo!!!! Paul you are the man!!! This is exactly what I was looking for. Thank you so much. You are might be the listbox king! Thanks again man for all the help I REALLY appreciated it and the example you shared is going to push my knowledge base a ton.

I noticed that this is on the form load event. The controls are in tabpage so can I assume that I can use the tabpage click event instead of form1 load? Or would it be more efficient to create a usercontrol then initiate that component.

i'd go with the usercontrol

That is what I thought. But I am having difficulties initiated the 2 control. The first one works perfect but am not quite sure how to get the second one to initiate.

Code for Custom Tabpage Class Code:

Public Class TabPageEx
    Inherits System.Windows.Forms.TabPage
 
    Private WithEvents uc As New UserControl1
    Private WithEvents uc2 As New UserControl2
 
 
    Public Sub New()
        Me.uc.Margin = New Padding(0)
        Me.uc.Dock = DockStyle.Fill
        Me.Controls.Add(Me.uc)
        Me.UseVisualStyleBackColor = True
        Me.uc2.Margin = New Padding(0)
        Me.uc2.Dock = DockStyle.Fill
        Me.Controls.Add(Me.uc2)
        Me.UseVisualStyleBackColor = True
    End Sub
 
 
    Private Sub InitializeComponent()
 
    End Sub
   
End Class

Here is the button click event that adds the tabpage.

Code Code:

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
 
        Dim Mytab As New TabPageEx
        frmPrefsDialog.TabControl1.TabPages.Add(Mytab)
        Mytab.Text = RichTextBox1.Text
        frmPrefsDialog.TabControl1.SelectedTab = Mytab
 
        Me.Close()
 
    End Sub

Now I am struggle on how to inititiate the second usercontrol still using the TabPageEx Class. Do I need to make another seperate Class Such as TabpageEx2 too handle usercontrol2? The usercontrol2 needs to happen on form load so that the tab is always present. This may be a simply answer and apologize. I truly am trying to learn this at times gets so confusing.


I realized that this should be another topic. Mod please mark this as resolved

Thanks Again
