Listbox maximum?

[MallardsReach]

How do I restrict a Listbox to 4 entries? Thanks for looking. Solved, found this Listbox1.Items.Count

The ListBox doesn't support such limitations. You'd have to create your own ListBox and add that functionality.

Simple; add a post-it to the monitor that says "don't add more than four in THE listbox". Download the UX-guide from MS (its free) and read why you are using the wrong control, and which one you should be using instead. I'll bet it will point out checkboxes.

It may not be supported but using this

If LstMat1.Items.Count = 4 Then

it did what I required.

Tried adding post-it note to monitor but it still didn't work? Just to recap:-- I need 5 Listboxes one Main Listbox (MLB) and four others LB1, LB2, LB3 and LB4. After entering names in a Textbox and pressing enter the first name goes in to LB1 so does the 2 name, the 3rd and the 4th. The 5th name goes in to LB2 so does name 6, 7 and 8. LB3 gets the next 4 and LB4 gets the next four. Any other names that get entered go in to MLB. Under each LB is a button and when pressed the four names in that LB get added to the bottom of the MLB and the top 4 names in the MLB go in to LB1, 2, 3 or 4 depending on which button under which LB was pressed. Despite all the help and advice offered I have this working exactly as I want with no errors. So it shows, that sometimes, the best help is when your help yourself. And if it still proves difficult then visit a site that offers constructive help and advice.

Seriously, I thought you were writing this for other developers to use. Of course, it's that easy if you're the only one doing this for a single ListBox. If you're looking to reuse this in multiple places, you'd have to make your own version of the ListBox.

My advice remains unchanged, as well as the verdict, as non-typical use of common controls is confusing to typical end-users.

Hi Dave, I only ever code for myself, it's a hobby nothing more, this program is for the bowling club that I attend on Wednesday nights, we have 4 mats and when your game is finished the names of the 4 players go back in to the pool and the next 4 players use the mat you've just left. Below is the complete code, not that you need it but you can see what I did, no comments as it's only for me to play with.

Public Class Form1

Private Sub TextBox1\_KeyDown(sender As Object, e As KeyEventArgs) Handles TextBox1.KeyDown
    If e.KeyCode = Keys.Enter Then
        Static Fillup = 1
        Select Case Fillup
            Case 1
                LstMat1.Items.Add(TextBox1.Text)
                TextBox1.Text = String.Empty
                If LstMat1.Items.Count = 4 Then
                    Fillup = 2
                End If
            Case 2
                LstMat2.Items.Add(TextBox1.Text)
                TextBox1.Text = String.Empty
                If LstMat2.Items.Count = 4 Then
                    Fillup = 3
                End If
            Case 3
                LstMat3.Items.Add(TextBox1.Text)
                TextBox1.Text = String.Empty
                If LstMat3.Items.Count = 4 Then
                    Fillup = 4
                End If
            Case 4
                LstMat4.Items.Add(TextBox1.Text)
                TextBox1.Text = String.Empty
                If LstMat4.Items.Count = 4 Then
                    Fillup = 5
                End If
            Case 5
                LstNames.Items.Add(TextBox1.Text)
                TextBox1.Text = String.Empty
        End Select
    End If
End Sub

Private Sub BtnMat1\_Click(sender As Object, e As EventArgs) Handles BtnMat1.Click
    Static num = 3
    For clearLb = 0 To 3
        LstNames.Items.Add(LstMat1.Items(num))
        LstMat1.Items.Remove(LstMat1.Items(num))
        num = num - 1
        If num = -1 Then
            For fillLb = 0 To 3
                LstMat1.Items.Insert(0, LstNames.Items(0))
                LstNames.Items.Remove(LstNames.Items(0))
                num = 3
            Next
        End If
    Next
End Sub

Private Sub BtnMat2\_Click(sender As Object, e As EventArgs) Handles BtnMat2.Click
    Static num = 3
    For clearLb = 0 To 3
        LstNames.Items.Add(LstMa

That's good to hear then, as I'm the only end user!

Haha, in that case your helpdesk will be prepared for any questions from the users, and no problems handling complaints :D

Eddy, you can always make me smile. :-D May not always understand the advice but always get the humour. (English Spelling)

A gentle suggestion... Even though you are the only user, I still advise you to rename your textboxes to more meaningful names than the default TextBox1 - get into good habits :)
