Hello everyone!

I'm a newbie who is from Vietnam (so I'm not good at English)!

I have a problem in VB.NET.
As far as we have known, VB's supported control array, but VB.NET isn't supported.

I've designed a lot of buttons (100 button) on a form.
Then I've set names for them are Button1, Button2,...Button100.

I'd like to create an array to contain this Buttons (Button1,..Button100 that I have designed on the form)-(NOT CREATE AN ARRAY TO CONTAIN NEW BUTTONS).

So, How can I do it? please show me a way!

help me please! :confused:

After your clarification, I would suggest to use following code. You don't need array to do that.

VB

'Dim buttons() As Button


For i = 1 To 100
  Dim btns() As Button = Controls.Find("Button" & i, True)
  Dim btn As Button
  If btns IsNot Nothing Then
    btn = btns(0)
    'If buttons Is Nothing Then
    '  ReDim buttons(0)
    'Else
    '  ReDim Preserve buttons(buttons.Length)
    'End If
    'buttons(UBound(buttons)) = btn
    btn.Text = i - 1 'here you can change whatever you want
  End If
Next

Step 1, Create a Form called Form1.
Step 2, Add a TableLayoutPanel called TableLayoutPanel1.
Step 3, Make it 10 X 10 with 10% each.
Step 4, Set its anchor to T, B, L, and R. (It could be in any size in design time)
Step 5, Copy the code to Form1.vb.
Step 6, Run it, and you get it.
Step 7, If it works for you, please mark this one as 5.00. I wish to get 10 * 5.00 in 3 days.

Public Class Form1
    'Use 0 based array
    Private NRow As Integer = 9
    Private NCol As Integer = 9
    Private BtnArray((NRow + 1) * (NCol + 1) - 1) As Button
    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        TableLayoutPanel1.Size = Me.ClientSize
        For i As Integer = 0 To BtnArray.Length - 1
            BtnArray(i) = New Button()
            BtnArray(i).Anchor = AnchorStyles.Top Or AnchorStyles.Bottom Or AnchorStyles.Left Or AnchorStyles.Right
            BtnArray(i).Text = CStr(i)
            TableLayoutPanel1.Controls.Add(BtnArray(i), i Mod (NCol + 1), i \ (NCol + 1))
            AddHandler BtnArray(i).Click, AddressOf ClickHandler
        Next
    End Sub
    Public Sub ClickHandler(ByVal sender As Object, ByVal e As _
   System.EventArgs)
        MsgBox("I am button #" & CType(sender, Button).Text)
    End Sub
End Class

Solution 2

VB

Dim buttons() As Button


buttons = Nothing
For Each b As Button In Me.Controls
  If buttons Is Nothing Then
    ReDim buttons(0)
  Else
    ReDim Preserve buttons(buttons.Length)
  End If
  buttons(UBound(buttons)) = b
Next

buttons will be your array.
By the way, why you need the array?

Thank you so much! I'm glad when u write to me! I have an application in VB.NET, It's about the numbers, The Text of each button is a number which from 0 to 99. I'd like to use the For...Next loop to add number which from 0 to 99 on the text of each button of button array. But, as u know, I don't know how to create an array to contain my buttons without creating new buttons. Do you actually understand me?

Solution 1

Try:

Dim buttons As Button() = New Button() {Button1, Button2, Button3}

BTW: Life is a lot easier to work with when you don't call things "Button1" and "Button2" but "butChangeName", "butChangeTown" and so forth: What does "Button76" actually do? Without looking in your code?

Solution 3

hey,
to creat controls dynamically we must deside were we create perticular control.

for your question.
declare following statement in new or in formLoad menthod

Dim temp As Label()

which assign memory for array of controls.

Dim h as integer
Dim i as integer
for i=0 to 10                                     'for 10 labels. this value can varies accordingly
  temp(i) = New Label
  temp(i).Top = 10+h
  temp(i).Left = 10
  temp(i).Width =60
  temp(i).Height =20
  temp(i).TextAlign = HorizontalAlignment.Right 
  temp(i).Text = "this is label"


  Me.Controls.Add(temp(i))
   h= h+ 65

Thanks for help me! but I'm sorry, I don't actually know what you mean! can you show me the detail of them! please!

Hey dear,
you want details on above code and you want to create button instead of label plese goes with following code.

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim temp As Button()
Dim h as integer
Dim i as integer
for i=0 to 100 'for 10 labels. this value can varies accordingly
temp(i) = New Button
temp(i).Top = 10+h
temp(i).Left = 10
temp(i).Width =60
temp(i).Height =20
temp(i).TextAlign = HorizontalAlignment.Right
temp(i).Text = "this is button"+Convert.ToString(i)

Me.Controls.Add(temp(i))
h= h+ 65

End Sub

this will work fine
