How to get a "click" in an component created at runtime ?

Hi, guys!

I'm in trouble with it...

I created an array of command buttons (for instance), at runtime, and I need to know which was clicked...

But when I click anyone I have no answer...

What's going on ?

Follows the code where I create the array of command Buttons:

VB Code:

Option Explicit
Dim lbl(4) As Label
 
Private Sub lbl1_Click()
    MsgBox chkbox.Name
End Sub
 
 
 
Private Sub Form_Load()
    Dim x As Byte
 
    For x = 0 To 4
    
    Set lbl(x) = Me.Controls.Add("VB.Label", "lbl" & Me.Controls.Count) '& "(" & x - 1 & ")")
    With lbl(x)
            .Left = 1000
            .Top = 500 * x
            .Width = 2000
            .Height = 500
            .Caption = lbl(x).Name
            .Visible = True
    End With
    Next x
End Sub
    
     
     
    Private Sub Form_Unload(Cancel As Integer)
     
        Dim i As Integer
 
        For i = 0 To 4
            Set lbl(i) = Nothing
        Next i
         
    End Sub

tks!

You won't be able to. You can acchive that only with single control (not a control array) with the WithEvents:

VB Code:

Option Explicit
    Private [B]WithEvents[/B] cmd As CommandButton
 
Private Sub Form_Load()
    Set cmd = Me.Controls.Add("VB.CommandButton", "cmd")
        With cmd
            .Caption = "Click me!"
            .Visible = True
        End With
End Sub
 
Private Sub cmd_Click()
    MsgBox "You clicked me!"
End Sub

If you want to have a control array then add one CommandButton at design time and change it's .Index property to 0. Then try this:

VB Code:

Option Explicit
 
Private Sub Form_Load()
    Command1(Command1.ubound).Caption = Command1.ubound
    loadCommandButtons [B]2[/B] 'will add 2 new CommandButtons...
End Sub
 
Private Sub loadCommandButtons(n As Integer)
    For n = 1 To n
        Load Command1(Command1.ubound + 1)
            With Command1(Command1.ubound)
                .Move Command1(Command1.ubound - 1).Left, Command1(Command1.ubound - 1).Top + Command1(Command1.ubound - 1).Height + 100, Command1(Command1.ubound - 1).Width, Command1(Command1.ubound - 1).Height
                .Visible = True
                .Caption = Command1.ubound
            End With
    Next n
End Sub
 
Private Sub Command1_Click(Index As Integer)
    MsgBox Index
End Sub

Gavio,

Thanks your fast answer...

I tried the both ways you said...

My problem is:

If I use "WithEvents" I can't:
- create an array...
- change the component's name...

If I use "Set" I must to create a lot of controls, cos I have a "crazy" system, where I need to make severous arrays of controls...

Such this:

Label (0)
Label1 (0) check1(0)
Label1 (1) check1(1)
Label1 (2) check1(2)

Label (1)
Label2 (0) check2(0)
Label2 (1) check2(1)
Label2 (2) check2(2)

And I have no Idea how many label(X), Labelx(x) and checkx(x) I'll need at each time...

Jlarini,

I decided to cheat when I needed an array of command buttons by creating a command button at design time that was visible=false and using that command button to make copies of.
Two major benefits for me to using this method were:
firstly I had multiple copies of the command buttons click event and second It was of great benefit to me to have the first usable button in my array numbered as 1.
