Problem With Dynamic Loded Control Array
I am facing one Problem because of Limitaion of VB ..but i am some how hope that
there is solution of this problem
In my programme i am creating some control at run time on form in that there is one frame
and inside that frame three is label conrolarray. Frame is container of Lable controlArray
now i want to catch the event such like click of lable control .. as i write here before label conrol
is in control array..
problem with event not support controlarray that i have idea but may be it is possible
through VBControlExtender and use of Collection
if you see this example
https://www.experts-exchange.com/questions/10303725/Array-of-Private-WithEvents-controls-How.html
in that there is same type of qustion but the solution is based on UserControl but i am not
work with usercontrol.
this is my code below in this i did for only one control but actually i need that type of
event which fire each time when one of the control from control array is operated..
add one Form , One Module , One Class
## Form1 ##
Private Sub Form_Load()
Call makecon
End Sub
## Module1 ##
Public ctlFrame As Control, ctlLabel() As Control
Dim cl As Class1
Sub makecon()
Set cl = New Class1
Dim n As Integer
ReDim ctlLabel(3) As Control
Set ctlFrame = Form1.Controls.Add("VB.Fra
With ctlFrame
.Visible = True
.Left = 0
.Top = 0
.Height = 5000
.Width = 5000
End With
For n = 1 To 3
Set ctlLabel(n) = Form1.Controls.Add("VB.lab
Set ctlLabel(n).Container = ctlFrame
With ctlLabel(n)
.Visible = True
.Caption = "xxxx"
.Top = .Height * n
.Tag = n
End With
Next
Set cl.ContLabelSet = ctlLabel(1)
End Sub
## Class1##
Private WithEvents ContLabel As Label
Public Property Set ContLabelSet(obj As Object)
Set ContLabel = obj
End Property
Private Sub ContLabel_Click()
Debug.Print "click On Me"
End Sub

THat is how you can process a control Array in VB. When this event fires, it is passed the value os its index. Using that, you can get to know which control in the array has caused this event to fire.
Try this, use array of class
Dim cl() As Class1
Dim count1 As Integer
Sub makecon()
ReDim ctlLabel(3) As Control
ReDim Preserve cl(3)
Set ctlFrame = Form1.Controls.Add("VB.Fra
With ctlFrame
.Visible = True
.Left = 0
.Top = 0
.Height = 5000
.Width = 5000
End With
For n = 1 To 3
Set ctlLabel(n) = Form1.Controls.Add("VB.lab
Set ctlLabel(n).Container = ctlFrame
With ctlLabel(n)
.Visible = True
.Caption = "xxxx"
.Top = .Height * n
.Tag = n
End With
Set cl(n).ContLabelSet = ctlLabel(n)
Next
End Sub
Dim cl() As Class1
Dim count1 As Integer
Sub makecon()
ReDim ctlLabel(3) As Control
ReDim Preserve cl(3)
Set ctlFrame = Form1.Controls.Add("VB.Fra
With ctlFrame
.Visible = True
.Left = 0
.Top = 0
.Height = 5000
.Width = 5000
End With
For n = 1 To 3
Set ctlLabel(n) = Form1.Controls.Add("VB.lab
Set ctlLabel(n).Container = ctlFrame
With ctlLabel(n)
.Visible = True
.Caption = "xxxx"
.Top = .Height * n
.Tag = n
End With
Set cl(n).ContLabelSet = ctlLabel(n)
Next
End Sub

hi ranjeetrain
if you see my done code the issue is to assign my each control array element on seperat variable
then and then it fire its events perticularlly
if you try the answer you wrote you will get error .... pls take a look second time
tx for you time
hi eddykt
the solution which you gave me the first problme in that
you Not can
Set cl(n).ContLabelSet = ctlLabel(n)
and second i like to catch that event of perticular label clicked on class lavel how can i catch that ??
i think you understand what i mean to say tx

Change
Set cl(n).ContLabelSet = ctlLabel(n)
to
Set cl(n) = New Class1
Set cl(n).ContLabelSet = ctlLabel(n)
Also change
Public Property Set ContLabelSet(obj As Object)
to
Public Property Set ContLabelSet(ByVal obj As Variant)
Set cl(n).ContLabelSet = ctlLabel(n)
to
Set cl(n) = New Class1
Set cl(n).ContLabelSet = ctlLabel(n)
Also change
Public Property Set ContLabelSet(obj As Object)
to
Public Property Set ContLabelSet(ByVal obj As Variant)
If you can to catch the particular, then
In you class, add the method like
Private m_Num as integer
Public sub GetNumber(byval num as integer)
m_Num = num
end if
Private Sub ContLabel_Click()
Debug.Print "click On Me " & m_Num
End Sub
In you module
Set cl(n) = New Class1
Set cl(n).ContLabelSet = ctlLabel(n)
cl(n).GetNumber n
In you class, add the method like
Private m_Num as integer
Public sub GetNumber(byval num as integer)
m_Num = num
end if
Private Sub ContLabel_Click()
Debug.Print "click On Me " & m_Num
End Sub
In you module
Set cl(n) = New Class1
Set cl(n).ContLabelSet = ctlLabel(n)
cl(n).GetNumber n

hi eddykt
tx a lot actually i not prefere lots instance of class
but accourding your solution my problem is solved so thanks again
so i am accepting your solution
i facing another prob actually i am raising this question too in EE
on class lavel there is one with event of label and i want to call
procedure which i created in Usercontrol in this event
#Form1##
Option Explicit
Dim k As Class1
Private Sub Form_Load()
Set k = New Class1
Set k.ContLabelSet = Label1
End Sub
#class1#
Option Explicit
Private WithEvents ContLabel As Label
Private Sub ContLabel_Click()
MsgBox "hi" '*** Here i want to call Procedure of Usercontrol1
' ProUserControl
End Sub
Public Property Set ContLabelSet(obj As Object)
Set ContLabel = obj
End Property
#UserControl1#
Public Sub ProUserControl(para As String)
MsgBox para
End Sub

That's how natural of OO program works. Too bad if you don't like it

You just need to use the correct syntax of the Event Handler. It should read like this:
Private Sub ContLabel_Click(Index as Integer)
Debug.Print "You clicked on the agent with the index " + ctr(index)
End Sub
