Creating ... controls

[iScanning]

Hi PPL!


i was so thrilled with the fact that i finally knew how to write code for the control being created in the future with the vb.controls.add, using the withEvents function, but my happyness dyed soon cause what i need to do is not only program for one or two controls, say labels, but for say 30 labels, i tryed to make an array with WithEvents, but it's not possible, any suggestion?

Thanks guys!

If you start off with a Label, with an index of 0, you can create replicas.

Public ReplicaLabel(1 to 30) As New Label1

Private Sub Form_Load()
'Whenever you need one simply do this.

Load ReplicaLabel(1) ' or whatever number.

With ReplicaLabel
 .Top = 0
 .Left = 0
 .Visible = True
End With

End Sub

That code also works for any object, like forms, except MDI forms I think.

Just be careful though, if you try to load a replica twice the program will give the error 'Object already loaded.'

Thankx DreamLax!

But theres something i don't know either! I want the user to create the labels he or she wants, but i want to write code for each label that could be added, say label has one behaviour the second a different behaviour! The thing is since i have to this with many other different controls i would like to find now a way to write code without using WithEvents for each of the 80 possible controls to be added!

Thanks for the help!

If you want to write the code you could just write your 80 subs and then call whatever sub from the click on whatever control you wish to use.
example:

Option Explicit

Public Sub sub0()
    MsgBox "zero"
End Sub

Public Sub sub1()
   MsgBox "one"
End Sub
 
Public Sub sub2()
   MsgBox "Two"
End Sub

Public Sub sub3()
    MsgBox "Three"
End Sub
  
Private Sub Form_Load()

'load an array of controls at runtime
Dim intcre As Integer

Do Until intcre = 3
    intcre = intcre + 1
    Load Label1(intcre)
    Label1(intcre).Left = Label1(0).Left
    Label1(intcre).Top = Label1(intcre - 1).Top + Label1(0).Height + 100
    Label1(intcre).Visible = True
    
Loop

End Sub

Private Sub Label1_Click(Index As Integer)
    Select Case Index
    Case 0
      Call sub0
    Case 1
      Call sub1
    Case 2
      Call sub2
    Case 3
      Call sub3
    End Select

End Sub

Also, consider this. If you have a finite number of label styles, you can always hide the type of the label in the Tag property of the label. IE: Label1(0).Tag = "IPLABEL". Then, you can specify the events you need for each specific style. You can possibly even use CallByName to call specific functions based on that tag:

    CallByName Me, Label1(X).Tag & "_MouseDown", _
               VbMethod, Button, Shift, X, Y

Keep in mind that methods/properties called by CallByName must be Public for them to be used.

This way could kill off a select statement, but would give pause to the number of functions available outside of your control.

Hope this gives you some ideas.
