This undocumented feature of VB6 lets you create new controls at run time. In previous versions, one had to create a control array at design time in order to be able to add new controls in run time, which would then be the members of the control array. But in VB6, you can do it without a control array.
Paste following code in the Form's code window:
Dim WithEvents mctlCommanButton As VB.CommandButton
Private Sub Form_Load()
Set mctlCommanButton = Me.Controls.Add(VB.CommandButton,
mctlCommanButton.Caption = Hi
mctlCommanButton.Left = 10
mctlCommanButton.Top = 10
mctlCommanButton.Visible = True
Private Sub mctlCommanButton_Click()
Similarly, you can create any control. For example, for a Timer control, use VB.Timer instead of VB.CommandButton in the above code.
