With this code, I've made a control at runtime.

Set btnObj = Controls.Add("VB.ComboBox", sControlName)
With btnObj
.Visible = True
.Width = 2000
.Top = 210 + (i * 350)
.Left = 5500
.ForeColor = vbBlack
.Text = ""
End With

Now I want to remove it. So I thought to set it equal to Nothing:

Set btnObj = Nothing

The problem is, that the control is still on my form.

How can I realy remove it?
