I am adding about at least 1500 to 3000 names to a combobox as show below.

Is there a better way of getting the names in the box? As I add more and more names it takes progressively longer to add a name to the list.

Any suggestions would be greatly appreciated.

Code:
    For i = 1 to Ubound(username)
        Me.cboOldUserName.AddItem (TempUserName)
        Me.cboMACLsUserName.AddItem (TempUserName)
    Next i
