I made a form and created a command button control. I would like to make it so that when the user presses the command button it sends a keystroke to a listbox of my choice.

Specifically, I want the command button to send a “down” arrow keystroke to a listbox (which will have focus) so that it goes from the current item to the next item.

How do I do this?

Let’s say the name of my listbox is “lstFruits”. I gave it focus, then tried SendKey.

Form.lstFruits.SetFocus.
SendKeys.Send ("{DOWN}")

Got the error “Argument not optional”.

    There is no need to emulate a keystroke, you can control the listbox in code;

    lstFruits.SetFocus
if ((lstFruits.listindex + 1) < lstFruits.listcount) then
    lstFruits.listindex = lstFruits.listindex+ 1
endif

    Edit

    Dim strName As String
strName = "lstFruits"

Dim lst As VB.ListBox: Set lst = TheForm.Controls(strName)

lst.SetFocus
If ((lst.ListIndex + 1) < lst.ListCount) Then
    lst.ListIndex = lst.ListIndex + 1
End If
