How Do I Programmatically Scroll a Listbox Control in LabWindows/CVI

Problem:
How do I make my Listbox control scroll to show the most recently added data automatically?

Solution:
You can insert items to the end of the Listbox control by passing a -1 to the item index parameter.  Then, find the current number of elements in the Listbox.  Lastly, set the active row to the last item.  This procedure is demonstrated in the following code.

InsertListItem (panelHandle, PANEL_LISTBOX, -1, "Item in Listbox Name", 0);
GetNumListItems (panelHandle, PANEL_LISTBOX, &size);
SetCtrlAttribute (panelHandle, PANEL_LISTBOX, ATTR_CTRL_INDEX, size-1);
