Using the Mouse wheel to select items in either a table or a Multicolumn

[Jr_Cigar]

I am trying to design either a Table or a MultiColumn List Box that I can use the Mouse Wheel to select without holding down either the Shift Key or the Ctrl Key. Has any one found a way to do this in LabVIEW 7.1?

I can't say I understand how you would use the wheel to select, but you can read the scroll wheel information with the mouse input VIs that ship with LabVIEW. There should be an example somewhere here which shows how to use it to scroll a listbox.

I've done multiple selection by simulating a click on ctrl when the user enters a listbox and releasing the click when the user leaves by using the Mouse Enter and Mouse Leave events for the control.

The actual keyboard simulation was done using a simple call to the Windows API and there are many VIs both here and in the NI forums which do this. Just search for "simulate keyboard'.
