Joe, A solution for you here. Assuming that the Listbox is simply placed on a form as its parent (The reason why I will explain later):
In the Listbox MouseMove() Method put the following: * Start Code LPARAMETERS nButton, nShift, nXCoord, nYCoord =Amouseobj(aPosn) nX=aPosn(3)-This.Left nY=aPosn(4)-This.Top nTopItem=This.TopItemId nHeight=Fontmetric(1,This.FontName, This.FontSize) nGap=Fontmetric(4,This.FontName, This.FontSize) * nItem=Int(nY/(nHeight+nGap))+nTopItem This.TooltipText=Transform(nItem) Return * End Code This stores the List Item number of the element you are pointing to in the listbox into the TooltipText property of the listbox. I have used this for ease of explanation but you could of course use an added property. In the MouseDown() Event if you use the value: This.List[Val(This.ToolTipText)] This will return current selected value in the listbox which is what you want. Obviously you can then fire off the image display code for the temporary image. Note that this works when there are more items in the listbox than can be displayed at once i.e you scroll down.

I'm still wondering about this one - I posted this over the weekend and got no response. Maybe there is no way to do what I want and maybe my explanation needs revision. If it's clear and there is no answer I can live with what I have.

The active image is displayed along with a listbox of previously processed image files from a table. I want to allow the user to temporarily display any image from the list to verify that the active image is unique and not a duplicate of one already processed. > >I am using the mouse down event to display the temporary image and the mouse up event to redisplay to the active one. This gives the functionality I want but when I select a new item from the list, I need to click it twice in order to display the proper image. Apparently the listbox.value property is not updated until the mouse up event. My code reads the value property during the mouse down event. This explains the need for a double select when there is a selection change. > >My intent in choosing the select and hold approach is to prevent confusion about which image is being viewed.
