Dear Sir,

A Stock Exchange template made in Xpression designer is not loading in the iNews

due to an error that happens when I try to change the arrows textures (from "Green UP arrow" to " RED down arrow" or "Yellow dash"). Knowing that it is a Quad with a png texture. Is there another way to change between arrows? A script maybe ! rather than changing texture by choosing different png ? Please advise. Thanks. (N.B: how can I send you the project if necessary ?)

This can easily be done with a script. We do it here and it works great. Here's a sample code. It assumes you have a text object for the total change of a stock value.

dim change as xpTextObject

dim changeval as Single

dim quad as xpBaseObject

dim red as xpMaterial

dim green as xpMaterial

dim yellow as xpMaterial

'assign to objects

Self.GetObjectByName("Change Text Object", change)

Self.GetObjectByName("Display Quad", quad)

Engine.GetMaterialByName("Red Arrow", red)

Engine.GetMaterialByName("Green Arrow", green)

Engine.GetMaterialByName("Yellow Dash", yellow)

'get the value of the change text object, turn it into a number to work with

changeval=Csng(change.Text)

'here's the actual work, where it just looks to see if the value is positive, negative, or zero

'then sets the appropriate material on your quad

if changeval > 0 then

quad.SetMaterial(0, green)

elseif changeval < 0 then

quad.SetMaterial(0, red)

elseif changeval = 0 then

quad.SetMaterial(0, yellow)

end if
