[Qgis-user] Only show some of the contours using a query builder

[jonathanmoules at warwickshire.gov.uk]

Mostly guessing here but it looks like the query builder in QGIS uses % as 
its modulo operator.
Try more traditional syntax like (this returns no errors in my QGIS):
"Elevation"%25=0

(Although wouldn't you want that to be 100 not 25?)

I have a shapefile containing 5 foot contours and I would only like to 
show
100 foot contours.  I am guessing I could use the query builder in the 
layer
properties but I don't know how to write the query.

Is this possible?

I know how to do this in ArcGIS (MOD ( "Elevation", 25) = 0) but the same
code does not work in QGIS.
