Hi Greg. You can use LayerInfo( n, LAYER_INFO_DISPLAY) to determine if an override is set. Check out the LayerInfo() function in the help file for the return codes.

Since your mail reader does not understand this format, some or all of this message may not be legible. Listers, Is there anyway when switching a layer on in MapBasic to know whether a global style override has been set? The reason I ask is that we have a small MapBasic application that switches loaded raster images on and off. The only problem is when an image has been switched off and a style override has been set for the layer, when it's switched back on again it displays as default (without the style override). Looking at the MapBasic reference guide it's only possible to switch a layer on as either GLOBAL (with style override) or GRAPHIC (as default). So if you use GRAPHIC it ignores any previous style overrides that had been set or if you use GLOBAL this displays with style override regards of whether it was set previous to being switched off. Any ideas on how I can get round this and know when a style override has been set? Thanks in advance.
