Is the data of the shapefile also referenced with lat\long values of the 
same geographic coordinate system or do you need to translate them?
I think you could open the shapefile, get the bounding box stored in the 
file (maybe you have to go through all the shapes as the stored bounding 
box in the file must not be correct - at least I do this when loading 
shapefiles) and then compare it to your value.
