[SOLVED]Is there a way to get full extent of polygon without looping through features

Question

This is hopefully an easy one for someone but my searches have given up nothing on the subject.

Is there a way to get the maximum extent of a polygon shapefile without looping through each of the features in the featureclass?

I have a polygon with 100,000+ features in it.  I want to have the maximum extent of the polygon for another operation I am doing.  It seems silly and time consuming that I would have to loop through every single feature to get the maximum extent.

Please help.

Thanks!

That was the trick, thanks a million agray1.

so for anyone else scratching their heads on this one here is the code snippet
Dim pFWS As IFeatureWorkspace
Dim pWSF As IWorkspaceFactory
Set pWSF = New ShapefileWorkspaceFactory
Set pFWS = pWSF.OpenFromFile("C:\Temp", 0)

Dim pfeatureclass As IFeatureClass
Set pfeatureclass = pFWS.OpenFeatureClass("PolyShapefileName")

Dim pgeodataset As IGeoDataset
Set pgeodataset = pfeatureclass
x1 = pgeodataset.Extent.XMax 'this is the right most point of the polygon extent

Thanks!

The featureclass class implements the IGeodataset that has an extent property, is this what you are looking for?
