Dheeraj,
I don't think the OSGeo.OGR.Layer.Intersection supports progress
notification. You might probably have encountered a bug which should
be fixed. Do you have a sample code to reproduce this issue? I would
specifically interested in the actual geometries have been passed to
the function.
Layer::Intersection supports progress notification but support in the
Swig layer may not be complete. There is of course a possibility of a
bug in the Layer::Intersection code too.

Hi list,
I have troubles with C# bindings of OGR. I was trying to perform
intersection on two feature classes (shape file formats) using
OSGeo.OGR.Layer.Intersection(), but have problems making it work.
I keep getting an error saying "AccessViolationException was
unhandled. Attempted to read or write protected memory. This is
often an indication that other memory is corrupt.
Is the above error something to do with
SWIGTYPE_p_GDALProgressFunc callback and OSGeo.OGR.SWIGTYPE_p_void
callback_data arguments? I tried passing those parameters null as
suggested by some in the forums butI keep getting the error
"Attempt to dereference null GDALProgressFunc". I am not sure what
that means.
And when I instantiate callback as new
SWIGTYPE_p_GDALProgressFunc() and new callback_data as new
SWIGTYPE_p_void(), I don't get error Attempt to dereference null
GDALProgressFunc, but still have error saying
AccessViolationException was unhandled. Attempted to read or write
protected memory. This is often an indication that other memory is
corrupt.
Can someone please help me figure this out and let me know how to
make use of OSGeo.OGR.Layer.Intersection() in the right way with
c# bindings. Thank you.
Thanks,
Dheeraj
