Building proper COM bindings for all the GDAL entry points would be a
substantial effort.  The more common approach for folks wanting to use
libraries like GDAL from VB is to compile it with the appropriate calling
conventions (stdcall I think) and then just call the C API entry points
directly from VB.  There are definately difficulties with some of the
data types but this is (I think) acheivable.

In fact, rather than pursuing COM bindings in the future, I would be more
interested in seeing .net bindings prepared for GDAL at some point in the
future.  This would make it available to all the .net enabled languages on
windows, including VB.net.
