<P class=MsoNormal><FONT face=Arial size=2><SPAN
style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">For some reason mapguide is unable
to understand the geometry of my shapefile. The shapefile is a polygon with the
geometry information contained in the ‘Shape’ field. However when I use the
‘Shape’ field in the following code I get an error which states: “The specified
object was not found – GetItem line 115”. </SPAN></FONT></P>

<P class=MsoNormal><FONT face=Arial size=2><SPAN
style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">
$byteReader = $featureReader->GetGeometry('Shape');</SPAN></FONT></P>
<P class=MsoNormal><FONT face=Arial size=2><SPAN
style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">
$geometry = $geometryReaderWriter->Read($byteReader);</SPAN></FONT></P>
<P class=MsoNormal><FONT face=Arial size=2><SPAN
style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">
$point = $geometry->GetCentroid();</SPAN></FONT></P>
<P class=MsoNormal><FONT face=Arial size=2><SPAN
style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">
$x = $point->GetCoordinate()->GetX();</SPAN></FONT></P>

<P class=MsoNormal><FONT face=Arial size=2><SPAN
style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">so what I think should happen here
is the GetGeometry function should look at the ‘Shape’ field, identify that the
shapefile is a polygon, then get the xy coordinates of the centroid of the
polygon which is then sent to another function which can then zoom to
those coordinates. But I keep getting the error that I mentioned. Could anyone
point me in the right direction?</SPAN></FONT></P>
