Jeff:  Are you using the .NET bindings?  If so, there is a newer version 
that resolves some errors in the binding.

[Shapelib] help with SHPWriteObject

I am having problems whenever I call the SHPWriteObject routine.  I?m able 
call all of the other routines that I need.  I get an ?Access Violation? 
when making the call to SHPWriteObject.  Are there any common mistakes 
that I could check?  Any guidance would be greatly appreciated.  Thanks? 
            hShape = SHPCreate( szRemotePath, SHPT_POLYGON );
            hDBF = DBFCreate( szRemotePath );
            vPolygonNum.vt = VT_I4;
            vPolygonNum.iVal = 0;
            KSHAPEFILES_AddFieldsToDBFNoConnection( hDBF, nTypeInteger, 
vPolygonNum, nPrecision1, nNumericScale0, strPolygonNumber );
                            phObject = SHPCreateSimpleObject( 
SHPT_POLYGON, knotCounter, dXPos, dYPos, dZPos );
//                                  nObject = SHPWriteObject( hShape, 
knotCounter, phObject );
                    SHPDestroyObject( phObject );
// Polygon Number
                                    vPolygonNum.iVal = nThisPolygonNum;
                                    KSHAPEFILES_WriteAttributeToDBF( hDBF, 
knotCounter, 0, nTypeInteger, vPolygonNum.iVal );
DBFClose( hDBF );
SHPClose( hShape );
