VB.Net - GetGeometry only returns a ShapeBuffer

DavidTriggs

I have been playing with the API in VB.net and can not get a geometry from the GetGeometry() function.

According to the C# examples:
PointShapeBuffer pointGeometry = row.GetGeometry();
          point = pointGeometry.point;

In Vb.net the GetGeometry function explicity states it returns a ShapeBuffer. It will not accept a CType converstion to PointShapeBuffer, and will not accept a PointShapeBuffer as an output. The Help states the Geometry function returns a ShapeBuffer so I do not understand how to get a point from (Get)Geometry function.

Any advice would be appreciated.

Anyone still having problems with this in VB.Net?  I ran on to the same problem with version 1.4 as well as 1.5. I wrote a C# DLL with some "Get Geometry" functions to deal with all the buffer types.  One point to note is that when the new geometry is returned, it still shows as a ShapeBuffer in debugging, but you can still access the PointShapeBuffer, MultiPointShapeBuffer, MultiPartShapeBuffer, MultiPatchShapeBuffer properties regardless.  I hope this helps someone:

Usage:

Imports ESRIFileGDB.ConvertShapeBuffer

.

.

.

Dim geometry As New PointShapeBuffer = GetPointGeometry(row)
