Simon,

You might be very lucky :-)

A patch has been just posted at http://fdo.osgeo.org/patches.html
The symptoms you reported (crash on describe schema) fit the bug fixed by this patch.

Let me know how it works,
Dan.

Dan,

Yes it's ArcSDE 9.2 on top of SQL Server

Cheers

Simon

Hi,

Is your database a SqlServer one?

Dan.

Hi,

I'm a beginner trying to work through the developers guide and using the
FDO
.Net API. I'm trying to get details of the schemas in an ArcSDE 9.2
connection:

//create a command to describe the schema
OSGeo.FDO.Commands.Schema.IDescribeSchema cmdDescSchema =
(OSGeo.FDO.Commands.Schema.IDescribeSchema)fdoConnection.CreateCommand(O
SGeo.FDO.Commands.CommandType.CommandType_DescribeSchema);

//create a set a featureSchemaCollection using the IDescribeSchema
command
OSGeo.FDO.Schema.FeatureSchemaCollection fsCollection;
fsCollection = cmdDescSchema.Execute();

The code is crashing when i try and execute the command, rather nasty
with
no means to dig any deeper. I have checked that my command has a
connection
and that the state of the connection is open.

Does anybody have any ideas? On a related note does anybody have sample
C#
code which i could use as a reference guide to get going with the basics
of
FDO - or is there any sample C# solutions in SVN that i could use?

Cheers

Simon
