"You can access the geometry like with any other ogr feature."
Yes, it's right. But how string are encoded with Ogr ?
Because I have to write :
[code]
byte[] memWkb =
System.Text.Encoding.UTF8.GetBytes(memFeature.GetFieldAsString("WKB_GEOMETRY"));
Geometry memGeom = Geometry.CreateFromWkb(memWkb)

Hopefully, memFeature.GetGeometryRef() should do it !

Driver seems to do what it promises. It is super fast in converting POI data
because it is possible to skip the slowe
Sorry, I was not clear.
I resume from the beginning.
I work with a warper C# of Ogr.
I have a table dbo.MY_TABLE with 3 fields (D, CHART_ID, WKB_GEOMETRY) in a
SQL server Database (in SQL Azure exactly).
*My aim is to work with a copy* (in a

Benjamin,
The mssql driver already does the conversion from wkb in the database to
the native ogr geometry format. You don't have to create a temporary wkb
geometry and then the ogr geometry.
You can simply do this:
[code]
Geometry memGeom = memFeature.GetGeometryRef()
[/code]

Hi Benjamin,
Can you provide some more details?
How did you try to retrieve the geometry?

Hi again Chaitanya,
If you look my previous mail you can see the code.
But in a compact way this is a copy/paste of my running code.
Note that RoleEnvironment.GetConfigurationSettingValue(“”) just provide me
parametrables strings (like argv[n]).
[code]
Ogr.RegisterAll();
string option
Benjamin,
First thing: You don't need to use a memory datasource here. OGR doesn't
make round trips to the database server every time you run
GetNextFeature(). Do that first. I'm sure it will make it less complicated.
I don't understand why you are getting the null. Hopefully we can figure
that o

Fascinating. Actually I think once someone imports the points, lines,
polys into a DB, then (cool!) someone could then

Hi friends,
When reading .DGN files, I can specify features (include attributes: Type,
Level, Text, ColorIndex,...), and geometry (polygon, point) of these
features.
But, do you know how can we assign (or specify) Text, Level elements for a
particular polygon ?
For example: The map include many
