Spatial Reference Info

[ahuarte]

Hi!

I need read the SpatialReference info of a FeatureClass.

XML samples in the doc-SDK contains this description (WKT, WKID...) but calling to Table::GetDefinition() function it always returns no data.

I have test all sample gdb files and other personal gdb files FgdbV10.
What it's wrong?

thank you very much

Hi!
I test Table::GetDefinition() in the ExecutingSQL sample and it works OK.

I got to know how it fails!
I'm developing a C++ CLI/.NET with a 'ref class' which handle the FileGDBAPI::Table*.

This 'ref class' has two data member...

  FileGDBAPI:: Database*
  FileGDBAPI:: Table*

The database and table are open correctly. Envelope, RowCount, Search ... work fine!
Only "Table::GetDefinition()" return error.


if instead of using a database* I use database&, it work fine :confused:

I can rewrite the code, but I still question why the failure

thank you ver much!!!!

I just replied to the .NET Wrapper thread with this, but here is the summary:

It seems you must prefix the table name with a "\".  So in case of the ExecuteSQL.gdb database, if you want to open the cities table you'll want to make the call as OpenTable(L"\\Cities").  If you don't prefix the path with a "\", the table opens successfully AND the table definition is populated properly from the GetDefinition call.  However, the result code is -2147211775, indicating the path is not found.  Prefixing the table will make the function return 0.

This is made even more confusing with the samples opening the table by using both L"Cities" (Display/Querying) and L"\\Cities" (Editing).
