if i call gda_data_model_export_to_file i get an empty file; and if i call
gda_data_model_get_n_rows i get -1
The created data model's access is not random (because of the FALSE
argument to gda_data_model_import_new_file()), and so it cannot know
the number of rows it contains.
that's the last try that i did; before (and now) i used TRUE and i got
the same result
i have tried to call gda_data_model_dump immediately after
gda_data_model_import_new_file and i got
WARNING **: Could not dump data model's contents: Data model does not
support backward cursor move, not displaying data
Also the data model export functions don't currently work if the data
model does not have a random access (which is something I need to
correct). If you need to export DM, pass TRUE as the 2nd argument to
gda_data_model_import_new_file(), or you can use a
GdaDataAccessWrapper:
GdaDataModel *wrapper;
wrapper = gda_data_access_wrapper_new (dm);
...
g_object_unref (wrapper);
i'll try ASAP
thanks
