Hi!The gda_data_model_dump_as_string() creates a string which contains the whole datamodel's values(it's mainly intended for debugging), basically gda_data_modeil_dump() is just a wrapper around that function.You should use:const GValue *value;value = gda_data_model_get_value_at (model, 0, 0, &error);if (! value)gchar *str;str = gda_value_stringify (value)
