Generate Geodatabase Extend Problem

[tanerkoka1]

  Hi,

   We are using Arcgis Runtime SDK for Qt 10.2.6 and Qt 5.4.2 (MSVC 2013, 32 bit) Qt Creator QT\QML side .We have local editing application which edits features within an offline geodatabase and sync back to the service.We are using GeodatabaseSyncTask class's generateGeodatabase (GenerateGeodatabaseParameters parameters, string filename) method to generate geodatabase.

Can I generate geodatabese using without GenerateGeodatabaseParameters's  extent  property ? can I generate using only layerIds or layerQueries​ properties ?

I'm tried to generate witout extent propery with using only layerIds and layerQueries but when I can not generate , here is the console output below:

D/MaksMobil(30477): qrc:/qml/MapNumarataj.qml:291 (onGenerateStatusChanged): qml: Generate Error messageFailed to parse geometry from input JSONcode400

Best Regards

extent/geometry is a required parameter from the rest api, so you will need to provide it - Create Replica - Feature Service (Operation) - ArcGIS

Thanks Lucas,

Can we generate geodatabese only within poligon geometry not within poligon geometry envelope using with GeodatabaseSyncTask class's generateGeodatabase, Can we use    generateGeodatabaseParameters.extent=polygon; line of code , not generateGeodatabaseParameters.extent=polygon.queryEnvelope(); line of code  ?

Thanks

I believe that should work, as it takes a Geometry - ArcGIS Runtime SDK for Qt QML API: GenerateGeodatabaseParameters Class Reference

Hi Lucas ,

I try to generate with poligon (generateGeodatabaseParameters.extent=polygon)  wich has more than one point but gives error when I generate .How can we solve this problem ?

Here is the console output below :

Taner,

The following code works for me, so in general, it does work to have a polygon as your extent in the generate task

Hi Lucas ,

Thanks for example code , works fine but in my example have more then  1000 or 2000 point. Can you try to set over 1000 or 2000 point in polygon maybe there can be limitation points or request limitt in polgon when we  query during the generate geodatabas.How can I solve this urgent problem ?

Thanks
