Well, turns out the code works, the problem was that I was drawing a line, and the layer and feature source seemed to only accept polygons.
Regardless, I got what I needed from the example. Thanks for the response. J As far as your question... Yes, I am able to programmatically create a layer and save it permanently.

My experience is that I translated the same code ( the developer's guide example : task_pane_redlining.php & draw_line.php ) to C#. And it works fine, but I just could draw a line or a polygon temporarily stored in the session repository. So, according to your question, I am not sure that your code can create a permanent layer with feature source stored in the "Library://" or they are just stored in the session step. I am hurry-skurry to know how to create a permanent layer stored in the "Library://". I think the steps should be : 1. Login by "Administrator","Admin". 2. Open/Create Map with MgResourceIdentifier(with "Library://...") 3. Save the map to the "Library://". But I have tried many different parameters in Open/Create/Save MgMap, but I still can't make it works successfully. If you have correct steps or code could demonstrate how to create a layer with a feature source permanently, please provide me, I would deeply appreciate it. Thanks. Patrick.

I'm using the developer's guide example (task_pane_redlining.php & draw_line.php) which I have translated into VB. I can create a layer programmatically, and set it's feature source to an existing layer, and things work fine. But I cannot create the temporary feature source, draw a line, and create a layer and then have that show up on the map. The layer shows up, and no errors occur in the code, and I am even able to query the feature source, and it all seems to work...... except that nothing shows up on the map. If someone could provide an example of creating a feature source in .Net and/or creating a feature source, and a layer programmatically, I would greatly appreciate it. Thanks.
