Add Point Graphic From Lat/Long

Permanently deleted user

12. Juni 2015 03:22

I am developing a workflow that allows a user to enter a route and ref post and the map zooms to and creates a point graphic. At this point I get a LAT/LONG returned from our LRS system.

My question is how to use the LAT/LONG string values to generate a point on the map? I assume I have to convert these to a double variable type and I should probably use the 'AddMarkupGeometry' found in the 'RunExternalCommand' tool. What parameters do I set? The documentation is lacking this piece of the puzzle.

Thanks.

  I think I have the logic down, however, when I run the tool, I get this error: 

  There was a workflow error running activity: Exception has been thrown by the target of an invocation. Workflow 'Zoom to Route' failed Aborted exception: 'The calling thread cannot access this object because a different thread owns it.'. The calling thread cannot access this object because a different thread owns it.

  I have checked the scope of all the variables and they seem okay to me.

  This isn't the full code, just the piece that adds the graphics after I retrieve a LAT/LONG in string format:

  Lat: 41.7795205378011   Long: -93.5706273723725

  Any help would be appreciated.

  Rick, 

  That's much more elegant than my hack. Thanks!

  This is great to create a point and zoom to it. However, I am looking to create a graphic like this:

  /customer/servlet/servlet.FileDownload?file=00P6000000em16dEAA

  Anyone have a sugesstion on how to accomplish this? I have the required already before I get to this point, I just don't know how to make it a label nor do I know how to add this symbol instead of a generic dot.

  Thanks!

  The workflow is cut off and I cannot load it. Can you please repost?
