All, This is a question that I hope has been asked before: Is there any way for my users to load a shapefile into my SFV while retaining the attributes and the symbology of the layer file? I downloaded and am using �??Shape File Overlay for Sample Viewer�?� from the ArcGIS resource Center, submitted 3-4-2010 by �??HardWork�?�. It works great, but I need it go a step further. // Shape File Overlay for Sample Viewer http://resources.esri.com/arcgisserver/apis/flex/index.cfm?fa=codeGalleryDetails&scriptID=16846 // I really need the symbology and attributes to make it complete. Has anyone done this? Any suggestions would be incredibly appreciated!!! I have 2 applications using Web Mercator & WGS84 Sample Flex Viewer: flexviewer-src-1.0.zip (Build 06.12.09) agslib-1.2.swc flex_sdk_3.2 Required Adobe Flash Player version 10 Attached are 2 sample shapefiles (and .lyr files) in both projections: (102100, 4326)
2) Use the GeometryService project method to project geometries between any coordinate system. This will send the request to the server which will project it.
Note if using the 1.x API, the GeometryService took graphics, in 2.x it takes geometries instead.
Bjorn, Thank you for the direction. I really appreciate it. I've been trying to get "WebMercatorUtil.geographicToWebMercator" into the ShapeFile_Overlay_PLP code from Ricky Gonzalez. Can you show me how this is done? I've been at it all morning. (I get in pretty early.) I am using: SFV: flexviewer-src-1.0.zip (Build 06.12.09) agslib-1.2.swc flex_sdk_3.2 Required Adobe Flash Player version 10 (We are switching server architecture and can't move to ArcGIS 10 or Flex 2.0 until early next year.) Thanks for your help.
hi i downloaded the atached fzip and it returns me tha the zip file is invalid coul you send me the code to my personal email oletic@gmail.com, thanks a lot
I've quickly converted to the SFV 2.0 Beta 2, if anyone wants it.
I've included the compiled version and source code.
DISCLAIMER: A quick modify of the existing widget to bring it up to flex 2.0, code by others ....
p.s. it would be interesting to extend this to have the same graphics colors etc control as the advanced graphic widget in sfv 1.3 (we have one for SFV 2.0 - using flex 2.0 api) and have the ability to push the graphic (which is now geometry) into a feature layer as a new edit feature ... 🙂
Anyone thinking of doing that?
Cheers Coomsie
Attached is a modified version of the shapefile overlay widget that allows you to modify the symbology, displays the first attribute and supports points, lines and polygons. You will need to have the original shapefile widget installed and update with the attached files.
Let me know if this works for you. If it does, I can post it to the code gallery.
DISCLAIMER: An intern in my group modified the widget, so I didn't write the code.

Mr. Gonzalez, I've tested your PLP version of the ShpOverlay and it works great for polygon shps in both WGS84 and Web Mercator flex applications. (SFV 1.0) I did come across a point location error in a WGS84 the application. (It works fine for my Web Mercator app.) Have you tested the correctness of the point locations for a point shapefile input? (I did not test a line shapefile.) The points are all pulled towards the center of the map 0, 0 anywhere from 20 - 70 miles. Please let me know what you come up with. Have you given any thought to: - Allowing the user to choose the label field? - Display using a color ramp for multi - feature polygon? - A place in the code to convert projection? ie. Input shapefile WGS84 (4326) - Output projected graphic of shapefile in Web Mercator (102003) application. Thank you again for hard work on the PLP version you posted.

I just figured out what is going on: The offset of the graphic points generated by our tool was so random that I was curious about their LAT LONGs. I was right, each graphic point was right to the whole number. If the point was -85.9495, 33.6794, the graphic point would be located at -85.00, 33.00. And the reason it works perfectly for Web Mercator is that it uses whole numbers in meters. I hope this helps in your adjustments.

As I indicated in my original post, I didn't write the code so I didn't do any testing. I haven't really looked at the code in depth to support it or add additional functionality. I just posted the code since people were asking for the functionality and I knew it would be useful. Once my environment has been upgraded to API version 2.0, I will revisit this widget and see if I can include some of the changes you requested.
That's great! I have issue with opening the file. It says 'it's not a valid zip file'. Any one has the same issue at all or I missed something?
Thanks.

Hi Thomas,
How did you get the widget to re-project in your Web Mercator application?
Also, to fix the point issue in your WGS84 widget, change the following in "ShpPoint.as": private var xcoor:Number;
