Gavin, In ArcPad 10 when in ArcMap I can use the Get Data for ArcPad wizard to check out data from different geodatabases into a single axf database and one layer can be editable the other read only. The read only never appears in the editable layers menu on ArcPad. You would set one layer as Action > Export as background data (to AXF layer) > Make read only and for the editable layer you code do Action > check out for disconnected editing > check out schema only. So yes you can have editable and read only in a single axf file. Duncan ... View more

Gavin, If you have layers that are only ever going to be read only maybe you should export those to Shapefile for better performance. AXF may be the all singing and dancing solution to most storage solutions but I have found them to be a bit flaky sometimes, especially when one has more than 4 layers in an AXF (well that's my experience anyway).  Check this page out about ArcPad and Shapefiles.

Demetris, I've restructured your code. Have a look. You should really get into the habit of documenting your code with comments, this is good programing as it allows others to follow the code easier.

Diss, I created a VB AddIN and in the onclick event I put this code together and got it working. It looks like the input layer has to be a featurelayer object and not a string.

Could try the tool feature vertices to points?   http://help.arcgis.com/en/arcgisdesktop/10.0/help/index.html#/Feature_Vertices_To_Points/00170000003p000000/ ... View more

Are you saying the vertices of the polygon contain z values? You could convert your polygon to points with z values then convert these to pixels with their z values. ... View more

If you look at the help on this geoprocessing tool it says: The CONVEX_HULL, CIRCLE, and ENVELOPE options are only available with an ArcInfo license. Are you using ArcInfo? ... View more

Jarek, I think its to do with correct topology of the polygon. If you look at the Help on the Check Geometry tool it mentions what direction an outer ring a polygon should be. I guess when you copy the polygon into the polyline featureclass ArcMap is enforcing correct topology for the polygon and consequently your polyline ends up clockwise. Well thats my guess of whats going on... Duncan ... View more

James, Is your point data "stacked", i.e. you have lots of points that have the same XY coordinates? I think the tool ignores stacked points so may be this is reducing your dataset to less than 10? Also (not sure about this) may be you have set the output cellsize tool large and eveything falls within one cell? Duncan ... View more

David, Can you zip up some sample data that it fails on for others to review? Duncan ... View more

Just a guess here, but could it be possible that the feature to polygon tool is generating a Feature Class that contains no data?  A newer geodatabase will support a higher level of precision and so none of your polylines form polygons, whilst an older geodatabase has a lower level of precision and everything "snaps" to form enclosed areas?

David, So let me get this straight. At some point your model generates 2 layers each containing 1 polygon and you are using the spatial join tool on these? Have you tried to use the spatial join tool on these layers only (so not part of any model) to see what happens? If these polygons are not top secret maybe you can zip them up and post on this thread? Duncan ... View more
