Hi, Yes, you would need to use the ArcGIS Mobile SDK which currently, as far as I know, needs to work against a mobile enabled map service provided by ArcGIS Server. Using the create mobile cache GP tool in the toolbox creates an entirely new mobile cache each execution, which means you can't use it to incrementally build up a larger cache over several executions.

Hi, I've read your other related post too. Just to confirm a few things: Are you using ArcGIS Mobile 10? Are you directly using the SDK or extending the out of the box application using the SDK? Is the layer in the cache from an SDE geodatabase? Has the GlobalID field been added to the source Feature Class using the ArcCatalog "Add Global IDs..." context menu option? Thanks, Steve ...

Hi, On a per layer basis, try using FeatureLayerSyncAgent and its Synchronize method.  I believe this is still synchronous but provides feedback via ProgressChanged and StateChanged events.  It also provides a FeatureLayerSyncResults object as the return result of calling Synchronize.

Hi, Try assigning the updated polyline back to the geometry object of the DataRow before calling featureLayer.SaveEdits(featureDataTable): featureDataTable.Rows[0][geometryColumnIndex] = polyline; Thanks, Steve ... View more

Hi, Is it possible to create a non-rectangular mobile cache from ArcMap? I already tried to: Use clipping on the map, but the CreateMobileMap_mobile tool seems to ignore this Use a definition query: Based on the area, I select the objectid's, and create a query such as 'objectid in (1,2,3, ...). This works for small sets, but since the definition query's textbox has a maximum of 30,000 characters, larger sets don't. Any other ideas? Hi, I don't think it is possible to create a mobile cache using non-rectangular extents. However, if the goal is to create a mobile cache that more closely approximates the outline of the area you need data for, you could build the cache using the SDK. Using the SDK you could build the cache requesting many different rectangular extents.  This could give you a better fit to the area you want to base the cache on. Unfortunately, I think you have to use the SDK, as I don't think the GP tool will allow you to do this as it will create an entirely new mobile cache each execution. Thanks, Steve ... View more

I believe this is true pre ArcGIS Mobile 10. Pre 10 the refreshData parameter had to be set to true to refresh the cache data for the chosen extent and layers. This refresh involved the download of all data within the extent for the chosen layers. If the refreshData parameter was set to false, then only new features (adds) not already in the mobile cache would be downloaded. At ArcGIS Mobile 10 only deltas (adds / edits / deletes) are downloaded for the chosen extent and layers. ... View more

1- Are the geodatabase Tables included in the MobileCache (when generated)? 2-If yes (they are included), can someone post a way to access those tables? 3-If No (if they are not included) what is the alternative to access those tables? This is quite a common query / issue at ArcGIS Mobile 10 and previous. 1 - No, object tables are not support by ArcGIS Mobile 2 - N/A due to 1 3 - Possibly the most common method is to create a feature class to represent the tabular data as this is compatible with ArcGIS Mobile. In addition, relationship classes / relationships are not supported.  If you are using an SDE geodatabase you may be able to model specific database views that will allow for an acceptable display of related data within ArcGIS Mobile.  Otherwise, you could customise and recreate the relationships between the feature classes on the client and develop the appropriate workflow(s) to display the related data. ...

Has anyone done that?  Is there anyway of accessing the amp file setting through the code? Does this help? It's for a custom extension, but should transfer to a custom task ok.  I've included code for the Project Center extension, project extension and shared settings classs. Note: You must serialize out exactly the same settings that are deserialized in, otherwise the AMP file will become unreadable.

I've experienced error 1017 when the mobile cache mapschema.bin file describes a data connection that cannot be connected to / is not available. You can use a hex editor to view the connection data that is stored in the mapschema.bin, then verify that this connection is available to your server. Is it possible that during the move of the services from your development machine to your server the data connections changed / became broken? ... View more

I actually just posted the same topic as a new thread, missed this one.  We are having the same issue with Corrupted or Invalid project files and are trying to figure it out.  In the mean time as a quick and dirty fix we use a .bat file to replace the corrupt AMP file with a good one (original copy stored on the C drive in a Fix Corrupt Project folder with the .bat file).  This saves our field users a trip back to the office.  The field users know when they see that error to let us know but by double clicking the .bat file they can keep working.  In our case the data is fine and nothing is lost. In our case the corrupt projects seem to be random with no clear reason as to why.  In a lot of cases our field users with close the application at the end of the day they can't open it again. We have also encountered this issue and implemented a similar workaround.  However, the workaround becomes complex when you factor in that the AMP file can contain custom searches that the user has created, as well as the last visible extent.  These would be lost when the AMP file become corrupt. We have seen the corruption when there is an application crash, the battery runs out or on a device or the device is suspended e.g. the lid is closed on the device. I believe NIM059002 may refer to this issue, although this states the problem is fixed at ArcGIS Mobile 10 final: http://support.esri.com/en/bugs/nimbus/TklNMDU5MDAy ... View more

Do you mean that i need to install the Mobile software on each device where I want to deploy my custom application on (built using the Mobile SDK) ?  My AGS Mobile 9.3 custom applications didn't require any additional software installation I was able to solely deploy the custom app. It was the same at 9.2, you could deply without any additional software installation.  However, it seems at 10 you need to somehow get the key that "Missing ArcGIS registry key" refers to onto the machine.  This seems to be achieved by installing the ArcGIS Mobile Windows application.  I'm not sure how to achieve this otherwise. ...

You mention that you have configured all the projects in VS.NET to build for x86 target.  This is necessary. You may also need to ensure that the ArcGIS Mobile Windows application or the SDK is installed on the machine to provide the necessary key. ... View more

My experience mirrors your own. Have you tried manually calculating whether the layer is within the scale range? e.g.             MapLayer associatedMapLayer = map.MapLayers[associatedFeatureLayer.Name];             //InScaleRange method doesn't seem to work, MapLayer.MinScale and MapLayer.MaxScale             //values seem to be wrong way around, so calculate our own             bool inScaleRange = (map.Scale <= associatedMapLayer.MinScale) && (map.Scale >= associatedMapLayer.MaxScale);             //if (associatedMapLayer.Visible /*&& associatedMapLayer.InScaleRange(map.Scale)*/)             if (associatedMapLayer.Visible && inScaleRange)             {...} ...
