Hi all, I have a requirement to allow Edit and Delete of features in ArcGIS for Windows Mobile 10.1.1 based on certain attributes of selected/identified feature. E.g. if user selected a "pole" that has status set to "Survey Pending", then only surveyor should be able to edit its attributes otherwise it should be read-only. I cannot separate the data into two service layers based on Status making one editable and other read-only in Mobile for the reasons beyond my control. From my understanding of ArcGIS for Windows Mobile, I am trying to implement FeatureListBox.CreatingFeatureListBoxMenuItems event. However, in the event handler I cannot find a way to replace existing CanExecute event on the menu command with my own CanExecute event. Does anyone know how to do it? e.g code below protected override void OnOwnerInitialized() {   //...   FeatureListBox.CreatingFeatureListBoxMenuItems += new EventHandler<CreatingFeatureListBoxMenuItemsEventArgs>    (FeatureListBox_CreatingFeatureListBoxMenuItems);   //... } private void FeatureListBox_CreatingFeatureListBoxMenuItems(object sender, CreatingFeatureListBoxMenuItemsEventArgs e) {   //...   foreach (MenuItem currMenu in e.FeatureListBox.MenuItems)   {      // replace currMenu.Command.CanExecute ...   }   //...      } Regards, Vish ...

Hi, I have a customer who insists that ArcGIS for Windows Mobile should show "Table of Contents" as a dockable window so that user can easily know what each symbology represents. Use of Identify task to find out what layers user is seeing is not an acceptable workflow. Is there anything coming in version 10.2 that will meet this requirement. If not, has anyone tried to implement "Table of Contents" as a customisation/extension? If so, is it possible to share the information on how to implement it? Regards, Vish ... View more

Hi, I have a customer who is using ArcGIS for Windows Mobile on HP tablet with Atom processor running Windows 8. Customer is complaining that ArcGIS Mobile's keyboard being too slow on this hardware. When user is editing the textual field, there is a 1-3 seconds delay between user pressing a key using stylus and the value appearing in the text box. If user uses Windows 8 provided keyboard, there is hardly any delay. Anyone knows why this behaviour and if ArcGIS Mobile keyboard can be disabled permanently? Thanks, Vish ... View more

Hi all, I have a requirement that needs custom extension for ArcGIS for Windows Mobile on Windows 8. To use some of the third party and Windows SDK tools, I need to target my custom extension on DotNet framework 4.5. However, it seems that ArcGIS Mobile Project Centre does not identify customisations with target framework other than 3.5. Is it expected or am I doing something wrong? Regards, Vish ... View more

Hi all, I am having a little problem with a custom camera page I am having to develop in ArcGIS for Windows Mobile. The reason for custom camera page is, out of the box ArcGIS for Windows Mobile 10.1.1 does not provide user with option to chage camera resolution settings. In the code I am using following lines; ESRI.ArcGIS.Mobile.Client.WebCam.CameraService.DefaultCamera.CaptureHeight = 768; ESRI.ArcGIS.Mobile.Client.WebCam.CameraService.DefaultCamera.CaptureWidth = 1024; System.Drawing.Bitmap image = ESRI.ArcGIS.Mobile.Client.WebCam.CameraService.DefaultCamera.GetCurrentImage(); image.Save(System.IO.Path.GetTempFileName(), image.RawFormat); However, the code above falls over with MemoryAccessViolation, a very low level error. Even Try Catch does not seem to capture it. In debug mode, error sometimes happens at GetCurrentImage, sometimes at image.Save and sometimes after. I have tried all sorts of things, such as cloning Bitmap, saving it MemoryStream first and then saving to FileStream, adding Thread.Sleep, boxing the disposable objects with "using" etc. But one of the calls that involve Bitmap or Stream objects, falls over with AccessViolation. Any idea why this is happening. Out of the box Camera button works fine and I can see JPG created in %TEMP% folder as well as attachment added. Just they are very low resolution images. Any help is much appreciated. My project goes live in two weeks time. Cheers, Vish PS: Someone else had started a similar thread but no answer was provided. ... View more

Hi, I have a customer who is using ArcGIS for Windows Mobile to perform survey of assets. The part of the survey workflow is to take photos(s) of the asset while collecting/editing. The HP tablet client is using is running Windows 8 and is capable of taking high resolution photos. However, default camera used by the mobile app creates very low resolution images (< 16kb) and is very grainy. This is not acceptable to the client. I cannot find any way to change the settings of camera in terms of resolution etc. Does anyone know where this should be adjusted? Taking the picture outside of the mobile app and then attach it is not acceptable workflow to the client. Surveyors tend to attach wrong photos.  Thanks, Vish ... View more

Hello all, I have a requirement to customise Feature List menu and provide some additional options based type of feature. It seems that there is only a static event handler called FeatureListBox.CreatingFeatureListBoxMenuItems. Configuring menus using this event handler applies the changes to all features in the list. There could be different feature types in the list. e.g. when user runs "Identify" task, it can put a Pole and a Transformer into the FeatureList. I want to customise the menu based on type of feature selected. E.g. if a selected feature is "Pole", I want to replace standard "Edit" menu with custom EditAttributePage to capture pole attachments. I can see that FeatureListBox object has SelectedFeature property which seem to be set to current feature selected in the list. Is there any event handler for selection changed, like FeatureListBox.SelectedFeatureChanged? Or is there any other way? I tried FeatureListBox.CreatingMenuItems but this event never fires. Any help is much appreciated. Cheers, Vish ... View more

Hi, I am implementing an ArcGIS for Windows Mobile solution for a telecom client to do survey of Communcation Pits and equipment. The Pit feature class being surveyed has about 30 attributes, some are domain bound. However, many attributes are conditional attributes and need to be set only if some attribute has a specific value. I tried hiding/showing attributes in standard Edit Attributes page but customer wants wizard like interface where by additional attribute edit form pops up when certain value is set. E.g. in the Attribute Edit form, if user clicks "Yes" for "Is Hazardous Pit" attribute with YesNo domain, a new edit attribute page should pop-up showing hazard specific attributes for the Pit being edited. I am trying to add a new  EditFeatureAttributesPage class, set required attributes using EditFeatureAttributesViewModel and then transition the page to this new page. However, I cannot find approriate event handler to launch this EditFeatureAttributesPage. I tried DataColumnFeatureAttribute.PropertyChanged but it does not launch custom Edit Attribute page. Am I missing something? I must admit here I am new to Mobile SDK. So any help is much appreciated. Cheers, Vish ... View more

Hi, I have some vector datasets in Microstation DGN v7 file format. I added these DGN files in ArcMap as layers and they are displayed correctly with symbology based thematic etc. However, when I try to publish this map as ArcGIS for Server Map Service, I get "Layer type is not supported" critical error for all map layers that are DGN files. Does ArcGIS for Server support DGN files? If not, is there any documentation on which data types are supported by ArcGIS for Server. I thought everything that ArcMap supports can be published to ArcGIS Server. Thanks, Vish ... View more
