Scanning Lansweeper Service (on this machine).Įrror: Socket exception ConnectionReset: An existing connection was forcibly closed by the remote hostĮrror: The underlying connection was closed: An unexpected error occurred on a send.ĭescription: Microsoft Windows CE Version 7.0 (Build 2864) MC92N0G (data from all units merges to single asset) Below are the scan results from each device type. We have some other devices (not MC92N0G devices) with Windows CE that are identified by Lansweeper as unique assets.
SNMP scans are successful on these units and the MAC address is identified. Note: This article is written by Bruce Eitman, and is posted to the Embedded101 site with Bruce’s permission.We have some Zebra hand held scanners, MC92N0G, with Windows Embedded Compact 7 (CE 7) as the operating system that Lansweeper is merging scan data from all units into a single asset. You can use this while editing the registry or setting things up in the Control Panel to save your settings. On the other hand, suspending the system is a handy way to persist the registry when using an application, like the control panel applets, that don’t call RegFlushKey().Ī handy application to have in your tool bag is a simple application that calls RegFlushKey(). If the registry has already been persisted, then the data on disk does not need to be updated when the system suspends. So if it is important to quickly suspend, then your application must call RegFlushKey() when writing to the registry. If your system is using hive based registry, it will persist any registry changes when the system suspends. The application should call RegFlushKey() after writing a set of registry values rather than after each write because it is more efficient to call it after writing a set of values. It can be passed one of the predefined keys like HKEY_LOCAL_MACHINE, HKEY_CURRENT_USER or the key that was being used to write to the registry. RegFlushKey() takes one parameter a handle to a registry key. Your application should request that the registry be persisted when appropriate by calling RegFlushKey(). The OEM can configure filesys to automatically persist the registry when changes are made, but this may not be set up so don’t rely on it unless you know that it is set up. Many Windows CE devices use flash memory to persist the registry, and flash memory is relatively slow so automatically persisting can come with a performance hit. It is up to you to request that the system persist the registry when needed. These provide the OS with a method for saving the registry to non-volatile storage. This method pre-dates the hive based registry that was introduced in Windows CE 4.0. WriteRegistryToOEM/ReadRegistryFromOEM – in this method, the OEM implements these two functions in the kernel to save and restore the registry. This is probably the only way that is still being implemented on devices today, primarily because it is easy to implement.Ģ. Hive based registry – in this method, the Filesys is set up with a non-volatile disk to save the registry. Microsoft provides two methods for the OEM to implement registry persistence:ġ. The good news is that many Windows CE devices do have a way to persist the registry. So your device may lose your registry settings. The decision is up to the OEM to implement a way to persist the registry.
Windows CE devices may or may not persist the registry when power is removed or through a hard reset.
