Auto Updates using DUA

[Guest]

Hi All,

Anybody please try to give answers for the following points.
If we use Device Update Agent (DUA) for auto updates on XPe device then can
we do the following:
1. Change the updates time by editing the script file during run-time (i.e.
we may provide a GUI to set the time of update on XPe device.)
2. Change the location of update source for e.g. the update location
previously set to a local folder on hard disk can be change to USB device
attached to USB port.
3. What is the condition for other applications running at the time of
providing the updates, whether we have to close those applications and run
update or can proceed as it is?
4. What are the limitations of types of updates that we can provide to XPe
device with this scheme?

Thanks & Regards
Roshan

The settings for DUA are basically in the registry so you should be able to
set these either in the script or within an application spawned by the script.
The only limitations I am aware of are if the file is "in-use" at the time.
You can try two options there (1) ask the user to close it (2) [especially
for system files] rename it, copy the new on, reboot and then delete the
renamed one. [see http://msdn2.microsoft.com/en-us/library/ms932939.aspx]
