I am working on CE.NET 4.2 with AGX. When I tried to set the time to 4/3/2005 1:59:45 or 10/30/2005 1:59:45, a daylight saving confirmation dialog will come up after 15 sec. I noticed that there is a subkey in the registry [HKLM\Software\Microsoft\Clock\ShowDSTUI]. However, I tried to set the value to 0 or to delete the value but the value 1 returned after reboot and changing new time.
Please kindly advise how I can disable the confirmation dialog for daylight saving times. |

Ken,
You can disable the confirmation dialog by adding the entry below into your adsload.reg file. If you add this to the end of the file, make sure there is a carriage return at the end of the last line.
You will then put the adsload.reg onto your CF card and reflash your AGX with the DIP switch set to 1,3 and 4 ON and 2 OFF.
Add this to your adsload.reg:
[HKEY_LOCAL_MACHINE\Software\Microsoft\Clock]
"AutoDST"=dword:1
"ShowDSTUI"=dword:0

| Thanks for your response. We have devices out in the field. So we would like to do this by only updating the software or running a script. Would you advise if there is any way to do this programmatically? I tried to change the registry (as in the first message above) but failed. |

You can do this programmatically. In your app change the key to the settings you want, use RegFlushKey() to persist the registry and the new settings will take effect on reboot.
Take a look at topic 843 for more about persisting the registry and RegFlushKey(). |

I simulated the RegFlushKey by using the applet "ADS Persistent Registry" to save the registry. But after I rebooted the device and changed the date/time, the value for ShowDSTUI restored to 1 automatically. Any idea?

If you use regedit to change the settings, modifying the key value will not work. Instead you should delete the ShowDSTUI and add a new one with the same name ShowDSTUI and the appropriate value. Then you can use "ADS Persistent Registry". After the reboot you should see the new settings.
I just verified this minutes ago. Hope this helps. |

| Thank you for your patience. The problem was still there. After I did what you said, I saw the new setting after reboot but then when I tried to modify the clock, say, setting one day ahead, the value of ShowDSTUI changed back to 1! |

| I have done more experiments. It seems the value of ShowDSTUI will set to 1 only from changing the time through the Date/Time Properties. I tried to use P/Invoke to change the time and the value remained 0. I guess my problem has been solved. Thanks hchin for the contribution. |
