"Automatically adjust clock for daylight saving changes"

[=?Utf-8?B?Qm9iQWNoZ2lsbA==?=]

Is there a way to know if this is set to true on the Windows Time Zone tab?

Through the registry:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\TimeZoneInformation

Value: DisableAutoDaylightTimeSet

A value of 1 means the setting is disabled otherwise the value didn't
exist or is 0.

I tried this see below but got this Error
Unhandled Win32 Exception
Imports System
Imports Microsoft.Win32

Put this in the Form1_Load...

MsgBox("DisableAutoDaylightTimeSet = " +
Registry.LocalMachine.OpenSubKey("SYSTEM\CurrentCo ntrolSet\Control\TimeZoneInformation").GetValue("D isableAutoDaylightTimeSet"))

The syntax is correct and doesn't cause an Win32 Exception here. I
would not say that the code will only working on WinXP SP2, it was the
only system I tried that. Maybe it would be easier, if you tell us,
what is your system configuration, where you get the Exception.

Normally the code shouldn't throw an Win32 Exception, only an
NullReference Exception, when the Value didn't exists. Maybe better,
if you use a default value:

MsgBox("DisableAutoDaylightTimeSet = " &
Registry.LocalMachine.OpenSubKey( _
"SYSTEM\CurrentControlSet\Control\TimeZoneInformat ion" _
).GetValue("DisableAutoDaylightTimeSet", 0).ToString)

WFM.

Works for me.
