Event viewer

[nickzlapeor]

Is there a way to extract info from the Event Viewer, like the last Shutdown time and date. The registry in Win 8 shows the last Restart time instead of Shutdown. I know the Registry can show Shutdown time, but -> 1. Only UTC format, 2. How to extract it from Registry to be used with Rainmeter. Any help?

I am not sure, how to extract from Event Viewer, but you can always save it in rainmeter itself the time and parse it back.

Sorry I'm a noob, I didn't get what and how can it be done.

I mean you have something running in the backround of your skin which stores the current time, or time interval: Like a Lua script. This will save the time in variable fields like

lastHour = xx
lastMin = xx
lastSec = xx

and then you have the data avaiable on next startup

Code: Select all

[mHour]
Meter = String
Text = %lastHour%

Didn't get it. Won't the time change on startup?

I know nothing about Lua so detailed help would be appreciated, if possible. Many thanks for replying though!

It's stored in HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Windows\ but the value of ShutdownTime is in Binary mode and I've no idea if Rainmeter supports this.

Need expert help!

Well I've checked the online manual of Rainmeter and just saw that Registry measure doesn't support REG_BINARY.

I don't know about Lua but you can simply use this VBScript to read the value in that key and export it to a text file and then parse it using the WebParser measure.

Copy the below code and save it in a new file with .vbs extension.

Code: Select all

strValueName = "HKLM\SYSTEM\CurrentControlSet\Control\Windows\" & "ShutdownTime"
Set oShell = CreateObject("WScript.Shell")
Ar = oShell.RegRead(strValueName)
Term = Ar(7)*(2^56) + Ar(6)*(2^48) + Ar(5)*(2^40) + Ar(4)*(2^32) + Ar(3)*(2^24) + Ar(2)*(2^16) + Ar(1)*(2^8) + Ar(0)
Days = Term/(1E7*86400)
ShutTime = CDate(DateSerial(1601, 1, 1) + Days) & " UTC"
TextPath = "D:\ShutDownText.txt"
Set ShutText = CreateObject("Scripting.FileSystemObject").OpenTextFile(TextPath,2 ,True)
ShutText.WriteLine ShutTime
ShutText.Close
Set ShutText = Nothing

I dont think you can access the Registry from Lua, but you can write to and read from files. Date/Times have Integer representation which can be easily transformed, but I guess many roads lead to rome!
