How to avoid system lock while running Windows Based Application - SaranKumarV - 12-13-2010

HI All,

We have an Windows based application which we are planning to run on nightly builds, Problem is when we run the script the system gets locked for every 10 min . Is there any workaround to keep system unlocked when running windows based applications.

Regards,

Hi Saran,

Turn off the password protected screensaver if it is on and also check if there is any setting to lock the computer automatically if left idle.

Hi Saran,

We can handle this... not an issue.

If you're able to download "Caffeine 1.4"... It's a small software(in KB's) available on website, you can run this on system to disable the automatic locking on your system. It is freeware so you can download in your company and use, not a problem.

still if your company strictly blocks such type of softwares.

you can handle through scripting...

Develop one VBScript file to run in background.
I'm not giving exact code here, just logic
Logic is :
1.send expectation time to keep your system desktop active.
2.take present time and sent time (eg: in hrs),
3.compare both of them and enter into loop
4.make wscript to sleep for some time like (less than automatic lock time)
5.press any lockkey (numkey, scrollkey) twice

it repeats step 3... till the sent hrs completed.

once it reaches the time, it will not enter into loop to sleep and press lockkeys.

It might locks after some time.

If you're not satisfy let me know.

Hi Saran,

Code:
Create .vbs file with the follwing code:

    Const DELAY_MINUTES = 10

    Wscript.Sleep DELAY_MINUTES * 60000

    Do

      CreateObject("Wscript.Shell").SendKeys "+"

      Wscript.Sleep DELAY_MINUTES * 60000

    Loop

Then using this .vbs create a task in the task scheduler.

Create a VBS file, Copy below code and paste it.

Code:
Const micVoid = 0

Const micByte = 26

Const micLong = 3

Const KEYEVENTF_KEYUP = &H2

Set Extern = CreateObject("Mercury.ExternObj")

extern.Declare micVoid, "keybd_event", "user32", "keybd_event", micByte, micbyte, miclong, micLong

Extern.Declare micVoid, "Sleep", "kernel32", "Sleep", micLong

While True

  extern.keybd_event 0, 0, KEYEVENTF_KEYDOWN, 0

  Extern.Sleep 20000

Wend

Save it, and double click on it, it will work

Just Down load the Attached Zip file Extract it,
Execute the extracted VBS file into your system (VBS Execution: Double click on the VBS icon)

It will avoiding you system lock issues.

Hi SaranKumar,

Please follow the below instructions:

Create a simple vbs file having code to press numlock key and run that vbs file
Edit one registry key “DisableLockWorkstation =1” to disable locking
