While string check?

[zandztrom]

Hi,

I'm totally new to loops and iterations and stuff so I need some help.

I use _NTservices to stop and start SQLServer and want to check that it's properly stopped before it is started again and if it takes too long it should time out.

How can I do this in an easy way? Should I use a while loop? In that case how is it used to check against a string such as "stopped".

Start with something like this:

While 1

$Returned_String=Service_State()

    Select
        
    Case $Returned_String="Stopped"
;Do Somehting
    
    Case $Returned_String="Started"
;Do Somehting
    
    Case Else
    
    EndSelect


Wend


Func Service_State()

;Here you would put in the code that you would use to check the state of a service and make it equal to $String

;And then return the string using "return $String".

EndFunc

Good Luck.

How are you doing the start/stop of services? NET.exe, WMI, ...?

@DjDeep00! Thanks for your quick help I'll try that...

@ PsaltyDS. I manage services by using the includes:

NTServices.au3

http://www.autoitscript.com/forum/index.php?showtopic=22165

or

ServiceControl.au3

http://www.autoitscript.com/forum/index.php?showtopic=6487

Would be great to have a equivalence to RunWait() for services ex _StartSvcWait() etc.

You can code your own easily with TimerInit/TimerDiff plus the _ServiceStatus() function.

Hehe, well as you can see from my former question I'm not really a code wizard.

Me either, but this is a shot at how I would do it (not tested):

#include <_NTServices.au3>

; ---------------------------------------------
; Function:     _ServiceStartWait()
; Purpose:  Start a service and wait for service status to be "Running"
; Call with:    _ServiceWait($v_ServiceName, $v_ComputerName = "", $i_Timeout)

;           $v_ComputerName (optional) = computer to operate on, default is local
;           $i_Timeout (optional) = timeout in seconds, default 0 = never timeout
; On success returns non-zero
; On failure of the service start returns 0 and sets @error and @extended
; On timeout returns 0 and @error = -1

;           name seen in the GUI manager.  Use _ToInternalServiceName() to translate

I had another idea, and combined the two into one function: _ServiceStatusWait(), which will wait for any given status, i.e. "Running" or "Stopped".
