vbscript - Recursive Function return value in vb script -


please see below function fnwaitcheckfinalstatus if else part executed in below code value return function fnwaitcheckfinalstatus coming blank because function called recursively fnwaitcheckfinalstatus.

is there way return value of fnwaitcheckfinalstatus after exit function function should exit state.

how can make possible , pointers on this.

function fnwaitcheckfinalstatus(objstatusbar)      dim blnretvalue : blnretvalue = true     dim : i=0       if objstatusbar.exist         strvalue=objstatusbar.getroproperty("text")                       wait 10             strvalue=objstatusbar.getroproperty("text")         loop while strvalue = "task started"      end if      strvalue1=objstatusbar.getroproperty("text")     if strvalue1="task executed successfully"         blnretvalue1=true         fnwaitcheckfinalstatus = blnretvalue1         exit function     elseif strvalue1="task execution failed"         blnretvalue1=false         fnwaitcheckfinalstatus = blnretvalue1         exit function     else         call fnwaitcheckfinalstatus(objstatusbar)     end if    end function

consider "pass-through"ing function result if return recursion, in code (note line !!! comment):

function fnwaitcheckfinalstatus(objstatusbar)      dim : i=0       if objstatusbar.exist         strvalue=objstatusbar.getroproperty("text")                       wait 10             strvalue=objstatusbar.getroproperty("text")         loop while strvalue = "task started"      end if      strvalue1=objstatusbar.getroproperty("text")     if strvalue1="task executed successfully"         fnwaitcheckfinalstatus = true     elseif strvalue1="task execution failed"         fnwaitcheckfinalstatus = false     else         fnwaitcheckfinalstatus=fnwaitcheckfinalstatus(objstatusbar) ' !!!     end if    end function

also, eliminated result buffer variable. don´t need it, can scratch it.

also, i'd avoid exit function in case keep code simpler (one entry point, 1 exit point), eliminated that, too.

generally speaking, there no obvious reason using recursion here since pass same argument receive, recursive call same caller scope. use loop instead.

python - Django-cities exits with "killed" -

i trying install django-cities on server 500mb ram. whenever run: manage.py cities the system exits saying killed. trying run: manage.py cities --import=country --force worked, guessing matter of running out of memory. to bypass, tried refer package local copy of cities' data file. still didn't work. any ideas on how can migrate data without having increase memory on server? based on suggestion comments, solved setting temporary swap file. if unfamiliar it, can follow these steps: set swap file touch /var/swap.img chmod 600 /var/swap.img set swap file size cd /var dd if=/dev/zero of=/var/swap.img bs=1024k count=1000 this create 1gb swap file. prepare disk image mkswap /var/swap.img activate swap memory swapon /var/swap.img once done, can turn off swap image: swapoff /var/swap.img more information on virtual memory , swap files can found here: https://www.digitalocean.com/community/tutorials/how-to-configure-virtual-me...
