I have downloaded the most recent UPD PCL6 driver from HP home page. Its version 7.0. We are using a solution call HP Access Control (16.8.1) which is a so called pull print solution. I created a queue on my Windows Server 2016 and created a port. The HP Access Control comes along with its own port monitor. I assigned the port to the queue and when I open the printer properties I get an error:

Function address 0x00007FFEB9E06402 caused a protection fault. (exception code 0xc0000005)

I have done this installation some time ago with the same version of HP Access Control and there all worked. Unfortunately I deleted that VM. But I believe I had an older version of UPD installed. Server operating system was also WS 2016.

I have in my project the following handler:

When I use PowerShell, I only get one (Workbook3) of several window titles (Workbook1, Workbook2, Workbook3), but I want to get the entire list of all open Excel books. I am trying to use the following code:

I wrote my std::common_type implementation:

Story: in my java code i have a few ScheduledFuture's that i need to run everyday on specific time (15:00 for example), the only available thing that i have is database, my current application and openshift with multiple pods. I can't move this code out of my application and must run it from there.

Problem: ScheduledFuture works on every pod, but i need to run it only once a day. I have a few ideas, but i don't know how to implement them.

Idea #1: Set environment variable to specific pod, then i will be able to check if this variable exists (and its value), read it and run schedule task if required. I know that i have a risk of hovered pods, but that's better not to run scheduled task at all than to run it multiple times.

Idea #2: Determine a leader pod somehow, this seems to be a bad idea in my case since it always have "split-brain" problem.

Idea #3 (a bit offtopic): Create my own synchronization algorithm thru database. To be fair, it's the simplest way to me since i'm a programmer and not SRE. I understand that this is not the best one tho.

Idea #4 (a bit offtopic): Just use quartz schedule library. I personally don't really like that and would prefer one of the first two ideas (if i will able to implement them), but at the moment it seems like my only valid choice.

UPD. May be you have some other suggestions or a warning that i shouldn't ever do that?

I am trying to make a function that should return NA of the same class as function's input. So, for example, myNA('abc') returns NA_character_, myNA(123L) - NA_integer_, etc.
I tried something like this:

I have been trying to update a record in the database in window form but each time I click the update button I get this error.

System.Data.Entity.Infrastructure.DbUpdateException: 'An error occurred while updating the entries. See the inner exception for details.' SqlException: Violation of PRIMARY KEY constraint 'PK_ad_gb_rsm'. Cannot insert duplicate key in object 'dbo.ad_gb_rsm'. The duplicate key value is (100001). The statement has been terminated.

Below is the LINQ code I am using

I can get this data with the following code. But it runs too slow:

I have a context and try to pass it to my children components:
