QUESTION
TLDR; Checking variable before using it in a anonymous function still TS warns variable possibly undefined
In the below code example variable baseDirId
is checked if undefined then passed to array.map function but TS warns baseDirId
can be undefined.
ANSWER
Answered 2021-Apr-18 at 12:02TypeScript does not check types and even change types at runtime, so baseDirId
type would always is string | undefined
unless you do narrow types or something else for type, so there are many options you can try.
1. Use default

I'm trying to parse weight
, depth
and height
from the following string using regex '84" w x 39" d x 37" h'
. I got success while scooping out weight
and depth
for it. However, I could not scrape the height
in the right way. I know the patterns I've used might be very weak but it works for the first two fields.
I've tried with:

Answered 2021-Jan-18 at 20:02w, d, and h are not in same order, which makes one-line find all a bit hard, but probably still doable.
But for now, let us stick with one line for each:
QUESTION
I'm new to Golang and have been doing alright but I have a strange issue that I have not encountered before when using fmt. This strange behavior is when I'm printing a string. At the end of the string (which has sub-strings) it is also printing out what appears to be the len() of each string although the number don't add up. Can anyone explain why this is happening and how to stop it?
Any help is greatly appreciated
Here is the code:

are the number of bytes written by those three Printf
calls, and the three numbers printed are those numbers.

Alright, i am using Simple HTML DOM (https://simplehtmldom.sourceforge.io/) to get some data from a page.
The data i would like to get are these selector options:
...ANSWER
Answered 2020-Aug-26 at 15:32Your code is correct but data is not there.
Please look at source of your page. Not in inspector but just raw source that is coming to your browser at first. In chrome you can do this with ctrl + u
on windows (view source). This way you will see that page that you are requesting doesn't contain any values in html select
item when it comes to the browser. This values are populated later with javascript functions but unfortunately Simple HTML DOM doesn't run javascript so scraping it is not possible with this library.
You need to look for something that can run javascript. Probably some headless browser would be an option. If you need to stick with PHP you can start by looking here: https://github.com/symfony/panther or here: https://github.com/php-webdriver/php-webdriver

QUESTION
I am doing an exercise to get to know the shared pointer and weak pointer.
So the example is with cyclic dependence of shared_ptr and how could I solve the problem with weak_ptr.
I want to initialize the root->left->parent to root and the same for right node but it is giving me segmentational fault.
Does anybody know something about this problem, how should I write and initialize it?
Here is my code.
Just to know, my first exercise was to do it all with only shared pointer, but after that to change parent to be the weak_ptr, so that's why there are commented lines
Thanks in advance
...ANSWER
Answered 2020-Aug-14 at 11:34// if (parent != nullptr) pStr = parent->name;
pStr = parent.lock()->name;

QUESTION
I am currently facing a problem with the "System.Net.Http" assembly that gives me a real headache.
Before going any further, I searched for hours on the Web reading and trying the solutions mentioned in several posts, like the following ones:
- Strange issue with System.Net.Http 4.2.0.0 not found
- https://github.com/dotnet/runtime/issues/26131
- Could not load file or assembly 'System.Net.Http, Version=4.2.0.0, Culture=neutral on IIS
- https://github.com/Microsoft/dotnet/blob/master/releases/net472/KnownIssues/613745%20-%20Single-name%20references%20are%20removed%20by%20the%20SDK%20when%20targeting%204.7.2.md
- Could not load file or assembly 'System.Net.Http
- https://www.reddit.com/r/csharp/comments/99zuzs/systemnethttp_is_driving_me_insane/
- Could not load file or assembly "System.Net.Http, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"
Obviously, I am missing something, because I can't solve this problem.
Basically, I have a Solution composed of several projects all targeting .NET Framework 4.7.2. One of the is a simple console application and the others are class library project. One of them contains references to SharePoint CSOM and Office Dev PnP.
However, each time the following line is hit...
