Use MailItem.Recipients collection.
See #1 and check for each recipient's Recipient.Type property equal olCC ( =2)
Of course - set the MailItem.Categpries property. Don't forget to call MailItem.Save
Use the MailItem.SenderEmailAddress. For the sent on behalf of address, read the PR_SENT_REPRESENTING_EMAIL_ADDRESS MAPI property. Access it using MailItem.PropertyAccessor.GetProperty("http://schemas.microsoft.com/mapi/proptag/0x0065001F")

The problem is that your CSS selectors include parentheses () and dollar signs $. These symbols already have a special meaning. See:

() - Are parentheses allowed in CSS selectors?
$ - [attribute$=value] Selector

You can escape these characters using a backslash \.

QUESTION

Does opening a file in a child process create a separate entry in the system open file table in the kernel?

Asked 2021-Jun-15 at 23:17

I understand that after calling fork() the child process inherits the per-process file descriptor table of its parent (pointing to the same system-wide open file tables). Hence, when opening a file in a parent process and then calling fork(), both the child and parent can write to that file without overwriting one another's output (due to a shared offset in the open-file table entry).

However, suppose that, we call open() on some file after a fork (in both the parent and the child). Will this create a separate entries in the system-wide open file table, with a separate set of offsets and read-write permission flags for the child (despite the fact that it's technically the same file)? I've tried looking this up and I don't seem to be able to find a clear answer.

I'm asking this mainly since I was playing around with writing to files, and it seems like only one the outputs of the parent and child ends up in the file in the aforementioned situation. This seemed to imply that there are separate entries in the open file table for the two separate open calls, and hence separate offsets, so the slower process overwrites the output of the other process.

To illustrate this, consider the following code:

ANSWER

Answered 2021-May-03 at 20:22

There is a difference between a file and a file descriptor (FD).

All processes share the same files. They don't necessarily have access to the same files, and a file is not its name, either; two different processes which open the same name might not actually open the same file, for example if the first file were renamed or unlinked and a new file were associated with the name. But if they do open the same file, it's necessarily shared, and changes will be mutually visible.

But a file descriptor is not a file. It refers to a file (not a filename, see above), but it also contains other information, including a file position used for and updated by calls to read and write. (You can use "positioned" read and write, pread and pwrite, if you don't want to use the position in the FD.) File descriptors are shared between parent and child processes, and so the file position in the FD is also shared.

Another thing stored in the file descriptor (in the kernel, where user processes can't get at it) is the list of permitted actions (on Unix, read, write, and/or execute, and possibly others). Permissions are stored in the file directory, not in the file itself, and the requested permissions are copied into the file descriptor when the file is opened (if the permissions are available.) It's possible for a child process to have a different user or group than the parent, particularly if the parent is started with augmented permissions but drops them before spawning the child. A file descriptor for a file opened in this manner still has the same permissions uf it is shared with a child, even if the child would itself be able to open the file.

QUESTION

How to make an axios get request on page load, then render a am4chart with that data?

Asked 2021-Jun-15 at 22:40

I have the wackiest bug. Like....the wackiest! If any of ya'll want to put eyes on this, awesomesauce! I really appriciate it! I am creating a survey with REACT, Redux, SQL, HML, Material-ui, and CSS.

I've created a graph of information with am4charts using data from a database. Everything is working and will show up on the page......but not on page load. What I am seeing in my console is that the page will load, it fires off my get request but doesn't return with the data fast enough (I think). By the time that the get request loads, my graph has populated with no data.

Here is the code that I have for the page that I am rendering. What is really odd is that, once my code has run, I can cut a line of code (I've been using a console log). And then the graph will render and load.

QUESTION

Good way to switch between 2 versions of the same dependency in package.json?

Asked 2021-Jun-15 at 21:43

Turns out you can't have comments in JSON files, and it's a bit awkward to have people refer to some documentation telling them what line to copy/paste in and where in order to achieve this.

I think I can make a python script to copy/paste in one of two package.json files depending on what flags they pass in, but that feels overcomplicated.

I think I can include both dependencies (under different names) but that would create a requirement for both to be available, which is not good either.

Looking for ideas/thoughts on a good way to accomplish this. I have a release and dev version of the same dependency and I often need to swap between the two. Would like to improve the workflow beyond just having a notepad on the side with the two lines pasted in it...

React Router Link changes URL but doesn't render Component - Rest Countries API

Asked 2021-Jun-15 at 17:07

I am building an app following the Rest Countries API challenge from frontendmentor (https://www.frontendmentor.io/challenges/rest-countries-api-with-color-theme-switcher-5cacc469fec04111f7b848ca). I have run into a problem. When clicking on the router link in countryDetail.js, the url changes but the component doesn't get re-rendered unless the page is refreshed.

CountryDetails.js

...

ANSWER

Answered 2021-Jun-15 at 17:07

Issue

The issue seems to be that you are already on the "/country/:name" path and are clicking to visit another country. The router correctly updates the URL in the address bar, but because CountryDetail is already mounted it neglects to recompute the item and allCountries state. This is because the useEffect hook only runs once when the component mounts.

Solution

The name param (match.params.name) is actually a dependency for the GET requests, it should be added to the useEffect hook's dependency array.
