kandi X-RAY | grab Summary
This is my own, experimental, parallel version of grep so I can test various strategies to speed up access to large directory trees. On Flash storage or SSDs, you can easily outsmart common greps by up a factor of 8. grab uses the pcre library, so basically its equivalent to a grep -P -a. The -P is important, since Perl-Compatible Regular Expressions have different characteristics than basic regexes.

QUESTION
Most of my WordPress websites have a background image in the top fold. These images are the Largest Contentful Paint Element on the page and usually they get loaded last. Somewhere I read that 'Background images are last in line to be grabbed when a page is loaded'. Is it true?
Is it a good idea to use a place holder or image in the place of the background image and then change it later so that the LCP gets loaded quickly like below.
ANSWER
Answered 2021-May-14 at 01:42You don't want to use a placeholder image to prioritize your background images in situations like this, you want to use . That will tell the browser to start downloading the image as soon as possible.
Try adding the following code to the of your page, and then use your background image as normal. It should load much faster:

Sorry I don't show my variables or anything, tried to give information only pertaining to the questions. This 1 Sub is huge.
Currently my code allows a user to select multiple files, the files selected will be sorted in a specific format, then loaded into 2 different arrays. Currently loads Columns D:E into 1 array and Columns I:K into another array (from selected files QSResultFileWS
, and returns those arrays to my destination FormattingWS

QUESTION
I've created a simple VBA interface to connect Excel to a MySQL DB. The VBA part acts as a preview of data for the user to choose what item he wants to import to the Excel sheet.
Until now I've work with a very complete set of data, but I got to a Table which (because of the nature of the items) some fields are NULL.
Now every time I try to check the values in the VBA I get the Run-time error 13 Type mismatch in the listview component. At first I though it was a field with DECIMAL typing, but after changing it to a DOUBLE (for testing) the problem persisted, and it was until I notice that if only checks columns with no NULL value, the problem disappears. Off course I can't omit this values.
I tried some .Tostring functions but with no success. And I failed to implement a IF to check for NULL in the obj.
This is my code:

I am using Visual Studio with asp.net, vb.net, and webforms.
My issue is that I need to get the user's textbox input from my dynamically generated textboxes.

QUESTION
I'm trying to setup a single sign on system using WordPress and Azure AD B2C. I’ve got it working, however, I’m trying to find a way that would allow me to link to the registration page on Azure directly. Currently, I’m only able to generate a link to the Sign-on page. I’d like to find a way to generate a link to the Sign-up page. I’m using the Sign up and sign in User Flow, and due to the way the WordPress Plugin was developed, I can’t use more than this one user flow.
I've written a script that looks at the source of the Sign on page, grabs the sign-up link and displays it, but that approach doesn’t work.
I need to be able to display both Sign-on and Sign-up links on my website.
Can anyone point me in the right direction to where and how I could achieve this?
Thanks!
...ANSWER
Answered 2021-Jun-14 at 19:05With one user flow, it's not possible to achieve this. You cannot link to the Sign Up portion of the combined flow. You have to go through the Sign In page to reach the Sign Up page.
QUESTION
I am in the process of updating my app and with Apple changing the Privacy requirements(I do like this), I believe I need to add App tracking permissions into my app. This is because I use a webview that goes to a third party website that grabs the device IP address and puts a cookie in the view. I am struggling with how to do this in Uno. I know it uses the Xamarin platform underneath- but I am not really understanding how to do this. There are no ads anywhere in the app. I have only been able to find a few examples- so what I am putting below is based off of them.
I see that I need to add NSUserTrackingUsageDescription to my info.plist. I see that I need to use AttTrackingManager. So- first- how do I import AttTrackingManager into my project in Visual Studio? I checked in Nuget and did not see it. From what I can tell- I need to check for the value in my OnLoaded, and depending on the value I need to either zero out the device ID or do nothing. Also- do I need to check this value anytime my app accesses the webview- User goes to a different page in the app and comes back to the webview(I would think I need to check it)?
Are my statements above correct? Is the best way to implement the parts in the code using something like this:
...ANSWER
Answered 2021-Jun-14 at 14:43Your approach seems sound. Let me clarify some of your interrogations.
1- You are looking for a nuget but you don't need to. ATTrackingManager is part of the iOS SDK (in the AppTrackingTransparency
namespace), as long as you target iOS14.5 as a compilation target you will have access to it. The Xamarin.iOS bits are built-in VisualStudio, so just make sure your version is high enough.
2- You need to add a NSUserTrackingUsageDescription
in info.plist as you mentioned. This will be displayed in the popup.
3- In your code, to prompt the user with the native popup you need something like this.
