QUESTION
Could you please clear up a question for me regarding pointer vs object in C++. I have the below code that has a class called "person" and a list that allows for 100 objects of that class type.
...ANSWER
Answered 2021-May-30 at 20:27basically the first case works like this: you have an array of objects. To access the object fields and methods you use . operator.
In the second case you have an array of pointers to an object. Pointer is just a memory address, that points to an object of some type. In your case, this is an array of pointers to class person. By default, these pointers are invalid; you have to set them to the address of some existing object. new creates an object on the heap, and returns you an address of that object. In order to access the value behind the pointer, you have to de-reference it. The syntax is this:

If it is still not clear please let me know.
...ANSWER
Answered 2021-Apr-13 at 13:15You can do that with formula to cross-check both files.
First sheet:
Customer Name (A1) Invoice Number (B1) Key (C1) Find_Missing - formula - (D1) Carpenter (A2) 101 (B2) =A2&B2 =Iferror(Index(Sheet2!C:C;Match(A2&B2;Sheet2!C:C;0));"Not Found") Painter (A3) 102 (B3) =A3&B3 =Iferror(Index(Sheet2!C:C;Match(A3&B3;Sheet2!C:C;0));"Not Found") Courier (A4) 103 (B4) =A4&B4 =Iferror(Index(Sheet2!C:C;Match(A4&B4;Sheet2!C:C;0));"Not Found")Second sheet:
Customer Name (A1) Invoice Number (B1) Key (C1) Find_Missing - formula - (D1) Carpenter (A2) 101 (B2) =A2&B2 =Iferror(Index(Sheet1!C:C;Match(A2&B2;Sheet1!C:C;0));"Not Found") Courier (A3) 103 (B3) =A3&B3 =Iferror(Index(Sheet1!C:C;Match(A3&B3;Sheet1!C:C;0));"Not Found") Welder (A4) 104 (B4) =A4&B4 =Iferror(Index(Sheet1!C:C;Match(A4&B4;Sheet1!C:C;0));"Not Found")QUESTION

QUESTION
I am testing gke ingress to route traffic to two different services. My deployment consists of a basic web container that deploys a blue web page default and a green web page. I am able to get a response back Essentially the "/" works with either blue or green deployment. But when i go to http:///green i get a 404 response. I have tested the same with "/" as green deployment and it displays a green web page. But if i go http:///blue it results in a 404 response,
I have verified my containers are working properly by attaching a load balancer directly to them. I am following this how to guide in gke to setup a similar environment. GKE Ingress How to guide
Any help on what i am missing would greatly help me understand better what is going on and why my gke load balancer is unable to route traffic.
green deployment file
...ANSWER
Answered 2021-Jan-17 at 19:47I found the problem is with gke ingress controller. Gke ingress controller doesn't provide rewrite-target to /. I am serving my green and blue web pages from the webroot. GKE ingress controller is forwarding the requested URL http://34.95.121.24/green to http://{backend }/green. There is no page hosted on http://{backend }/green as my default page is hosted on http://{backend}/.
There are two solutions to the problem.
- Use nginx-ingress controller with annotation to rewrite-target set to /.

QUESTION
TLDR: How to force widget state to reinitialize
I have a List of nested ExpansionTiles with a PageStorageKey. Each Tile has an attribute that can be selected/deselected. Selected items are added to a list and returned back to the calling page. This functionality is working well. The problem is that when I come back to the Selection page it is still holding the state of items previously selected. After navigating (pop) back to the home page I would like for all the state data associated with the Selection page to be reset or deleted and reinitialized.
I added deactivate() and dispose() methods but it's still holding on to the state. I also added a unique key but that didn't help.
[home page][1]
...ANSWER
Answered 2020-Aug-07 at 12:21Basically the issue is that you are using a global variable for storing Occupation details. And every time you are using it directly. Either you can create its copy when its used or you will have to reset the selection values. This solution is based on resetting the occSelected value.

Answered 2020-May-13 at 10:26The problem is that the output_field is a parameter you pass to the .annotate(..) part. You can use an ExpressionWrapper [Django-doc] to interpret the type of the value, or Cast [Django-doc] to do conversions:

Install welder
Install dependencies Welder requires expect, rsync and ruby. Ruby is used mainly as a convenient way to parse YAML configuration files. Optionally, if you'd like to use the templating feature, you need to install liquid gem: $ gem install liquid
Check out welder into ~/Code/welder (or whatever location you prefer): $ git clone https://github.com/pch/welder.git ~/Code/welder
Add ~/Code/welder/bin to your $PATH for access to the welder command-line utility. $ echo 'export PATH="$PATH:$HOME/Code/welder/bin"' >> ~/.bash_profile Ubuntu Desktop note: Modify your ~/.bashrc instead of ~/.bash_profile. Zsh note: Modify your ~/.zshrc file instead of ~/.bash_profile.
Restart your shell so that PATH changes take effect. (Opening a new terminal tab will usually do it.) Now check if welder was set up: $ which welder /Users/my-user/Code/welder/bin/welder
