VBA code to consolidate data in one row from three rows Posted: 30 May 2021 08:11 AM PDT I have access data for all card numbers. Each card number have 3 entries in three rows. But I want data for each card number in one row. I have tried below code but output have 2 lines blank. Could you please suggest any alternate solution to get correct data in one row for every card number. Sub ConsolidateData() For i = 2 To 19 'for first row Sheet3.Range("A" & i) = Sheet2.Range("A" & i) Sheet3.Range("B" & i) = Sheet2.Range("B" & i) Sheet3.Range("C" & i) = Sheet2.Range("C" & i) Sheet3.Range("D" & i) = Sheet2.Range("D" & i) 'for second row i = i + 1 Sheet3.Range("E" & i - 1) = Sheet2.Range("B" & i) Sheet3.Range("F" & i - 1) = Sheet2.Range("C" & i) Sheet3.Range("G" & i - 1) = Sheet2.Range("D" & i) 'for 3rd row i = i + 1 Sheet3.Range("H" & i - 2) = Sheet2.Range("B" & i) Sheet3.Range("I" & i - 2) = Sheet2.Range("C" & i) Sheet3.Range("J" & i - 2) = Sheet2.Range("D" & i) Next i End Sub

Cut an area of a polygone Boost C++ Posted: 30 May 2021 08:11 AM PDT I'm trying to cut a part of a boost polygon. Basically i have a polygon boost::geometry::read_wkt("POLYGON((-2 -700,-2 -445,100 -455,100 645,1075 645,1075 -145,1300 -145,1300 -700))", b); And i want to cut a part of my polygon. For example, if i have this kind of polygon (in black), i would like to delete the red part I already tried to do something like that, boost::geometry::interior_rings(b).resize(1); append(b, tuple_list_of(200, 200)(200, 500)(600, 600)(500, 200)(200, 200), 0); But one line (or several) of my polygon disappear. I don't necessarily want to cut part of my polygon, I just want that part to no longer be part of the whole and not be detected by withinbecause i'm using Point p(x,y); bg::within(p, poly) And I'd like to put in some unverifiable areas. If anyone have an idea for this, thanks

Create shapes on canvas that can resized by dragging the corners and moved by dragging the shape - tkinter Posted: 30 May 2021 08:10 AM PDT Is there a way to create shapes on a canvas that can be resized by dragging the corners and moved by dragging the shape I know how to create it on a canvas by using .create_shapename but then I can't assign it to a variable (if I am wrong please correct me) Thanks!

Neo4j multiple level match query with condition Posted: 30 May 2021 08:10 AM PDT the query match (n)-[:friend*0..3]->(b) where n.salary >= 19999 and n.address="Paris" and b.salary >= 19999 and b.address="Paris" return distinct n.name order by n.name doesn't give me what I want: I'm trying to display all the names of the persons living in Paris for whom all of their friends for 3 level generations also live in Paris and also have a salary higher than 19999. The above query doesn't do it well, what am I doing wrong ? for example: if Buddy lives in Paris, earns +20k and all of his friends for 3 level generations also live in Paris and earn +20k then Buddy should be returned. Else he shouldn't be.

How do i inject ConstrainValidator? Posted: 30 May 2021 08:10 AM PDT Imagine i have an annotation A @Target({TYPE}) @Retention(RUNTIME) @Documented @Constraint(validatedBy = {Validator.class}) public @interface A { String value() default ""; String message() default "{javax.validation.constraints.form.customization.message}"; Class<?>[] groups() default {}; Class<? extends Payload>[] payload() default {}; } that has a Constraint Validator which is not an implementation of ConstraintValidator rather an extension of one public interface Validator extends ConstraintValidator<A, Entity> { } And then some implementation of Validator. Is there any way i can make it work with Spring, dependency injection and all that good stuff? Thank you

How to convert custom type definition file to npm type definition file Posted: 30 May 2021 08:10 AM PDT I have a custom module definition file for a dependency written in CoffeeScript in my typescript project. It looks like the following and works great: src/@types/dependency-name.d.ts declare module 'dependency-name' { import EventEmitter from 'eventemitter3'; /** * omitted */ interface ICable { new (channels: Record<string, ISubscription>): ICable; channels: Record<string, ISubscription>; channel: (name: string) => ISubscription | undefined; setChannel: (name: string, channel: ISubscription) => ISubscription; } export const Cable: ICable; } So I want to contribute to this project and submit a type definition file. What I tried is: Forked the original CoffeeScript project, Copied the above definition to index.d.ts Add the following line to pacakge.json: "typings": "index.d.ts", Installed forked repository in my typescript project for testing. However, it does not recognize the added index.d.ts file. Shows type definition is missing error. I've seen this post and guessed that the issue is this one: be written as external modules But I don't understand it. Can someone guide me to convert my custom typing (module augmentation, I guess?) to correct type definition file for package.json?

Anonymous array becomes undefined when accessed [duplicate] Posted: 30 May 2021 08:11 AM PDT Here's where my problem is: function applyConfig (conf) { Running = false ['points', 'pointsz', 'centroids', 'centroidsz'].forEach( f => console.log(f)) } The real functionality has been stripped and replaced with console.log() to narrow things down. The actual problem is that the line with the anonymous array throws either "Cannot read property 'forEach' of undefined" or "Cannot read property 'centroidsz' of undefined". I can't reproduce this minimally as the crux is the first line, Running = false. There is an animation loop going (yes, yet another k-means demo) contingent on this condition. The function in question is used in an event callback independent of the animation. If I remove that line, leaving the loop running, this works as expected. There is a simple "fix" which I don't like because I don't understand why it works where the other does not: function applyConfig (conf) { Running = false let fields = ['points', 'pointsz', 'centroids', 'centroidsz'] fields.forEach(f => console.log(f)) } Why does this happen?

Unable to change Cloud scheduler timezone for PubSub Cloud Function deploy via CICD Posted: 30 May 2021 08:10 AM PDT Suddenly the timezone for scheduler started falling back to default "America/Los_Angelos" Look at below example from firebase docs (ref: https://firebase.google.com/docs/functions/schedule-functions#write_a_scheduled_function) exports.scheduledFunctionCrontab = functions.pubsub.schedule('0 11 * * *') .timeZone('America/New_York') // Users can choose timezone - default is America/Los_Angeles .onRun((context) => { console.log('This will be run every day at 11:05 AM Eastern!'); return null; }); Unfortunately, the timeZone started failing for all new deployment via our CI pipeline and scheduled jobs started running at 11:00 AM Pacific instead of expected 11:00 AM Eastern time. Tried updating node in CI Pipeline, firebase-admin in package, but nothing helped...

Delphi - Auto incrementing a Firebird field value when using UPDATE OR INSERT INTO Posted: 30 May 2021 08:10 AM PDT I have been a Delphi programmer for 25 years, but managed to avoid SQL until now. I was a dBase expert back in the day. I am using Firebird 3.xx SuperServer as a service on a Windows server 2012 box. I run a UDP listener service written in Delphi 2007 to receive status info from a software product we publish. The FB database is fairly simple. I use the users IP address as the primary key and record reports as they come in. I am currently getting about 150,000 reports a day and they are logged in a txt file. Rather than insert every report into a table, I would like to increment an integer value in a single record with a "running total" of reports received from each IP address. It would save a LOT of data. The table has fields for IP address (Primary Key), LastSeen (timestamp), and Hits (integer). There are a few other fields but they aren't important. I use UPDATE OR INSERT INTO when the report is received. If the IP address does not exist, a new row is inserted. If it does exist, then the the record is updated. I would like it to increment the "Hits" field by +1 every time I receive a report. In other words, if "Hits" already = 1, then I want to inc(Hits) on UPDATE to 2. And so on. Basically the "Hits" field would be a running total of the number of times an IP address sends a report. Adding 3 million rows a month just so I can get a COUNT for a specific IP address does not seem efficient at all! Is there a way to do this? Thanks, Brian

I have an error with my TCP nodejs server Posted: 30 May 2021 08:09 AM PDT I wanna make an tcp server with nodejs . When i start the server in the terminal it says nothing, and when i start the client the client gets the message but in the server terminal, it prints: var net = require('net'); var client = new net.Socket(); client.connect(1337, '127.0.0.1', function() { console.log('Connected'); client.write('Hello, server!

Why does Rider add an "@" to my public variable? Posted: 30 May 2021 08:10 AM PDT I've declared a class like this: public class Cell : IEquatable<Cell> { public int id { get; } public SetOfCells group; } And each time I want to use group, Rider adds and @ before, like this: foreach (Cell cell in c1.@group) { /* blabla */ } Precision: c1.@group and c1.group both works. Why is that? (if you can tell me the right words to google to find a valuable answer I'm interested, because I couldn't find one: "csharp property +"@" doesn't help...")

Replace part of url and loop trough all the pages Posted: 30 May 2021 08:11 AM PDT I am working on a script to scrape some pages of my online supermarket. Each page has its own number The url is as follows https://www.jumbo.com/INTERSHOP/web/WFS/Jumbo-Grocery-Site/nl_NL/-/EUR/ViewOrderHistory-Paging?StatusType=Complete&PageNumber=1&PageableID=5DIKY7MVn2IAAAF5QrIGubww The part where the page number is located is Complete&PageNumber=1&PageableID where 1 is the pagenumber. I would like the to go trough al the pages up to page thirteen (I have the max pagenumver stored in a variable PageNo) I have been messing around with this part of code nested inside a replace function but I can't get the pieces together.

Auto submit form on page reload Posted: 30 May 2021 08:11 AM PDT I have tried a few different ways, but none seem to work for me. I will enter the methods I have tried after I explain a little. I have a form with the id of 'commentform', I would like to auto submit the users input when the page reloads and the user did not click the submit button. The submit button has a id of 'submit'. The textarea field of the form is 'comment' (I don't think that would be relevant. Attempt 1: Results: Auto reloads page on visit and gives error to fill in text form. <script type="text/javascript"> jQuery(window).on('load', function() { jQuery('#submit').click(); }); </script> Attempt 2: Results: Nothing happens. <script type="text/javascript"> window.onbeforeunload = function () { jQuery('#submit').click(); }); </script> Attempt 3: Results: Nothing happens. <script type="text/javascript"> window.onload = function () { jQuery('#commentform').click(); }); </script> Attempt 4: Results: Nothing happens. <script type="text/javascript"> jQuery(window).on('beforeunload', function() { jQuery('#commentform').click(); }); </script> Attempt 5: Results: Nothing happens. <body onbeforeunload ='checkRequest(event)'> //form is here <script type="text/javascript"> function checkRequest(event){ var __type= event.currentTarget.performance.navigation.type; if(__type === 1 || __type === 0){ document.getElementById('commentform').submit(); } } </script> </body> Attempt 6: Results: Nothing <script type="text/javascript"> window.onbeforeunload = refreshCode; function refreshCode(){ document.getElementById("commentform").submit(); return null; } </script> Attempt 7: Results: Nothing <script type="text/javascript"> window.onload = function(){ document.forms['commentform'].submit(); } </script>

How to show child table in Django REST Framework API view Posted: 30 May 2021 08:10 AM PDT I'm using Django as Backend, PostgresSQl as DB and HTML, CSS and Javascript as Frontend.

error UnicodeDecodeError: 'utf-8' codec can't decode byte 0xff in position 0: invalid start byte in Socket Programming Posted: 30 May 2021 08:12 AM PDT Hello so I've been doing a Python Socket Programming. What I want to do is send a string variable called "option" to server. This is the Client code option = "4" client.send(option.encode()) I got the 'error UnicodeDecodeError: 'utf-8' codec can't decode byte 0xff in position 0: invalid start byte'. So here is my server code. option = client.recv(512).decode() The option in server should received a String that has a value as "4" but like I said I got an error. Could anyone know how to solve this ? Thanks in advance.

Initializing a pydantic dataclass from json Posted: 30 May 2021 08:11 AM PDT I'm in the process of converting existing dataclasses in my project to pydantic-dataclasses, I'm using these dataclasses to represent models I need to both encode-to and parse-from json. Here's an example of my current approach that is not good enough for my use case, I have a class A that I want to both convert into a dict (to later be converted written as json) and to read from that dict. But the only way I can find to parse the json back into a model gives me back the underlying BaseModel and not the dataclass. note that I'm using the asdict function to convert the dataclass to a dict as it's what the pydantic_encoder uses to convert the dataclass to json, and using the pydantic_encoder what the documentation recommends to convert a pydantic-dataclass to json: https://pydantic-docs.helpmanual.io/usage/dataclasses/ from dataclasses import asdict from pydantic.dataclasses import dataclass from pydantic import BaseModel @dataclass class A: x: str a = A("string") a_dict = asdict(a) parsed_a = A.__pydantic_model__.parse_obj(a_dict) print(f"type of a: {type(a)}") print(f"type of parsed_a: {type(parsed_a)}") print(f"a is instance of A: {isinstance(a, A)}") print(f"parsed_a is instance of A: {isinstance(parsed_a, A)}") print(f"a is instance of BaseModel: {isinstance(a, BaseModel)}") print(f"parsed_a is instance of BaseModel: {isinstance(parsed_a, BaseModel)}") output: type of a: <class '__main__.A'> type of parsed_a: <class '__main__.A'> a is instance of A: True parsed_a is instance of A: False a is instance of BaseModel: False parsed_a is instance of BaseModel: True Is there maybe a way to initialize A from the parsed BaseModel?

How to use cakephp 2 with custom database connection and raw queries Posted: 30 May 2021 08:10 AM PDT I have to work with an Oracle database using the old database driver (ora_logon ) which is not supported by cakephp. I cant use the oci driver instead. Right now I do the follow: Every method of every model connects to the database and retrieve data class SomeClass extends Model { public function getA(){ if ($conn=ora_logon("username","password"){ //make the query // retrieve data //put data in array and return the array } } public function getB(){ if ($conn=ora_logon("username","password"){ //make the query // retrieve data //put data in array and return the array } } } I know that it is not the best way go. How could I leave cakephp manage opening and closing of the connection to the database and have models only retrieve data? I'm not interested in any database abstraction layer.

Difference between := and = operators in Go Posted: 30 May 2021 08:10 AM PDT What is the difference between the = and := operators, and what are the use cases for them? They both seem to be for an assignment?

Timezone conversion Posted: 30 May 2021 08:10 AM PDT I need to convert from one timezone to another timezone in my project. I am able to convert from my current timezone to another but not from a different timezone to another. For example I am in India, and I am able to convert from India to US using Date d=new Date(); and assigning it to a calendar object and setting the time zone. However, I cannot do this from different timezone to another timezone. For example, I am in India, but I am having trouble converting timezones from the US to the UK.

How do I enable choosing a row of a h:dataTable using JSF 2.0? Posted: 30 May 2021 08:12 AM PDT I'm starting a small project, using JSF 2.0. I'm having problems right in the start, in the CRUD of the first model implemented. What I want to do is pretty simple: The page has some filters to search, and using ajax, it populates a h:dataTable with the results. The user should now select the line with the result he wants to see/edit. But I just can't find a way to make the line selectable. This is my table: <h:dataTable var="aluno" value="#{alunoController.resultado}" > <h:column> #{aluno.id} </h:column> <h:column> #{aluno.nome} </h:column> <h:column> <!-- radiobutton, commandLink/Action goes gere --> </h:column> </h:dataTable> First I tried having a radiobutton on each line, then I learned that I can't have a radiogroup inside a table. Then I tried having a radio group inside the first cell of each line, and handling selection with a little bit of JavaScript. Somehow, the databinding doesn't work, and I cant get the selected model back in my ManagedBean. So I tried having a commandButton/Link, which sends the model via parameter.... not. It just refresh the page. The I tried using query parameters, sending the id of that row and getting the model from de database again, but I cant find a way to tell which method should be called in the ManagedBean. So I came here for my very first time, looking for suggestions. What should I do? Am I missing some information? I just don't want to believe what I want to do is too advanced.

Call Ruby class over java with jruby Posted: 30 May 2021 08:11 AM PDT If I implement a class in ruby and compile it with jrubyc than it is not possible to call it from a java class directly if I start it with java. If I see this right I have to use org.jruby.embed... to implement a wrapper which takes a class name and a method to call my ruby class. Do I have to do this also if I start the application with jruby? In my current project I start java workflow engine completely with jruby. The workflow has to call a method in a ruby class which it can't find. Maybe easier to understand: [ruby_class] <-----has to call----. | jruby [ruby_start_script] --starts--> [java wfe]
