| Javascript looping through a json object Posted: 31 Aug 2021 08:02 AM PDT I know this has probably been asked a million times but I spent the whole day and I cannot resolve my problem. So here it is. I have a json object in the following format const json = [[{"Id":1,"Name":"Jeffreys Bay","ProvinceID":1},{"Id":2,"Name":"Heidelberg","ProvinceID":3}]]
So I am trying to loop through this json object but just cannot be able to do. I simply can get iy working. For example: for (let x in json) { console.log(x + ': ' + json[x]); }
returns core.js:6479 ERROR SyntaxError: Unexpected token o in JSON at position 1 at JSON.parse (<anonymous>) at SafeSubscriber._next (location.page.ts:71) at SafeSubscriber.__tryOrUnsub (Subscriber.js:183) at SafeSubscriber.next (Subscriber.js:122) at Subscriber._next (Subscriber.js:72) at Subscriber.next (Subscriber.js:49) at MapSubscriber._next (map.js:35) at MapSubscriber.next (Subscriber.js:49) at FilterSubscriber._next (filter.js:33) at FilterSubscriber.next (Subscriber.js:49)

| Nested RecyclerView not working with DiffUtils Posted: 31 Aug 2021 08:02 AM PDT Hi i am kind of new to Android and i have an issue that probably will get negative qutes for this :)
i was following a Tutorial and then i decided to build an app for a Youtube Api that retrieves playlists and videos inside the playlist. The structure as follow:
-i use tabLayout with fragments "Main Fragment: generates the viewpager" and displays one tab for playlist and one for all videos of the channel
-i have only one navigation graph for all my 6 Fragments (also worth to mention i use safeArgs to pass data between fragments through transition) -i have a ButtomNavigation also
anyway the main concern here i have 2 Adapters one for playlists(which i use inside the PlaylistFragment (consider as parent Fragment) to setup the recyclerView) and one for the items inside the playlist(which used for the PlaylistitemsFragment(child))
so normaly parent fragment displays the playlist and when navigated with itemclick it goes to corresponding videos inside this playlist
Main issue i've decided to nest the PlaylistItems inside the playlist horizontally so it would be the playlist vertically and their relatives items horizontally.
i did create a new Recycler View inside the main_item for the parent RecyclerView
inside my first adapter i did exactly the same everywhere i searched its kind of the same concept, but for some reasons when call the second adapter(playlistitems) it doesn't get to onCreateViewHolder or onBindViewHolder and eventually doesn't inflate the child RecyclerView and when i debugged i found the getItemCount doesn't return anything
override fun getItemCount(): Int { return differ.currentList.size }
I just dont understandt why the child recyclerview is generated but no inflated and why differ.currentList.size returns zero

| VBA to loop through range then run code updating worksheet reference Posted: 31 Aug 2021 08:01 AM PDT sorry I am a newbie looking for help. I am having a complete mind block so reaching out for some help. I have a document that contains a couple of macros; 1st extracts data from a data sheet (datasheet) and copies to a specific worksheet (reportsheet) when the criteria is met. The 2nd macro will save this as a PDF, create an email and send to the person. I have 100+ sheets and would require to duplicate these macros 100 times. I want to combine these into 1 macro, however, i would like to loop through a range ("B6:B123") and if in that range the cell <> 0 then the macro need to run but the reportsheet reference i'd like to update dynamically using the adjacent cell value (Dx) that would trigger these to run. Macro 1 Sub Search_extract_135() Dim datasheet As Worksheet Dim reportsheet As Worksheet Dim ocname As String Dim finalrow As Integer Dim i As Integer Set datasheet = Sheet121 ' stays constant Set reportsheet = Sheet135 'need to update based on range that <>0 then taking cell reference as ocname = reportsheet.Range("A1").Value 'stays constant reportsheet.Range("A1:U499").EntireRow.Hidden = False reportsheet.Range("A5:U499").ClearContents datasheet.Select finalrow = Cells(Rows.Count, 1).End(xlUp).Row For i = 2 To finalrow If Cells(i, 1) = ocname Then Range(Cells(i, 1), Cells(i, 21)).Copy reportsheet.Select Range("A500").End(xlUp).Offset(1, 0).PasteSpecial xlPasteAll datasheet.Select End If Next i reportsheet.Select Range("A4").Select Call HideRows
End Sub Macro 2 Sub Send_Email_135() Dim wPath As String, wFile As String, wMonth As String, strPath As String, wSheet As Worksheet Set wSheet = Sheet135 wMonth = Sheets("Journal").Range("K2") wPath = ThisWorkbook.Path ThisWorkbook.Path wFile = wSheet.Range("A1") & ".pdf" wSheet.Range("A1:U500").ExportAsFixedFormat Type:=xlTypePDF, Filename:=wPath & "-" & wFile, _ Quality:=xlQualityStandard, IncludeDocProperties:=True, _ IgnorePrintAreas:=False, OpenAfterPublish:=False strPath = wPath & "-" & wFile Set dam = CreateObject("Outlook.Application").CreateItem(0) ' dam.To = wSheet.Range("A2") dam.cc = wSheet.Range("A3") dam.Subject = "Statement " & wMonth dam.Body = "Hi" & vbNewLine & vbNewLine & "Please find attached your statement." & Chr(13) & Chr(13) & "Regards," & Chr(13) & "xxxxx" dam.Attachments.Add strPath dam.Send MsgBox "Email sent" End Sub
I am hoping this makes sense. will try to summarise below; The format of the excel document has names in column A, numeric values in column B and SheetCode in column D. When cell within Range("B6:B123") <> 0 then run the 2 macros above but need reportsheet from macro 1 & wSheet from macro 2 to use the same value in column D to references the specific worksheet code for the person that doesn't equal 0. If this isn't going to work i will create multiple macros. Thank you in advance.  |

| React-Redux increment / decrement issue Posted: 31 Aug 2021 08:01 AM PDT I'm doing some React-Redux practice and I've noticed a behaviour I can't understand: it works or not depending if i use + 1 / - 1 or ++ / -- operators. This is my reducer: const counterReducer = (state = { counter: 0 }, action) => { switch (action.type) { case "INCREMENT": return { counter: state.counter + 1, }; case "DECREMENT": return { counter: state.counter - 1, }; default: return state; } };
and it works fine. but if i change the incement and decrement to: const counterReducer = (state = { counter: 0 }, action) => { switch (action.type) { case "INCREMENT": return { counter: state.counter++, }; case "DECREMENT": return { counter: state.counter--, }; default: return state; } };
It will still fire the acrion without updating the Redux state.  |

| Deploying when NPM package is outdated Posted: 31 Aug 2021 08:01 AM PDT I want to deploy an Angular 12 app that uses d3-org-chart, which in turn imports d3-flextree. When I start my project using ng build it generates the following error: ./node_modules/d3-flextree/src/flextree.js:247:19-26 - Error: Should not import the named export 'version' (imported as 'version') from default-exporting module (only default export is available soon)
I can see that the error was fixed in the project GitHub repository in this commit, and I made the same change locally and it works fine. Another developer has raised an issue on the project page to get the NPM package updated. My issue is that the code was fixed in github, but not updated on NPM. So when I use npm install, or when I deploy my app in a docker container which then runs ng build it pulls down the outdated NPM version and the error occurs, preventing startup. Obviously, this will be fixed when the maintainer updates the NPM package, but until this happens what is the least ugly solution to enable me to deploy my docker container without the error?  |

| How to convert WAVE file with 3 channels to MP3 file (using LameMP3FileWriter)? Posted: 31 Aug 2021 08:02 AM PDT I'm currently working on an application which records audio from devices. One device gives us a IWaveIn with 1 channel and the other of 2 channels, resulting in a WAVE file of 3 channels using new MultiplexingWaveProvider(waveIns.Select(waveIn => new WaveInProvider(waveIn))); But when I try to convert it using LameMP3FileWriter, it complains about only supporting up to 2 channels: System.ArgumentException: Unsupported number of channels 3 Parameternaam: format bij NAudio.Lame.LameMP3FileWriter..ctor(Stream outStream, WaveFormat format, LameConfig config) bij NAudio.Lame.LameMP3FileWriter..ctor(Stream outStream, WaveFormat format, LAMEPreset quality, ID3TagData id3)

| How to copy 2D array Using loops, copy all of the scores for exam 1 and 2 into the new 2D array. (Do not include the -1 values) Posted: 31 Aug 2021 08:02 AM PDT import java.util.Arrays; public class Review { public static void main(String[] args) { //First, declare and initialize a 4x3 2D array of doubles called `scores` which will contain the exam data for four students. The rows will represent the student and the columns will represent the exam number. You already know the first exam scores (80.4, 96.2, 100.0, 78.9). Use initializer lists to store the first exam scores in the first column and -1 for the remaining exams. Use the provided print statement to print the result in the console. double[][] scores = {{80.4, -1, -1}, {96.2, -1, -1}, {100.0, -1, -1}, {78.9, -1, -1}}; System.out.println(Arrays.deepToString(scores)); //The next set of exams have occurred. Using 4 lines of code, manually enter the scores (89.7, 90.5, 93.6, 88.1) for the second exam (column 1). Use the provided print statement to print the updated 2D array as well. scores[0][1] = 89.7; scores[1][1] = 90.5; scores[2][1] = 93.6; scores[3][1] = 88.1; System.out.println(Arrays.deepToString(scores)); //You have realized that you will only be keeping track of 2 exam grades instead of 3. Declare and initialize an empty 4x2 2D array of double values called newScores double[][] newScores = new double[4][2]; //Using loops, copy all of the scores for exam 1 and 2 into the new 2D array. (do not include the -1 values) for(int i = 0; i < scores[0].length; i++) { for(int j = 0; j < scores.length; j++) { newScores[i][0] = scores[i][1]; } } System.out.println(Arrays.deepToString(newScores)); //You have allowed the students to complete an extra credit activity to contribute towards their scores. For all exam grades less than 90, add 2 additional points to the grade in `newScores` System.out.println(Arrays.deepToString(newScores)); } }
Here's the question I have and what I have tried. Using loops, copy all of the scores for exam 1 and 2 into the new 2D array. (Do not include the -1 values) //Using loops, copy all of the scores for exam 1 and 2 into the new 2D array. (do not include the -1 values) for(int i = 0; i < scores[0].length; i++) { for(int j = 0; j < scores.length; j++) { newScores[i][0] = scores[i][1]; } } System.out.println(Arrays.deepToString(newScores));
Here's the hint. Remember to copy values over using: twoDArrayOne[i][j] = twoDArrayTwo[i][j]; when in a nested loop. Here's the output am getting from the console. [[80.4, -1.0, -1.0], [96.2, -1.0, -1.0], [100.0, -1.0, -1.0], [78.9, -1.0, -1.0]] [[80.4, 89.7, -1.0], [96.2, 90.5, -1.0], [100.0, 93.6, -1.0], [78.9, 88.1, -1.0]] [[89.7, 0.0], [90.5, 0.0], [93.6, 0.0], [0.0, 0.0]] [[89.7, 0.0], [90.5, 0.0], [93.6, 0.0], [0.0, 0.0]]

Posted: 31 Aug 2021 08:02 AM PDT $ cat test.sh #! /bin/bash if [ -f /home/amnesia/Persistent/yubikey-manager-qt.AppImage ]; then ykman="/home/amnesia/Persistent/yubikey-manager-qt.AppImage ykman" elif [ -f /Applications/YubiKey\ Manager.app/Contents/MacOS/ykman ]; then ykman="/Applications/YubiKey\ Manager.app/Contents/MacOS/ykman" else printf "$bold$red%s$normal\n" "Could not find YubiKey Manager binary" exit 1 fi $ykman list $ test.sh ./test.sh: line 12: /Applications/YubiKey\: No such file or directory
./test.sh: line 12: /Applications/YubiKey: No such file or directory How can I fix above error? Using following approach solves issue on macOS but breaks things on Tails because of ykman AppImage requirement. $ cat test.sh #! /bin/bash if [ -f /home/amnesia/Persistent/yubikey-manager-qt.AppImage ]; then ykman="/home/amnesia/Persistent/yubikey-manager-qt.AppImage ykman" elif [ -f /Applications/YubiKey\ Manager.app/Contents/MacOS/ykman ]; then ykman="/Applications/YubiKey Manager.app/Contents/MacOS/ykman" else printf "$bold$red%s$normal\n" "Could not find YubiKey Manager binary" exit 1 fi "$ykman" list
Thanks for helping out!  |
| Material.io Tabs: where to put the tab content? Posted: 31 Aug 2021 08:01 AM PDT I'm trying to use material.io tabs in a project, anyway the html structure is not well documented: https://material.io/components/tabs/web#design-api-documentation <div class="mdc-tab-bar" role="tablist"> <div class="mdc-tab-scroller"> <div class="mdc-tab-scroller__scroll-area"> <div class="mdc-tab-scroller__scroll-content"> <button class="mdc-tab mdc-tab--active" role="tab" aria-selected="true" tabindex="0"> <span class="mdc-tab__content"> <span class="mdc-tab__icon material-icons" aria-hidden="true">favorite</span> <span class="mdc-tab__text-label">Favorites</span> </span> <span class="mdc-tab-indicator mdc-tab-indicator--active"> <span class="mdc-tab-indicator__content mdc-tab-indicator__content--underline"></span> </span> <span class="mdc-tab__ripple"></span> </button> </div> </div> </div> </div>
where am i supposed to put the tab body content? It seems they shows only how to build a tab bar but not the whole functionality?  |
| Adjusting height of mat-form-field Angular Material Posted: 31 Aug 2021 08:01 AM PDT I am running into an issue with a simple adjust of a mat-form-field that holds my autocomplete input. From the image you can see if it's outside the mat-toolbar height, but I have not found a simple way to adjust the height of the entire input so it can stay inside the toolbar area. Width works fine. Height does not. input outside toolbar 
My html code is as follows: <mat-toolbar > <span style="width:200px">Test</span> <label>{{prodPointId}}</label> <form class="example-form" > <mat-form-field appearance="outline" margin=" 10px" class="example-full-width searchField" > <mat-label>Search...</mat-label> <input type="text" matInput [formControl]="myControl" [matAutocomplete]="auto" [(ngModel)]="value" > <button mat-button *ngIf="value" matSuffix mat-icon-button aria-label="Clear" (click)="value=''"> <mat-icon>close</mat-icon> </button> <mat-autocomplete #auto="matAutocomplete" [displayWith]="displayFn"> <mat-option *ngFor="let option of filteredOptions | async" [value]="option.prodPointName" (click)="pointSelected(option.prodPointId)" [routerLink]="['/coredata', option.prodPointId]" > <mat-icon>home</mat-icon> {{option.prodPointCode}} : {{option.prodPointName}} </mat-option> </mat-autocomplete> </mat-form-field> </form> </mat-toolbar>
When I pull up chrome dev tools I attempted to adjust the height in the CSS for the component using div.mat-form-field and several other options, but nothing has seemed to work. Looking at the documentation at Angular Material, I haven't found anything that shows me how to control this simple styling adjustment. What am I missing. Is it so simple and I just overthinking it? Thanks!  |
| Junit 5 - No ParameterResolver registered for parameter Posted: 31 Aug 2021 08:02 AM PDT Source : JUnit 5, Eclipse 4.8 , Selenium I can write up and execute Selenium script without any special test framework but I wanted to use Junit 5 (because we have dependency with other tools) and I have never seen such error "org.junit.jupiter.api.extension.ParameterResolutionException" while working with Junit 4. Currently it's Junit 5 and I googled it to get some sort of idea but can not resolve the issue.

| Selenium adding items from a Web element list to a string array list Posted: 31 Aug 2021 08:01 AM PDT I'm doing some automated testing and I'm trying to save some items from a web element list to a string array, there should be some parsing involved but I'm not sure how, see code snippet below public void I_should_see_the_following_folders(DataTable expectedData) throws Throwable { int tbl1; int tbl2; List<List<String>> featureTable = expectedData.raw(); WebElement folders = driver.findElement(By.id("folders")); List <WebElement> emailFolders = folders.findElements(By.className("folder-name")); List<String> foo = new ArrayList<String>(); for (List<String> featuresList : expectedData.raw()) foo.add(featuresList.get(0)); tbl1 = emailFolders.size(); tbl2 = featureTable.size(); List<String> webList = new ArrayList<String>(); for(int i=0;i<tbl1;i++){ webList.add(emailFolders.get(0)); } }
what I'm trying to do is take a datatable list of items, convert it into a string array and then take a list of items from the webpage and also store it into a string array and then compare each array to determine if the elements are present and are the same in not particular order. I think I got the data table array list to work, but need some help with the web elements array list. Thanks!!!  |
| Can not identify the object in QTP Posted: 31 Aug 2021 08:01 AM PDT I'm using QTP 9.2. While running script i got this error repeatedly Cannot identify the object "Login1$Password" (of class WebEdit). Verify that this object's properties match an object currently displayed in your application. When i run the script for first time it runs perfectly but now this error occurred. I have tried all the possible solution check object properties through object repository and object spy and enable smart identification result shows: object not unique (3 objects found) or object not found..  |
