| Passing Puppeteer log result into contenteditable field (non-input)? Posted: 29 Mar 2021 07:59 AM PDT It took a while to find out how to pass value into form input using this code: await page.$eval('input[name=wc_name]', (el, name) => { el.value = name; }, result.name);
But my question is, how do I pass the value into non-input (contenteditable)? I know how to do it with manual text: await page.type("[class='ql-editor ql-blank']", 'mymanualpricesethere');
I'm trying to pass result.price I have tried: await page.type("[class='ql-editor ql-blank']", (el, price) => { el.value = price; }, result.price);
But it doesn't pass (I see blank) Need some help.  |

| How to convert an iterator-like that has a `next()` methode to a regular `begin`/`end` iterator pair? Posted: 29 Mar 2021 07:59 AM PDT In the codebase I inherited, there is a class that look like an iterator (this isn't the exact code, but the logic is similar). template <class T> class IteratorLike { T* next() &; // either return a pointer to a valid value or nullptr };
The way you use it is very similar to the way you use Rust iterators: IteratorLike<...> it = ...; while(auto* item = it.next()) { do_something(*item); }
How do I convert it to make it compatible with C++ range-based for loop, algorithms, or range-v3? I'm using C++14 (gcc5.5 to be more precise), so I can't have a sentinel type that is different from the type of the iterator itself.
So far it seems that the easiest way is to store both the iterator and the next value in my wrapper: template <class T> class MyIterator { { private: IteratorLike<T> m_iter; T* m_value; public: using value_type = T; using difference_type = std::ptrdiff_t using pointer = T*; using reference = T&; using iterator_category = std::input_iterator_tag; reference operator*() const { assert(m_value && "trying to read past the end of the iterator"); return *m_value; } pointer operator->() { // I'm not sure the assert is needed here assert(m_value && "trying to read past the end of the iterator"); return m_value; } // Prefix increment Iterator& operator++() { m_value = m_iter.next(); return *this; } // Postfix increment Iterator operator++(int) { Iterator tmp = *this; ++(*this); return tmp; } // used by `my_collection.begin()` explicit MyIterator(IteratorLike<T> iter) : m_iter{m_iter} , m_value{this->self.next()} {} // missing operator == and operator != as well as the constructor // used `my_collection.end() }
However, I fail to understand what my_collection.end() should return, nor how to have meaningful comparison operators. Note: I'm basically trying to do the exact reverse of this.  |

| MSSql in a docker container on Mac: cannot connect to database Posted: 29 Mar 2021 07:59 AM PDT I've inherited a docker-ized database project - it successfully starts up a sql-server database (confirmed by the sql container's logs). I also need to be able to connect to that database, from other tools I'm running on my machine - for example DBeaver (or other db GUI). Each time I try to connect, I see this error message: The TCP/IP connection to the host host.docker.internal, port 1450 has failed. Error: "host.docker.internal. Verify the connection properties. Make sure that an instance of SQL Server is running on the host and accepting TCP/IP connections at the port. Make sure that TCP connections to the port are not blocked by a firewall.".
I get the same error when trying to connect using the IP address of docker's bridge network. I've confirmed that the sql container is forwarding it's internal port 1433 to 1450 (0.0.0.0:1450->1433/tcp). There are also no error logs in the sql docker container to help me out. I've also tried connecting using localhost & 0.0.0.0 as the host. Those throw a login failed error, which is going in the wrong direction. I am running docker for mac v20.10.5 on osx v10.15.7. I'm not sure where the problem is - docker settings? Mac settings? SQL-server configuration? Something else?  |

| async fetch & decode of .wav file works on desktop, but not on mobile (WebAudioAPI) Posted: 29 Mar 2021 07:59 AM PDT scratching my head a bit at this one. i'm currently working on a web-based synthesizer program, using WebAudioAPI. it works quite well on desktop, but on mobile it seems to fail on loading & decoding the impulse response from a wav file. the impulse response is used in conjunction with a convolver node, to implement a convolution reverb. oddly enough, everything else works fine on mobile - oscillators, waveshapers, gain nodes, etc, and the application itself does not stop running (as it would if there were an unhandled exception). it's almost as if the file itself is not being decoded or loaded into the convolver node properly - when i send my sources to the node, on mobile, it outputs only silence. here is the code i have for performing these tasks: //calculate reverb impulse response & assign to convolver node buffer calcIR(); async function calcIR() { let wavFile = await fetch("./wavData/ir4.wav"); let wavBuffer = await wavFile.arrayBuffer(); voice1.reverb.buffer = await synthCtx.decodeAudioData(wavBuffer); }
in this case, buffer is the property of the convolver node which holds the decoded impulse response data, & synthCtx is my web audio context; ir4.wav is the actual impulse response. the async function call follows the synchronous instantiation of voice1, to make sure that the nodes are actually initialized before trying to change one of their properties. i have not stopped playing around & troubleshooting, and i have a few more things i will probably try, but i figured i'd consult SE just to see if anyone here has an idea :] also, just to clarify, i have indeed tested it on mobile, and am calling the resume() function on the context from a touchEnd event, so i know the issue isn't the context being muted. as above, everything works on mobile & sounds great - save for silence from the convolver node. any help is appreciated! ramona  |

| How to fit data to a polynomial using arbitrary precision package mpmath? Posted: 29 Mar 2021 07:59 AM PDT I am using the python's arbitrary precision package mpmath. At some point, I need to fit data into a power series. I could not find in mpmath a similar function as the numpy polyfit. Then, I ended up reducing the precision to float to find the power series coefficients using numpy polyfit, as illustrated in the excerpt of the code below. for i in range(0,len(dt)): Eeq_b[i]=Es[i]*(1-nup[i])/((1+nup[i])*(1-2*nup[i])) # Young's modulus for plane strain Geq[i]=Es[i]/(2*(1+nup[i])) # shear modulus Eeq_bnp[i]=float(Eeq_b[i]) Geqnp[i]=float(Geq[i]) # power series coefficients for Eeq_b and Geq porder=12; pfitEeq_b=np.polyfit(dtnp,Eeq_bnp,porder)
As I am experiencing some convergencies issues, it seems higher precision to the coefficients of the polynomial would be required. mpmath has functions such as chebyfit, which aims at approximating a polynomial to a function (not data points) in a defined internal. Does anyone know how to fit data point to a polynomial using mpmath?  |

| Specify concrete type for methods in Scala trait Posted: 29 Mar 2021 07:59 AM PDT I want to define a method in a Scala trait where both a parameter to the method and the return type correspond to the same concrete class which extends the trait. I've tried something like the following: trait A { def foo(obj: this.type): this.type } case class B(val bar: Int) extends A { override def foo(obj: B): B = { B(obj.bar + 1) } } object Main { def main(args: Array[String]) = { val b1 = new B(0) val b2 = new B(0) val b3: B = b1.foo(b2) } }
However, trying to compile this code gives the following error: Test.scala:5: error: class B needs to be abstract. Missing implementation for: def foo(obj: B.this.type): B.this.type // inherited from trait A case class B(val bar: Int) extends A { ^ Test.scala:6: error: method foo overrides nothing. Note: the super classes of class B contain the following, non final members named foo: def foo: ((obj: _1.type): _1.type) forSome { val _1: B } override def foo(obj: B): B = { ^ 2 errors
There's obviously something I'm misunderstanding about the Scala type system here. The signature of foo in class B is what I want it to be, but I don't know how to correctly define the method in A (or if this is even possible). It seems like this question is asking something quite similar, but I don't immediately see how the answer applies in my situation.  |

Here issues is before executing the gmail.users.messages.get() function the loop is iterating. So the next token is setting. So it shows Requested entity not found error. Because the oAuth2Client is replacing  |
| Symfony - Insert in a row if a value email already exist else create a new row [duplicate] Posted: 29 Mar 2021 07:59 AM PDT Sorry for my bad english, I have 3 Entity: [My Tables][1] I have a form (demandeType) for submit a new demande, the demande form is join by "Demandeur" and "Obj" entities. DemandeType > class DemandeType extends AbstractType { > public function buildForm(FormBuilderInterface $builder, array $options): void > { > $builder > ->add('date') > ->add('obj_requested') > ->add('person_asking', DemandeurType::class) > ; > } > > public function configureOptions(OptionsResolver $resolver) > { > $resolver->setDefaults([ > 'data_class' => Demande::class, > ]); > } }
My problem is here: I need to check if a value email already exists in the database before add a new row to the demande index actually, all demande create a new line in the index, like that: [Actual Index][2] And I want to insert in date field the date of the new demande, and the Obj name on the same column if a user submit a second demande with same email adress.

| Cloud Firestore is not adding data in flutter Posted: 29 Mar 2021 07:59 AM PDT In my project, I simply created a form with an image picker. The idea is to create an event data with name, email, image and more. I already uploaded the image to Firebase storage but I cannot add the rest of my data to Firestore. The data is correctly fetched and passed to next page, though. Here is my code: onPressed: () async { if(_formKey.currentState.validate()&& _image!=null){ var name = nameController.text; var price = priceController.text; var description = descriptionController.text; var location = locationController.text; var ticket = ticketController.text; var date; if(dateChecked==true){ setState(() { date = _startDate; }); } else if(dateChecked==false){ setState(() { date=_days[_selectedDay]; }); } var time = _time; var type = _options[_selectedIndex]; var img; await Firebase.initializeApp(); Reference reference = await _storage.ref().child('${name}/${date}'); final UploadTask uploadTask = reference.putFile(_image); uploadTask.whenComplete(() async{ img = await uploadTask.snapshot.ref.getDownloadURL(); print(img); Navigator.of(context).push(MaterialPageRoute( builder: (context) => PostSuccess( name,price,date,time,location,type,_image,description,ticket ))); }); await FirebaseFirestore.instance.collection('events').doc(name).set( { 'name': name, 'price': price, 'date': date, 'time': time, 'location': location, 'type': type, 'description': description, 'tickets': ticket }); } else{ print('validate first'); } },

| How to parse complex JSON in C#? Ultimately I want to display the result in DataGridView Posted: 29 Mar 2021 08:00 AM PDT This is my first time parsing complex JSON in C# and I am little confused with parsing JSON structure like this. However, I was able to successfully parse the simple JSON. I am including the JSON and the method I am following here: [{ "L1": null, "L2": { "Name": "XXX", "contact": "xxxxx", "address": "XXXX" } }, { "L1": { "gender": "XXX", "contact": "xxxxx", "mail_address": "XXXX" }, "L2": null }]
I am using two separate class like shown below: public class L2 { public string Name{ get; set; } public string contact{ get; set; } public string address{ get; set; } } public class L1 { public string gender{ get; set; } public string contact{ get; set; } public string mail_address{ get; set; } } public class Root{ private L1 L1{get;set;} private L2 L2{get;set;} }
I am using these lines to parse: string jsonText = File.ReadAllText("log_test.txt"); List<Root> data = (List<Root>)JsonConvert.DeserializeObject<List<Root>>(jsonText);
When I run it, it runs without any errors but my ultimate goal is to display all the results in a table (or DataGridView). How do I access every properties? In the first object, L1 doesn't have any fields but it does have fields in second object. So how can I do "L1.gender" ? Any help is appreciated. Thanks !!  |

| How to disable years selection in date picker field based on value selected in another dropdown field? Posted: 29 Mar 2021 07:59 AM PDT DOB Datepicker should disable the years based on the value selected in the dropdown field. - I have a dropdown with 3 values - ADULT, INFANT and CHILD.
- There is another field called DOB which opens a datepicker.
UI image
When I select ADULT from the dropdown,in the DOB datepicker, it should enable only from last 100 years to today. It should disable the other years. (Should be able to select from 29 March 1921 to 29 March 2021(today)) Similary, when I select CHILD from the dropdown,in the DOB datepicker, it should enable only from last 12 years to today. It should disable the other years. For INFANT, last 2 years.

| the Barcode Scanner from googles mlkit doesn't recognize any barcodes Posted: 29 Mar 2021 07:59 AM PDT So i followed googles tutorial for their barcode scanner (this one) and the qr scanning works like a charm. The only problem is that i don't need qr codes but rather bar codes. But they don't work. It doesn't detect anything. I tried multiple online bar codes and ones from around the house but none got recognised as a barcode. this is the code in my activity that handles the image and scanner: public void btnClick(View v) { Intent imageTakeIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); if(imageTakeIntent.resolveActivity(getPackageManager())!=null){ startActivityForResult(imageTakeIntent, 101); } } @Override protected void onActivityResult(int requestCode, int resultCode, Intent data) { super.onActivityResult(requestCode, resultCode, data); if(requestCode==101 && resultCode==RESULT_OK) { Bundle extras = data.getExtras(); Bitmap imageBitmap = (Bitmap) extras.get("data"); imageView.setImageBitmap(imageBitmap); image = InputImage.fromBitmap(imageBitmap, 0); barCodeScanning(); } } public void barCodeScanning(){ BarcodeScannerOptions options = new BarcodeScannerOptions.Builder() .setBarcodeFormats( Barcode.FORMAT_CODE_128, Barcode.FORMAT_CODE_93, Barcode.FORMAT_CODE_93, Barcode.FORMAT_CODABAR, Barcode.FORMAT_EAN_13, Barcode.FORMAT_EAN_8, Barcode.FORMAT_ITF, Barcode.FORMAT_UPC_A, Barcode.FORMAT_UPC_E, Barcode.FORMAT_PDF417, Barcode.FORMAT_DATA_MATRIX, Barcode.FORMAT_QR_CODE, Barcode.FORMAT_AZTEC) .build(); BarcodeScanner scanner = BarcodeScanning.getClient(); Task<List<Barcode>> result = scanner.process(image) .addOnSuccessListener(new OnSuccessListener<List<Barcode>>() { @Override public void onSuccess(List<Barcode> barcodes) { System.out.println(barcodes.size()); for (Barcode barcode: barcodes) { Rect bounds = barcode.getBoundingBox(); Point[] corners = barcode.getCornerPoints(); String rawValue = barcode.getRawValue(); System.out.println(rawValue); int valueType = barcode.getValueType(); System.out.println(valueType); } } }) .addOnFailureListener(new OnFailureListener() { @Override public void onFailure(@NonNull Exception e) { e.printStackTrace(); } }); }
The console looks fine to me except the line E/libc: Access denied finding property "ro.hardware.chipname" which is marked red but didn't turn up any helpful results on google.

The line System.out.println(barcodes.size()); just prints 0 which means the barcode list is empty. Did i do something wrong or why does the qr code regognize but no bar code?  |
