| How can I amend this M query to make PowerBI get all the pages concurrently from a rest API? Posted: 09 May 2021 08:03 AM PDT This is my current code. It of course only returns the first page: let url = "https://id.myapi.ac.uk/connect/token", GetJson = Web.Contents(url, [ Headers = [#"Content-Type"="application/x-www-form-urlencoded;"], Content = Text.ToBinary("client_id=mechamp&client_secret=notthislol&grant_type=client_credentials&scope=myapi") ] ), FormatAsJson = Json.Document(GetJson), // Gets token from the Json response AccessToken = FormatAsJson[access_token], AccessTokenHeader = "bearer " & AccessToken, // Uses the GET search method using the bearer token from the previous POST oauth2/token method GetJsonQuery = Web.Contents("https://data.api.myapi.ac.uk/activities?recordState=0&pageSize=100", [ Headers = [#"Authorization"=AccessTokenHeader, #"api-version"="2", #"Accept"="application/json"] ] ), FormatAsJsonQuery = Json.Document(GetJsonQuery), Name"}) in FormatAsJsonQuery
I previously implemented this in Excel, using a curl request wrapped in a batch file created by VBA. Omitting the parts that already work in M query the batch file looked like this: rem ommiting getting the token and setting it as %token% set pagenum=1 set pagesize=100 curl "{https://data.api.myapi.ac.uk/activities?&page=%pagenum%&pageSize=1&recordstate=0}" -G --header "api-version: 2" --header "Authorization: Bearer %token%" --header "Accept: application/json" --trace-ascii %userprofile%\api\totalpages.txt for /F "delims=" %%a in ('findstr /I "totalCount" %userprofile%\api\totalpages.txt') do set "totalrecords=%%a" set totalrecords=%totalrecords:,"t=% set totalrecords=%totalrecords:0000: X-Pagination: {"currentPage":1,"pageSize":1otalCount":=% rem del %userprofile%\api\totalpages.txt set /a totalpages = %totalrecords%/%pagesize% set /a totalpages = %totalpages%+1 start "" /min curl "{https://data.api.heat.ac.uk/activities?&page=%pagenum%&pageSize=%pagesize%&recordstate=0&sort=-activityStartDate}" -G --data-urlencode "fields=%fields%" --header "api-version: 2" --header "Authorization: Bearer %token%" --header "Accept: application/xml" --output %userprofile%\api\file%pagenum%.txt :loop set /A pagenum=pagenum+1 start "" /min curl "{https://data.api.heat.ac.uk/activities?&page=%pagenum%&pageSize=%pagesize%&recordstate=0&sort=-activityStartDate}" -G --data-urlencode "fields=%fields%" --header "api-version: 2" --header "Authorization: Bearer %token%" --header "Accept: application/xml" --output %userprofile%\api\file%pagenum%.txt if %pagenum% LSS %totalpages% (goto :loop) rem omitting lines that copy all the destination files into one and format into into a valid single json exit
You can see it first makes a request and dumps the raw output into a file, including the headers which tell me how many records there are, which I can then use to work out how many pages there are. I googled how to get the headers in PowerBI, but in their unwisdom it seems that Microsoft have decided nobody needs them and would do bad things with them. How can I find out how many pages there are and request them all at once? Things that I couldn't make work: https://medium.com/@marktiedemann/how-to-do-pagination-in-power-query-430460c17c78 "@odata.count" was not found was the error I received, apparently not supported by this API. There was a reference to something called WebMethod.Head, which sounds interesting, but no documentation is provided on how to use it: https://msdn.microsoft.com/en-us/query-bi/m/webmethod-head I tried to recreate this exact script which claims to receive the response headers, but the syntax didn't work https://community.powerbi.com/t5/Desktop/Retrieve-API-response-headers/td-p/423704?lightbox-message-images-641107=151369i21A62C85FABC9F9C 
Apparent for some apis it's as simple as = try GetJsonQuery[next_page_url] otherwise null
And for me it's null! Odata.Feed tells me that there is no Odata at this endpoint. GetJsonQuery = OData.Feed("https://data.api.heat.ac.uk/activities?recordState=0&pageSize=100", [ #"Authorization"="bearer " & "AccessToken", #"api-version"="2", #"Accept"="application/json" ], [IncludeMetadataAnnotations="*"] ) in GetJsonQuery
Any ideas?  |
| Live update list view when data changes in database Posted: 09 May 2021 08:01 AM PDT I am creating an application with the help of GetX package. Its home screen is a list view. Data is updated via MQTT messages. when data comes from MQTT it will be updated in SQFLite. When DB changes I want to update my list view accordingly. Home page.dart class AssetListBuilder extends StatelessWidget{ final AssetController ctrl = Get.find(); @override Widget build(BuildContext context) { return GetBuilder<AssetController>( builder: (controller) { return ListView.builder( itemCount: ctrl.assetList.length, itemBuilder: (context, position) { return getCardView(ctrl.assetList[position]); }); } ); } } Controller file.dart class AssetController extends GetxController{ LoginRepository _loginRepository = LoginRepository(); AssetRepo _assetRepo = AssetRepo(); var assetList = List<Asset>(); @override void onInit() { super.onInit(); _loginRepository.connectMQTT(); fetchAssets(); } void fetchAssets() async { print('started'); var productResult = await _assetRepo.queryAllAssets(); this.assetList = productResult; update(); } }
When a MQTT message receives, it will updates the Sqlite db and calls the fetchAssets() function. It will updates the assetList also. But my UI doesn't rebuild. What's wrong with this code?  |

For example my installed version - Microsoft Edge is up to date. Version 80.0.361.111 (Official build) (64-bit) on MAC OS, but it did not display on the page that was parsed. My solution was to add my CustomEdgeDriver and add new property to wdm.edgeDriverUrl=https://msedgewebdriverstorage.blob.core.windows.net/edgewebdriver?comp=list this link displays all available versions for EDGE. I would like to ask guys from WebDriverManger, may you please fix this issue. Would be just great! Your service is cool. Thank you.  |
| Pushing new FormGroup into FormArray marks dynamic FormGroup as invalid Posted: 09 May 2021 08:02 AM PDT I'm not sure if this is a bug, almost 90% certain it's not, but I want to know the logic behind something like this occuring. I have a component, where let's say I'm initializing a FormGroup on the initialization of the component. export class FooComponent implements OnInit { form!: FormGroup; foos!: FormArray; constructor( private fb: FormBuilder ) {} ngOnInit(): void { this.form = this.fb.group({ foos: this.fb.array([]), }); } createFoo(): FormGroup { return this.fb.group({ name: ['', Validators.required], details: ['', Validators.required] }); } addFoo(): void { this.foos = this.form.get('foos') as FormArray; this.foos.push(this.createFoo()); } }
Let's say the addFoo() function gets called on a button click (which is how it is in my current application). Why is the newly pushed FormGroup marked as pristine but invalid? Even if there is a solid reason for this, shouldn't one assume that if we're dynamically generating a new FormGroup with validators, it should be considered valid upon creation or push? Is there a way around this? I don't want to have my users click a button to generate a new group of fields to fill out that are already marked invalid when they haven't done anything to those fields themselves. Is this a bug? I don't feel like my implementation is incorrect since I've followed the Angular Material documentation for this. I've tried setting the Validators.required manually after the new foo is pushed into the FormArray but this yields the same result. Any opinions and/or tips?  |
| File being corrupt when upload using multer node js Posted: 09 May 2021 08:03 AM PDT I implemented the multer upload example on restful using express. The following code is the server code. var storage = multer.diskStorage({ destination: function (req, file, cb) { cb(null, './files/') }, filename: function (req, file, cb) { crypto.pseudoRandomBytes(16, function (err, raw) { cb(null, raw.toString('hex') + Date.now() + '.xsd'); }); } }); var cpUpload = multer({ storage: storage, limits: {fileSize: 1000000}}).single('schema-file'); var app = express(); app.use(function(req, res, next) { res.header("Access-Control-Allow-Origin", "*"); res.header("Access-Control-Allow-Headers", "Origin, X-Requested-With, Content-Type, Accept"); res.header('Access-Control-Allow-Methods', 'GET,PUT,POST,DELETE,PATCH,OPTIONS'); next(); }); app.post('/ws-api-designer-upload-files', cpUpload, function (req, res, next) { console.log("filepath " + req.file.filename); cpUpload(req,res,function(err){ if(err){ res.set('Content-Type', 'application/json'); res.end(JSON.stringify({ status: 'ERROR 1', description: err.message })); return; }else{ res.set('Content-Type', 'application/json'); res.end(JSON.stringify({ status: 'SUCCESS 1', description: 'success' })); return; } }); });
But when i call this service using postman, the file are uploaded but when i compare original file between uploaded file, the uploaded file corrupted. I'm struggling on this problem for almost 1 week, please help. Note that this problem comes when code running on windows server 2008 r2. So when i run this server code on localhost there was no any problem like corrupted file. And I only upload a xsd file which is 173kb in size. This one is uploaded file (corrupt) uploaded file This one is original file original file  |
| Visual studio keyboard shortcut to go to end of line in Windows Posted: 09 May 2021 08:02 AM PDT I'm using visual studio community 2017. I want to remap the keyboard shortcut that moves the caret to the end of line (since I'm working on a laptop without the "End" key). I know how to remap visual studio keys, but I can't find the menu item for it. Do you know what is the menu/action name for it so I can change it? I can't find the answer on the web though it was asked several times.  |

| How to use the gecko executable with Selenium Posted: 09 May 2021 08:01 AM PDT I'm using Firefox 47.0 with Selenium 2.53. Recently they have been a bug between Selenium and Firefox which make code not working. One of the solution is to use the Marionnette driver. I followed the instruction of this site to use this new driver with a RemotWebDriver but I keep having the error : WARN - Exception: Exception in thread "main" org.openqa.selenium.WebDriverException: The path to the driver executable must be set by the webdriver.gecko.driver system property; for more information, see https://github.com/jgraham/wires. The latest version can be downloaded from .... The code i've tried so far is very simple : public class Test { static WebDriver driver; static Wait<WebDriver> wait; public static void main(String[] args) throws MalformedURLException { System.setProperty("webdriver.gecko.driver", "C:\\Selenium\\geckodriver.exe"); DesiredCapabilities cap = DesiredCapabilities.firefox(); cap.setCapability("marionette", true); cap.setBrowserName("firefox"); driver = new RemoteWebDriver(new URL("http://192.168.117.135:5555/wd/hub"), cap);//true to enable the JS wait = new WebDriverWait(driver, 3000); final String url = "https://www.google.com/"; JavascriptExecutor js = (JavascriptExecutor) driver; try { driver.navigate().to(url); } finally { driver.close(); } } }
I'm sure that the path to the geckodriver.exe is right and i don't see where i did the mistake. EDIT 1: I tried the following code : public class Test { static WebDriver driver; static Wait<WebDriver> wait; public static void main(String[] args) throws MalformedURLException { System.setProperty("webdriver.gecko.driver", "C:\\Selenium\\geckodriver.exe"); driver = new MarionetteDriver(); wait = new WebDriverWait(driver, 3000); final String url = "https://www.google.com/"; JavascriptExecutor js = (JavascriptExecutor) driver; try { driver.navigate().to(url); } finally { driver.close(); } } }
and it's working it seems that the problem come from the RemoteWebDriver and the gecko driver, any of you have news on it ?  |

| How to avoid embedded (inline) images when saving outlook email attachments Posted: 09 May 2021 08:02 AM PDT I have written a method to save outlook email attachments into hard disk and convert the file into Base64String. When I was saving the attachments, the embedded (inline) images also getting saved, even though they are not REAL attachments. I wanted to save only the real attachments. Then I modified the method as follows. But now I'm getting an error from the line of ".OfType()". Here is my code: private string GetBase64StringForAttachments(Outlook.MailItem mailItem) { StringBuilder builder = new StringBuilder(); Outlook.Attachments mailAttachments = mailItem.Attachments; try { if (mailAttachments != null) { Regex reg = new Regex(@"<img .+?>", RegexOptions.Singleline | RegexOptions.CultureInvariant | RegexOptions.IgnoreCase); MatchCollection matches = reg.Matches(mailItem.HTMLBody); for (int i = 1; i <= mailAttachments.Count; i++) { Outlook.Attachment currentAttachment = mailAttachments[i]; bool isMatch = matches .OfType<Match>() .Select(m => m.Value) .Where(s => s.IndexOf("cid:" + currentAttachment.FileName, StringComparison.InvariantCultureIgnoreCase) >= 0) .Any(); MessageBox.Show(currentAttachment.FileName + ": " + (isMatch ? "Inline Image" : "Attached Image")); if (currentAttachment != null) { string date = DateTime.Now.ToString("yyyymmddhhmmss"); string path = "C:\\test\\" + date + currentAttachment.FileName; //ToDo: Create Folder currentAttachment.SaveAsFile(path); FileStream fs = new FileStream(path, FileMode.Open, FileAccess.Read); byte[] filebytes = new byte[fs.Length]; fs.Read(filebytes, 0, Convert.ToInt32(fs.Length)); string encodedData = Convert.ToBase64String(filebytes, Base64FormattingOptions.InsertLineBreaks); builder.Append(encodedData).Append(","); Marshal.ReleaseComObject(currentAttachment); } } if (builder.Length > 0) { string encodedAttachments = builder.ToString().Remove(builder.ToString().Length-1); return builder.ToString(); } else return ""; } else return ""; } catch (Exception ex) { Debug.DebugMessage(2, "Error in GetBase64StringForAttachments : in AddinModule " + ex.Message); return ""; } finally { Marshal.ReleaseComObject(mailAttachments); } }
This is the Error Message: 'System.Text.RegularExpressions.MatchCollection' does not contain a definition for 'OfType' and no extension method 'OfType' accepting a first argument of type 'System.Text.RegularExpressions.MatchCollection' could be found (are you missing a using directive or an assembly reference?) What I need: I am not a big fan of LINQ. So, can you please advice me on this Is there a better way of doing this? I already tried followed the suggested answers for these questions and they did not work for me Saving only the REAL attachments of an Outlook MailItem Don't save embed image that contain into attachements (like signature image) - Is there a way to use Redemption for distinguishing the real attachments?
