| How to do SQL Insert in pure JSP/JSTl Posted: 23 Jan 2022 07:56 AM PST I'm trying to do a jsp page that inserts element into a SQL table that doesn't have any hardcoded naming. I've got how to get all columns name so I can access some parameters with the same name that I set in another page. But I want to control how to write that last ",": <sql:update var="tabla" dataSource="jdbc/subjetDB"> INSERT INTO <%=origen%> VALUES ( <c:forEach items="${tabla.rows[0]}" var="column"> <c:out value="${column.key},"/> </c:forEach> ) </sql:update>
This produces the following: INSERT INTO producto VALUES ( CANTIDAD_MIN, CODIGO_PRODUCTO, NOMBRE_PRODUCTO, PRECIO, )
As you can see I must control where to add , so it creates a proper SQL transaction. |
| How to get a class member of a grandparent class without using get-set? Posted: 23 Jan 2022 07:55 AM PST Can you access and change a class member of a grandparent class without using get-set and Reflect.set? I tried this code but it doesn't seem to work: class Grandparent{ this.classMember = null;//Define the class member constructor{ this.classMember = true; } } class Parent extends Grandparent{ constructor(){ super(); } } class Child extends Parent{ constructor(){ super().classMember = false; } }
Is there any way you can do this without tampering with the parent class or grandparent class, or i.e, access and set the class member(s) inside the child class? |
| DAX Rolling Average without date Posted: 23 Jan 2022 07:55 AM PST I have data in power bi containing fields for widget making devices (4), the widget serial numbers made, the dates (not time) the widgets were made and dimension A. Each device can make a widget on the same date (not necessarily everyday, other times multiple widgets per day) Trying to calculate 20 widget moving/rolling average of dimension A, filtered by device. Power BI rolling average is date based which doesn't work for this data with multiple points on same date. Tried rankx then calculating a rolling average but the resultant rolling average is incorrect:- Widgetrank = rankX( ALLSELECTED(widgettable), calculate(LASTDATE(widgettable[Date])), ,desc, Dense )
Moving Average:- DimensionA MovingAverage = var index = widgettable[widgetrank] var result = averagex( filter( widgettable, widgettable[widgetrank] < index+14 && widgettable[widgetrank] >= index ), widgettable[dimensionA] ) return fixed(result, 4)
Can anyone please advise where it is wrong or how to achieve this? |

| How to use ifelse with str_detect across multiple columns Posted: 23 Jan 2022 07:55 AM PST I have a dataframe that shows ICD-10 codes for people who have died (decedents). Each row in the data frame corresponds to a decedent, each of whom can have up to twenty conditions listed as contributing factors to his or her death. I want to create a new column that shows if a decedent had any ICD-10 code for diabetes (1 for yes, 0 for no). The codes for diabetes fall within E10-E14 i.e., codes for diabetes must start with any of the strings in the following vector, but the fourth position can take on different values: diabetes <- c("E10","E11","E12","E13","E14")
This is a small, made-up example of what the data looks like: original <- structure(list(acond1 = c("E112", "I250", "A419", "E149"), acond2 = c("I255", "B341", "F179", "F101"), acond3 = c("I258", "B348", "I10", "I10" ), acond4 = c("I500", "E669", "I694", "R092")), row.names = c(NA, -4L), class = c("tbl_df", "tbl", "data.frame"))

around the function static int __init gic_init_bases in the file /drivers/irqchip/irq-gic-v3.c. When I build it, I get this warning message (section mismatch).

This is often because gic_smp_init lacks a __init annotation or the annotation of set_smp_cross_call is wrong.

Function call chain is like this: gic_init_bases -> gic_smp_init() -> set_smp_cross_call (currently CONFIG_SMP=y). The message seems to say set_smp_cross_call is annotated with __init (meaning it is placed in .init.text), but gic_smp_init is not. Without the #pragma debug setting, there was not warning of this kind. I'm not sure if I can just add add __init to gic_smp_init() (or remove _init from set_smp_cross_call). What is the correct method to fix it? If I add __init to gic_smp_init, this warning goes away, but I think this will make the function be removed after initialization (which is ok maybe?). |

| url generated for Streamlit not working properly. ngrok tells me to register again even though I have already registered or gives me an error Posted: 23 Jan 2022 07:56 AM PST Below is my code for deploying my ml model on streamlit. I am using Google Collab !pip install streamlit --quiet !pip install pyngrok==4.1.1 from pyngrok import ngrok
%%writefile app.py import streamlit as st import joblib st.title('Spam Ham Deployment') test_model=joblib.load('spam_ham') ip=st.text_input('Enter your message') op=test_model.predict([ip]) if st.button('Predict') st.title(op)
!nohup streamlit run app.py & url=ngrok.connect(port='8501') url
Note: Initially I did not have ngrok on my PC After running the last code block I got the url but ngrok wanted me to create an account. I created an account, extracted ngrok on Windows, authenticated my ngrok agent and restarted my computer. I ran the last block again and got an error "Your account may not run more than 2 tunnels over a single ngrok client session." So I killed the process and ran all code blocks. However, after gettiing the URl and running it in the browser it tells to to register again. Note: There is a warning when the URL is generated 't=2022-01-22T22:40:55+0000 lvl=warn msg="can't bind default web address, trying alternatives" obj=web addr=127.0.0.1:4040' Why is this hapenning? Can someone tell me what I should to do in order to solve the situation? Edit: I tried to change port to 5040 that has listening state but then it shows a different error 'The connection to http://9039-35-186-177-6.ngrok.io was successfully tunneled to your ngrok client, but the client failed to establish a connection to the local address localhost:5040.' |

| How to import subset from MS Access based on condition criteria Posted: 23 Jan 2022 07:57 AM PST Hoping you can help please. EDIT 23 Jan I'm trying to use python to create a dataframe which consists of certain rows (based on condition criteria) extracted from an MS Access table. I can't seem to get the condition to work. The MS Access table has column names such as Date, Course, Horse etc. I want to, for example, get all the rows with Date = "01-Dec-2021" and Course = "Kempton". I have managed to get the following code working with one criteria: import pyodbc connStr = (r"DRIVER={Microsoft Access Driver (*.mdb, *.accdb)};" r"DBQ=C:\Users\chris\Documents\UKHR\SFF_Cum\SFFCum_py.accdb;") conn = pyodbc.connect(connStr) cursor = conn.cursor() sql = "select * FROM SFF_cumQ_O where Course = ?" cursor.execute(sql, ["Kempton"]) #print(cursor.fetchone()) print(cursor.fetchall()) cursor.close() conn.close()
However, when I try to import the rows based on Date = "01-Dec-2021" and Course = "Kempton" I get an error - "Exception has occurred: Error ('07002', '[07002] [Microsoft][ODBC Microsoft Access Driver] Too few parameters. Expected 1. (-3010) (SQLExecDirectW)')" import pyodbc connStr = (r"DRIVER={Microsoft Access Driver (*.mdb, *.accdb)};" r"DBQ=C:\Users\chris\Documents\UKHR\SFF_Cum\SFFCum_py.accdb;") conn = pyodbc.connect(connStr) cursor = conn.cursor() sql = "select * FROM SFF_cumQ_O WHERE Date = '01-Dec-2021' and Course = 'Kempton'" cursor.execute(sql) print(cursor.fetchall())

| prevent first input focus in ionic Posted: 23 Jan 2022 07:56 AM PST i have a login screen to application and when launching,the 'username' input gets the focus automatically and pops out the keyboard. when the keyboard pops out contents of my login screen pushes up resulting in wrong dimensions.

| How can I "mouse swipe" with plain Javascript? Posted: 23 Jan 2022 07:56 AM PST I'm new to Javascript and I'm trying to "master" it somehow and in order for me to do so I don't want to use any library [like jQuery] yet. That being said, I have found several ways to implement a "mouse swipe" with just Javascript like: Simulate swipe with mouse in javascript. But the answers are always very shallow in the posts that I have found. Even tho, all of the solutions point to: mousedown -> mousemove -> mouseup events. Which is what I'm doing. I set up an exercise for my self to "master" the bases of Javascript: I would have to create a flat and cross-browser-compatible interface that would allow me to save notes (in local storage) using only Javascript, css3 and html5 (the hard part is the cross browser compatibility). So I thought of a simple table with 2 columns: to save the title of the note (first column) and the note (second column). i.e. 
What matters is the table at the end. I want to be able to "mouse-swipe" the rows of the table. This is what I have come up to (I'm not going to put all the code, just the basics of what I got): First: the table is a set of classes through CSS; /*CSS*/ div.table { display: table; } div.table .row{ display: table-row; } div.table .row .col, div.table .row .col-2{ display: table-cell; }
Second: the html; <div id="savedNotesTable" class="table"> <div class="row"> <div class="col">Testing</div> <div class="col-2">This is a test</div> </div> <div class="row"> <div class="col">Testing</div> <div class="col-2">This is a test</div> </div> <div class="row"> <div class="col">Testing</div> <div class="col-2">This is a test</div> </div> </div>
Last but not least: the Javascript function addEvent(element, type, fn){ // custom add event function that cares about compatibility // returns fn } function removeEvent(element, type, fn){ /*custom remove event function that cares about compatibility and removes only the specific handler*/ } function addSwipe(element, parent){ addEvent(element, "mousedown", function(e){ var mouseupHandler = addEvent(document, "mouseup", mouseUpHandler); var mousemoveHandler = addEvent(document, "mousemove", function(e){ // element.style.position = "static"; // parent.style.left = e.pageX + 'px'; // add transition and blur to the element // mouseSwipe = absolute value of(originalPosition of mouse - e.pageX) }); function mouseUpHandler(e){ // pseudocode: // if mouseSwipe >= 50%(div size) = delete from the parent which is the "table" // transition and blur OUT to 100% and delete // if mouseSwipe < 50%(div size) = don't delete // transition back to 0% and unblur. removeEvent(document, "mousemove", mousemoveHandler); removeEvent(document, "mouseup", mouseupHandler); }; }); }; // this is just to add them to the test notes on the html // The real thing is going to add the swipe when I save the new element var table = document.getElementById("savedNotesTable"); var notes = table ? table.childNodes : undefined; for(var prop in notes){ if(prop != "length" && notes.hasOwnProperty(prop)){ if(notes[prop].nodeName != "#text"){ addSwipe(notes[prop], table); }; }; };
Am I doing it right? Or is there another way I'm not seeing? I was able to get somewhere messing with the position of the divs like position="absolute" inside the onmousedown event but that messed with the width and length of the table row. I'm looking for best practices also. |
| Getting the Redirected URL from the Original URL Posted: 23 Jan 2022 07:56 AM PST I have a table in my database which contains the URLs of some websites. I have to open those URLs and verify some links on those pages. The problem is that some URLs get redirected to other URLs. My logic is failing for such URLs. Is there some way through which I can pass my original URL string and get the redirected URL back? Example: I am trying with this URL: http://individual.troweprice.com/public/Retail/xStaticFiles/FormsAndLiterature/CollegeSavings/trp529Disclosure.pdf It gets redirected to this one: http://individual.troweprice.com/staticFiles/Retail/Shared/PDFs/trp529Disclosure.pdf I tried to use following code: HttpWebRequest req = (HttpWebRequest)WebRequest.Create(Uris); req.Proxy = proxy; req.Method = "HEAD"; req.AllowAutoRedirect = false; HttpWebResponse myResp = (HttpWebResponse)req.GetResponse(); if (myResp.StatusCode == HttpStatusCode.Redirect) { MessageBox.Show("redirected to:" + myResp.GetResponseHeader("Location")); }
When I execute the code above it gives me HttpStatusCodeOk. I am surprised why it is not considering it a redirection. If I open the link in Internet Explorer then it will redirect to another URL and open the PDF file. Can someone help me understand why it is not working properly for the example URL? By the way, I checked with Hotmail's URL (http://www.hotmail.com) and it correctly returns the redirected URL. Thanks, |
