key-value

问题 I'm using ms botbuilder v 4 I'm using webcontrol, webchat.js, latest, react Case is pretty trivial: I want to show list of possible values in dropdown, values will be dynamic (comes from API, i need Titles and Values (Ids) there. Then when user selects some item and clicks OK i want to get value (Id) and work further with that. As i got it for now only way to show dropdown is using adaptive cards, in v3 there was an option to use adaptive cards in prompts and it also planned for next version:

问题 I have a key-value pairs table. I have created a script using dynamic sql that pivots the table correctly. However, the keys have different data types. Is there a way to cast the keys during or after the pivot dynamically? I can have the data types in the same key-value pairs table for each key or in a separate table linkable by the key. Dynamic sql is used because I wont always know the columns. There will always be a data type. An example of the starting table: sampleid key value datatype -

问题 I have a problem were i need to aggregate some vectors in order to find some statistics. For example i have vectors of doubles and i need to sum them. My vectors look like this: 1,0,3,4,5 2,3,4,5,6 3,4,5,5,6 My key-value pairs so far are (String,String). But every time i need to add these vectors, i first have to convert them to double arrays, add them up and finally convert the aggregate vector into string. I think it would be a lot faster if i just could have key-value pairs in the form

问题 Is it possible to include hyperlink as a part of text in app.config key value pair (email body text as value)? I want to generate email body from app.config key value. For example: <add key="EmailBody" value="Email body goes here with <a href="some link">click here</a> hyperlink/> I know this is not valid, but is there a way to achieve this? Thanks in advance! 回答1: The way i would do it is write your email body as shown but do not actually add the etc. Instead, do something like the following

问题 I have just learned about key/value pairs. I tried looking for an existing answer and tried to understand what I could about key/value pairs and associative arrays. Though this is becoming a little too time-consuming. I am having troubles figuring out how to iterate through this multi-dimensional associative array without getting any errors. $arr = array( 'test1' => array( 'testing 1-1' => array('testing 1-1-1', 'testing 1-1-2', 'testing 1-1-3'), 'testing 1-2' => array('testing 1-2-1',

问题 I need to transform my Java-pair-rdd to a csv : so i m thinking to transform it to rdd, to solve my problem. what i want is to have my rdd transformed from : Key Value Jack [a,b,c] to : Key value Jack a Jack b Jack c i see that it is possible in that issue and in this issue(PySpark: Convert a pair RDD back to a regular RDD) so i am asking how to do that in java? Update of question The Type of my JavaPairRdd is of Type : JavaPairRDD<Tuple2<String,String>, Iterable<Tuple1<String>>> and this is

问题 i am new to java and was learning the concepts of hashmaps. I am confused how the keys are sorted in hashmaps. i understood that its based on string length. but i am confused how data is sorted when the string length is same. import java.util.HashMap; import java.util.Iterator; import java.util.Map; import java.util.Set; public class HashMapExample { public static void main(String args[]) { Map<String,String> map = new HashMap<String,String>(20);//SPECIFYING THE TYPE FOR FINDING HASH CODES. /

问题 I'm trying to update my gems using a Gemfile but always fails in the same line: Gemfile: group :doc do gem 'sdoc', require: false end Command: $ bundle update I'm always getting this error: Gemfile syntax error: /Users/GrzegorzFeathers/Documents/Edx/SaaS/rottenpotatoes/Gemfile:32: syntax error, unexpected ':', expecting kEND gem 'sdoc', require: false When I change that line syntax to this, the problem was solved: gem 'sdoc', :require => false But why can't I use the other one?, I checked my

问题 in this simple program that prompts users to input a polynomial, I used int 999 as a value that represents end of input. However, this is not a good design because users will not be able to input a polynomial node with a coeff of 999. Is there an alternative key that can be unique to represent end of input? Relevant Code : int coeff; int expon; int i = 1; printf("\nInput for polyNode %d (999 for exit):",i); printf("\n\tInput coeff : "); scanf("%d",&coeff); while(coeff != 999) { printf("

问题 I search for a datastructure, where I can store several key-value pairs. The data essentially looks like this: (1 , value_1) (2 , value_2) So I thought of using HashMap. Sadly this won't work for me, because multiple values to one key can occur. (In the example above: (1 , value_2) might be another entry ) Is there any way of performantly storing this data, except creating a List with a new Object or something like this. get(1) should return value_1 and value_2 as a list or set or anything
