repeat

问题 I have a bunch of similarly constructed userforms with many identical objects on them. For my labels (which number over 50), I have created a dblClick event to allow the users to change the caption. This is working fine-&-all, but I'm wondering if there's a way for me to improve my code. Is there a way to be able to avoid making dozens of copies of the same code just to handle the same event on different objects? Here is my code: Private Sub Item1_Label_dblClick(ByVal Cancel as MSForms

问题 This question already has answers here : C# creating a list of random unique integers (6 answers) Closed last year . I'm trying to fill an array with random numbers from 1-10 with no repeat. I try to do it with recursion. I'm trying to it with recursion and without (here is both with, no luck in either way). I have two codes, boths not working: 1: static int reco(int arr,int[] times) { Random rnd = new Random(); arr = rnd.Next(1, 11); return times[arr] > 0 ? reco(arr, times) : arr; } static

问题 I have a website with a repeated background image. background: url(images/back_small.png) repeat center center fixed; I would like it more, however, if the image were not repeated one copy after an other, to add some variation. The final result should be a sort of a dotted pattern where the image appears now and then, instead of being instantly repeated. I have no idea if this is possible with CSS, but if so... I'm waiting for idea :D 回答1: I recommend using a variation of the multiple

问题 I have a set of facts set/2 where the first variable is the identifier for the set and the second is the value associated with the identifier. For example: set(a,2). set(a,c). set(a,1). set(a,a). set(a,3). set(a,b). I need to construct a predicate ordering/2 (using the repeat operator) which will output the values of a specific set in their lexicographic order. For example ?- ordering(a,Output). Would result in [1,2,3,a,b,c]. What I have made thus far is this code: ordering(Input,Output):-

问题 Write a function that takes an input character and returns that character repeated 5 times using recursion. For example, if the input is 'g', then the output should be 'ggggg'. I tried the code below: function repeater(char) { let newStr = ''; if (newStr.length === 5){ return newStr; } else { newStr += char; } return repeater(char); } // To check if you've completed the challenge, uncomment these console.logs! console.log(repeater('g')); // should return 'ggggg' //console.log(repeater('j'));

问题 Is it possible to use <c:if> inside <a4j:repeat> ? I need to render a <br /> each 4 elements. I tried the following approach: <a4j:repeat value="#{MBean.sucursal.events}" var="item" rowKeyVar="idx" > <h:outputText value="#{item.eventDescription}" id="item1" /> <c: if test=#{idx % 4 == 0}> <br /> </c:if> </a4j:repeat> However, it does not render the <br /> elements at all. How can I achieve the requirement anyway? 回答1: Note: I'll ignore the careless formulation of the code which causes that it

问题 I have an R For loop that downloads data from a server and adds result to table however, I sometimes get an error stopping the loop. If I tell it to redo the last download and continue, it works for another while before the next error. The error isn't with code or data, but is random; sometimes it runs for 2.5 hours, other times it stops after 45 minutes downloading the same data . Is there a way I could get my loop to take a step back if there is an error and retry? eg. in for (i in 1:1000){
