dynamic

问题 I am having trouble adding "records" at the end of a dynamically allocated string array. Before reallocating more memory for the records to be added, everything works fine, and then I basically replicate what I initially did but now with realloc. And after I am done inputting the added Records I get an error and I don't know how to go about adding records. NOTE* The posed code is really stripped down from the original. I've tried many things but to no avail, thanks for all the help in advance

问题 I use an API call to LimeSurvey to get data into a Shiny R app I'm working on. I then manipulate the dataframe so that I have only the responses given by a certain individual over time. The dataframe can look like this: Appetite <- c("No","Yes","No","No","No","No","No","No","No") Dental.Health <- c("No","Yes","No","No","No","No","Yes","Yes","No") Dry.mouth <- c("No","Yes","Yes","Yes","Yes","No","Yes","Yes","No") Mouth.opening <- c("No","No","Yes","Yes","Yes","No","Yes","Yes","No") Pain

问题 I'm using a CMS (N2) to manage a new website. The CMS includes functionality for uploading files using the filesystem (not binary in DB, which is also possible, but I want to use filesystem). Some of the subfolders in the uploads directory need to be secured. This can be done using authorization elements in (a sub) web.config as stated here. Users and roles are managed through the admin interface and are managed by my CMS administrator. Some roles are added dynamically based on certain

问题 I'm creating a JSON out of the displayed dynamic data and sending it through AJAX to some url. Now, I'm receiving the same saved JSON earlier, through AJAX and changing my display accordingly. But for some reason I'm getting an error that 'savedData.forEach' is not a function. Am I doing anything wrong? $(document).ready(function(){ displaySavedData(); }); function displaySavedData() { $('.container').html(''); $.getJSON("/def/someData/mySaved.json", function(data) { savedData = data;

问题 This is a follow up question from UICollectionViewCell dynamic sizing for 4.4 and 5.5 inch While that solution is great, I'd like to generate a dynamic amount of item cells (kCellsPerRow) within the UIVIewController based on the device's width, aspect ratio, and amount of total items I have to display. I just can't figure out how to calculate the right amount of kCellsPerRow so that they are not too resized once they hit an aspect ratio limit. Here's what I have so far: var kCellsPerRow =

问题 I've a couple of pop-up to display the user list which would display 10 results per page, which is working fine. I'm getting the page nos. from the java servlet in the JSON. While, clicking on the next button, at times the page is refreshed multiple times. Here's the code. var currentPageNo = 0; // Keep track of currently displayed page $('.next-btn').click(function(){ // Give buttons an ID (include them in HTML as hidden) userList(currentPageNo+10); adminList(currentPageNo+10); }); $('.prev

问题 I need to display the name and split path of the path entered by a user dynamically. For that, I had split the path entered by the user and grab only certain part of it. For e.g. if the user enters path as: /content/mypath/myfolder/about/images/abc.jpg Then I am displaying images/abc.jpg. However, let's say the user only enters the name and doesn't enter the path, at least the name should be applied & displayed in that case. But it displays 0 everytime I enter a path. How do I fix this? $

问题 This program pulls two columns from the input.txt file where the first column indicates the value of the object, and the second column represents the weight. The values are imported and placed into two arrays: the value array and the weight array. The knapsack calculations are then made. There are 23 objects in total represented by the rows of the arrays. My code correctly calculates the total value that is being held in the knapsack, and will print out the correct IDs if the weight capacity
