dynamic

问题 First I should perhaps explain what I want to do... I have 'n' amounts of files with 'n' amount of lines. All I know is that the line count will be even. The user selects the files that they want. This is saved into an array called ${selected_sets[@]} . The program will print to screen a randomly selected 'odd numbered' line from a randomly selected file. Once the line has been printed, I don't want it printed again... Most of it is fine, but I am having trouble creating arrays based on the

问题 Each time i make small changes, i need to submit the app for approval and need to wait to review process to complete, so till what extent i can exploit dynamic code insertion or at least can i change the view of a view controller using the nib file which i will be downloading to document directory dynamically? 回答1: For the most part, the answer is no, and intentionally so. In particular, you cannot run executable code that you download. If you figured out a workaround to allow it technically

问题 I've a bootstrap modal which contains a table of users. I can select a user from the table and on clicking 'save', the details of seleced user is displayed. I'm displaying 10 users per page in the table of the modal. However, if I select any user from page 1 and then click next to select some users from page 2 and click on 'save', my selection from page 1 is not retained. I mean the checkbox is cleared on page 1, whenever I click on next or previous. How do I retain this selection on my

问题 I have a web application where i want my users to dynamically create a type...i can do this using reflection but i am not sure of how to persist that type using Entity framework 回答1: Once again - whether this approach is applicable or not (and in any case it is a workaround), depends on your scenario. However, what you can do is serialize your object and store it in a database field. You can basically serialize into any format (binary, json, xml, ...). Note: when using the xml datatype you

问题 I'm trying to implement a function that can increase the size of a dynamic array of any data type by one, having the array keep all of it's existing data. I want to do this since we regularly need to use and resize dynamic arrays for practical projects in class, so as much as I would like to, I can't use vectors. I would firstly like to know if this can be done, and if so, if someone could show me how. This is what I have so far. template <typename Temp> void incArraySize(Temp * dynamicArray,

问题 I have 2 Button which when clicked either add a new paragraph or remove a current paragraph. This is done using jQuery . I am also using jQuery to change the color of the paragraph text from black to red on hover . The problem that I am having is that after I add a new paragraph with jQuery , the hover effect is not being applied to it. It works for the original paragraphs but not for the ones that are being created dynamically. When I look at the source code of the page I see that the

问题 It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, visit the help center. Closed 7 years ago . I want to create certain number of threads in my program where the number of threads to be created is provided by the user at run-time. Any suggestions ?? 回答1: There are a number of ways to do this. A for loop is

问题 I am trying to run a JMeter script but it is failing at login. The reason is, password is getting encrypted using RSA algorithm and that is using javascript. so the password that is saved at the time of recording wont work and I am not able to get the dynamic value of encrypted password as it is being encrypted using javascript which is not supported by JMeter. because of javascript usage at runtime, I can not use regular expression to look in response data as this is not part of response. I

问题 I programmatically create a Form with two textboxes . My goal is to disable one textbox if I type something in the second one and contrariwise. I managed to disable second textbox on first textbox textchange,but can't figure out how enable it when the first textbox .Text is empty. Here is the code : private void metaName_TextChanged(object sender,EventArgs e) { var ctrl = (Control)sender; var frm = ctrl.FindForm(); TextBox metaTxt = null; foreach (var ctr in frm.Controls) { if (ctr is TextBox

问题 I am currently taking a Java Programming class and we are on the topic of dynamic arrays. We were asked to write a program using dynamic arrays that would print out the Fibonacci Sequence. This is what I have: public class Fibonacci { private static int[] data; public static void DynamicArray() { data = new int[1]; } public static int get(int position) { if (position >= data.length){ return 0; } else { return data[position]; } } public static void put(int position, int value) { if(position >=
