  • How to insert an integer into a database through command prompt

    - by jpavlov
    I am trying to insert a integer into a database in C# using the code below, but everytime I run the compiler informs me that my integer is not a valid column "Invalid Column Name UserID" Does anyone have any insight on this? Thanks. Console.WriteLine("Please enter a new User Id"); string line = Console.ReadLine(); int UserID; if (int.TryParse(line, out UserID)) { Console.WriteLine(UserID); Console.ReadLine(); } //Prepare the command string string insertString = @"INSERT INTO tb_User(ID,f_Name, l_Name) VALUES (UserID,'Ted','Turner')";

  • Python Importing object that originates in one module from a different module into a third module

    - by adewinter
    I was reading the sourcode for a python project and came across the following line: from couchexport.export import Format (source: https://github.com/wbnigeria/couchexport/blob/master/couchexport/views.py#L1 ) I went over to couchexport/export.py to see what Format was (Class? Dict? something else?). Unfortunately Format isn't in that file. export.py does however import a Format from couchexport.models where there is a Format class (source: https://github.com/wbnigeria/couchexport/blob/master/couchexport/models.py#L11). When I open up the original file in my IDE and have it look up the declaration, in line I mentioned at the start of this question, it leads directly to models.py. What's going on? How can an import from one file (export.py) actually be an import from another file (models.py) without being explicitly stated?

When i tested by keeping alert in both Jquery check is executing first and calling the CheckThis function where as window.load is taking some time and executing after it. Please suggest

  • Given two lines on a plane, how to find integer points closest to their intersection?

    - by Lukasz Lew
    I can't solve it: You are given 8 integers: A, B, C representing a line on a plane with equation A*x + B*y = C a, b, c representing another line x, y representing a point on a plane The two lines are not parallel therefore divide plane into 4 pieces. Point (x, y) lies inside of one these pieces. Problem: Write a fast algorithm that will find a point with integer coordinates in the same piece as (x,y) that is closest to the cross point of the two given lines. Note: This is not a homework, this is old Euler-type task that I have absolutely no idea how to approach. Update: You can assume that the 8 numbers on input are 32-bit signed integers. But you cannot assume that the solution will be 32 bit.

  • Selecting an element based on class and id in jquery - similar to an SQL query

    - by Ankur
    I want to select an element based on it's class and id, I have seen many similar questions on SO. Most of the users ask why would you ever want to do this - which is not very helpful, trust me, this is the simplest way of solving my UI problem, and it's a very unique and intereting UI related to making generic triple stores easily browsable. At the moment the jQUery looks like this: $(document).ready( function() { $(".predicates").hide(); $(".objects").hide(); $("#subject").click( function() { $("#predId, .predicates").toggle(); // this line } ); $("#predId").click( function() { $("#objId, .objects").toggle(); } ); }); The line I am really interested in is this $("#predId, .predicates").toggle(); how do I get the select to ensure that both #predId and .predicates are true, at the moment it seems that only one or the other has to be true. Is there something like an && operator?

  • Track/Display Array Index As Part Of Cout (C++)

    - by John Smith
    Hi, I have a command line C++ program that lets you enter basic information about a person (ID number, name, age, etc.) and I want to output to a console in the following manner: ------------------------------------------------------------------- Index ID # First Name Last Name Age ------------------------------------------------------------------- 0 1234 John Smith 25 The person objects are stored in an array of Persons and I've overload the ostream (<<) operator to print out all of the fields like you see. The dashed lines and header come from a displayHdg() function. Anyhow, I have not been able to figure out how to get the proper index value for the array. Ideally, I'd like to generate the indices for each line, but all my attempts have failed. The array is looped through and each object printed in the main() function, and the ostream is overloaded in a person class, so I tried to use global variables as well as static variables, and all of those produce incorrect numbering (i.e. show 0, 1 the first time (for 2 objects), then change to 1, 2 on the next display). Any ideas?

  • Google Maps and Json structure

  • In Javascript, how to avoid NaN when adding arrays

    - by Jonas
    I'm trying to add the values of two arrays in javascript eg. [1,2,1] + [3,2,3,4] The answer should be 4,4,4,4 but I'm either getting 4,4,4 or 4,4,4,NaN if I change the 1st array length to 4. I know a 4th number needs to be in the 1st array, but i can't figure out how to tell javascript to make it 0 rather then undefined if there is no number.

  • Why is my program freezing when I use a method? (Java)

    - by user2915567
    When I use a boolean method in the Main body, my program freezes and stops working. I've tried putting the method at different places but the exact same thing happens - it freezes. The method is really simple and well-written, I'm not sure what's causing the problem. P.S. The method is on the bottom of the code. Thanks for your help! Edit: That was a dumb question now that I look at it. Thanks again everyone! public static void main(String[] args) { Scanner keyboard = new Scanner(System.in); int stringNumber = 0; String[] stringArray = new String[10]; for (int i = 0; i <= stringArray.length; i++) { boolean itemExists = false; boolean AddItem = AddItem(); if (AddItem == true) { out.println("\nEnter a string"); String input = keyboard.next(); if (i > 0) { for (int j = 0; j < stringArray.length; j++) { if (input.equalsIgnoreCase(stringArray[j])) { itemExists = true; out.println("Item \"" + input + "\" already exists."); break; } } } if (itemExists == false) { stringArray[stringNumber] = input; out.println("\"" + stringArray[stringNumber] + "\"" + " has been stored.\n"); } else { out.println("Try again."); i--; } PrintArray(stringArray); stringNumber++; } } } // This is the method I was talking about // public static boolean AddItem() { Scanner keyboard = new Scanner(System.in); int input = keyboard.nextInt(); out.println("If you want to add an item, Press 1"); if (input == 1) { return true; } else { out.println("Invalid input."); return false; } }

  • How can I refactor this JavaScript code to avoid making functions in a loop?

    - by Bungle
    I wrote the following code for a project that I'm working on: var clicky_tracking = [ ['related-searches', 'Related Searches'], ['related-stories', 'Related Stories'], ['more-videos', 'More Videos'], ['web-headlines', 'Publication'] ]; for (var x = 0, length_x = clicky_tracking.length; x < length_x; x++) { links = document.getElementById(clicky_tracking[x][0]) .getElementsByTagName('a'); for (var y = 0, length_y = links.length; y < length_y; y++) { links[y].onclick = (function(name, url) { return function() { clicky.log(url, name, 'outbound'); }; }(clicky_tracking[x][1], links[y].href)); } } What I'm trying to do is: define a two-dimensional array, with each instance the inner arrays containing two elements: an id attribute value (e.g., "related-searches") and a corresponding description (e.g., "Related Searches"); for each of the inner arrays, find the element in the document with the corresponding id attribute, and then gather a collection of all <a> elements (hyperlinks) within it; loop through that collection and attach an onclick handler to each hyperlink, which should call clicky.log, passing in as parameters the description that corresponds to the id (e.g., "Related Searches" for the id "related-searches") and the value of the href attribute for the <a> element that was clicked. Hopefully that wasn't thoroughly confusing! The code may be more self-explanatory than that. I believe that what I've implemented here is a closure, but JSLint complains: http://img.skitch.com/20100526-k1trfr6tpj64iamm8r4jf5rbru.png So, my questions are: How can I refactor this code to make JSLint agreeable? Or, better yet, is there a best-practices way to do this that I'm missing, regardless of what JSLint thinks? Should I rely on event delegation instead? That is, attaching onclick event handlers to the document elements with the id attributes in my arrays, and then looking at event.target? I've done that once before and understand the theory, but I'm very hazy on the details, and would appreciate some guidance on what that would look like - assuming this is a viable approach. Thanks very much for any help!

  • UIButton custom font vertical alignment

    - by Willshaw Media
    I've got a UIButton which uses a custom font, which is set when my view loads: - (void)viewDidLoad { [super viewDidLoad]; self.searchButton.titleLabel.font = [UIFont fontWithName: @"FONTNAME" size: 15.0 ]; } The problem I've got is that the font is appearing to float up of the center line. If I comment out this line, the default font appears vertically centered fine. But changing to the custom font breaks the vertical alignment. I'm getting the same issue on a Table Cell with a custom font too. Do I need to tell the view somewhere that the custom font is not as tall as other fonts? EDIT: I've just realized that the font I'm using is a Windows TrueType Font. I can use it fine in TextEdit on the Mac, only a problem with the alignment in my App

  • Can't get InputStream read to block...

    - by mark dufresne
    I would like the input stream read to block instead of reading end of stream (-1). Is there a way to configure the stream to do this? Here's my Servlet code: PrintWriter out = response.getWriter(); BufferedReader in = request.getReader(); try { String line; int loop = 0; while (loop < 20) { line = in.readLine(); lgr.log(Level.INFO, line); out.println("<" + loop + "html>"); Thread.sleep(1000); loop++; // } } catch (InterruptedException ex) { lgr.log(Level.SEVERE, null, ex); } finally { out.close(); } Here's my Midlet code: private HttpConnection conn; InputStream is; OutputStream os; private boolean exit = false; public void run() { String url = "http://localhost:8080/WebApplication2/NewServlet"; try { conn = (HttpConnection) Connector.open(url); is = conn.openInputStream(); os = conn.openOutputStream(); StringBuffer sb = new StringBuffer(); int c; while (!exit) { os.write("<html>\n".getBytes()); while ((c = is.read()) != -1) { sb.append((char) c); } System.out.println(sb.toString()); sb.delete(0, sb.length() - 1); try { Thread.sleep(1000); } catch (InterruptedException ex) { ex.printStackTrace(); } } os.close(); is.close(); conn.close(); } catch (IOException ex) { ex.printStackTrace(); } } I've tried InputStream.read, but it doesn't block either, it returns -1 as well. I'm trying to keep the I/O streams on either side alive. I want the servlet to wait for input, process the input, then send back a response. In the code above it should do this 20 times. thanks for any help
