  • strtod() and sprintf() inconsistency under GCC and MSVC

    - by Dmitry Sapelnikov
    I'm working on a cross-platform app for Windows and Mac OS X, and I have a problem with two standard C library functions: strtod() - string-to-double conversion sprintf() - when used for outputting double-precision floating point numbers) Their GCC and MSVC versions return different results. I'm looking for a well-tested cross-platform open-source implementation of those functions, or just for a pair of functions that would correctly and consistently convert double to string and back. I've already tried the clib GCC implementation, but the code is too long and too dependent on other source files, so I expect the adaptation to be difficult. What implementations of string-to-double and double-to-string functions would you recommend?

    I've a problem when i tried to count how many time a word appears into a txt file. 1/ I create a textfield ( txta ) 2/ I create a button to apply the action ( btn ) 3/ I create a textarea ( area ) that is the place where the content of the file is displayed When I select the file, the content of the file is displayed on area, then I enter the word in txta to search and then I clicked the btn but the code is not working public int contarPalabras(String chain, String word) { // Recibe un string y una palabra y devuelve la cantidad de veces que encontró esa palabra en el string. // Si no encuentra la letra devuelve (-1). int cant = 0; int intIndex = chain.indexOf(word); if(intIndex == - 1){ cant = -1; }else{ cant = intIndex; } return cant; }

  • Will this SQL screw up

    - by Joshua
    I'm sure everyone knows the joys of concurrency when it comes to threading. Imagine the following scenario on every page-load on a noobily set up MySQL db: UPDATE stats SET visits = (visits+1) If a thousand users load the page at same time, will the count screw up? is this that table locking/row locking crap? Which one mysql use.

  • Make a server for a chat

    - by Sebastian
    Hello, I would like to make a server for a chat and I wonder whether a server must, for example, connect to MySQL whenever a client enter to a room to check if he is moderator or banned from this room. Is it necessary that I use MySQL to update the number of connected clients whenever a client go to another room(to display the number of connected clients on a web page)?

  • Can I create my own database from PHP?

    - by Roman
    I have a working PHP server. Now I want to use databases (MySQL or something similar). Is it possible to create a database from PHP? I would like to emphasize that in my case I do not have any user-name and password to which I can use to connect to MySQL server. I also do not have a control-panel where I could create a database or a table in an existing database.

  • turning text into image - PHP/GD - save image

    - by Phil Jackson
    Hi, I'm using this script to simply create an image from text. What I would like to know is how to save the image instead of printing straight to browser; // an email address in a string $string = $post[$key]; // some variables to set $font = 4; $width = ImageFontWidth($font) * strlen($string); $height = ImageFontHeight($font); // lets begin by creating an image $im = @imagecreatetruecolor ($width,$height); //white background $background_color = imagecolorallocate ($im, 255, 255, 255); //black text $text_color = imagecolorallocate ($im, 0, 0, 0); // put it all together $image = imagestring ($im, $font, 0, 0, $string, $text_color); I know its probably just one line of code at the end but im not sure which GD function to use. Any help would be much appreciated, Regards, Phil.

  • Is there a generic way of dealing with varying connection strings in C#?

    - by James Wiseman
    I have an application that needs to connect to a SQL database, and execute a SQL Agent Job. The connection string I am trying to access is stored in the registry, which is easily enough pulled out. This appliction is to be run on multiple computers, and I cannot guarantee the format of this connection string being consistent across these computers. Two that I have pulled out for example are: Data Source=Server1;Initial Catalog=DB1;Integrated Security=SSPI; Data Source=Server2;Initial Catalog=DB1;Provider=SQLNCLI.1;Integrated Security=SSPI;Auto Translate=False; I can use an object of type System.Data.SqlClient.SqlConnection to connect to the database with the first connection string, howevever, I get the following error when I pass the second to it: keyword not supported: 'provider' Similarly, I can use the an object of type System.Data.OleDb.OleDbConnection to connect to the database with the second connection string, howevever, I get the following error when I pass the first to it: An OLEDB Provider was not specified in the ConnectionString' I can solve this by scanning the string for 'Provider' and doing the connect conditionally, however I can't help but feel that there is a better way of doing this, and handle the connection strings in a more generic fashion. Does anyone have any suggestions?

  • Date conversion in Java

    - by llm
    How can I take a string in a format such as: 2008-06-02 00:00:00.0 and convert it to: 02-Jun-2008? Can I somehow take the original string, convert it to a Date object, then use a formatter to get the final output (rather than parsing the string myself)? Thanks!

  • retrieving value from database in java

    - by Akcire Atienza
    I am making AGAIN another program that retrieves the inputted data/values of fields from the database I created. but this time, my inputted value will be coming from the JtextField I created. I wonder what's wrong in here bec when I'm running it the output is always null. in this program i will convert the inputted value of my JTextField into int. here it is: public class ButtonHandler implements ActionListener { public void actionPerformed(ActionEvent e) { if(e.getSource() == extendB) { ExtensionForm extend = new ExtensionForm(); extend.setVisible(true); } else if(e.getSource()== searchB) { //get text from the textField String guest = guestIDTF.getText(); //parse the string to integer for retrieving of data int id = Integer.parseInt(guest); GuestsInfo guestInfo = new GuestsInfo(id); Room roomInfo = new Room(id); String labels[] = {guestInfo.getFirstName()+" "+guestInfo.getLastName(),""+roomInfo.getRoomNo(),roomInfo.getRoomType(),guestInfo.getTime(),"11:00"}; for(int z = 0; z<labels.length; z++) { labelDisplay[z].setText(labels[z]); } in my second class it retrieves the inputted values of fields from the database I created here's the code: import java.sql.*; public class Room { private String roomType; private int guestID, roomNo; private Connection con; private PreparedStatement statement; public Room(){ try { Class.forName("com.mysql.jdbc.Driver"); con = DriverManager.getConnection( "jdbc:mysql://localhost:3306/3moronsdb","root",""); } catch (Exception e) { e.printStackTrace(); } } public Room(int guestsID) { this(); try{ statement = con.prepareStatement("SELECT * FROM guest WHERE guestID=?"); statement.setInt(1, guestID); ResultSet rs = statement.executeQuery(); while(rs.next()){ this.guestID = rs.getInt(1); this.roomType = rs.getString(2); this.roomNo = rs.getInt(3); } }catch(Exception e){ System.out.print(e); } } //Constructor for setting rate public Room(String roomType, int roomNo) { this(); try { statement = con.prepareStatement("Insert into room(roomType, roomNo) values(?,?)"); statement.setString(1, roomType); statement.setInt(2, roomNo); statement.executeUpdate(); } catch(Exception e) { e.printStackTrace(); return; } } //getting roomType public String getRoomType(){ return roomType; } //getting roomNo public int getRoomNo(){ return roomNo; } //getting guestID public int getGuestId(){ return guestID; } } i already insert some values in my 3moronsdb which are ( 1, Classic , 103). here's my TEST main class: public class TestMain { public static void main(String [] a){ GuestsInfo guest = new GuestsInfo(1); //note that this instantiation is the other class which i just ask the other day.. (http://stackoverflow.com/questions/12762835/retrieving-values-from-database-in-java) Room rum = new Room(1); System.out.print(rum.getRoomType()+" "+ guest.getFirstName()); } } when i'm running it it only gives me null output for the Room class but i am getting the output of the GuestsInfo class which is 'Ericka'. Can you help me guys? I know I ask this kind of problem yesterday but i really don't know what's wrong in here now..

  • Help with \0 terminated strings in C#

    I'm using a low level native API where I send an unsafe byte buffer pointer to get a c-string value.

  • javascript split() array contains

    - by Mahesha999
    While learning JavaScript, I did not get why the output when we print the array returned of the Sting.split() method (with regular expression as an argument) is as explained below. var colorString = "red,blue,green,yellow"; var colors = colorString.split(/[^\,]+/); document.write(colors); //this print 7 times comma: ,,,,,,, However when I print individual element of the array colors, it prints an empty string, three commas and an empty string: document.write(colors[0]); //empty string document.write(colors[1]); //, document.write(colors[2]); //, document.write(colors[3]); //, document.write(colors[4]); //empty string document.write(colors[5]); //undefined document.write(colors[6]); //undefined Then, why printing the array directly gives seven commas. Though I think its correct to have three commas in the second output, I did not get why there is a starting (at index 0) and ending empty string (at index 4). Please explain I am screwed up here.

  • How to lowercase every element of a collection efficiently?

    - by Chris
    Whats the most efficient way to lower case every element of a list or set? My idea for a List: final List<String> strings = new ArrayList<String>(); strings.add("HELLO"); strings.add("WORLD"); for(int i=0,l=strings.size();i<l;++i) { strings.add(strings.remove(0).toLowerCase()); } is there a better, faster way? How would this exmaple look like for a set? As there is currently no method for applying an operation to each element of a set (or list) can it be done without creating an additional temporary set? Something like this would be nice: Set<String> strings = new HashSet<String>(); strings.apply( function (element) { this.replace(element, element.toLowerCase();) } ); Thanks,

  • Newline not showing correctly in textbox

    - by TheGateKeeper
    I am loading a string from my database which among other things contains line breaks (\r\n). However, this isn't being rendered as a new line but instead as \r\n. If I type it directly in instead of loading it from a string, it works just fine but I need to be able to load it from a string. Any ideas? Edit: Upon closer inspection, it looks like the string is being returned as: Changed test7\\r\\nChanged test8\\r\\nChanged test9Changed test7 From the database. I tried running a .Replace(@"\\", @"\") on it but this had no effect at all. Any ideas?
