  • PHP login, getting wrong count value from query / fetch array

    - by Chris
    Hello, *EDIT*Thanks to the comments below it has been figured out that the problem lies with the md5, without everything works as it should. But how do i implent the md5 then? I am having some troubles with the following code below to login. The database and register system are already working. The problem lies that it does not find any result at all in the query. IF the count is 0 it should redirect the user to a secured page. But this only works if i write count = 0, but this should be 0 , only if the user name and password is found he should be directed to the secure (startpage) of the site after login. For example root (username) root (password) already exists but i cannot seem to properly login with it. <?php session_start(); if (!empty($_POST["send"])) { $username = ($_POST["username"]); $password = (md5($_POST["password"])); $count = 0; $con = mysql_connect("localhost" , "root", ""); mysql_select_db("testdb", $con); $result = mysql_query("SELECT name, password FROM user WHERE name = '".$username."' AND password = '".$password."' ") or die("Error select statement"); $count = mysql_num_rows($result); if($count > 0) // always goes the to else, only works with >=0 but then the data is not found in the database, hence incorrect { $row = mysql_fetch_array($result); $_SESSION["username"] = $row["name"]; header("Location: StartPage.php"); } else { echo "Wrong login data, please try again"; } mysql_close($con); } ?>

  • Efficient retrieval of lists over WebServices

    - by Chris
    I have a WCF WebService that uses LINQ and EF to connect to an SQL database. I have an ASP.NET MVC front end that collects its data from the webservice. It currently has functions such as List<Customer> GetCustomers(); As the number of customers increases massively the amount of data being passed increases also reducing efficiency. What is the best way to "page data" across WebServices etc. My current idea is to implement a crude paging system such as List<Customer> GetCustomers(int start, int length); This, however, means I would have to replicate such code for all functions returning List types. It is unfortunate that I cannot use LINQ as it would be much nicer. Does anyone have any advice or ideas of patterns to implement that would be "as nice as possible" Thanks

  • What is the most efficient way to handle points / small vectors in JavaScript?

    - by Chris
    Currently I'm creating an web based (= JavaScript) application thata is using a lot of "points" (= small, fixed size vectors). There are basically two obvious ways of representing them: var pointA = [ xValue, yValue ]; and var pointB = { x: xValue, y: yValue }; So translating my point a bit would look like: var pointAtrans = [ pointA[0] + 3, pointA[1] + 4 ]; var pointBtrans = { x: pointB.x + 3, pointB.y + 4 }; Both are easy to handle from a programmer point of view (the object variant is a bit more readable, especially as I'm mostly dealing with 2D data, seldom with 3D and hardly with 4D - but never more. It'll allways fit into x,y,z and w) But my question is now: What is the most efficient way from the language perspective - theoretically and in real implementations? What are the memory requirements? What are the setup costs of an array vs. an object? ... My target browsers are FireFox and the Webkit based ones (Chromium, Safari), but it wouldn't hurt to have a great (= fast) experience under IE and Opera as well...

  • Fast compiler error messages in Eclipse

    - by Chris Conway
    As a new Eclipse user, I am constantly annoyed by how long it takes compiler error messages to display. This is mostly only a problem for long errors that don't fit in the status bar or the "Problems" tab. But I get enough long errors in Java—especially with generics—that this is a nagging issue. (Note: The correct answer to this question is not "get better at using generics." ;-) The ways I have found to display an error are: Press Ctrl+. or execute the command "Next Annotation". The next error is highlighted and its associated message appears in the status bar (if it is short enough). The error is also highlighted in the "Problems" tab, if it is open, but the tab is not automatically brought to the top. Hover the mouse over the error. After a noticeable lag, the error message appears as a "tool tip", along with any associated "Quick Fixes." Hover the mouse over the error icon on the left side of the editing pane. After a noticeable lag, all of the error messages for that line appear as a "tool tip." Clicking on the icon brings up "Quick Fixes." What I would like is for Ctrl+. to automatically and instantly bring up the complete error message (I don't care where). Is this a configurable option? [UPDATE] @asterite's "Ctrl+. F2" is almost it. How do I make "Next Annotation, then Show Tooltip Description" a macro bound to a single keystroke?

  • LINQ Query based on user preferences

    - by Chris Phelps
    How can I do this better (so it actually works : ) I have a LINQ Query that includes an order by that is based on a user preference. The user can decide if they would like the results ordered asc or desc. If fuserclass.SortOrder = "Ascending" Then Dim mydat = (From c In dc.ITRS Order By c.Date Ascending Select c) Else Dim mydat = (From c In dc.ITRS Order By c.Date Descending Select c) End If For each mydata in mydat ***<<<error "mydat is not declared"*** I know I could put my For Each loop inside the If and Else, but that seems silly to have the same code twice. I know you know of a better way : )

    I have a ListView in WPF, and I want to hide the headers for the ListView when the List the ItemsSource is bound to is null, and display the headers when the ItemsSource is not null and has at least 1 item in the collection.

  • FLV Player Skin Custom URL

    - by Chris
    I have a flash banner ad (AS3) which uses a FLV Player component for a remove video. The Skin exports it's own SWF file for user with the video controls as I'm sure anyone familiar with Flash knows. Is there anyway to specify where this file is remotely? I have to provide 1 file to my advertiser, and do not want to have to create custom video controls for this. Is it possible to upload this swf file to a remote location and tell Flash to pull it from there? Any help would be greatly appreciated.

  • Obtaining XML from U.S. Postal Service (USPS) rate calculator API with PHP

    - by Chris F
    hoping somebody here can help me. I'm attempting to pull an XML page from the U.S. Postal Service (USPS) rate calculator, using PHP. Here is the code I am using (with my API login and password replaced of course): <? $api = "http://production.shippingapis.com/ShippingAPI.dll?API=RateV4&XML=<RateV4Request ". "USERID=\"MYUSERID\" PASSWORD=\"MYPASSWORD\"><Revision/><Package ID=\"1ST\">". "<Service>FIRST CLASS</Service><FirstClassMailType>PARCEL</FirstClassMailType>". "<ZipOrigination>12345</ZipOrigination><ZipDestination>54321</ZipDestination>". "<Pounds>0</Pounds><Ounces>9</Ounces><Container/><Size>REGULAR</Size></Package></RateV4Request>"; $xml_string = file_get_contents($api); $xml = simplexml_load_string($xml_string); ?> Pretty straightforward. However it never returns anything. I can paste the URL directly into my browser's address bar: http://production.shippingapis.com/ShippingAPI.dll?API=RateV4&XML=<RateV4RequestUSERID="MYUSERID" PASSWORD="MYPASSWORD"><Revision/><Package ID="1ST"><Service>FIRST CLASS</Service><FirstClassMailType>PARCEL</FirstClassMailType><ZipOrigination>12345</ZipOrigination><ZipDestination>54321</ZipDestination><Pounds>0</Pounds><Ounces>9</Ounces><Container/><Size>REGULAR</Size></Package></RateV4Request> And it returns the XML I need, so I know the URL is valid. But I cannot seem to capture it using PHP. Any help would be tremendously appreciated. Thanks in advance.

  • [MS Access 2003 SQL] Switch is causing #error, why and how can I fix it...

    - by Chris
    I have 3 fields in my table: start, end (dates) and length (number, might be blank). My Aim is to calculate an end date using start and length where end doesn't exist... I have: SELECT Switch((g.length<>0) And IsDate(g.end),DateAdd("m",g.length,g.start)) AS field FROM table g If there is no start, end or length, Access displays blank - this is fine. If there is no end, but start and length are ok, the calculated date is shown - again fine. BUT If there is no end, or length, but a start exists, access displays #Error I don't understand why, and can't fix it, please help!

  • Keeping object in memory (iPhone SDK)

    - by Chris
    I am trying to create a UIImageView called theImageView in the touchesBegan method that I can then then move to a new location in touchesMoved. Currently I am receiving an "undeclared" error in touchesMoved where I set the new location for theImageView. What can I do to keep theImageView in memory between these two methods? - (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { ... UIImageView *theImageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"image.png"]]; theImageView.frame = CGRectMake(263, 228, 193, 300); [theImageView retain]; ... } - (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event { ... theImageView.frame = CGRectMake(300, 300, 193, 300); ... }

  • Rails: bi-directional has_many :through relationship

    - by Chris
    I have three models in a Rails application: Game represents an instance of a game being played. Player represents an instance of a participant in a game. User represents a registered person who can participate in games. Each Game can have many Players, and each User can have many Players (a single person can participate in multiple games at once); but each Player is in precisely one Game, and represents precisely one User. Hence, my relationships are as follows at present. class Game has_many :players end class User has_many :players end class Player belongs_to :game belongs_to :user end ... where naturally the players table has game_id and user_id columns, but games and users have no foreign keys. I would also like to represent the fact that each Game has many Users playing in it; and each User has many Games in which they are playing. How do I do this? Is it enough to add class Game has_many :users, :through => :players end class User has_many :games, :through => :players end

  • ANDROID SAX Parser issue

    - by Chris Watson
    Since I am new to java programming, I need a bit of help with this. I stuck on this one issue and can't continue until I get this to work. I am trying to make a string from that includes a preference int. I saved the data and can display the int (just sample code): SharedPreferences prefs=PreferenceManager .getDefaultSharedPreferences(this); list.setText(prefs.getString("list", "22")); now, I have a xml parser that is pulling a url correctly as a static string: public static String feedUrl = String.format("http://www.freshpointmarketing.com/iphone/objects/XML/AND.php?ID=%d", 22); Works great... now my issue...... I need to have the preference "int" become the variable in the string, thus making it not static. static SharedPreferences prefs=PreferenceManager.getDefaultSharedPreferences(this); static int myVariable = prefs.getInt("list1", 22); public static String feedUrl = String.format("http://www.freshpointmarketing.com/iphone/objects/XML/AND.php?ID=%d", myVariable); If I take out all static references, I get an error on this: private void loadFeed(ParserType type){ try{ FeedParser parser = FeedParserFactory.getParser(type); long start = System.currentTimeMillis(); messages = parser.parse(); long duration = System.currentTimeMillis() - start; Log.i("AndroidNews", "Parser duration=" + duration); String xml = writeXml(); Log.i("AndroidNews", xml); List<String> titles = new ArrayList<String>(messages.size()); for (Message msg : messages){ titles.add(msg.getTitle()); } ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, R.layout.row,titles); this.setListAdapter(adapter); } catch (Throwable t){ Log.e("AndroidNews",t.getMessage(),t); } } thanks

  • CodeIgniter - Returning multiple file upload details

    - by Chris
    Hey All, Im using the codeigniter upload library to upload multiple files, which works fine ... What im having problems with is returning the information about the files. Im using the following code to print the results for testing echo '<pre>'; print_r($this->upload->data()); echo '</pre>'; A cut down version of the results are as follows Array ( [file_name] => Array ( [0] => filename1.gif [1] => filename2.jpg ) ) The way my view is setup, is that i use jquery to insert multiple dynamic file input fields so the amount of files can be 1, it can be 50 and so on. Im wondering how i would loop through that array to send each filename to the database

  • TSQL - create a stored proc inside a transaction statement

    - by Chris L
    I have a sql script that is set to roll to production. I've wrapped the various projects into separate transactions. In each of the transactions we created stored procedures. I'm getting error messages Msg 156, Level 15, State 1, Line 4 Incorrect syntax near the keyword 'procedure'. I created this example script to illustrate Begin Try Begin Transaction -- do a bunch of add/alter tables here -- do a bunch of data manipulation/population here -- create a stored proc create procedure dbo.test as begin select * from some_table end Commit End Try Begin Catch Rollback Declare @Msg nvarchar(max) Select @Msg=Error_Message(); RaisError('Error Occured: %s', 20, 101,@Msg) With Log; End Catch The error seems to imply that I can't create stored procs inside of transaction, but I'm not finding any docs that say otherwise(maybe google isn't being freindly today).

  • In PHP can I check a boolean on a function call?

    - by Chris
    I have a function which checks the passed value and returns false or true, if false I want it to add something to an array. The code I've written is below. if(!check_input($_POST['username'])){ $errors[] = "Username"; } Right now it adds to my array anyway, regardless of what is entered in the form. Is the way I've written that the correct way to check if the return from check_input() is false? I've checked the function's logic by altering the returns to echoes and it's returning the correct value, I'm just not sure if I'm checking it wrong. I'd previously attempted to write it as $X=check_input etc, and then if(check_value == false) but that doesn't seem to give me the desired result either. Hmmm a quick pointer please!

  • What's the easiest way to create an extensible custom container in Flex?

    - by Chris R
    I want to create an MXML container component that has some of its own chrome -- a standard query display, et al -- and that supports the addition of child components to it. Something a lot like the existing mx:Panel class, which includes a title label, but acts like a plain mx:Box with regards to adding children. What's the easiest way to do this? Edit: To be clear, I want to be able to extend the container using MXML, so the "Multiple visual children" problem is relevant.

  • Wordpress Hooks vs. includes?

    - by Chris J. Lee
    This is somewhat a subjective question. Noticed themes like thematic and carrington use hooks to display their themes. Trying to figure out which works best for a more efficient workflow. Which seems more efficient at theming? Trying to weigh in the cons and pros of hooks vs. just including static files.

  • PHP download page: file_exists() returns true, but browser returns 'page not found'

    - by Chris
    I'm using PHP for a file download page. Here's a snippet of the problem code: if (file_exists($attachment_location)) { header($_SERVER["SERVER_PROTOCOL"] . " 200 OK"); header("Cache-Control: public"); // needed for i.e. header("Content-Type: application/zip"); header("Content-Transfer-Encoding: Binary"); header("Content-Length:".filesize($attachment_location)); header("Content-Disposition: attachment; filename=file.zip"); readfile($attachment_location); die("Hooray"); } else { die("Error: File not found."); } This code works absolutely fine when testing locally, but after deploying to the live server the browser returns a 'Page not found' error. I thought it might be an .htaccess issue, but all .htaccess files on the live server are identical to their local counterparts. My next guess would be the live server's PHP configuration, but I have no idea what PHP setting might cause this behaviour. The file_exists() function always returns true - I've checked this on the live server and it's always correctly picking up the file, its size etc., so it does have a handle on the file. It just won't perform the download! The main site is a Wordpress site, but this code isn't part of a Wordpress page - it's in a standalone directory within the site root. UPDATE: is_file() and is_readable() are both returning true for the file, so that's not the problem. The specific line that is causing the problem is: readfile($attachment_location) Everything up until that point is super happy.
