  • PDO empy result from SELECT when using AND

    - by Jurgen
    Hello, I've come upon a rather interesting thing, which I can't seem to figure out myself. Everytime when executing a SQL statement which contains a '... AND ...' the result is empty. Example: echo('I have a user: ' . $email . $wachtwoord . '<br>'); $dbh = new PDO($dsn, $user, $password); $sql = 'SELECT * FROM user WHERE email = :email AND wachtwoord= :wachtwoord'; $stmt = $dbh->prepare($sql); $stmt->bindParam(:email,$email,PDO::PARAM_STR); $stmt->bindParam(:wachtwoord,$wachtwoord,PDO::PARAM_STR); $stmt->execute(); while($row = $stmt->fetchObject()) { echo($row-email . ',' . $row-wachtwoord); $user[] = array( 'email' = $row-email, 'wachtwoord' = $row-wachtwoord ); } The first echo displays the correct values, however the line with echo($row->email . ',' . $row->wachtwoord); is never reached. A few things I want to add: 1) I am connected to the database since other queries work, only the ones where I add an 'AND' after my 'WHERE's fail. 2) Working with the while works perfectly with queries that do not contain '... AND ...' 3) Error reporting is on, PDO gives no exceptions on my query (or anything else) 4) Executing the query directly on the database does give what I want: SELECT * FROM user WHERE email = '[email protected]' AND wachtwoord = 'jurgen' I can stare at it all day long again (which I already did once, but I managed to work around the 'AND'), but maybe one of you can give me a helping hand. Thank you in advance. Jurgen

  • How can I prevent a textbox from taking focus on the postback when I have a calendar extender on it?

    - by Biff MaGriff
    Hello, I have repeater, inside this repeater is a user control. In my c# codebehind on my user control I dynamically add a textbox and assign a calendar extender to it. Similar to this. //custom control protected void Page_Load(object o, EventArgs e) { TextBox tb = new TextBox(); tb.ID = "myTextBox"; MaskedEditExtender meeDate = new MaskedEditExtender(); meeDate.ID = "meeDate"; meeDate.TargetControlID = this.UniqueID + "$" + tb.ID; meeDate.Mask = "99/99/9999"; meeDate.MaskType = MaskedEditType.Date; CalendarExtender ce = new CalendarExtender(); ce.ID = "ceCalendar"; ce.TargetControlID = this.UniqueID + "$" + tb.ID; this.Controls.Add(tbDate); this.Controls.Add(meeDate); this.Controls.Add(ce); } This works well, however after I postback the textbox takes focus and the calendar extender fires and it looks really.... dumb. How can I stop this?

  • Mysql issue with decimal

    - by azz0r
    Hello, I have two fields - amount (decimal (11, 2)) - gift_amount (decimal (11, 2)) When I do an update on either for a value equal to or below 999.99, it saves correctly. However, if I go over that, then it drops the value right back to down 1 - 10. Is this a known issue or am I going wrong using decimal? Heres some PHP code of what I'm doing just to make it clearer (although I'm 100% its not the PHP's fault. if ($total_balance >= $cost) { if ($this->user->balance->gift_amount > 0) { $total_to_be_paid = number_format($cost, 2) - number_format($this->user->balance->gift_amount, 2);//figure out how much is left after the gift total $this->user->balance->gift_amount -= number_format($cost, 2); //deduct from the gift balance $this->user->balance->gift_amount = (number_format($this->user->balance->gift_amount, 2) < 0) ? number_format(00.00, 2) : number_format($this->user->balance->gift_amount, 2); //if the gift balance went below 0, lets set it to 0 if ($total_to_be_paid > 0) { $this->user->balance->amount = number_format($this->user->balance->amount, 2) - number_format($total_to_be_paid, 2); } } else { $this->user->balance->amount = number_format($this->user->balance->amount, 2) - number_format($cost, 2); } if ($object = Model_ClipBought::create(array('clip_id' => $clip->id, 'user_id' => $this->user->id, 'currency_name' => $user_currency, 'cost' => $cost, 'downloads' => $clip->downloads, 'expires' => time() + ($clip->expires * 86400)))) { $this->user->balance->save(); $download = new Model_Download(ROOT_PATH."/public/files/Clip/$clip->file_url"); $download->execute(); } else { throw new exception('We could not finish the purchase, this has been reported, sorry for the inconvenience.'); } } else { throw new exception('You dont have enough money in your account todo this'); } exit; }

  • Loading the target of a link in a <DIV> via jQuery's .live event into the same <DIV>??

    - by Martin Pescador
    Hello together I call a certain div from another page with jquery to be loaded into a div on my main page like this: <script type="text/javascript"> $("#scotland").load("http://www.example.com/scotland .gallery"); </script> <div id="scotland"></div> The div I call is a piece of code which is automatically generated by a CMS made simple module, by the way. Now it comes to my problem: The .gallery div I call, looks, a little simplified, like this: <div class="gallery"> <span><img src="http://www.example.com/scotlandimage1.jpg"></span> <span class="imgnavi"><a href="link_to_next_page_with_one_image">Next image</href></span> </div> I want the "next image"-link to load the next page into the .gallery div (it is always a page with one image on it). But what it does, is, it opens the new page http://www.example.com/scotland only. I tried to use jquerys .live event to load the linked page (that would be "scotlandimage2" and the navigation, as you can see in the upper part - not only the image!), but I must have done something wrong. I tried different ways, but never got it to work. This was my last try: $(".imgnavi a").click(function() { var myUrl = $(this).attr("href"); $(".gallery").load(myUrl); return false; }); I have to admit that I am very new to jquery... But does someone know what I did wrong (do I even follow the right handlers?)? Thanks very much in advance! Martin

  • Which is the best free ide/plugin for struts2?

    - by Shahensha
    Hello friends, I have just learnt struts 2 and now I have taken up a full fledged project in it. I learnt the basics of struts 2 in Netbeans with it's struts2 plugin. But I am not at all happy with it, as it is very basic and I end up doing most of the work. It is obviously better than plain-vanilla text editor, but still not at all near to what netbeans provides for springs and hibernate. I know because netbeans provides native support for springs and hibernate, it is meant to be better. I don't mind changing my IDE if i get better support for struts2! So my questions are Please list all the free IDEs where native support for struts2 is provided. And if possible please compare them. Please list all the plugins that are available for eclipse for struts2 development. I have heard there are better plugins in eclipse. Also, if there are better plugins in any other IDE (other than netbeans or eclipse of course), please list them giving links. Please give me some tips which I'll need before starting a full blown project in Struts2. I haven't worked on any project on Struts2. I have just finished reading Struts 2 in Action of Manning publications. Thanking you in advance! regards shahensha

  • A way for a file to have its own MD5 inside? Or a string that is it's own MD5?

    - by Eli
    Hi all, In considering several possible solutions to a recent task, I found myself considering how to get a php file that includes it's own MD5 hash. I ended up doing something else, but the question stayed with me. Something along the lines of: <?php echo("Hello, my MD5 is [MD5 OF THIS FILE HERE]"); ?> Whatever placeholder you have in the file, the second you take its MD5 and insert it, you've changed it, which changes it's MD5, etc. Edit: Perhaps I should rephrase my question: Does anyone know if it has been proven impossible, or if there has been any research on an algorithm that would result in a file containing it's own MD5 (or other hash)? I suppose if the MD5 was the only content in the file, then the problem can be restated as how to find a string that is it's own MD5. It may well be impossible for us to create a process that will result in such a thing, but I can't think of any reason the solution itself can't exist. The question is basically whether it really is impossible, simply improbable (on the order of monkeys randomly typing Shakespeare), or actually solvable by somebody smarter than myself.

  • HTML Calendar form and input arrays

    - by Christopher Ickes
    Hello. Looking for the best practice here... Have a form that consists of a calendar. Each day of the calendar has 2 text input fields - customer and check-in. What would be the best & most efficient way to send this form to PHP for processing? <form action="post"> <div class="day"> Day 1<br /> <label for="customer['.$current['date'].']">Customer</label> <input type="text" name="customer['.$current['date'].']" value="" size="20" /> <label for="check-in['.$current['date'].']">Check-In</label> <input type="text" name="check-in['.$current['date'].']" value="" size="20" /> <input type="submit" name="submit" value="Update" /> </day> <div class="day"> Day 2<br /> <label for="customer['.$current['date'].']">Customer</label> <input type="text" name="customer['.$current['date'].']" value="" size="20" /> <label for="check-in['.$current['date'].']">Check-In</label> <input type="text" name="check-in['.$current['date'].']" value="" size="20" /> <input type="submit" name="submit" value="Update" /> </day> </form> Is my current setup good? I feel there has to be a better option. My concern involves processing a whole year at once (which can happen) and adding additional text input fields.

  • Implementing Operator Overloading with Logarithms in C++

    - by Jacob Relkin
    Hello my friends, I'm having some issues with implementing a logarithm class with operator overloading in C++. My first goal is how I would implement the changeBase method, I've been having a tough time wrapping my head around it. My secoond goal is to be able to perform an operation where the left operand is a double and the right operand is a logarithm object. Here's a snippet of my log class: // coefficient: double // base: unsigned int // number: double class _log { double coefficient, number; unsigned int base; public: _log() { base = rand(); coefficient = rand(); number = rand(); } _log operator+ ( const double b ) const; _log operator* ( const double b ) const; _log operator- ( const double b ) const; _log operator/ ( const double b ) const; _log operator<< ( const _log &b ); double getValue() const; bool changeBase( unsigned int base ); }; You guys are awesome, thank you for your time.

  • What harm can javascript do?

    - by The King
    I just happen to read the joel's blog here... So for example if you have a web page that says “What is your name?” with an edit box and then submitting that page takes you to another page that says, Hello, Elmer! (assuming the user’s name is Elmer), well, that’s a security vulnerability, because the user could type in all kinds of weird HTML and JavaScript instead of “Elmer” and their weird JavaScript could do narsty things, and now those narsty things appear to come from you, so for example they can read cookies that you put there and forward them on to Dr. Evil’s evil site. Since javascript runs on client end. All it can access or do is only on the client end. It can read informations stored in hidden fields and change them. It can read, write or manipulate cookies... But I feel, these informations are anyway available to him. (if he is smart enough to pass javascript in a textbox. So we are not empowering him with new information or providing him undue access to our server... Just curious to know whether I miss something. Can you list the things that a malicious user can do with this security hole. Edit : Thanks to all for enlightening . As kizzx2 pointed out in one of the comments... I was overlooking the fact that a JavaScript written by User A may get executed in the browser of User B under numerous circumstances, in which case it becomes a great risk.

  • Refresh a Div that has a Google ad inside it

    - by Abs
    Hello all, I have a div that holds a google ad. My website is mostly AJAX and there is no need for a browser refresh. That means my ads will not refresh either, which isnt ideal, a user staring at one ad all day. So I wanted a way to refresh a particular div on a page. I found many solutions but they didnt work. For example, using JQuery's html function: $("#ads").html("google ad script here"); This managed to refresh the whole page no idea how. I can also make an AJAX request to a HTML page that contains the google ad but I am guessing it will have the same effect as the above attempt. I do not want to use iFrames. Is there any other option open to me? My pea brain can not think of anymore. :) Thanks you for any help. EDIT: It is allowed since I will be initiating the refresh only when a user clicks a link. A prime example is Yahoo Mail - their new AJAX mailbox uses this same method, when a user clicks a link then a new ad is shown.

  • How to get a volume measurement of iPhone recording in dB, with a limit of at least 120dB

    - by Cyber
    Hello, I am trying to make a simple volume meter for the iPhone. I want the volume displayed in dB. When using this turorial, I am only getting measurements up to 78 dB. I've read that that is because the dBFS spectrum for 16 bit audio recordings is only 96 dB. I tried modifying this piece of code in the init funcyion: dataFormat.mSampleRate = 44100.0f; dataFormat.mFormatID = kAudioFormatLinearPCM; dataFormat.mFramesPerPacket = 1; dataFormat.mChannelsPerFrame = 1; dataFormat.mBytesPerFrame = 2; dataFormat.mBytesPerPacket = 2; dataFormat.mBitsPerChannel = 16; dataFormat.mReserved = 0; I changed the value of mBitsPerChannel, hoping to increase the bit value of the recording. dataFormat.mBitsPerChannel = 32; With that variable set to 32, the "mAveragePower" function returns only 0. So, how can i measure more decibels? All my code is practically the same as in the tutorial i posted above. Thanks in advance, Thomas

  • MySQL ORDER BY DESC is fast but ASC is very slow

    - by Pepper
    Hello, I'm completely stumped on this one. For some reason when I sort this query by DESC it's super fast, but if sorted by ASC it's extremely slow. This takes about 150 milliseconds: SELECT posts.id FROM posts USE INDEX (published) WHERE posts.feed_id IN ( 4953,622,1,1852,4952,76,623,624,10 ) ORDER BY posts.published DESC LIMIT 0, 50; This takes about 32 seconds: SELECT posts.id FROM posts USE INDEX (published) WHERE posts.feed_id IN ( 4953,622,1,1852,4952,76,623,624,10 ) ORDER BY posts.published ASC LIMIT 0, 50; The EXPLAIN is the same for both queries. id select_type table type possible_keys key key_len ref rows Extra 1 SIMPLE posts index NULL published 5 NULL 50 Using where I've tracked it down to "USE INDEX (published)". If I take that out it's the same performance both ways. But the EXPLAIN shows the query is less efficient overall. id select_type table type possible_keys key key_len ref rows Extra 1 SIMPLE posts range feed_id feed_id 4 \N 759 Using where; Using filesort And here's the table. CREATE TABLE `posts` ( `id` int(20) NOT NULL AUTO_INCREMENT, `feed_id` int(11) NOT NULL, `post_url` varchar(255) NOT NULL, `title` varchar(255) NOT NULL, `content` blob, `author` varchar(255) DEFAULT NULL, `published` int(12) DEFAULT NULL, `updated` datetime NOT NULL, `created` datetime NOT NULL, PRIMARY KEY (`id`), UNIQUE KEY `post_url` (`post_url`,`feed_id`), KEY `feed_id` (`feed_id`), KEY `published` (`published`) ) ENGINE=InnoDB AUTO_INCREMENT=196530 DEFAULT CHARSET=latin1; Is there a fix for this?

    Hello, A user reports that one of our applications doesn't work under WINE. It runs until he proceeds past a certain form, and then freezes. WINE gives the following output: ~/.wine/drive_c/HeroLab$ wine HeroLab.exe fixme:wininet:InternetSetOptionW Option INTERNET_OPTION_CONNECT_TIMEOUT (30000): STUB fixme:wininet:InternetSetOptionW INTERNET_OPTION_SEND/RECEIVE_TIMEOUT 30000 fixme:wininet:InternetSetOptionW Option INTERNET_OPTION_CONNECT_TIMEOUT (30000): STUB fixme:wininet:InternetSetOptionW INTERNET_OPTION_SEND/RECEIVE_TIMEOUT 30000 fixme:wininet:InternetSetOptionW Option INTERNET_OPTION_CONNECT_TIMEOUT (30000): STUB fixme:wininet:HTTPREQ_QueryOption Semi-STUB INTERNET_OPTION_SECURITY_FLAGS: 0 fixme:wininet:InternetSetOptionW Option INTERNET_OPTION_SECURITY_FLAGS; STUB fixme:wininet:InternetSetOptionW Option INTERNET_OPTION_CONNECT_TIMEOUT (30000): STUB fixme:wininet:InternetSetOptionW INTERNET_OPTION_SEND/RECEIVE_TIMEOUT 30000 fixme:wininet:InternetSetOptionW Option INTERNET_OPTION_CONNECT_TIMEOUT (30000): STUB fixme:wininet:InternetSetOptionW INTERNET_OPTION_SEND/RECEIVE_TIMEOUT 30000 fixme:wininet:InternetSetOptionW Option INTERNET_OPTION_CONNECT_TIMEOUT (30000): STUB fixme:wininet:InternetSetOptionW Option INTERNET_OPTION_CONNECT_TIMEOUT (30000): STUB fixme:wininet:InternetSetOptionW INTERNET_OPTION_SEND/RECEIVE_TIMEOUT 30000 fixme:wininet:InternetSetOptionW Option INTERNET_OPTION_CONNECT_TIMEOUT (30000): STUB fixme:wininet:InternetSetOptionW INTERNET_OPTION_SEND/RECEIVE_TIMEOUT 30000 fixme:wininet:InternetSetOptionW Option INTERNET_OPTION_CONNECT_TIMEOUT (30000): STUB fixme:bitmap:CreateBitmapIndirect planes = 0 fixme:bitmap:CreateBitmapIndirect planes = 0 fixme:bitmap:CreateBitmapIndirect planes = 0 fixme:bitmap:CreateBitmapIndirect planes = 0 fixme:bitmap:CreateBitmapIndirect planes = 0 fixme:bitmap:CreateBitmapIndirect planes = 0 fixme:bitmap:CreateBitmapIndirect planes = 0 fixme:bitmap:CreateBitmapIndirect planes = 0 fixme:bitmap:CreateBitmapIndirect planes = 0 fixme:bitmap:CreateBitmapIndirect planes = 0 fixme:bitmap:CreateBitmapIndirect planes = 0 Can anyone explain these messages to me? I assume they are messages from WINE reporting that we are calling functions in ways that WINE doesn't support, but our code doesn't call CreateBitmapIndirect at all. How can we locate the source of this problem, and fix our app so it runs under WINE? Thanks.

  • iPhone: objc_class_name_TTTabStrip symbol not found build error

    - by user187532
    Hello friends, I am trying to implement 'scrollview' effect in 'Tabbar' which has 'TabItems'. I found that the good example is from 'facebook' open source 'TTCatlog' project 'Tabs' section. So i included all the source from it to my project and trying to build it. I have followed the following links to go ahead on this: http://stackoverflow.com/questions/822792/how-to-create-a-horizontal-scrolling-view-on-iphone source: http://github.com/facebook/three20/tree/master/samples/ My calling code is like below: _tabBar1 = [[TTTabStrip alloc] initWithFrame:CGRectMake(10, 68, 300, 28)]; _tabBar1.tabItems = [NSArray arrayWithObjects: [[[TTTabItem alloc] initWithTitle:@"Item 1"] autorelease], [[[TTTabItem alloc] initWithTitle:@"Item 2"] autorelease], [[[TTTabItem alloc] initWithTitle:@"Item 3"] autorelease], [[[TTTabItem alloc] initWithTitle:@"Item 4"] autorelease], [[[TTTabItem alloc] initWithTitle:@"Item 5"] autorelease], [[[TTTabItem alloc] initWithTitle:@"Item 6"] autorelease], [[[TTTabItem alloc] initWithTitle:@"Item 7"] autorelease], [[[TTTabItem alloc] initWithTitle:@"Item 8"] autorelease], [[[TTTabItem alloc] initWithTitle:@"Item 9"] autorelease], [[[TTTabItem alloc] initWithTitle:@"Item 10"] autorelease], nil]; [self.navigationController.view addSubview:_tabBar1]; My project folder as like below: ..../iphone/MyProgram/MyProgram.xcodeproj ..../iphone/Three20/src/Three20.... In my project settings for header search path, I have ../Three20/src But when i try to build it, it throws the following error: "objc_class_name_TTTabStrip symbol not found" "objc_class_name_TTTabItem symbol not found" I see there, all these files (.h and .m) are availbale there. Could someone please help what's wrong there and how do i get rid of this issue and continue working with it?

  • As a newbie, where should I go if I want to create a small GUI program?

    - by jimbmk
    Hello, I'm a newbie with a little experience writing in BASIC, Python and, of all things, a smidgeon of assembler (as part of a videogame ROM hack). I wanted to create small tool for modifying the hex values at particular points, in a particular file, that would have a GUI interface. What I'm looking for is the ability to create small GUI program, that I can distribute as an EXE (or, at least a standalone directory). I'm not keen on the idea of the .NET languages, because I don't want to force people to download a massive .NET framework package. I currently have Python with IDLE and Boa Constructor set up, and the application runs there. I've tried looking up information on compiling a python app that relies on Wxwidgets, but the search results and the information I've found has been confusing, or just completely incomprehensible. My questions are: Is python a good language to use for this sort of project? If I use Py2Exe, will WxWidgets already be included? Or will my users have to somehow install WxWidgets on their machines? Am I right in thinking at Py2Exe just produces a standalone directory, 'dist', that has the necessary files for the user to just double click and run the application? If the program just relies upon Tkinter for GUI stuff, will that be included in the EXE Py2Exe produces? If so, are their any 'visual' GUI builders / IDEs for Python with only Tkinter? Thankyou for your time, JBMK

  • Calling a .net webservice from a plain HTML site using jQuery

    - by pwee167
    Hi guys, I wanted to know it is possible to call a hosted .net web service from a HTML page using jQuery? I tried this piece of code, but it doesn't work for me: $('#myForm').click(function() { $.ajax({ type: "POST", data: '{}', url: "http://localhost:49590/Service.asmx?op=HelloWorld", contentType: "application/json; charset=utf-8", dataType: "json", success: function(response) { alert(response.d); }, failure: function(result) { alert(result.status + ' ' + result.statusText); } }); }); And the webservice is as such: [WebService(Namespace = "http://tempuri.org/")] [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)] [System.ComponentModel.ToolboxItem(false)] // To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line. [System.Web.Script.Services.ScriptService] public class Service : System.Web.Services.WebService { [WebMethod] public string HelloWorld() { return "Hello World"; } } I have searched for this and found only examples where it is done from asp.net or asp.net mvc projects. I am not sure what I am missing but I thought this was possible from a plain HTML site with javascript, so can someone please point me in the right direction. Cheers!

  • Algorithm to detect how many words typed, also multi sentence support (Java)

    - by Alex Cheng
    Hello all. Problem: I have to design an algorithm, which does the following for me: Say that I have a line (e.g.) alert tcp 192.168.1.1 (caret is currently here) The algorithm should process this line, and return a value of 4. I coded something for it, I know it's sloppy, but it works, partly. private int counter = 0; public void determineRuleActionRegion(String str, int index) { if (str.length() == 0 || str.indexOf(" ") == -1) { triggerSuggestionList(1); return; } //remove duplicate space, spaces in front and back before searching int num = str.trim().replaceAll(" +", " ").indexOf(" ", index); //Check for occurances of spaces, recursively if (num == -1) { //if there is no space //no need to check if it's 0 times it will assign to 1 triggerSuggestionList(counter + 1); counter = 0; return; //set to rule action } else { //there is a space counter++; determineRuleActionRegion(str, num + 1); } } //end of determineactionRegion() So basically I find for the space and determine the region (number of words typed). However, I want it to change upon the user pressing space bar <space character>. How may I go around with the current code? Or better yet, how would one suggest me to do it the correct way? I'm figuring out on BreakIterator for this case... To add to that, I believe my algorithm won't work for multi sentences. How should I address this problem as well. -- The source of String str is acquired from textPane.getText(0, pos + 1);, the JTextPane. Thanks in advance. Do let me know if my question is still not specific enough.
