  • Only variables can be passed by reference

    - by zaf
    I had the bright idea of using a custom error handler which led me down a rabbit hole. Following code gives (with and without custom error handler): Fatal error: Only variables can be passed by reference function foo(){ $b=array_pop(array("a","b","c")); return $b; } print_r(foo()); Following code gives (only with a custom error handler): (2048) Only variables should be passed by reference function foo(){ $a=explode( '/' , 'a/b/c'); $c=array_pop(array_slice($a,-2,1)); return $c; } print_r(foo()); The second one worries me since I have a lot of 'compact' code. So, I either ditch the bright idea of using a custom error handler (to improve my logging module) or expand all my code. Anyone with better ideas? Also, WTF?

  • New to asp.net. Need help debugging this email form.

    - by Roeland
    Hey guys, First of all, I am a php developer and most of .net is alien to me which is why I am posting here! I just migrated over a site from one set of webhosting to another. The whole site is written in .net. None of the site is database driven so most of it works, except for the contact form. The output on the site simple states there was an error with "There has been an error - please try to submit the contact form again, if you continue to experience problems, please notify our webmaster." This is just a simple message it pops out of it gets to the "catch" part of the email function. I went into web.config and changed the parameters: <emailaddresses> <add name="System" value="[email protected]"/> <add name="Contact" value="[email protected]"/> <add name="Info" value="[email protected]"/> </emailaddresses> <general> <add name="WebSiteDomain" value="hoyespharmacy.com"/> </general> Then the .cs file for contact contains the mail function EmailFormData(): private void EmailFormData() { try { StringBuilder body = new StringBuilder(); body.Append("Name" + ": " + txtName.Text + "\n\r"); body.Append("Phone" + ": " + txtPhone.Text + "\n\r"); body.Append("Email" + ": " + txtEmail.Text + "\n\r"); body.Append("Fax" + ": " + txtEmail.Text + "\n\r"); body.Append("Subject" + ": " + ddlSubject.SelectedValue + "\n\r"); body.Append("Message" + ": " + txtMessage.Text); MailMessage mail = new MailMessage(); mail.IsBodyHtml = false; mail.To.Add(new MailAddress(Settings.GetEmailAddress("System"))); mail.Subject = "Contact Us Form Submission"; mail.From = new MailAddress(Settings.GetEmailAddress("System"), Settings.WebSiteDomain); mail.Body = body.ToString(); SmtpClient smtpcl = new SmtpClient(); smtpcl.Send(mail); } catch { Utilities.RedirectPermanently(Request.Url.AbsolutePath + "?messageSent=false"); } } How do I see what the actual error is. I figure I can do something with the "catch" part of the function.. Any pointers? Thanks!

  • AutoHotkey ControlSend problem on one machine

    - by Illotus
    I have this AutoHotkey script that has a weird problem. It is used in 3 workstations, but in one the ControlSend doesn't seem to work as the hotkey doesn't work in program A. All three machines have Windows XP and are Pentium 4 level machines with mostly same software, the script is in exe form. I've tried a lot of different ways to send the hotkey to Program A, but nothing seems to work. The idea of the script is simply to catch a hotkey and click in another window in addition to its normal function. The normal function just doesn't work. Any ideas what could be the root of the problem and where I should look for it? #IfWinActive, Program A ^H:: IfWinActive, Program A { ControlFocus, MDIClient1, Program A, , , ControlSend, , ^H, Program A, , , ControlClick, X46 Y135, Program B, , LEFT , 1 return }

  • table cell background color change problem

    - by Mellon
    I work on another guy's code, and I try to change the table cell background color when mouse over the cell, and change back to the original background color when mouse leave. I use the following code: var bgcolor=$(".cell-el").css("background-color") $(".cell-el").hover( function(){ $(this).css("background-color", "#3c3c36")}, //mouse enter, bg-color change function(){ $(this).css("background-color", bgcolor) // mouse leave, bg-color change back }) Things are working fine, EXCEPT that when mouse first time enter the cell, the cell background color is not changed to "#3c3c36", but when mouse leave the cell after first entering and enter in the cell again, the cell's background color changed to "#3c3c36". That's the cell color never change for mouse first enter, after that, everything is working great. What's could be the cause of this problem?

  • Adding a link to image breaks jquery slider, help please!

    - by lewisqic
    Hi All, I am working on a site for a friend and trying to add a link to each image in a slide show. The slide show uses jquery and a script called easySlider1.7.js. Everything works just fine if the images are left alone, but when I try and wrap the images with a link, the slides no longer progress as they should. Here is the live website that is displaying the problem... http://www.splits59.com/ Here is the html code for each of the slide images... <div class="covercontent2box"> <div class="covercontent2"> <div id="slideshow"> <a href="/ashton-jacket-p-107.html"><img src="img/homepagesummer2010_2.2-cut.jpg" class="active" /></a> <a href="/carly-coverup-p-106.html"><img src="img/homepagesummer2010_3.2-cut.jpg" /></a> <a href="/shop-online-bottoms-c-15_14.html"><img src="img/homepagesummer2010_1.2-cut.jpg" /></a> </div> </div> </div> And here is the jquery code on the page that controls the slider... <script type="text/javascript"> function slideSwitch() { var $active = $('#slideshow IMG.active'); if ( $active.length == 0 ) $active = $('#slideshow IMG:last'); // use this to pull the images in the order they appear in the markup var $next = $active.next().length ? $active.next() : $('#slideshow IMG:first'); $active.addClass('last-active'); $next.css({opacity: 0.0}) .addClass('active') .animate({opacity: 1.0}, 1000, function() { $active.removeClass('active last-active'); }); } $(function() { setInterval( "slideSwitch()", 4500 ); }); </script> Does anyone have any idea why adding a link tag to the images breaks the slider? Any help or direction provided would be appreciated. Thanks, Devin

  • rhino embedding

    - by neheh
    Anyone understands the rhino javascript Contexts? I cannot find any useful documentation about it. My main problem is the Context.exit() (really should be cx.exit()) which from what I understand exits the context associated with the current thread? Does that mean I need to keep track of what which thread does? main thread: Context cx; cx.evaluateReader( ... ) // load some function start thread 2 thread 2: Object o= scope.get("methodname", scope); ((Function)o).call( ... ) I do not plan on doing multithreading but what if the different setups comes from different threads?

  • jquery to check when a someone starts typing in to a field

    - by Drew
    $('a#next').click(function() { var tags = $('input[name=tags]'); if(tags.val()==''){ tags.addClass('hightlight'); return false; }else{ tags.removeClass('hightlight'); $('#formcont').fadeIn('slow'); $('#next').hide('slow'); return false; } }); I would like the above code to fire the fadeIn as soon as somebody starts typing into the tags input. Can somebody tell me the correct way to do this or point me in the right direction? Thanks in advance EDIT here is the code to do it: $('input#tags').keypress(function() { $('#formcont').fadeIn('slow'); $('#next').hide('slow'); }); The only problem I've found is that my cursor no longer shows up in the text box. What am I doing wrong?

  • 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?

  • Multiprocessing Bomb

    - by iKarampa
    I was working the following example from Doug Hellmann tutorial on multiprocessing: import multiprocessing def worker(): """worker function""" print 'Worker' return if __name__ == '__main__': jobs = [] for i in range(5): p = multiprocessing.Process(target=worker) jobs.append(p) p.start() When I tried to run it outside the if statement: import multiprocessing def worker(): """worker function""" print 'Worker' jobs = [] for i in range(5): p = multiprocessing.Process(target=worker) jobs.append(p) p.start() It started spawning processes non-stop, without any way of to terminating it. Why would that happen? Why it did not generate 5 processes and exit? Why do I need the if statement?

  • I have a bunch of images being shown on click via JQuery - any easy way to animate this?

    - by Cenk
    This is the (quite simple) JS code I'm using: $(document).ready(function() { $(".button-list .next").click(function() { project = $(this).parents().filter(".projektweb").eq(0); currentimg = project.find(".images-list li.current"); nextimg = currentimg.next(); firstimg = project.find(".images-list li:first"); currentimg.removeClass("current"); if (nextimg.is("li")) nextimg.addClass("current"); else firstimg.addClass("current"); return false; }); $(".button-list .prev").click(function() { project = $(this).parents().filter(".projektweb").eq(0); currentimg = project.find(".images-list li.current"); previmg = currentimg.prev(); lastimg = project.find(".images-list li:last"); currentimg.removeClass("current"); if (previmg.is("li")) previmg.addClass("current"); else lastimg.addClass("current"); return false; }); }); And this is how the HTML code for the image list looks like: <ul class="images-list"> <li class="current"><img src="img/1.jpg" alt="" /></li> <li><img src="img/1b.jpg" alt="" /></li> </ul> <ul class="button-list"> <li><a class="button prev" href="#">?</a></li> <li><a class="button next" href="#">?</a></li></ul> The CSS: .images-list { height: 460px; list-style-type:none; float:left; width: 460px; overflow:hidden; position:relative; } .images-list img { height: 460px; width: 460px; display:block; } .images-list li { display:none; } .images-list li.current { display:block; } What I'd like to do is animate the images as they come and go - right now they just appear, which is OK but a bit more eye-candy would be nice. Can anyone help me out here? It it even possible to do it this way? Thanks!!

  • Randomized experiments in R

    - by gd047
    Here is a simple randomized experiment. In the following code I calculate the p-value under the null hypothesis that two different fertilizers applied to tomato plants have no effect in plants yields. The first random sample (x) comes from plants where a standard fertilizer has been used, while an "improved" one has been used in the plants where the second sample (y) comes from. x <- c(11.4,25.3,29.9,16.5,21.1) y <- c(23.7,26.6,28.5,14.2,17.9,24.3) total <- c(x,y) first <- combn(total,length(x)) second <- apply(first,2,function(x) total[!total %in% x]) dif.treat <- apply(second,2,mean) - apply(first,2,mean) # the first element of dif.treat is the one that I'm interested in (p.value <- length(dif.treat[dif.treat >= dif.treat[1]]) / length(dif.treat)) Do you know of any R function that performs tests like this one?

  • Linking to a C library compiled as C++

    - by Jacob
    I'm in linker paradise now. I have a C library which only compiles in Visual C++ (it probably works in gcc) if: I compile it as C++ code Define __cplusplus which results in all the declarations being enclosed in extern "C" { } So, by doing this I have a static library called, say, bsbs.lib Now, I have a C++ project called Tester which would like to call function barbar in declared in bsbs.h. All goes fine, until I try to link to bsbs.lib where I get the all-too-familiar: Tester.obj : error LNK2001: unresolved external symbol _foofoo And it always seems to be foofoo which cannot be resolved regardless of which function I call in Tester (barbar or anything else).

  • MySQL triggers cannot update rows in same table the trigger is assigned to. Suggested workaround?

    - by Cory House
    MySQL doesn't currently support updating rows in the same table the trigger is assigned to since the call could become recursive. Does anyone have suggestions on a good workaround/alternative? Right now my plan is to call a stored procedure that performs the logic I really wanted in a trigger, but I'd love to hear how others have gotten around this limitation. Edit: A little more background as requested. I have a table that stores product attribute assignments. When a new parent product record is inserted, I'd like the trigger to perform a corresponding insert in the same table for each child record. This denormalization is necessary for performance. MySQL doesn't support this and throws: Can't update table 'mytable' in stored function/trigger because it is already used by statement which invoked this stored function/trigger. A long discussion on the issue on the MySQL forums basically lead to: Use a stored proc, which is what I went with for now. Thanks in advance!

  • Placement of a call to the parent method

    - by Alejandro
    I have a class that has a method. That class has a child class that overrides that method. The child's method has to call the parent's method. In all OO that I've seen or written calls to the parent's version of the same method were on the first line of the method. On a project that I am working on circumstances call for placing that method call at the end of a method. Should I be worried? Is that a code smell? Is this code inherently bad? class Parent { function work() { // stuff } } class Child { function work() { // do thing 1 // do thing 2 parent::work(); // is this a bad practice? // should I call the parent's work() method before // I do anything in this method? } }

    - by HerbalMart
    I am using the code as below of this post: First i will an fill array variable with the correct values for the controller action. Using the code below i think it should be very straigtforward by just adding the following line to the javascript: data["__RequestVerificationToken"] = $('[name=__RequestVerificationToken]').val(); The <%= Html.AntiForgeryToken() %> is at his right place and the action has a [ValidateAntiForgeryToken] But my controller action keeps saying: "Invalid forgery token" What am i doing wrong here? Code data["fiscalyear"] = fiscalyear; data["subgeography"] = $(list).parent().find('input[name=subGeography]').val(); data["territories"] = new Array(); $(items).each(function() { data["territories"].push($(this).find('input[name=territory]').val()); }); if (url != null) { $.ajax( { dataType: 'JSON', contentType: 'application/json; charset=utf-8', url: url, type: 'POST', context: document.body, data: JSON.stringify(data), success: function() { refresh(); } }); }

  • Help! How to get the event handler with IE Dom interfaces?

    - by usfree74
    Hey Gurus, I am working to use IE Dom interface to automate IE page access. I am trying to get all event handlers defined in a page. I am using IHTMLElement object now for this purpose. If the html page defines "onclick=xxx", element.onclick returns the click handler. However, if an event handler is defined in javascript, element.onclick simply returns NULL. What's the right way to get the event handler then? Thanks, xin Below is an example that uses javascript to define event handler. $(document).ready(function(){ $("a").click(function(event){ $(this).hide("slow"); alert("Thanks for visiting!"); window.location="http://cnn.com"; }); }); jQuery
