  • using checkbox yo update MySql table

    - by Martin
    Hi All I have been searching round the internet for days on this matter but I keep coming up against a brick wall. What I have is a table full of checkboxes inside an admin area acting as a monthly "to-do" list. It's essentially a worksheet of 30 or so things to do each month that must be checked off each month and notes added if applicable. I have managed to get the checkboxes to update via mysql and be shown somewhere as a list of ticks. I simply did this my setting the value to 1 and on submission it updates the sql table. I have to cover my bases here and also offer the option to un-tick items if they have been ticked b y mistake. But I cant figure out how this is done. Below is my checking code... any help on this matter would be great. <?php $currentTask = ''; echo "<tr class='tr'>"; while ($seolistRow = mysql_fetch_array($seolistRes)) { $taskValue = $seolistRow["taskValue"]; $worksheetID = $seolistRow["worksheetID"]; $taskName = $seolistRow["taskName"]; $taskInfo = $seolistRow["taskInfo"]; if ($taskValue == 1) { $taskDone = "<input type='checkbox' value='1' class='checkbox' name='checkbox".$worksheetID."' id=checkbox'".$worksheetID."' checked='checked' /><div class='taskinfo'>".$taskInfo."</div>"; } else { $taskDone = "<input type='checkbox' value='0' class='checkbox' name='checkbox".$worksheetID."' id='checkbox".$worksheetID."' />"; } if ($currentTask != $taskName) { echo "</tr>"; echo "<tr class='tr'>"; echo "<td class='task'>".$taskName."</td>"; } echo "<td class='tick'>".$taskDone."</td>"; $currentTask = $taskName; } echo "</tr>"; ?>

  • Problem to connect to MySQL server (error #2002) in PHP

    - by Martin Sikora
    Hello, I installed ZWAMP 1.0.7 (on Windows 7), but I'm having a weird problem. I can't connect to my MySQL server from any PHP script. If I try to use MySQL command line everything works fine but PHPMyAdmin retruns error #2002. I'm not sure whether it's important or not but MySQL server is not able to create socket file. I don't know what's the problem but I think everything is configured in my.cnf properly. Do you have any ideas?

  • Locating memory leak in Apache httpd process, PHP/Doctrine-based application

    - by Sam
    I have a PHP application using these components: Apache 2.2.3-31 on Centos 5.4 PHP 5.2.10 Xdebug 2.0.5 with Remote Debugging enabled APC 3.0.19 Doctrine ORM for PHP 1.2.1 using Query Caching and Results Caching via APC MySQL 5.0.77 using Query Caching I've noticed that when I start up Apache, I eventually end up 10 child processes. As time goes on, each process will grow in memory until each one approaches 10% of available memory, which begins to slow the server to a crawl since together they grow to take up 100% of memory. Here is a snapshot of my top output: PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 1471 apache 16 0 626m 201m 18m S 0.0 10.2 1:11.02 httpd 1470 apache 16 0 622m 198m 18m S 0.0 10.1 1:14.49 httpd 1469 apache 16 0 619m 197m 18m S 0.0 10.0 1:11.98 httpd 1462 apache 18 0 622m 197m 18m S 0.0 10.0 1:11.27 httpd 1460 apache 15 0 622m 195m 18m S 0.0 10.0 1:12.73 httpd 1459 apache 16 0 618m 191m 18m S 0.0 9.7 1:13.00 httpd 1461 apache 18 0 616m 190m 18m S 0.0 9.7 1:14.09 httpd 1468 apache 18 0 613m 190m 18m S 0.0 9.7 1:12.67 httpd 7919 apache 18 0 116m 75m 15m S 0.0 3.8 0:19.86 httpd 9486 apache 16 0 97.7m 56m 14m S 0.0 2.9 0:13.51 httpd I have no long-running scripts (they all terminate eventually, the longest being maybe 2 minutes long), and I am working under the assumption that once each script terminates, the memory it uses gets deallocated. (Maybe someone can correct me on that). My hunch is that it could be APC, since it stores data between requests, but at the same time, it seems weird that it would store data inside the httpd process. How can I track down which part of my app is causing the memory leak? What tools can I use to see how the memory usage is growing inside the httpd process and what is contributing to it?

  • How to access generic property without knowing the closed generic type

    - by Martin Booka Weser
    I have a generic Type as follows public class TestGeneric<T> { public T Data { get; set; } public TestGeneric(T data) { this.Data = data; } } If i have now an object (which is coming from some external source) from which i know that it's type is of some closed TestGeneric<, but i don't know the TypeParameter T. Now I need to access the Data of my object. Problem is that i can't cast the object, since i don't know exactly to which closed TestGeneric. I use // thx to http://stackoverflow.com/questions/457676/c-reflection-check-if-a-class-is-derived-from-a-generic-class private static bool IsSubclassOfRawGeneric(Type rawGeneric, Type subclass) { while (subclass != typeof(object)) { var cur = subclass.IsGenericType ? subclass.GetGenericTypeDefinition() : subclass; if (rawGeneric == cur) { return true; } subclass = subclass.BaseType; } return false; } to make sure, my object is of the generic type. The code in question is as follows: public static void Main() { object myObject = new TestGeneric<string>("test"); // or from another source if (IsSubclassOfRawGeneric(typeof(TestGeneric<>), myObject.GetType())) { // the following gives an InvalidCastException // var data = ((TestGeneric<object>)myObject).Data; // if i try to access the property with reflection // i get an InvalidOperationException var dataProperty = typeof(TestGeneric<>).GetProperty("Data"); object data = dataProperty.GetValue(myObject, new object[] { }); } } I need the Data regardless of its type (well, if i could ask for its type using GetType() would be fine, but not necessary) since i just want to dump it in xml using ToString(). Any suggestions? Thanx.

  • Replicate UISegmentedControl with UIButtons - iPhone

    - by Sam
    Hi guys, I didnt like the style of UISegmentedControl, hence i tried to change the way it looked, but I couldnt attach images to its buttons. I just didnt change at all. Now i'm looking at how to replicate that function with 4 UIButtons. I've setup 4 UIButtons in interface builder, added different tag numbers to them. What i cannot accomplish is when a button is tapped, it should be "selected" and the other buttons should be Unselected. How can i connect all of them? And if there was a way to change the UISegmented control looks, i would need all this effort. thanks for the help guys this is for iPhone OS

  • How to check if IIS is in 32bit or 64bit mode

    - by Sam
    I'm trying to deploy a site to a 64bit OS. I'm deploying to IIS. The site was developed on a 32bit server. The site deployed correctly however it's trying to access a COM component and that is failing. I believe the error is occurring because the COM component is a 64bit version on the 64bit OS. And IIS is running in 32bit mode on the 64bit server. I'd like to confirm this but I can't seem to find a definitive way to check if IIS is in 32bit mode or 64bit mode. Would someone know the best way to check if IIS is in 64bit or 32bit mode?

  • A good design pattern for almost similar objects

    - by Sam
    Hello, I have two websites that have an almost identical database schema. the only difference is that some tables in one website have 1 or 2 extra fields that the other and vice versa. I wanted to the same Database Access layer classes to will manipulate both websites. What can be a good design pattern that can be used to handle that little difference. for example, I have a method createAccount(Account account) in my DAO class but the implementation will be slightly different between website A and website B. I know design patterns don't depend on the language but FYI i m working with Perl. Thanks

  • jQuery programmatically removing validation highlighting

    - by Sam Carleton
    The form has two check boxes (cbDeclined & cbIsOOfFac), two text fields and a drop down (txtHeight, txtWeight, ddlDevice). If either check box is checked, then the other controls are disabled and the rules for the other do no apply. Here are the current rules: $('form').validate({ highlight: function (element, errorClass) { $(element).addClass("invalidElem"); }, unhighlight: function (element, errorClass) { $(element).removeClass("invalidElem"); }, errorPlacement: function (error, element) { var parent = element.parent(); parent.append(error); }, errorElement: "div", errorClass: "errorMsg" }); function HeightWeightCtrlsEnabled() { return !cbDeclined.is(':checked') && !cbIsOOfFac.is(':checked'); } txtHeight.rules("add", { required: function (element) { return HeightWeightCtrlsEnabled(); }, maxlength: 3, min: 1, digits: true }); txtWeight.rules("add", { required: function (element) { return HeightWeightCtrlsEnabled(); }, maxlength: 4, min: 1, digits: true }); ddlDevice.rules("add", { required: function (element) { return HeightWeightCtrlsEnabled(); } }); function UpdateTextBoxes() { var disableCtrls = !HeightWeightCtrlsEnabled(); txtHeight.prop('disabled', disableCtrls); txtWeight.prop('disabled', disableCtrls); ddlDevice.prop('disabled', disableCtrls); if (disableCtrls) { txtHeight.val(''); txtWeight.val(''); ddlDevice.val(''); } } cbDeclined.click(function () { if (cbDeclined.is(':checked')) cbIsOOfFac.attr('checked', false); UpdateTextBoxes(); }); cbIsOOfFac.click(function () { if (cbIsOOfFac.is(':checked')) cbDeclined.attr('checked', false); UpdateTextBoxes(); }); The problem comes in when: The user enters something into txtWeight, clicks the submit to get both ddlDevice & txtHeight to highlight because they are required, then... The user clicks on either cbDeclined & cbIsOOfFac. The highlight is NOT going away. I am trying to figure out how to get the highlighting around the height and drop down to go away. I tried to create a fully working jsFiddler, but I cannot get anything to work, though everything looks correct. here is the link (I cannot post links, so I expanded it a bit) jsfiddle dot net/scarleton/9hDZQ/12/ If you remove the last /12/, you will see my first version that is a cut/paste from the real thing. Per a suggestion I tried adding $('form').valid(); a number of places. When I added it to the end of the UpdateTextBoxes() function, they started out highlighted, not what I want. When I added it after the click() event of either of the radio button, the text would go away, but the actual controls stayed highlighted. It looks like the function on the required property of the rule is not fully working, maybe. What is really interesting is this: When I enter a height, click , then weight and device are highlighted and have the error message under them. When I click on one of the radio buttons, the text goes away, but the highlight does not. But... The height is NOT highlighted, it stays normal.

  • Linq2sql code generator misbehaving

    - by Martin
    Sometime the linq2sql just makes its mind up about things. I've been pulling my hair for the past hours trying to work out what I'm doing differently from all the other times when I don't get ForeignKeyReferenceAlreadyHasValueException. Turns out that if (this._Activity.HasLoadedOrAssignedValue) { throw new System.Data.Linq.ForeignKeyReferenceAlreadyHasValueException(); } is present on my primary key in this particular table, and in no other. No matter what I do with the association, I've even tried deleting and dragging the thing back to the designer, it's still there and I'm sure it's not supposed to be. I know why, of course, but I don't know why, so to speak. A while back the association went the other way. Whereas I've left that era behind me, the code generator seems to exhibit phantom pains. The same phenomenon, is responsible for me having to change the namespace in the designer.cs everytime I make changes in the designer. I made the mistake of renaming my namespace and the code generator just doesn't get it. Somebody please help this poor boy out.

  • Should I have different models and views for no user data than for some user data?

    - by Sam Holder
    I'm just starting to learn asp.net mvc and I'm not sure what the right thing to do is. I have a user and a user has a collection of (0 or more) reminders. I have a controller for the user which gets the reminders for the currently logged in user from a reminder service. It populates a model which holds some information about the user and the collection of reminders. My question is should I have 2 different views, one for when there are no reminders and one for when there are some reminders? Or should I have 1 view which checks the number of reminders and displays different things? Having one view seems wrong as then I end up with code in my view which says if (Model.Reminders.Count==0){//do something} else {do something else}, and having logic in the view feels wrong. But if I want to have 2 different views then I'd like to have some code like this in my controller: [Authorize] public ActionResult Index() { MembershipUser currentUser = m_membershipService.GetUser(); IList<Reminder> reminders = m_reminderRepository.GetReminders(currentUser); if (reminders.Count == 0) { var model = new EmptyReminderModel { Email = currentUser.Email, UserName = currentUser.UserName }; return View(model); } else { var model = new ReminderModel { Email = currentUser.Email, UserName = currentUser.UserName, Reminders = reminders }; return View(model); } but obviously this doesn't compile as the View can't take both different types. So if I'm going to do this should I return a specific named view from my controller, depending on the emptiness of the reminders, or should my Index() method redirect to other actions like so: [Authorize] public ActionResult Index() { MembershipUser currentUser = m_membershipService.GetUser(); IList<Reminder> reminders = m_reminderRepository.GetReminders(currentUser); if (reminders.Count == 0) { return RedirectToAction("ShowEmptyReminders"); } else { return RedirectToAction("ShowReminders"); } } which seems nicer but then I need to re-query the reminders for the current user in the ShowReminders action. Or should I be doing something else entirely?

  • Pitfalls and practical Use-Cases: Toplink, Hibernate, Eclipse Link, Ibatis ...

    - by Martin K.
    I worked a lot with Hibernate as my JPA implementation. In most cases it works fine! But I have also seen a lot of pitfalls: Remoting with persisted Objects is difficult, because Hibernate replaces the Java collections with its own collection implementation. So the every client must have the Hibernate .jar libraries. You have to take care on LazyLoading exceptions etc. One way to get around this problem is the use of webservices. Dirty checking is done against the Database without any lock. "Delayed SQL", causes that the data access isn't ACID compliant. (Lost data...) Implict Updates So we don't know if an object is modified or not (commit causes updates). Are there similar issues with Toplink, Eclipse Link and Ibatis? When should I use them? Have they a similar performance? Are there reasons to choose Eclipse Link/Toplink... over Hibernate?

  • Using Office 2010 web apps with ASP.NET

    - by Martin de Ruiter
    Would it be possible to use the Office 2010 web apps with an ASP.NET application? For example: - For each user of my ASP.NET application there is a folder with Word documents on my server - The ASP.NET application displays the available documents in a grid to the user - When clicking on one of the documents in the grid, the Word document is loaded in an IFrame which contains the Office 2010 web apps Word interface and editing of the document can take place - After editing, the document can be saved to the server, and the ASP.NET grid displays an updated status Would such a scenario be possible? And what do you need, e.g. Sharepoint, Office 2010 licenses?

  • wxPython, Threads, and PostEvent between modules

    - by Sam Starling
    I'm relatively new to wxPython (but not Python itself), so forgive me if I've missed something here. I'm writing a GUI application, which at a very basic level consists of "Start" and "Stop" buttons that start and stop a thread. This thread is an infinite loop, which only ends when the thread is stopped. The loop generates messages, which at the moment are just output using print. The GUI class and the infinite loop (using threading.Thread as a subclass) are held in separate files. What is the best way to get the thread to push an update to something like a TextCtrl in the GUI? I've been playing around with PostEvent and Queue, but without much luck. Here's some bare bones code, with portions removed to keep it concise: main_frame.py import wx from loop import Loop class MainFrame(wx.Frame): def __init__(self, parent, title): # Initialise and show GUI # Add two buttons, btnStart and btnStop # Bind the two buttons to the following two methods self.threads = [] def onStart(self): x = Loop() x.start() self.threads.append(x) def onStop(self): for t in self.threads: t.stop() loop.py class Loop(threading.Thread): def __init__(self): self._stop = threading.Event() def run(self): while not self._stop.isSet(): print datetime.date.today() def stop(self): self._stop.set() I did, at one point, have it working by having the classes in the same file by using wx.lib.newevent.NewEvent() along these lines. If anyone could point me in the right direction, that'd be much appreciated.

  • How to set AeDebug to get a minidump with the name of the process ?

    - by JC Martin
    I have to perform some post mortem debugging on a C++ project. Known way to perform is to set the cdb debugger as a minidump generator and to process the dumps collects afterwards. I read nearly the whole web and I didn't find a solution to produce a minidump with the name of the process that has crashed Is there a way to set AeDebug\Debugger registry variable in such a manner that cdb generates a dump file with the name of the process ? When I encapsulate the call to cdb.exe in a batch file, it starts well but stays blocked on the symbol searching. I must perform a Ctrl+C in order to stop the batch, then the minidump, with the correct process name, is created... but of course I can't set up such a thing in an unattended production environment... Has anybody done that before ?

    - by Martin
    I am quite new to intellij and i have loaded in a project that i wish to compile, everything seems to be going well, but when i compile it. I get the bundle cannot be found. java.util.MissingResourceException: Can't find bundle for base name openfire_i18n, locale en_US at java.util.ResourceBundle.throwMissingResourceException(ResourceBundle.java:1499) After doing some investigation, it appears i have to include the resources in the class path, is this correct? I have done Project Settings, Modules, Dependencies, and i added a "Jars or directories" There is a checkbox that says Export, i have tried clicking it and unclicking it :-) My resources i can see are in i8n\ResourceBundle I tried adding the i8n and it asked me for a category for selected files, i put classes RUN - but still same error.. so i tried adding the i8n/ResourceBundle directory RUN - still same error. I notice under my ResourceBundle directory there are C:\Dev\Java\openfire_src_3_7_1\openfire_src\src\i18n\openfire_i18n_en.properties but there is no specific en_US but i thought it supposed to fallback to EN ?? SO i think everything is ok. Can anyone help I am really stuck Thanks

  • oAuth provider with Django-piston

    - by Martin Eve
    Hi, I'm working with django-piston to attempt to create an API that supports oAuth. I started out using the tutorial at: http://blog.carduner.net/2010/01/26/django-piston-and-oauth/ I added a consumer to piston's admin interface with key and secret both set to "abcd" for test purposes. The urls are successfully wired-up and the oAuth provider is called. However, running my get request token tests with tripit (python get_request_token.py "http://127.0.0.1:8000/api" abcd abcd), I receive the following error: Invalid signature. Expected signature base string: GET&http%3A%2F%2F127.0.0.1%3A8000%2Fapi%2Foauth%2Frequest_token%2F&oauth_consumer_key%3Dabcd%26oauth_nonce%3D0c0bdded5b1afb8eddf94f7ccc672658%26oauth_signature_method%3DHMAC-SHA1%26oauth_timestamp%3D1275135410%26oauth_version%3D1.0 The problem seems to lie inside the _check_signature method of Piston's oauth.py, where valid_sig = signature_method.check_signature(oauth_request, consumer, token, signature) is returning false. I can't, however, work out how to get the signature validated. Any ideas?

  • Convert an array of bytes into one decimal number as a string

    - by Martin Kirsche
    I'm trying to write function that converts an arbitrary large array of bytes (larger than 64-bit) into a decimal number represented as string in c# and I simply can't figure out how to do it. For example the following code ... Console.WriteLine(ConvertToString( new byte[] { 0x11, 0x22, 0x33, 0x44, 0x55, 0x66, 0x77, 0x88, 0x99, 0xAA, 0xBB, 0xCC, 0xDD, 0xEE, 0xFF, 0x00 })); .. should print out 22774453838368691933757882222884355840 I don't want to just use an extra library like biginteger for that, because I want it to be simple and like to understand how it works.

  • Can I build this XPath query dynamically in XSLT?

    - by Martin Doms
    I have a document that looks something like <root> <element> <subelement1 /> <subelement2 /> </element> <element> <subelement2 /> <subelement1 /> </element> </root> In my XSLT sheet in the context of /element[2]/[someNode] I want to get a number that represents the distance of /element[1]/[someNode] (ie, the number of preceding siblings of /element1/[someNode]). For example, in the context of /element[2]/subelement1 I'd like to have some way to get the number 2, the distance from /element[1] to /element[1]/subelement2. I only ever need the distance of the given node name from the first instance of . Intuitively I thought I could construct this like <xsl:variable name="nodename" select="name()" /> <xsl:value-of select="/element[1]/$nodename/preceding-sibling::*" /> but unfortunately this sheet doesn't compile. Is what I'm trying to achieve possible in XSLT?

  • How to stop nant exec task putting ( ) around command line

    - by Sam
    I have looked through the nant documentation and sourceforge faq and can't find the answer to this question. The exec task in nant puts ( ) around the command line parameters it generates, so for example this task below would generate: mallow ( -1 ) <exec program="${build.tools.wix}\mallow.exe" workingdir="${build.out.xxx}"> <arg value="-1" /> </exec> The other open source tool I'm using - mallow - cannot handle this. Does anyone know of a way to stop nant putting the ( ) around the arguments? Thanks.

  • ruby, rails, railscasts example gone bad

    If you saw the railscasts on nested forms this is the helper method to create links dynamically. However, after I upgraded to ruby 1.9.2 and rails 3 this doesn't work and I have now idea why. def link_to_add_fields(name, f, association) new_object = f.object.class.reflect_on_association(association).klass.new fields = f.fields_for(association, new_object, :child_index => "new_#{association}") do |builder| render(association.to_s.singularize + "_fields", :f => builder) end link_to_function(name, h("add_fields(this, \"#{association}\", \"#{escape_javascript(fields)}\")")) end here is the javascript function add_fields(link, association, content) { var new_id = new Date().getTime(); var regexp = new RegExp("new_" + association, "g") $(link).up().insert({ before: content.replace(regexp, new_id) }); }
