  • Form Validation using Java inside PHP

    - by Mikey1980
    I have a simple problem but no matter what I try I can't see to get it to work. I have a form on a php page and I need to validate the qty value on my form so that it doesn't exceed $qty (value pulled from mySQL) and is not less than zero. Sounds easy--hmm wish it were..lol! I had it checking if the value was numeric and in my attempts to make this work I even broke that--not a good morning..lol! Here's a snip of my Java Fn: <script type='text/javascript'> function checkQty(elem){ var numericExpression = /^[0-9]+$/; if(elem.value.match(numericExpression)){ return true; }else{ alert("Quantity for RMA must be greater than zero and less than original order!"); elem.focus(); return false; } } </script> The function is called from the submit button, onClick: <input type="submit" name="submit" onclick="checkQty(document.getElementById('qty')";"> I've tried: var numericExpression = /^[0-9]+$/; if(elem.value.match(numericExpression) || elem.value < 0 || elem.value > <? int($qty) ?>){ No dice....HELP!?!

  • TinyMce imagemanager won't generate image path when used with an iframe

    - by Tom
    I have successfully setup tinymce to work on a page within an iframe. Everything works perfectly. However, when you use imagemanager to pick an image to be inserted or replaced in the editor it will not copy the path(and filename) of the image to the "Image URL" input in the "Insert/edit image" box. The box will either remain empty or keep the address of the previous image. The behaviour is the same with the filemanager plugin. tinyMCE.init( { mode : "none", editor_selector : "mceEditor", theme : "advanced", plugins : "filemanager,imagemanager,autoresize,safari,pagebreak,style,layer,table,save,advhr,advimage,advlink,emotions,iespell,insertdatetime,preview,media,searchreplace,print,contextmenu,paste,directionality,fullscreen,noneditable,visualchars,nonbreaking,xhtmlxtras,template,inlinepopups,spellchecker", theme_advanced_buttons1 : "insertfile,insertimage,advimage,imagemanager,bold,italic,underline,|,justifyleft,justifycenter,justifyright,justifyfull,nonbreaking,cut,copy,paste,pastetext,pasteword,|,search,replace,|,bullist,numlist", theme_advanced_buttons2 : "blockquote,|,link,unlink,anchor,image,cleanup,help,code,|,insertdate,inserttime,|,forecolor,backcolor,|,charmap,iespell,media,advhr", theme_advanced_layout_manager : "SimpleLayout", theme_advanced_buttons3 : "tablecontrols,|,hr,removeformat,visualaid,|,sub,sup,strikethrough", theme_advanced_buttons4 : "styleselect,formatselect,fontselect,fontsizeselect,|,undo,redo,|,spellchecker", theme_advanced_toolbar_location : "external", theme_advanced_toolbar_align : "left", theme_advanced_statusbar_location : "bottom", relative_urls : true, document_base_url : "http://devtom.ecitb.org.uk/", auto_resize : true, content_css : "/custom/css/style.css", extended_valid_elements : "iframe[height|width|src|frameborder|scrolling]", }); /* The following code comes from- http://tinymce.moxiecode.com/punbb/viewtopic.php?id=12966 Without it the editor only loads 10% of the time.

  • Javascript Object.Watch for all browsers?

    - by SeanW
    Hey all, I was looking for an easy way to monitor an object or variable for changes, and I found Object.Watch that's supported in Mozilla browsers, but not IE. So I started searching around to see if anyone had written some sort of equivalent. About the only thing I've found has been a jQuery plugin (http://plugins.jquery.com/files/jquery-watch.js.txt), but I'm not sure if that's the best way to go. I certainly use jQuery in most of my projects, so I'm not worried about the jQuery aspect... Anyway, the question: can someone show me a working example of that jQuery plugin? I'm having problems making it work... Or, does anyone know of any better alternatives that would work cross browser? Thanks! Update after answers: Thanks everyone for the responses! I tried out the code posted here: http://webreflection.blogspot.com/2009/01/internet-explorer-object-watch.html But I couldn't seem to make it work with IE. The code below works fine in FireFox, but does nothing in IE. In Firefox, each time watcher.status is changed, the document.write in watcher.watch is called and you can see the output on the page. In IE, that doesn't happen, but I can see that watcher.status is updating the value, because the last document.write shows the correct value (in both IE and FF). But, if the callback function isn't called, then that's kind of pointless... :) Am I missing something? var options = {'status': 'no status'}, watcher = createWatcher(options); watcher.watch("status", function(prop, oldValue, newValue) { document.write("old: " + oldValue + ", new: " + newValue + "<br>"); return newValue; }); watcher.status = 'asdf'; watcher.status = '1234'; document.write(watcher.status + "<br>");

  • Is this the right way to organize my database tables?

    - by Moss
    So I'm making a website that allows users to build contact lists. So their are users, the users have lists, and the lists have contacts. It seems to me that I need 3 tables for this but I just want to make sure. There would be a User table of course, and then a "List of Lists" table that has the username, and listname, as primary key along with whatever other info we want to attach to the lists as a whole. Finally, for lack of a better word, the List table which would again have the username/listname p.k., then the contact ID and notes and such that the user attaches to that contact on that specific list. I hope that is a clear explanation. For some reason I feel unsure about this arrangement. For one thing if the website becomes popular the List table could swell to billions of rows. And it also feels a little weird that everybody's list info is all jumbled up in the same table. I suppose I could create separate tables for each user and even for each list but that seems like a bad idea for other reasons. My db explanation assumes I can use foreign keys on my tables which at the moment isn't actually an option. If I can't get InnoDB tables enabled I will probably use ID's for the lists instead of depending on a compound key. Maybe I should do this anyway?

  • Custom rowsetClass does not return values

    - by Wesley
    Hi, I'm quite new to Zend and the database classes from it. I'm having problems mapping a Zend_Db_Table_Row_Abstract to my rows. The problem is that whenever I try to map it to a class (Job) that extends the Zend_Db_Table_Row_Abstract class, the database data is not receivable anymore. I'm not getting any errors, trying to get data simply returns null. Here is my code so far: Jobs: class Jobs extends Zend_Db_Table_Abstract { protected $_name = 'jobs'; protected $_rowsetClass = "Job"; public function getActiveJobs() { $select = $this->select()->where('jobs.jobDateOpen < UNIX_TIMESTAMP()')->limit(15,0); $rows = $this->fetchAll($select); return $rows; } } Job: class Job extends Zend_Db_Table_Row_Abstract { public function getCompanyName() { //Gets the companyName } } Controller: $oJobs = new Jobs(); $aActiveJobs = $oJobs->getActiveJobs(); foreach ($aActiveJobs as $value) { var_dump($value->jobTitle); } When I remove the "protected $_rowsetClass = "Job";" line, so that the table row is not mapped to my own class, I get all the jobTitles perfectly. What am I doing wrong here? Thanks in advance, Wesley

  • Iframe in Tab Madness!

    - by 404error
    I've searched all over and have found possible solutions but they don't quite work how i need them to. I am really new to jQuery but I'm trying :-) I have an iframe that sits in a Tab ( Tabs powered by jQuery) In the third tab sits an iframe that holds a slideshow My problem: When I click on the third tab which houses the iframe all the controls appear, the carousel seems to be working, but ...no pictures!!! Firefox helped me find what fixes the problem, now i just need to find a way to do fix it. In Firefox when i right click on the iframe and go to This frame - Reload Frame VOILA! Pictures are back! Question: Is it possible with jQuery to tell when the third tab is selected and to refresh a div which contains the iframe when that third tab is selected? Tab Code: <script type="text/javascript" charset="utf-8"> $(function () { var tabContainers = $('div.tabs > div'); tabContainers.hide().filter(':first').show(); $('div.tabs ul.tabNavigation a').click(function () { tabContainers.hide(); tabContainers.filter(this.hash).show(); $('div.tabs ul.tabNavigation a').removeClass('selected'); $(this).addClass('selected'); return false; }).filter(':first').click(); }); </script> Test page can be found here: http://artitechture.com/blah/tabs.html Any help would be appreciated...I want to learn!

  • php POST response

    - by amit
    I am making a POST to another php file that I want to render in the browser. so clearly, using jquery POST wont work, since it works through AJAX. echo '<div class="showcase_URL"><a class="purl" name="'.$row->num.'" href="#">PROJECT URL</a></div>'; what I have till now in javascript is: $(".showcase_URL a").click(function() { //alert($(this).attr("name")); var number = $(this).attr("name"); $.post( "app-display.php", {app: number}, function(data){ top.location.href = 'app-display.php'; }); }); what I have in app-display.php: $query = 'SELECT num, title, thumb_url, url, type, cat, dated, details FROM app WHERE `num` = "$_POST[app]"'; but it is currently giving me a page without the contents of app-display.php. all the other fragments of the page are loading: header, footer etc. the PHP Response (in Firebug) I am getting is the normal html of the page. how should i do it?

  • How to access C arrays from assembler for Windows x64?

    - by 0xdword32
    I've written an assembler function to speed up a few things for image processing (images are created with CreateDIBSection). For Win32 the assembler code works without problems, but for Win64 I get a crash as soon as I try to access my array data. I put the relevant info in a struct and my assembler function gets a pointer to this struct. The struct pointer is put into ebx/rbx and with indexing I read the data from the struct. Any idea what I am doing wrong? I use nasm together with Visual Studio 2008 and for Win64 I set "default rel". C++ code: struct myData { tUInt32 ulParam1; void* pData; }; CallMyAssemblerFunction(&myData); Assembler Code: Win32: ... push ebp; mov ebp,esp mov ebx, [ebp + 8]; pointer to our struct mov eax, [ebx]; ulParam1 mov esi, [ebx + 4]; pData, 4 byte pointer movd xmm0, [esi]; ... Win64: ... mov rbx, rcx; pointer to our struct mov eax, [rbx]; ulParam1 mov rsi, [rbx + 4]; pData, 8 byte pointer movd xmm0, [rsi]; CRASH! ...

  • firefox and javascript redirection

    - by Joe
    Hello there, I currently have a issue with firefox, where all other browser behave in the right way - even IE6! What I want to do is redirection to a subpage but leaving a history entry. There are 2 methods of rewriting the url as far as I know: window.location = "some.url"; - redirect to some.url with history entry window.location.replace("some.url"); - redirect without history entry So I have to use the first one and tested in the firebug console everthing works fine. Now there is the kind of strange part of this question: the same statement, that worked fine in the console doesn't in some jQuery callback handler: jQuery("#selector").bind("submit", function() { $.getJSON("some_cool_json", function(response) { var redirect_path = response.path; window.location = redirect_path; }); return false; }); where response_path is set correctly, I checked it! Even the redirection is working correctly, but there is no history entry created. Any ideas on that one? Would be great! ;) Cheers Joe

  • Temporary non-const istream reference in constructor (C++)

    - by Christopher Bruns
    It seems that a constructor that takes a non-const reference to an istream cannot be constructed with a temporary value in C++. #include <iostream> #include <sstream> using namespace std; class Bar { public: explicit Bar(std::istream& is) {} }; int main() { istringstream stream1("bar1"); Bar bar1(stream1); // OK on all platforms // compile error on linux, Mac gcc; OK on Windows MSVC Bar bar2(istringstream("bar2")); return 0; } This compiles fine with MSVC, but not with gcc. Using gcc I get a compile error: g++ test.cpp -o test test.cpp: In function ‘int main()’: test.cpp:18: error: no matching function for call to ‘Bar::Bar(std::istringstream)’ test.cpp:9: note: candidates are: Bar::Bar(std::istream&) test.cpp:7: note: Bar::Bar(const Bar&) Is there something philosophically wrong with the second way (bar2) of constructing a Bar object? It looks nicer to me, and does not require that stream1 variable that is only needed for a moment.

  • iPhone - Memory Management - Using Leaks tool and getting some bizarre readings.

    - by Robert
    Hey all, putting the finishing touches on a project of mine so I figured I would run through it and see if and where I had any memory leaks. Found and fixed most of them but there are a couple of things regarding the memory leaks and object alloc that I am confused about. 1) There are 2 memory leaks that do not show me as responsible. There are 8 leaks attributed to AudioToolbox with the function being RegisterEmbeddedAudioCodecs(). This accounts for about 1.5 kb of leaks. The other one is detected immediately when the app begins. Core Graphics is responsible with the extra info being open_handle_to_dylib_path. For the audio leak I have looked over my audio code and to me it seems ok. self.musicPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:songFilePath] error:NULL]; [musicPlayer prepareToPlay]; [musicPlayer play] is called later on in a function. 2) Is it normal for there to be a spike in Object Allocation whenever a new view or controller is presented? My total memory usage is very, very low except for whenever I present a view controller. It spikes then immediately goes back down. I am guessing that this is just the phone handling all the information for switching or something. Blegh. Wall of text. Thanks in advance to anyone who helps! =)

  • how to create a changing variable for fsolve

    - by Shun Miyamoto
    i want fsolve to calculate the output for different uc each time (increasing uc by 0.001 each time). each output from fsolve should be sent to a simulink model seperatly. so i set a loop to do so, but i believe that at the currenty constellation (if it will work)will just calculate 1000 different values? is there a way to send out the values seperately? if not, how can i create a parameter uc. that goes from 0 to say 1000? i tried uc=0:0.001:1000, but again, the demension doen't seem to fit. how do i create a function that takes the next element of a vector/matrix each time the function is called? uc=0; for i=0:1000 x0=[1,1,1]; y=x0(1); u=x0(2); yc=x0(3); options=optimset('Display','off'); x= fsolve(@myfun,x0,options,uc,d,spacing_amplitude,spacing_width); end best regards

  • Qt - QWebView Problem

    - by user547057
    Hi, I have a PyQt gui script which consists of a QWebView widget. I'm trying to send a GET request, i.e go to a page, fill a form and hit click using the code at the bottom of this question. Since i'm dealing with the documentElement(a QWebElement) of the webview, I need to place all DOM actions in a separate function(which I have named fillForm) and connect the loadFinished() signal into the function. Without connecting the signal, the document will not have loaded and I won't be able to get the elements I want. I'm able to submit the form correctly and get the proper response from the webpage. The problem i'm having is that, the above leads to a sort of infinite loop. This is because the webpage gets reloaded each time a new page is loaded, so the form gets filled each and every single time without stopping. I'd like to know if there's some way of finding out whether the WebView's page has loaded fully, non-asynchronously or maybe pause execution of the script(without freezing the gui) until the whole document has loaded. I'm unable to come up with a satisfactory solution(my idea consisted of keeping a global variable to track clicks) to this problem. I would appreciate it if someone could help me out with a better way to tackle this. Thanks! Here's the code i'm using import sys from PyQt4.QtCore import * from PyQt4.QtGui import * from PyQt4.QtWebKit import * from PyQt4 import QtCore app = QApplication(sys.argv) web = QWebView() web.load(QUrl("http://mywebsite.com")) def fillForm(): doc = web.page().mainFrame().documentElement() searchform = doc.findFirst("input[type=text]") searchform.setAttribute("value", "hello") button = doc.findFirst("input[type=submit]") button.evaluateJavaScript("click()") QtCore.QObject.connect(web, QtCore.SIGNAL("loadFinished"), fillForm) web.show() sys.exit(app.exec_())

  • How to detect whether there is a specific member variable in class?

    - by Kirill V. Lyadvinsky
    For creating algorithm template function I need to know whether x or X (and y or Y) in class that is template argument. It may by useful when using my function for MFC CPoint class or GDI+ PointF class or some others. All of them use different x in them. My solution could be reduces to the following code: template<int> struct TT {typedef int type;}; template<class P> bool Check_x(P p, typename TT<sizeof(&P::x)>::type b = 0) { return true; } template<class P> bool Check_x(P p, typename TT<sizeof(&P::X)>::type b = 0) { return false; } struct P1 {int x; }; struct P2 {float X; }; // it also could be struct P3 {unknown_type X; }; int main() { P1 p1 = {1}; P2 p2 = {1}; Check_x(p1); // must return true Check_x(p2); // must return false return 0; } But it does not compile in Visual Studio, while compiling in the GNU C++. With Visual Studio I could use the following template: template<class P> bool Check_x(P p, typename TT<&P::x==&P::x>::type b = 0) { return true; } template<class P> bool Check_x(P p, typename TT<&P::X==&P::X>::type b = 0) { return false; } But it does not compile in GNU C++. Is there universal solution? UPD: Structures P1 and P2 here are only for example. There are could be any classes with unknown members.

  • Better way to call superclass method in ExtJS

    - by Rene Saarsoo
    All the ExtJS documentation and examples I have read suggest calling superclass methods like this: MyApp.MyPanel = Ext.extend(Ext.Panel, { initComponent: function() { // do something MyPanel specific here... MyApp.MyPanel.superclass.initComponent.call(this); } }); I have been using this pattern for quite some time and the main problem is, that when you rename your class then you also have to change all the calls to superclass methods. That's quite inconvenient, often I will forget and then I have to track down strange errors. But reading the source of Ext.extend() I discovered, that instead I could use the superclass() or super() methods that Ext.extend() adds to the prototype: MyApp.MyPanel = Ext.extend(Ext.Panel, { initComponent: function() { // do something MyPanel specific here... this.superclass().initComponent.call(this); } }); In this code renaming MyPanel to something else is simple - I just have to change the one line. But I have doubts... I haven't seen this documented anywhere and the old wisdom says, I shouldn't rely on undocumented behaviour. I didn't found a single use of these superclass() and supr() methods in ExtJS source code. Why create them when you aren't going to use them? Maybe these methods were used in some older version of ExtJS but are deprecated now? But it seems such a useful feature, why would you deprecate it? So, should I use these methods or not?

  • jquery - problem with executing annimation of two separate objects, one after another

    - by MoreThanChaos
    Hello I have problem to put together animations of two separate objects to second one start when first one ends. I tried to use callback but it seems that i make some syntax misteakes which crash jQuery or cause some unexpected behaviour. It seems that i'm stuck so I'd like to ask You for best way to put these animations together to act the way I want. in mouseenter 1st .pp grows, 2nd .tt fade in in mouseleave 1st .tt fade out, 2nd .pp shrink It's alsp relevant that animations doesn't pile up, i mean here animation called by one event doesnt wait until other animation in progress will end. In generall exactly what is below but yo be animated one after another, not simultanously. $('.pp').bind({ mouseenter: function() { $(this).animate({ width: $(this).children(".tt").outerWidth(), height: $(this).children(".tt").outerHeight() },{duration:1000,queue:false} ); $(this).children(".tt").animate({ opacity: 1.0 }, {duration:1000,queue:false}); }, mouseleave: function() { $(this).children(".tt").animate({ opacity: 0 }, {duration:1000,queue:false}); $(this).animate({ width: 17, height: 17 }, {duration:1000,queue:false}); } });

  • Increasing Regex Efficiency

    - by cam
    I have about 100k Outlook mail items that have about 500-600 chars per Body. I have a list of 580 keywords that must search through each body, then append the words at the bottom. I believe I've increased the efficiency of the majority of the function, but it still takes a lot of time. Even for 100 emails it takes about 4 seconds. I run two functions for each keyword list (290 keywords each list). public List<string> Keyword_Search(HtmlNode nSearch) { var wordFound = new List<string>(); foreach (string currWord in _keywordList) { bool isMatch = Regex.IsMatch(nSearch.InnerHtml, "\\b" + @currWord + "\\b", RegexOptions.IgnoreCase); if (isMatch) { wordFound.Add(currWord); } } return wordFound; } Is there anyway I can increase the efficiency of this function? The other thing that might be slowing it down is that I use HTML Agility Pack to navigate through some nodes and pull out the body (nSearch.InnerHtml). The _keywordList is a List item, and not an array.

  • should variable be released or not? iphone-sdk

    - by psebos
    Hi, In the following piece of code (from a book) data is an NSDictionary *data; defined in the header (no property). In the viewDidLoad of the controller the following occurs: - (void)viewDidLoad { [super viewDidLoad]; NSArray *keys = [NSArray arrayWithObjects:@"home", @"work", nil]; NSArray *homeDVDs = [NSArray arrayWithObjects:@"Thomas the Builder", nil]; NSArray *workDVDs = [NSArray arrayWithObjects:@"Intro to Blender", nil]; NSArray *values = [NSArray arrayWithObjects:homeDVDs, workDVDs, nil]; data = [[NSDictionary alloc] initWithObjects:values forKeys:keys]; } Since I am really new to objective-c can someone explain to me why I do not have to retain the variables keys,homeDVDs,workDVDs and values prior exiting the function? I would expect prior the data allocation something like: [keys retain]; [homeDVDs retain]; [workDVDs retain]; [values retain]; or not? Does InitWithObjects copies (recursively) all objects into a new table? Assuming we did not have the last line (data allocation) should we release all the NSArrays prior exiting the function (or we could safely assumed that all NSArrays will be autoreleased since there is no alloc for each one?) Thanks!!!!

  • How to Avoid PHP Object Nesting/Creation Limit?

    - by Will Shaver
    I've got a handmade ORM in PHP that seems to be bumping up against an object limit and causing php to crash. Here's a simple script that will cause crashes: <? class Bob { protected $parent; public function Bob($parent) { $this->parent = $parent; } public function __toString() { if($this->parent) return (string) "x " . $this->parent; return "top"; } } $bobs = array(); for($i = 1; $i < 40000; $i++) { $bobs[] = new Bob($bobs[$1 -1]); } ?> Even running this from the command line will cause issues. Some boxes take more than 40,000 objects. I've tried it on Linux/Appache (fail) but my app runs on IIS/FastCGI. On FastCGI this causes the famous "The FastCGI process exited unexpectedly" error. Obviously 20k objects is a bit high, but it crashes with far fewer objects if they have data and nested complexity. Fast CGI isn't the issue - I've tried running it from the command line. I've tried setting the memory to something really high - 6,000MB and to something really low - 24MB. If I set it low enough I'll get the "allocated memory size xxx bytes exhausted" error. I'm thinking that it has to do with the number of functions that are called - some kind of nesting prevention. I didn't think that my ORM's nesting was that complicated but perhaps it is. I've got some pretty clear cases where if I load just ONE more object it dies, but loads in under 3 seconds if it works.

  • Why does a non-dynamically created iframe shim show, but a dynamically created one does not?

    - by Carter
    I have a custom control that is made up of a text field and the ajax control toolkit dateextender. In IE6 I'm hitting the z-index bug where the calendar is showing behind select boxes. If I have the shim sitting in the control, initially hidden, it seems to display fine when the calendar is shown, but when I try to dynamically create the shim on showing it doesn't appear. I've tried bgiframe and some examples I found on SO, no luck. Here is my javascript code currently... var dateEditorShim; function dateEditor_OnShown(dateControl, emptyEventArgs) { var shimWidth = dateControl._width; var shimHeight = dateControl._height; //var dateEditorShim; //dateEditorShim = document.getElementById(dateEditorShimId); dateEditorShim = document.createElement('iframe'); dateEditorShim.setAttribute('src', 'javascript:"";'); dateEditorShim.setAttribute('frameBorder', '0'); dateEditorShim.style.width = dateControl._popupDiv.offsetWidth; dateEditorShim.style.height = dateControl._popupDiv.offsetHeight; dateEditorShim.style.top = dateControl._popupDiv.style.top; dateEditorShim.style.left = dateControl._popupDiv.style.left; dateControl._popupDiv.style.zIndex = 999; dateEditorShim.style.zIndex = 998; dateEditorShim.style.display = "block"; } function dateEditor_OnHiding(dateControl, emptyEventArgs) { var shimWidth = 0; var shimHeight = 0; //var dateEditorShim; //dateEditorShim = document.getElementById(dateEditorShimId); dateEditorShim.style.width = 0; dateEditorShim.style.height = 0; dateEditorShim.style.top = 0; dateEditorShim.style.left = 0; dateEditorShim.style.display = "none"; } You'll notice I have a commented out bit of code that gets an iframe that is embedded into the page, as I said, in this case the iframe at least shows up, but when I dynamically create it like the code above currently, it doesn't. I'm trying to figure out why. Any ideas?

  • How do I browse a Websphere MQ message without removing it?

    - by jmgant
    I'm writing a .NET Windows Forms application that will post a message to a Websphere MQ queue and then poll a different queue for a response. If a response is returned, the application will partially process the response in real time. But the response needs to stay in the queue so that a daily batch job, which also reads from the response queue, can do the rest of the processing. I've gotten as far as reading the message. What I haven't been able to figure out is how to read it without removing it. Here's what I've got so far. I'm an MQ newbie, so any suggestions will be appreciated. And feel free to respond in C#. Public Function GetMessage(ByVal msgID As String) As MQMessage Dim q = ConnectToResponseQueue() Dim msg As New MQMessage() Dim getOpts As New MQGetMessageOptions() Dim runThru = Now.AddMilliseconds(CInt(ConfigurationManager.AppSettings("responseTimeoutMS"))) System.Threading.Thread.Sleep(1000) 'Wait for one second before checking for the first response' While True Try q.Get(msg, getOpts) Return msg Catch ex As MQException When ex.Reason = MQC.MQRC_NO_MSG_AVAILABLE If Now > runThru Then Throw ex System.Threading.Thread.Sleep(3000) Finally q.Close() End Try End While Return Nothing 'Should never reach here' End Function NOTE: I haven't verified that my code actually removes the message. But that's how I understand MQ to work, and that appears to be what's happening. Please correct me if that's not the default behavior.

  • Django Testing: Faking User Creation

    - by Ygam
    I want to better write this test: def test_profile_created(self): self.client.post(reverse('registration_register'), data={ 'username':'ygam', 'email':'[email protected]', 'password1':'ygam', 'password2':'ygam' }) """ Test if a profile is created on save """ user = User.objects.get(username='ygam') self.assertTrue(UserProfile.objects.filter(user=user).exists()) and I just came upon this code on django-registration tests that does not actually "create" the user: def test_registration_signal(self): def receiver(sender, **kwargs): self.failUnless('user' in kwargs) self.assertEqual(kwargs['user'].username, 'bob') self.failUnless('request' in kwargs) self.failUnless(isinstance(kwargs['request'], WSGIRequest)) received_signals.append(kwargs.get('signal')) received_signals = [] signals.user_registered.connect(receiver, sender=self.backend.__class__) self.backend.register(_mock_request(), username='bob', email='[email protected]', password1='secret') self.assertEqual(len(received_signals), 1) self.assertEqual(received_signals, [signals.user_registered]) However he used a custom function for this "_mock_request": class _MockRequestClient(Client): def request(self, **request): environ = { 'HTTP_COOKIE': self.cookies, 'PATH_INFO': '/', 'QUERY_STRING': '', 'REMOTE_ADDR': '127.0.0.1', 'REQUEST_METHOD': 'GET', 'SCRIPT_NAME': '', 'SERVER_NAME': 'testserver', 'SERVER_PORT': '80', 'SERVER_PROTOCOL': 'HTTP/1.1', 'wsgi.version': (1,0), 'wsgi.url_scheme': 'http', 'wsgi.errors': self.errors, 'wsgi.multiprocess':True, 'wsgi.multithread': False, 'wsgi.run_once': False, 'wsgi.input': None, } environ.update(self.defaults) environ.update(request) request = WSGIRequest(environ) # We have to manually add a session since we'll be bypassing # the middleware chain. session_middleware = SessionMiddleware() session_middleware.process_request(request) return request def _mock_request(): return _MockRequestClient().request() However, it may be too long of a function for my needs. I want to be able to somehow "fake" the account creation. I have not much experience on mocks and stubs so any help would do. Thanks!

  • SubSonic generated code and always filtering records

    - by cmroanirgo
    Hi, I have a table called "Users" that has a column called "deleted", a boolean indicating that the user is "Deleted" from the system (without actually deleting it, of course). I also have a lot of tables that have a FK to the Users.user_id column. Subsonic generates (very nicely) the code for all the foreign keys in a similar manner: public IQueryable<person> user { get { var repo=user.GetRepo(); return from items in repo.GetAll() where items.user_id == _user_id select items; } } Whilst this is good and all, is there a way to generate the code in such a way to always filter out the "Deleted" users too? In the office here, the only suggestion we can think of is to use a partial class and extend it. This is obviously a pain when there are lots and lots of classes using the User table, not to mention the fact that it's easy to inadvertently use the wrong property (User vs ActiveUser in this example): public IQueryable<User> ActiveUser { get { var repo=User.GetRepo(); return from items in repo.GetAll() where items.user_id == _user_id and items.deleted == 0 select items; } } Any ideas?

  • jQuery validation plugin - removing elements

    - by d3020
    I'm using the jQuery validation plugin. On most of my input type... tags I have class='required'. When I submit the page, via JavaScript, the controls on the page that have this class are found. However, there are a handful of checkboxes that I don't need to validate. I've tried removing the class code completely from the input tag, also tried class='cancel', and class='required:false. When doing any of those things though when the form submits it can't find the checkbox control. How do I still keep the ability to do Request.Form and find my checkbox object but at the same time when the form submits don't apply validation to this particular control. Thank you. Edit here. This is what I'm using without the "checked" code and ternary operator. In my input tag I'm calling a function like this... sb.Append(" " + crlf); Inside that function is where I check for the True or False coming back, like this. case "chkFlashedCarton": strResultValue = pst.FlashedCarton.ToString(); if (strResultValue == "True") { strResultValue = " checked"; } break; strResultValue is what is returned back. Does this help to see? Thank you.
