  • Problems with Windows 7 restore

    - by Chris Lively
    My WD raptor 150 failed with a nice clicking noise. So, I picked up a velociraptor 300 and popped it in. I had windows set to do a full system backup nightly, so I figured the recovery ought to go easily. Well, it isn't. It is currently stuck on a screen that says: "Windows is restoring your computer from the system image. This might take from a few minutes to a few hours" Below that is a rather large progress meter with maybe the first block filled in. Below that is a message that says "Restoring disk (C:)..." It's been that way for over an hour. The first time around, I gave up after 2 hours. I then booted into the system recovery options and went to a command prompt and ran a chkdsk on the new drive. It showed several file inconsistencies and not much else. I ran a chkdsk /f on it and tried again... Which is where I'm at now. I can't see that the restore process should take this long before. Any ideas? UPDATE After 10 hours, it's still on "Restoring disk (C:)" and the progress meter is at roughly 5%. I'm guessing at the 5% as there isn't an actual number or anything else that I can look at showing what it's actually doing. The backup contains roughly 120GB of data. How slow is windows restore?

  • DNS propagation delay or bad configuration?

    - by Javier Martinez
    I have been waiting the DNS propagation for almost 24 hours. I'am no impatient, but I want to know if I configured my zone good or I have any error in it. I think that is good, because if I use my server dns like my DNS secondary I can resolve and lookup host well. ; ; BIND data file for mydomain.net ; $TTL 86400 @ IN SOA mydomain.net. mydomain.net. ( 20120629 ; Serial 10800 ; Refresh 3 hours 3600 ; Retry 1 hour 604800 ; Expire 1 week 86400 ) ; Negative Cache TTL ; @ IN NS ns1 @ IN NS ns2 IN MX 10 mail ns1 IN A 5.39.X.Y ns2 IN A 5.39.X.Z There is not any errors in /var/syslog about bind daemon. Is everything correct? Do I only need to wait up to 48 hours for the right DNS propagation? My nslookup from a remote machine with the nameserver of the bind host: $ nslookup mydomain.net Server: bind-host-ip Address: bind-host-ip#53 Name: mydomain.net Address: domain-ip

  • Cut (smart edit) .mts (AVCHD Progressive) files un Ubuntu Lucid

    - by pts
    I have a bunch of .mts files containing AVCHD Progressive video recorded by a Panasonic camera, and I need software on Ubuntu Lucid with which I can remove the boring parts, and concatenate the interesting parts, all this without reencoding the video stream. It's OK for me to cut at keyframe boundary. If Avidemux was able to open the files, it would take about 60 hours of work for me to cut the files. (At least that was it last time I tried with similar videos, but of a file format supported by Avidemux.) So I need a fast, powerful and stable video editor, because I don't want that 60 hours of work go up to 240 or even 480 hours just because the tool is too slow or unstable or has a terrible UI. I've tried Avidemux 2.5.5 and 2.5.6, but they crash trying to open such a file, even if I convert the file to .avi first using mencoder -oac copy -ovc copy. mplayer can play the files. I've tried Avidemux 2.6.0, which can open the file, but it cannot jump to the previous or next keyframe etc. (if I make it jump to the next keyframe, and then to the previous keyframe, it doesn't end up at the original keyframe, sometimes displays an error etc.). Also I'm not sure if Avidemux 2.6.x would let me save the result without reencoding. I've tried Kdenlive 0.7.7.1, but playback is very choppy, and it cannot play audio at all (complaining that SDL cannot find the device; but many other programs on the system can play audio). It would be a pain to work with. I've tried converting the .mts file to .mkv using ffmpeg -i input.mts -vcodec copy -sameq -acodec copy -f matroska output.mkv, but that caused too much visible distortions in the video in both mplayer and Avidemux. I've tried converting the .mts file with TsRemux.exe, but Avidemux 2.5.x still can't open that file. Is there another program to cut and concatenate the files? Is there a preprocessor which would create a file (without reencoding the video) on which Avidemux wouldn't crash?

  • apache chokes after 300 connections

    - by john titus
    We have an apache webserver in front of Tomcat hosted on EC2, instance type is extra large with 34GB memory. Our application deals with lot of external webservices and we have a very lousy external webservice which takes almost 300 seconds to respond to requests during peak hours. During peak hours the server chokes at just about 300 httpd processes. ps -ef | grep httpd | wc -l =300 I have googled and found numerous suggestions but nothing seems to work.. following are some configuration i have done which are directly taken from online resources. I have increased the limits of max connection and max clients in both apache and tomcat. here are the configuration details: //apache <IfModule prefork.c> StartServers 100 MinSpareServers 10 MaxSpareServers 10 ServerLimit 50000 MaxClients 50000 MaxRequestsPerChild 2000 </IfModule> //tomcat <Connector port="8080" protocol="org.apache.coyote.http11.Http11NioProtocol" connectionTimeout="600000" redirectPort="8443" enableLookups="false" maxThreads="1500" compressableMimeType="text/html,text/xml,text/plain,text/css,application/x-javascript,text/vnd.wap.wml,text/vnd.wap.wmlscript,application/xhtml+xml,application/xml-dtd,application/xslt+xml" compression="on"/> //Sysctl.conf net.ipv4.tcp_tw_reuse=1 net.ipv4.tcp_tw_recycle=1 fs.file-max = 5049800 vm.min_free_kbytes = 204800 vm.page-cluster = 20 vm.swappiness = 90 net.ipv4.tcp_rfc1337=1 net.ipv4.tcp_max_orphans = 65536 net.ipv4.ip_local_port_range = 5000 65000 net.core.somaxconn = 1024 I have been trying numerous suggestions but in vain.. how to fix this? I'm sure m2xlarge server should serve more requests than 300, probably i might be going wrong with my configuration.. The server chokes only during peak hours and when there are 300 concurrent requests waiting for the [300 second delayed] webservice to respond. Please help..

  • Why does loading a html page opens automaically the printer dialog?

    - by Alex
    I have the problem that loading a certain webpage in firefox automatically opens the printer dialog. How is that? Additional information: This only happens on firefox 24.0 on Windows 7. It neither happens on Windows Explorer in Windows 7 nor on Firefox 24 on a Linux system. This also happens when using the firefox safemode, with all add-ons disabled. I cannot post the webpage, since it is not public and restricted. Multiple javascript files are used, but none contains the expression print(). The page content does not contain the phrase 'printer'. It has nothing to do with printing something. This happens sometimes, but not always. I cannot say for sure the URL and/or the content is always identical. I can answer any other questions, like 'Does the page contain this and that...', 'does the URL contain this and that...' Basic question: What could be the reason for the annoying printer pop up?

  • How to mix C++ Qt objects and Qt Jambi objects

    - by Dan
    Hi, I'm trying to combine some existing Qt code written in C++ with some code written in Java using Qt Jambi, but I'm not quite sure how to do it. I'm basically trying to acieve two things: Pass a QObject from C++ to Java using JNI Pass a Qt Jambi QObject from Java to C++ It looks like I can pass the pointer directly and then wrap it in QNativePointer on the Java side, but I can't figure out how to turn a QNativePointer back into the original object, wrapped by Qt Jambi. Eg: I can pass a QWidget* as a long to Java and then create a QNativePointer in Java, but how can I then construct a QWidget out of this? QJambiObject and QObject dont seem to have a "setNativePointer" method and I'm not sure how to convert it. In C++: QWidget* widget = ... jclass cls = env->FindClass("Test"); jmethodID mid = env->GetStaticMethodID(cls, "test", "(I)V"); env->CallStaticVoidMethod(cls, mid, int(widget)); In Java: public class Test { public static void test (int ptr) { QNativePointer pointer = new QNativePointer(QNativePointer.Type.Int); pointer.setIntValue(ptr); QWidget widget = ... Thanks!

  • Tricky SQL query involving consecutive values

    - by Gabriel
    I need to perform a relatively easy to explain but (given my somewhat limited skills) hard to write SQL query. Assume we have a table similar to this one: exam_no | name | surname | result | date ---------+------+---------+--------+------------ 1 | John | Doe | PASS | 2012-01-01 1 | Ryan | Smith | FAIL | 2012-01-02 <-- 1 | Ann | Evans | PASS | 2012-01-03 1 | Mary | Lee | FAIL | 2012-01-04 ... | ... | ... | ... | ... 2 | John | Doe | FAIL | 2012-02-01 <-- 2 | Ryan | Smith | FAIL | 2012-02-02 2 | Ann | Evans | FAIL | 2012-02-03 2 | Mary | Lee | PASS | 2012-02-04 ... | ... | ... | ... | ... 3 | John | Doe | FAIL | 2012-03-01 3 | Ryan | Smith | FAIL | 2012-03-02 3 | Ann | Evans | PASS | 2012-03-03 3 | Mary | Lee | FAIL | 2012-03-04 <-- Note that exam_no and date aren't necessarily related as one might expect from the kind of example I chose. Now, the query that I need to do is as follows: From the latest exam (exam_no = 3) find all the students that have failed (John Doe, Ryan Smith and Mary Lee). For each of these students find the date of the first of the batch of consecutively failing exams. Another way to put it would be: for each of these students find the date of the first failing exam that comes after their last passing exam. (Look at the arrows in the table). The resulting table should be something like this: name | surname | date_since_failing ------+---------+-------------------- John | Doe | 2012-02-01 Ryan | Smith | 2012-01-02 Mary | Lee | 2012-01-04 Ann | Evans | 2012-02-03 How can I perform such a query? Thank you for your time.

  • Unit Testing - Validation of ViewModel ASP.NET MVC 2

    - by dean nolan
    I am currently unit testing a service that adds users to a repository. I am using dependency injection to test using a fake repository. The repository has a method CreateUser(User user) which just adds it to the database or in this case a List of Users. The logic for the creation is in the UserServices class. The application has a form for creating a user that requires some properties such as name and address. This is an MVC 2 app and I will be using the new validation using data annotations. This makes me wonder about a few things: 1) Should I annotate a POCO object that will map to the database? Or should I create a specific View Model that has these annotations and pass this data to the UserServices class? 2)Should the UserServicesClass also check this data? Would I best be constructing a Usr out of the ViewModel and passing this into the Service as a parameter? 3) The actual unit testing would depend on 2), I either populate a User object and pass that in, or I pass a large list of strings to the method CreateUser. Writing this out I get a basic idea that I should probably annotate the view model only, pass in a user (constructed by the view model if the data is valid) and also just construct the user in the unit test also. Is this the best way to go?

  • SQL Server Trouble with Rails

    - by Earlz
    Ok, I've been trying to get this to work like all day now and I'm barely any further from when I started. I'm trying to get Ruby On Rails to connect to SQL Server. I've installed unixODBC and configured it and FreeTDS and installed just about every Ruby gem relating to ODBC that exists. [earlz@earlzarch myproject]$ tsql -S AVP1 -U sa -P pass locale is "en_US.UTF-8" locale charset is "UTF-8" 1> quit [earlz@earlzarch myproject]$ isql AVP1 sa pass [ISQL]ERROR: Could not SQLConnect [earlz@earlzarch myproject]$ rake db:version (in /home/earlz/myproject) rake aborted! IM002 (0) [unixODBC][Driver Manager]Data source name not found, and no default driver specified (See full trace by running task with --trace) so, as you can see, tsql works, but not isql. What is the difference in the two that breaks it? /etc/odbc.ini [AVP1] Description = ODBC connection via FreeTDS Driver = TDS Servername = my.server UID = sa PWD = pass port = 1232 Database = mydatabase /etc/odbcinst.ini [TDS] Description = v0.6 with protocol v7.0 Driver = /usr/lib/libtdsodbc.so Setup = /usr/lib/libtdsS.so CPTimeout = CPReuse = FileUsage = 1 (and yes, I've made sure that the .so files exist) the relevant part in freetds.conf [AVP1] host = my.server port = 1232 tds version = 8.0 and finally, my database.yml development: adapter: sqlserver mode: odbc dsn: AVP1 username: sa password: pass Can anyone please help me before I pull all my hair out?

  • Ajax/PHP contact form not able to send mail

    - by Steph
    The funny thing is it did work for one evening. I contacted my host, and they are saying there's no reason it should not be working. I have also attempted to test it in Firebug, but it seemed to be sending. And I specifically put the email address (hosted in my domain) on my email safe list, so that is not the culprit either. Would anyone here take a look at it for me? I'd be so grateful. In the header I have: <script type="text/javascript"> $(document).ready(function() { var options = { target: '#alert' }; $('#contactForm').ajaxForm(options); }); $.fn.clearForm = function() { return this.each(function() { var type = this.type, tag = this.tagName.toLowerCase(); if (tag == 'form') return $(':input',this).clearForm(); if (type == 'text' || type == 'password' || tag == 'textarea') this.value = ''; else if (type == 'checkbox' || type == 'radio') this.checked = false; else if (tag == 'select') this.selectedIndex = -1; }); }; </script> Here is the actual form: <form id="contactForm" method="post" action="sendmail.php"> <fieldset> <p>Email Me</p> <div id="fieldset_container"> <label for="name">Your Name:</label> <input type="text" name="name" id="name" /><br /><br /> <label for="email">Email:</label> <input type="text" name="email" id="email" /><br /><br /> <span style="display:none;"> <label for="last">Honeypot:</label> <input type="text" name="last" value="" id="last" /> </span><br /><br /> <label for="message">Comments &amp; Inquiries:</label> <textarea name="message" id="message" cols="" rows=""></textarea><br/> </div> <div id="submit_button"> <input type="submit" name="submit" id="submit" value="Send It" /> </div> </fieldset> </form> <div class="message"><div id="alert"></div></div> Here is the code from my validating page, sendmail.php: <?php // Who you want to recieve the emails from the form.

  • How can I get browser to prompt to save password?

    - by Eric
    Hey, I'm working on a web app that has a login dialog that works like this: User clicks "login" Login form HTML is loaded with AJAX and displayed in DIV on page User enters user/pass in fields and clicks submit. It's NOT a <form> -- user/pass are submitted via AJAX If user/pass are okay, page reloads with user logged in. If user/pass are bad, page does NOT reload but error message appears in DIV and user gets to try again. Here's the problem: the browser never offers the usual "Save this password? Yes / Never / Not Now" prompt that it does for other sites. I tried wrapping the <div> in <form> tags with "autocomplete='on'" but that made no difference. Is it possible to get the browser to offer to store the password without a major rework of my login flow? thanks Eric p.s. to add to my question, I'm definitely working with browers that store passwords, and I've never clicked "never for this site" ...this is a technical issue with the browser not detecting that it's a login form, not operator error :-)

  • Problem with JMX query of Coherence node MBeans visible in JConsole

    - by Quinn Taylor
    I'm using JMX to build a custom tool for monitoring remote Coherence clusters at work. I'm able to connect just fine and query MBeans directly, and I've acquired nearly all the information I need. However, I've run into a snag when trying to query MBeans for specific caches within a cluster, which is where I can find stats about total number of gets/puts, average time for each, etc. The MBeans I'm trying to access programatically are visible when I connect to the remote process using JConsole, and have names like this: Coherence:type=Cache,service=SequenceQueue,name=SEQ%GENERATOR,nodeId=1,tier=back It would make it more flexible if I can dynamically grab all type=Cache MBeans for a particular node ID without specifying all the caches. I'm trying to query them like this: QueryExp specifiedNodeId = Query.eq(Query.attr("nodeId"), Query.value(nodeId)); QueryExp typeIsCache = Query.eq(Query.attr("type"), Query.value("Cache")); QueryExp cacheNodes = Query.and(specifiedNodeId, typeIsCache); ObjectName coherence = new ObjectName("Coherence:*"); Set<ObjectName> cacheMBeans = mBeanServer.queryMBeans(coherence, cacheNodes); However, regardless of whether I use queryMBeans() or queryNames(), the query returns a Set containing... ...0 objects if I pass the arguments shown above ...0 objects if I pass null for the first argument ...all MBeans in the Coherence:* domain (112) if I pass null for the second argument ...every single MBean (128) if I pass null for both arguments The first two results are the unexpected ones, and suggest a problem in the QueryExp I'm passing, but I can't figure out what the problem is. I even tried just passing typeIsCache or specifiedNodeId for the second parameter (with either coherence or null as the first parameter) and I always get 0 results. I'm pretty green with JMX — any insight on what the problem is? (FYI, the monitoring tool will be run on Java 5, so things like JMX 2.0 won't help me at this point.)

  • Flash Builder 4: Call main function from a component function

    - by hyper
    i try to make a login sistem in flex, and my app looks like this: i have a main.mxml. when the app loads, a function named "start" is called. it verifies if the user is logged in or not. if "true" the user is redirected to a dashboard, if "false", a component named login is loaded. my login.mxml component has 2 input boxes (user & pass) and a "Submit" button. when the button is pressed a function named "send_login" sends the user and the pass values to the server. My problem sounds like this: when i press the Submit button in my login component, after user and pass are sended... i want to call again the "start" function from my main.mxml to check again if the user is logged in or not... i need some kind of as2 "_root" this is how my code looks: main.mxml public function start():void { currentState="Start"; loginstatus(); } login.mxml private function send_login(event:Event):void { ... bla bla send user and pass.... scriptLoader.addEventListener(Event.COMPLETE, handleLoadSuccessful); } private function handleLoadSuccessful(evt:Event):void { trace("Data sent."); start(); <-- HERE i want to call the function from main.mxml } any help is welcomed!

  • APS.NET MVC Ajax: Passing a IList from the View to the Controller

    - by Bpimenta
    I need to pass the grid rows from the view to the controller using POST. The idea is to pass an IList of objects (people) that have the following structure: String Name String Address String ID I want to read the data from the JQGrid and pass it to the controller to fill the IList. I'm trying to build the data object to pass through the Ajax data parameter. Here is the Javascript code: $("#saveButton").click( function() { var returnData = '{'; var existingIDs = $('#listPeople').getDataIDs(); if (idsPeople.length > 0) { for (i=0;i<idsPeople.length;i++) { //Trying to build the obejct data ret = ret + '"people['+ i +'].Name":' $('#listPeople').getRowData(idsPeople[i]).Name + ','; ret = ret + '"people['+ i +'].Address":' $('#listPeople').getRowData(idsPeople[i]).Address+ ','; ret = ret + '"people['+ i +'].Id":' $('#listPeople').getRowData(idsPeople[i]).Id+ ','; //If it has more than one element if (idsPeople.length>1 && (i+1)<idsPeople.length) { ret = ret + ','; } } } ret = ret + '}'; My Ajax function for sending: var url_all = '<%=Url.Action("SaveData") %>; $.ajax({ type: "POST", url: url_all, data: ret, dataType: "json", success: function(){ alert("OK"); }, error: function(){ alert("Error: check SaveData"); } }); My controller: public ActionResult SaveData(IList<PeopleHeader> people){ // using debug to know if "people" variable has any values return Json(true); } The problem I'm getting is an error: "System.NotSupportedException: Fixed size collection", and no data is being delivered. I think my problem relies on creating the object... is there any simpler way of doing this procedure? Thanks in advance,

  • Passing data between ViewControllers versus doing local Fetch in each VC

    - by Tofrizer
    Hi All, I'm developing an iPhone app using Core Data and I'm looking for some general advice and recommendations on whether its acceptable to pass data between ViewControllers versus doing a local fetch in each ViewController as you navigate to it. Ordinarily I would say it all depends on various factors (e.g. performance etc) but the passing data approach is so prevalent in my app and I'm spooked by all the stories about Apple rejecting apps because of not conforming to their standard guidelines. So let me put another way -- is it non-standard to pass data between VC's? The reason I pass data so much is because each ViewController is just another view on to data present in my object model / graph. Once I have a handle on my first object in the first view controller (which I of course do have to fetch), I can use the existing object composition / relationships to drill down into the next level of detail into data and so I just pass these objects to the next VC. Separately, one possible downside with this passing-data-to-each-VC approach is I don't benefit from (what I perceive to be) the optimisation/benefits that NSFetchedResultsController provides in terms of efficient memory usage and section handling. My app is read-only but I do have one table with 5000 rows and I'm curious if I am missing out on NSFetchedResultsController benefits. Any thoughts on this as well? Can I somehow still benefit from NSFetchedResultsController goodness without having to do a full fetch (as I would have already passed in the data from my previous VC)? Thanks a lot.

  • How do I display a view as if it's the front page via a module?

    - by Justin
    I have a simple view that feeds a home page. I have a custom module that registers some specific URLs in hook_menu that I pass into my module so I can pass them as arguments into the view. I can get the module to display the view all right, but it doesn't use the teaser/is_front view that outputs when I access the home page. I looked through the APIs but I can't seem to figure out how I can output the view via my module as if it's the front page, meaning $is_front is true and the teasers would appear. The reason I'm not passing in the arguments via the URL bar into the view itself is: My argument list is known and finite The argument order is mixed, meaning I will sometimes have /argument1, /argument1/argument2 or just /argument2. I only want to capture the first level URL as an argument for specific, known strings (e.g. I don't want to pass /admin into my view but I do want to pass in /los-angeles, which I register in the menu system via hook_menu in my module) Here are some examples to make this more clear: /admin - loads the admin page /user - loads the login page /boston - passes into the first argument of the view; shows in front/teaser mode / - shows view with no arguments /bread - passes into argument 2 of the view; shows in front/teaser mode /boston/bread - Passes into argument 1 and 2 of the view; shows in front/teaser mode Maybe I'm going about this the wrong way? Or perhaps there is a way to have a module load a view and somehow set front/teaser mode? Details: Drupal 6, PHP 5, MySQL 5, Views, CCK

  • Render multiple Form instances

    - by vorpyg
    I have a simple application where users are supposed to bet on outcome of a match. A match consists of two teams, a result and a stake. Matches with teams are created in the Django admin, and participants are to fill in result and stake. The form must be generated dynamically, based on the matches in the database. My idea is to have one (Django) Form instance for each match and pass these instances to the template. It works fine when I do it from django shell, but the instances aren't rendered when I load my view. The form looks like this: class SuggestionForm(forms.Form): def __init__(self, *args, **kwargs): try: match = kwargs.pop('match') except KeyError: pass super(SuggestionForm, self).__init__(*args, **kwargs) label = match self.fields['result'] = forms.ChoiceField(label=label, required=True, choices=CHOICES, widget=forms.RadioSelect()) self.fields['stake'] = forms.IntegerField(label='', required=True, max_value=50, min_value=10, initial=10) My (preliminary) view looks like this: def suggestion_form(request): matches = Match.objects.all() form_collection = {} for match in matches: f = SuggestionForm(request.POST or None, match=match) form_collection['match_%s' % match.id] = f return render_to_response('app/suggestion_form.html', { 'forms': form_collection, }, context_instance = RequestContext(request) ) My initial thought was that I could pass the form_collection to the template and the loop throught the collection like this, but id does not work: {% for form in forms %} {% for field in form %} {{ field }} {% endfor %} {% endfor %} (The output is actually the dict keys with added spaces in between each letter - I've no idea why…) It works if I only pass one Form instance to the template and only runs the inner loop. Suggestions are greatly appreciated.

  • Java function changing input

    - by Doodle
    I would like to go from one number to another. For example if I started at 6 and my goal was 10 I want a function that on every pass would bring me from 6 towards 10 or if I had the number 14 and my goal was 9 it would count down from 14 towards 9.So far I have (this is written in Processing a Java Api but there is essentially no difference from regualr Java, draw is just a continuous loop) int x=100; void draw(){ x=towards(x,10); println(x); } int towards(int current ,int target){ if(current!=target){ if (current <target){ current=current+1; } else { current=current-1; } } return current; } this gives me the results I would like but I would like to have everything in side of the towards() function. When I replace X with a variable it of course resets it self to the static variable. To sum it up how can I pass a variable to a function and have that variable thats been passed change on every subsequent pass. I have looked into recursion as a solution but that of just brings me to a final solution. I can pass the count to an array but wouldn't like to do that either.

  • iphone - grouping UIImageViews x blocking elements

    - by Mike
    I have to rotate several UIImageViews around a specific center. To accomplish this I am using the famous trick of putting these views as subviews of a larger one and rotating that one. The problem is that these subviews have to detect touches, because each one has buttons on it. The hierarchy is like this LARGE_VIEW | |_____ imageView1 | |_________ button1 | |_________ button2 | |_________ button3 | |_____ imageView2 |_________ button4 |_________ button5 |_________ button6 etc So, to make buttons respond to tap, I had to make this; [LARGE_VIEW setUserInteractionEnabled:YES]; [imageView1 setUserInteractionEnabled:YES]; [imageView2 setUserInteractionEnabled:YES]; ImageView1 and 2 are two vertical rows of buttons on each side of the screen. The problem is that there's another view below LARGE_VIEW and this view is not receiving the taps, because LARGE_VIEW is intercepting them first. I don't need LARGE_VIEW to detect any taps except on the two areas where imageView 1 and 2 are. LARGE_VIEW must let pass taps on the area defined by this rect (52, 0, 768-2*52, 1024). ImageView1 and 2 have this size: 52 pixels wide and 1024 pixels high (iPad). ImageView1's rect is: (0, 0, 52, 1024) and ImageView2's rect is: (768-52, 0, 52, 1024) LARGE_VIEW must let pass taps on the area defined by this rect (52, 0, 768-2*52, 1024). How to solve that? I need LARGE_VIEW detect taps on each rect defined on my previous paragraph and pass these taps to its subviews and just let pass taps outside these rects to the app, so other views BELOW, can detect taps too. thanks.

  • I have a problem with mysql and php

    - by neo skosana
    Hi I have a problem, this is my code: $db = new mysqli("localhost", "root", "", "blah"); $result1 = $db-query("select * from c_register where email = '$eml' and password = '$pass'"); if($result1-fetch_array()) { $auth->createSession(); $_SESSION['user'] = 'client'; promptUser("You have successfully logged in!!!","index.php"); } $db = new mysqli("localhost", "root", "", "blah"); $result2 = $db-query("select * from b_register where email = '$eml' and password = '$pass'"); if($result2-fetch_array()) { $auth->createSession(); $_SESSION['user'] = 'business'; promptUser("You have successfully logged in!!!","index.php"); } $db = new mysqli("localhost", "root", "", "blah"); $result3 = $db-query("select * from g_register where email = '$eml' and password = '$pass'"); if($result3-fetch_array()) { $auth->createSession(); $_SESSION['user'] = 'employee'; promptUser("You have successfully logged in!!!","index.php"); } $db = new mysqli("localhost", "root", "", "blah"); $result4 = $db-query("select * from k_register where email = '$eml' and password = '$pass'"); if($result4-fetch_array()) { $auth->createSession(); $_SESSION['user'] = 'super'; promptUser("You have successfully logged in!!!","index.php"); } else { promptUser("Username/Password do not match.

  • How to specify multiple values in where with AR query interface in rails3

    - by wkhatch
    Per section 2.2 of rails guide on Active Record query interface here: which seems to indicate that I can pass a string specifying the condition(s), then an array of values that should be substituted at some point while the arel is being built. So I've got a statement that generates my conditions string, which can be a varying number of attributes chained together with either AND or OR between them, and I pass in an array as the second arg to the where method, and I get: ActiveRecord::PreparedStatementInvalid: wrong number of bind variables (1 for 5) which leads me to believe I'm doing this incorrectly. However, I'm not finding anything on how to do it correctly. To restate the problem another way, I need to pass in a string to the where method such as "table.attribute = ? AND table.attribute1 = ? OR table.attribute1 = ?" with an unknown number of these conditions anded or ored together, and then pass something, what I thought would be an array as the second argument that would be used to substitute the values in the first argument conditions string. Is this the correct approach, or, I'm just missing some other huge concept somewhere and I'm coming at this all wrong? I'd think that somehow, this has to be possible, short of just generating a raw sql string.

  • Which design pattern fits - strategy makes sense ?

    - by user554833
    --Bump *One desperate try to get someone's attention I have a simple database table that stores list of users who have subscribed to folders either by email OR to show up on the site (only on the web UI). In the storage table this is controlled by a number(1 - show on site 2- by email). When I am showing in UI I need to show a checkbox next to each of folders for which the user has subscribed (both email & on site). There is a separate table which stores a set of default subscriptions which would apply to each user if user has not expressed his subscription. This is basically a folder ID and a virtual group name. But, Email subscriptions do not count for applying these default groups. So if no "on site" subscription apply default group. Thats the rule. How about a strategy pattern here (Pseudo code) Interface ISubscription public ArrayList GetSubscriptionData(Pass query object) Public class SubscriptionWithDefaultGroup Implement ArrayList GetSubscriptionData(Pass query object) Public class SubscriptionWithoutDefaultGroup Implement ArrayList GetSubscriptionData(Pass query object) Public class SubscriptionOnlyDefaultGroup Implement ArrayList GetSubscriptionData(Pass query object) does this even make sense? I would be more than glad for receive any criticism / help / notes. I am learning. Cheers

  • [SOLVED]Django - Passing variables to template based on db

    - by George 'Griffin
    I am trying to add a feature to my app that would allow me to enable/disable the "Call Me" button based on whether or not I am at [home|the office]. I created a model in the database called setting, it looks like this: class setting(models.Model): key = models.CharField(max_length=200) value = models.CharField(max_length=200) Pretty simple. There is currently one row, available, the value of it is the string True. I want to be able to transparently pass variables to the templates like this: {% if available %} <!-- Display button --> {% else %} <!-- Display grayed out button --> {% endif %} Now, I could add logic to every view that would check the database, and pass the variable to the template, but I am trying to stay DRY. What is the best way to do this? UPDATE I created a context processor, and added it's path to the TEMPLATE_CONTEXT_PROCESSORS, but it is not being passed to the template def available(request): available = Setting.objects.get(key="available") if open.value == "True": return {"available":True} else: return {} UPDATE TWO If you are using the shortcut render_to_response, you need to pass an instance of RequestContext to the function. from the django documentation: If you're using Django's render_to_response() shortcut to populate a template with the contents of a dictionary, your template will be passed a Context instance by default (not a RequestContext). To use a RequestContext in your template rendering, pass an optional third argument to render_to_response(): a RequestContext instance. Your code might look like this: def some_view(request): # ... return render_to_response('my_template.html', my_data_dictionary, context_instance=RequestContext(request)) Many thanks for all the help!
