  • MVC2 Client Validation isn't working when getting form from ajax call

    - by devlife
    I'm trying to use MVC2 client-side validation in a partial view that is rendered via $.get. However, the client validation isn't working. I'm not quite sure what the deal is. [Required(ErrorMessage = "Email is required")] public string Email { get; set; } <% using ( Ajax.BeginForm( new AjaxOptions { Confirm = "You sure?" } ) ) { %> <%: Html.TextBoxFor( m => m.Email, new { @class = "TextBox150" } )%> <%= Html.ValidationMessageFor( m => m.Email )%> <input type="submit" value="Add/Save" style="float: right;" /> <% } %> I'm not doing anything special to render the the partial view. Just putting the html into a div and showing it in a modal popup. On a side note, does anyone know if it's possible to submit the form with client validation without a submit button?

  • multiple login pages in ASP.NET forms authentication

    - by Brad
    My bank's website has 2 login pages for online banking. On the first page, I enter my username. If I don't enter a valid username, I get an error message, and do not get to the 2nd page. The 2nd page displays a picture based on my user name, and has me enter my password. If I manually type a URL to a page inside the site after entering my username but before entering my password, I am redirected back to the first login page. Is there a good way to implement this in ASP.NET with Forms Authentication? I only get 1 loginUrl in my web.config. I am fairly certain my bank uses Java.

  • Got a table of people, who I want to link to each other, many-to-many, with the links being bidirect

    - by dflock
    Imagine you live in very simplified example land - and imagine that you've got a table of people in your MySQL database: create table person ( person_id int, name text ) select * from person; +-------------------------------+ | person_id | name | +-------------------------------+ | 1 | Alice | | 2 | Bob | | 3 | Carol | +-------------------------------+ and these people need to collaborate/work together, so you've got a link table which links one person record to another: create table person__person ( person__person_id int, person_id int, other_person_id int ) This setup means that links between people are uni-directional - i.e. Alice can link to Bob, without Bob linking to Alice and, even worse, Alice can link to Bob and Bob can link to Alice at the same time, in two separate link records. As these links represent working relationships, in the real world they're all two-way mutual relationships. The following are all possible in this setup: select * from person__person; +---------------------+-----------+--------------------+ | person__person_id | person_id | other_person_id | +---------------------+-----------+--------------------+ | 1 | 1 | 2 | | 2 | 2 | 1 | | 3 | 2 | 2 | | 4 | 3 | 1 | +---------------------+-----------+--------------------+ For example, with person__person_id = 4 above, when you view Carol's (person_id = 3) profile, you should see a relationship with Alice (person_id = 1) and when you view Alice's profile, you should see a relationship with Carol, even though the link goes the other way. I realize that I can do union and distinct queries and whatnot to present the relationships as mutual in the UI, but is there a better way? I've got a feeling that there is a better way, one where this issue would neatly melt away by setting up the database properly, but I can't see it. Anyone got a better idea?

  • I can't get datepicker to work

    - by vikitor
    Hi, I need a field that displays the datepicker. I followed the example given by the JQuery UI documentation and haven't managed to get it to work. My html where I have my text field is: <div class="editor-field"> <input type = "text" name = "DatePublished" id = "Published" /> <%= Html.ValidationMessage("DatePublished" ,"*") %> </div> This HTML is in a partial view, lets call it pv.ascx, and it is called in the main page as a modal box: <div id = "ModalBox"> <% Html.RenderAction("pv", "Example"); %> </div> The thing is, that I try to call the datepicker creation anytime I enter the main page, and I do it in my javascript file app.js: $().ready(function() { var place = window.location.pathname; var placesplit = place.split("/"); //Depending on the location we are on, we execute different subroutines $('#Published').datepicker(); }); But nothing happens when I focus on the text field. What is wrong? Could it be that being called from a partial view it doesn't work? Thank you everyone, vikitor

  • Copying (or recovering) a .PFX password to another machine?

    - by Adam Robinson
    First things first, I'm aware of all of the finger-wagging potential that this question provides. However, I'm attempting to help out a friend with a project so I haven't been part of the decision making process thus far. I'm attempting to set up a new development machine, but one of the projects is signed with a .PFX key that's password protected and the original developer does not remember the password. The current development machine can open and build the project just fine, so I'm wondering if there is any way either to copy or to recover the saved password that Visual Studio is using on the original box so that the file can be used on the new box. Signing with a new file is obviously an option, but one that we'd prefer to avoid. Does anyone know of a way either to recover or copy the credentials for this file to a new machine?

  • Optimizing Haskell code

    - by Masse
    I'm trying to learn Haskell and after an article in reddit about Markov text chains, I decided to implement Markov text generation first in Python and now in Haskell. However I noticed that my python implementation is way faster than the Haskell version, even Haskell is compiled to native code. I am wondering what I should do to make the Haskell code run faster and for now I believe it's so much slower because of using Data.Map instead of hashmaps, but I'm not sure I'll post the Python code and Haskell as well. With the same data, Python takes around 3 seconds and Haskell is closer to 16 seconds. It comes without saying that I'll take any constructive criticism :). import random import re import cPickle class Markov: def __init__(self, filenames): self.filenames = filenames self.cache = self.train(self.readfiles()) picklefd = open("dump", "w") cPickle.dump(self.cache, picklefd) picklefd.close() def train(self, text): splitted = re.findall(r"(\w+|[.!?',])", text) print "Total of %d splitted words" % (len(splitted)) cache = {} for i in xrange(len(splitted)-2): pair = (splitted[i], splitted[i+1]) followup = splitted[i+2] if pair in cache: if followup not in cache[pair]: cache[pair][followup] = 1 else: cache[pair][followup] += 1 else: cache[pair] = {followup: 1} return cache def readfiles(self): data = "" for filename in self.filenames: fd = open(filename) data += fd.read() fd.close() return data def concat(self, words): sentence = "" for word in words: if word in "'\",?!:;.": sentence = sentence[0:-1] + word + " " else: sentence += word + " " return sentence def pickword(self, words): temp = [(k, words[k]) for k in words] results = [] for (word, n) in temp: results.append(word) if n > 1: for i in xrange(n-1): results.append(word) return random.choice(results) def gentext(self, words): allwords = [k for k in self.cache] (first, second) = random.choice(filter(lambda (a,b): a.istitle(), [k for k in self.cache])) sentence = [first, second] while len(sentence) < words or sentence[-1] is not ".": current = (sentence[-2], sentence[-1]) if current in self.cache: followup = self.pickword(self.cache[current]) sentence.append(followup) else: print "Wasn't able to.

  • iphone download several files

    - by Floo
    hi all !  In my app i need to download several plist.  to download a plist i use the NSURLconnection  in my code i use an UIAlertView with a UIActivityIndicator then when the download is finished i add a button to the alert to dismiss it.  To download the plist i use somewhere in my code an NSURL set to the adresse where the plist is, next i set a NSURLRequest with the url cache policy and a timeout interval.  Then i set my NSMutableData to the NSURL connection with a NSURLRequest.  In the delegate didReceiveData: i append data to my mutable data object, in the didFailWithError: i handle error. And finaly in the connectionDidFinishLoading  i serialize my data to a plist so i can write to file my plist, and release my alertview.  My problem is : how can i do if i have sevetal file to download because the connectionDidFinishLoading is called each time my NSURLConnection is finished but i want to release my UiAlert when everything is finished. But when the first plist is downloaded my code in the connectionDidFinishLoading will fire.  here is my code :  in the view did load :  // set the UiAlert in the view did load  NSURL *theUrl = [NSURL URLWithString:@"http://adress.com/plist/myPlist.plist"]; NSURLRequest *theRequest = [NSURLRequest requestWithURL:theUrl cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:60.0]; self.plistConnection = [[ NSURLConnection alloc] initwithRequest:theRequest delegate:self startImmediatly:YES]; //plistConnection is a NSURLConnection - (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data {  [incomingPListData appendData:data]; } -(void)connection:(NSURLConnection *)connectionDidFailWithError:(NSError *)error { // handle error here  } -(void)connectionDidFinisloading:(NSURLConnection *) connection {  NSPropertyListFormat format; NSString *serialErrorString;  NSData *plist = [NSPropertyListSerialisation propertyListFromData:incomingPlistData mutabilityOption:NSPropertyListImmutable format:&format errorDescription:&serialErrorString]; if (serialErrorString) {//error} else { // create path and write plist to path} // change message and title of the alert so if i want todownload an another file  where do i put the request the connection and how can i tell the didFinishLoading to fire code when all my file are downloaded.  thanks to all

  • How do I keep existing values from shifting to the right when entering keypresses into a jQuery Mask

    - by Andrew
    I have a text box I'm using as a timer display "hh:mm:ss" When I select the box and press a number, it inserts the number at the cursor location, but instead of replacing the value at that position, it shifts all existing values over. For example, the timer text box reads "01:00:35" and I replace the first minute position with 1, the timer text box will then read "01:10:03." Anybody know how to force the text box to replace, instead of insert, at the cursor position? I've tried intercepting onKeyPress, doing the replace manually, rewriting the entire timer text, and then returning false. But, that doesn't worked with a jQuery masked input, because my function runs first.

  • Is ASP.NET MVC is really MVC? Or how to separate model from controller?

    - by Andrey
    Hi all, This question is a bit rhetorical. At some point i got a feeling that ASP.NET MVC is not that authentic implementation of MVC pattern. Or i didn't understood it. Consider following domain: electric bulb, switch and motion detector. They are connected together and when you enter the room motion detector switches on the bulb. If i want to represent them as MVC: switch is model, because it holds the state and contains logic bulb is view, because it presents the state of model to human motion detector is controller, because it converts user actions to generic model commands Switch has one private field (On/Off) as a State and two methods (PressOn, PressOff). If you call PressOn when it is Off it goes to On, if you call it again state doesn't change. Bulb can be replaced with buzzer, motion detector with timer or button, but the model still represent the same logic. Eventually system will have same behavior. This is how i understand classical MVC decomposition, please correct me if i am wrong. Now let's decompose it in ASP.Net MVC way. Bulb is still a view Controller will be switch + motion detector Model is some object that will just pass state to bulb. So the logic that defines behavior moves to controller. Question 1: Is my understanding of MVC and ASP.NET MVC correct? Question 2: If yes, do you agree that ASP.NET MVC is not 100% accurate implementation? And back to life. The final question is how to separate model from controller in case of ASP.NET MVC. There can be two extremes. Controller does basic stuff and call model to do all the logic. Another is controller does all the logic and model is just something like class with properties that is mapped to DB. Question 3: Where should i draw the line between this extremes? How to balance? Thanks, Andrey

  • Most efficient way to extract bit flags

    - by Hallik
    I have these possible bit flags. 1, 2, 4, 8, 16, 64, 128, 256, 512, 2048, 4096, 16384, 32768, 65536 So each number is like a true/false statement on the server side. So if the first 3 items, and only the first 3 items are marked "true" on the server side, the web service will return a 7. Or if all 14 items above are true, I would still get a single number back from the web service which is is the sum of all those numbers. What is the best way to handle the number I get back to find out which items are marked as "true"?

  • Jqeury Validate() special function

    - by kevin
    Hi there, i'm using the Jquery validate() plugin for some forms and it goes great. The only thing is that i have an input field that requires a special validation process. Here is how it goes: The Jquery validate plugin is called in the domready for all the required fields. Here is an exemple for an input: <li> <label for="nome">Nome completo*</label> <input name="nome" type="text" id="nome" class="required"/> </li> And here is how i call my special function: <li> <span id="sprytextfield1"> <label for="cpf">CPF* (xxxxxxxxxxx)</label> <input name="cpf" type="text" id="cpf" maxlength="15" class="required" /> <span class="textfieldInvalidFormatMsg">CPF Inv&aacute;lido.</span> </span> </li> And at the bottom of the file i call the Spry function: <script type="text/javascript"> <!-- var sprytextfield1 = new Spry.Widget.ValidationTextField("sprytextfield1","cpf"); //--> </script> Of course i call the Spry css and js files in the head section as well as my special-validate.js. When i just use the Jquery validate() plugin and click on the send button, the page goes automatically back to the first mistaken input field and shows the error type (not a number, not a valid email etc.). But with this new function, this "going-back-to-the-first-mistake" feature doesnt work, of course, because the validate() function sees it all good. I already added a rule for another form (about pictures upload) and it goes like this: $("#commentForm").validate({ rules: { foto34: { required: true, accept: "jpg|png|gif" } } }); Now my question is, how can i add the special validation function as a rule of the whole validation process ? Here is the page to understand it better: link text and the special field is the first one: CPF. Hope i was clear explaining my problem. Thanks in advance. kevin

  • How to convince someone, that reading programming related books(blogs, so..) is important? [closed]

    - by hgulyan
    Dear all, please, help me to convince, that no matter what you're doing, you need to read some stuff, try to learn something new. They say, that they don't want to sit in front of computer in the end of a day and they don't have opportunity to read in working hours, or they're too tired for doing something. Have you faced this kind of situation? What did you do? What if you want to help them? What methodology you'd suggest? How to open their eyes? EDIT I'm really concerned about this people. EDIT 2 Just to be clear, I'm not talking about one person or two. Some of them, just do their job good. Company doesn't motivate them to learn something. They're not bad people, not bad developers, they just need something or someone to help, show another view, but you can't just describe this new view or say smth like "You need to learn!" and that's it, you'll start to learn or you're not a good programmer. I started to learn OOP, DB structure 6 years ago and I had someone who had guided me. He told me to learn Java and MySQL, gave me some manuals and API's. That's how I started. What if they don't have that kind person or something else?

  • Using custom coordinates with QGraphicsScene

    - by Rob
    I am experimenting with a WYSIWYG editor that allows a user to draw shapes on a page and the Qt graphics scene support seems perfect for this. However, instead of working in pixels I want all my QGraphicsItem objects to work in tenths of a millimetre but I don't know how to achieve this. For example: // Create a scene that is the size if an A4 page (2100 = 21cm, 2970 = 29.7cm) QGraphicsScene* scene = new QGraphicsScene(0, 0, 2100, 2970); // Add a rectangle located 1cm across, 1cm down, 5cm wide and 2cm high QGraphicsItem* item = scene->addRect(100, 100, 500, 200); ... QGraphicsView* view = new QGraphicsView(scene); setCentralWidget(view); Now, when I display the scene above I want the shapes to appear at correct size for the screen DPI. Is this simply a case of using QGraphicsView::scale or do I have to do something more complicated? Note that if I was using a custom QWidget instead then I would use QPainter::setWindow and QPainter::setViewport to create a custom mapping mode but I can't see how to do this using the graphics scene support.

  • Thread Message Loop Hangs in Delphi

    - by erikjw
    Hello all. I have a simple Delphi program that I'm working on, in which I am attempting to use threading to separate the functionality of the program from its GUI, and to keep the GUI responsive during more lengthy tasks, etc. Basically, I have a 'controller' TThread, and a 'view' TForm. The view knows the controller's handle, which it uses to send the controller messages via PostThreadMessage. I have had no problem in the past using this sort of model for forms which are not the main form, but for some reason, when I attempt to use this model for the main form, the message loop of the thread just quits. Here is my code for the threads message loop: procedure TController.Execute; var Msg : TMsg; begin while not Terminated do begin if (Integer(GetMessage(Msg, hwnd(0), 0, 0)) = -1) then begin Synchronize(Terminate); end; TranslateMessage(Msg); DispatchMessage(Msg); case Msg.message of // ...call different methods based on message end; end; To set up the controller, I do this: Controller := TController.Create(true); // Create suspended Controller.FreeOnTerminate := True; Controller.Resume; For processing the main form's messages, I have tried using both Application.Run and the following loop (immediately after Controller.Resume) while not Application.Terminated do begin Application.ProcessMessages; end; I've run stuck here - any help would be greatly appreciated.

  • Why trigger fired only once when running on a JQuery Object?

  • Algorithm To Select Most Popular Places from Database

    - by Russell C.
    We have a website that contains a database of places. For each place our users are able to take one of the follow actions which we record: VIEW - View it's profile RATING - Rate it on a scale of 1-5 stars REVIEW - Review it COMPLETED - Mark that they've been there WISH LIST - Mark that they want to go there FAVORITE - Mark that it's one of their favorites In our database table of places each place contains a count of the number of times each action above was taken as well as the average rating given by users. views ratings avg_rating completed wishlist favorite What we want to be able to do is generate lists of the top places using the above information. Ideally, we would want to be able to generate this list using a relatively simple SQL query without needing to do any legwork to calculate additional fields or stack rank places against one another. That being said, since we only have about 50,000 places we could run a nightly cron job to calculate some fields such as rankings on different categories if it would make a meaningful difference in the overall results of our top places. I'd appreciate if you could make some suggestions on how we should think about bubbling the best places to the top, which criteria we should weight more heavily, and given that information - suggest what the MySQL query would need to look like in order to select the top 10 places. One thing to note is that at this time we are less concerned with the recency of a place being popular - meaning that looking at the aggregate information is fine and that more recent data doesn't need to be weighted more heavily. Thanks in advance for your help & advice!

  • JavaScript: window.opener.location.href question

    - by vastbeyond
    I need to make a little JS app to scroll automatically through a list of URLs. I've chosen to have the functionality in a pop-up, for various reasons. The syntax to change the opening window's URL is: window.opener.location.href = "http://www.example.com"; This works fine with one URL, but if two statements are called, only one is executed. I experimented with an alert statement between two of the above statements, and the alert event made the second statement function properly: window.opener.location.href = "http://www.example1.com"; alert("hello world"); window.opener.location.href = "http://www.example2.com"; Question is: does anyone know how to get the first and second window.opener statements to work, without the intervening alert();? Also, how can I add a pause between the two statements, so that the second executes a couple of seconds after the first? Thanks so much!

  • identifying id of listitem for contextmenu

    I have a View that extends Activity. A ListView will display a number of listitems.

Everything works ok, until the database is deleted, and i am trying to do rake db:migrate. rake db:migrate fails saying that cannot find 'product' table. inside init.rb = Product.populate_db The solution i came up is: I took out init.rb do rake db:migrate put back init.rb run the server.

Currently I have been able to detect the current colour (for instance a light blue) and set that colour in the ColorDialog (Colour swatches are correct and RGB values are correct). What I would like to do is enable the user to click on the "Add to Custom Colors" to save the colour. Problem is, it sets the first square in the custom colours area (which happens to already be filled in with another custom colour), rather than finding the next square that is white and set it there instead. Is this possible? If the user selects a new custom colour square when they first load the ColorDialog, the current colour (light blue) disappears and the colour swatches and RGB values are set as white. Thanks
