  • C# Windows Service XML

    - by Goober
    Scenario I have a windows service written in C# that performs some processing based on parsing an XML file and use that data to carry out various tasks. The service also does various bits of logging - which uses settings from an APP.Config file. The Problem When the service is compiled, installed and run, the XML file seems to disappear. I'm getting the impression that it is just ignored or something like that. So far I've tried using TWO App.Config files, one named App.Config that contains settings for the service, and the other called MyService.exe.config that contains all of the data that was used in the XML file (the idea being that I can parse the XML from a config file that actually gets compiled and appears in my installation directory. However When I do this, all that happens is that ONE config file appears (with the name MyService.exe.config), but it contains the contents of the App.Config file and not the XML data that I want to parse. What I need All I want is to have a config file for my settings, and an XML file for my data. Question Is this possible? I know the application works as it was originally built as a console application that ran fine. Other The application has to be designed this way (as in, I need my data stored as XML, and my settings stored in a config file). Thoughts If I could somehow combine the contents of the two files into ONE config file, that would be one way of solving the problem. However, I have tried this and of course I get a "Type Initialisation Exception", as the config file cannot interprate the XML data (probably because the tags are custom and do not form any part of the config schema - or something like that). Ideas Please could someone explain to me if it is possible for me to have an XML file AND a config file that will actually be compiled and stored in my installation directory for the service when it is run? CODE Custom XML/Data Config File <?xml version="1.0" encoding="utf-8" ?> <configuration> <servers> <SV066930> <add name="Name" value = "SV066930" /> <processes> <SimonTest1> <add name="ProcessName" value="notepad.exe" /> <add name="CommandLine" value="C:\\WINDOWS\\system32\\notepad.exe C:\\WINDOWS\\Profiles\\TA2TOF1\\Desktop\\SimonTest1.txt" /> </SimonTest1> </processes> </SV066930> </servers> </configuration> APP.Config Settings File <?xml version="1.0" encoding="utf-8" ?> <configuration> <configSections> <section name="dataConfiguration" type="Microsoft.Practices.EnterpriseLibrary.Data.Configuration.DatabaseSettings, Microsoft.Practices.EnterpriseLibrary.Data, Version=4.0.0.0, Culture=neutral, PublicKeyToken=xxxxxxxxxxx" /> </configSections> <connectionStrings> <add name="DB" connectionString="Data Source=etc......" /> </connectionStrings> </configuration> Help greatly appreciated.

  • ColdFusion blank page in IE7 on refresh?

    - by richardtallent
    I'm new to ColdFusion, have a very basic problem that's really slowing me down. I'm making edits in a text editor and refreshing the page in web browsers for testing. Standard web dev stuff, no browser-sniffing, redirection, or other weirdness, and no proxies involved. When I refresh the page in Chrome or Firefox, everything works fine, but when I refresh in IE7, I get a blank page. View Source shows me: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"> <HTML><HEAD> <META http-equiv=Content-Type content="text/html; charset=utf-8"></HEAD> <BODY></BODY></HTML> That's it. While I am rendering to the transitional DTD, the real head contains a title, etc. My development server is CF 9, production is 8. This problem has been happening in both. Seems it may only be happening on pages that are the the result of a POST action. I've never experienced this in ASP.NET (my usual development environment) using the same browsers.

  • Setting CommandTarget to selected control in a TabControl

    - by Bart
    I have a WPF window with a few buttons and a tabcontrol having a tab for each 'document' the user is working on. The tabcontrol uses a DataTemplate to render the data in ItemSource of the tabcontrol. The question: If one of the buttons is clicked, the command should be executed on the control rendering the document in the active tab, but I've no idea what I should set CommandTarget to. I tried {Binding ElementName=nameOfControlInDataTemplate} but that obviously doesn't work. I tried to make my problem a bit more abstract with the following code (no ItemSource and Document objects, but the idea is still the same). <Button Command="ApplicationCommands.Save" CommandTarget="{Binding ElementName=nestedControl}">Save</Button> <TabControl x:Name="tabControl"> <TabControl.Items> <TabItem Header="Header1">Item 1</TabItem> <TabItem Header="Header2">Item 2</TabItem> <TabItem Header="Header3">Item 3</TabItem> </TabControl.Items> <TabControl.ContentTemplate> <DataTemplate> <CommandTest:NestedControl Name="nestedControl"/> </DataTemplate> </TabControl.ContentTemplate> </TabControl> I tested the code by replacing the complete tabcontrol with only one single NestedControl, and then the command button just works. To be complete, here is the code of NestedControl: <UserControl x:Class="CommandTest.NestedControl" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"> <Grid> <Label x:Name="label" Content="Not saved"/> </Grid> </UserControl> And code behind: public partial class NestedControl : UserControl { public NestedControl() { CommandBindings.Add(new CommandBinding(ApplicationCommands.Save, CommandBinding_Executed)); InitializeComponent(); } private void CommandBinding_Executed(object sender, ExecutedRoutedEventArgs e) { label.Content = "Saved"; } }

  • Ajax -- re-load div on success.

    - by RPM
    I am trying to accomplish a "re-load." More specifically, I need to be able to refresh a portion of my page as a result of another successful ajax call. Moreover, I load my portion of the page via ajax which obtains it's content from an ajax post. The result is my content being displayed inside my portion precisely. I need this portion of the page refreshed after a successful ajax post. Here is some of the code: /* Ajax-- this part is loaded automatically, and I need it reloaded upon success of another ajax post. This data comes from the outcome of my other ajax function. */ $('#newCo').load('click', function() { $.ajax({ url: 'index.php?dkd432k=uBus/310/Indeed', dataType: 'json', success: function(json) { if (json['newCompare']) { $('#newCo .newResults').html(json['newCompare']); } } }); }); The next portion of code is responsible for posting the data of which I obtain in this above ajax function. function ZgHiapud (ofWhich) { $.ajax({ url: 'index.php?dkd432k=uBus/310/update', type: 'post', data: 'product_id=' + product_id, dataType: 'json', success: function(json) { $('.success, .warning, .attention, .information').remove(); if (json['success']) { $('.attention').fadeIn('slow'); $('#compare_total').html(json['total']); $('html, body').animate({ scrollTop: 0 }, 'slow'); } } }); } In the end, I need to obtain the data that I send to the server immediately upon success of the second ajax call. This data that is sent via the second ajax call needs to fire the first ajax call upon success.

  • How to run some code only once in view

    - by Freewind
    I have a partial view called '_comment.erb', and it may be called by parent many times(e.g. in a loop). The '_comment.erb' looks like: <script> function aaa() {} </script> <%= comment.content %> <%=link_to_function 'Do', 'aaa()' %> You can see if the '_comment.erb' be called many times, that the javascript function 'aaa' will be re-defined many times. I hope it can be define only once, but I don't want to move it to parent view. I hope there is a method, say 'run_once', and I can use it like this: <%= run_once do %> <script> function aaa() {} </script> <% end %> <%= comment.content %> <%=link_to_function 'Do', 'aaa()' %> No matter how many time I call the '_comment.erb', the code inside 'run_once' will be run only once. What shall I do?

  • Automatically grow document view of NSScrollView using auto layout?

    - by Monolo
    Is there a simple way to get an NSScrollView to adapt to its document view changing size when using autolayout (the Lion feature)? I have tried to call both setNeedsUpdateConstraints: and setNeedsLayout: on the document view, the clip view and the scroll view, without any results. fittingSize of the document view reports the correct size. An NSPopover in conjunction with an NSViewController handles this nicely, with the popover growing and shrinking as needed, and I was hoping to get a similar simple and robust behaviour with the scroll view. I have checked the documentation for scroll views, but they don't seem to be updated to use autolayout. Edited to clarify: The problem I experience is that the document view, which holds subviews, is not re-sized when the subviews change their size, even if they call invalidateIntrinsicContentSize. The contents of the document view are hence clipped to the original size of the document view as they grow. The document view is created in a nib and set as the scroll view's document view in an awakeFromBib method. What I hoped to obtain was that the document view frame would automatically be adjusted to when its fittingSize changes, and the scrollbars updated accordingly. NSPopover does something similar - provided that the subviews of the content controller's view have the constraints set right and various content hugging values are high enough (higher than the hidden popover window's hight constraint priority, for one).

  • UIView: how to do non-destructive drawing?

    - by Caffeine Coma
    My original question: I'm creating a simple drawing application and need to be able to draw over existing, previously drawn content in my drawRect. What is the proper way to draw on top of existing content without entirely replacing it? Based on answers received here and elsewhere, here is the deal. You should be prepared to redraw the entire rectangle whenever drawRect is called. You cannot prevent the contents from being erased by doing the following: [self setClearsContextBeforeDrawing: NO]; This is merely a hint to the graphics engine that there is no point in having it pre-clear the view for you, since you will likely need to re-draw the whole area anyway. It may prevent your view from being automatically erased, but you cannot depend on it. To draw on top of your view without erasing, do your drawing to an off-screen bitmap context (which is never cleared by the system.) Then in your drawRect, copy from this off-screen buffer to the view. Example: - (id) initWithCoder: (NSCoder*) coder { if (self = [super initWithCoder: coder]) { self.backgroundColor = [UIColor clearColor]; CGSize size = self.frame.size; drawingContext = [self createDrawingBufferContext: size]; } return self; } - (CGContextRef) createOffscreenContext: (CGSize) size { CGColorSpaceRef colorSpace = CGColorSpaceCreateDeviceRGB(); CGContextRef context = CGBitmapContextCreate(NULL, size.width, size.height, 8, size.width*4, colorSpace, kCGImageAlphaPremultipliedLast); CGColorSpaceRelease(colorSpace); CGContextTranslateCTM(context, 0, size.height); CGContextScaleCTM(context, 1.0, -1.0); return context; } - (void)drawRect:(CGRect) rect { UIGraphicsPushContext(drawingContext); CGImageRef cgImage = CGBitmapContextCreateImage(drawingContext); UIImage *uiImage = [[UIImage alloc] initWithCGImage:cgImage]; UIGraphicsPopContext(); CGImageRelease(cgImage); [uiImage drawInRect: rect]; [uiImage release]; } TODO: can anyone optimize the drawRect so that only the (usually tiny) modified rectangle region is used for the copy?

  • Why Spark viewengine renders unnecessary (or unexpected) quotes?

    - by Arnis L.
    If i add pageBaseType="Spark.Web.Mvc.SparkView" in my web.config (necessary to fix intellisense), somehow it does not render links (probably not only) correctly anymore. This is how it's supposed to look like (and does, if page base type is not specified)= This is how it looks when base type is specified= Chrome source viewer shows identical page source code for both cases= <body> <div class="content"> <div class="navigation"> <a href="/Employee/List">Employees</a> <a href="/Product/List">Products</a> <a href="/Store/List">Stores</a> <div class="navigation_title"> Navigation</div> </div> <div class="main"> <div class="content"> <h2>Employees</h2>Nothing found... &lt;a href=&quot;/Employee/Create&quot;&gt;Create&lt;/a&gt; </div> </div> </div> </body> Developer tools does not= So - why my link gets htmlencoded (if that's what happens)? If it's default behavior, then how to render raw html? Using latest Spark version, rebuilt with Asp.Net Mvc2 RC assemblies.

  • Prompt User before browser close?

    - by JM4
    We have an administrative portal that our teachers constantly forget to download their latest PDF instructions before logging out and/or closing the browser window. I have looked around but can't find what I'm looking for. I want to accomplish the following goals: Goal 1 Before a user can close the browser window, they are prompted "Did you remember to download your form?" with two options, yes/no. If yes, close, if no, return to page. Goal 2 Before a user can click the 'logout' button, they are prompted with the same as above. My first pass at the very basic code (which does not work for browser close) is: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>Untitled Document</title> <script type="text/javascript"> function init() { if(window.addEventListener) { window.addEventListener("beforeunload", unloadMess, false); } else if(window.onbeforeunload) { window.onbeforeunload = unloadMess; }; } function unloadMess() { var User_Message = "[Your user message here]" return User_Message; } </script> </head> <body onload="init();"> hello this is my site </body> </html> anybody ever come across a good solution?

  • Troubleshooting FORM POST problems

    - by brettr
    I'm using the following code to submit to a WCF service. I keep getting an error that the key is invalid. I have a webpage on the same server that I submit the same data (but different key) using a FORM POST. It works fine that way. I put the URL below all in a URL (including valid key from server webpage) and get the key is invalid error. I'm thinking the data I'm submitting through the iPhone isn't really going across as a FORM POST but rather as a URL. Is there anything I may be doing wrong in the following code or any other suggestions? NSString *stringForURL = @"https://abc.com/someservice.aspx"; NSURL *URL=[[NSURL alloc] initWithString:stringForURL]; NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:URL]; NSString *request_body = [NSString stringWithFormat:@"prop1=value1&key=%@", [@"r2xHEuzgDTQEWA5Xe6+k9BSVrgsMX2mWQBW/39nqT4s=" stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]]; NSData *postData = [request_body dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES]; NSString *postLength = [NSString stringWithFormat:@"%d", [postData length]]; [request setValue:postLength forHTTPHeaderField:@"Content-Length"]; [request setHTTPMethod:@"POST"]; [request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"]; [request setHTTPBody:postData]; NSURLConnection *connection = [[NSURLConnection alloc] initWithRequest:request delegate:self]; [NSThread sleepForTimeInterval:1]; self.receivedData = [[NSMutableData data] retain];

  • Issue Implementing Colorbox Correctly in IE (all versions)

    - by Andrew
    I've been pulling my hair out (and going way over allotted hours) to try and figure out why Colorbox isn't working properly on the following page: http://www.fiberforge.com I've set up a Colorbox test link on the very bottom right that says "Web Design By All Web Cafe", which should open up a small logo image. In Firefox, Safari, etc the modal behaves as it should, opening center center above all of the existing on-page content. In IE, not only is the modal not centered, but it appears as though it's not obeying absolute positioning and pushing all of the existing on-page content down below. Add to that the fact that it's not opening to the correct size and creating scrollbars next to the modal image, and we have ourselves one ugly modal. The scrollbars I can live with (by just resizing the min-height of the modal), but I can't figure out why it won't center. Let me say that I did not code this site initially and it was completed quite a few years ago, so there are quite probably numerous CSS hacks to get things to display properly, any number of which may be causing this problem. By contrast, Thickbox is also set up on this site (if you click on the "Play Video" callout in the dark blue area) and behaves correctly, though suffers from some weird sizing/padding issues, hence the desire to replace it with something a bit more modern and extensible. I can verify that there is no conflict having both of these modal scripts/CSS files concurrently as the problem still occurs with Colorbox even when Thickbox is removed entirely. Any thoughts or suggestions would be greatly appreciated.

  • How do I create self-relationships in polymorphic inheritance in Elixir and Pylons?

    - by Turukawa
    I am new to programming and am following the example in the Pylons documentation on creating a Wiki. The database I want to link to the wiki was created with Elixir so I rewrote the Wiki database schema and have continued from there. In the wiki there is a requirement for a Navigation table which is inherited by Pages and Sections. A section can have many pages, while a page can only have one section. In addition, each sibling node can be chain-referenced to each other. So: Nav has "section" (OneToMany) and "before" (OneToOne - to reference preceeding node) Page has "section" (ManyToOne - many pages in one section) and inherits "before" Section inherits all from Nav The code I've written looks like this: class Nav(Entity): using_options(inheritance='multi') name = Field(Unicode(30), default=u'Untitled Node') path = Field(Unicode(255), default=u'') section = OneToMany('Page', inverse='section') after = OneToOne('Nav', inverse='before') before = OneToMany('Nav', inverse='after') class Page(Nav): using_options(inheritance='multi') content = Field(UnicodeText, nullable=False) posted = Field(DateTime, default=now()) title = Field(Unicode(255), default=u'Untitled Page') heading = Field(Unicode(255)) tags = ManyToMany('Tag') comments = OneToMany('Comment') section = ManyToOne('Nav', inverse='section') class Section(Nav): using_options(inheritance='multi') Errors received on this: sqlalchemy.exc.OperationalError: (OperationalError) table nav has no column named aftr_id u'INSERT INTO nav (name, path, aftr_id, row_type) VALUES (?, ?, ?, ?)' I've also tried: before = ManyToMany('Nav', inverse='before') on Nav in the hopes this might break the problem, but also not. The original SQLAlchemy code from the tutorial for these declarations is as follows: nav_table = schema.Table('nav', meta.metadata, schema.Column('id', types.Integer(), schema.Sequence('nav_id_seq', optional=True), primary_key=True), schema.Column('name', types.Unicode(255), default=u'Untitled Node'), schema.Column('path', types.Unicode(255), default=u''), schema.Column('section', types.Integer(), schema.ForeignKey('nav.id')), schema.Column('before', types.Integer(), default=None), schema.Column('type', types.String(30), nullable=False) ) page_table = schema.Table('page', meta.metadata, schema.Column('id', types.Integer, schema.ForeignKey('nav.id'), primary_key=True), schema.Column('content', types.Text(), nullable=False), schema.Column('posted', types.DateTime(), default=now), schema.Column('title', types.Unicode(255), default=u'Untitled Page'), schema.Column('heading', types.Unicode(255)), ) section_table = sa.Table('section', meta.metadata, schema.Column('id', types.Integer, schema.ForeignKey('nav.id'), primary_key=True), ) orm.mapper(Nav, nav_table, polymorphic_on=nav_table.c.type, polymorphic_identity='nav') orm.mapper(Section, section_table, inherits=Nav, polymorphic_identity='section') orm.mapper(Page, page_table, inherits=Nav, polymorphic_identity='page', properties={ 'comments':orm.relation(Comment, backref='page', cascade='all'), 'tags':orm.relation(Tag, secondary=pagetag_table) }) Any help is much appreciated.

It seems all the wait time on SQL Sever when this happens is given to SOS_SCHEDULER_YIELD. Here is the Stored Proc that causes the hang. I've added the "WITH (NOLOCK)" in an attempt to fix what seems to be a locking issue. ALTER PROCEDURE [dbo].[MostPopularRead] AS BEGIN SET NOCOUNT ON; SELECT c.ForeignId , ct.ContentSource as ContentSource , sum(ch.HitCount * hw.Weight) as Popularity , (sum(ch.HitCount * hw.Weight) * 100) / @Total as Percent , @Total as TotalHits from ContentHit ch WITH (NOLOCK) join [Content] c WITH (NOLOCK) on ch.ContentId = c.ContentId join HitWeight hw WITH (NOLOCK) on ch.HitWeightId = hw.HitWeightId join ContentType ct WITH (NOLOCK) on c.ContentTypeId = ct.ContentTypeId where ch.CreatedDate between @Then and @Now group by c.ForeignId , ct.ContentSource order by sum(ch.HitCount * hw.HitWeightMultiplier) desc END The stored proc reads from the table "ContentHit", which is a table that tracks when content on the site is clicked (it gets hit quite frequently - anything from 4 to 20 hits a minute). So its pretty clear that this table is the source of the problem. There is a stored proc that is called to add hit tracks to the ContentHit table, its pretty trivial, it just builds up a string from the params passed in, which involves a few selects from some lookup tables, followed by the main insert: BEGIN TRAN insert into [ContentHit] (ContentId, HitCount, HitWeightId, ContentHitComment) values (@ContentId, isnull(@HitCount,1), isnull(@HitWeightId,1), @ContentHitComment) COMMIT TRAN The ContentHit table has a clustered index on its ID column, and I've added another index on CreatedDate since that is used in the select. When I profile the issue, I see the Stored proc executes for exactly 30 seconds, then the SQL timeout exception occurs. If it makes a difference the web application using it is ASP.NET, and I'm using Subsonic (3) to execute these stored procs. Can someone please advise how best I can solve this problem? I don't care about reading dirty data... Thanks

  • jQuery date picker not persistant after AJAX

    - by ILMV
    So I'm using the jQuery date picker, and it works well. I am using AJAX to go and get some content, obviously when this new content is applied the bind is lost, I learnt about this last week and discovered about the .live() method. But how do I apply that to my date picker? Because this isn't an event therefore .live() won't be able to help... right? This is the code I'm using to bind the date picker to my input: $(".datefield").datepicker({showAnim:'fadeIn',dateFormat:'dd/mm/yy',changeMonth:true,changeYear:true}); I do not want to call this metho everytime my AJAX fires, as I want to keep that as generic as possible. Cheers :-) EDIT As @nick requested, below is my wrapper function got the ajax() method: var ajax_count = 0; function getElementContents(options) { if(options.type===null) { options.type="GET"; } if(options.data===null) { options.data={}; } if(options.url===null) { options.url='/'; } if(options.cache===null) { options.cace=false; } if(options.highlight===null || options.highlight===true) { options.highlight=true; } else { options.highlight=false; } $.ajax({ type: options.type, url: options.url, data: options.data, beforeSend: function() { /* if this is the first ajax call, block the screen */ if(++ajax_count==1) { $.blockUI({message:'Loading data, please wait'}); } }, success: function(responseText) { /* we want to perform different methods of assignment depending on the element type */ if($(options.target).is("input")) { $(options.target).val(responseText); } else { $(options.target).html(responseText); } /* fire change, fire highlight effect... only id highlight==true */ if(options.highlight===true) { $(options.target).trigger("change").effect("highlight",{},2000); } }, complete: function () { /* if all ajax requests have completed, unblock screen */ if(--ajax_count===0) { $.unblockUI(); } }, cache: options.cache, dataType: "html" }); } What about this solution, I have a rules.js which include all my initial bindings with the elements, if I were to put these in a function, then call that function on the success callback of the ajax method, that way I wouldn't be repeating code... Hmmm, thoughts please :D

  • Simplepie - fetch feeds from database

    - by krike
    I want to fetch multiple feeds from the database and in so doing fetch all new content from those feeds it works but there is a problem and I have no idea what's causing it, this is the code: $feed_sql = mysqli_query($link, "SELECT feed from tutorial_feed WHERE approved=1"); $feeds = array(); $i = 0; while($feed_r = mysqli_fetch_object($feed_sql)): $feeds[$i] .= $feed_r->feed; $i++; endwhile; $feed = new SimplePie($feeds); $feed-handle_content_type(); foreach($feed-get_items(0, 100) as $item) : echo $item-get_permalink().""; endforeach; I first get Notice: Undefined offset: 0 in I:\wamp\www\cmstut\includes\cron.php on line 22 Notice: Undefined offset: 1 in I:\wamp\www\cmstut\includes\cron.php on line 22 Notice: Undefined offset: 2 in I:\wamp\www\cmstut\includes\cron.php on line 22 Notice: Undefined offset: 3 in I:\wamp\www\cmstut\includes\cron.php on line 22 Notice: Undefined offset: 4 in I:\wamp\www\cmstut\includes\cron.php on line 22 Notice: Undefined offset: 5 in I:\wamp\www\cmstut\includes\cron.php on line 22 Notice: Undefined offset: 6 in I:\wamp\www\cmstut\includes\cron.php on line 22 Notice: Undefined offset: 7 in I:\wamp\www\cmstut\includes\cron.php on line 22 Notice: Undefined offset: 8 in I:\wamp\www\cmstut\includes\cron.php on line 22 Notice: Undefined offset: 9 in I:\wamp\www\cmstut\includes\cron.php on line 22 Notice: Undefined offset: 10 in I:\wamp\www\cmstut\includes\cron.php on line 22 and then it will start printing the permalinks to the new content based on the imported feeds, I know undefined offset means it does not exist but I don't get it, any help would be appreciated

  • Use QuickCheck by generating primes

    - by Dan
    Background For fun, I'm trying to write a property for quick-check that can test the basic idea behind cryptography with RSA. Choose two distinct primes, p and q. Let N = p*q e is some number relatively prime to (p-1)(q-1) (in practice, e is usually 3 for fast encoding) d is the modular inverse of e modulo (p-1)(q-1) For all x such that 1 < x < N, it is always true that (x^e)^d = x modulo N In other words, x is the "message", raising it to the eth power mod N is the act of "encoding" the message, and raising the encoded message to the dth power mod N is the act of "decoding" it. (The property is also trivially true for x = 1, a case which is its own encryption) Code Here are the methods I have coded up so far: import Test.QuickCheck -- modular exponentiation modExp :: Integral a => a -> a -> a -> a modExp y z n = modExp' (y `mod` n) z `mod` n where modExp' y z | z == 0 = 1 | even z = modExp (y*y) (z `div` 2) n | odd z = (modExp (y*y) (z `div` 2) n) * y -- relatively prime rPrime :: Integral a => a -> a -> Bool rPrime a b = gcd a b == 1 -- multiplicative inverse (modular) mInverse :: Integral a => a -> a -> a mInverse 1 _ = 1 mInverse x y = (n * y + 1) `div` x where n = x - mInverse (y `mod` x) x -- just a quick way to test for primality n `divides` x = x `mod` n == 0 primes = 2:filter isPrime [3..] isPrime x = null . filter (`divides` x) $ takeWhile (\y -> y*y <= x) primes -- the property prop_rsa (p,q,x) = isPrime p && isPrime q && p /= q && x > 1 && x < n && rPrime e t ==> x == (x `powModN` e) `powModN` d where e = 3 n = p*q t = (p-1)*(q-1) d = mInverse e t a `powModN` b = modExp a b n (Thanks, google and random blog, for the implementation of modular multiplicative inverse) Question The problem should be obvious: there are way too many conditions on the property to make it at all usable. Trying to invoke quickCheck prop_rsa in ghci made my terminal hang. So I've poked around the QuickCheck manual a bit, and it says: Properties may take the form forAll <generator> $ \<pattern> -> <property> How do I make a <generator> for prime numbers? Or with the other constraints, so that quickCheck doesn't have to sift through a bunch of failed conditions? Any other general advice (especially regarding QuickCheck) is welcome.

  • Render action return View(); form problem

    - by Roger Rogers
    I'm new to MVC, so please bear with me. :-) I've got a strongly typed "Story" View. This View (story) can have Comments. I've created two Views (not partials) for my Comments controller "ListStoryComments" and "CreateStoryComment", which do what their names imply. These Views are included in the Story View using RenderAction, e.g.: <!-- List comments --> <h2>All Comments</h2> <% Html.RenderAction("ListStoryComments", "Comments", new { id = Model.Story.Id }); %> <!-- Create new comment --> <% Html.RenderAction("CreateStoryComment", "Comments", new { id = Model.Story.Id }); %> (I pass in the Story id in order to list related comments). All works as I hoped, except, when I post a new comment using the form, it returns the current (parent) View, but the Comments form field is still showing the last content I typed in and the ListStoryComments View isn’t updated to show the new story. Basically, the page is being loaded from cache, as if I had pressed the browser’s back button. If I press f5 it will try to repost the form. If I reload the page manually (reenter the URL in the browser's address bar), and then press f5, I will see my new content and the empty form field, which is my desired result. For completeness, my CreateStoryComment action looks like this: [HttpPost] public ActionResult CreateStoryComment([Bind(Exclude = "Id, Timestamp, ByUserId, ForUserId")]Comment commentToCreate) { try { commentToCreate.ByUserId = userGuid; commentToCreate.ForUserId = userGuid; commentToCreate.StoryId = 2; // hard-coded for testing _repository.CreateComment(commentToCreate); return View(); } catch { return View(); } }

  • forcing a child component to resize itself larger than its container

    - by Josh
    I am creating a component that displays a variable amount of "gauges" (square tiles of content if you will), that is laid out like so: <HDividedBox id="container"> <VBox id="myComponent"> <HBox id="header"> ...header content... </HBox> <Tile id="body"> ...gauges are added to the body... </Tile> </Vbox> </HDividedBox> The body Tile has a horizontal direction. When I drag the HDividedBox to make myComponent smaller, the body component will get smaller as well, and eventually if there are too many gauges to fit horizontally, they will be bumped to the next row, and thus the smaller I make myComponent, the number of vertically stacked gauges grows. This is all well and good. The problem is, no matter what combination of settings I use, I absolutely cannot get the body (a Tile) to size itself beyond the size of myComponent, which would ideally cause myComponent to scroll vertically. Even setting the maxHeight of the body to some huge value, it will never size itself larger than it's container. Any ideas on how to accomplish this? Thanks

  • Android - Correspondence between ImageView coordinates and Bitmap Pixels

    - by Matteo
    In my application I want the user to be able to select some content of an Image contained inside an ImageView. To select the content I subclassed the ImageView class making it implement the OnTouchListener so to draw over it a rectangle with borders decided by the user. Here is an example of the result of the drawing (to have an idea you can think of it as when you click with the mouse on your desktop and drag the mouse): Now I need to determine which pixels of the Bitmap image correspond to the selected part. It's kind of easy to determine which are the points of the ImageView belonging to the rectangle, but I don't know how to get the correspondent pixels, since the ImageView has a different aspect ratio than the original image. I followed the approach described especially here, but also here, but am not fully satisfied because in my opinion the correspondence made is 1 on 1 between pixels and points on the ImageView and does not give me all the correspondent pixels on the original image to the selected area. Calling hoveredRect the rectangle on the ImageView the points inside of it are: class Point { float x, y; @Override public String toString() { return x + ", " + y; } } Vector<Point> pointsInRect = new Vector<Point>(); for( int x = hoveredRect.left; x <= hoveredRect.right; x++ ){ for( int y = hoveredRect.top; y <= hoveredRect.bottom; y++ ){ Point pointInRect = new Point(); pointInRect.x = x; pointInRect.y = y; pointsInRect.add(pointInRect); } } How can I obtain a Vector<Pixels> pixelsInImage containing the correspondent pixels?
