  • Windows Phone app: Binding data in a UserControl which is contained in a ListBox

    - by Alexandros Dafkos
    I have an "AddressListBox" ListBox that contains "AddressDetails" UserControl items, as shown in the .xaml file extract below. The Addresses collection is defined as ObservableCollection< Address Addresses and Street, Number, PostCode, City are properties of the Address class. The binding fails, when I use the "{Binding property}" syntax shown below. The binding succeeds, when I use the "dummy" strings in the commented-out code. I have also tried "{Binding Path=property}" syntax without success. Can you suggest what syntax I should use for binding the data in the user controls? <ListBox x:Name="AddressListBox" DataContext="{StaticResource dataSettings}" ItemsSource="{Binding Path=Addresses, Mode=TwoWay}"> <ListBox.ItemTemplate> <DataTemplate> <!-- <usercontrols:AddressDetails AddressRoad="dummy" AddressNumber="dummy2" AddressPostCode="dummy3" AddressCity="dummy4"> </usercontrols:AddressDetails> --> <usercontrols:AddressDetails AddressRoad="{Binding Street}" AddressNumber="{Binding Number}" AddressPostCode="{Binding PostCode}" AddressCity="{Binding City}"> </usercontrols:AddressDetails> </DataTemplate> </ListBox.ItemTemplate> </ListBox>

  • C# - Removing event handlers - FormClosing event or Dispose() method

    - by Andy
    Suppose I have a form opened via the .ShowDialog() method. At some point I attach some event handlers to some controls on the form. e.g. // Attach radio button event handlers. this.rbLevel1.Click += new EventHandler(this.RadioButton_CheckedChanged); this.rbLevel2.Click += new EventHandler(this.RadioButton_CheckedChanged); this.rbLevel3.Click += new EventHandler(this.RadioButton_CheckedChanged); When the form closes, I need to remove these handlers, right? At present, I am doing this when the FormClosing event is fired. e.g. private void Foo_FormClosing(object sender, FormClosingEventArgs e) { // Detach radio button event handlers. this.rbLevel1.Click -= new EventHandler(this.RadioButton_CheckedChanged); this.rbLevel2.Click -= new EventHandler(this.RadioButton_CheckedChanged); this.rbLevel3.Click -= new EventHandler(this.RadioButton_CheckedChanged); } However, I have seen some examples where handlers are removed in the Dispose() method. Is there a 'best-practice' way of doing this? (Using C#, Winforms, .NET 2.0) Thanks.

  • Canonical resource for forms-based design in ASP.NET MVC?

    - by Robert Harvey
    Is there a resource on the web that describes various form scenarios in ASP.NET MVC, and gives example solutions within a sensible, consistent design philosophy? Examples of such scenarios might be: One-to-many forms, like invoice data-entry forms. Foreign-table forms such as Add New User in a form that requires specifying a user Forms that require dynamic interaction, using Ajax or JSON. Popup forms Forms requiring multiple data records to be input, without postbacks. Note that there is considerable conceptual and technological overlap among these example scenarios. I am aware that there is a vast patchwork quilt of available technologies and examples out there that provide partial solutions and pieces of solutions, such as jQuery Ajax, CSS, and so forth. But I would like guidance in using these technologies in more effective and consistent ways. I am not considering web forms integration with an ASP.NET MVC application; I would still like my applications to be pure MVC. Nor am I, at the moment, considering a paid solution like Telerik. But I would like to know if someone has already done some of the work combining these technologies into a consistent, cohesive whole, that follows a sensible design philosophy. (an open source framework, perhaps?)

  • jquery ready function: script not detecting a function

    - by deostroll
    There is a web page with place holder (a normal div). Via ajax calls I am loading a <form> and a <script> into the place holder. The script contains necessary javascript to initialize the form (i.e. for e.g. disable the controls so as to make form read-only, etc). Here is a piece of code I have; it works, but the commented part doesn't work. Because the script engine cannot find the object tristate_DisableControl which is a function in one of those scripts I call via ajax. $(document).ready(function() { // $('#site_preferences_content div').each(function() { // if (typeof (window.tristate_DisableControl) == 'undefined') { // if (typeof (window.console) != 'undefnied') // console.log((new Date()).toTimeString() + ' not logable'); // pausecomp(1000); // } // else // tristate_DisableControl(this); // }); //end $('#site_prefrences_content div').each() setTimeout(function() { $('#site_preferences_content div').each(function() { tristate_DisableControl(this); }) }, 1000); }); I thought by the time $(document).ready() executes the DOM will be properly loaded...

  • Centering a div block without the width

    - by Vinicius
    Hi, I have a problem when I try to center the div block "products" because I don't know in advance the div width. Anybody have a solution? Update: The problem I have is I don't know how many products I'll display, I can have 1, 2 or 3 products, I can center them if it was a fixed number as I'd know the width of the parent div, I just don't know how to do it when the content is dynamic. <style> .product_container { text-align: center; height: 150px; } .products { height: 140px; text-align: center; margin: 0 auto; clear: ccc both; } .price { margin: 6px 2px; width: 137px; color: #666; font-size: 14pt; font-style: normal; border: 1px solid #CCC; background-color: #EFEFEF; } </style> <div class="product_container"> <div class="products" id="products"> <div id="product_15"> <img src="/images/ecommerce/card_default.png"> <div class="price">R$ 0,01</div> </div> <div id="product_15"> <img src="/images/ecommerce/card_default.png"> <div class="price">R$ 0,01</div> </div> <div id="product_15"> <img src="/images/ecommerce/card_default.png"> <div class="price">R$ 0,01</div> </div> </div> </div>

  • Looping HTML5 audio on the iPhone

    - by Peeps
    I'm trying to make a HTML5 webapp that simply plays a sound over and over and over again, on my iPhone. I don't know any Obj-C to do it natively. What I have works fine, but the sound only plays once: <!DOCTYPE html> <html> <head> <title>noisemaker!</title> <meta http-equiv="content-type" content="text/html; charset=utf-8" /> <meta name="viewport" content="maximum-scale=1, minimum-scale=1, width=device-width, user-scalable=no" /> <meta name="apple-mobile-web-app-capable" content="yes" /> </head> <body> <audio src="noise.mp3" autoplay controls loop></audio> </body> </html> Is there a way to either bypass the QuickTime audio screen and loop it in the webpage, or get the QuickTime audio screen to loop the sound?

  • Modelling Business Logic with NON-Techies

    - by cbmeeks
    The setup: Winform/ASP.NET MVC projects. Learning NHibernate SQL-Server driven apps I work with clients that have no idea how to model an application. That's what I'm for. However, we have lots of conflicts with validation, mis-understandings, etc. For example, the client will ask for an order entry screen. The screen should require a "product". That's fine and dandy. However, the client didn't know to tell me that the user can't order a product of "Class A" unless it's Tuesday. Or, they need a time entry screen. 2 days before it's rolled into production, they casually forgot to mention that certain activities are only valid for certain situations. These situations being a week of coding. That's of course, some crude examples (not by much!). But the problem is getting these non-technical clients to layout their business logic. They somehow didn't realize that the "Class A" problem would come up two weeks later, etc. I'm all for agile programming but is there an easy way to somehow make business logic like this extremely easy to implement and change on almost a daily basis? I of course am splitting the project into hopefully intelligent pieces, using NHibernate, etc. But making this BI logic so dynamic is really making it hard to project timelines, etc. Any suggestions? I know there will never be a perfect client (or a perfect provider) but how do you guys deal with the constant mis-understandings? Thanks.

  • How to Read some of the properties of the ItemSource when Laying out the Children?

    - by user275561
    Assume that I have the ItemSource bound and i am getting the data. Now what I want is this. The ItemSource will contain Data that tells where each button should be. For Example: The first Button could be at Left:200,Top:0, the Second could be Left:50 Top:20. </ItemsControl.Resources> <ItemsControl.ItemsPanel> <ItemsPanelTemplate> <Controls:MatrixCanvas /> </ItemsPanelTemplate> </ItemsControl.ItemsPanel> <ItemsControl.ItemTemplate> <DataTemplate> <item:CustomButton Height="{Binding btnSize}" Width="{Binding btnSize}" Style="{Binding bbColor,Converter={StaticResource ButtonStyleConverter}}" /> </DataTemplate> </ItemsControl.ItemTemplate> </ItemsControl> protected override Size ArrangeOverride(Size finalSize) { foreach (var child in Children) { //The child } return base.ArrangeOverride(finalSize); } The Child however is not giving me access to the Item that I want. Is their a good solution for this? Am I going about this the wrong way? The reason I am doing it like this is because their can be buttons added dynamically, removed, some buttons will need to move around etc..

  • Trigger doesn't work

    - by Pasha
    Hello everyone, I have an user control, It is editable text block.

  • Searching a document for multiple terms in VBA?

    - by Tony
    I'm trying to create a macro to be used in Microsoft Word 2007 that will search a document for multiple keywords (string variables) located in an external Excel file (the reason for having it in an external file is that the terms will often be changed and updated). I've figured out how to search a document paragraph by paragraph for a single term and color every instance of that term, and I assumed that the proper method would be to use a dynamic array as the search term variable. The question is: how do I get the macro to create an array containing all the terms from an external file and search each paragraph for each and every term? This is what I have so far: Sub SearchForMultipleTerms() ' Dim SearchTerm As String 'declare search term SearchTerm = InputBox("What are you looking for?") 'prompt for term. this should be removed, as the terms should come from an external XLS file rather than user input. Selection.Find.ClearFormatting Selection.Find.Replacement.ClearFormatti… With Selection.Find .Text = SearchTerm 'find the term! .Forward = True .Wrap = wdFindStop .Format = False .MatchCase = False .MatchWholeWord = False .MatchWildcards = False .MatchSoundsLike = False .MatchAllWordForms = False End With While Selection.Find.Execute Selection.GoTo What:=wdGoToBookmark, Name:="\Para" 'select paragraph Selection.Font.Color = wdColorGray40 'color paragraph Selection.MoveDown Unit:=wdParagraph, Count:=1 'move to next paragraph Wend End Sub Thanks for looking!

  • iPhone static library Clang/LLVM error: non_lazy_symbol_pointers

    - by Bekenn
    After several hours of experimentation, I've managed to reduce the problem to the following example (C++): extern "C" void foo(); struct test { ~test() { } }; void doTest() { test t; // 1 foo(); // 2 } This is being compiled for iOS devices in XCode 4.2, using the provided Clang compiler (Apple LLVM compiler 3.0) and the iOS 5.0 SDK. The project is configured as a Cocoa Touch Static Library, and "Enable Linking With Shared Libraries" is set to No because I'm building an AIR native extension. The function foo is defined in another external library. (In my actual project, this would be any of the C API functions defined by Adobe for use in AIR native extensions.) When attempting to compile this code, I get back the error: FATAL:incompatible feature used: section type non_lazy_symbol_pointers (must specify "-dynamic" to be used) clang: error: assembler command failed with exit code 1 (use -v to see invocation) The error goes away if I comment out either of the lines marked 1 or 2 above, or if I change the build setting "Enable Linking With Shared Libraries" to Yes. (However, if I change the build setting, then I get multiple ld warning: unexpected srelocation type 9 warnings when linking the library into the final project, and the application crashes when running on the device.) The build error also goes away if I remove the destructor from test. So: Is this a bug in Clang? Am I missing some all-important and undocumented build setting? The interaction between an externally-provided function and a struct with a destructor is very peculiar, to say the least.

  • Will rel=canonical break site: queries ?

    - by Justin Grant
    Our company publishes our software product's documentation using a custom-built content management system using a dynamic URL namespace like this: http://ourproduct.com/documentation/version/pageid Where "version" is the version number to which the documentation applies, and "pageid" is a unique string which identifies that page in our back-end content management system. For example, if content (e.g. a page about configuration best practices) is unchanged from version 3.0 and 4.0 of our product, it'd be reachable by two different URLs: http://ourproduct.com/documentation/3.0/configuration-best-practices http://ourproduct.com/documentation/4.0/configuration-best-practices This URL scheme allows us to scope Google search results to see only documentaiton for a particular product version, like this: configuration site:ourproduct.com/documentation/4.0 But when the user is searching across all versions, we don't want Google to arbitrarily choose one of the URLs to show in results. Instead, we always want the latest version to show up. Hence our planned use of rel=canonical so we can proscriptively tell Google which URL we want to show up if multiple versions are being searched. (Users who do oddball things like searching 2 versions but not all of them are a corner case, so we don't care which version(s) show up in that case-- the primary use-cases we care about is searching one version or searching all versions) But what will happen to scoped searches if we do this? If my rel=canonical URL points to version 4.0, but my search is scoped to 3.0, will Google return a result? Even if you don't know the answer offhand, do you know a site which uses rel=canonical to redirect across folders in a URL namespace. If so, I could run a few Google searches and figure out the answer.

  • Managing/Storing complex application form

    - by mickyjtwin
    I am developing an online application form, which can be of two categories, either domestic/international. Each different type has commong questions, and also specific questions. They are approx 6 pages/steps of questions. The application form can also be saved at the end of each step, and can be completed at a later date. Some questions will vary depending on answers to previous questions, so there are some complex business rules. In terms of storage of results, would it be best to store the answers in and XML field in SQL? What would be the best way to reference a question to an answer. There is no need for the form to be dynamic in rendering questions etc. e.g. <Application id="123" type="Domestic"> <Answers> <EmailAddress>[email protected]</EmailAddress> <HomePhone>555-5555</HomePhone> <Suburb>MySuburb</Suburb> <Guardians> <Guardian type="Mother"> <FirstName>Mom</FirstName> </Guardian> </Guardians> <Answers> </Application>

  • Placement/Positioning/Alignment of UIScrollView w.r.t. length of Title NSString

    - by Shoaibi
    I have a scenario where i show stuff like: ----------------------------------- titleview (UITextView) ______________ tArea (UIScrollView) ttextview (UITextView) ----------------------------------- Now here is the condition: Length of titleview's text is dynamic, varies based on user input. Because of the condition I have trouble placing tArea e.g. UIScrollView on the screen, it either appears way too below than the titleview, or overlaps it. Previously what i did: Count the number of characters in titleview.text.length and divide them by 27 (e.g. characters in one line when using boldSystemFontOfSize:20) and multiply by 10 to get the starting X of tArea e.g. UIScrollView. But that sucked. Because i had to duplicate code for rotation to landscape. What do i have now? : CGSize titlesize = [title sizeWithFont:[UIFont systemFontOfSize:20] constrainedToSize:CGSizeMake(5, 90) lineBreakMode:UILineBreakModeWordWrap]; ttitleview = [[UITextView alloc] initWithFrame:CGRectMake(5, 5, 310,titlesize.height)]; ttitleview.text = title; ttitleview.font = [UIFont boldSystemFontOfSize:20]; ttitleview.backgroundColor = [UIColor clearColor]; ttitleview.editable = NO; [self.view addSubview:ttitleview]; CGSize textsize = [ttext sizeWithFont:[UIFont systemFontOfSize:20] constrainedToSize:CGSizeMake(5, 350) lineBreakMode:UILineBreakModeWordWrap]; tArea = [[UIScrollView alloc] initWithFrame:CGRectMake(5, titlesize.height, 310, 230)]; tArea.contentSize = CGSizeMake(310, textsize.height+20); tArea.pagingEnabled = FALSE; tArea.scrollEnabled = TRUE; tArea.backgroundColor = [UIColor clearColor]; [self.view addSubview:tArea]; ttextview = [[UITextView alloc] initWithFrame:CGRectMake(0, 0, 310, textsize.height + 20)]; ttextview.text = ttext; ttextview.font = [UIFont systemFontOfSize:20]; ttextview.backgroundColor = [UIColor clearColor]; ttextview.editable = NO; [tArea addSubview:ttextview]; But its no use. Looking for an elegant solution than this.

  • How can a program be detected as running?

    - by ryeguy
    I have written a program that is sort of an unofficial, standalone plugin for an application. It allows customers to get a service that is a lower priced alternative then the vendor-owned one. My program is not illegal, against any kind of TOS, and is certainly not a virus, adware, or anything like that. That being said, the vendor of course is not happy about me taking his competition, and is trying to block my application from running. He has already tried some tactics to stop people from running my app alongside his. He makes it so if it is detected, his app throws a fake error. First, he checked to see if my program was running by looking for an open window with the right title. I countered this by randomizing the program title at startup. Next, he looked for the running process name. I countered this by making the app copy itself when it is started as [random string].exe and then running that. Anyways, my question is this: what else can he do to detect if my program running? I know that you can read window text (ie status bar, labels). I'm prepared to counter this by replacing the labels with images (ugh, any other way?). But what else is there? Can you detect what .dlls a program has loaded? If so, could this be solved by randomizing the dll names before loading them? I know that it's possible to get a program's signature in memory and track it that way (like a virus scanner), but the chances of him doing that probably aren't good because that sounds pretty advanced. Even though this is kinda crappy of him to be doing, its kind of fun. It's like a nerdy fist fight. EDIT: When I said it's a plugin, that is just the (incorrect) term I used. It's a standalone EXE. The "API" between my program and the other is mine is simply entering data into the controls (like textboxes, etc).

  • Django apache-wsgi configuration problem

    - by omat
    Hi, I am trying to get my Django project running on the production server. I setup the environment using pip, so it is identical to the development environment where everything is running fine. The only difference is that I don't use virtualenv on production, because this project is the only one that is going to run on production. Also on production, there is an Nginx reverse proxy to serve static content, and passes dynamic requests to Apache2. The Apache wsgi file is as follows: import sys, os sys.path.append('/home/project/src') os.environ['DJANGO_SETTINGS_MODULE'] = 'settings' import django.core.handlers.wsgi application = django.core.handlers.wsgi.WSGIHandler() When I access the server, I get an import error: ImproperlyConfigured: Error importing middleware middleware: "cannot import name UserProfile" Which refers to the middleware.py under src/ folder which is referred by the settings. But I can import both the middleware and the UserProfile class from within ./manage.py shell prompt. It seems like a problem with paths in wsgi file but I cannot see what. The directory structure is: /home/project /home/project/src (which contains the settings.py, middleware.py and app folders) /home/apache/apache.wsgi Any help is greatly appreciated. Thanks, oMat

  • How do I use text in one cell to trigger row to be copied on another sheet in Excel?

    - by Brian Eby
    I provide all of the cut lists for our cabinet manufacturing in Excel. I tally all parts for the entire job on the first worksheet in an Excel file, and then filter the rows based on the "Material" column, and manually copy/paste each row in to its own material-specific worksheet (example: I filter "Materials" column for "Maple Ply", and then copy all "Maple Ply" rows to the "Maple Ply" worksheet). Then the material specific worksheets are sent to the shop floor for cutting. This is time consuming, and if I need to change any data in the first page, I have to go and manually update the copied row in its material-specific page. Is there any way to make each material page "look" for its material, and automatically populate itself with any row that has the appropriate material in the material column (example: any time I enter "Maple Ply" in the material column of sheet one, that row is automatically copied to the "Maple Ply" worksheet)? If so, could this link be dynamic, rather than just a copy, so that if I change a cell in a particular row on sheet one, that data is also updated on the material-specific worksheet copy? Thank you, Brian

  • Ajax Rich Internet Application framework for Linux + Firefox _AND_ iPhone consumption

    - by Maroloccio
    For a zero-budget (e.g. University) project we need to build a rich web UI for Firefox and iPhone clients. Firm requirement: all technologies to be free and open-source. Nice-to-have: all development to be done in Java/Eclipse. I generally like the Google's AppEngine + GWT combo but this project will require much more interactivity than what's in GWT 2.0. Something along the lines of: http://www.smartclient.com/smartgwt/showcase/. I know trusty plain ol' GWT won't cut it this time. Straight question: is there something that does the sort of thing that SmartGWT does and works really well on Safari/iPhone? I would say the mobile experience is even more important for this project than the desktop one. Optional question: perhaps this is not the best route to go at all? How could we otherwise render a rich UI with such capabilities and interactivity on both screen sizes? Windows, drag-and-drop, advanced tabs, dynamic grids... We don't need to support any other mobile devices. Yet. ;-)

  • Is there a PHP benchmark that meets these specific criteria? [closed]

    - by Alex R
    I'm working on a tool which converts PHP code to Scala. As one of the finishing touches, I'm in need of a really good (er, somewhat biased) benchmark. By dumb luck my first benchmark attempt was with some code which uses bcmath extensively, which unfortunately is 1000x slower in Java, making the Scala code 22x slower overall than the original PHP. So I'm looking for some meaningful PHP benchmark with the following characteristics: The PHP source needs to be in a single file. It should solve a real-world problem. No silly looping over empty methods etc. I need it to be simple to setup - no databases, hard-to-find input files, etc. Simple text input and output preferred. It should not use features that are slow in Java (BigInteger, trigonometric functions, etc). It should not use exoteric or dynamic PHP functions (e.g. no "eval" or "variable vars"). It should not over-rely on built-in libraries, e.g. MD5, crypt, etc. It should not be I/O bound. A CPU-bound memory-hungry algorithm is preferred. Basically, intensive OO operations, integer and string manipulation, recursion, etc would be great. Thanks

  • Bound checkbox does not update its datasource.

  • WPF validation red border doesn't show If UserControl collapsed first

    - by Creepy Gnome
    There seems to be a bug with WPF in 3.5, and I was hoping someone may have found a workaround. Basically if you have a custom UserControl that contains a TextBox and it is in a Window but initialized to be Collapsed by default in the xaml or code behind if it fails validation when you make the control visible it will not show the red border until it fails while visible. However, this works correctly when visibility is set to Hidden, just no when Collapsed. I am already overriding the ErrorTemplate with a style to workaround the Adornment issue with the red border staying visibile when you collapse the control. Below is my full style for the TextBox. If there is any additional changes or additions to make it work correctly with collapsed controls that would be great. <Style TargetType="TextBox"> <Setter Property="Margin" Value="3" /> <Setter Property="Validation.ErrorTemplate"> <Setter.Value> <ControlTemplate> <ControlTemplate.Resources> <BooleanToVisibilityConverter x:Key="converter" /> </ControlTemplate.Resources> <DockPanel LastChildFill="True"> <Border BorderThickness="2" BorderBrush="Red" Visibility="{ Binding ElementName=placeholder, Mode=OneWay, Path=AdornedElement.IsVisible, Converter={StaticResource converter}}" > <AdornedElementPlaceholder x:Name="placeholder" /> </Border> </DockPanel> </ControlTemplate> </Setter.Value> </Setter> <Style.Triggers> <Trigger Property="Validation.HasError" Value="true" > <Setter Property="ToolTip" Value="{Binding RelativeSource={RelativeSource Self}, Path=(Validation.Errors)[0].ErrorContent}" /> </Trigger> </Style.Triggers> </Style>

  • Need a code snippet for backward paging...

    - by Ali
    Hi guys I'm in a bit on a fix here. I know how easy it is to build simple pagination links for dynamic pages whereby you can navigate between partial sets of records from sql queries. However the situation I have is as below: COnsider that I wish to paginate between records listed in a flat file - I have no problem with the retrieval and even the pagination assuming that the flat file is a csv file with the first field as an id and new reocrds on new lines. However I need to make a pagination system which paginates backwards i.e I want the LAST entry in the file to appear as the first as so forth. Since I don't have the power of sql to help me here I'm kinda stuck - all I have is a fixed sequence which needs to be paginated, also note that the id mentioned as first field is not necessarily numeric so forget about sorting by numerics here. I basically need a way to loop through the file but backwards and paginate it as such. How can I do that - I'm working in php - I just need the code to loop through and paginate i.e how to tell which is the offset and which is the current page etc.
