• Using a UIPickerView to make a CoreData Relationship

  - by DVG

  Okay, so I have a fairly simple application set up. I have two different CoreData Entities, Games and Platforms, each have one attribute: name, and they have a one-to-many relationship between them. Platforms are populated on the first launch of the application, and will never change as a result of user input. I'm working on my Add view to let the user add new games to their personal database, and each game should select from a platform. The add view itself is a grouped table view with static custom cells. Tapping the platform cell should advance the user to another view to select the platform. My thought is that UIPickerView seems like a logical choice for the control, since the Platform list is static, but I'm not sure how to use it with CoreData. Even if I construct a fetch request to get the Platform objects and extract the strings out, how do I go about linking the new Game object to the original Platform object?

• ASP Calendar control returns Date type but I need Datetime to insert into SQL Server 2005

  - by rafael

  Hello, I am using a ASP Calendar control to insert a datetime value into a field to be part of an insert to a SQL Server 2005 db table. I get the following error when i submit the form to server and try to insert into table: [ArgumentException: The version of SQL Server in use does not support datatype 'date'.] Seems like Calendar control returns a Date type value. How could i make the Calendar control return a Datetime value instead? I know now that SQL Server 2005 does not support Date type fields.

• How to add request validation errors to ModelStateDictionary in ASP.NET MVC?

  - by Morten Christiansen

  Investigating the security of a system I'm building with ASP.NET MVC 2 led me to discover the request validation feature of ASP.NET - a very neat feature, indeed. But obviously I don't just want to present the users with the Yellow Screen of Death when they enter data with HTML in, so I'm out to find a better solution. My idea is to find all the fields that have invalid data and add them to the ModelStateDictionary before invoking the action such that they automatically appear in the UI as error messages. After googling this a bit it appears that no one have implemented this before which I find puzzling since it seems so obvious. Does anyone here have a suggestion on how to do this? My own idea is to supply a custom ControllerActionInvoker to the controller, as described here, that somehow checks for this and modifies the ModelStateDictionary but I'm stuck on how to do this last bit. Just catching HttpRequestValidationException exceptions does not seem a useful approach since it does not actually contain all the information I need.

• Specify Windows Service Name on install with Setup Project

  - by sympatric greg

  Objective: In support of a Windows Service that may have multiple instances on a single machine, use a Setup Project to create an MSI capable of: Receiving user input for Service Name Installing service Serializing Service Name from 1 (so that the proper name can be used in logging and uninstall) My initial hope was to set Service Name in App.config (and then retrieve it during uninstall upon instantiation of the ServiceInstaller. This seems to have been naive, because it is not accessible during the install. If MyInstaller extends Installer, it can call base.Install(); however, my attempts to write to app.config (within MyInstaller.Install() and after base.Install()) are inneffective. So while the service can be installed with a custom Service Name, that name is not serialized and the installer is most displeased upon uninstall. How should this be done?

• Why does Chrome incorrectly determine page is in a different language and offer to translate?

  - by Sam

  The new Google Chrome auto-translation feature is tripping up on one page within one of our applications. Whenever we navigate to this particular page, Chrome tells us the page is in Danish and offers to translate. The page is in English, just like every other page in our app. This particular page is an internal testing page that has a few dozen form fields with English labels. I have no idea why Chrome thinks this page is Danish. Does anyone have insights into how this language detection feature works and how I can determine what is causing Chrome to think the page is in Danish?

• Outlook 2003 Add-In Setup Project with COM DLL Deployment Problem

  - by Malkier

  Hi, I developed an Outlook 2003 add-in which uses the com dll redemption. I created a visual studio 2008 setup project, added a custom action to run "caspol.exe -machine -addgroup 1 -strong -hex [key] -noname -noversion FullTrust -n \"Name\" -description \"desc\" and moved the registry keys under software to HKLM as described in http://msdn.microsoft.com/en-us/library/cc136646.aspx#AutoDeployVSTOse_InstallingtheAddinforAllUsers to ensure all-users compatibility. I included the redemption.dll in the setup with vsdrfCOMSelfReg (vsdrfCOM throwed an error). My problem is: When installing the setup on a test machine under an admin account, it runs fine under all users, however when we use the company wide software deployment which runs under a system account the setup executes but the add-in wont load. If I repair the installation with an admin account again it loads just fine. Shouldn't a system account have the required permissions to install all of the components? What options do I have? Thanks for any suggestions.

• How do I get a TextBox to only accept numeric input in WPF?

  - by Giffyguy

  I'm looking to accept digits and the decimal point, but no sign. I've looked at samples using the NumericUpDown control for WinForms, and this sample of a NumericUpDown custom control from Microsoft. But so far it seems like NumericUpDown (supported by WPF or not) is not going to provide the functionality that I want. The way my app is designed, nobody in their right mind is going to want to mess with the arrows. They don't make any practical sense, in the context of my app. So I'm looking for a simple way to make a standard WPF TextBox accept only the characters that I want. Is this possible? Is it practical? Thanks, SO!

• ExpressionEngine: Why is this {exp:query} tag producing an error?

  - by Josh Brown

  Hi. I have this code in place to pull some relation data from the database based on a ID of another weblog entry. The relationship custom field would not work for my situation. I have tested the SQL with MySQL and get no errors. But I get an error when I pull up the page. {exp:query sql="SELECT entry_id,field_id_16,field_id_19 FROM exp_weblog_data WHERE field_id_15='2' AND weblog_id='6'"} Also, I want to populate the “field_id_15” from the url. I have tried using the “segment_*” tag, but nothing. Maybe it is something else. Any help is greatly appreciated. Thanks, Josh

• Imports and Depends

  - by David Diez

  I have read two recent posts that discuss Depends and Imports but I have four lingering, related questions: Suppose I want two packages to also be available to the end-user when they load in my package. Is there a good reason not to use Depends in this context? (The point here is to load all three packages via a command that loads just the one package.) Is it okay to specify a package in both the Depends and Imports fields? If a package is listed in Depends, is there a point to also listing it in Imports? Or are the benefits of Imports already negated by using Depends? [Added Question] Is the following correct? A package should be listed in the Imports field of the DESCRIPTION file if and only if the package is imported (in whole or in part) in the NAMESPACE file. Thanks much! David

• NetBeans not finding JasperReports scriptlet

  - by Sean

  I'm using JasperReports 3.7.6 with NetBeans 6.9.1 and iReport 3.7.6. I have a report that uses scriptlets. When I run it from iReport everything is fine because I can tell iReport where to find the .jar file with the scriptlets. When I run that same report from a JSF-2.0 application the fields that rely on the scriptlet are not being populated correctly - i.e. the scriptlet isn't being called. I've tried putting the scriptlet in the project's library folder and I've tried copying the package containing the scriptlet into the project. Neither has worked. I'm not sure how I can get the report to call the scriptlets when it is run from my JSF project. Can anyone shed some light on this for me?

• SqlCommand() ExecuteNonQuery() truncates command text.

  - by H. Abraham Chavez

  I'm building a custom db deployment utility, I need to read text files containing sql scripts and execute them against the database. Pretty easy stuff, so far so good. However I've encountered a snag, the contents of the file are read successfully and entirely, but once passed into the SqlCommand and then executed with SqlCommand.ExecuteNonQuery only part of the script is executed. I fired up Profiler and confirmed that my code is not passing all of the script. private void ExecuteScript(string cmd, SqlConnection sqlConn, SqlTransaction trans) { SqlCommand sqlCmd = new SqlCommand(cmd, sqlConn, trans); sqlCmd.CommandType = CommandType.Text; sqlCmd.CommandTimeout = 9000000; // for testing sqlCmd.ExecuteNonQuery(); } // I call it like this, readDMLScript contains 543 lines of T-SQL string readDMLScript = ReadFile(dmlFile); ExecuteScript(readDMLScript, sqlConn, trans);

• C# Lambda Expression Speed

  - by Nathan

  I have not used many lambda expressions before and I ran into a case where I thought I could make slick use of one. I have a custom list of ~19,000 records and I need to find out if a record exists or not in the list so instead of writing a bunch of loops or using linq to go through the list I decided to try this: for (int i = MinX; i <= MaxX; ++i) { tempY = MinY; while (tempY <= MaxY) { bool exists = myList.Exists(item => item.XCoord == i && item.YCoord == tempY); ++tempY; } } Only problem is it take ~9 - 11 seconds to execute. Am I doing something wrong is this just a case of where I shouldn't be using an expression like this? Thanks.

• Dashcode and firefox compatibility

  - by nacho4d

  Hi all, I started to use Dashcode with a Safari Custom Project, my apps work fine, but StackLayout Object does not work in Firefox. I know Dashcode use many wekbit-specific things but is there any way I can get StackLayout object o work in Firefox? I would not mind losing some fancy stuff like transition-animations as long as my Views change. StackLayout also does not work in IE, but I think that is too much to expect from IE. lol. Any suggestions, ideas? Maybe jQuery or Dojo libraries can be used with DashCode in case webkit is not available?. in this case how can I do this? Thanks.

• Best way to handle multiple getView calls from inside an Adapter

  - by Samuh

  I have a ListView with custom ArrayAdapter. Each of the row in this ListView has an icon and some text. These icons are downloaded in background,cached and then using a callback, substituted in their respective ImageViews. The logic to get a thumbnail from cache or download is triggered every time getView() runs. Now, according to Romain Guy: "there is absolutely no guarantee on the order in which getView() will be called nor how many times." I have seen this happen, for a row of size two getView() was being called six times! How do I change my code to avoid duplicate thumbnail-fetch-requests and also handle view recycling? Thanks.

• Is there any project estimation tool to give estimate for web design/ development work?

  - by jitendra

  Is there any project estimation tool which gives estimates for web design/ development work? I don't have to calculate Price just want to calculate estimated time. Just for example, for things like: Page creation (layout in XHTML) CSS creation Content creation (Word to HTML, including images in some pages) Bulk PDF upload PHP Script for Form Testing all pages I need like Items Quantity Time for each task(min) Estimated total (in hour) PDF upload x 30 = 2 min = 60 Min pages with images x 30 = 15 min for each = 60 Min Is there any simple JQuery calculator power with JQuery? Where we can add add/remove custom thing to calculate time? Or any other free online/offline tool ?

• How can I set a highlighted image on a table view cell?

  - by nevan

  I've followed the code in Apple's AdvancedTableViewCells and built a table view with a background image for cells. Now I want to change it so that instead of the blue highlight colour, it shows a darker version of my image. What are the steps I need to follow to do this? I'm using a UITableViewCell subclass with a custom NIB. My background image is implemented as the cell.backgroundView. The steps I've take so far are: Change the selectionStyle of the cell to "None" Set the Highlight colour on my UILabel subviews to a light colour Create a darker version of my background as a separate image Override setSelected: animated: I'm wondering about the next steps.

• ASP.NET MVC 2.0 Client-Side Validation HOWTO

  - by AlexWalker

  Where can I find some good information on the new client-side validation functionality included in ASP.NET MVC v2? I'd like to find information about using the client-side validation JavaScript without using DataAnnotations, and I'd like to find out how custom validations are handled. For example, if I want to validate two fields together, how would I utilize the provided JavaScript? Or if I wanted to write validation code on the server-side that queried a database, how could I use the provided JavaScript to implement a similar validation? I don't see any books on MVC2 yet, and the blog entries I've found are not detailed enough.

• iTunes Music Store Link Maker — how to search from within my app?

  - by prendio2

  I'm writing a music reference app and for each album (pulled from last.fm) would like to link to the ITMS (if the album is in the store). iTunes link maker web tool http://apple.com/itunes/linkmaker/ is great for getting links for a known album but I need to access it programatically from within my app. This NSLog blogpost which is from 2003 but was referenced more recently in another question here seems to offer the only solution I've come across so far, suggesting to submit a query to: phobos.apple.com/WebObjects/MZSearch.woa/wa/advancedSearchResults? Put "itms://" before it and the link will work in iTunes, put "http://" before it and the link will work in Camino (Safari sometimes spits back a malformed XML error). The tags that are of importance are as follows: songTerm - song title artistTerm - artist name albumTerm - album name composerTerm - composer name term - all fields The suggestion is that would using http:// rather than itms:// the server will return an XML document of results instead of opening iTunes but either way I am sent directly to iTunes. Is it possible to get back a list of results?

• TinyMCE or HTML5's contentEditable attribute?

  - by Mike

  I have always hated wysiwyg editors but most of the applications I develop they are necessary for our clients to edit their content. After trying out a few different ones I seemed to like tinyMCE the best. Although powerful and seems to generate fairly good HTML it is not without its issues. Recently I have been thinking about creating a custom wysiwyg that suits my needs perfectly taking advantage of the contentEditable attribute. Is this HTML5 feature ready? Will I have many cross browser issues? What are its limitations? I guess my question finally boils down to; Will it be worth throwing in the towel on 3rd party wysiwygs and moving to contentEditable regions?

• Data sync solution?

  - by user321088

  For some security issues I'm in an envorinment where third party apps can't access my DB. For this reason I should have some service/tool/script (dunno what yet... i'm open to the best option, still reading to see what I'm gonna do...) which enables me to generate on a regular basis(daily, weekly, monthly) some csv file with all new/modified records for a certain application. I should be able to automate this process and also export at any time a new file. So it should keep track for each application which records he still needs. Each application will need some data in some other format (csv/xls/sql), also some fields will be needed for some application and some aren't... It should be fairly flexible... What is the best option for me? Creating some custom tables for each application? Based on that extracting modified data?

• Nonstandard SSIS lookup

  - by Stefan

  I have a situation where I am trying to lookup a value in one table based on values in another table, using a BETWEEN operator and not an = operator. In one table, I have a value "EffectiveDate". I want to get a Weight number from another table, but the other table has two fields: "Inception" and "Termination". What I want to do is extract the Weight from that table for use where the EffectiveDate is between Inception and Termination. SSIS doesn't seem to provide a way to do this. It's good at matching one column to another column, but doesn't seem to allow one to many-column comparison/operations. Am I missing anything? Is this possible to do somehow?

• Clearing "may not respond" warnings for UIView and UIViewController

  - by user284681

  In an iPad app, I'm using a custom subclass of UIView with UIViewController. Here's the view header: @interface pdfView : UIView { CGPDFDocumentRef doc; } -(void)setDoc:(CGPDFDocumentRef)newDoc; @end And here's the controller header: @interface iPadPDFTestViewController : UIViewController { CGPDFDocumentRef doc; } - (void)loadPDF; @end Part of the controller implementation: - (void)viewDidLoad { [super viewDidLoad]; [self loadPDF]; [self.view setDoc:doc]; } In Interface Builder, I've set the view object to use the class pdfView. At compilation, [self.view setDoc:doc]; gives the warning "'UIView' may not respond to '--setDoc'." I'm guessing that this warning appears because the compiler thinks it's looking at UIView (which does not implement the setDoc method) instead of pdfView. But why does it think that? And how can I tell it what class it's really looking at, so as to clear the warning?
