• JSF Render response programatically

  - by Shamik

  I have one parent page with a parentManagedBean (attached to Session Scope). On click of a button on this parent page, one popup comes which has a childManagedBean (attached to Request scope). Now ChildManagedBedan holds a reference to parentManaged bean thru JSFs managed Property feature. On this popup window, user selects some option which populates a large value object class. I use the managed property of childMnaagedBean to set the values from this large object to that of parentmanagedbean. Problem is - The parent page shows a link, on click of which a popup comes, on selection of the popup, the popup disappears and set the values to the parentManaged bean.So far so good, but the newly set values need to appear on the parent page. This is where I am stuck. How to programatically render the master page/render page when I am at the child managed bean... is there a way I can get handle of the parent page and refresh it ?

• Retweet button in asp.net site

  - by Zerotoinfinite

  Hi All, I am using asp.net 3.5 and C# for my personal blog site. I want to include retweet\tweet button on every post I have made, for this I have some query. I have made the account on twitter with my website name. As I want to check the individual tweets for each of my post, do I have to create new account for each post or do I have to include new list for each post. As my post has the url something like this www.mywebsite.net/myblog.aspx?id=9 , with this id I am recognising the post. Then how would I write the reference URL to the retweet button for each & every post. Thanks in advance. Please let me know if the information provided by me requires more details.

• dynamically created datagridview columns not accessible unless added to a form...why?

  - by deostroll

  We simply created a DataGridView control dynamically and bound it to a DataTable. We were tying to style certain columns. But, when we tried to access the columns we got a null reference. On further investigation we found that if we add the DataGridView control to the main form, and then try to access its columns, it works fine!!! Code which throws error: DataGridView gv = new DataGridView(); gv.DataSource = GetDataTable(); //binding it to datatable Debug.Assert(gv.Columns == null); Code which works fine: DataGridView gv = new DataGridView(); gv.DataSource = GetDataTable(); //binding it to datatable this.Controls.Add(gv); //adding to form Debug.Assert(gv.Columns == null); //the assertion fails! Why is this behaviour so? Is there a workaround for this?

• UITableViewCell repeating problem

  - by cannyboy

  I have a UItableview with cells. Some cells have uilabels and some have uibuttons. The UIbuttons are created whenever the first character in an array is "^". However, the uibuttons repeat when i scroll down (appearing over the uilabel).. and then multiply over the uilabels when I scroll up. Any clues why? My voluminous code is below: - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { const NSInteger LABEL_TAG = 1001; UILabel *label; UIButton *linkButton;

• Caching linked pages in ASP.NET

  - by n0e

  I'm thinking of a way of creating a local backup for the pages I will be linking to from my site. This would be text-only, similar to Google's 'Copy' feature on the search pages. The idea is to be sure that the pages I would reference to, or cite from, do not dissapear from the Web in the near future. I know I could just keep local copies, but I will have A LOT of citations. What would be the best way of achieving this in ASP.NET? Some custom caching in database?

• UILabel reset after Autorotate

  - by MB

  Hi, I have a UILabel in a view that is set by calling a method against my view controller. The app is a TABBar app and the VC is in the MORE section. When I rotate the phone the label disappears (don't mind that) when I rotate back the label is showing all .......... (the value it is set to in the XIB) I added a line to set the label in the shouldAutoRotateToOrientation method lblProductTxt.titleLabel.text = self.productText; when autorotating what viewcontroller methods are being called. ?? the shouldAutoRotateToOrientation method doesn't get called when the VC is in the More section but when I move it it does get called but has no affect on the labeltext

• What is the proper way to create a recursive entity in the Entity Framework?

  - by Orion Adrian

  I'm currently using VS 2010 RC, and I'm trying to create a model that contains a recursive self-referencing entity. Currently when I import the entity from the model I get an error indicating that the parent property cannot be part of the association because it's set to 'Computed' or 'Identity', though I'm not sure why it does it that way. I've been hand-editing the file to get around that error, but then the model simply doesn't work. What is the proper way to get recursive entities to work in the Entity Framework. CREATE TABLE [dbo].[Appointments]( [AppointmentId] [int] IDENTITY(1,1) NOT NULL, [Description] [nvarchar](1024) NULL, [Start] [datetime] NOT NULL, [End] [datetime] NOT NULL, [Username] [varchar](50) NOT NULL, [RecurrenceRule] [nvarchar](1024) NULL, [RecurrenceState] [varchar](20) NULL, [RecurrenceParentId] [int] NULL, [Annotations] [nvarchar](50) NULL, [Application] [nvarchar](100) NOT NULL, CONSTRAINT [PK_Appointments] PRIMARY KEY CLUSTERED ( [AppointmentId] ASC ) ) GO ALTER TABLE [dbo].[Appointments] WITH CHECK ADD CONSTRAINT [FK_Appointments_ParentAppointments] FOREIGN KEY([RecurrenceParentId]) REFERENCES [dbo].[Appointments] ([AppointmentId]) GO ALTER TABLE [dbo].[Appointments] CHECK CONSTRAINT [FK_Appointments_ParentAppointments] GO

• How beneficial is this subject combination for an undergrad CS student?

  - by Maxood

  I'm an undergrad Computer Science student and studying online. There is a lot of self study, independent research and practice i have to do myself. I wonder how beneficial would it be to choose this subject combination in programming: Data Structures OOP Assembly Language & Computer Architecture Although i also have the option to take DLD (Digital Logic Design) or Data communication courses instead of Assembly Language. My interest lies in programming and i'm also working as a programmer at local software house. Can anyone give me some good advice and suggestions.

• Strange behaviour with Microsoft.WindowsCE.Forms

  - by Mohammadreza

  I have a Windows Mobile application in which I want to check the device orientation. Therefore I wrote the following property in one of my forms: internal static Microsoft.WindowsCE.Forms.ScreenOrientation DeviceOriginalOrientation { get; private set; } The strange thing is that after that whenever I open a UserControl, the designer shows this warning even if that UserControl doesn't use the property: Could not load file or assembly 'Microsoft.WindowsCE.Forms, Version=3.5.0.0, Culture=neutral, PublicKeyToken=969db8053d3322ac' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040) Commenting the above property will dismiss the warning and shows the user control again. The application is built successfully and runs without any problems in both cases. Does anybody know why this happens and how can I fix it?

• Java: confirm method Binary division and find remainder is correct?

  - by cadwag

  I am parsing binary files and have to implement a CRC algorithm to ensure the file is not corrupted. Problem is that I can't seem to get the binary math working when using larger numbers. The example I'm trying to get working: BigInteger G = new BigInteger("11001", 2); BigInteger M = new BigInteger("1110010000", 2); BigInteger R = M.remainder(G); I am expecting: R = "0101" But I am getting: R = "1100" I am assuming the remainder of 0101 is correct since it is given to me in this book I am using as a reference for the CRC algorithm (it's not based in Java), but I can't seem to get it working. I can get small binary calculations to work that I have solved by hand, but not the larger ones. I'll admit that I haven't worked the larger ones by hand yet, that is my next step, but I wanted to see if someone could point out a glaring flaw I have in my code. Can anyone confirm or deny that my methodology is correct? Thanks

• Can I make controls defined in my markup public instead of protected

  - by RoboShop

  Say I have a web site with a master page and an aspx page. In my ASPX page, I am pointing to my masterpage with the MasterType tag. <%@ MasterType VirtualPath="~/mymasterpage.master" % Say, I've defined a label in the markup of my master page. If you look at the designer code, this label should be something like this. protected global::System.Web.UI.WebControls.Label label1; Now in my content page, I would like to reference this label. If I type in this "Master.label1", the complier will complain that the control is inaccessible due to the protection level" and rightly so, as label1 is automatically defined as "protected". My question is, if I define controls in my markup page, is it possible to set these controls as public instead of protected? I do not see an attribute for it. thanks in advance.

• Error loading Variables stage.loaderInfo - AS3

  - by Dimitree

  I have a Document class that loads variables from Facebook with the use of stage.loaderInfo var connect:FacebookConnectObject = new FacebookConnectObject( facebook, API_KEY, this.stage.loaderInfo ); But when I change the Document class (with another one responsible for the layout of my app), and try call the above from a movieclip that exists in my application with the use: var facebook_class:FacebookAp = new FaceBppkApp addChild(facebook_class) I get error TypeError: Error #1009: Cannot access a property or method of a null object reference. I believe the error comes fro this line this.stage.loaderInfo since I changed the scope... How I am supposed to fix that?

• Spring - MVC - Sanitize URL before redisplaying to the user

  - by Raghav

  In my application , a HTTP GET request URL to the application with script tag is getting redisplayed as it is although it fails the authorization. Example: http://www.example.com/welcome<script>alert("hi")</script> The issue is sanitizing external input entered directly into address bar by modifying existing GET URL. Spring redisplays the submitted URL as it is. Though the script does not get executed in the browser(FF), is there anyway to strip the URL of these values before displaying it back to the user Reference: Spring MVC application filtering HTML in URL - Is this a security issue?

• Looking for some thoughts on an image printing app

  - by Alex

  Hey All, Im looking for thoughts/advice. I have an upcoming project (all .net) that will require the following: pulls data once a day from an online service provider based on certain criteria. saves data locally for reference and reporting the data thats pulled will be used to create gift cards. So after the data is loaded, a process will run to generate "virtual cards" and send them to a network printer. Once printed, the system will updated the local data recording a successful or failed print. My initial thought was to create a windows service to pull the data...but then I couldnt decide how I was going to put a "virtual card" together and get it to print. Then I considered doing it as a WPF app. I figure that will give me access to the graphics and printing ability. Maybe neither of these are the right direction....Any ideas or thoughts would be greatly appreciated. Alex

• Use of Java constructors in persistent entities

  - by Mr Morgan

  Hello I'm new to JPA and using persistence in Java anyway and I have two questions I can't quite work out: I have generated tags as: @JoinColumn(name = "UserName", referencedColumnName = "UserName") @ManyToOne(optional = false) private User userName; @JoinColumn(name = "DatasetNo", referencedColumnName = "DatasetNo") @ManyToOne(optional = false) private Dataset datasetNo; But in one of the constructors for the class, no reference is made to columns UserName or DatasetNo whereas all other columns in the class are referenced in the constructor. Can anyone tell me why this is? Both columns UserName and DatasetNo are 'foreign keys' on the entity Visualisation which corresponds to a database table of the same name. I can't quite work out the ORM. And when using entity classes, or POJO, is it better to have class variables like: private User userName; Where an instance of a class is specified or simply the key of that class instance like: private String userName; Thanks Mr Morgan.

• Update webreference gives troubles with different versions of dll

  - by Natrium

  In my application, I use some dll, let's say library.dll, version 1.0 In my webservice, I also use library.dll, but version 2.0 When I do an update of the webreference, the classes inside of the dll are also generated in the webreference. And this gives troubles because in my application, the classes that are defined in the dll now are also available in the reference and there is a mismatch. How can I solve this? I need to be able to tell the webservice to ignore the dll-code when updating the webreference in the one or the other way. I use Visual Studio 2008.

• Help with complex sql query

  - by eugeneK

  To make story short, i'm building self-learning banner management system. Users will be able to insert these banners to their site when banners will be shown based on sales/impressions ratio. I have 4 tables Banners bannerID int bannerImage varchar.... SmartBanners smartBannerID int smartBannerArrayID int bannerID int impressionsCount int visibility tinyint (percents) SmartBannerArrays smartBannerArrayID int userID int Statistics bannerID int saleAmountPerDay decimal... Each night i need to generate new "visibility" for each SmartBanner based on whole SmartBannerArray that same user has. So i need to get sum of impressions and sales for each bannerID in SmartBannerArray. All comes to my mind is to use double cursor, one will loop thought SmartBannerArrays get needed values for sum of impressions and sales and then inner loop which will access each SmartBanner and change it's "visibility" percentage based on (sales/impressions)/(sumOfSales/sumOfImpressions)*100 Hope you get the picture... Is there any other way to design better tables or not to use double cursor to avoid server overload ?

• Bitbanging a PIO on Coldfire/ucLinux

  - by G Forty

  Here's the problem: I need to program some hardware via 2 pins of the PIO (1 clock, 1 data). Timing constraints are tight - 10ms clock cycle time. All this, of course, whilst I maintain very high level services (CAN bus, TCP/IP). The downstream unit also ACKS by asserting a PIO pin, configured as an input, high. So this loop has to both read and write. I need to send 16 bits in the serial stream. Is there an established way to do this sort of thing or should I simply get the hardware guys to add a PIC or somesuch. I'd much prefer to avoid exotics like RTAI extensions at this stage. I did once see a reference to user-mode IO which implied a possible interrupt driven driver but lost track of it. Any pointers welcomed.
