• Porting a PowerBuilder Application to .NET

  - by Justin Ethier

  Does anyone have any advice for migrating a PowerBuilder 10 business application to .NET? My company is considering migrating a legacy PB application to .NET (C#) and I am just wondering if anyone has any experience - good or bad - that you would like to share. The application is rather large with 10 PBL libraries, some PFC as well as custom frameworks. There are a large number of DLL calls being made as well. Finally, it uses a Microsoft SQL Server database. We have discussed porting the "core" application code to .NET and then porting more advanced functionality across as-needed.

• XMLEncoder and PersistenceDelegate

  - by Johannes Rössel

  I'm trying to use XMLEncoder to write an object graph (tree in my case) to a file. However, one class contained in it is not actually a Java bean and I don't particularly like making its guts publicly accessible. It's accessed more like a list and has appropriate add methods. I've already written a custom PersistenceDelegate to deal with that. However, is there any way for XMLEncoder to pick it up on its own or do I really need to add it whenever I use an encoder to write a graph that may contain said class?

• execute javascript before return in php

  - by user354051

  I do have a custom php script that validates captcha code and sends an email. If php script is sending a mail successfully then it returns "true". This is done by: if(!$Error){ echo "true"; exit; } Before returning true, I would like to execute a jQuery command that should refresh the captcha image. I shouldn't be doing this is client side as it might be risky from spammers point of view. To refresh the captcha image, The command is: jQuery('#captcha').attr('src', ('php/captcha/captchaimage_show.php?' + Math.random())); I need to call this command from within php scripts before return any results by "echo" Prashant

• Clickable links in UILabel?

  - by lope

  Hi there, I have been searching for this for hours but I failed. I probably don't even know what should I be looking for. Many applications have text and in this text are web hyperlinks in rounded rect, when I click them UIWebView opens. What puzzles me is that they often have custom links, for example if words starts with # it is also clickable and aplication responds by opening another view. How can I do that? Is it possible with UILabel or do I need UITextView or something else? I really hope it is standard functionality and i don't need to subclass anything :/

• How can should I set up Flex 3 projects that reference common controls?

  - by Amy

  I'm not a flash developer, I'm having issues figuring out how I should set up these two projects that I have in Flex Builder. I've already created projA which has a .mxml that references several custom controls & skins from com.xxx.controls within projA I now have to build projB which also has a .mxml that will create a different .swf. I want to use some of the same controls from projA I currently build projA through the command line and nant and will need to do the same for projB. Should I create a new project to move all of the common controls into? How do I then use this library project in both the projects & compile via command? Thanks!

• Android Jar libraries

  - by Jeremy Edwards

  How do you setup a project that can result in a jar library file that can be used for android? I want to create a custom library across all projects. Few other questions: Does it need to be compiled against a specific version of android sdk? When an android package is compiled against a jar library does the classes necessary to work with the code get compiled with main code into the apk or does the entire jar get included? Any notable optimizations or pitfalls I need to know about with using a jar instead of integrating the code directly? Does the jar have to be signed like the apk needs to?

• How can I detect 'any' ajax request being completed using jQuery?

  - by Brian Scott

  I have a page where I can insert some javascript / jquery to manipulate the output. I don't have any other control over the page markup etc. I need to add an extra element via jquery after each present on the page. The issue is that the elements are generated via an asynchronous call on the existing page which occurs after $(document).ready is complete. Essentially, I need a way of calling my jquery after the page has loaded and the subsequent ajax calls have completed. Is there a way to detect the completion of any ajax call on the page and then call my own custom function to insert the additional elements after the newly created s ?

• How to send all previously generated data to new Flex client when using BlazeDS streaming?

  - by Sergey

  Hello. I have a Flex client and Java back-end connected with each other via BlazeDS. I use streaming for real-time data push from server to client. Everything works fine, but I want to add the following functionality: when the new client opens Flex application, he must receive all previously generated data instead of just subscribing to data updates. It seems like I have to save this data at the web server - that's pretty straightforward, but how can I push this data to new client when he connects? Should I use custom ServiceAdapter or there is a better way to achieve this purpose?

• Sharepoint navigation customization

  - by ifunky

  Hi, I've just started to use Sharepoint 2007, MOSS is installed but for the extranet I'm working on the publishing isn't switched on. What I need to do is customise the global navigation so that it displays all top level & subsite links, custom links and format it nicely with css for the brand. Sounds easy but it isn't for some reason! I've been reading numerous blogs and things about it but can't seem to find anything other than writing lots of code (which I don't mind) to hook into the API or use a customer provider which sounds extreme for something so simple. I was wondering what are the options for this and any good links to articles appreciated so I can finally get this simeple task done. I see the MOSS navigation has extra options for global navigation but I presume as this isn't enabled I couldn't use the same code/control in the master page? Thanks Dan

• best approach to do jsf form validation

  - by gurupriyan.e

  If I have many input controls in a form (There are separate validators for each of these input controls - like required,length and so on ) , there is a command button which submits the form and calls an action method. The requirement is - though the input control values are , say , individually okay - the combination of these values should be okay to process them together after the form submission - Where do i place the code to validate them together? 1) Can i add a custom validator for the command button and validate the combination together? like validate(FacesContext arg0, UIComponent arg1, Object value) but even then I will not have values of the other input controls except for the command button's/component's value right ? 2) can i do the validation of the combination in the action method and add validation messages using FacesMessage ? or do you suggest any other approach? Thanks for your time.

• Flagging complex properties as Browsable in the compact framework

  - by Rowland Shaw

  I'm working on a compact framework project and whilst most of the properties are fairly straight forward (I.e. mark them as browsable in the xmta file), I'm struggling to get this to work for more complex types - on the full framework, I'd just implement a custom TypeConverter and go from there, but it seems the CF TypeConverter doesn't have any of the type converting methods to override, which has left me a little stuck? It probably should be blindingly obvious but how would I go about supporting design time property support for more complex types (for the sake of argument, assume I can already convert to and from a string, but I'd prefer to keep this strongly typed, rather than just pretend it was a string and parse it both ways. Where should I be looking to achieve this?

• C# How to create objects without class definitions?

  - by JL

  Is it possible to create objects at designtime without having to have hard coded class definitions, then populate properties with primitives or even strongly typed data types? This might sound confusing, so I will attempt to give you a use case scenario. Use case: You have an XML config file that could hold configuration values for connecting to various systems in an SOA application. In C# the XML file is read, but for each system the configuration properties are different (e.g: SQL might have a connection string, while SharePoint might need a username + password + domain + url, while yet an smtp server would need username + password + port + url) So instead of creating static classes as follows public class SharePointConfiguration or public class SQLConfiguration, then have each class with custom properties (this is cumbersome) or using a 1990's method, an arrayList or some named collection Is there not a more preferred way to achieve this? Taking advantage of new language features, that can still offer design time intellisense, which would make the code easier to maintain and less prone to error. Thanks

• Need help with Drupal bulk mail low open rate for legitimate mailing list

  - by Ron Williams

  I've moved from constant contact to Drupal Simplenews/Mimemail/SMTP. Previously the open rate was around 50% for constant contact, but now it's 4-5% for the same list via the mentioned setup. Mail is getting out from the server, but it's having an issue anyway. Here's the setup: -The e-mail list consists of approximately 80,000 addresses which is queued at 10,000 e-mails per cron run (which runs hourly). -The server is a Dual Core2Quad machine with 2GB of RAM. -When mail is being sent, the mail queue will usually go up to ~1000 at the beginning of the hour before reducing to ~250 by the time the next cron occurs. -Newsletter is themed to display custom style for newsletter on send -Newsletter is received by some, but appears to be bounced by many (based on low open rate_ -I've added SPF, domain keys, and a PTR record to the DNS -Server hostname (listed in ptr) is different from hosted domain -Very low spam number via Spamassassin -IP and domain are not blacklisted -Mail goes out via SMTP module on delivery. Any ideas?

• Convert long number as string in the serialization

  - by Bruno

  I have a custom made class that use a long as ID. However, when I call my action using ajax, my ID is truncated and it loses the last 2 numbers because javascript loses precision when dealing with large numbers. My solution would be to give a string to my javascript, but the ID have to stay as a long on the server side. Is there a way to serialize the property as a string? I'm looking for some kind of attribute. Controller public class CustomersController : ApiController { public IEnumerable<CustomerEntity> Get() { yield return new CustomerEntity() { ID = 1306270928525862486, Name = "Test" }; } } Model public class CustomerEntity { public long ID { get; set; } public string Name { get; set; } } JSON Result [{"Name":"Test","ID":1306270928525862400}]

• How do I make the Drupal-Core Forum display only to members, and ask for login details otherwise

  - by Busk

  I'm trying to create a website, that has a menu based on Primary Links on the top of the site. The one menu item is for a 'Members Forum'. I want this menu item visible to all users (Anonymous/Authorized), but if an Anonymous user clicks on the item, instead of displaying "Access Denied", I'd prefer to show a custom message "such as please login to access the forum". If an Authorized user clicks it, obviously I want them to go straight to the page. In the Forum module, I've set up a container for the forum that is only viewable for Authorized users, so that when an Anonymous user clicks the menu item, they get the Access Denied error. Thank you

• Why isn't my log4net appender buffering?

  - by Eric

  I've created a custom log4net appender. It descends from log4net.Appender.SmtpAppender which descends from log4net.Appender.BufferingAppenderSkeleton. I programatically setup the following parameters in its constructor: this.Lossy = false; //don't drop any messages this.BufferSize = 3; //buffer up to 3 messages this.Threshold = log4net.Core.Level.Error; //append messages of Error or higher this.Evaluator = new log4net.Core.LevelEvaluator(Level.Off); //don't flush the buffer for any message, regardless of level I expect this would buffer 3 events of level Error or higher and deliver those events when the buffer is filled. However, I'm finding that the events are not buffered at all; instead, SendBuffer() is called immediately every time an error is logged. Is there a mistake in my configuration? Thanks

• "Cannot load ViewState" after dynamic control changed

  - by Emil D

  In my ASP.NET page I have to dynamically choose and load a custom control, depending on the selected value in a dropdownlist.However I encountered the following problem: When the parameters of the dynamically loaded control are changed, and then the selection in the dropdownlist is changed( thus forcing me to load a different dynamic control the next time the page reloads ), I end up with a "Cannot load ViewState" exception.I assume that this happens because the ViewState is trying to restore the parameters of the old control and it doesn't find it. So , is there any way to stop the viewstate from attempting to restore the state of the non-existig control?

• NSColor, 10.6 and Gamma 2.2

  - by Stephen Blinkhorn

  With Snow Leopard the default gamma changed from 1.8 to 2.2. I happen to be working on a few Mac apps that use a very dark custom colour scheme provided by Cocoa. On 10.5 it looks fine but on 10.6 with the new gamma it's much darker and really hard on the eyes. The colour scheme is defined using numerous [NSColor colorWithCalibratedRed:green:blue:alpha:] objects within a theme class. Is there any way to 'convert' an NSColor object so that it displays on 10.6 exactly as it would on 10.5 with the old 1.8 gamma? I know this can be achieved globally from within System Preferences but that's not what I'm after.

• Is there a standard format string in ASP.NET to convert 1/2/3/... to 1st/2nd/3rd...?

  - by Dr. Monkey

  I have an integer in an Access database, which is being displayed in ASP.NET. The integer represents the position achieved by a competitor in a sporting event (1st, 2nd, 3rd, etc.), and I'd like to display it with a standard suffix like 'st', 'nd', 'rd' as appropriate, rather than just a naked number. An important limitation is that this is for an assignment which specifies that no VB or C# code be written (in fact it instructs code behind files to be deleted entirely). Ideally I'd like to use a standard format string if available, otherwise perhaps a custom string (I haven't worked with format strings much, and this isn't high enough priority to dedicate significant time to*, but I am very curious about whether there's a standard string for this). (* The assignment is due tonight, and I've learned the hard way that I can't afford to spend time on things that don't get the marks, even if they irk me significantly.)

• How to extend the Turbogears 2.1 login functionality

  - by Marc

  I'm using Turbogears 2.1 and repoze.who/what and am having trouble figuring out how to extend the basic authentication functionality. I am essentially attempting to require users to activate their account via an emailed link before they can login. If they try to login without activating their account, I want to display an appropriate error message. The default Turbogears functionality simply displays one message for all errors. I created my own authentication plugin which works fine. It won't allow users to login if they have not activated their account. However, the problem comes when I try to create the form and display custom error messages. How can I go about doing this? Thanks

• Website with Microsites & Blog - recommendations

  - by pingu

  Hi guys, I'm in the process of scoping a solution for an events organisation. Their main website features information about them and blog entries etc, but they hold major events which require microsites (domain.com/event). The microsites all have a different look-and-feel, different nav structure, and custom content-managed components. The one thing that's common across everything is the blog - it will have a category for each event under which users can post. The main site will display all blog posts, but the microsites will only display posts for their category. How would you guys implement this? The solution needs to be PHP, and my initial thought was CodeIgniter but if possible I'd like to avoid building the blog functionality - so I guess I could integrate it with EE or Wordpress. If anyone has any other suggestions they would be most appreciated.
