• Blackberry JDE generating bad .jad file (does not match compiled .cod file)

  - by matkas

  I Have a BB application that gets compiled into 3 siblings cod file. ( actualy one cod fil contaning 3 sub cod files). app.cod |--app.cod |--app-1.cod |--app-2.cod which is normal. the jad refers to those 3 inner .cod files. Now I have add some feature to my app, it is getting a little bit bigger. the jad now refers to 4 inner .cod files. but there is still 3 inside the app.cod that is generated. so I now still have app.cod |--app.cod |--app-1.cod |--app-2.cod but with the jad refering to app.cod app-1.cod app-2.cod AND app-3.cod. what is wrong the my compiled program? is it a bug from the JDE? I am using JDE 4.5.

• Any ideas on how to implement a 'touchMoveOver' event in Javascript?

  - by gargantaun

  I'm faffing around with SVG, specifically for web content aimed at iPad users. I've created a little dial type thingy that I'm calling a "cheese board" that I'd like to use as an interface element. http://appliedworks.co.uk/files/times/SVGTests/raphael.html Clicking on a piece of cheese (to keep the analogy going) will do "something". That bit's easy. However, I'd like the user to be able to drag their finger around the 'cheese board', firing a new event (touchesMovedOver?) every time they their finger moves over a new piece of cheese. But I can't figure out how to do it since there's no 'mouseOver' equivalent for touch interfaces. If the whole thing was made of squares, I could have created some sort of 'rectContainsPoint' method to be called for every 'touchesMoved', but that approach wouldn't work here. If anyone has any idea about how something like this could be achieved, I'd love to hear it.

• Multi-Threading in .NET

  - by AIC

  Hi all.. I wrote this program, that is supposed to read about 5000 email address and send an pre-defined html mail. I am using the background worker component. The problem is this: I have wired up the method who is supposed to send the mail. But I am calling another method that is supposed to append the body html to the salutation, like public string GiveMeFullHtml(string personname) ... "Dear Mr. John Doe" + HTML ... It seems that when it hits this method call, operation completes. IUt only sends the first mail and completes. I think because the HTML string method is on another thread or sth like that. Can you give me a little insight. Do I have to get everything done in the very same method when using multi-threading? Thanks in advance

• Store html form on client or server while building?

  - by Brett

  Hi, I have a fairly complex html form enhanced via jquery. It has multiple tabs, within each one things like a html form builder, uploads, descriptions. There is lots of data, and as the user flicks around the various tabs I'm thinking of posting the data to the server. For example, the form builder, has about 10 properties for each field, as the user flicks between the various fields, an ajax request saves the current values, then loads a new set from the new field clicked on. When the user hits save, the idea is then on the server all these bits and pieces come together and become the live version (i may store them as a temp version while the user is working away). So I guess my question is, for complex forms where the same fields are re-used within the one form, does anyone attempt to save all this data locally and upload it in one hit or do most of you do little ajax post's and compile it all when the final save button is hit? b

• Toubleshooting mapkit performance

  - by brettr

  I'm plotting over 500 points on a map using mapkit. Zooming is a little jittery compared to the native google map app. I've discovered what is causing the slowness. I'm adding custom annotations so that I can later add different pin colors and buttons for detail views: - (MKAnnotationView *) mapView:(MKMapView *)mapView viewForAnnotation:(AddressNote *) annotation { MKPinAnnotationView *annView=[[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:@"currentlocation"]; annView.pinColor = MKPinAnnotationColorGreen; annView.animatesDrop=TRUE; annView.canShowCallout = YES; annView.calloutOffset = CGPointMake(-5, 5); return annView; } If I comment out the above code, everything works fine. Very smooth with zooming in/out. Should I be adding annotations differently to boost performance?

• Macros no longer working in VS2005

  - by NPVN

  I'm using VS2005 on Vista. I'm using some macros, but now they have suddenly stopped working. No error messages of any kind. I am not aware of having done anything that could trigger this. I have made sure that "Allow macros to run" is checked in Tools-Options-Addin/Macro Security. I have tried running the macros from a keyboard shortcut, from the Macro Explorer, and from the Macros IDE, all in vain: The little spinning icon displays shortly (<1 sec) and then disappears without the macro being executed. I have tried putting a breakpoint on the first line of the macro and then executing it from the main IDE, with no effect (the breakpoint isn't hit). I have tried the same from the Macro IDE: The state changes to "running", but the breakpoint isn't hit. I have to break the execution manually. Any ideas?

• Filtering A MySQL Result Set Based On The Return Value Of A Function

  - by Joshua

  I'm a SQL noob, and I need a little bit of help understanding the big picture of if it is possible, and if so how to go about filtering a result set based on the return value of a function which is passed one of the fields of the record. Let's say I have a table called "Numbers" with just one field: "Value". How could I correctly specify the following "pseudo-sql"?: SELECT Value FROM numbers WHERE IsPrime(Value)=true Can I accomplish such a thing, and if so, where/how do I put/store "IsPrime"? I'm using MySQL.

• Critiquing my first Python script

  - by tipu

  A little bit of background: I'm building an inverted index for a search engine. I was originally using PHP, but because of the amount of times I needed to write to disk, I wanted to make a threaded indexer. There's a problem with that because PHP is not thread safe. I then tried Java, but I ended up with at least 20 try catch blocks because of the JSON data structure I was using and working with files. The code was just too big and ugly. Then I figured I should pick up some Python because it's flexible like PHP but also thread safe. Though I'm open to all criticism, what I'd like to learn is the shortcuts that the Python language/library provides that I skipped over. This is a PHP-afide Python script because all I really did was translate the PHP script line by line to what I thought was it's Python equivalent. Thanks. http://pastebin.com/xrg7rf9w

• How do you authenticate user generated "apps" for your app?

  - by Brian Armstrong

  I'm think something like Facebook apps here. User generated pieces of code that people can write to interact with my app. I understand how an authenticated API works, but this seems a little more complicated because not only does the APP have to authenticate itself (with a regular api-key) but the USER using the app has to be authenticated somehow too, without giving the app free reign. I've been reading a bit here to see how FB does it: http://wiki.developers.facebook.com/index.php/How_Facebook_Authenticates_Your_Application And it looks like you have to pass a signature in addition to the api-key along with every call, but I'm having trouble wrapping my head around how this gets generated and used on the other end (my server). Figure there must be a simple explanation of this out there? Thanks! P.S. I'm building a Rails app if there are any applicable gems/plugins.

• Best method to compress JSON string in term of performance and compress radio

  - by Eric Yin

  For a JSON string, contains all kinds of settings, numbers, string etc. Total JSON string fairly fall into 10k~50K range. I want to compress it before save to database. So I wonder which compress method should I choose, I am using c# 4, I know I can choose gzip and deflate but the compression radio is not good (although speed is good). More specific, compress can be a little slow (since only once) but should be small. Decompress should be lighting fast since decompress happens lots. Please give some advice.

• how subsonic SP should return a value

  - by android.sm

  Hi all, I'm very much new to SubSonic and need a little guidance. Here, I want to know how my SP should return a value. Currently, when I execute it I simply pass an Int and it returns me a string value. Here is code: SubSonic SP: public static StoredProcedure GetQuote(int? CategoryId) { StoredProcedure sp = new StoredProcedure("GetQuote", DataService.GetInstance("Quotes Provider"), "dbo"); sp.Command.AddParameter("@CategoryId", CategoryId, DbType.Int32, 0, 10); return sp; } My Code: public bool GetQuote(int category, out string quote) { bool val = false; quote = ""; try { StoredProcedure sp = SPs.GetQuote(category); if (sp != null) { sp.Execute(); val = true; } } catch (Exception err) { throw err; } return val; } Thanks all

• How can I easily get a TextReader from an XDocument?

  - by Mark Seemann

  Given an XDocument instance, how can I easily get a TextReader that represents that instance? The best I've been able to come up with is something like this (where xml is an XDocument instance): var s = new MemoryStream(); var sw = new StreamWriter(s); xml.Save(sw); sw.Flush(); s.Position = 0; TextReader tr = new StreamReader(s); However, this seems a little clunky, so I was wondering if there's an easier way?

• C# assign char and char array to string?

  - by Bopha

  char character = 'c'; string str = null; str = character.ToString();//this is ok char[] arrayChar = { 'a', 'b', 'c', 'd' }; string str2 = null; str2 = string.Copy(arrayChar.ToString());//this is not ok str2 = arrayChar.ToString();//this is not ok. I'm trying to converting char array to string, but the last two attempts don't work. Other source I found and they have to create new string type, but I don't know why. Can someone give me little explaination, thanks.

• J2ME HTTPS Connection Problem: Certificate was issued by an unrecognized entity

  - by Mustafa

  I am developing a little J2ME application that will read our grades from our university's server. With Desktop Applications, It is fine, I can do it but in J2ME, it always gives me this error, even I use well-known services like HTTPS Google, I still get the same error. urlConn = (HttpsConnection) Connector.open("https://stars.bilkent.edu.tr/srs/ajax/login.php"); urlConn.setRequestMethod(HttpsConnection.POST); urlConn.setRequestProperty("Content-Type", "application/x-www-form-urlencoded"); o = urlConn.openOutputStream(); // Sending my POST requests to server input = urlConn.openDataInputStream(); In the last line I always get the error I mentioned above. What should I do about it?

• How to: WCF XML-RPC client?

  - by mr.b

  I have built my own little custom XML-RPC server, and since I'd like to keep things simple, on both server and client side, what I would like to accomplish is to create a simplest possible client (in C# preferably) using WCF. Let's say that Contract for service exposed via XML-RPC is as follows: [ServiceContract] public interface IContract { [OperationContract(Action="Ping")] string Ping(); // server returns back string "Pong" [OperationContract(Action="Echo")] string Echo(string message); // server echoes back whatever message is } So, there are two example methods, one without any arguments, and another with simple string argument, both returning strings (just for sake of example). Service is exposed via http. Aaand, what's next? :) P.S. I have tried googling around for samples and similar, but all that I could come up with are some blog-related samples that use existing (and very big/numerous) classes, which implement appropriate IContract (or IBlogger) interfaces, so that most of what I am interested is hidden below several layers of abstraction...

• javascript to launch only ONE window for a Java applet with a given URL

  - by Jonathan Dugan

  I need a javascript solution to launch only one window, with a Java Applet in it, for a given URL. I found a solution posted here on Stack Overflow - here: http://stackoverflow.com/questions/528671/javascript-window-open-only-if-the-window-does-not-already-exist But it doesn't seem to work .. I get Error: launchApplication.winrefs is undefined Line: 29 I can't seem to post the code in this little box and make it look right below, so the code (my working code, plus the solution from above) is here: http://pastie.org/833879 Where is the error? As I understand it, the hash or array or whatever I use to store the called references to the windows opened this way will be lost if the calling window is closed. Is there a way to make this work even if the calling window is closed and reopened? To basically ask the browser: "Do you have a window open with the following URL?" and if so, "What is the reference to that window?" (so I can raise it).

• Zedgraph textobj X location depends on text length?

  - by Tony_Henrich

  I have a Zedgraph textobj which I want to place always in the same x, y position (ASP.NET image). I noticed that the text doesn't always show in the same starting x position. It shifts depending on the text's length. I tried to have the text to have the same length by padding it with spaces. It helped a little but the result is not always consistent. I am using PaneFraction for coordType. What's the proper method to have a piece of text to always show in the same x position. I am using textobj as a title because the native title property always shows up centered and I need my title be left aligned to the graph.

• Ivy: Publishing all artefacts in a directory

  - by Dave Flowers

  I'm looking to move to Apache Ivy for dependency management on one of our existing projects. The project publishes many artefacts, and the artefacts it produces are likely to change in the future, so I don't want to enumerate all of the publications in the ivy.xml file -- I'd like Ivy to just publish all the files in a given directory. I considered auto-generating a list of the files built and using XSLT to insert it into the ivy.xml, but that seems a little cumbersome for what I'd expect to be a reasonably common requirement. Is there a better way to do this? Can Ivy pick up all the files in a directory and ignore the publications in the Ivy file? Or is there some way to get Ivy to use different files for publication and for fetching, so I can avoid having to use XSLT to merge the files.

• Where Are the Release Versions of ASP.Net AJAX 4.0 Templating Files?

  - by Lee Richardson

  I'm trying to get the production version of ASP.Net AJAX 4.0 Templating working and can't find the JavaScript files. With the beta version I needed to reference MicrosoftAjaxTemplates.js, MicrosoftAjaxAdoNet.js, and MicrosoftAjaxDataContext.js. I can get everything to work with the beta CDN versions (e.g. http://ajax.microsoft.com/ajax/beta/0911/MicrosoftAjaxTemplates.js). But for the life of me I can't find 1. The release CDN versions of these files or 2. Where to download the whole Release ASP.Net AJAX 4.0 JavaScript package. The files certainly are not listed on the ASP.Net AJAX 4.0 CDN at http://www.asp.net/ajaxlibrary/CDNAjax4.ashx. Maybe the files have been renamed? Theoretically this should be a rediculously easy question and I'm a little embarrased to even ask it on StackOverflow, but I've had no luck finding an answer on my own. Any help would be much appreciated. Thanks, - Lee

• Safe deployment of ASP.Net applications

  - by gatapia

  Hi All, I have an asp.net app that I want to deploy safely (with as little down time possible). I would love to do something like blue green deployment but without the need for a second web server. So, I know I can use load balancing, etc but I need a quick and cheap approach. I was thinking of doing something like: Setting up another website (copy of original) in IIS, currently I use host headers to direct traffic across sites). I could then view the new site locally until the site is totally online (due to NHibernate start up and various other high intensity tasks this takes a while). Once site 2 is totally started I would then change host headers around giving me a much much smaller down time. So my question is. Has anyone done anything like this? Will IIS restart my app pool or application when changing host headers (making this useless)? Any other options? Thanks for your help all. Guido

• How does one go about understanding GNU source code?

  - by Max Dwayne

  I'm really sorry if this sounds kinda dumb. I just finished reading K&R and I worked on some of the exercises. This summer, for my project, I'm thinking of re-implementing a linux utility to expand my understanding of C further so I downloaded the source for GNU tar and sed as they both seem interesting. However, I'm having trouble understanding where it starts, where's the main implementation, where all the weird macros came from, etc. I have a lot of time so that's not really an issue. Am I supposed to familiarize myself with the GNU toolchain (ie. make, binutils, ..) first in order to understand the programs? Or maybe I should start with something a bit smaller (if there's such a thing) ? I have little bit of experience with Java, C++ and python if that matters. Thanks!

• Recommendations for supporting both Oracle and MSSQL in the same ASP.NET app with NHibernate

  - by Hugo Zapata

  Our client wants to support both SQLServer and Oracle in the next project. Our experience comes from .NET/SQL Server platform. We will hire an Oracle developer, but our concern is with the DataAccess code. Will NHibernate make the DB Engine transparent for us? I don't think so, but i would like to hear from developers who have faced similar situations. I know this question is a little vague, because i don't have Oracle experience, so i don't know what issues we will find.

• Drupal Views pulling Data Fields

  - by askon

  I'm a little new to drupal but have been using things like devel module and theme developer to speed up the learning process. My question, is it possible to theme an entire views BLOCK from a single views tpl.php page OR even a preprocess? When I'm grabbing the $view object I can see results $node-result, it has all of the results, but it doesn't have all my views fields. I'm missing things like, node path, taxonomy titles and paths, etc. From my understanding, Drupal wants you to individually theme EACH output field. It seems rather superfluous to create so many extra templates when I've already got over HALF of my results coming through the $view object Would outputting node over field make this easier? Or am going in the wrong direction with $view-result? Thanks!

• Adding JTextField to a JPanel and showing them

  - by Davide Gualano

  I'm building a little app using Java and Swing in NetBeans. Using NetBeans design window, I created a JFrame with a JPanel inside. Now I want to dynamically add some jTextFields to the JPanel. I wrote something like that: Vector textFieldsVector = new Vector(); JTextField tf; int i = 0; while (i < 3) { tf = new JTextField(); textFieldVector.add(tf); myPanel.add(tf); //myPanel is the JPanel where I want to put the JTextFields i++; } myPanel.validate(); myPanel.repaint(); But nothing happens: when I run the app, the JFrame shows with the JPanel inside, but the JTextFields don't. I'm a total newbie in writing graphical Java apps, so I'm surely missing something very simple, but I can't see what.
