• visual c# 2008 database application examples

  - by Omar

  hi, i just have a few weeks programming with vc# (2008) and i'm trying to build an application (winforms) and i have the following problem... i need my application to work with and without connection to the mssql database, this sounds like piece of cake for our friend DataSet right? i can persist the data as XML or binary until i can reach the database and the DataSet will magically sync; all without bothering the user. The problem is... the few books i have read just mention that logic like a fairy tale but dont give any practical example of how to do it, can you point me to one example/demo/whatever i can read or download of an application with (equal or) similar logic?

• Need help using ThemeRoller

  - by Music Magi

  Hi - I'm using DataTables to dress up a table I'm using to display XML results based on an XSL transformation. I have everything working from a technical sense (paging, sorting, filtering), but I'm trying to figure out to use a ThemeRoller theme to make it look like they have on their website. So far, I have added the following file to my project with its reference: <link type="text/css" href="css/custom-theme/jquery-ui-1.8.7.custom.css" rel="stylesheet"/> and enabled ThemeRoller themes using the following as per the DataTables website: $(document).ready(function() { $('#mainTable').dataTable( { "bJQueryUI": true, "sPaginationType": "two_button" }); }); The table gets styled, but it doesn't look right with the header rows being too wide and things being on multiple lines that should be on one line. Any indication as to what I'm doing wrong? Thanks very much in advance.

• Managing changes in memory-based data format

  - by kamziro

  So I've been using a compact data type in c++, and saving from memory or loading from the file involves just copying the bits of memory in and out. However, the obvious drawback of this is that if you need to add/remove elements on the data, it becomes kind of messy. There's also problems with versioning, suppose you distribute a program which uses version A of the data, and then the next day you make version B of it, and then later on version C. I suppose this can be solved by using something like xml or json. But suppose you can't do that for technical reasons. What is the best way to do this, apart from having to make different if cases etc (which would be pretty ugly, I'd imagine)

• Relative XPath selection using XmlNode (c#)

  - by maxp

  Say i have the following xml file: <a> <b> <c></c> </b> <b> <c></c> </b> </a> var nodes = doc.SelectNodes("/a/b"); will select the two b nodes. I then loop these two nodes suchas: foreach (XmlNode node in nodes) { } However, when i call node.SelectNodes("/a/b/c"); It still returns both values and not just the descendants. Is it possible to select nodes only descening from the current node?

  - by NemeSys

  I'm developing an iOS app with Twitter features. To do that I'm using SA_OAuthTwitterEngine and MGTwitterEngine wrappers. I've followed this post. I'm trying to retweet a tweet from the followed user timeline. This is what I send/receive: 2012-04-12 18:34:00.291 Project[13605:207] INFO -> Twitter URL: https://api.twitter.com/1/statuses/retweet/190459190869753856.xml 2012-04-12 18:34:00.292 Project[13605:207] INFO -> retweet response: 0AFF2EF9-6BCC-4B1E-B65A-02BD24A38C18 Here I pass to the API the id field of the selected tweet which I want to retweet. But after execute the method, the retweeted doesn't appears in the user timeline, where I'm getting the user tweets and tweets retweeted by user. What I'm loosing here? According with this the request to the Twitter API is ok. And I've checked the app permissions setted in twitter and have all: read/write and direct messages. Thanks.

• How to check value of stored procedure output parameter

  - by Anna T

  I have a stored procedure that: A. inserts some rows into a "table variable" based on some joins B. selects all values from column x from that table into a string with comma separated values C. selects all from the "table variable" If I execute the procedure like this: EXEC CatalogGetFilmDetails2 2,111111; a table is returned as instructed per step C above. How can I execute it so that also the output parameter value is displayed? (see point B above). I need to check if it's calculated properly. And since the second parameter is of output type, meaning it's calculated inside the procedure, why is it mandatory to specify a value for it when executing the procedure? I normally use a random value for it, it anyway doesn't matter/impact the result. On the other hand if I try to execute it without the output parameter, it returns an error) Thank you very much! This is how the procedure starts: CREATE PROCEDURE CatalogGetFilmDetails2 (@FilmID int, @CommaSepString VARCHAR(50) OUTPUT) AS And this is how @CommaSepString is calculated: SELECT @CommaSepString = STUFF((SELECT ', ' + Categ FROM @Filme1 FOR XML PATH('')), 1,1,'')

• Randomly generate sound from onClick and onShake events?

  - by Aaron

  I've literally looked everywhere on the net and found very little clarification on how to do this. Pretty much, I have 8 sound files laid out in an array.xml file and I need to play a randomly chosen file ONCE per or onClick or onShake. First off, what technique should I use to achieve this? ARRAY-RANDOM- STRING-PLAY? RANDOM INT-PLAY? RANDOM INT-STRING-PLAY? Any kind of direction will help greatly cause I'm almost 3 weeks worth of research into this. *NOTE: MediaPlayer mp = MediaPlayer.create(JelloMan.this, R.raw.sound) ...is what I'm stuck on being you can't replace the "R.raw" part with a string...

• FORMSOF Thesaurus in SQL Server

  - by Coolcoder

  Has anyone done any performance measures with this in terms of speed where there is a high number of substitutes for any given word. For instance, I want to use this to store common misspellings; expecting to have 4-10 variations of a word. <expansion> _{administration} _{administraton} _aministraton </expansion> When you run a fulltext search, how does performance degrade with that number of variations? for instance, I assume it has to do a separate fulltext search performing an OR? Also, having say 20/30K entries in the Thesaurus xml file - does this impact performance?

• What are the typical reasons Javascript developed on Firefox fails on IE?

  - by karlthorwald

  I developed some javascript enhanced pages that run fine on recent Firefox and Safari. I missed to check in Internet Explorer, and now I find the pages don't work on IE 6 and 7 (so far). The scripts are somehow not executed, the pages show as if javascript wasn't there, although some javascript is executed. I am using own libraries with dom manipulation, from YUI 2 I use YUI-Loader and the XML-Http-Request, and on one page I use "psupload", which depends on JQuery. I am installing Microsoft Script Editor from Office XP and will now debug. I will also write specific tests now. What are the typical failing points of IE? What direction I can keep my eyes open. I found this page, which shows some differences: http://www.quirksmode.org/compatibility.html Can you from your experience name some typical things I should look for first? I will also ask more questions here for specific tasks later, but for now I am interested in your experience why IE usually fails on scripts that run fine in Firefox

• Dynamically append number to PDF or make submit button change its URL based on that number.

  - by jamone

  I'm serving up PDFs from a SQL db and presenting them in the browser. I'm trying to figure out a way to embed a number in the PDF dynamically that is the recordID for that PDFs SQL record so that when the user hits the submit button and the form submits its XML data to my submission page I can tell which PDF this is. If there is some way of changing the submission URL on the fly then I could do a query string to pass my self the recordID. I'm not generating the PDF in code, its being created by hand and then uploaded to my site.

• Adding subview, gets delayed?

  - by user289510

  Hi, i didn't really know how to title this question, but here's a thing that really kills me: In my app i have a UITableView, UISegmentedControl and UINavigationBar. Once UISegmentedControl gets one of its segments selected i want to show a UIActivityIndicatorView on the UINavigationBar and then parse an xml file and present the results in a table. Everything works almost as i want it to, except one thing, the activity indicator view gets added to the uinavigationbar after the parser finishes, even though the method showLoading that adds UIIndicatorView to UINavigationBar gets before parser is initialised. Can anyone explain it? is there something i might be missing? maybe the ui needs to get redrawn? thanks peter

• Add a Carriage Return to the Output of an XSL Transformation

  - by dsrekab

  I am trying to use XSLT to convert an XML document to a text file and the text of the document looks fine. However, I need to add a carriage return after the end of each line (NOT A CRLF) and I seem to be failing in every attempt. I have tried adding just a CR at the end of the line like this: <xsl:text>&#xD;</xsl:text> I have tried changing my media-type to string, I have tried to add the disable-output-escaping attribute to the text element, but it always adds a CRLF. This is on a Windows OS and I know that Windows uses CRLF for a new line, but I would have thought you could override that if you said to specifically use only the CR or the LF (e.g. VB.net's VBCR or VBLF). Does anyone know if it is possible to only output a CR with XSLT? Thanks in advance.

• Is there a way to programmatically extract the feed of a podcast from the iTunes page?

  - by J. Pablo Fernández

  From an iTunes page, like http://itunes.apple.com/us/podcast/this-week-in-tech-mp3-edition/id73329404, is there a way to extract the corresponding feed address? In this case it would be http://leoville.tv/podcasts/twit.xml. I know that if you open on iTunes you can extract it manually, but I want to do it programmatically. There's a link to the website of the podcast, but it may not be accurate. In this case it points to a web site with 20 podcasts on it.

• Regular expressions and matching URLs with metacharacters

  - by James P.

  I'm having trouble finding a regular expression that matches the following String. Korben;http://feeds.feedburner.com/KorbensBlog-UpgradeYourMind?format=xml;1 One problem is escaping the question mark. Java's pattern matcher doesn't seem to accept \? as a valid escape sequence but it also fails to work with the tester at myregexp.com. Here's what I have so far: ([a-zA-Z0-9])+;http://([a-zA-Z0-9./-]+);[0-9]+ Any suggestions? Edit: The original intent was to match all URLs that could be found after the first semi colon.

• Windows Azure access POST data

  - by Mohamed Nuur

  Ok, so I can't seem to find decent Windows Azure examples. I have a simple hello world application that's based on this tutorial. I want to have custom output instead of JSON or XML. So I created my interface like: [ServiceContract] public interface IService { [OperationContract] [WebInvoke(UriTemplate = "session/create", Method = "POST")] string createSession(); } public class MyService : IService { public string createSession() { // get access to POST data here: user, pass string sessionid = Session.Create(user, pass); return "sessionid=" + sessionid; } } For the life of me, I can't seem to figure out how to access the POST data. Please help. Thanks!

• Inconsistent Loading Times for GeoRSS Overlay Between Firefox and IE

  - by Mark Fruhling

  I have a very simple page built to display a map and overlay a line based on points in a GeoRSS XML file. Here is the publicly accessible file. http://68.178.230.189/georssimport.html Firefox is loading in about 5 secs, which is expected because there are a lot of points to map, but IE (6 & 7) is taking upwards of 45 secs to a minute. What can I do to diagnose what is going on? What is a tool that will show me what is going on? (i.e. Firebug for IE) Thanks, Mark

• Android Template Application?

  - by stormin986

  I have built an application that I want to use as the foundation for a few other variants. The variants will come from assets / resource files and a unique AndroidManifest.xml. However, I want to be able to leave all the application code alone (modifying the package of all my classes, etc). I'm having a hard time figuring out how to do so. My first thought was to simply have my main application in its own package, and then specify the specific application package in the manifest. However, this gives me issues with the generated R.java class, since it is generated to be in the main application's package. Anyone have any thoughts on how to accomplish this? To have a code baseline, and the application variants happen in resources/assets and the manifest?

• Best way to get an Application Context into a static method in Android

  - by Slapout

  I'm working on an Android application that has several Activities. In it I have a class with several static methods. I would like to be able to call these methods from the different Activities. I'm using the static methods to load data from an xml file via a XmlResourceParser. To create a XmlResourceParser requires a call on the Application Context. So my question is, what is the best way to get a reference to the Application Context into the static methods? Have each Activity get it and pass it in? Store it somehow in a global variable?

• WCF - (Custom) binary serialisation.

  - by Barguast

  I want to be able to query my database over the web, and I am wanting to use a WCF service to handle the requests and results. The problem is that due to the amount of data that can potentially be returned from these queries, I'm worried about how these results will be serialised over the network. For example, I can imagine the XML serialisation looking like: <Results> <Person Name="Adam" DateOfBirth="01/02/1985" /> <Person Name="Bob" DateOfBirth="04/07/1986" /> </Results> And the binary serialisation containing types names and other (unnecessary) metadata. Perhaps even the type name for each element in a collection? o_o Ideally, I'd like to perform the serialisation of certain 'DataContract'-s myself so I can make it super-compact. Does anyone know if this is possible, or of any articles which explain how to do custom serialisation with WCF? Thanks in advance

• How to use custom color for each textview in listview that extends SimpleAdapter in Android ?

  - by mob-king

  I have a listview with custom rows and that extends SimpleAdapter. Each row consist of two linear layouts : 1st having two textviews of which one is hidden in horizontal orientation, second having two textviews in horizontal orientation. Now depending on the value in hidden textview , I want to setcolor for the remaining items for the row. To put it as simple: each listview item has some custom colors the value of which comes from the hidden field. I have done this by overriding getview() for the simpleadapter and returning view for each, but this makes list very slow to render (and that I think is obvious as so much of work for each view before showing it). Can I do this in some more efficient way ? like making views and then add up to list instead of using xml layout maybe one solution OR any other ? Any help ? Thanks.
