• XML and .NET: How to replace specific node with many other ones loaded from raw xml data

  - by Entrase

  Let's suppose we have an element like this one in the main xml file: <group name="gr1" filename="groups/gr1.xml"/>. The second file gr1.xml contains something like this: <item name="i1">Item one</item> <item name="i2">Item two</item> <item name="i3">Item three</item> Note that there is no XML declaration in gr1.xml, just plain items without single parent node. So… Which is the best way to replace <group/> with its <item/>s? I have already tried some things like manual enclosing of gr1.xml content into a single node with XML declaration and loading it into XmlDocument, but it doesn't look like a good solution.

• Do iphone push notifications send the actual sound data to play, just a filename, or is it handled b

  - by SLC

  And, does it cache it locally? I ask because I am wondering if it's possible to change the sound of a push notification via SSH, replacing an app sound. My question is specifically about how the API for push notifications works. Does it send a .caf (aiff) binary file for the phone to play each time?

• How to make a data-bound combo box to display (like a DisplayMember) a syntetic string?

  - by Ivan

  I have a first name and a surname as separate columns in a table. If I bind a combo box to a query and set DisplayMember property to "Name" then each person a table is represented in a combo box by its name. How do I show each person's full name (built from concatenating 2 columns) in a single comb box item in this case?

• Avoid slowdowns while using off-site database

  - by Anders Holmström

  The basic layout of my problem is this: Website (ASP.NET/C#) hosted at a dedicated hosting company (location 1) Company database (SQL Server) with records of relevant data (location 2). Location 1 & 2 connected through VPN. Customer visiting the website and wanting to pull data from the company database. No possibility of changing the server locations or layout (i.e. moving the website to an in-office server isn't possible). What I want to do is figure out the best way to handle the data acces in this case, minimizing the need for time-expensive database calls over the VPN. The first idea I'm getting is this: When a user enters the section of the website needing the DB data, you pull all the needed tables from the database into a in-memory dataset. All subsequent views/updates to the data is done on this dataset. When the user leaves (logout, session timeout, browser closed etc) the dataset gets sent to the SQL server. I'm not sure if this is a realistic solution, and it obviously has some problems. If two web visitors are performing updates on the same data, the one finishing up last will have their changes overwriting the first ones. There's also no way of knowing you have the latest data (i.e. if a customer pulls som info on their projects and we update this info while they are viewing them, they won't see these changes PLUS the above overwriting issue will arise). The other solution would be to somehow aggregate database calls and make sure they only happen when you need them, e.g. during data updates but not during data views. But then again the longer a pause between these refreshing DB calls, the bigger a chance that the data view is out of date as per the problem described above. Any input on the above or some fresh ideas would be most welcome.

  It looks like they are converted to regular date types in the generated proxy object. I'd like to optionally pass null values for these dates. Other than switching to WCF (no time to learn it right now), what is the best way to handle this situation. It looks like I also cannot pass NULLABLE date types.

• Split a table in Word without losing row title

  - by Shane Hsu

  Word has the feature to repeat title row of a table when a table is so long that it spans a bunch of pages. I need to categorize my data into several pages, and I did that by splitting the table and insert page split to put them all in a page of itself. So now I got several page of data, but only the first page has title row. Is there anyway else to do this beside manually adding the title row to all the other pages? Original data: _________________ | Cat. Data | | 1 * | | 1 * | | 1 * | | 1 * | | 1 * | | 1 * | | 2 * | | 2 * | | 2 * | | 2 * | | 3 * | |___3______*______| And then turn it into: _________________ | Cat. Data | | 1 * | | 1 * | | 1 * | | 1 * | | 1 * | |___1______*______| Next page _________________ | Cat. Data | | 2 * | | 2 * | | 2 * | |___2______*______| Next Page _________________ | Cat.

• Need to determine button clicked in a JQuery mobile popup and perform actions based thereon

  - by Clifford

  I am having a problem with a JQM popup. The popup has 3 buttons, and the action taken in the main program depends on which button is clicked. The code in the main program is run more than once and I am not sure why. The simple example below uses an alert to display which button on the popup was clicked. When the popup is called the first time, it works as hoped, the 2nd time, the alert is displayed twice, the 3rd time, the alert is displayed 3 times, etc. <html> <head> <meta name="viewport" content="width=device-width, initial-scale=1"> <link rel="stylesheet" href="css/jquery.mobile-1.3.2.min.css" /> <script type="text/javascript" charset="utf-8" src="cordova-2.6.0.js"></script> <script type="text/javascript" src="js/jquery-1.9.1.min.js"/></script> <script type="text/javascript" src="js/jquery.mobile-1.3.2.min.js"></script> <script> function doCustomDialog(text1,button1,button2,button3,callback) { $("#customDialog .customDialogDesc").text(text1); $("#customDialog .customDialogOption1").text(button1).on("click.customDialog", function(){ callback("option1"); }); $("#customDialog .customDialogOption2").text(button2).on("click.customDialog", function(){ callback("option2"); }); $("#customDialog .customDialogOption3").text(button3).on("click.customDialog", function(){ callback("option3"); }); $("#customDialog").popup("open"); } </script> </head> <body> <div data-role="page" id="mainPage"> <div data-role="content"> <INPUT type="button" id="confirm" value="Save data" /> <div data-role="popup" id="customDialog" data-title="Are you sure?" class="ui-content"> <p class ="customDialogDesc">???</p> <a href="#" class ="customDialogOption1" data-role="button" data-theme="b" data-rel="back">Yes</a> <a href="#" class ="customDialogOption2" data-role="button" data-theme="b" data-rel="back">No</a> <a href="#" class ="customDialogOption3" data-role="button" data-theme="b" data-rel="back">Cancel</a> </div> </div> </div> <script> $("#mainPage").on("pageshow", function(e) { $("#confirm").click(function() { doCustomDialog("A similar record already exists.

• Is there a better way to deal with reserved characters when parsing XML/JSON data on the iPhone?

  - by Charles S.

  The following code works, but it's ugly and creates a bunch of autoreleased objects. I'm using similar code for parsing reserved HTML characters as well (for quotes, & symbols, etc). I'm just wondering... Is there a cleaner way? NSString *result = [[NSString alloc] initWithString:userInput]; NSString *result2 = [result stringByReplacingOccurrencesOfString:@"#" withString:@"\%23"]; NSString *result3 = [result2 stringByReplacingOccurrencesOfString:@" " withString:@"\%20"]; formatted = [[result3 stringByReplacingOccurrencesOfString:@"&" withString:@"\%26"] retain]; [result release];

• Is there a way to combine streaming data retrieval with hibernate?

  - by Steve B.

  For the purposes of handling very large collections (and by very large I just mean "likely to throw OutOfMemory exception"), it seems problematic to use Hibernate because normally collection retrieval is done in a block, i.e. List values=session.createQuery("from X").list(), where you monolithically grab all N-million values and then process them. What I'd prefer to do is to retrieve the values as an iterator so that I grab 1000 or so (or whatever's a reasonable page size) at a time. Apart from writing my own iteration (which seems like it's likely to be re-inventing the wheel) is there a hibernate-native way to handle this?
