• Convert Chinese character .wav song into .mp3 or .wma on English OS

  - by Jack

  I have bunch of Chinese .wav files on my hard disk that I'm trying to convert into .mp3 with Audacity but it appear that Audacity can not read Chinese character songs but the .wav file display correctly on my 32 bits Win7 Ultimate(English) pc. I have to rename these Chinese character songs into English file name in order to convert them. Does anyone know if there is any software (prefer open source) that will take Chinese character file name(.wav) and convert it into .mp3 without renaming the file?

• How can I update only certain fields in a Django model form?

  - by J. Frankenstein

  I have a model form that I use to update a model. class Turtle(models.Model): name = models.CharField(max_length=50, blank=False) description = models.TextField(blank=True) class TurtleForm(forms.ModelForm): class Meta: model = Turtle Sometimes I don't need to update the entire model, but only want to update one of the fields. So when I POST the form only has information for the description. When I do that the model never saves because it thinks that the name is being blanked out while my intent is that the name not change and just be used from the model. turtle_form = TurtleForm(request.POST, instance=object) if turtle_form.is_valid(): turtle_form.save() Is there any way to make this happen? Thanks!

• How to match data between columns to do the comparasion

  - by NCC

  I do not really know how to explain this in a clear manner. Please see attached image I have a table with 4 different columns, 2 are identical to each other (NAME and QTY). The goal is to compare the differences between the QTY, however, in order to do it. I must: 1. sort the data 2. match the data item by item This is not a big deal with small table but with 10 thousand rows, it takes me a few days to do it. Pleas help me, I appreciate. My logic is: 1. Sorted the first two columns (NAME and QTY) 2. For each value of second two columns (NAME and QTY), check if it match with first two column. If true, the insert the value. 3. For values are not matched, insert to new rows with offset from the rows that are in first two columns but not in second two columns

• Passing through lists from jQuery to the service

  - by thedixon

  I'm sure I've done this in another solution, but I can't seem to find any solution as to do it again and wondered if anyone can help me... This is my WebAPI code: public class WebController : ApiController { public void Get(string telephone, string postcode, List<Client> clients) { } } And, calling this from jQuery: function Client(name, age) { this.Name = name; this.Age = age; } var Clients = []; Clients.push(new Client("Chris", 27)); $.ajax({ url: "/api/Web/", data: { telephone: "999", postcode: "xxx xxx", clients: Clients } }); But the "clients" object always comes back as null. I've also tried JSON.stringify(Clients), and this is the same result. Can anyone see anything obvious I'm missing here?

• WCF host address question

  - by Estelle

  when I setup the wcf service on a web server, I set the end point address as <endpoint address="http://www.mydomin.com/clientname/happy.svc" binding="basicHttpBinding" name="happysvcbasic" contract="happysvc.Ihappysvc"> </endpoint> but when type in above address on a browser, I get a different host name, which is the internal server name, such as, To test this service, you will need to create a client and use it to call the service. You can do this using the svcutil.exe tool from the command line with the following syntax: svcutil.exe http://internalservername.domain/clientname/happy.svc?wsdl I tried to add the host/baseaddress tag, but make no difference, what I missed? thanks for help.

• Rails - undefined method `name' for nil:NilClass

  - by sscirrus

  Hi guys, Quick question. Here is my code: #routes map.resources :customers, :has_many => [:addresses, :matchings] map.connect ":controller/:action/:id" #url path: http://127.0.0.1:3000/customers/index/3 #customers controller def index @customer = Customer.find(params[:id]) end #customers view/index.html.erb ... <%= @customer.name %> ... Error: undefined method `name' for nil:NilClass. Here's my reasoning. The parameter :id is coming from my url path (i.e. we're looking for customer #3 in the above path). @customer should find that array easily, then @customer.name should produce the name, but apparently @customer is blank. Why? I assume the problem is that I'm not producing an array in my controller?

• Would this rollback/stop all records from inserting?

  - by chobo2

  Hi I been going through this tutorial http://www.codeproject.com/KB/linq/BulkOperations_LinqToSQL.aspx and them make a SP like this CREATE PROCEDURE [dbo].[spTEST_InsertXMLTEST_TEST](@UpdatedProdData nText) AS DECLARE @hDoc int exec sp_xml_preparedocument @hDoc OUTPUT,@UpdatedProdData INSERT INTO TBL_TEST_TEST(NAME) SELECT XMLProdTable.NAME FROM OPENXML(@hDoc, 'ArrayOfTBL_TEST_TEST/TBL_TEST_TEST', 2) WITH ( ID Int, NAME varchar(100) ) XMLProdTable EXEC sp_xml_removedocument @hDoc Now my requirements require me to mass insert and mass update one after another. So first I am wondering can I merge those into one SP? I am not sure how it works with this OPENXML but I would think it would just be making sure that the XPath is right. Next what happens while it would be running this combined SP and something goes wrong. Would it roll back all the records or just stop and the records that happened before this event that crashed it would be inserted?

• numeric sort with NSSortDescriptor for NSFetchedResultsController

  - by edziubudzik

  I'm trying to numerically sort data that's displayed in a UITableView. Before that I used such a sort descriptor: sortDescriptor = [[NSSortDescriptor alloc] initWithKey:@"name" ascending:YES selector:@selector(caseInsensitiveCompare:)]; now I'd like to use block to sort this numerically like this: sortDescriptor = [[NSSortDescriptor alloc] initWithKey:@"name" ascending:YES comparator:^NSComparisonResult(id obj1, id obj2) { return [((NSString *)obj1) compare:(NSString *)obj2 options:NSCaseInsensitiveSearch | NSNumericSearch]; }]; but it sorts the data incorectly causing conflict with section names in NSFetchedResultsController. So I tryed to immitate the old sorting with a comparator block - just to be sure that the problem is not caused by numeric comparison. The problem is that those lines: sortDescriptor = [[NSSortDescriptor alloc] initWithKey:@"name" ascending:YES comparator:^NSComparisonResult(id obj1, id obj2) { return [((NSString *)obj1) caseInsensitiveCompare:(NSString *)obj2]; }]; also cause the same error and I don't see why they won't sort the data in the same way the first method did... Any ideas?

• how to call array values based on the main id they linked to?

  - by veronica george

  In page one, $add_id2=implode(',',$add_id); //result is 1,4 $item_type2=implode(',',$item_type_2); //result is 8,16 $final_total2=implode(',',$final); //result is 150,430 I pass these values via URL to the page two and store them in session. $_SESSION['cart'][$car]= array ('car'=>$car, 'loc_1'=>$location, array ( 'addon_id'=>$a_id, 'item_type'=>$item_type2, 'final_total'=>$final_t ) ); I call them like this, foreach($_SESSION['cart'] as $cart=>$things) { //display main array value like car id and location id echo $cart; foreach($things as $thing_1=>$thing_2) { foreach($thing_2['addon_id'] as $thi_2=>$thi_4) { //to display addons item for the car id //this is the id for each addon under the above car //echo $thi_2; //this is to echo addon id $thi_4; } } } The above loop works . the addon items array loops through inside main array which is car. If there were two addon items chosen then the addon array will loop twice. Now al I need to do is, How to make $item_type2 and $final_total2 display the value according to the addon id? PS: Same addon items can be chosen multiple times. They are identified uniquely by id(//echo $thi_2;). Thanks.

• Getting list of fields back from 'use fields' pragma?

  - by makenai

  So I'm familiar with the use fields pragma in Perl that can be used to restrict the fields that are stored in a class: package Fruit; use fields qw( color shape taste ); sub new { my ( $class, $params ) = @_; my $self = fields::new( $class ) unless ref $class; foreach my $name ( keys %$params ) { $self->{ $name } = $params->{ $name }; } return $self; } My question is.. once I've declared the fields at the top, how I can get the list back.. say because I want to generate accessors dynamically? Is keys %FIELDS the only way? Secondarily, is there a more efficient way to pre-populate the fields in the constructor than looping through and assigning each parameter as I am above? Thanks!

• What is the difference between as="element()+" and as="element()*" in XSL?

  What is the difference between using as="element(data)+" and as="element(data)" in xsl:variable. The below XSL solution works if use "+" but not when i use "". Can some one clarify. XSL code: <xsl:variable name="insert-data" as="element(data)+"> <xsl:for-each select="$insert-file/insert-data/data"> <xsl:sort select="xsd:integer(@index)"/> <xsl:variable name="index" select="xsd:integer(@index)" /> <xsl:variable name="nodeName" select="@nodeName" /> <data nodeName="{$nodeName}" index="{@index}" text-id="{$main-root/*//*[@id=$nodeName]/text()[sum((preceding::text(), .)/string-length(.)) ge $index]/generate-id(.)}"> <xsl:copy-of select="node()"/> </data> </xsl:for-each>

• Setting Image.Source doesn't update when loading from a resource.

  - by ChrisF

  I've got this definition in my XAML: <Image Name="AlbumArt" Source="/AlbumChooser2;component/Resources/help.png" /> The image is display OK on startup. In my code I'm looking for mp3's to play and I display the associated album art in this Image. Now if there's no associated image I want to display a "no image" image. So I've got one defined and I load it using: BitmapImage noImage = new BitmapImage( new Uri("/AlbumChooser2;component/Resources/no_image.png", UriKind.Relative)); I've got a helper class that finds the image if there is one (returning it as a BitmapImage), or returns null if there isn't one: if (findImage.Image != null) { this.AlbumArt.Source = findImage.Image; // This works } else { this.AlbumArt.Source = noImage; // This doesn't work } In the case where an image is found the source is updated and the album art gets displayed. In the case where an image isn't found I don't get anything displayed - just a blank. I don't think that it's the setting of AlbumArt.Source that's wrong, but the loading of the BitmapImage. If I use a different image it works, but if I recreate the image it doesn't work. What could be wrong with the image?

• Using variables within Attributes in C#

  - by tehp

  We have some Well-Attributed DB code, like so: [Display(Name = "Phone Number")] public string Phone { get; set; } Since it is quite generic we'd like to use it again, but with a different string in the Name part of the attribute. Since it's an attribute it seems to want things to be const, so we tried: const string AddressType = "Student "; [Display(Name = AddressType + "Phone Number")] public string Phone { get; set; } This seems to work alright, except that having a const string means we can't overwrite it in any base classes, thereby removing the functionality that we originally were intending to add, and exposing my question: Is there a way to use some sort of variable inside of an attribute so that we can inherit and keep the attribute decorations?

• Is there a way to include commas in CSV columns without breaking the formatting?

  - by editor

  I've got a two column CSV with a name and a number. Some people's name use commas, for example "Joe Blow, CFA." This comma breaks the CSV format, since it's interpreted as a new column. I've read up and the most common prescription seems to be replacing that character, or replacing the delimiter, with a new value (e.g. "this|that|the, other"). I'd really like to keep the comma separator (I know excel supports other delimiters but other interpreters may not). I'd also like to keep the comma in the name, as "Joe Blow| CFA" looks pretty silly. Is there a way to include commas in CSV columns without breaking the formatting, for example by escaping them?

• Problem with NHibernate and saving - NHibernate doesn't detect changes and uses old values.

  - by Vilx-

  When I do this: Cat x = Session.Load<Cat>(123); x.Name = "fritz"; Session.Flush(); NHibernate detects the change and UPDATEs the DB. But, when I do this: Cat x = new Cat(); Session.Save(x); x.Name = "fritz"; Session.Flush(); I get NULL for name, because that's what was there when I called Session.Save(). Why doesn't NHibernate detect the changes - or better yet, take the values for the INSERT statement at the time of Flush()?

• CSS - Why is this invisible margin being applied to my <a> tag css-button?

  - by Kenny Bones

  I was having trouble with two types of buttons. It was a form button and a css button basically. And I was advised that the css button whould use display:inline-block; This made the whole a href tag actually look like a button. But this invisible margin seems to be screwing up something. I tried separating them into separate css classes, but oddly, applying a real margin to the css button gives an additional margin as well. What's causing this? You can easily see it here (low graphics): www.matkalenderen.no Basically, code looks like this: <input type="submit" value="Logg inn" class="button_blue" alt="ready to login"> <a class="button_css_red" href="access.php">Glemt passord</a> CSS .button_red, .button_blue, .button_css_red, .button_css_blue { background-image:url("../img/sprite_buttons.png"); background-repeat:no-repeat; border: none; color:#FFFFFF; display:inline-block; display:inline-block; font-size:12px; height:27px; width:98px; } .button_css_red, .button_css_blue { margin-top:20px; }

• PHP export to text file - Only saving first line.

  - by wertz8090

  I'm trying to export some extracted $_POST information into a text file, however my code is only capturing the first variable and ignoring the rest. I'm saving the information to the text file in this manner: $values = "First Name: $fName\r\n"; $values .= "Last Name: $lName\r\n"; $values .= "Address: $address\r\n"; etc. This is the code I use to write to the text file: $fp = @fopen("person.data", "w") or die("Couldn't open person.data for writing!"); $numBytes = @fwrite($fp, $values) or die("Couldn't write values to file!"); @fclose($fp); Any ideas on why it would only save the first $values ($fName) variable but not the rest of them? It actually saves the first part of the $values string for all of them (so I see Last Name:, Address:, etc. on separate lines in the text file) but the called variables $lName and $address do not appear.
