  • Haskell - Parsec Parsing <p> element

    - by Martin
    I'm using Text.ParserCombinators.Parsec and Text.XHtml to parse an input like this: This is the first paragraph example\n with two lines\n \n And this is the second paragraph\n And my output should be: <p>This is the first paragraph example\n with two lines\n</p> <p>And this is the second paragraph\n</p> I defined: line= do{ ;t<-manyTill (anyChar) newline ;return t } paragraph = do{ t<-many1 (line) ;return ( p << t ) } But it returns: <p>This is the first paragraph example\n with two lines\n\n And this is the second paragraph\n</p> What is wrong? Any ideas? Thanks!

  • Image reflection in Silverlight 4

    - by Phani Kumar PV
    I am developing a product scrolling feature where products info( product image, Name, price)will be shown side by side horizontally. i need to show the image of the product and also its reflection. under the reflected image i need to show the Prod Name and its price. The problem here is i dont want to show the complete reflected image. the oputput should be something like this Image Height-100% Reflected Image Height-20% Product name Product Price The above pattern will repeat horizontally. I am able to get the desired output with some problem. The reflected image is shown up with hieght 100% and the sapce between the actual image and product name is very high. My reflected image should be a rotated image of the actual image and only half part of the actual image should be shown. Any pointers even is highly appreciated

  • How to Practically Split Values from CSV File into MySQL Database

    - by Ryan
    Let's suppose I have the following line in a CSV file (I removed the header row in this example): "500,000",2,50,2,90000 I have a PHP script read the CSV file, break the file into individual lines, and store each line in an array called $linearray. Then, I use a foreach loop to look at each line individually. Within the foreach loop, I break the line into separate variables using the following function: $line = str_replace("'","\'",$line); From here, I insert the values into separate columns within a MySQL database. The script works. The values are inserted into a database, but I run into a problem. I want: "500,000" | 2 | 50 | 2 | 90000 But I get this: "500 | 000" | 2 | 50 | 2 | 90000 The script isn't smart enough to understand it should skip commas within quotation marks. Do you know how I can alter my script to make sure I get the output I'm looking for? Thanks.

  • How to handle model state errors in ajax-invoked controller action that returns a PartialView

    - by Robert Koritnik
    I have a POST controller action that returns a partial view. Everything seems really easy. but. I load it using $.ajax(), setting type as html. But when my model validation fails I thought I should just throw an error with model state errors. But my reply always returns 500 Server error. How can I report back model state errors without returning Json with whatever result. I would still like to return partial view that I can directly append to some HTML element. Edit I would also like to avoid returning error partial view. This would look like a success on the client. Having the client parse the result to see whether it's an actual success is prone to errors. Designers may change the partial view output and this alone would break the functionality. So I want to throw an exception, but with the correct error message returned to the ajax client.

  • How does one pre-populate a Python Formish form?

    - by Jace
    How does one pre-populate a Formish form? The obvious method as per the documentation doesn't seem right. Using one of the provided examples: import formish, schemaish structure = schemaish.Structure() structure.add( 'a', schemaish.String() ) structure.add( 'b', schemaish.Integer() ) schema = schemaish.Structure() schema.add( 'myStruct', structure ) form = formish.Form(schema, 'form') If we pass this a valid request object: form.validate(request) The output is a structure like this: {'myStruct': {'a': 'value', 'b': 0 }} However, pre-populating the form using defaults requires this: form.defaults = {'myStruct.a': 'value', 'myStruct.b': 0} The dottedish package has a DottedDict object that can convert a nested dict to a dotted dict, but this asymmetry doesn't seem right. Is there a better way to do this?

  • Multiplying char and int together in C part 2

    - by teehoo
    If I do the following: int c0 = CHAR_MAX; //8 bit int c1 = CHAR_MAX; //8-bit int i = c0*c1; //store in 32-bit variable printf("%d\n", i); //prints 16129 We can see that there is no problem with to 8-bit numbers being multiplied together, and producing a 32-bit output. However, if I do int i0 = INT_MAX; //32-bit int i1 = INT_MAX; //32 bit variable long long int ll = i0*i1; //store in 64-bit variable printf("%lld\n", ll); //prints 1..overflow!! In this case, two 32-bit variables were multiplied together, overflowed, and then were assigned to the 64-bit variable. So why did this overflow happen when multiplying the ints, but not the chars? Is it dependent on the default word-size of my machine? (32-bits)

  • Java NullPointerException when traversing a non-null recordset

    - by Tim
    Hello again - I am running a query on Sybase ASE that produces a ResultSet that I then traverse and write the contents out to a file. Sometimes, this will throw a NullPointerException, stating that the ResultSet is null. However, it will do this after printing out one or two records. Other times, with the same exact input, I will receive no errors. I have been unable to consistently produce this error. The error message is pointing to a line: output.print(rs.getString(1)); It appears to happen when the query takes a little longer to run, for some reason. The recordset returns thus far have been very small (4 to 7 records). Sometimes I'll have to run the app 3 or 4 times, then the errors will just stop, as though the query was getting "warmed up". I've run the query manually and there doesn't appear to be any performance problems. Thanks again!

  • Optimal way to generate list of PHP object properties with delimiter character, implode()?

    - by Kris
    I am trying to find out if there is a more optimal way for creating a list of an object's sub object's properties. (Apologies for the crude wording, I am not really much of an OO expert) I have an object "event" that has a collection of "artists", each artist having an "artist_name". On my HTML output, I want a plain list of artist names delimited by a comma. PHP's implode() seems to be the best way to create a comma delimited list of values. I am currently iterating through the object and push values in a temporary array "artistlist" so I can use implode(). That is the shortest I could come up with. Is there a way to do this more elegant? $artistlist = array(); foreach ($event->artists as $artist) { $artistlist[] = $artist->artist_name; } echo implode(', ', $artistlist);

  • Adding ivars to NSManagedObject subclass

    - by The Crazy Chimp
    When I create an entity using core data then generate a subclass of NSManagedObject from it I get the following output (in the .h): @class Foo; @interface Foo : NSManagedObject @property (nonatomic, retain) NSString *name; @property (nonatomic, retain) NSSet *otherValues; @end However, in my .m file I want to make use of the name and otherValues values. Normally I would simply create a couple of ivars and then add the properties for them as I required. That way I can access them in my .m file easily. In this situation would it be acceptable to do this? Would adding ivars to the .h (for name and otherValues) cause any unusual behaviour in the persistance & retrieval of objects?

  • 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!

  • Django: way to test what class a generic relation content_object is?

    - by bitbutter
    In my project I have a class, NewsItem. Instances of NewsItem act like a wrapper. They can be associated with either an ArtWork instance, or an Announcement instance. Here's how the NewsItem model looks: class NewsItem(models.Model): content_type = models.ForeignKey(ContentType) object_id = models.PositiveIntegerField() content_object = generic.GenericForeignKey('content_type', 'object_id') date = models.DateTimeField(default=datetime.datetime.now,) class Meta: ordering = ('-date',) def __unicode__(self): return (self.title()) In a template I'm dealing with a NewsItem instance, and would like to output a certain bunch of html it it's 'wrapping' an Artwork instance, and a different bunch of html if it's wrapping an Announcement instance. Could someone explain how I can write a conditional to test for this? My first naive try looked like this: {% if news_item.content_object.type=='Artwork' %}do this{% else %}do that{% endif %}

  • SOS: AudioFormat when writing to file in FreeTTS

    - by user330793
    Very annoying problem. I have developed a freeTTS application of the freetts class that write captured audio to file however I am having some very annoying problems. When setting the audio player to singlefileaudio player I try to also set the audioformat with my own default values for sampleRate, sampleSizeInBits, channels, signed and bigEndian. Now I access AudioPlayer.get methods to show these values in runtime just to ensure they are set to what I set them and they match those values. However when file writing completes and I check the properties of the resulting wave file, they are set to the audioPlayer default settings. Normally this will be fine except I have to read the files into another application which has fixed audio property settings so I always get a resulting output that sounds like am fast forwarding the sound and listening to it at the same time. Obviously because of the different sampling rates. I need help please. Thanx, Henry

  • Stringbuilder problem creating dynamic links

    - by wali
    Hi all, I'm having an issue creating a link like "<a href="javascript:window.open('www.microsoft.com');">Visit Microsoft</a> using stringbuilder. I am adding html to a panel dynamically and I am trying to create a popup link. The problem is that for some reason the link gets "mixed up". For example: Dim s As String sb.Append("<A HREF='javascript:void(0)' onclick='window.open(") sb.Append("'") sb.Append("Match.aspx?MatchID=") sb.Append(mt.MatchID) sb.Append("&batchid=") sb.Append(mb.batchID) sb.Append("')>") sb.Append("Match</A>") gives an output of : <a match.aspx?matchid="28840&amp;batchid=26596')" onclick="window.open(" href="javascript:void(0)">Match</a> I have no clue what I'm doing wrong, it even does this kind of crap for a regular string! Please help!

  • Python Daemon Subprocess not working at boot

    - by Adam Richardson
    I am attempting to write a python daemon that will launch at boot. The goal of the script is to receive a job from our gearman load balancing server and complete the job. I am using the python-daemon module from pypi (http://pypi.python.org/pypi/python-daemon/). The nature of the job that it is completing is converting images in the orf (olympus raw image format) to jpeg. In order to accomplish this an outside program is used, ufraw in this case. The problem comes in when I start the daemon at boot, if I launch from the shell it runs perfectly and completes the work. When it starts at boot it is unable to launch the subprocess command. commandString = '/usr/bin/ufraw-batch --interpolation=four-color --wb=camera --compression=100 --output="' + outfile + '" --out-type=jpg --overwrite "' + infile + '"' args = shlex.split(commandString) process = subprocess.Popen(args).wait() I am not sure what I am doing wrong. Thanks for any help.

  • Parsing a website

    - by Phenom
    I want to make a program that takes as user input a website address. The program then goes to that website, downloads it, and then parses the information inside. It outputs a new html file using the information from the website. Specifically, what this program will do is take certain links from the website, and put the links in the output html file, and it will discard everything else. Right now I just want to make it for websites that don't require a login, but later on I want to make it work for sites where you have to login, so it will have to be able to deal with cookies. I'll also want to later on have the program be able to explore certain links and download information from those other sites. What are the best programming languages or tools to do this?

  • help with array

    - by JohnWong
    You will write a program that evaluates the integral of sin(x) using the left-hand rectangle rule with 2000 subintervals, over 10 intervals. The intervals to test are [0, 1), [1, 2), …, [8, 9), [9, 10). You will declare an array of type double that can hold 10 elements, and you will use this array to hold all 10 results you get from evaluating each interval. I am in testing my code, what should be the output? For example, [0, 1)? Any idea? Thanks.
