  • Parsing question

    - by j-t-s
    Hi All I have tried using several different parsers as advised by somebody but i don't believe that they'd be of any use for this particular situation. I have a file that looks like this: mylanguagename(main) { OnLoad(protected) { Display(img, text, link); } Canvas(public) { Image img: "Images\my_image.png"; img.Name: "img"; img.Border: "None"; img.BackgroundColor: "Transparent"; img.Position: 10, 10; Text text: "This is a multiline str#ning. The #n creates a new line."; text.Name: text; text.Position: 10, 25; Link link: "Click here to enlarge img."; link.Name: "link"; link.Position: 10, 60; link.Event: link.Clicked; } link.Clicked(sender, link, protected) { Link link: from sender; Message.Display: "You clicked link."; } } ... and I need to be able to parse that code above, so and convert it to a Javascript equivelent, (or JScript). Can somebody please help, or get me started in the right direction? Thanks

  • how to switch views according to command

    - by Veer
    I've a main view and many usercontrols. The main view contains a two column grid, with the first column filled with a listbox whose datatemplate consists of a usercontrol and the second column filled with another usercontrol. These two usercontrols have the same datacontext. MainView: <Grid> //Column defs ... <ListView Grid.Column="0" ItemSource="{Binding Foo}"> ... <DataTemplate> <Views: FooView1 /> </DataTemplate> </ListView> <TextBlock Text="{Binding Foo.Count}" /> <StackPanel Grid.Column="1"> <Views: FooView2 /> </StackPanel> <Grid> FooView1: <UserControl> <TextBlock Text="{Binding Foo.Title}"> </UserControl> FooView2: <UserControl> <TextBlock Text="{Binding Foo.Detail1}"> <TextBlock Text="{Binding Foo.Detail2}"> <TextBlock Text="{Binding Foo.Detail3}"> <TextBlock Text="{Binding Foo.Detail4}"> </UserControl> I've no IDE here. Excuse me if there is any syntax error When the user clicks on a button. These two usercontrols have to be replaced by another two usercontrols, so the datacontext changes, the main ui remaining the same. ie, FooView1 by BarView1 and FooView2 by BarView2 In short i want to bind this view changes in mainview to my command (command from Button) How can i do this? Also tell me if i could merge the usercontrol pairs, so that only one view exists for each viewmodel ie, FooView1 and FooView2 into FooView and so on...

  • detecting object-reference duplication across JavaScript files

    - by AnC
    I have a number of files with contents like this: function hello() { ... element1.text = foo.locale.lorem; element2.text = foo.locale.ipsum; ... elementn.text = foo.locale.whatever; ... } function world() { ... var label = bar.options.baz.blah; var toggle = bar.options.baz.use_toggle; ... } This could be written more efficiently, and also be more readable, by creating a shortcut to the locale object: function hello() { var loc = foo.locale; ... element1.text = loc.lorem; element2.text = loc.ipsum; ... elementn.text = loc.whatever; ... } function world() { var options = bar.options.baz; ... var label = options.blah; var toggle = options.use_toggle; ... } Is there a simple way to detect occurrences of such duplication for any arbitrary object (it's not always as simple as "locale", or foo.something)? Basically, I wanna know where lengthy object references appear two or more times within a function. Thanks!

  • Optimization of Function with Dictionary and Zip()

    - by eWizardII
    Hello, I have the following function: def filetxt(): word_freq = {} lvl1 = [] lvl2 = [] total_t = 0 users = 0 text = [] for l in range(0,500): # Open File if os.path.exists("C:/Twitter/json/user_" + str(l) + ".json") == True: with open("C:/Twitter/json/user_" + str(l) + ".json", "r") as f: text_f = json.load(f) users = users + 1 for i in range(len(text_f)): text.append(text_f[str(i)]['text']) total_t = total_t + 1 else: pass # Filter occ = 0 import string for i in range(len(text)): s = text[i] # Sample string a = re.findall(r'(RT)',s) b = re.findall(r'(@)',s) occ = len(a) + len(b) + occ s = s.encode('utf-8') out = s.translate(string.maketrans("",""), string.punctuation) # Create Wordlist/Dictionary word_list = text[i].lower().split(None) for word in word_list: word_freq[word] = word_freq.get(word, 0) + 1 keys = word_freq.keys() numbo = range(1,len(keys)+1) WList = ', '.join(keys) NList = str(numbo).strip('[]') WList = WList.split(", ") NList = NList.split(", ") W2N = dict(zip(WList, NList)) for k in range (0,len(word_list)): word_list[k] = W2N[word_list[k]] for i in range (0,len(word_list)-1): lvl1.append(word_list[i]) lvl2.append(word_list[i+1]) I have used the profiler to find that it seems the greatest CPU time is spent on the zip() function and the join and split parts of the code, I'm looking to see if there is any way I have overlooked that I could potentially clean up the code to make it more optimized, since the greatest lag seems to be in how I am working with the dictionaries and the zip() function. Any help would be appreciated thanks!

  • First and last UITableViewCell keep changing while scrolling.

    - by W Dyson
    I have a tableView with cells containing one UITextField as a subview for each cell. My problem is that when I scroll down, the text in the first cell is duplicated in the last cell. I can't for the life if me figure out why. I have tried loading the cells from different nibs, having the textFields as ivars. The UITextFields don't seem to be the problem, I'm thinking it has something to do with the tableView reusing the cells. The textFields all have a data source that keeps track of the text within the textField and the text is reset each time the cell is shown. Any ideas? UPDATE: Thanks guys, here's a sample: - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { NSLog(@"Section %i, Row %i", indexPath.section, indexPath.row); static NSString *JournalCellIdentifier = @"JournalCellIdentifier"; UITableViewCell *cell = (UITableViewCell *)[self.tableView dequeueReusableCellWithIdentifier:JournalCellIdentifier]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:JournalCellIdentifier] autorelease]; cell.selectionStyle = UITableViewCellSelectionStyleNone; cell.accessoryType = UITableViewCellAccessoryNone; } if (indexPath.section == 0) { UITextField *textField = (UITextField *)[self.authorCell viewWithTag:1]; [cell addSubview:textField]; self.authorTextField = textField; self.authorTextField.text = [self.textFieldDictionary objectForKey:@"author"]; NSLog(@"Reading Author:%@", [self.textFieldDictionary objectForKey:@"author"]); } else if (indexPath.section == 1) { UITextField *textField = (UITextField *)[self.yearCell viewWithTag:1]; [cell addSubview:textField]; self.yearTextField = textField; self.yearTextField.text = [self.textFieldDictionary objectForKey:@"year"]; NSLog(@"Reading Year:%@", [self.textFieldDictionary objectForKey:@"year"]); } else if (indexPath.section == 2) { UITextField *textField = (UITextField *)[self.volumeCell viewWithTag:1]; [cell addSubview:textField]; self.volumeTextField = textField; self.volumeTextField.text = [self.textFieldDictionary objectForKey:@"volume"]; NSLog(@"Reading Volume:%@", [self.textFieldDictionary objectForKey:@"volume"]); } return cell; }

  • Javascript private member on prototype...

    - by Wilq32
    Well I tried to figure out is this possible in any way. Here is code: a=function(text) { var b=text; if (!arguments.callee.prototype.get) arguments.callee.prototype.get=function() { return b; } else alert('already created!'); } var c=new a("test"); // creates prototype instance of getter var d=new a("ojoj"); // alerts already created alert(c.get()) // alerts test alert(d.get()) // alerts test from context of creating prototype function :( As you see I tried to create prototype getter. For what? Well if you write something like this: a=function(text) { var b=text; this.getText=function(){ return b} } ... everything should be fine.. but in fact every time I create object - i create getText function that uses memory. I would like to have one prototypical function lying in memory that would do the same... Any ideas? EDIT: I tried solution given by Christoph, and it seems that its only known solution for now. It need to remember id information to retrieve value from context, but whole idea is nice for me :) Id is only one thing to remember, everything else can be stored once in memory. In fact you could store a lot of private members this way, and use anytime only one id. Actually this is satisfying me :) (unless someone got better idea). someFunc = function() { var store = new Array(); var guid=0; var someFunc = function(text) { this.__guid=guid; store[guid++]=text; } someFunc.prototype.getValue=function() { return store[this.__guid]; } return someFunc; }() a=new someFunc("test"); b=new someFunc("test2"); alert(a.getValue()); alert(b.getValue());

  • JSF myfaces dataTable , how to avoid NBSP; tags in the TDs

    - by Peter
    Hi, I have style applied to the TD elements of the dataTable of my myfaces application. td.financialReportTd { font-family: Arial; font-size: 12px; line-height: 12px; color:black; background-color: white; padding-right: 5px; text-align: right; border:0px black solid; height: 30px; padding-top:4px; padding-left:4px; vertical-align: top; direction: rtl; } Output: <td class="financialReportTd"> &nbsp;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp;&nbsp;MY TEXT </td> No matter what I try, those NBSP tags fill up the TD and position of the text changes to the worse. I tried style text-align:right; (I need RTL text), I tried direction: rtl; Nothing helps. How can I align my text to the very right of the TD and avoid those space tags?

  • Where do you put your dependencies?

    - by The All Foo
    If I use the dependency injection pattern to remove dependencies they end up some where else. For example, Snippet 1, or what I call Object Maker. I mean you have to instantiate your objects somewhere...so when you move dependency out of one object, you end up putting it another one. I see that this consolidates all my dependencies into one object. Is that the point, to reduce your dependencies so that they all reside in a single ( as close to as possible ) location? Snippet 1 - Object Maker <?php class ObjectMaker { public function makeSignUp() { $DatabaseObject = new Database(); $TextObject = new Text(); $MessageObject = new Message(); $SignUpObject = new ControlSignUp(); $SignUpObject->setObjects($DatabaseObject, $TextObject, $MessageObject); return $SignUpObject; } public function makeSignIn() { $DatabaseObject = new Database(); $TextObject = new Text(); $MessageObject = new Message(); $SignInObject = new ControlSignIn(); $SignInObject->setObjects($DatabaseObject, $TextObject, $MessageObject); return $SignInObject; } public function makeTweet( $DatabaseObject = NULL, $TextObject = NULL, $MessageObject = NULL ) { if( $DatabaseObject == 'small' ) { $DatabaseObject = new Database(); } else if( $DatabaseObject == NULL ) { $DatabaseObject = new Database(); $TextObject = new Text(); $MessageObject = new Message(); } $TweetObject = new ControlTweet(); $TweetObject->setObjects($DatabaseObject, $TextObject, $MessageObject); return $TweetObject; } public function makeBookmark( $DatabaseObject = NULL, $TextObject = NULL, $MessageObject = NULL ) { if( $DatabaseObject == 'small' ) { $DatabaseObject = new Database(); } else if( $DatabaseObject == NULL ) { $DatabaseObject = new Database(); $TextObject = new Text(); $MessageObject = new Message(); } $BookmarkObject = new ControlBookmark(); $BookmarkObject->setObjects($DatabaseObject,$TextObject,$MessageObject); return $BookmarkObject; } }

At this point i have 3 options : Build from scratch on top of clr :( Find functionnalities among several open source framework and use them as a stack for infrastucture Find a "software factory" I know its lot but i really would like to use existing code to build upon so i can focus on business rules.

  • Drools - Doing Complex Stuff inside a Rule Condition or Consequence

    - by mfcabrera
    Hello, In my company we are planning to use Drools a BRE for couple of projects. Now we trying to define some best-practices. My question is what should be and shouldn't be done inside a Rule Condition/Consequence. Given that we can write Java directly or call methods (for example From a Global object in the Working Memory). Example. Given a Rule that evaluates a generic Object (e.g. Person) have property set to true. Now, that specific propertie can only be defined for that Object going to the database and fetching that info. So we have two ways of implementing that: Alternative A: Go to the database and fetch the object property (true/false, a code) Insert the Object in the working memory Evaluate the rule Alternative B: Insert a Global Object that has a method that connects to the database and check for the property for the given object. Insert the Object to eval in Working Memory In the rule, call the Global Object and perform the access to the database Which of those is considered better? I really like A, but sometimes B is more straightforward, however what would happen if something like a Exception from the Database is raised? I have seen the alternative B implemented in the Drools 5.0 Book from Packt Publishing,however they are doing a mocking and they don't talk about the actual implications of going to the database at all. Thank you,

  • PDO closeCursor Error

    - by Metropolis
    Hey Everyone, I currently have a database layer that I wrote myself and I have been using it now for over a year without any problems. The database class uses PDO, and there are two different databases that I regularly connect to (MySQL and MS SQL). The MS SQL database is used for Accpac accounting storage, and the MySQL database is used for everything else. In one of the MySQL databases I have all of the dsn's listed which I use to create the string I need to connect to the MS SQL databases. I have a new program I am trying to write which I am taking employee data from one of the MySQL databases, and using the employee ID to get the employee's information from the MS SQL database. For some reason, whenever I run the program it will get through about 1200 records (out of 11k) and then crash with an error like the following, Fatal error: Call to a member function closeCursor() on a non-object I have tried moving the loops around in many different ways, and I have tried manually closing the connections by setting the database handle to null. Nothing I do seems to work. Thanks for any help! Metropolis

  • Quick and easy flood protection?

    - by James P
    I have a site where a user submits a message using AJAX to a file called like.php. In this file the users message is submitted to a database and it then sends a link back to the user. In my Javascript code I disabled the text box the user types into when they submit the AJAX request. The only problem is, a malicious user can just constantly send POST requests to like.php and flood my database. So I would like to implement simple flood protection. I don't really want the hassle of another database table logging users IPs and such... as if they are flooding my site there will be a lot of database read/writes slowing it down. I thought about using sessions, like have a session that contains a timestamp that gets checked every time they send data to like.php, and if the current time is before the timestamp let them add data to the database, otherwise send out an error and block them. If they are allowed to enter something into the database, update their session with a new timestamp. What do you think? Would this be the best way to go about it or are there easier alternatives? Thanks for any help. :)

    - by Jeff V
    I'm still pretty new at Silverlight so there might be a way to do this, but I'm just unfamiliar with the terminology... I basically have this grouping of textboxes and textblocks and I would like to repeat this same grouping whenever the addNew button is clicked. Is there a way to do this by creating some sort of template? Or do I have to add each item individually. <Grid> <toolkit:ListPicker Height="70" HorizontalAlignment="Right" Name="listPicker1" VerticalAlignment="Top" Width="56" ItemTemplate="{StaticResource PickerItemTemplate}" FullModeItemTemplate="{StaticResource PickerFullModeItemTemplate}" Margin="0,97,167,0"></toolkit:ListPicker> <TextBlock Height="33" HorizontalAlignment="Left" Margin="10,7,0,0" Name="tbDate" Text="Date:" VerticalAlignment="Top" Width="266" /> <TextBlock Height="42" HorizontalAlignment="Left" Margin="9,55,0,0" Name="tbItem" Text="Item:" VerticalAlignment="Top" Width="90" /> <TextBox Height="75" HorizontalAlignment="Left" Margin="92,33,0,0" Name="tbItemName" Text="" VerticalAlignment="Top" Width="341" /> <TextBlock Height="42" HorizontalAlignment="Left" Margin="5,118,0,0" Name="tbServing" Text="Serving:" VerticalAlignment="Top" Width="99" /> <TextBox Height="70" HorizontalAlignment="Left" Margin="90,96,0,0" Name="tbServingValue" Text="" VerticalAlignment="Top" Width="75" /> <TextBlock Height="42" HorizontalAlignment="Left" Margin="156,120,0,0" Name="tbUOM" Text="UOM:" VerticalAlignment="Top" Width="60" /> <Button Content="" HorizontalAlignment="Right" Height="63" Margin="0,100,13,0" VerticalAlignment="Top" Width="132" RenderTransformOrigin="0.455,0.286" Style="{StaticResource wp7_buttonAddNew}" x:Name="btnAddNewItem" Click="btnAddNewItem_Click"/> </Grid> Thanks!

  • Who needs singletons?

    - by sexyprout
    Imagine you access your MySQL database via PDO. You got some functions, and in these functions, you need to access the database. The first thing I thought of is global, like: $db = new PDO('mysql:host=127.0.0.1;dbname=toto', 'root', 'pwd'); function some_function() { global $db; $db->query('...'); } But it's considered as a bad practice. So, after a little search, I ended up with the Singleton pattern, which "applies to situations in which there needs to be a single instance of a class." According to the example of the manual, we should do this: class Database { private static $instance, $db; private function __construct(){} static function singleton() { if(!isset(self::$instance)) self::$instance = new __CLASS__; return self:$instance; } function get() { if(!isset(self::$db)) self::$db = new PDO('mysql:host=127.0.0.1;dbname=toto', 'user', 'pwd') return self::$db; } } function some_function() { $db = Database::singleton(); $db->get()->query('...'); } some_function(); But I just can't understand why you need that big class when you can do it merely with: class Database { private static $db; private function __construct(){} static function get() { if(!isset(self::$rand)) self::$db = new PDO('mysql:host=127.0.0.1;dbname=toto', 'user', 'pwd'); return self::$db; } } function some_function() { Database::get()->query('...'); } some_function(); This last one works perfectly and I don't need to worry about $db anymore. But maybe I'm forgetting something. So, who's wrong, who's right?

  • GADTs and Scrap your Boilerplate

    - by finnsson
    I'm writing a XML (de)serializer using Text.XML.Light and Scrap your Boilerplate (at http://github.com/finnsson/Text.XML.Generic) and so far I got working code for "normal" ADTs but I'm stuck at deserializing GADTs. I got the GADT data DataBox where DataBox :: (Show d, Eq d, Data d) => d -> DataBox and I'm trying to get this to compile instance Data DataBox where gfoldl k z (DataBox d) = z DataBox `k` d gunfold k z c = k (z DataBox) -- not OK toConstr (DataBox d) = toConstr d dataTypeOf (DataBox d) = dataTypeOf d but I can't figure out how to implement gunfold for DataBox. The error message is Text/XML/Generic.hs:274:23: Ambiguous type variable `b' in the constraints: `Eq b' arising from a use of `DataBox' at Text/XML/Generic.hs:274:23-29 `Show b' arising from a use of `DataBox' at Text/XML/Generic.hs:274:23-29 `Data b' arising from a use of `k' at Text/XML/Generic.hs:274:18-30 Probable fix: add a type signature that fixes these type variable(s) It's complaining about not being able to figure out the data type of b. I'm also trying to implement dataCast1 and dataCast2 but I think I can live without them (i.e. an incorrect implementation). I guess my questions are: Is it possible to combine GADTs with Scrap your Boilerplate? If so: how do you implement gunfold for a GADT?
