  • Reporting services and custom library

    - by niao
    Greetings, In my Reporting Services report I've added reference to my custom library. It works fine. I can display the string which is returned from my custom library method as follows: =ClassLibrary1.MyClass.Parse("harry potter") Above code works fine - it should return SQL query based on passed parameters. My question is, how can I use this code in my DataSource. I'm trying to do something like this: SELECT * FROM =ClassLibrary1.MyClass.Parse(@searchedPhrase) But the above code does not work and the error is returned :"Incorrect syntax near ="

  • lua userdata gc

    - by anon
    Is it possible for a piece of lua user data to hold reference to a lua object? (Like a table, or another piece of user data?). Basically, what I want to know is: Can I create a piece of userdata in such a way taht when the gc runs, the user data can say: "Hey! I'm holding references to these other objects, mark them as well." Thanks!

  • Linux: shell builtin string matching

    - by gmatt
    I am trying to become more familiar with using the builtin string matching stuff available in shells in linux. I came across this guys posting, and he showed an example a="abc|def" echo ${a#*|} # will yield "def" echo ${a%|*} # will yield "abc" I tried it out and it does what its advertised to do, but I don't understand what the $,{},#,*,| are doing, I tried looking for some reference online or in the manuals but I couldn't find anything. Can anyone explain to me what's going on here?

  • Must I Install a Gem to Unpack It?

    - by yar
    I wrote up some instructions for freezing a non-native gem in a Rails app today: install the gem sudo gem install fastercsv put the reference in the environment.rb (I think this is only necessary to do unpack with no GEM specified) config.gem "fastercsv" unpack the gem rake gems:unpack GEM=fastercsv uninstall the gem sudo gem uninstall fastercsv I know this must be the long way around: how can I unpack the gem without installing it first? Also: What's the difference between rake gems:unpack GEM=fastercsv and gem unpack fastercsv?

  • Processing image data in java me

    - by Trimack
    Hi, I want to process raw data from a picture taken in java me with byte[] snap = videoControl.getSnapshot(encoding); My question is, whether I should try working already with snap or should I first create the image from this array Image im = Image.createImage(snap, 0, snap.length); and then work with that? Or is there some better documentation of both methods, i.e. getSnapshot and createImage than the Java API reference?

  • DRY Ruby Initialization with Hash Argument

    - by ktex
    I find myself using hash arguments to constructors quite a bit, especially when writing DSLs for configuration or other bits of API that the end user will be exposed to. What I end up doing is something like the following: class Example PROPERTIES = [:name, :age] PROPERTIES.each { |p| attr_reader p } def initialize(args) PROPERTIES.each do |p| self.instance_variable_set "@#{p}", args[p] if not args[p].nil? end end end Is there no more idiomatic way to achieve this? The throw-away constant and the symbol to string conversion seem particularly egregious.

  • Extracting fields from a define-type object in Scheme

    - by Mike
    Hi, I am trying to extract the field 'name' or 'named-expr' from the following object: (bind 'x (num 5)) ;; note that this is not a list, but a type Binding With the Binding definition: (define-type Binding (bind (name symbol?) (named-expr WAE?))) I have tried, but received the error "reference to an identifier before its definition: Binding-name." Here is what I tried typing: (begin (Binding-name (bind 'x (num 5)))) (begin (define x (bind 'x (num 5))) (Binding-name x)) Thank you!

  • Iterating Collection In Two Threads

    - by ChloeRadshaw
    This question relates both to C# and Java If you have a collection which is not modified and that collection reference is shared between two threads what happens when you iterate on each thread?? ThreadA: Collection.iterator ThreadA: Collection.moveNext ThreadB: Collection.iterator ThreadB: Collection.moveNext Will threadB see the first element? Is the iterator always reset when it is requested? What happens if this is interleaved so movenext and item is interleaved? Is there a danger that you dont process all elements??

  • Speeding up templates in GAE-Py by aggregating RPC calls

    - by Sudhir Jonathan
    Here's my problem: class City(Model): name = StringProperty() class Author(Model): name = StringProperty() city = ReferenceProperty(City) class Post(Model): author = ReferenceProperty(Author) content = StringProperty() The code isn't important... its this django template: {% for post in posts %} <div>{{post.content}}</div> <div>by {{post.author.name}} from {{post.author.city.name}}</div> {% endfor %} Now lets say I get the first 100 posts using Post.all().fetch(limit=100), and pass this list to the template - what happens? It makes 200 more datastore gets - 100 to get each author, 100 to get each author's city. This is perfectly understandable, actually, since the post only has a reference to the author, and the author only has a reference to the city. The __get__ accessor on the post.author and author.city objects transparently do a get and pull the data back (See this question). Some ways around this are Use Post.author.get_value_for_datastore(post) to collect the author keys (see the link above), and then do a batch get to get them all - the trouble here is that we need to re-construct a template data object... something which needs extra code and maintenance for each model and handler. Write an accessor, say cached_author, that checks memcache for the author first and returns that - the problem here is that post.cached_author is going to be called 100 times, which could probably mean 100 memcache calls. Hold a static key to object map (and refresh it maybe once in five minutes) if the data doesn't have to be very up to date. The cached_author accessor can then just refer to this map. All these ideas need extra code and maintenance, and they're not very transparent. What if we could do @prefetch def render_template(path, data) template.render(path, data) Turns out we can... hooks and Guido's instrumentation module both prove it. If the @prefetch method wraps a template render by capturing which keys are requested we can (atleast to one level of depth) capture which keys are being requested, return mock objects, and do a batch get on them. This could be repeated for all depth levels, till no new keys are being requested. The final render could intercept the gets and return the objects from a map. This would change a total of 200 gets into 3, transparently and without any extra code. Not to mention greatly cut down the need for memcache and help in situations where memcache can't be used. Trouble is I don't know how to do it (yet). Before I start trying, has anyone else done this? Or does anyone want to help? Or do you see a massive flaw in the plan?

  • Ruby - How to remove a setter on an object

    - by Markus Orrelly
    Given a class like this: class B class << self attr_accessor :var end end Suppose I can't modify the original source code of class B. How might I go about removing the setter on the class variable var? I've tried using something like B.send("unset_method", "var="), but that doesn't work (nor does remove_method, or overwriting that method with a var= method that doesn't do anything). Any ideas?

  • NSMutableURLRequest and a Password with special Characters won't work

    - by twickl
    I'm writing a small program (using Cocoa Touch), which communicates with a webservice. The code for calling the webservice, is the following: - (IBAction)send:(id)sender { if ([number.text length] > 0) { [[UIApplication sharedApplication] beginIgnoringInteractionEvents]; [activityIndicator startAnimating]; NSString *modded; modded = [self computeNumber]; NSMutableURLRequest *theRequest = [NSMutableURLRequest requestWithURL: [NSURL URLWithString:@"https://tester:%=&[email protected]/RPC2"]]; [theRequest setHTTPMethod:@"POST"]; [theRequest addValue:@"text/xml" forHTTPHeaderField:@"content-type"]; [theRequest setCachePolicy:NSURLCacheStorageNotAllowed]; [theRequest setTimeoutInterval:5.0]; NSString* pStr = [[NSString alloc] initWithFormat:@"<?xml version=\"1.0\" encoding=\"UTF-8\"?><methodCall><methodName>samurai.SessionInitiate</methodName><params><param><value><struct><member><name>LocalUri</name><value><string></string></value></member><member><name>RemoteUri</name><value><string>sip:%@@sipgate.net</string></value></member><member><name>TOS</name><value><string>text</string></value></member><member><name>Content</name><value><string>%@</string></value></member><member><name>Schedule</name><value><string></string></value></member></struct></value></param></params></methodCall>", modded, TextView.text]; NSData* pBody = [pStr dataUsingEncoding:NSUTF8StringEncoding]; [theRequest setHTTPBody:pBody]; NSURLConnection *theConnection = [[NSURLConnection alloc] initWithRequest:theRequest delegate:self]; if (!theConnection) { UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Error" message:@"A Connection could not be established!" delegate:nil cancelButtonTitle:@"OK" otherButtonTitles: nil]; [alert show]; [alert release]; sendButton.enabled = TRUE; return; } [pStr release]; [pBody release]; } } The Username and Password have to be in the URL, and it works in most cases, but when the password consists of special characters like in the example "%=&=-Test2009", the Webservice does not respond. If it is something like "Test2009" it works fine. Does anyone have an idea why, and maybe a solution for that?

  • Strange problems with PHP SOAP (private variable not persist + variables passed from client not work

    - by Tamas Gal
    I have a very strange problems in a PHP Soap implementation. I have a private variable in the Server class which contains the DB name for further reference. The private variable name is "fromdb". I have a public function on the soap server where I can set this variable. $client-setFromdb. When I call it form my client works perfectly and the fromdb private variable can be set. But a second soap client call this private variable loses its value... Here is my soap server setup: ini_set('soap.wsdl_cache_enabled', 0); ini_set('session.auto_start', 0); ini_set('always_populate_raw_post_data', 1); global $config_dir; session_start(); /*if(!$HTTP_RAW_POST_DATA){ $HTTP_RAW_POST_DATA = file_get_contents('php://input'); }*/ $server = new SoapServer("{$config_dir['template']}import.wsdl"); $server-setClass('import'); $server-setPersistence(SOAP_PERSISTENCE_SESSION); $server-handle(); Problem is that I passed this to the server: $client = new SoapClient('http://import.ingatlan.net/wsdl', array('trace' = 1)); $xml=''; $xml.=''; $xml.=''; $xml.=''; $xml.='Valaki'; $xml.=''; $xml.=''; $xml.=''; $xml.=''; $tarray = array("type" = 1, "xml" = $xml); try{ $s = $client-sendXml( $tarray ); print "$s"; } catch( SOAPFault $exception){ print "--- SOAP exception :{$exception}---"; print "LAST REQUEST :"; var_dump($client-_getLastRequest()); print "---"; print "LAST RESPONSE :".$client-_getLastResponse(); } So passed an Array of informations to the server. Then I got this exception: LAST REQUEST : <?xml version="1.0" encoding="UTF-8"?> <SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"><SOAP-ENV:Body><type>Array</type><xml/></SOAP-ENV:Body></SOAP-ENV:Envelope> Can you see the Array word between the type tag? Seems that the client only passed a reference or something like this. So I totaly missed :(

  • Can I use relative XPath expressions in libxml2?

    - by brbr
    I am wondering whether it is possible to use relative XPath expressions in libxml2. This is from the javax.xml.xpath API and I would like to do the similar thing using libxml2: Node widgetNode = (Node) xpath.evaluate(expression, document, XPathConstants.NODE); With a reference to the element, a relative XPath expression can now written to select the child element: XPath xpath = XPathFactory.newInstance().newXPath(); String expression = "manufacturer"; Node manufacturerNode = (Node) xpath.evaluate(expression, **widgetNode**, XPathConstants.NODE);

  • objc[989] objc_exception_throw failed.

    - by thyrgle
    I was just adding some more CCSprites to a CCLayer and it just starts crashing giving me the error: objc[989] objc_exception_throw failed. Is there like a limit to the amount of CCSprites you can have on a screen or something? I added the CCSprites doing the following with the CCSprites already declared at interface: L1Circle1 = [CCSprite spriteWithFile:@"LaserCircle.png"]; [L1Circle1 setPosition:ccp(180,180)]; [self addChild:L1Circle1]; What am I doing wrong?

  • Elmah and 404s under IIS6

    - by tomfanning
    Just wondering if it's possible to get Elmah to log 404s that aren't picked up by the ASP.NET framework - i.e. the 404s that IIS spots and replies to. Presumably this would involve some kind of entry in IIS - web site properties - Custom Errors tab. Can't find any reference on how to do this.
