• Garbage collection of Strings returned from C# method calls in ascx pages

  - by Icarus

  Hi, For a web application developed on ASP.NET, we are finding that for user control files (ascx) we are returning long strings as a result of method calls. These are embedded in the ascx pages using the special tags <% %> When performing memory dump analysis for the application, we find that many of those strings are not being garbage collected. Also, the ascx pages are compiled to temporary DLLs and they are held in memory. Is this responsible for causing the long strings to remain in memory and not be garbage collected ? Note : The strings are larger than 85K in size.

• SQL Like question

  - by mike

  Is there a way to reverse the SQL Like operator so it searches a field backwards? For example, I have a value in a field that looks like this "Xbox 360 Video Game". If I write a query like below, it returns the result fine. SELECT id FROM table WHERE title like "%Xbox%Game%" However, when I search like this, it doesn't find any results. SELECT id FROM table WHERE title like "%Video%Xbox%" I need it to match in any direction. How can I get around this?

• How can I re-size and re-position a shadowbox/greybox window to display in a certain div element?

  - by kielie

  Hi guys, I would like to know if it is possible to re-size and re-position a greybox or shadowbox window to display in a certain div element? I am creating a template for a wordpress site, and I am using the default calendar, but when you click on a date inside of the calendar, the default action is to open it up in a new window. Would it be possible to mod greybox or shadowbox in such a way that when you click on a date, the box opens up over the calendar displaying the contents in it, instead of a new page? Or is there another way of achieving the desired result, maybe with jQuery or Javascript? Any help would be greatly appreciated, thanx in advance!

• -sizeWithFont Functions Differently on Device

  - by LucasTizma

  So I am seemingly encountering some strange behavior when using NSString's -sizeWithFont family of method calls depending on whether or not I'm invoking it on the iPhone Simulator or an actual device. Simply enough, when the receiver of the -sizeWithFont method call is nil, the resulting CGSize passed back on the Simulator is {0, 0}. However, on the device, it is the size of the bounding rectangle I specified in the method call. See the following log statements: Simulator: someString: (null) someStringSize: {0, 0} Device: someString: (null) someStringSize: {185, 3.40282e+38} The behavior on the Simulator is what I would expect. Not that this issue is difficult to circumvent, but 1) I'm a little confused why this family of functions would behave differently on the Simulator and an actual device, and 2) why does calling a method on a nil receiving return a particular result? Thanks for any pointers or insight you guys can provide! EDIT: I suppose I should mention that I'm building against the 3.1 SDK.

• List the names of existing directories from .tgz file in a bash variable

  - by Tom

  I would like to find all the directories that are in a .tgz file and that already exist on the system and put the result in a bash variable. I have tried this: EXISTING=`for f in \`tar tzf $ARCHIVE\`; do if [ -d "/tmp/unpacked-data/\$f" ]; then echo \$f; fi; done` with no luck. If I echo the value of $f before the if in the loop, I get all the files, ie this works: EXISTING=`for f in \`tar tzf $ARCHIVE\`; do echo \$f; done` Can someone tell me why the \$f doesn't work in the if statement? Thanks, Tom

• Write wave files to memory in Java

  - by Cliff

  I'm trying to figure out why my servlet code creates wave files with improper headers. I use: AudioSystem.write( new AudioInputStream( new ByteArrayInputStream(memoryBytes), new AudioFormat(22000, 16, 1, true,false), memoryBytes.length ), AudioFileFormat.Type.WAVE, servletOutputStream ); taking a byte array from memory containing raw PCM samples and a servlet output stream that gets returned to the client. In the result I get a normal wave file but with zeros in the chunk size fields. Is the API broken? I would think that the size could be filled in using the size passed in the audio input stream. But now, after typing this out I'm thinking its not making this info available to the outer write() method on AudioSystem. It seems like the AudioSystem.write call needs a size parameter unless it is able to pull the size from the stream... which wouldn't work with an arbitrary sized stream. Does anyone know how to make this example work?

• If I specify a System property multiple times when invoking JVM which value is used?

  - by RobV

  If I specify a system property multiple times when invoking the JVM which value will I actually get when I retrieve the property? e.g. java -Dprop=A -Dprop=B -jar my.jar What will be the result when I call System.getProperty("prop");? The Java documentation on this does not really tell me anything useful on this front. In my non-scientific testing on a couple of machines running different JVMs it seems like the last value is the one returned (which is actually the behavior I need) but I wondered if this behavior is actually defined officially anywhere or can it vary between JVMs?

• UDDI - find service which name matches exactly name specified in request

  - by empi

  Hi. I'm asking UDDI to find a service with a name specified in request. The code looks like this: UddiConnection uddiConnection = new UddiConnection(uddiAddress); FindService findService = new FindService(); findService.Names.Add(uddiServiceName); ServiceList foundServices = findService.Send(uddiConnection); However, when I ask for SomeService and UDDI has two services SomeService and SomeServiceSecond I get both in found services. How can I ask for service that name exactly matches the name specified? I know I can check the result in my class and limit found services collection but I would like to specify my needs in UDDI inquire. Thanks in advance for help.

• Reverse rendering of Urdu fonts

  - by Syed Muhammad Umair

  I am working on a project that is based on Urdu language in Ubuntu platform. I'm using Python language and have almost achieved my task. The problem is that, the Urdu text is rendered in reverse order. For example, consider the word ??? (which means work) consisting of the three letters: ? , ? , and ? The output is rendered in reverse order as ??? consisting of the three letters: ?, ?, and ? When copying this text to Open Office or opening the generated XML file in Firefox, the generated result is absolutely desired. I Am using Python 2.6 IDLE, its working perfect with Windows platform, which clearly shows its not the problem of IDLE. Am working on TKINTER GUI library. How can this problem be solved?

• How do I set a time in a time_select view helper?

  - by brad

  I have a time_select in which I am trying to set a time value as follows; <%= f.time_select :start_time, :value => (@invoice.start_time ? @invoice.start_time : Time.now) %> This always produces a time selector with the current time rather than the value for @invoice.start_time. @invoice.start_time is in fact a datetime object but this is passed to the time selector just fine if I use <%= f.time_select :start_time %> I guess what I'm really asking is how to use the :value option with the time_select helper. Attempts like the following don't seem to produce the desired result; <%= f.time_select :start_time, :value => (Time.now + 2.hours) %> <%= f.time_select :start_time, :value => "14:30" %>

• Trying to recognize _NSFaultingMutableSet as member of NSSet

  - by Will

  I'm trying to recognize the result of a generic query to a managed object as an NSSet. Currently the class returned is a member of _NSFaultingMutableSet, which is clearly related, but fails the isMemberOf:[NSSet class] and isKindOf:[NSSet class] calls. Given that Cocoa doesn't do a direct implementation of NSSet, it's not surprising that I've got some air in the pipes, but I'm wondering if I'm messing something obvious up or this requires a higher grade of kung-fu than I possess. Code follows: SEL selector = NSSelectorFromString(someString); if(![self respondsToSelector:selector]){ NSLog(@"Error processing item"); return; } id items = [self performSelector:selector]; Class itemsClass = [items class]; if ( [itemsClass isKindOfClass:[NSSet class]]) { // do something }

• How to call an extended procedure from a function

  - by Alan Featherston Lago

  hi im having trouble trying to get the following function to work. CREATE FUNCTION test ( @nt_group VARCHAR(128) ) RETURNS @nt_usr TABLE ( [name] [nchar](128) NULL , [type] [char](8) NULL , [privilege] [char](9) NULL , [mapped login name] [nchar](128) NULL , [permission path] [nchar](128) NULL ) AS BEGIN INSERT INTO @nt_usr EXEC master.dbo.xp_logininfo 'DOMAIN\USER', @nt_group RETURN END As far as i know i should be allowed to call an extended stored procedure, im getting the following error Mes 443, Level 16, State 14 Could it be that xp_logininfo might return different result sets depending on the parameters? When i use openquery i can overcome this by setting this: SET FMTONLY OFF. Does anyone know if there's a similar workaround for my problem?

• How to determine if an event is already subscribed

  - by Ram

  Hi, In my .NET application I am subscribing to events from another class. The subscription is conditional. I am subscribing to events when the control is visible and de-subscribing it when it become invisible. However in some conditions I do not want to de-subscribe the event even if the control is not visible as I want the result of an operation which is happening on background thread . Is there any way through which I can determine if a that class has already subscribed to that event. I know we can do it in the class which will raise that event by checking event with null but I don not know how to do it in a class which will subscribe to that event.

• Iterator blocks in Clojure?

  - by Checkers

  I am using clojure.contrib.sql to fetch some records from an SQLite database. (defn read-all-foo [] (with-connection *db* (with-query-results res ["select * from foo"] (into [] res)))) Now, I don't really want to realize the whole sequence before returning from the function (i.e. I want to keep it lazy), but if I return res directly or wrap it some kind of lazy wrapper (for example I want to make a certain map transformation on result sequence), SQL-related bindings will be reset and connection will be closed after I return, so realizing the sequence will throw an exception. How can I enclose the whole function in a closure and return a kind of iterator block (like yield in C# or Python)? Or is there another way to return a lazy sequence from this function?

• goo.gl Api: How to know if URL was added to user's history?

  - by Manuel

  I'm using the goo.gl API as described here. It's easy to use and it works with or without authantication (I'm using OAuth). So, if I provide the OAuth token / secret, the shortened URL is added to the users history. My problem is, that I would like to show to the user that the shortened URL was added to his goo.gl history. The respone you get from the shortening request, however, is always the same, whether you use authorization or not: { "kind": "urlshortener#url", "id": "http://goo.gl/fbsS", "longUrl": "http://www.google.com/" } So, does anyone know a way to find out, if the shortened URL was successfully added to the user's history? Is there a parameter you can add to the request URL that leads to a more detailed result string?

• How do you implement caching in Linq to SQL?

  - by Glenn Slaven

  We've just started using LINQ to SQL at work for our DAL & we haven't really come up with a standard for out caching model. Previously we had being using a base 'DAL' class that implemented a cache manager property that all our DAL classes inherited from, but now we don't have that. I'm wondering if anyone has come up with a 'standard' approach to caching LINQ to SQL results? We're working in a web environment (IIS) if that makes a difference. I know this may well end up being a subjective question, but I still think the info would be valuable. EDIT: To clarify, I'm not talking about caching an individual result, I'm after more of an architecture solution, as in how do you set up caching so that all your link methods use the same caching architecture.

• Why uses git fast-forward merging per default?

  - by Florian Pilz

  Coming from mercurial, I'm using branches to organize features. Naturally I want to see this work-flow in my history as well. But I started my new project with git and finished a feature. After merging I realized that git used fast-forward and forgot about my branch. So to think into the future: I'm the only one working on this project. If I use the default approach of git (fast-forward merging) my history would result in one giant master branch. I don't want this and can't see any good reason making this default. Maybe there are reasons, but what's so striking about it, that it has to be the default action?

• Python Closures Example Code

  - by user336527

  I am learning Python using "Dive Into Python 3" book. I like it, but I don't understand the example used to introduce Closures in Section 6.5. I mean, I see how it works, and I think it's really cool. But I don't see any real benefit: it seems to me the same result could be achieved by simply reading in the rules file line by line in a loop, and doing search / replace for each line read. Could someone help me to: either understand why using closures in this example improves the code (e.g., easier to maintain, extend, reuse, or debug?) or suggest a source of some other real-life code examples where closures really shine? Thank you!
