• Making ANTLR generated class files into one jar file.

  - by prosseek

  With ANTLR, I get some java class files after compilation. And I need to make all the class files into one jar file. I make manifest.mf file that has one line "Main-class: Test" to indicate the main file. I run 'jar cmf manifest.mf hello.jar *.class' to get hello.jar file. But when I try to run 'java -jar hello.jar', I get the following error messages. $ java -jar hello.jar Exception in thread "main" java.lang.NoClassDefFoundError: Test Caused by: java.lang.ClassNotFoundException: Test at java.net.URLClassLoader$1.run(URLClassLoader.java:200) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:188) at java.lang.ClassLoader.loadClass(ClassLoader.java:315) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:330) at java.lang.ClassLoader.loadClass(ClassLoader.java:250) at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:398) What's wrong? I get correct result when I run 'java Test'. The example that I used is the source code from the book 'The Definitive ANTLR Reference' that you can download from http://www.pragprog.com/titles/tpantlr/source_code The example is in /tour/trees/. I get a bunch of class files after compiling g and java files.

• Algorithm To Select Most Popular Places from Database

  - by Russell C.

  We have a website that contains a database of places. For each place our users are able to take one of the follow actions which we record: VIEW - View it's profile RATING - Rate it on a scale of 1-5 stars REVIEW - Review it COMPLETED - Mark that they've been there WISH LIST - Mark that they want to go there FAVORITE - Mark that it's one of their favorites In our database table of places each place contains a count of the number of times each action above was taken as well as the average rating given by users. views ratings avg_rating completed wishlist favorite What we want to be able to do is generate lists of the top places using the above information. Ideally, we would want to be able to generate this list using a relatively simple SQL query without needing to do any legwork to calculate additional fields or stack rank places against one another. That being said, since we only have about 50,000 places we could run a nightly cron job to calculate some fields such as rankings on different categories if it would make a meaningful difference in the overall results of our top places. I'd appreciate if you could make some suggestions on how we should think about bubbling the best places to the top, which criteria we should weight more heavily, and given that information - suggest what the MySQL query would need to look like in order to select the top 10 places. One thing to note is that at this time we are less concerned with the recency of a place being popular - meaning that looking at the aggregate information is fine and that more recent data doesn't need to be weighted more heavily. Thanks in advance for your help & advice!

• Boost::Mutex & Malloc

  - by M. Tibbits

  Hi all, I'm trying to use a faster memory allocator in C++. I can't use Hoard due to licensing / cost. I was using NEDMalloc in a single threaded setting and got excellent performance, but I'm wondering if I should switch to something else -- as I understand things, NEDMalloc is just a replacement for C-based malloc() & free(), not the C++-based new & delete operators (which I use extensively). The problem is that I now need to be thread-safe, so I'm trying to malloc an object which is reference counted (to prevent excess copying), but which also contains a mutex pointer. That way, if you're about to delete the last copy, you first need to lock the pointer, then free the object, and lastly unlock & free the mutex. However, using malloc to create a boost::mutex appears impossible because I can't initialize the private object as calling the constructor directly ist verboten. So I'm left with this odd situation, where I'm using new to allocate the lock and nedmalloc to allocate everything else. But when I allocate a large amount of memory, I run into allocation errors (which disappear when I switch to malloc instead of nedmalloc ~ but the performance is terrible). My guess is that this is due to fragmentation in the memory and an inability of nedmalloc and new to place nice side by side. There has to be a better solution. What would you suggest?

• Problem using structured data with sproxy-generated proxy c++ class

  - by Odrade

  I am attempting to communicate structured data types between a Visual C++ client application and an ASP.NET web service. I'm am having issues whenever any parameter or return type is not a basic type (e.g. string, int, float, etc). To illustrate the issue, I created the following ASP.NET web service: namespace TestWebService { [WebService(Namespace = "http://localhost/TestWebService")] [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)] [ToolboxItem(false)] public class Service1 : System.Web.Services.WebService { [WebMethod] public TestData StructuredOutput() { TestData td = new TestData(); td.data = 1729; return td; } } public class TestData { public int data; } } To consume the service, I created a dirt-simple Visual C++ client in VS2005. I added a web reference to the project, which caused sproxy to generate a proxy class for me. With the generated header properly included, I attempted to invoke the service like this: int _tmain(int argc, _TCHAR* argv[]) { CoInitialize(NULL); Service1::CService1 ws; Service1::TestData td; HRESULT hr = ws.StructuredOutput(&td); //data is returned as expected CoUninitialize(); return 0; } // crashes here with access violation The call to StructuredOutput returns the data as expected, but an access violation occurs on destruction of the CService1 object. The access violation is occurring here (from atlsoap.h): void UninitializeSOAP() { if (m_spReader.p != NULL) { m_spReader->putContentHandler(NULL); //access violation m_spReader.Release(); } } I see the same behavior when using a TestData object as an input parameter, or when using any other structured data types as input or output. When I use basic types for input/output from the web service I do not experience these errors. Any ideas about why this might be happening? Is sproxy screwing something up, or am I? NOTE: I'm aware of gSOAP and the wsdl2h tool, but those aren't freely available for commercial use (and nobody here is going to buy a license). I am open to alternatives for generating the c++ proxy, as long as they are free for commercial use.

• What is the best way to get an audio file duration in Android?

  - by Gilead

  Hi! I'm using a SoundPool [ 1 ] to play audio clips in my app. All is fine but I need to know when the clip playback has finished. At the moment I track it in my app by obtaining the duration of each clip using a MediaPlayer [ 2 ] instance. That works fine but it looks wasteful to load each file twice, just to get the duration. I could roughly calculate the duration myself knowing the length of the file (available from the AssetFileDescriptor [ 3 ]) but I'd still need to know the sample rate and the number of channels. I see two potential solutions to that problem: Figuring out when a clip has finished playing (doesn't seem to be possible with SoundClip). Having a class which could load just the header of an audio file and give me the sample rate/number of channels (and, ideally, the sample count to get the exact duration). Any suggestions? Thanks, Max The code I'm using at the moment (works fine but is rather heavy for the purpose): String[] fileNames = ... MediaPlayer mp = new MediaPlayer(); for (String fileName : fileNames) { AssetFileDescriptor d = context.getAssets().openFd(fileName); mp.reset(); mp.setDataSource(d.getFileDescriptor(), d.getStartOffset(), d.getLength()); mp.prepare(); int duration = mp.getDuration(); // ... } On a side note, this question has already been asked [ 4 ] but got no answers.

• Placement/Positioning/Alignment of UIScrollView w.r.t. length of Title NSString

  - by Shoaibi

  I have a scenario where i show stuff like: ----------------------------------- titleview (UITextView) ______________ tArea (UIScrollView) ttextview (UITextView) ----------------------------------- Now here is the condition: Length of titleview's text is dynamic, varies based on user input. Because of the condition I have trouble placing tArea e.g. UIScrollView on the screen, it either appears way too below than the titleview, or overlaps it. Previously what i did: Count the number of characters in titleview.text.length and divide them by 27 (e.g. characters in one line when using boldSystemFontOfSize:20) and multiply by 10 to get the starting X of tArea e.g. UIScrollView. But that sucked. Because i had to duplicate code for rotation to landscape. What do i have now? : CGSize titlesize = [title sizeWithFont:[UIFont systemFontOfSize:20] constrainedToSize:CGSizeMake(5, 90) lineBreakMode:UILineBreakModeWordWrap]; ttitleview = [[UITextView alloc] initWithFrame:CGRectMake(5, 5, 310,titlesize.height)]; ttitleview.text = title; ttitleview.font = [UIFont boldSystemFontOfSize:20]; ttitleview.backgroundColor = [UIColor clearColor]; ttitleview.editable = NO; [self.view addSubview:ttitleview]; CGSize textsize = [ttext sizeWithFont:[UIFont systemFontOfSize:20] constrainedToSize:CGSizeMake(5, 350) lineBreakMode:UILineBreakModeWordWrap]; tArea = [[UIScrollView alloc] initWithFrame:CGRectMake(5, titlesize.height, 310, 230)]; tArea.contentSize = CGSizeMake(310, textsize.height+20); tArea.pagingEnabled = FALSE; tArea.scrollEnabled = TRUE; tArea.backgroundColor = [UIColor clearColor]; [self.view addSubview:tArea]; ttextview = [[UITextView alloc] initWithFrame:CGRectMake(0, 0, 310, textsize.height + 20)]; ttextview.text = ttext; ttextview.font = [UIFont systemFontOfSize:20]; ttextview.backgroundColor = [UIColor clearColor]; ttextview.editable = NO; [tArea addSubview:ttextview]; But its no use. Looking for an elegant solution than this.

• How to document an accessor/mutator method in phpDoc/javaDoc?

  - by nickf

  Given a function which behaves as either a mutator or accessor depending on the arguments passed to it, like this: // in PHP, you can pass any number of arguments to a function... function cache($cacheName) { $arguments = func_get_args(); if (count($arguments) >= 2) { // two arguments passed. MUTATOR. $value = $arguments[1]; // use the second as the value $this->cache[$cacheName] = $value; // *change* the stored value } else { // 1 argument passed, ACCESSOR return $this->cache[$cacheName]; // *get* the stored value } } cache('foo', 'bar'); // nothing returned cache('foo') // 'bar' returned How do you document this in PHPDoc or a similar automated documentation creator? I had originally just written it like this: /** * Blah blah blah, you can use this as both a mutator and an accessor: * As an accessor: * @param $cacheName name of the variable to GET * @return string the value... * * As a mutator: * @param $cacheName name of the variable to SET * @param $value the value to set * @return void */ However, when this is run through phpDoc, it complains because there are 2 return tags, and the first @param $cacheName description is overwritten by the second. Is there a way around this?

• In Netbeans+Ant, how do I avoid wsimport rebuilding web service clients every build?

  - by gustafc

  I'm on a project where we use NetBeans (6.8). We use several different web services, which we have added as web service references, and Netbeans auto-generates the Ant wsimport scripts for us. Very handy, with one drawback: The web service clients are recompiled every time ant is invoked. This slows down the build process considerably and has caused the number of sword-related injuries, maimings and deaths to skyrocket. Normally, I'd fix this by changing the wsimport element from <wsimport sourcedestdir="${build.generated.dir}/jax-wsCache/PonyService" destdir="${build.generated.dir}/jax-wsCache/PonyService" wsdl="${wsdl-PonyService}" catalog="catalog.xml" verbose="true"/> to <wsimport sourcedestdir="${build.generated.dir}/jax-wsCache/PonyService" destdir="${build.generated.dir}/jax-wsCache/PonyService" wsdl="${wsdl-PonyService}" catalog="catalog.xml" verbose="true"> <produces dir="${build.generated.dir}/jax-wsCache/PonyService" /> </wsimport> But I can't, 'cause this part of the Ant script is auto-generated. If I right-click the PonyService web service reference and select Edit Web Service Attributes ⇒ wsimport options, I can add attributes to the wsimport element, but not child elements. So: How do I add the produces child element to wsimport other than hacking the auto-generated Ant script? Or more generally: How do I make the NetBeans-generated wsimport not recompile the web service clients every time I build?

• Objective-C Implementation Pointers

  - by Dwaine Bailey

  Hi, I am currently writing an XML parser that parses a lot of data, with a lot of different nodes (the XML isn't designed by me, and I have no control over the content...) Anyway, it currently takes an unacceptably long time to download and read in (about 13 seconds) and so I'm looking for ways to increase the efficiency of the read. I've written a function to create hash values, so that the program no longer has to do a lot of string comparison (just NSUInteger comparison), but this still isn't reducing the complexity of the read in... So I thought maybe I could create an array of IMPs so that, I could then go something like: for(int i = 0; i < [hashValues count]; i ++) { if(currHash == [[hashValues objectAtIndex:i] unsignedIntValue]) { [impArray objectAtIndex:i]; } } Or something like that. The only problem is that I don't know how to actually make the call to the IMP function? I've read that I perform the selector that an IMP defines by going IMP tImp = [impArray objectAtIndex:i]; tImp(self, @selector(methodName)); But, if I need to know the name of the selector anyway, what's the point? Can anybody help me out with what I want to do? Or even just some more ways to increase the efficiency of the parser...

• How can I highlight the corresponding titles of clicked links?

  - by danielle

  I'm writing an XSL file that contains a side-nav menu with a list of links. When the user clicks on one of the links, the page jumps to the corresponding table of information for that link. How can I make it so that when the link is clicked, the title of that table (not the link itself) is highlighted? It should also un-highlight if another link is clicked. Here is the menu of links: <div onclick = "highlight(this);" onblur = "undoHighlight(this);"> <a href = "#{generate-id(.)}"> <xsl:value-of select = "."/> (<xsl:value-of select = "count(../n1:entry)"/>) </a> </div> This is the javascript for the highlight/undoHighlight functions: function highlight(link) { undoHighlight(link) link.style.background = "red"; } function undoHighlight(link) { link.style.background = "white"; } Any help would be appreciated. Thanks in advance!

• Merging datasets based on 2 variables in SAS.

  - by John

  Hye Guys, my question is the following, i'm working with different databases, all contain information about 1000+ companies, a company is defined by its ticker code (the short version of the name( Ford as F) usually seen on stock quotation boards). Aside from the ticker code to merge on I also have to merge on the time, I used month as a count variable throughout my time series. The final purpose is to have a regression in the kind of Y(jt) = c + X(jt) +X1(jt) etc with j = company (ticker) and t = time (month). So imagine I have 2 databases, one which is the base database with variables such as Tickers, months, beta's of a company (risk measure) etc and a second database which has an extra variable (let's say market capitalisation). What I want to do then is to merge these 2 databases based on the ticker and the month. Example: Base database: Ticker __ Month __ Betas AA __ 4 __ 1.2 BB __ 8 __ 1.18 Second database: Ticker __ Month __ MCAP AA __ 4 __ 8542 BB __ 6 __ 1245 Then after merge I would like to have something like this: Ticker __ Month _ Betas ___ MCAP AA __ 4 _ 1.2 ___ 8542 So all observations that do not match BOTH date and ticker have to be dropped, I'm sure this is possible, just can't find the right type of code. Thanks! PS: I'm guessing the underscars have something to do with font layout but both the bold as italic is supposed to be normal :)

• Fun things you can do by mutating Java strings

  - by polygenelubricants

  So I've come around since I asked how to limit setAccessible to only “legitimate” uses and have come to embrace its power for fun. Enabled by its power, of course, is string mutation. import java.lang.reflect.Field; public class Mutator { static void mutate(Object obj, String field, Object newValue) { try { Field f = obj.getClass().getDeclaredField(field); f.setAccessible(true); f.set(obj, newValue); } catch (Exception e) { } } public static void mutate(String from, String to) { mutate(from, "value", to.toCharArray()); mutate(from, "count", to.length()); } public static void main(String args[]) { Mutator.mutate(System.getProperty("line.separator"), "<br/>\n"); System.out.println("Hello world!"); Mutator.mutate(Integer.toString(Integer.MIN_VALUE), "OMG!"); System.out.println(-2147483648); Mutator.mutate(String.valueOf((Object) null), "LOL!"); System.out.println(Arrays.toString(new int[3][])); Mutator.mutate(Arrays.toString(new int[0]), ":("); System.out.println(Arrays.toString(new byte[0])); } } Output (if no exception is thrown): Hello world!<br/> OMG!<br/> [LOL!, LOL!, LOL!]<br/> :(<br/> Let's see what other fun things we can come up with.

• Mysterious extra hashtable entry

  - by Harm De Weirdt

  Good evening everyone, I'm back :) Let me explain my problem. I have a hashtable in wich I store the products a costumors buys (%orders). It uses the productcode as key and has a reference to an array with the other info as value. At the end of the program, I have to rewrite the inventory to the updated version (i.e. subtract the quantity of the bought items) This is how I do this: sub rewriteInventory{ open(FILE,'>inv.txt'); foreach $key(%inventory){ print FILE "$key\|$inventory{$key}[0]\|$inventory{$key}[1]\|$inventory{$key}[2]\n" } close(FILE); } where $inventory{$key}[x] is 0 - Title, 1 - price, 2 - quantity. The problem here is that when I look at inv.txt afterwards, I see things like this: CD-911|Lady Gaga - The Fame|15.99|21 ARRAY(0x145030c)||| BOOK-1453|The Da Vinci Code - Dan Brown|14.75|12 ARRAY(0x145bee4)||| Where do these "ARRAY(0x145030c)|||" entries come from? Or more important, how do I get rid of them? This is the last part of this school task, I had so much problems programming all this and this stupid little thing comes up now and I'm really fed up with this whole Perl thing. (this aside :p) I hope someone can help me :) Fuji

• FLEX: the custom component is still a Null Object when I invoke its method

  - by Patrick

  Hi, I've created a custom component in Flex, and I've created it from the main application with actionscript. Successively I invoke its "setName" method to pass a String. I get the following run-time error (occurring only if I use the setName method): TypeError: Error #1009: Cannot access a property or method of a null object reference. I guess I get it because I'm calling to newUser.setName method from main application before the component is completely created. How can I ask actionscript to "wait" until when the component is created to call the method ? Should I create an event listener in the main application waiting for it ? I would prefer to avoid it if possible. Here is the code: Main app ... newUser = new userComp(); //newUser.setName("name"); Component: <?xml version="1.0" encoding="utf-8"?> <mx:VBox xmlns:mx="http://www.adobe.com/2006/mxml" width="100" height="200" > <mx:Script> <![CDATA[ public function setName(name:String):void { username.text = name; } public function setTags(Tags:String):void { } ]]> </mx:Script> <mx:HBox id="tagsPopup" visible="false"> <mx:LinkButton label="Tag1" /> <mx:LinkButton label="Tag2" /> <mx:LinkButton label="Tag3" /> </mx:HBox> <mx:Image source="@Embed(source='../icons/userIcon.png')"/> <mx:Label id="username" text="Nickname" visible="false"/> </mx:VBox> thanks

• Debug NAudio MP3 reading difference?

  - by Conrad Albrecht

  My code using NAudio to read one particular MP3 gets different results than several other commercial apps. Specifically: My NAudio-based code finds ~1.4 sec of silence at the beginning of this MP3 before "audible audio" (a drum pickup) starts, whereas other apps (Windows Media Player, RealPlayer, WavePad) show ~2.5 sec of silence before that same drum pickup. The particular MP3 is "Like A Rolling Stone" downloaded from Amazon.com. Tested several other MP3s and none show any similar difference between my code and other apps. Most MP3s don't start with such a long silence so I suspect that's the source of the difference. Debugging problems: I can't actually find a way to even prove that the other apps are right and NAudio/me is wrong, i.e. to compare block-by-block my code's results to a "known good reference implementation"; therefore I can't even precisely define the "error" I need to debug. Since my code reads thousands of samples during those 1.4 sec with no obvious errors, I can't think how to narrow down where/when in the input stream to look for a bug. The heart of the NAudio code is a P/Invoke call to acmStreamConvert(), which is a Windows "black box" call which I can't think how to error-check. Can anyone think of any tricks/techniques to debug this?

• Drupal: Template Files, Modules and Content Types for Advanced Theme

  - by theandym

  Intro I am in the process of trying to convert my first HTML/CSS design into a theme for Drupal. I have used ModX for quite a few designs and appreciate the ability to create different page templates and custom variables to be assigned to those templates. However I seem to be having some issues making the transition. The site I am working on theming in Drupal is for a real estate agent. Each page/section will have a different set of content associated with it and will need to display only that content. For example, there will be a page for current listings, each of which will be formatted by a custom content type. However, when I call the content on the home page (or on other pages) I do not want to see this listing data. Layout The layout of the site and the regions associated with each page/section is as follows: Home Spotlight Featured 1 Featured 2 About Spotlight Bios - Profiles of each agent (each will be a node with name, contact info, pic, etc) listed on the page; multiple nodes listed Sidebar Listings Spotlight Listings - Profiles of properties (each will be a node with locations, basic info, pic, etc) listed on the page; multiple nodes listed Sidebar Services Spotlight Content - general paragraph text area Sidebar News/Blog News/Blog Items - List of stories with summaries and links to full article Sidebar Each page/section will use the same header and footer. Issue I have done some reading on Drupal, custom content types (and CCK), Views, and Pathauto. However I have not been able to get a clear picture of how to put it all together to accomplish what I am attempting. What I really would like to know is which modules to use, how best to use them, which elements I need to use where, and what template files I should be using to theme the elements I need to use. Any help or reference to useful resources would be much appreciated.

• Automatic web form testing/filling

  - by Polatrite

  I recently became lead on getting an inordinate amount of testing done in a very short period of time. We have many different web forms, using custom (Telerik) controls that need to be tested for proper data validation and sensible handling of the data. Some of the forms are several pages long with 30-80 different controls for data entry. I am looking for a software solution (that is free) that would allow me to automate the process of filling in these forms by designing a script, or using a UI. The other requirement is that I can't use any browsers but IE6 (terrible, I know). I have previously used AutoHotkey to great success for automatic Windows form testing, since Autohotkey's API allows you to directly reference controls on the Windows form. However Autohotkey does not have similar support for web forms (everything is just one big "InternetExplorer" control). While I would prefer that I could script some variance in the data to help serialize each test, it's not necessary, as I could go back through and manually edit a field or two (plus "break" whatever control I'm currently testing) to serialize each test. If you've ever seen Spawner: http://forge.mysql.com/projects/project.php?id=214 It's almost exactly the sort of thing I'm looking for (Spawner generates dummy SQL data, as opposed to dummy webform data) - but I won't be picky, I've got a really short deadline to meet and had this thrust in my lap just today. ;) Edit1: One of the challenges of just using Autohotkey to simulate keyboard input (tabbing through controls) is that some controls don't currently have tab index (bug), and some controls cause a page reload after modification, resulting in inconsistent control focus (tabbing screwed up). Our application makes heavy use of page reloads to populate fields (select a location, it auto-populates a city, for example).

• Binding event handlers to specific elements, using bubbling (JavaScript/jQuery)

  - by Bungle

  I'm working on a project that approximates the functionality of Firebug's inspector tool. That is, when mousing over elements on the page, I'd like to highlight them (by changing their background color), and when they're clicked, I'd like to execute a function that builds a CSS selector that can be used to identify them. However, I've been running into problems related to event bubbling, and have thoroughly confused myself. Rather than walk you down that path, it might make sense just to explain what I'm trying to do and ask for some help getting started. Here are some specs: I'm only interested in elements that contain a text node (or any descendant elements with text nodes). When the mouse enters such an element, change its background color. When the mouse leaves that element, change its background color back to what it was originally. When an element is clicked, execute a function that builds a CSS selector for that element. I don't want a mouseover on an element's margin area to count as a mouseover for that element, but for the element beneath (I think that's default browser behavior anyway?). I can handle the code that highlights/unhighlights, and builds the CSS selector. What I'm primarily having trouble with is efficiently binding event handlers to the elements that I want to be highlightable/clickable, and avoiding/stopping bubbling so that mousing over a (<p>) element doesn't also execute the handler function on the <body>, for example. I think the right way to do this is to bind event handlers to the document element, then somehow use bubbling to only execute the bound function on the topmost element, but I don't have any idea what that code looks like, and that's really where I could use help. I'm using jQuery, and would like to rely on that as much as possible. Thanks in advance for any guidance!

  Hi, I'm trying to create a file which has the following structure: - Each line has 32 bytes - Each line looks like this format string: "%10i %3.7f %3.7f\n" My Problem is the following: When i have a negative floating point numbers the line gets longer by one or even two characters because the - sign does not count to the "%3.7f". Is there any way to do this more nicely than this? if( node->lng > 0 && node->lat > 0 ) { sprintf( osm_node_repr, "%10i %3.7f %3.7f\n", node->id, node->lng, node->lat ); } else if (node->lng > 0 && node->lat < 0) { sprintf( osm_node_repr, "%10i %3.7f %3.6f\n", node->id, node->lng, node->lat ); } else if (node->lng < 0 && node->lat > 0) { sprintf( osm_node_repr, "%10i %3.6f %3.7f\n", node->id, node->lng, node->lat ); } else if ( node->lng < 0 && node->lat < 0 ) { sprintf( osm_node_repr, "%10i %3.6f %3.6f\n", node->id, node->lng, node->lat ); } Thanks for your Answers, Andreas

• ASP.Net HttpModule List<> content

  - by test

  We have created an http module that loads data on initialize into a list, and uses that list on every endrequest event of application. However we got a null reference exception on the module at endRequest event complaining that the content is null. Yet we are sure that at module initialization we have put non-null objects correctly. How is this possible? Any ideas? Thanks in advance. The place where i fill the data into the list what named as "Pages" : using (SqlDataReader reader = cmd.ExecuteReader()) { while (reader.Read()) { LandingPageDetails details = new LandingPageDetails(); details.DomainId = Convert.ToInt32(reader["DomainId"]); details.PageId = Convert.ToInt32(reader["TrackingPageId"]); details.PageAddress = Convert.ToString(reader["PageAddress"]); if (!string.IsNullOrEmpty(details.PageAddress)) { Pages.Add(details); } } } // Find the related record on EndRequesst event LandingPageDetails result = Pages.Find ( delegate(LandingPageDetails current) { return current.PageAddress.Equals(url, StringComparison.InvariantCultureIgnoreCase); } ); The line what we get the error return current.PageAddress.Equals(url, StringComparison.InvariantCultureIgnoreCase); "current" is the null object P.S : It works properly, but one day later contents become null. Possibly, there is something wrong on IIS. Our server is Windows 2003, IIS 6.0

• how to access control in templatefield gridview with custom id

  - by Mohsen.Tavoosi

  i have a customized gridview.my grid is able to sort for each column just by 1 click in the header without any setting and overloading methods such as sorting,etc by user(programmer).(i do this successfully and work fine) users(programmers) maybe add each column in grid.such as template field,hyperlinkfield,boundfield... . for sorting, i must access datafield of columns. i can access boundfield column by this code.i can access datafield and header text and ... sample: for (int j = 0; j < this.Columns.Count; j++) { BoundField bf; bf = this.Columns[j] as BoundField; if (bf != null) { string ht = bf.HeaderText; string df = bf.DataField; } } but i can access control in the templateField.such as ColumnBound. sample: <asp:Label ID="Label1" runat="server" Text='<%# Bind("Name") %>'></asp:Label> i want access "Name" (Bind ("Name") or Eval ("Name")) . how can i? there is a point: i dont now what is the ID (in this case "Label1") of control in templatefield. special thanks

• Accessing items separated by -componentsSeparatedByString

  - by Graeme

  Hi, I have an array gathered by componentsSeparatedByString: that looks like the following when I use po in the GDB after the array has gone through componentsSeparatedByString: "\n\t\t <b>Suburb, </b> BAIRNSDALE", "\n\t\t <b>Address, </b> 15K NW BAIRNSDALE", "\n\t\t <b>Reference, </b> MELWOOD/SCHOOL ROAD", "\n\t\t <b>Last Changed, </b> 09/04/10 05, 29, 00 PM", "\n\t\t <b>Type, </b> HOME", "\n\t\t <b>Status, </b> BUILT", "\n\t\t <b>Property Size, </b> 2.00 HA.", "\n\t\t <b>Residents, </b> 2", "\n\t\t <b>First Added Date/Time, </b> 09/04/10 03, 15, 00 PM", "\n\t\t\t" Only problem is, I now can't figure out where to go from here. I need to be able to access each of these items (i.e. type, status, property size) separately rather than just calling the entire array (i.e. currentProperty.status). How do I do this? Also what's with all the n\t\t\t things - how do I get rid of them? Thanks.

• How to push this view controller ?

  - by hib

  Hello all, I am caught in a strange requirement .See the following view hierarchy and scenario . I have a tab bar application in which I have three tabs . In first tab I am showing some content with a small image title and date (uitableview in navigation controller). In the detail view of that controller there are more buttons that shows different sorts of detail like gallery button and , more details button and some , more button . On tapping each button I will push each individual view controller in the main navigation controller . Now on the horizontal orientation I am showing same list of content but in the cover flow ( in modal view controller ) fashion like the ipod application . On tapping any image we will show the same buttons like gallery and more details and tapping on it will show the new controller with the following code : UINavigationController *modalNavController = [[UINavigationController alloc] initWithRootViewController:myPhotoController]; UIBarButtonItem *backButton = [[UIBarButtonItem alloc] initWithTitle:@"Back" style:UIBarButtonItemStyleBordered target:self action:@selector(backButtonPressed)]; myPhotoController.navigationItem.leftBarButtonItem = backButton; [backButton release]; if([self.modalViewController isViewLoaded]){ [self dismissModalViewControllerAnimated:YES]; } modalNavController.navigationBar.barStyle = UIBarStyleBlackOpaque; [self presentModalViewController:modalNavController animated:YES]; [modalNavController release]; All this is working nicely . but when I get back the device in vertical orientation . the main modal controller will be dismissed and all the containing modal controller also will be dismissed if they are open or not . Instead of this what I want is If chooses an item in the coverflow and then if chooses gallery and if I put the device in vertical orientaion the gallery should be in the navigation hierarchy that drove me to the main list and gallery should be in horizonatal fashion . So what I want to do is that just to push the gallery controller in the main navigation hierarchy instead of showing from a madal controller . If someone wants reference then see the application "net a porter" I want to do like that . Just tell me how the controller hierarchy is working in that app . I need the help . Thanks
