  • Using Simple XML and getting NoClassDefFoundError in Android

    - by Berat Onur Ersen
    I'm trying to use Simple XML to convert my java objects to XML format in my Android application. I'm getting NoClassDefFoundError at line Serializer serializer = new Persister(); java.lang.NoClassDefFoundError: org.simpleframework.xml.core.Persister I have simple-xml-2.6.1.jar in project class path and when I got NoClassDefFoundError I also put these 3 jars in classpath stax-1.2.0.jar stax-api-1.0.1.jar xpp3-1.1.3_8.jar but made no use. Still having NoClassDefFoundError. Any kind of help will be appreciated.Thank you.

  • WPF DataGrid DataGridHyperlinkColumn bound to Uri

    - by MicMit
    No problem when binding to a property of string type ( "http://something.com" ). However , I seem to have seen in old examples direct binding to Uri property. <dg:DataGridHyperlinkColumn IsReadOnly="True" Header="Uri" Binding="{Binding Path=NavigURI}" /> NavigURI is Uri . More recent docs seem to require a converter <DataGridHyperlinkColumn Header="Email" Binding="{Binding Email}" ContentBinding="{Binding Email, Converter={StaticResource EmailConverter}}" /> I tried with a converter also, but in both cases with or without converter column is empty. Debugging showed that value passed to "Convert" method is always null. My question : if for any reason I want binding to Uri property , is it feasible for the latest DataGrid from Codeplex ?

  • Fancy dynamic list in Android: TableLayout vs ListView

    - by Ralkie
    There is a requirement to have not-so-trivial dynamic list, each record of which consists of several columns (texts, buttons). It should look something like: Text11 Text12 Button1 Button2 Text21 Text22 Button1 Button2 ... At first obvious way to accomplish that seemed to be TableLayout. I was expecting to have layout/styling data specified in res/layout/*.xml and to populate it with some dataset from java code (as with ListView, for which its possible to specify TextView of item in *.xml and bind it to some array using ArrayAdapter). But after playing for a while, all I found to be possible is fully populating TableLayout programatically. Still, creating TableRow by TableRow and setting layout attributes directly in java code doesn't seem elegant enough. So the questions are: Am I at the right path? Is TableLayout really best View to accomplish that? Maybe it's more appropriate to extend ListView or something else to meet such requirements? Is it possible to have TableLayout/TableRow template specified in *.xml and data bound to this template in java side?

  • Android "application stopped unexpectedly" - google Hello MapView Tutoria

    - by Cookie
    Hi, I'm trying the Hello MapView Tutorial at the moment. Whe I launch the program in the emulator, I get a huge number of errors (none of the exceptions seems to be related with lines in my code). The emulator window tells the program "stopped unexpectedly". Can anybody tell me which is the key line in the error output?

  • MSBuild cannot find SGen when compiling a solution

    - by Jaxidian
    I've looked at several other SGen-related questions on here and either their answers don't apply or their answers don't fix this for me. I have installed several SDKs to fix this issue with no luck. Reference types should not be changed since this is the only place this is a problem. Once suggestion is to put SGen.exe into the C:\Windows\Microsoft.NET\Framework\v3.5 folder, but that's not been done on the box where this is not a problem. In this scenario, SGen.exe actually exists and is right where it's supposed to be, but MSBuild still is having issues with finding it for some reason! Background: We have a NAnt script that automates our builds. In this scenario, NAnt is calling MSBuild and MSBuild is generating the error claiming to be unable to find SGen. The project is .NET 3.5-based. I have my primary dev environment (64-bit Vista Ultimate) where the script works perfectly and I am attempting to duplicate it in a VM (64-bit Win 7 Ultimate). I THINK I have everything to the point where I should be good-to-go but this fails on the Win7 box (works perfectly on the Vista box). I have done some comparisons between the two boxes and they both look identical in this regard, but it still fails. For example, the HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework's sdkInstallRootv2.0 value is set to C:\Program Files\Microsoft.NET\SDK\v2.0 64bit\ on both machines. In both machines, SGen.exe is in that path's bin subdirectory. NAnt Script: <target name="report-installer" depends="fail-if-environment-not-set"> <exec program="MSBuild.exe" basedir="${framework35.directory}"> <arg value="${tools.directory.current}\ReportInstaller\ReportInstaller.sln" /> <arg value="/p:Configuration=${buildconfiguration.current}" /> </exec> </target> The error message I get is this: report-installer: [exec] Microsoft (R) Build Engine Version 3.5.30729.4926 [exec] [Microsoft .NET Framework, Version 2.0.50727.4927] [exec] Copyright (C) Microsoft Corporation 2007.

  • Flash Player 10.1 crash on shared object access

    - by Simon
    Hi all, since updating my Flash Player plugin from 10 to 10.1, I'm seeing a weird crash when accessing shared objects. Flex Builder's debugger pops up and prints a stack trace like this: undefined at flash.net::SharedObject$/getLocal() at my.code::MyClass$/load()[/my/path/to/my/MyClass.as:27] (...) This happens when calling SharedObject.getLocal("someString") for the second time for the same string, though it doesn't always crash. When using another browser on the same machine (not configured as the preferred debugging browser in Flex Builder), Flash Player remains silent. The code is wrapped in a try/catch(Error) block which does not catch this error. I'm using Flex SDK 3.5 and Flex Builder 3 on Mac OS X 10.6.3. Has anyone else seen this? Thanks, Simon

  • Optimized Image Loading in a UIScrollView

    - by Michael Gaylord
    I have a UIScrollView that has a set of images loaded side-by-side inside it. You can see an example of my app here: http://www.42restaurants.com. My problem comes in with memory usage. I want to lazy load the images as they are about to appear on the screen and unload images that aren't on screen. As you can see in the code I work out at a minimum which image I need to load and then assign the loading portion to an NSOperation and place it on an NSOperationQueue. Everything works great apart from a jerky scrolling experience. I don't know if anyone has any ideas as to how I can make this even more optimized, so that the loading time of each image is minimized or so that the scrolling is less jerky. - (void)scrollViewDidScroll:(UIScrollView *)scrollView{ [self manageThumbs]; } - (void) manageThumbs{ int centerIndex = [self centerThumbIndex]; if(lastCenterIndex == centerIndex){ return; } if(centerIndex >= totalThumbs){ return; } NSRange unloadRange; NSRange loadRange; int totalChange = lastCenterIndex - centerIndex; if(totalChange > 0){ //scrolling backwards loadRange.length = fabsf(totalChange); loadRange.location = centerIndex - 5; unloadRange.length = fabsf(totalChange); unloadRange.location = centerIndex + 6; }else if(totalChange < 0){ //scrolling forwards unloadRange.length = fabsf(totalChange); unloadRange.location = centerIndex - 6; loadRange.length = fabsf(totalChange); loadRange.location = centerIndex + 5; } [self unloadImages:unloadRange]; [self loadImages:loadRange]; lastCenterIndex = centerIndex; return; } - (void) unloadImages:(NSRange)range{ UIScrollView *scrollView = (UIScrollView *)[[self.view subviews] objectAtIndex:0]; for(int i = 0; i < range.length && range.location + i < [scrollView.subviews count]; i++){ UIView *subview = [scrollView.subviews objectAtIndex:(range.location + i)]; if(subview != nil && [subview isKindOfClass:[ThumbnailView class]]){ ThumbnailView *thumbView = (ThumbnailView *)subview; if(thumbView.loaded){ UnloadImageOperation *unloadOperation = [[UnloadImageOperation alloc] initWithOperableImage:thumbView]; [queue addOperation:unloadOperation]; [unloadOperation release]; } } } } - (void) loadImages:(NSRange)range{ UIScrollView *scrollView = (UIScrollView *)[[self.view subviews] objectAtIndex:0]; for(int i = 0; i < range.length && range.location + i < [scrollView.subviews count]; i++){ UIView *subview = [scrollView.subviews objectAtIndex:(range.location + i)]; if(subview != nil && [subview isKindOfClass:[ThumbnailView class]]){ ThumbnailView *thumbView = (ThumbnailView *)subview; if(!thumbView.loaded){ LoadImageOperation *loadOperation = [[LoadImageOperation alloc] initWithOperableImage:thumbView]; [queue addOperation:loadOperation]; [loadOperation release]; } } } } EDIT: Thanks for the really great responses. Here is my NSOperation code and ThumbnailView code. I tried a couple of things over the weekend but I only managed to improve performance by suspending the operation queue during scrolling and resuming it when scrolling is finished. Here are my code snippets: //In the init method queue = [[NSOperationQueue alloc] init]; [queue setMaxConcurrentOperationCount:4]; //In the thumbnail view the loadImage and unloadImage methods - (void) loadImage{ if(!loaded){ NSString *filename = [NSString stringWithFormat:@"%03d-cover-front", recipe.identifier, recipe.identifier]; NSString *directory = [NSString stringWithFormat:@"RestaurantContent/%03d", recipe.identifier]; NSString *path = [[NSBundle mainBundle] pathForResource:filename ofType:@"png" inDirectory:directory]; UIImage *image = [UIImage imageWithContentsOfFile:path]; imageView = [[ImageView alloc] initWithImage:image andFrame:CGRectMake(0.0f, 0.0f, 176.0f, 262.0f)]; [self addSubview:imageView]; [self sendSubviewToBack:imageView]; [imageView release]; loaded = YES; } } - (void) unloadImage{ if(loaded){ [imageView removeFromSuperview]; imageView = nil; loaded = NO; } } Then my load and unload operations: - (id) initWithOperableImage:(id<OperableImage>) anOperableImage{ self = [super init]; if (self != nil) { self.image = anOperableImage; } return self; } //This is the main method in the load image operation - (void)main { [image loadImage]; } //This is the main method in the unload image operation - (void)main { [image unloadImage]; }

  • Ndk-build: CreateProcess: make (e=87): The parameter is incorrect

  • WPF: Binding Combobox in Code Behind to Property

    - by Richard
    Hi All, This might be something very straight forward and I really think it should work as is, but it doesn't... I have the following scenario: var itemSource = new Binding { Path = new PropertyPath("ItemList"), Mode = BindingMode.OneTime }; comboBox.SetBinding(ItemsControl.ItemsSourceProperty, itemSource); ItemList is simply: public IList<string> ItemList { get { return Enum.GetNames(typeof(OptionsEnum)).ToList(); } } I would have expected this to bind the list of items to the Combobox, and when I do it in XAML it works fine, but I have to do it in code behind... Any ideas?

  • Oracle Open World 2012: SQL Developer Recap

    - by thatjeffsmith
    Last week was the ‘big show’ in San Francisco. I was very happy to meet many of you in person. And many of you had questions – lots of questions! We had full or overflowing rooms for our sessions and hands-on-labs. The SQL Developer ‘booths’ were also slammed several times. So exciting to see so many of YOU excited about SQL Developer. It’s very cool to hear the stories of our tools saving you and your organizations so much time (and money!) Instead of doing a Day 0 – Day 9 recap, I thought I’d share with you the questions that I heard more than once. And just for giggles, I’ll throw in some answers as well So in no particular order… What’s the difference between Oracle SQL Developer & Oracle SQL Developer Data Modeler? Mathematically speaking – two words. But as far as the actual modeling features go, there’s no difference between the two applications. The same ‘code’ or features as it pertains to data modeling and design are in both tools. However, in SQL Developer you have all of the OTHER features fighting for real estate in the UI. So I have a general rule of thumb – if you spend MOST of your time in the database, use SQL Developer. And if you spend most of your time in the data model, run the separate and dedicated program, Oracle SQL Developer Data Modeler. Here’s a couple of screenshots to drive home the UI point: Oracle SQL Developer Oracle SQL Developer Data Modeler running INSIDE of SQL Developer. Notice how the Modeler menu items fold under the file menu? Oracle SQL Developer Data Modeler Easier to navigate and manipulate your models with the stand alone modeler. Just no worksheet to run your ad-hoc queries, etc. Don’t forget you can disable the Data Modeler inside of SQL Developer via the Extensions preference page. How can I model my table partitions? Partitioning is defined via the Physical model. So after you have finished your relational model, you need to generate a physical model. Oracle SQL Developer Data Modeler Physical Model and Partitioning Open the properties for your physical model table. Enable the ‘partitioned’ property. Once you do so, the ‘Partitioning’ page will activate. Lots and lots of partitioning support and options here But what about Interval Partitioning? An extension of range partitioning in 11gR2, we don’t currently support this partitioning scheme in SQL Developer. But we’re working on it! Can SQL Developer ignore column order when comparing models? Yes! After you start a model compare, one of your options is to disregard the order of an attribute or column definition. Tell SQL Developer you don’t care when your column shows up, just as long as it DOES show up. Wow, you got a lot of questions around modeling! Is that normal? Yes! While we appreciate that many folks inherit their applications and associated designs, new applications are being ‘born’ every day. Since both of our tools are free for anyone to design their new Oracle applications with, we attract a fair amount of attention I want to do a Hands On Lab. How do I get your software and instructional guides? Go here. Download VirtualBox. Then download the VB image. Import the appliance. Start it. Connect oracle/oracle on the OEL VM. Click on ‘Start Here’ in the desktop. Follow the instructions. If you need help, ask away! You went too fast in your Tips & Tricks session. Do you have cliff notes? Yes! And you’re SO close to finding them! Just go to my SQL Developer resources page. All of my tips are documented on this blog somewhere. I’ve indexed the most popular ones on the resource page. You can use the Search dialog on the right to find the rest. Or just send me a comment or question, and I’ll do my best to answer them as they come in.

  • Form, function and complexity in rule processing

    - by Charles Young
    Tim Bass posted on ‘Orwellian Event Processing’. I was involved in a heated exchange in the comments, and he has more recently published a post entitled ‘Disadvantages of Rule-Based Systems (Part 1)’. Whatever the rights and wrongs of our exchange, it clearly failed to generate any agreement or understanding of our different positions. I don't particularly want to promote further argument of that kind, but I do want to take the opportunity of offering a different perspective on rule-processing and an explanation of my comments. For me, the ‘red rag’ lay in Tim’s claim that “...rules alone are highly inefficient for most classes of (not simple) problems” and a later paragraph that appears to equate the simplicity of form (‘IF-THEN-ELSE’) with simplicity of function.   It is not the first time Tim has expressed these views and not the first time I have responded to his assertions.   Indeed, Tim has a long history of commenting on the subject of complex event processing (CEP) and, less often, rule processing in ‘robust’ terms, often asserting that very many other people’s opinions on this subject are mistaken.   In turn, I am of the opinion that, certainly in terms of rule processing, which is an area in which I have a specific interest and knowledge, he is often mistaken. There is no simple answer to the fundamental question ‘what is a rule?’ We use the word in a very fluid fashion in English. Likewise, the term ‘rule processing’, as used widely in IT, is equally difficult to define simplistically. The best way to envisage the term is as a ‘centre of gravity’ within a wider domain. That domain contains many other ‘centres of gravity’, including CEP, statistical analytics, neural networks, natural language processing and so much more. Whole communities tend to gravitate towards and build themselves around some of these centres. The term 'rule processing' is associated with many different technology types, various software products, different architectural patterns, the functional capability of many applications and services, etc. There is considerable variation amongst these different technologies, techniques and products. Very broadly, a common theme is their ability to manage certain types of processing and problem solving through declarative, or semi-declarative, statements of propositional logic bound to action-based consequences. It is generally important to be able to decouple these statements from other parts of an overall system or architecture so that they can be managed and deployed independently.  As a centre of gravity, ‘rule processing’ is no island. It exists in the context of a domain of discourse that is, itself, highly interconnected and continuous.   Rule processing does not, for example, exist in splendid isolation to natural language processing.   On the contrary, an on-going theme of rule processing is to find better ways to express rules in natural language and map these to executable forms.   Rule processing does not exist in splendid isolation to CEP.   On the contrary, an event processing agent can reasonably be considered as a rule engine (a theme in ‘Power of Events’ by David Luckham).   Rule processing does not live in splendid isolation to statistical approaches such as Bayesian analytics. On the contrary, rule processing and statistical analytics are highly synergistic.   Rule processing does not even live in splendid isolation to neural networks. For example, significant research has centred on finding ways to translate trained nets into explicit rule sets in order to support forms of validation and facilitate insight into the knowledge stored in those nets. What about simplicity of form?   Many rule processing technologies do indeed use a very simple form (‘If...Then’, ‘When...Do’, etc.)   However, it is a fundamental mistake to equate simplicity of form with simplicity of function.   It is absolutely mistaken to suggest that simplicity of form is a barrier to the efficient handling of complexity.   There are countless real-world examples which serve to disprove that notion.   Indeed, simplicity of form is often the key to handling complexity. Does rule processing offer a ‘one size fits all’. No, of course not.   No serious commentator suggests it does.   Does the design and management of large knowledge bases, expressed as rules, become difficult?   Yes, it can do, but that is true of any large knowledge base, regardless of the form in which knowledge is expressed.   The measure of complexity is not a function of rule set size or rule form.  It tends to be correlated more strongly with the size of the ‘problem space’ (‘search space’) which is something quite different.   Analysis of the problem space and the algorithms we use to search through that space are, of course, the very things we use to derive objective measures of the complexity of a given problem. This is basic computer science and common practice. Sailing a Dreadnaught through the sea of information technology and lobbing shells at some of the islands we encounter along the way does no one any good.   Building bridges and causeways between islands so that the inhabitants can collaborate in open discourse offers hope of real progress.

  • visual studio 2010: The Breakpoint will not currently be hit: No symbols have been loaded for this d

    - by Grayson Mitchell
    I am using VS2010, and Silverlight 4. When I run my code the debugging does not work (I get the above error on my breakpoints. When I clean my solution a warning comes up saying that the system cannot find the file specified (a project dll). It is looking in the right path (..\debug), but there is no dll present. I started a new Silverlight 4 project, and get the same error. Sometime's the debugging does work (I am not sure if/what anything changed, but on one occasion I was surprised that my breakpoints worked. After changing one thing the breakpoints stopped working)

  • .htaccess rewrite rule to add a string in the middle of the URL

    - by Mike Crittenden
    Using a .htaccess rewrite rule, I need to add "?q=" before the path on any URL's containing the word "imagecache" Therefore, if the URL is: http://mysite.com/sites/default/files/imagecache/myimage.jpg ...then it will really try: http://mysite.com/?q=sites/default/files/imagecache/myimage.jpg But that will ONLY happen if the URL contains "imagecache." Otherwise, it does no rewriting. Also, this will only happen if /sites/default/files/imagecache/myimage.jpg isn't already an existing image file. I believe I can do that using: RewriteCond %{REQUEST_FILENAME} !-f ...right? It's just the first part that I can't figure out.

  • XCOPY to remote server

    - by Max
    In order to improve the deployment / build process of my ASP.NET app, I would like to make a .bat that builds the current solution in release mode xcopy the files to a remote server Creating a release build via command line is easy. But how can I xcopy the files to the remote server? I think I have to map the remote destination to a network drive (?). However I could not connect to the remote server, although I have enabled file sharing for the folder on the server. Maybe the firewall is blocking the request? Which port should I open? Or is there another solution? EDIT Thanks for all the answers so far, but I probably need a step by step guide on how to set up the folder sharing on the server. I shared the folder, I opened up port 445 so that I can connect to the server but still, I cant connect from my local machine to the server in order to map the network path to a system drive.

  • windbg dv cmd fail - Private symbols (symbols.pri) are required for locals

    - by leif
    i have a C++ application compiled with VS 2008 with pdb file enabled. After i tried to use dv command to display local vars, it shows the following message: Unable to enumerate locals, HRESULT0x80004005 Private symbols (symbols.pri) are required for locals. Type ".hh dbgerr005" for details. Note that: i've run the "dv" command on the correct frame which has the symbol file. i can use "dt" command successfully. i've included the symbol path and the pdb file has been loaded successfully as following: start end module name 00400000 0043f000 helloworld (private pdb symbols) c:\test... Does anyone know the cause? Is there any configuration i missed to enable local var watch? Or VS 2008 pdb is not supported by windbg (i'm using the latest windbg version)?

  • ASP.NET MVC Areas: How to hide "Area" name in URL?

    - by Mark Redman
    When running the MVC 2 Areas example that has a Blog Area and Blog Controller the URL looks like this: http://localhost:50526/Blog/Blog/ShowRecent in the format: RootUrl / AreaName / ControllerName / ActionName Having just discovered MVC Areas, it seem like a great way to organise code, ie create an Area for each section, which in my case each section has its own controller. This means that each AreaName = ControllerName. The effect of this is the double AreaName/ControllerName path in the Url eg /Blog/Blog/ above Not having a complete clear understanding of routing, how could I setup routing to not show the AreaName?

  • Is there a way to avoid putting the Perl version number into the "use lib" line for Perl modules in

    - by Kinopiko
    I am trying to install some Perl modules into a non-standard location, let's call it /non/standard/location. In the script which uses the module, it seems to be necessary to specify a long directory path including the version of Perl, like so: #!/usr/local/bin/perl use lib '/non/standard/location/lib/perl5/site_perl/5.8.9/'; use A::B; Is there any use lib or other statement which I can use which is not so long and verbose, and which does not include the actual version of Perl, in order that I don't have to go back and edit this out of the program if the version of Perl is upgraded?
