  • Microsoft Enterprise Logging Application Block - Reading Log File

    - by Or A
    Hi, I'm using MS log application block for logging my application event into a file called app-trace.log which located on the c:\temp folder. I'm trying to find the best way to read this file at runtime and display it when the user asks for it. now i have 2 issues: it seems that this kind of feature is not supported by the framework, hence i have to write this reader myself. am i missing something here? is there any better way of getting this data (w/o buffering it in the memory or saving it into another file). if i'm taking the only alternative that left for me, and implementing the reader myself, when i'm tring to do: System.IO.FileStream fs = new System.IO.FileStream(@"c:\temp\app-trace.log", FileMode.Open, FileAccess.Read); i'm getting "File being used by another process c#", probably the file is locked by the application block. is there any way to access and read it anyhow? Thank

  • kCGImagePropertyIPTCKeywords problem

    - by deepa
    Hi, I am developing an iPhone app in which I want to set the keywords for an image using ImageIO.framework. Following is the code snippet that I use for setting the keywords. But, it does not apply the keywords to image meta data. Could some one help me out in finding the problem here. NSMutableDictionary *iptcDictionary = [NSDictionary dictionaryWithObject: [NSArray arrayWithObject: @"Test"] forKey:(NSString *)kCGImagePropertyIPTCKeywords]; NSDictionary *newImageProperties = [NSDictionary dictionaryWithObject:iptcDictionary forKey:(NSString *)kCGImagePropertyIPTCDictionary]; CGImageSourceRef imageSource=CGImageSourceCreateWithURL((CFURLRef)imageURL, nil); //imageURL is URL of source image CGImageDestinationRef imageDestination = CGImageDestinationCreateWithData( (CFMutableDataRef)newImageFileData, CGImageSourceGetType(imageSource), 1,NULL); CGImageDestinationAddImageFromSource(imageDestination, imageSource, 0, (CFDictionaryRef) newImageProperties); if (CGImageDestinationFinalize(imageDestination)) [newImageFileData writeToFile:imagePath atomically:YES]; //imagePath is the path of the destination image with new metadata Thanks and regards, Deepa

  • Obtaining command line arguments in a QT console app

    - by morpheous
    The following snippet is from a little console app I wrote using the QT framework. Currently, it does not receive the arguments passed at the CLI. Can anyone spot what I may be doing wrong? int main(int argc, char *argv[]) { //Q_INIT_RESOURCE(application); try { QApplication the_app(argc, argv); utility::option_values ov; QStringList cmdline_args = QCoreApplication::arguments(); //attempt to parse arguments here, but cmdline_args is an empty list :( ov.parse_options(cmdline_args); // Code continues ... } } catch (utility::invalid_option&) { return 1; } return 0; } I am debugging using QtCreator 1.3

  • Data Visualization Prototype (Java/Eclipse/DAO/Relational DB)

    - by Vince
    Hello, I am building a prototype application which displays various 2D & 3D data charts. I am using a third party library for the charts, the database and data extraction layer have already been coded. Can you advise on a good desktop Framework to use within Eclipse to provide a 'professional' looking GUI with minimum coding required (This is just a prototype). Further can anyone advise an effective method to port this application to a web server so users could access remotely? I have limited experience with GWT, are their more suitable alternatives? Many Thanks

  • A tool to determine jar dependencies based on existing code?

    - by geoffeg
    Is there a tool that can determine .jar dependencies given a directory of .jar files and a separate directory of java source code? I need to generate Eclipse .classpath files based on an existing code base that doesn't have any dependencies defined. To be more specific, I've been given a large codebase consisting of a dozen or so J2EE-style projects and a single directory of jar files. My client uses a custom development and build framework that is just too arcane for me to use and get any real work done. The projects do not have any information about their dependencies, either between projects or to jar libraries. I would expect this tool would have to spin through each jar file, indexing the classes available in that file and then go through each file in the project source code tree and match up the dependencies, possibly writing out a .classpath file with the required jar files. I realize this is a rather simplistic view of the operation, as duplicate classes among the jar files and such might make things more difficult.

    - by user290907
    Is there a framework which can be used in your application, to make it expose internal objects on some port for inspection. for.e.g. after i start my application in this case a GUI Application, and then say launch http://localhost:9100 then it should show me the statistics of the app. I played a bit with HttpListener accepting connections and then outputting raw HTML, it works fine for simple tasks, but there is too much worked involved if i have make a proper object browser. Thanks in Advance.

  • Passing Services to MainViewModel - SHOULD I use a dependency injection container ?

    - by msfanboy
    Hello, I have this code: public partial class App : Application { protected override void OnStartup(StartupEventArgs e) { base.OnStartup(e); var mainVM = new MainViewModel ( new Service1(), ... new Service10(), ); var window = new MainWindow(); window.DataContext = mainVM; window.Show(); } } I pass all my Services instances to the MainViewModel. Within the MainViewModel I spread those services to other ViewModels via constructor parameter passing. Should I use any DI framework for the services in the App class? If yes whats the benefit of resolving the services instead of just creating the instance manually... ?

  • Creating a Dynamic calendar in Silverlight

    - by Tom
    I am attempting to create a long range calendar that dynamically loads (and unloads) event data as the user scrolls left or right through time. I'm really struggling to figure out how to lay the basic framework of the UI out and how to dynamically build the interface as the user scrolls by clicking and dragging the mouse in the view area. See the image below for a basic diagram of the intent. Each slice would have potentially multiple rectangles in it for events that occurred on that day (slice). I would like each slice to be a canvas to allow me to position those rectangles appropriately. There are a few problems that I am not yet sure how to tackle but this is the first big one that I've been mulling over for a while and can't quite wrap my head around: I know how to dynamically create controls but how would I go about adding things to one end of the scrollable content while removing things from the other depending on the way the user is scrolling? Any guidance in the right direction would be much appreciated! Thanks.

  • Returning back to the results after editing

    - by Parhs
    Hello, I am developing an application which has several CRUD actions... I am using Java and i am forced to use Struts framework. My problem is: I have a search page which returns some results.The user can click at a result and then he goes to another edit-page... He may apply changes or not...What i need is a way to return at the result page again and at the same scroll position.Javascript must be enabled for this project however.. I am wondering which is the best practice to achieve this effect... A solution would be to save the last search URL but i know that this wouldnt work if the user has multiple results. I know how to do it but i am lloking for a good practice!

  • Avoiding try/catch hell in my web pages

    - by Shaun_web
    I am writing an ASP.NET website, which is a new framework for me. I find that I have a try/catch block in literally every method of my codebehind. All these try/catch blocks do is catch the exception and then pop-up an error message to the user. Isn't there some sort of global error handler in ASP.NET? It's worth noting that my error handling is within control (ASCX) pages, and I would like a way to simply get each ASCX to handle its own errors without forcing all error handling just to a single master page or a redirect...

  • How to load the content of a page into another window?

    - by Cristian Castiblanco
    I'm building a Dashboard and for some stupid reasons my boss wants to load it in a frame on the homepage (yes a frame, he still lives in the 1990s). Anyway, sometimes the dashboard needs some room so that it can show all charts correctly, so I want to add a feature to load the content of the dashboard into a new window. The problem is that, if the user has had some interaction with the dashboard, it will contain modal dialogs, new images, etc... so I want to load all the dashboard content into a new window without reloading its content. Of course, the user should be able to continue browsing the dashboard without problems. How can I do that? I'm using jQuery as my JavaScript framework.

  • Xcode OpenGL Build Error (header file not found)

    - by Strix Nebulosa
    When building my Objective-C project (for Mac OS 10.9, Xcode 5.11), I get the error message Lexical or Preprocessor Issue 'OpenGL/OpenGL.h' file not found. The error is caused by the include section of the file CVDisplayLink.h where the above named file is included. CVDisplayLink.h belongs to the framework CoreVideo. Now there are two strange points related to that issue: The error appeared after I tried to test some basic OpenGL features using the tutorial in the Mac Developer Library ( https://developer.apple.com/library/mac/documentation/GraphicsImaging/Conceptual/OpenGL-MacProgGuide/opengl_drawing/opengl_drawing.html#//apple_ref/doc/uid/TP40001987-CH404-SW8 ). I added an NSOpenGLView to my MainMenu as well as the related code given in the tutorial. Then the error message appeared. I also tried to add the OpenGL and CoreVideo frameworks to my project target, but this did not help. After some frustration, I removed the NSOpenGLView from my project, as well as all related code. Now the error Message still appeares and I have no Idea how to ged rid of it.

  • python mock side_effect or return_value dependent on call_count

    - by user18380
    To test a polling function I want to mock the calling of a sub function so that the first time it is called it will fail, and the second time it is called it will succeed. Here's a very simplified version of it: poll_function(var1): value = sub_function(var1) # First call will return None while not value: time.sleep(POLLING_INTERVAL) value = sub_function(var1) # A subsequent call will return a string, e.g "data" return value Is this possible to do with a Mock object from the mock framework? I know Mock objects have a call_count attribute I should be able to use somehow. Right now I've solved it by creating a custom mock object that I use to monkey patch sub_function(), but I feel there should be a better less verbose way of doing it: def test_poll(): class MyMock(object): def __init__(self, *args): self.call_count = 0 def sub_function(self, *args, **kwargs): if self.call_count > 1: return "data" else: self.call_count += 1 return None my_mock = MyMock() with patch('sub_function', my_mock.sub_function): ok_(poll_function())

  • Debugging compiled .NET 2.0 application

    - by brovar
    I don't know if I'll pass all the necessary information here, but I've only been asked to post this question here and I'm not entirely onto the matter. There is a .NET Framework 2.0 application compiled in the Debug mode with the parameter jitDebugging set to true in app.config <system.windows.forms jitDebugging="true" /> After any crash we get the dialog box allowing us to send a report or to debug the program. When we choose to debug and select proper VS, the IDE starts but with the announcement: No symbols are loaded for any call stack frame. The source code cannot be displayed. and Disassembly cannot be displayed in run mode. Is there any possiblity to see the code or the spot where the crash has occured?

  • Error 2908 when installing assemblies into GAC

    - by yfrolov
    Hi, I'm receiving 2908 (0x80131047: The given assembly name or code-base is invalid) error when running my MSI package. The problem occures when the MSI tries to deploy a component with .NET assembly into a GAC. NOTE: only assemblies with dependencies fail. The MSI is created with IS 2010. I am able to deploy the assembly manually with GACUTIL. I verified .NET Framework (all versions upto 3,5)is installed. I verified assembly properties are identical with MsiAssemblyName table properties. However, somehow I had made the installation working fine before. But when the product was moved to Visual Studio 2008 and .NET 3.0 I started facing the problem. Do you guys have any thought on this. Any ideas are appreciated. Thanks much!

  • Java REST Interface

    - by Vikram
    I have a PHP web application environment. I am using Slim Framework as REST interface for my application. My application front-end is written using Backbone.js and jQuery. There is a utility (.jar file) which when I use command line makes a remote call (I guess this is a Web Service) which returns me the data. how do I best incorporate this into my webapplication described on top? My application front end will have a Button that should make an AJAX call to the REST Interface and fetch the data as JSON. My approach: PHP-REST interface url is: /api/phprestapi.php exists Add a JAVA-REST interface at url: /api/javarestapi.java (Perhaps) to separate these two Existing Environment: LAMP Stack on Ubuntu How do I achieve this? What is the kind of effort involved? Thanks for your pointers

  • Can the below function be improve?(C#3.0)

    - by Newbie
    I have the below function public static List<DateTime> GetOnlyFridays(DateTime endDate, int weeks, bool isIncludeBaseDate) { //Get only the fridays from the date range List<DateTime> dtlist = new List<DateTime>(); List<DateTime> tempDtlist = (from dtFridays in GetDates(endDate, weeks) where dtFridays.DayOfWeek == DayOfWeek.Friday select dtFridays).ToList(); if (isIncludeBaseDate) { dtlist = tempDtlist.Skip(1).ToList(); dtlist.Add(endDate); } else { dtlist = tempDtlist; } return dtlist; } What basically I am doing is getting the datelist using the GetDates function and then depending on the isIncludeBaseDate bool value(if true) skipping the last date and adding the Base Date It is working fine but can this program can be improve? I am using C#3.0 and Framework 3.5 Thanks

  • Linking error in OMNeT++ using Boost serialization library

    - by astriffe
    I'm very new to OMNeT++ and I'd like to use the serialization-library contained in the boost framework. However, when trying to use it, I get quite many errors such as: Description Resource Path Location Type undefined reference to `boost::archive::archive_exception::~archive_exception()' OmCCN line 36, external location: /home/alexander/UniBE/BT/simulator/boost-compiledLibs /include/boost/serialization/throw_exception.hpp C/C++ Problem . I guess the problem is that I didn't yet link the compiled library in OMNeT. I've had a look at the makefile but any changes there are worthless since it is generated automatically by makemake. Furthermore, trying to access the menu item 'makemake' in project properties OMNeT++ IDE throws an error (The currently displayed page contains invalid values). Can anyone give me a hint concerning what the error could cause or how to link the compiled library correctly? Any hints are very appreciated! cheers alex

  • Object initialization sequence in Objective-C

    - by Alex
    Hello everyone. The Cocoa framework has a convention to always call self = [super init] in the init method of an inherited class, because [super init] may return a new instance. What will happen if I do this? @interface MyClass : NSObject /* or any other class */ { int ivar_; } @end @implementation MyClass - (id)init { ivar_ = 12345; if ((self = [super init])) { NSLog(@"ivar_'s value is %d", ivar_); } return self; } @end In the case when [super init] returns a new instance, what will I see in the console? ivar_'s value is 0? I can't think of a way to check this myself, because I don't know which class may return a new instance from its init method. Also, can't seem to find explicit clarification for this scenario in the docs. Could anyone help me out? Thanks!

  • How to add javascript to YII correctly?

    - by RD.
    I want to create several javascript function that will be needed on different pages. Most will be relevant only to one page, but some to several. I know if I add general conversion functions, it would be a good idea to just create a new javascript file and put all these generic functions into that one file. Bringing me to my first question: Where would you store the generic javascript file? In "protected"? Which subfolder? Then, I need to address the placement of other javascript code. If I have javascript that will only be used on one page, should I use this technique or should I stick to a similar approach as above? The emphasis is on doing it correctly. I want to fall exactly in line with the yii framework.

  • Problem installing wordpress child themes.

    - by Jay
    Hi, I've tried to install either the Fusion or Thematic child themes for my blog. My Wordpress directory is located at myblog/wordpress while my domain is just myblog (example). Everything works fine with both basic themes or the parent Fusion or Thematic themes. When I install a child theme for either framework, I can view the preview and select 'activate.' However, after that my entire site crashes. I can't even view the wordpress admin panel. I've had to restore my database from my hosting provider just to get my blog working. All that I'm able to see is my favicon icon and a blank page. I've tried to deactivate all plugins and this doesn't help either. I really want to use the Hybrid News child template. Any thoughts on what might be happening? thanks so much!

  • Quick to develop web app in Java

    - by Mike Q
    Hi all, I need to develop a basic web app very quickly (1 week) for a demo. My requirements are Java (I need to make use of existing Java libraries to access the relevant data) 2 screens One for static data view, maybe some search parameters Other for basic form entry No fancy AJAX required Ideally easy for a web designer to come in and tart it up as necessary, without having to rewrite everything My first stop was going to be to checkout Wicket as I've heard good things about it. I don't have the time right now to dive into anything heavy, which probably writes off JSF in my mind (I played with JSF1, steep learning curve which I've now slid back down). I'm happy to treat the result as throwaway so if there's a framework which starts of well but then doesn't scale up to bigger projects, that would be ok. Any suggestions appreciated on frameworks/approach.
