  • Checking variable from a different class in C#

    - by Josh
    Greetings- I have 2 classes. One is called "Programs" and the other is called "Logs". The class called Programs has public const string m_sEnviron = ""; near the top and I need to check what the m_sEnviron variable is set to through my class called Logs. The variable m_sEnviron will get set from a scheduler called Tidal so how can I check its value from a different class. If this is not the best to do this then please let me know what the better ways are. Thanks in advance. Regards,

  • RegEx - Time Validation ((h)h:mm)

    - by Josh
    /^\d{1,2}[:][0-5][0-9]$/ is what I have. this limits minutes to 00-59. It does not, however, limit hours to between 0 and 12. For similarity and uniformity I would like to do this with RegEx alone if possible. Further-more I would like the first digit to be optional. i.e. 09:30 accepted as well as 9:30. I played around with ranges, but something out of range is always acceptable.

  • Binding TabControl ItemsSource to an ObservableCollection of ViewModels causes content to refresh on

    - by Brent
    I'm creating an WPF application using the MVVM framework, and I've adopted several features from Josh Smith's article on MVVM here... Most importantly, I'm binding a TabControl to an ObservableCollection of ViewModels. This means that am using a tabbed MDI interface that displays a UserControl as the content of a TabItem. The issue I'm seeing in my application is that when I have several tabs and I flip back and forth between tabs, the content is being refersh each time I change tabs. If you download Josh Smith's source code, you'll see that his app has the same problem. For example, click on the "View All Customers" button and scroll down to the bottom the ListView. Next click on the "Create New Customer" button. When you switch back to the All Customer view you'll notice that the ListView scrolls back to the top. If you switch back to the New Customer tab and place your cursor in one of the TextBoxes, then switch to All Customers tab and back, you'll notice that the cursor is now gone. I imagine that this is because I'm using an ObservableCollection, but I can't be sure. Is there any way to prevent the tab's content from refreshing when it receives the focus? EDIT: I found my problem when I ran the profiler on my application. I'm defining a DataTemplate for my ViewModels so it knows how to render the ViewModel when it is displayed in the tab... like so: <DataTemplate DataType="{x:Type vm:CustomerViewModel}"> <vw:CustomerView/> </DataTemplate> So whenever I switch to a different tab, it has to re-create the ViewModel again. I fixed it temporarily by changing my ObservableCollection of ViewModels to an ObservableCollection of UserControls. However, I would really still like to use DataTemplates if possible. Is there a way to make a DataTemplate work?

  • NSURL Connection will/won't load data

    - by jkap
    So here's my issue: I followed the NSURLConnection tutorial in the iPhone Developer Documentation almost to the T, and it only kinda works. Here's where it all goes wrong: The object seems to be created correctly and delegates to connectionDidFinishLoading, but with any URL I try to load the response data always ends up only being 0 bytes. I am running in the simulator if that makes any difference. Here's my relevant code: - (void)viewDidLoad { [super viewDidLoad]; self.title = @"WVFS Player"; //create a request NSURLRequest *theRequest = [NSURLRequest requestWithURL:[NSURL URLWithString:@"http://wvfs.josh-kaplan.com/nowPlaying.php"] cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:60.0]; // create a connection NSURLConnection *theConnection=[[NSURLConnection alloc] initWithRequest:theRequest delegate:self]; if(theConnection) { // create the datum responseData=[[NSMutableData data] retain]; } else { // code this later } } - (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response { [responseData setLength:0]; } - (void)connectionDidFinishLoading:(NSURLConnection *)connection { // make it work NSLog(@"Succeeded! Received %d bytes of data:",[responseData length]); // release it [connection release]; [responseData release]; } And here's my log output: [Session started at 2010-03-14 09:01:09 -0400.] 2010-03-14 09:01:14.784 WVFS[19571:207] Succeeded! Received 0 bytes of data: Any ideas? Thanks, Josh

  • How to implement menuitems that depend on current selection in WPF MVVM explorer-like application

    - by Doug
    I am new to WPF and MVVM, and I am working on an application utilizing both. The application is similar to windows explorer, so consider an app with a main window with menu (ShellViewModel), a tree control (TreeViewModel), and a list control (ListViewModel). I want to implement menu items such as Edit - Delete, which deletes the currently selected item (which may be in the tree or in the list). I am using Josh Smith's RelayCommand, and binding the menuitem to a DeleteItemCommand in the ShellViewModel is easy. It seems like implementing the DeleteItemCommand, however, requires some fairly tight coupling between the ShellViewModel and the two child view models (TreeViewModel and ListViewModel) to keep track of the focus/selection and direct the action to the proper child for implementation. That seems wrong to me, and makes me think I'm missing something. Writing a focus manager and/or selection manager to do the bookkeeping does not seem too hard, and could be done without coupling the classes together. The windowing system is already keeping track of which view has the focus, and it seems like I'd be duplicating code. What I'm not sure about is how I would route the command from the ShellViewModel down to either the ListViewModel or the TreeViewModel to do the actual work without making a mess of the code. Some day, the application will be extended to include more than two children, and I want the shell to be as ignorant of the children as possible to make that extension as painless as possible. Looking at some sample WPF/MVVM applications (Karl Shifflett's CipherText, Josh Smith's MVVM Demo, etc.), I haven't seen any code that does this (or I didn't understand it). Regardless of whether you think my approach is way off base or I'm just missing a small nuance, please share your thoughts and help me get back on track. Thanks!

  • Is it possible to group records belonging to an entity in dbunit?

    - by Joshua
    Our JPA entity model auto-generates primary key identifiers for user, user_address tables. Would it be possible to group these entities given below via dbunit, so that I don't need to provide neither the primary key as well as the foreign key reference from user_address.user_id. It is getting very hard to maintain these keys (i.e. I would prefer to group the primary record 'user' and the child records 'user_address' so that dbunit can group them automatically by looking up the entity metadata). Is it achievable? <user id="1" first_name="Josh" creation_date="2009-07-11 15:45:28"/> <user_address id="1" user_id="1" address="Main St" city="Los Angeles"/> I would prefer something like this <!-- First user --> <user first_name="Josh" creation_date="2009-07-11 15:45:28"/> <user_address address="Main St" city="Los Angeles"/> <!-- Second user --> <user first_name="Mary" creation_date="2009-07-11 15:45:28"/> <user_address address="Taylors St" city="San Jose"/>

  • Regex one-to-one mapping pattern replace

    - by polygenelubricants
    How would you use regex to write a function that replaces all lowercase letters with uppercase and vice versa? Note: this is NOT a homework question. See also my previous explorations of regex: Regex split into overlapping strings (Alan Moore's answer is especially instructive) Can you use zero-width matching regex in String split? (my solution exploits a known Java regex bug with regards to non-obvious length lookbehind!)

  • String searching algorithm for Chinese characters.

    - by Jack Low
    There are Python code available for existing algorithms for normal string searching e.g. Boyer-Moore Algorithm. I am looking to use this on Chinese characters and it doesn't seem like the same implementation would work. What would I go about doing in order to make the algorithm work on Chinese characters? I am referring to this: http://en.literateprograms.org/Boyer-Moore_string_search_algorithm_(Python)#References

  • Libboost 1.38.0 on Ubuntu 11.04 Natty

    - by scjosh
    I have a Linux/Ubuntu DLL that depends on libboost_thread-mt.so.1.38.0 (As shown in the picture below). I've tried various ways including building my own version of LibBoost 1.38.0 yet none of my methods have worked. I was wondering if 1.38.0 is available precompiled on earlier versions of Ubuntu or if my architecture (64 Bit) is not compatible with LibBoost. Any pointers on how to fix this error are greatly appreciated. http://joshua-ferrara.com/imgoid/images/1332518188.png Best Regards, Josh

  • Java serait un "Roi légèrement enrhumé", un cadre de Google appelle Oracle à le remettre d'aplomb

    Java serait un "Roi légèrement enrhumé" Pour un cadre de Google qui appelle Oracle à le remettre d'aplomb Josh Blosh, "Chief Java Architect" chez Google, vient de participer au Red Hat Middleware 2020. Lors d'une intervention particulièrement remarquée, il a regretté que la plate-forme Java soit « restée sans maître à bord (rudderless) depuis plusieurs années ». D'après lui, un malaise durable se serait même emparé de la communauté. La principale explication tiendrait au fait que « les disputes techniques et liées aux licences », particulièrement préjudiciables, ont « sapé l'énergie de la communauté et provoqué beaucoup de mauvaise presse »

  • What's the best platform for blogging about coding ?

    - by timday
    I'm toying with starting an occasional blog for posting odd bits of coding related stuff (mainly C++, probably). Are there any platforms which can be recommended as providing exceptionally good support (e.g syntax highlighting) for posting snippets of code ? (Or any to avoid because posting mono-spaced font blocks of text is a pain). Outcome: I accepted Josh K's answer because what I actually ended up doing was realizing I was more interested in articles than a blog style, getting back into LaTeX (after almost 20 years away from it), using the "listings" package for code, and pushing the HTML/PDF results to my ISP's static-hosting pages. (HTML generated using tex4ht). Kudos to the answers mentioning Wordpress, Tumblr and Jekyll; I spent some time looking into all of them.

  • Parallelism in .NET – Introduction

    - by Reed
    Parallel programming is something that every professional developer should understand, but is rarely discussed or taught in detail in a formal manner.  Software users are no longer content with applications that lock up the user interface regularly, or take large amounts of time to process data unnecessarily.  Modern development requires the use of parallelism.  There is no longer any excuses for us as developers. Learning to write parallel software is challenging.  It requires more than reading that one chapter on parallelism in our programming language book of choice… Today’s systems are no longer getting faster with each generation; in many cases, newer computers are actually slower than previous generation systems.  Modern hardware is shifting towards conservation of power, with processing scalability coming from having multiple computer cores, not faster and faster CPUs.  Our CPU frequencies no longer double on a regular basis, but Moore’s Law is still holding strong.  Now, however, instead of scaling transistors in order to make processors faster, hardware manufacturers are scaling the transistors in order to add more discrete hardware processing threads to the system. This changes how we should think about software.  In order to take advantage of modern systems, we need to redesign and rewrite our algorithms to work in parallel.  As with any design domain, it helps tremendously to have a common language, as well as a common set of patterns and tools. For .NET developers, this is an exciting time for parallel programming.  Version 4 of the .NET Framework is adding the Task Parallel Library.  This has been back-ported to .NET 3.5sp1 as part of the Reactive Extensions for .NET, and is available for use today in both .NET 3.5 and .NET 4.0 beta. In order to fully utilize the Task Parallel Library and parallelism, both in .NET 4 and previous versions, we need to understand the proper terminology.  For this series, I will provide an introduction to some of the basic concepts in parallelism, and relate them to the tools available in .NET.

  • Leaving Microsoft

    - by Stephen Walther
    After two and a half years working with the ASP.NET team, I’ve decided that this is the right time to leave Microsoft and, with the help of some friends, re-launch my ASP.NET training and consulting company. The company has the modest name Superexpert. While working on my Ph.D. at MIT, I was surrounded by professors and students who were passionate about knowledge. During the Internet boom, I was lucky enough to work side-by-side with some very smart and hard-working people to create several successful startups. However, the people I worked with at Microsoft were among the smartest and hardest working. Microsoft hires a small number of people and gives them huge responsibilities. It continues to amaze me that so few people work on the ASP.NET team when you consider how much the team produces. I had the opportunity to work with a number of inspiring people at Microsoft. I’ll miss working with Scott Hunter, Dave Reed, Boris Moore, Eilon Lipton, Scott Guthrie, James Senior, Jim Wang, Phil Haack, Damian Edwards, Vishal Joshi, Mike Pope, Jon Young, Dmitry Robsman, Simon Calvert, Stefan Schackow, and many others. I’m proud of what we accomplished while I was working at Microsoft. We reached out to the jQuery team and changed direction from Microsoft Ajax to jQuery. We successfully contributed several important new features to the open-source jQuery project including jQuery Templates, jQuery Data-Linking, jQuery Globalization, and (as John Resig announced at the last jQuery conference) jQuery Require. I’m looking forward to returning to training and consulting. We want to focus on providing consulting on the “right way” of building ASP.NET websites, which we call Modern ASP.NET applications. By Modern ASP.NET applications, I mean applications built with ASP.NET MVC, jQuery, HTML5, and Visual Studio ALM. Additionally, we want to help companies that have existing ASP.NET Web Forms applications migrate to ASP.NET MVC. If you are interested in having us provide training for your company or you need help building a custom ASP.NET application then please contact us at [email protected] or visit our website at Superexpert.com.
