    - by msfanboy
    Hello, these are my 2 classes a Attachable Property SelectedItems: code is from here: http://stackoverflow.com/questions/1297643/sync-selecteditems-in-a-muliselect-listbox-with-a-collection-in-viewmodel The namespace TBM.Helper is for sure proper as it works for other classes too. The namespace reference is also in the xaml file: xmlns:Helper="clr_namespace:TBM.Helper" But <ListBox Helper:SelectedItems.Items="{Binding SelectedItems}" ... does not work because = The property 'SelectedItems.Items' does not exist in XML namespace 'clr_namespace:TBM.Helper'.

  • time series in python up to microseconds

    - by Abruzzo Forte e Gentile
    Hi All I would like to handle time series in python. I have been suggested to use scikit.timeseries but I need to handle up to microseconds and this last, as far as I know, handles up to milliseconds. Do you know any other library able to do that? At some point I need to merge 2 time series sampled at different time, and I would like to avoid rewriting such kind of features or any new classes from scratch whenever it is possible. I thank you all AFG

  • Why should GoTos be bad?

    - by lisn
    I'm using gotos and a lot of them. C++, PHP or COBOL - I use them on nearly all occasions where everybody else would use functions or even classes. Yet my code is Clear Maintainable Bug-free Fast So why does everybody I meet tell me about how bad gotos are? Are there any facts that show that they are "bad"?

  • UIHint can not resolve template in abstract models

    - by Reza Owliaei
    Assume an abstract model like this: public abstract class MyClass : BaseEntity { [UIHint("File")] public long? DocumentFileId { get; set; } } The problem is Cannot resolve template 'File', while there is File.cshtml in View editor templates. The point is, if I don't define MyClass as an abstract class, error will be solved. My question is, why editor template can not resolve in abstract classes, and how can I handle it?

  • Ruby Rails _without_ ActiveRecord

    - by devlearn
    Hello, I'm looking for any pointers on how to write a rails web app without ActiveRecord. A doc or an example of a (not too complex) web app using storage backends other than a relational database would be greatly appreciated. It's not clear on what should be implemented in the model classes in order to make the rails app work without the ActiveRecord layer. Thanks,

  • which should be drawn first , class or sequence diagram?

    - by m0j1
    hi , I've had this discussion with my professor at college about UML diagrams . hi believes that sequence diagrams should be drawn before getting to class diagrams . but I think the opposite . I think after finishing the usecase diagram , the next diagram should be class diagram and after that we should get to sequence diagram . Rational rose requires us to use the classes in sequence diagram, which are already in class diagram . can anyone help me with this? thanks

  • Which type of design pattern should be used to create an emulator?

    - by Facon
    I have programmed an emulator, but I have some doubts about how to organizate it properly, because, I see that it has some problems about classes connection (CPU <- Machine Board). For example: I/O ports, interruptions, communication between two or more CPU, etc. I need for the emulator to has the best performance and good understanding of the code. PD: Sorry for my bad English. EDITED: Asking for multiple patterns.

  • How to learn proper C++?

    - by Chris
    While reading a long series of really, really interesting threads, I've come to a realization: I don't think I really know C++. I know C, I know classes, I know inheritance, I know templates (& the STL) and I know exceptions. Not C++. To clarify, I've been writing "C++" for more than 5 years now. I know C, and I know that C and C++ share a common subset. What I've begun to realize, though, is that more times than not, I wind up treating C++ something vaguely like "C with classes," although I do practice RAII. I've never used Boost, and have only read up on TR1 and C++0x - I haven't used any of these features in practice. I don't use namespaces. I see a list of #defines, and I think - "Gracious, that's horrible! Very un-C++-like," only to go and mindlessly write class wrappers for the sake of it, and I wind up with large numbers (maybe a few per class) of static methods, and for some reason, that just doesn't seem right lately. The professional in me yells "just get the job done," the academic yells "you should write proper C++ when writing C++" and I feel like the point of balance is somewhere in between. I'd like to note that I don't want to program "pure" C++ just for the sake of it. I know several languages. I have a good feel for what "Pythonic" is. I know what clean and clear PHP is. Good C code I can read and write better than English. The issue is that I learned C by example, and picked up C++ as a "series of modifications" to C. And a lot of my early C++ work was creating class wrappers for C libraries. I feel like my own personal C-heavy background while learning C++ has sort of... clouded my acceptance of C++ in it's own right, as it's own language. Do the weathered C++ lags here have any advice for me? Good examples of clean, sharp C++ to learn from? What habits of C does my inner-C++ really need to break from? My goal here is not to go forth and trumpet "good" C++ paradigm from rooftops for the sake of it. C and C++ are two different languages, and I want to start treating them that way. How? Where to start? Thanks in advance! Cheers, -Chris
