  • Creating a C# DLL and using it from unmanaged C++

    - by John
    I have a native (unmanaged) C++ application (using wxWidgets for what it's worth). I'm considering a separate tool application to be written in C# which would contain winform-based dialogs. putting some of those dialogs in a separate DLL would be useful as I'd hope to be able to use them from my C++ app. But I have no idea how much messing about is needed to accomplish this, is it particularly easy?

  • Select the next N elements of an IEnumerable<T>

    - by sassafrass
    Say you've got some IEnumerable called S of length N. I would like to select all continuous subsequences of length n <= N from S. If S were, say, a string, this'd be pretty easy. There are (S.Length - n + 1) subsequences of length n. For example, "abcdefg" is length (7), so that means it has (5) substrings of length (3): "abc", "bcd", "cde", "def", "efg". But S could be any IEnumerable, so this route isn't open. How do I use extension methods to solve this?

  • Creating multiple objects of a view defined in the xml

    - by user362953
    I have to dynamically add a list of views (the views use RelativeLayout). Can I do this by specifying the view definition in xml and instantiate multiple objects off it? This gives the usual benefits of separating the view part from the code (for e.g., making it easy for the UI guys to alter things) or Is going the ArrayAdapter the suggested/only route?

  • I'm still learning OOP. Any tips on staying unbiased and pragmatic?

    - by marcdev
    I keep reading about defficiencies and issues with languages. Specifically, I'm learning PHP and Javascript, but I see it everywhere. This question arose while reading Javascript: The Good Parts and PHP Objects, Patterns and Practice. While understanding and avoiding easy pitfalls, is there a way I can learn the fundamentals of OOP and discover solid programming practices without overlooking important areas (or simply becoming jaded)? I'm sure I'll have plenty of opportunity to learn from mistakes!

    - by VaioIsBorn
    I know how to do it mathematically, but i want it now to do it in c++ using some easy algorithm. Is is possible? The question is that i need some methods/ideas for writing a number N in base M, for example 1410 in base 3: (14)10 = 2*(3^0) + 1*(3^1) + 1*(3^2) = (112)3 etc.

    - by Linda Cohen
    I want to define a function replicate to replicate a list of numbers by its value using only list comprehension, for example: replicate [5,1,3,2,8,1,2] output: [5,5,5,5,5,1,3,3,3,2,2,8,8,8,8,8,8,8,8,1,2,2] I know this would be easy to use the 'replicate' built in function but only list comprehension is allow, how can I do this?

  • Shortcut for moving between Vim windows

    - by Kamilski81
    Let's say I have single Vim tab displaying 9 buffers (equally separated, like a table 3x3). Currently, to get from the top left window to the bottom right one, I have to press 3, Ctrl+W, J, and then 3, Ctrl+W, L. This is cumbersome and I would like to just be able to press Ctrl+9 to go to the 9th window and Ctrl+3 to go to the 3rd window, etc. Is there any easy way I can map something like this in Vim?

  • Rails - single ID for multiple models

    - by user352351
    I'm building an app which will allow a user to scan the barcode on a 'shelf', 'box' or 'product' which will then bring up that particular item or all the associated items. As these are all separate models with their own ID's, I need a global ID table. I was thinking of a polymorphic table called 'barcodes' barcodes id barcode_number barcodable Is there an easy way to do this? Or is polymorphic the best way?

  • regular expression - function body extracting

    - by Altariste
    Hi, In Python script,for every method definition in some C++ code of the form: return_value ClassName::MethodName(args) {MehodBody} ,I need to extract three parts: the class name, the method name and the method body for further processing. Finding and extracting the ClassName and MethodName is easy, but is there any simple way to extract the body of the method? With all possible '{' and '}' inside it? Or are regexes unsuitable for such task?
