  • WPF 4, ListView and ListCollectionView custom sorting

    - by JustABill
    I'm trying to use a custom sort with a ListView, as described in this blog entry. I'm doing ListCollectionView view = (ListCollectionView)CollectionViewSource.GetDefaultView(TheList.ItemsSource); as recommended there and in several other places, but for some reason I'm getting "Unable to cast object of type 'MS.Internal.Data.EnumerableCollectionView' to type 'System.Windows.Data.ListCollectionView'." (TheList is of type ListView). What could be causing this?

    - by kasene
    Thread Title - Gathering Staff Rush-Soft Game Design is currently looking for staff of a moderate skill level. Team Name - RushSoft Game Design Project Name - N/A We are gathering staff so that we can begin working on a new game. Target Aim - Freeware / Free Version - Paid Version With our first project our aim is to simply get our name out there. Generally we will be targeting a freeware distribution platform or a Free and Paid version. Compensation - Prehaps in the future but don't rely on it If in the future we start developing a game we intend to make any sort of sizable profit from then yes, there will be compensation however currently our low, low funding comes from generous donations. Any money that we make for now will go to the teams funding for things like engine licenses and company registration. Technology - C/C++ RSETech Our primary functional language will be C/C++ as most games are. We will be using a custom built library built on Direct3D called RSETech or RushSoft Engine Technology. Currently its is fully capable of being used for developing a game. The final version is made up of almost entirely C (No C++ or OOP). There is a C++ version currently in the works. Programming: - Microsoft Visual C++ 2008 / 2010 2D Art - Photoshop CS2 - GIMP Talent Needed - We currently are in need of x2 Programmers - With understanding of the following C/C ++ and game programming aspects: -If/Else Conditions -Functions/Methods -Arrays -Pointers (You don't need to fully understand these. Just know when they need to be used.) -Enums -Loops (For and While) -Structs (and How to use . and - syntax) -Classes (and how to call methods and access variables from a class) -State Machines -Switches -Include Guards -Understanding of how game loops work in general. (Init, Update, Render, Deinit) x2 Artists - As long as you have the means to and are able to draw 2D sprites and collab with a game designer to get a good result. 1 or more Game Designers - You can design levels (for platformers) as well as write game scripts and you can come up with good ideas and game mechanics. As long as you can do these things and are able to work well with artists and programmers you're golden. Business Consultant - Someone who knows the industry and how it works. Will inquire about possible distribution platforms as well as contact other developers, websites, and publishers on RushSofts behalf.

  • Difficulties getting GraphViz working as a library in C++

    - by DistortedLojik
    Am working on a program that will allow a graph of nodes to be displayed and then updated visually as the nodes themselves are updated. I am fairly new to Visual Studio 2010 and am following the GraphViz guide located at http://www.graphviz.org/pdf/libguide.pdf in order to get GraphViz working as a library. I have the following code which is taken straight from the pdf linked above. #include <graphviz\gvc.h> #include <graphviz\cdt.h> #include <graphviz\graph.h> #include <graphviz\pathplan.h> using namespace std; int main(int argc, char **argv) { Agraph_t *g; Agnode_t *n, *m; Agedge_t *e; Agsym_t *a; GVC_t *gvc; /* set up a graphviz context */ gvc = gvContext(); /* parse command line args - minimally argv[0] sets layout engine */ gvParseArgs(gvc, argc, argv); /* Create a simple digraph */ g = agopen("g", AGDIGRAPH); n = agnode(g, "n"); m = agnode(g, "m"); e = agedge(g, n, m); /* Set an attribute - in this case one that affects the visible rendering */ agsafeset(n, "color", "red", ""); /* Compute a layout using layout engine from command line args */ gvLayoutJobs(gvc, g); /* Write the graph according to -T and -o options */ gvRenderJobs(gvc, g); /* Free layout data */ gvFreeLayout(gvc, g); /* Free graph structures */ agclose(g); /* close output file, free context, and return number of errors */ return (gvFreeContext(gvc)); } After compiling I get the following errors which indicate that I do not have it correctly linked. 1>main.obj : error LNK2019: unresolved external symbol _gvFreeContext referenced in function _main 1>main.obj : error LNK2019: unresolved external symbol _agclose referenced in function _main 1>main.obj : error LNK2019: unresolved external symbol _gvFreeLayout referenced in function _main 1>main.obj : error LNK2019: unresolved external symbol _gvRenderJobs referenced in function _main 1>main.obj : error LNK2019: unresolved external symbol _gvLayoutJobs referenced in function _main 1>main.obj : error LNK2019: unresolved external symbol _agsafeset referenced in function _main 1>main.obj : error LNK2019: unresolved external symbol _agedge referenced in function _main 1>main.obj : error LNK2019: unresolved external symbol _agnode referenced in function _main 1>main.obj : error LNK2019: unresolved external symbol _agopen referenced in function _main 1>main.obj : error LNK2019: unresolved external symbol _gvParseArgs referenced in function _main 1>main.obj : error LNK2019: unresolved external symbol _gvContext referenced in function _main Within the VC++ Directories I have C:\Program Files (x86)\Graphviz2.26.3\include in the Include Directories and C:\Program Files (x86)\Graphviz2.26.3\lib\release\lib in the Library Directories Any help would be greatly appreciated to help get this working. Thank you.

  • object array mobile development

    - by mixm
    Im currently creating a tile-based game for android. Using java via dalvik JVM. im fretting over a decision to represent objects in a particular map. should i use an id based map (2 dimensional integer array) and place game logic in a separate function in the game engine, or create an object array (2 dimensional array of game objects) and store game logic within the class methods. i am thinking about the cost of object creation and garbage collection vs extensibility.

  • Pintura OR Perserve 2.0 - Production Ready?

    - by Scott
    I'm very interested in this framework, coupled with a NoSQL backend like MongoDB. Basically, my blue-sky vision is this: ExtJS/Pintura/MongoDB. I would probably plug in Rhino as the js engine. Is there anybody here using Pintura in a production environment? What are the pitfalls? What is your general experience? Thanks.

  • Flash10 Triangle Rendering

    - by anon
    I know about Papervision 3D. However, alot of the realism there comes from textures. Does anyone know of a benchmark that shows how many single-color, flash-shaded 3D triagnels flash10 can reasonably render? I can't find this benchmark online or an engine for this (most seems to really value bitmaps / texture). Thanks!

  • Why doesn't nHibernate support LIMIT when doing "join fetch"?

    - by HeavyWave
    In nHibernate, if you do an HQL query with "join fetch" to eagerly load a child collection, nHibernate will ignore SetMaxResults and SetFirstResult and try to retrieve every single item from the database. Why? This behavior is specific to HQL, as ICriteria supports eager loading (with an outer join, though) and LIMIT. There are more details here http://www.lesnikowski.com/blog/index.php/nhibernate-ignores-setmaxresults-in-sql/ .

  • ColdFusion MVC frameworks & RESTful Service mismatch?

    - by Henry
    Most CF MVC Frameworks use the front controller pattern. Usually Search Engine Safe (SES) plugin together with URL Rewrite are used to construct friendly URLs. However, when it comes to implementing RESTful services, using a MVC framework seems like a layer of complexity added on top of another layer of complexity. How should one tame this beast? Any nice and clean approach of supporting RESTful services with ColdFusion? Any MVC framework out there that can expose RESTful services easily? Thanks

    - by Moshe
    I'd like to use Festival in an iPhone app. Is this possible, considering the way Festival generates and then plays back audio files? Can I pass Festival an audio file directly from itself to play back? or is there a different way to read things? Is there another Text-to-speech engine for C/C++ to use with iphone?

    - by BritishDeveloper
    When putting code samples in my blog I would like the code to have all the appropriate colours. How can I do that? Basically if I write: foreach (ListItem item in items) { item.Text = "something"; } I want it to appear in the correct colours like it does in my Visual Studio or here at stack*overflow*. I'm bored of styling the colours of each key word manually. Is there a pre-existing javascript library I can use?

  • A question about John Resig's Simple Javascript Inheritance.

    - by Zippo
    I'm using this simple code: http://ejohn.org/blog/simple-javascript-inheritance/ Using this "library", I made this simple class: var Person = Class.extend({ init: function(openningSentence) { this.say(openningSentence); }, say: function(words) { alert(words); } }); The problem with this class, is that I can't call a function using the variable "this" (line 3 in the code gives an error: unknown method "say"). Does anybody knoes if there's a solution for this problem? Btw - I'm using jquery, so if there's a jquery-based solution It'll be great :)

  • Typo blogging platform with Heroku hosting: theming

    - by Jack
    Does anyone know how to workarounds Heroku's limitations on writing to the theme files for the Typo blogging platform? I'd like to take advantage of the theming capabilities right from the browser. If any theme's stylesheet is changed I get the error message "Unable to write file" in addition to the fact that any theme being changed to one that is not the default causes the page to lose all styling and is displayed in plain text. I followed this (awesome) blog entry to get it up and working.
