  • Why do so many wpf controls implement CLR properties instead of dependency properties ?

    - by msfanboy
    Hello, is it because the controls programmers are lazy, too hard to implement or not knowledgeable? Wether they are custom controls from 3rd party vendors or Microsoft itself, very much controls have often clr properties instead of DP. Result is I can not bind to them and is wpf not all about binding? :/ My next side question would be, why do so many wpf controls offer visual parts but they are not member of the visual tree ? see wpf datagrid columns, headers... What do you think?

  • How to create an array of buttons in C++

    - by mangoman13
    Hi, I'm using C++ in VS2005 and have an 8x8 grid of buttons on a form. I want to have these buttons in an array, so when I click on any of them it will open the same event handler (I think that is what they are called), but I will know the index of which one was clicked on. I know how to do this in VB and C#, but I can't seem to figure it out with C++ Right now I have all my buttons labelled by their location, i.e. b00, b10, b21, etc. So I think what I am looking for is a way to do something like this: Button b[8][8]; //this causes me errors (error C2728: 'System::Windows::Forms::Button' : a native array cannot contain this managed type) and (error C2227: left of '->{ctor}' must point to class/struct/union/generic type) void Assignment(){ b[0][0] = b00; b[1][0] = b10; ... } and then in form1.h: private: System::Void b_Click(System::Object^ sender, System::EventArgs^ e) { //somehow read the coordinates into variables x and y //do something based on these values } Any help would be appreciated. Also let me know if I am going in the complete wrong direction with this. Thanks!

  • advanced winform framework

    - by alfredo dobrekk
    Hi, i m starting a new project that would basically take input from user and save them to database among about 30 screens, and i would like to find a framework that will allow the maximum number of these features out of the box : .net c#. windows form. unit testing continuous integration screens with lists, combo boxes, text boxes, add, delete, save, cancel that are easy to update when you add a property to your classes or a field to your database. auto completion on controls to help user find its way use of an orm like nhibernate easy multithreading and display of wait screens for user easy undo redo tabbed child windows search forms ability to grant access to some functionnalities according to user profiles mvp/mvvm or whatever design patterns either some code generation from database to c# classe or generation of database schema from c# classes some kind of database versioning / upgrade to easily update database when i release patches to application once in production code metrics analysis some code generator i can use against my entities that would generate some rough form i can rearrange after code documentation generator ... Any ideas ? I know its lot but i really would like to use existing code to build upon so i can focus on business rules. Do u have any suggestion to add to the list before starting ? What open source tools would u use to achieve these ?

  • How do I diff two spreadsheets?

    - by neu242
    We have a lot of spreadsheets (xls) in our subversion repository. These are usually edited with gnumeric or openoffice.org, and are mostly used to populate databases for unit testing with dbUnit. There are no easy ways of doing diffs on xls files that I know of, and this makes merging extremely tedious and error prone. I've found Spreadsheet Compare, but it requires Excel 2000 or later. I've also tried to convert the spreadsheets to xml and doing a regular diff, but it really feels as a last resort. Are there any tools for diffing two spreadsheets (xls or ods)? I am primarily looking for a multi-platform/open source tool.

  • What is the IoC / "Springy" way to handle MVP in GWT? (Hint, probably not the Spring Roo 1.1 way)

    - by Ehrann Mehdan
    This is the Spring Roo 1.1 way of doing a factory that returns a GWT Activity (Yes, Spring Framework) public Activity getActivity(ProxyPlace place) { switch (place.getOperation()) { case DETAILS: return new EmployeeDetailsActivity((EntityProxyId<EmployeeProxy>)place.getProxyId(), requests, placeController, ScaffoldApp.isMobile() ? EmployeeMobileDetailsView.instance() : EmployeeDetailsView.instance()); case EDIT: return makeEditActivity(place); case CREATE: return makeCreateActivity(); } throw new IllegalArgumentException("Unknown operation " + place.getOperation()); } It seems to me that we just went back hundred of years if we use a switch case with constants to make a factory. Now this is official auto generated Spring roo 1.1 with GWT / GAE integration, I kid you not I can only assume this is some executives empty announcements because this is definitly not Spring It seems VMWare and Google were too fast to get something out and didn't quite finish it, isn't it? Am I missing something or this is half baked and by far not the way Spring + GWT MVP should work? Do you have a better example of how Spring, GWT (2.1 MVP approach) and GAE should connect? I would hate to do all the plumbing of managing history and activities like this. (no annotations? IOC?) I also would hate to reinvent the wheel and write my own Spring enhancement just to find someone else did the same, or worse, find out that SpringSource and Google will release roo 1.2 soon and make it right

  • How to use Eclipse and versioning for a matrix of projects

    - by Nulldevice
    Our company develop several software products, which reuse each others packages (we use Java). Every product represented as separate Eclipse Java project and has it's own versioning repository (we use Mercurial). When we find a bug in some shared package, we need to transfer changes to all consuming projects, and this is a hell. The key problem is that Eclipse project can be associated only with one versioning repository. Could someone recommend some way to associate Eclipse Java project whith several versioning repositories which in ideal may be geterogeious (svn, git, mercurial) ?

  • Should commit messages be written in present or past tense?

    - by user68759
    So which is it that you think is better and more intuitive? Fixed the XXX bug in YYY Fix the XXX bug in YYY Fixes the XXX bug in YYY Fixing the XXX bug in YYY Please provide your rationales. Note I am asking from your general perspective, meaning you should not try to associate this with your preferred svn/cvs tools or programming languages, but rather think of it as something that should/can be applied to any tools and programming languages.

  • Is there a tool to build and test a local change on multiple platforms

    - by Ben
    A company I used to work for was plagued with build breakages. So they made a tool that would zip up a developers local changes (which it detected from SCM) and send them to a remote server for a test build. The remote server would update its copy of the source with the repository and then apply the changes it received from the developer. It would then build and test the changes. We actually targeted multiple platforms so it would do the above for each of those platforms. When it was done, if everything was green, the developer was reasonable confident they could submit the change without breaking the "real" build. Are there any tools out there that do something similar?

  • Managing important runtime business logic with regard to a codebase

    - by Daniel Beardsley
    I'm working on a project which will end up have a lot of application information stored in the form of records in a database. In this case, it's the configuration of data views: which grid columns to show/hide default filters to apply to each grid view column titles sorting subtotaling ... This information is a big part of the value of the application and is essential to it's function. The data will be altered by admins a fair amount, so it's not static and it wouldn't be appropriate to have to deploy a new version of the app every time the data changes. The question is, Where should this data be stored? It will definitely live in the database because that's how it's accessed, but I feel like it needs to also be kept with the version controlled codebase because it's an integral part of functioning of the application. Has anyone dealt with an issue like this before? What did you end up doing?

  • Git: What is a tracking branch?

    - by jerhinesmith
    Can someone explain a "tracking branch" as it applies to git? Here's the definition from git-scm.com: A 'tracking branch' in Git is a local branch that is connected to a remote branch. When you push and pull on that branch, it automatically pushes and pulls to the remote branch that it is connected with. Use this if you always pull from the same upstream branch into the new branch, and if you don't want to use "git pull" explicitly. Unfortunately, being new to git and coming from SVN, that definition makes absolutely no sense to me. I'm reading through "The Pragmatic Guide to Git" (great book, by the way), and they seem to suggest that tracking branches are a good thing and that after creating your first remote (origin, in this case), you should set up your master branch to be a tracking branch, but it unfortunately doesn't cover why a tracking branch is a good thing or what benefits you get by setting up your master branch to be a tracking branch of your origin repository. Can someone please enlighten me (in English)?

  • What performance overhead do IoC containers involve?

    - by Sosh
    Hi, Loose coupling is wonderful of course, but I have often wondered what overhead wiring up dynamically using an IoC container (for example Castle Windsor) has over a tightly coupled system? I know that a detailed answer would depend on what the IoC was being used for, but I'm really just trying to get a feel for the magnitude of effort involved in the IoC work. Does anyone have any stats or other resources regarding this? Thanks

  • Git/SVN for asp.net development instead of VSS?

    - by jrutter
    At work, we are using ASP.net 2.0 and VSS. VSS is a beast, we are continually having issues with people checking out files and there is no branching - makes it crazy. I know SVN/GIT is mainly used by open source developers, are there any downsides to ASP.NET developers using it? I have been pushing for SVN internally, but am thinking GIT might also be a great option. Our team is spread across 3 continents.

  • Is there any way to add references without recompiling in .NET?

    - by Jader Dias
    I am using a IoC Container (Castle Windsor) to instantiate classes accordingly to the configuration file. If I want to add classes from a new dll that didn't exist when I compiled the project, there is any way to do that without recompiling? Edit: As this project is a Service Host for WCF service, and the classes that I want to include after compilation are WCF Services I would like also to know if I can include endpoint information about new services without recompiling.

  • Android 2.1 address bar causes change in viewport dimensions

    - by davehumyo
    Hi, I have a page that has a 100% width and height div in it (all surrounding elements are sized accordingly so that it does actually achieve 100% width and height). Below that div I have a second div with a fixed height. In mobile safari and blackberry everything is fine, when the page loads the dimensions are applied correctly (the top div filling the viewport) and the user can scroll down to reveal the second div. Android 2.1 also applies the dimensions correctly, but with an added quirk; when the user scrolls down and removes the address bar from the page, the dimensions of the div are recalculated to fill the viewport, causing the content to jump. Ideally I would like the dimensions of the div to remain static when the page is scrolled, but remain 100% so that it will fill the viewport regardless of device size or orientation. Does anyone know of any way to disable this recalculation? Thanks for any help you can provide.
