  • Covariance and contravariance real world example

    - by Sir Psycho
    I'm having a little trouble understaing how I would use covariance and contravariance in the real world. So far, the only example's I've seen have been the same old array example. object[] objectArray = new string[] { "string 1", "string 2" }; It would be nice to see an example that would allow me to use it during my development if I could see it being used elsewhere. Can anyone point me to some useful resources?

  • WordPress - moving from one host to another

    - by Maor
    I am trying to move a WordPress installation from one server to another one, including all of the SQL data, and the file-system data (photos,template files). I just have a problem changing the URLs in the database, since I need to replace the new URL with the old one. I would love to have some suggestions about how can I replace the URLs (maybe there's a rplace statement in SQL?) Thanks in advance.

  • Any addins for VS2010 to support VS2005 prjects?

    - by Eye of Hell
    Hello. Some of the old projects in our company are left to be built with VS2005 in autobuild system (making them built correctly in 2010 costs time). Is it any addins for VS2010 that will allow to open VS2005 project and edit it's files without converting project file itself to VS2010 format (converting will kill autobuild)? Of course i can create a separate project named "xxx_vs2010.vcproj" for each of such products, but that will be a mess :(.

  • Tuples vs. Anonymous Types vs. Expando object. (in regards to LINQ queries)

    - by punkouter
    I am a beginner who finally started understanding anonymous types. (see old post http://stackoverflow.com/questions/3010147/what-is-the-return-type-for-a-anonymous-linq-query-select-what-is-the-best-way-t) So in LINQ queries you form the type of return value you want within the linq query right? It seems the way to do this is anonymous type right? Can someone explain to me if and when I could use a Tuple/Expando object instead? They all seem very simliar?

    How can I get the rearranged columns out of a datagridview in C#? I need to get all the columns currently being displayed in order.

  • OpenGL: Implementing transformation matrix stack

    - by Jakub M.
    In a newer OpenGL there is no matrix stack. I am working on a simple display engine, and I am going to implement the transformation stack. What is a common strategy here? Should I build a push/pop stack, and use it with a tree representing my model? I suppose this is the "old" approach, that was deprecated in the newer OpenGL versions. Maybe then it is not the best solution (it was removed for some reason)

  • Eclipse project artefacts in Maven repository

    - by Georgios Gousios
    I want to use some of the libraries produced by the Eclipse project through Maven. I 've had a look at the main Maven repo and while it looks like that there are a few projects already imported, their versions are old and some important ones are missing (e.g. cdt). Is there any Eclipse project official Maven repository? If not, what would be the best option to use current versions of libraries such as the JDT compiler in a maven-enabled project?

    How can I force my objects DataContext bindings to update? I'm using an event on a grid, and binding updates are not being processed before my event fires. Any cheap tricks to get around this? In the end I can always do things the old manual way of getting the values from my textboxes and updating my object, but it'd be nice to have binding do it for me.

  • Is Spring.Threading.Helpers still supported?

    - by Paul Morrison
    I am converting some old C# code, and it has a CountDownLatch using a package called Spring.Threading.Helpers. The odd thing is that I can't find this package on Google - so a) is it still supported? And, if so, where is it documented? b) What I really want to do is wait for a count to get to zero, but interrupt every so many msecs. Would it just be simpler to set up another thread, and do WaitOnes on an Event specifying an interval? TIA

When I try to export a release build, I get this error: If I change the main-app.xml file to use the 1.5 version of the namespace, it builds fine. Unfortunately, the clients environment runs on 1.0. Ideas?
