updates

问题 He I am noob to Java (Thats not new) and I can't find a good tutorial for this. I use jTable to display a table filled with data from a MySQL database. So far so good, I get the table: Standard you can click a table cell and it changes to a text-field with can be filled with something new. You all know that, but how can I use this to also update the value in my database? My code: import [...]; public class table extends JPanel { public String table; private Database db; public table(String

问题 Every once in a while, "IntelliJ IDEA is ready to update.". In these cases, it is sometimes required to uninstall the current version and to install the new version. When that happens, the installer asks whether to uninstall the previous version silently: "Uninstall silently (settings and configuration from old versions will not be deleted)". This to me is ambiguous. Does "uninstall silently" mean that a copy of my settings will be cluttering my file system, or does it mean that the settings

问题 I've searched a bit around the web and found a few ideas on how to do what I want, but I would still like to know what you think I should do. Here is the context : I'm developing an app for iOS 5. I use MapKit to display a map, and I add around 5000 annotations to it - yup, that seems a lot, but don't worry, I use a clustering library :). In order not to load them every time the user opens the map, I create them in my appDelegate (I create an array of annotations, and call [_mapView

问题 So I am in branch feature . And I want to rebase w/ branch master . git rebase master And it says that feature branch is up-to-date. Of course it is because master branch hasn't changed — it is the same as in moment when I create feature branch from it. Actually it is not. All I need is to do pull in master branch. git checkout master git pull git checkout feature My question: can't I update master branch w/o checking-out to it? I tried from feature branch: git pull origin master master ..

问题 I come from a Ruby on Rails API background, but am currently working on a .NET C# WebAPI. I am familiar with C# and .NET webforms. I'm attempting to set up a PUT request that will update a record in the db. The scaffolded method overwrites all the fields, whereas I want to simply update just the fields passed through the PUT. I attempted with the below code: // PUT: api/Users/5 [ResponseType(typeof(void))] public IHttpActionResult PutUser(string id, User user) { if (!ModelState.IsValid) {

问题 Everything was working fine in my Portable-Class-Library project until I updated all the installed portable libraries. It has stopped compiling. Throws the following errors for the nuget libraries installed. C:\Windows\Microsoft.NET\Framework\v4.0.30319\Microsoft.Common.targets(1605,5): warning MSB3268: The primary reference "System.Threading.Tasks" could not be resolved because it has an indirect dependency on the framework assembly "System.Runtime, Version=2.6.3.0, Culture=neutral,

问题 Is there an RSS/Atom feed or a mailing list for updates to Git that I can subscribe to? I find it hard to keep up-to-date with the latest version, as I have no way on knowing when a new version is released. 回答1: For msysgit (windows port), it's simply the feed provided by Google Code: http://code.google.com/feeds/p/msysgit/downloads/basic But since there's a central location for git related stuff (http://git-scm.com), the better thing would be to have the feeds provided from there. Maybe you

问题 My understanding is that Memcached is lockless (in its default configuration), such that no client can impede any other client's operation. If that is the case, then how does Memcached handle two or more clients attempting to update the same object at the same time? How does Memcached handle multiple versions of an object? Simply take the one whose update finished last and evict the other versions from the cache? Is the database actively invalidating objects cached on a Memcached server? 回答1:

问题 I'm using instance transforms to install the same product multiple times on the same machine. When starting the .msi installation file, I pass TRANSFORMS=":X" (and several other variables needed for the installation) on the command line, where X is the version of the Program to use. In the Product.wxs file I then assign a new ProductCode using the InstanceTransforms tag, e.g.: <Property Id="INSTANCEID" Value="Default"/> <InstanceTransforms Property="INSTANCEID"> <Instance Id="I1" ProductCode=

问题 Having used Rtools for a while on R v3.3.3 and 64bit Win10, I suddenly faced the following error when trying to locally install, i.e., compile_dll(pkg = "...", quiet = FALSE) or load_all(pkg = "...") any package via devtools : *** fatal error - cygheap base mismatch detected and the following suggestion in the error output: This problem is probably due to using incompatible versions of the cygwin DLL. Search for cygwin1.dll using the Windows Start->Find/Search facility and delete all but the
