auto-update

问题 I've got a small website that has about 5-10 administrators. I've set it up to monitor what each administrator is doing (adding items, removing items, etc). I had a list within our admin-panel that shows the previous 10 activities performed by the collective administration. Today, I decided to make this self-updating every 30 seconds. My question is simple: is there any problem doing this? I'm calling a small bit of text with each request, and the request is likely only running on 3 or 4

问题 I have searched through google and SO for possible answers to this question, but can only find small bits of information scattered around the place, most of which appear to be personal opinion. I'm aware that this question could be considered subjective, but I'm not looking for personal opinion, rather facts with reasons (e.g. past experience) or even a single link to a blog/wiki which describes best practices for this (this is what I'd prefer to be honest). What I'm not looking for is how to

问题 I have recently been setting up SVN in Eclipse using the Subversive plugin (I am still a bit lost, but that's another issue). I have been using this guide (http://soledadpenades.com/2008/12/10/add-svn-support-to-your-eclipse-installation/) and finally got it working! The only problem now is, I can't seem to find the Package Explorer, which is the only explorer I could ever seem to get working how I wanted it to (grouping projects into working sets). Normally, you get it from going to Window →

问题 What I'd like to do is create a "launcher" framework for my code that, given a URL and a predefined versioning scheme: 1) go check if an update exists 2) download the updates 3) "install" the update 4) "re-run" the application I want to a) do all of this inside of the existing JVM and b) be platform independent. Tall order right? Based on my (limited) knowledge of OSGi and Apache Felix I'm pretty sure this is possible, but I'm really getting lost in the details. Checking for an update and

问题 What is the best way to update an MSI installation over the internet? ClickOnce doesn't support MSIs. I need the update to occur automatically over the internet, in the same manner as Windows updates occur. Ideally, I would want my application to automatically detect that an update is available and download it and install it. Answers should only deal with MSIs installations. I don't mind if there needs to be a Windows Service installed to monitor for updates. 回答1: Here's what I've done for a

问题 I am searching for alternatives to autoupdating our software. Not ClickOnce and nor in the line of wyBuild and wyUpdate. 回答1: Try these: AutoUpdate+ [This one seems to have disappeared] IncUpdate Advanced Installer Updater Sharp AutoUpdater AutoUpdate AutoUpdater.NET NetSparkle WyBuild [Included here for completeness--though OP wanted alternatives] I use IncUpdate. It doesn't seem to be being updated anymore--but it continues to meet my needs (I released an update with it today). 回答2: I know

问题 I was using the timestamp trick on the Silverlight <object> (see GetLastWriteTime() using answers in How do you force Firefox to not cache or re-download a Silverlight XAP file?) successfully with Silverlight 4. Using a Silverlight 5 runtime * , the OOB install/auto-update feature now seems broken. I have two issues: when launching in browser, the current install state is always 'not installed' (in code: Application.Current.InstallState == System.Windows.InstallState.NotInstalled is always

问题 When creating an auto updating feature for a .NET WinForms application, how does it update the DLLs and not affect the currently running application? Since the application is running during the update process, won't there be a lock on the DLLs (because those DLLs will have to be overwritten during the update). 回答1: Usually you would download the new files into a separate area. Then shutdown and restart and at startup you look for and use the new files if found. Always keeping a last known

问题 I have multiple places where I convert between one coordinate system and another. In each case there is a cosine/sine calculation between, let's call them x, y and x', y'. These are all JFormattedTextFields. If the user enters a value in any of the 4, an ActionListener is called. Lets call the fields fieldx, fieldy, fieldx1, and fieldy1. If the user enters anything in fieldx or fieldy, I HAD keyboard and focus listeners (the same one for all four fields) that would update fieldx1 and fieldy1

问题 I have a Windows program that needs to update itself from a server automatically. It is already able to transfer files from the server and update + validate things like DLL plugin files before loading them. However, this program also needs to update itself. There are probably a few different ways this could be done, and the most obvious one I've seen from various online game clients is creating an "auto patcher" that downloads and then runs the client executable. That introduces the problem
