问题 If I build a 1.0 app with 2 strings in the defaults, using registerDefaults . And in a 2.0 version, I decide to remove the first old string, and move the second one (changing its key string) with a new third one into an array. How may I deal with this and how to deal with the changes that could have been made to the content through versions. 1.0 Prefs should be StringKey someValue DateKey 10/10/2010 1.1 Prefs should be StringKey someValue DateKey 2010/10/10 2.0 Prefs should be Array Item0 is

问题 I have a wix installer that will install an XML file and then modify it. Installation works great. Today, I needed to add a couple of nodes to this XML file. So I modified the original file and then added some additional instructions to wix to assign these items values. Well, I get an error every time saying that it cannot find the node. I look and see what file it has in the directory and it still has the older file that did not have the node. How can I tell it to replace the XML file first

问题 I have a Windows server 2008 with SQL 2008 and TFS 2008 installed. And I have another box with SQL 2005 and TFS 2005 installed. Does anyone know of a way I can just transfer the databases (or data in another way) from TFS 2005 to TFS 2008. Any data on the 2008 box can be deleted. The machines are not in a domain so all accounts are local. So I'll have to fix that afterwards, but that's managable. Basically, can I attach the databases and run an upgrade command? 回答1: I'm pretty sure that this

问题 I want to store some data to a File (not database) on the Android device. Currently I'm using Context.getFileDir() as the parent directory. However, when you update the app that directory gets deleted. Is there a directory I can use from Context that won't get wacked when the user goes to update the application? Does it have to be the SD Card since that's not always generally available on all phones? 回答1: If you want to file not to be deleted on uninstall is not possible as you might know

问题 I've pretty big code base written on Django 1.5, it's about time to upgrade to the newest version (1.11.2) as many stuff don't work well.

问题 I want to update a Magento 1.4.2.0 to 1.6.x.y. instead of the latest version 1.7.x.y There are many articles on how to update a Magento installation to the latest version, but that´s not what I want. There are some forum threads where people are asking how to update to a specific version, but those all don´t sport a solution. It seems like it is only possible to unpack the tar.gz of the specific version, but it is not possible to use the command line tool, i.e. ./mage config-set preferred

问题 We are storing user preferences for a Java app in a JSON file using Jackson. As we continue to develop the app, we will be adding preferences, renaming preferences, and removing obsolete preferences. When the user upgrades the app to the next version the file format will likely have changed. This causes Jackson to throw an exception and the file can't be parsed even though the format is 90% the same. How should I handle upgrading the file format? I was thinking about using JSONT to upgrade
