version

Other than running it on a computer that only has .NET Framework Version 3.5, how do I check what version a .NET app is? .NET framework versioning went foobar after .NET 2.0. An app targets a CLR version, it does so with the assembly metadata for the EXE. And there are currently four of them, 1.0, 1.1, 2.0 and 4.0. Not counting special ones like used by the Compact Framework, Silverlight, Micro Framework. Framework versions 2.0, 2.0SP1, 2.0SP2, 3.0, 3.5 and 3.5SP1 all target the same CLR version, 2.0.50727. What's different between these releases is that they have additional assemblies

I want to know, at run time, whether I'm running on 32 bit or 64 bit windows. The OSVERSIONINFOEX structure tells me the major and minor version, but I'm guessing I need the build numbers. Anyone know what they are? If your application is compiled for 64-bit, then the answer's easy: you're running on 64-bit Windows. If your application is compiled for 32-bit, you need to call IsWow64Process . This function is only exported on Windows XP or later; if you want to support earlier versions of Windows, you'll need to use GetProcAddress to get a pointer to this function. Assuming you're using C++,

Question pretty much says it all. Is there an equivalent for org.hibernate.Version.getVersionString() in EclipseLink? Why isn't there a portable (JPA) way to query provider information in general? Never used it but from the Eclipselink javadoc you could try the following class: org.eclipse.persistence.Version There is a static class and static method to get this information. Example: How to print in java code AbstractSessionLog.getLog().log(SessionLog.INFO, DatabaseLogin.getVersion()); 来源： https://stackoverflow.com/questions/9617691/how-do-you-query-the-eclipselink-version-at-runtime-plus-jpa

After reading Michael Lopp's book "Being Geek," I started using Dropbox as a means of synchronizing files between my home computer and work computer. It's been fantastic, it really makes it painless to keep track of the latest version of files you're working on. My question has to do with people's experience with this tool, especially programmers who may have used it to develop larger projects. Right now, I see 3 main uses of Dropbox: 1. synchronize files between home and work computers 2. version control (you have to log into the dropbox site to access previous versions) 3. off-site backup

I've developed an iPhone application for an iOS Deployment Target 3.2. But my client changed his mind and would like the app to be available for iOS 3.1. Thus, i've set iOS Deployment Target 3.1 and left base SDK to 4.0 but everything compiles fine whereas I'm sure I use methods and classes introduced in iOS 3.2 only. How can I identify my code that won't run on a 3.1 device ? (and may cause an application crash) My problem is that I have a single iPhone device (with 4.0.2 installed) and that SDK 3.1.x are not provided by Xcode anymore. Henry, this might help you: install the old xcode & sdk

When I use an anonymous function ( but see also note below ) like : $f = function() use ($out) { echo $out; }; It produces an parse error on servers where PHP is older than 5.3.0 . My software needs to be compatible with unknown servers , but in the same time , I want also to use new functions, so I thought I will add some kind of a version check, if (o99_php_good() != true){ $f = function() use ($out) { echo $out; }; } where the o99_php_good() is simply function o99_php_good(){ // $ver= ( strnatcmp( phpversion(),'5.3.0' ) >= 0 )? true:false; $ver= ( version_compare(PHP_VERSION, '5.3.0') >= 0
