问题 This question is a sequel of this question We're creating a dll, written in C++, providing access to some hardware. This dll implements and is accessed using COM interfaces. We also have a C# program that uses this dll through the COM objects. We're having an issue with the versions. Indeed, when running the C# program, it absolutely wants to use the exact COM/C++ dll version it used when compiling. I.e. if the C# program was compiled using COM/C++ dll 1.2.3.4, then the program will refuse to

问题 I know that there are managed shell extensions loaded by explorer.exe on a computer. I want to know what version of the CLR is loaded into explorer.exe. If I am running Vista or Win7, I can use Process Explorer and look at the .NET Assemblies tab of the properties for explorer.exe. However, this doesn't work on XP. Is there a way to get this info on XP? 回答1: Doesn't Process Explorer also show the the DLLs that have been loaded? Look for mscorwks.dll in that list, and see where it's being

问题 I'm working with an old (2.6.33.2) version of embedded Linux and have been asked to change the kernel so that differently patched kernel images can be told apart. At the moment, uname -v outputs e.g. "#1 Wed Sep 11 07:07:51 BST 2013 . Hence I'd like to change this so that any subsequent patches change the #1 part to a revision number defined as part of the patch (and to change the date part to be the date of the latest kernel patch), but I can't see where in the kernel this is set up. What

问题 I saw this question asked multiple times, however without satisfying answer: let's presume you have maven project producing some jar (java desktop app). How can one define version number in pom.xml, which would be automatically incremented (or even manually, does not matter) when appropriate (e.g. with every build) but with the possibility to load this version into the application? The goal is to display for the user the version of the app he is currently using. 回答1: There are in particular

问题 I have an app that works on Android 2.3.6, but will cause disruptions if deployed on 2.3.3. I will obviously implement some mechanism to stop it from working on such devices, but is there a way to mark an app compatible with 2.3.6 but incompatible with 2.3.3, so the play store and possibly package installer would detect the incompatibilty? (Both versions are API level 10, otherwise this would be easy.) 回答1: check (String androidOS = Build.VERSION.RELEASE) while starting , then close or take

问题 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.
