问题 How can I access the windows registry inside R. For example, I want to access the folder: [HKEY_LOCAL_MACHINE\SOFTWARE\R-core\R\3.0.2] and the key called "InstallPath" to get: "C:\\Program Files\\R\\R-3.0.2" Many thanks! 回答1: You could use readRegistry() . On my machine: fp <- file.path("SOFTWARE", "R-core", "R", "3.1.0", fsep="\\") readRegistry(fp, "HLM") ## "HLM" eventually resolves to "HKEY_LOCAL_MACHINE" # $InstallPath # [1] "C:\\R\\R-current" (Also, for future reference, in this case you

问题 I need a way to track the mouse coordinates more precisely than this code. If you run this code and move your mouse really fast or change directions fast, the coordinates might look this: 50 and then 40. It seems that when the mouse moves fast it doesn't track all the points the pointer covers, like in this example there are 10 coordinates that it skips. If I move it slowly, there's no problem. I need a way to track all the pointer coordinates with no skips. I've tried the sample on Code

问题 I have a problem where after my InstallShield project is built and I test the install on a clean 64bit Windows 7 machine, it creates a Wow6432Node key within a Wow6432Node key when I check regedit at HKEY_LOCAL_MACHINE\SOFTWARE. Everything registers correctly and the program seems to run fine. I have made sure that my project is the one that is causing this. I don't want to leave it as it is since it would be silly to have the registry like that. Does anyone know what might have caused this

问题 I've seen different kind of problems around, but I'm fighting with this for a whole day, so please give me some help :) Short story : I have different PATH variable in System Variables panel and cmd. Can't run exe files? Longer story : I'm trying to install Ruby. Tried with different versions, but the problem is the same: I have my PATH value updated, Ruby is there. BUT when using it from cmd, ruby is not recognized. echo %PATH% gives different value from the one in Environment Variables

问题 I've seen numerous ways of retrieving installed programs on WinXP+ in python. What is the proper and most robust way of doing this? Currently I'm accessing HKLM\\SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Uninstall and reading each of the keys from there to get a list. (I've been told this isn't the proper way of doing things) I've seen examples of using WMI/Win32com to do this as well but have seen comments along with those implementations that WMI might be turned off on certain machines
