copying

问题 I am using FileSystemWatcher to monitor a folder that will be used to do some file renaming. The only thing that will be copied will be folders containing files. There will not be single files put into the monitored folder. This is the code for setting up the FileSystemWatcher watcher.Path = path; watcher.NotifyFilter = NotifyFilters.DirectoryName | NotifyFilters.FileName; watcher.IncludeSubdirectories = true; watcher.Filter = "*.*"; watcher.Created += new FileSystemEventHandler(watcher

问题 I am using hadoop for processing the files, presently i am trying to copy the files from local file system to HDFS using the command below hadoop fs -put d:\hadoop\weblogs /so/data/weblogs Got the error as below c:\Hadoop\hadoop-1.1.0-SNAPSHOT>hadoop fs -put d:\hadoop\weblogs /so/data/weblog s 12/12/03 19:05:16 WARN hdfs.DFSClient: DataStreamer Exception: org.apache.hadoop .ipc.RemoteException: java.io.IOException: File /so/data/weblogs/weblogs/u_ex121 10418.log could only be replicated to 0

问题 I have a set of mask images that I need to use everytime I recognise a previously-known scene on my camera. All the mask images are in IplImage format. There will be instances where, for example, the camera has panned to a slightly different but nearby location. this means that if I do a template matching somewhere in the middle of the current scene, I will be able to recognise the scene with some amount of shift of the template in this scene. All I need to do is use those shifts to adjust

问题 I need to make a batch file that can copy files from one path to another based on parameters. For example, typing "datecopy -m 8 c:/copyfrom/*.* d:/copyto/*.*", would find all files in c:/copyfrom dated less than 8 months old, and copy them to d:/copyto -folder. Alternately, instead of -m for month, I could use -h for hour or -y for year. That's not the full program of course, but should get me started. Thanks for any potential tips. :) 回答1: I know this might not look like it's answering your

问题 I have two folders (say "A","B") which are in a folder (say "Input"). I want to copy "A" and "B" to another folder (say "Output"). Can I do this in R? 回答1: Copying your current directory files to their new directories currentfiles is a list of files you want to copy newlocation is the directory you're copying to If you aren't listing your current files, you'll need to loop through you're working directory file.copy(from=currentfiles, to=newlocation, overwrite = TRUE, recursive = FALSE, copy

问题 I have a method in my application which retrieves the last saved image in my DCIM/Camera folder and copies it to another location on the SD card. I've just tested it on another phone and found that it defaults saving to DCIM/100MEDIA . How am I able to get this path? I ended up writing some code which looped through all the folders in the DCIM folder and retrieved the path of the lastModified() folder. 回答1: Looks like it is manufacturer dependent. In addition to using methods described in

问题 Issue is what the title says. Earlier I used to copy text from text files open in vim simply by selecting text and doing Ctrl + C . But now it puts me into visual mode, thus not allowing to copy the text. Its really annoying. Anybody knows any fix for this. Thanks. 回答1: You probably have the mouse mode active. You can turn it off with: :set mouse= And turn it back on with :set mouse=a If you are using iTerm, you can leave mouse mode on all the time if you want, and hold Option when you want

问题 Does anyone know of a way to copy files with Paperclip using S3 for storage? Before I try to write my own, I just wanted to make sure there wasn't already a way to do this. Thanks 回答1: After some more messing around with paperclip, I figured it out. It's ridiculously simple to copy files! # Stupid example method that just copies a user's profile pic to another user. def copy_profile_picture(user_1, user_2) user_2.picture = user_1.picture user_2.save # Copied the picture and we're done! end
