问题 I am wondering, how would one write a file (say for instance, from a Console Application in a scheduled task) to another computer on a different domain? How would one set the Username and Password, such as with the "Log on to..." dialog to authenticate? Couple of prerequisites exist, obviously: The machines can see each other across the domains, however they need to authenticate You know the login details The username you would log in with has the appropriate permissions to write Anyone have

问题 I have a setup in which I make use of a txt file (both reading and writing to it) in my program. At present I have it setup such that I use the local filepath on my machine, however I need to package it up into an executable JAR. To do this I've tried switching the filepath string over to the following: String filepath = MyClass.class.getResource("/resources/textfile.txt"); However, when I run this I get a bunch of errors. After googling the method I found the similar method

问题 The facts: When a file is moved, there's two possibilities: The source and destination file are on the same partition and only the file system index is updated The source and destination are on two different file system and the file need to be moved byte per byte. (aka copy on move) The question: How can I determine if a file will be either logically or physically moved ? I'm transferring large files (700+ megs) and would adopt a different behaviors for each situation. Edit: I've already
