copy

问题 I have a file that is being generated automatically on a server in a Windows domain, say, called, "prod" and I will need to have VB.NET to transmit this file to another server in another Windows domain, say, "QA", where QA and Prod have different credentials altogether and I have to authenticate that credential every time I opened up the destination folder. Therefore, I guess the regular filecopy method would not work, is there another way where we can accomplish this? Thanks a lot! 回答1: How

问题 I'm really wondering what this code does: scala> import java.nio.file._ import java.nio.file._ scala> Files.copy(Paths.get(""), Paths.get("")) res0: java.nio.file.Path = Shouldn't that throw a NoSuchFileException ? Reading the JavaDoc reveals: By default, the copy fails if the target file already exists or is a symbolic link, except if the source and target are the same file, in which case the method completes without copying the file. But I'm not sure this is the true cause, because Files

问题 I'm trying to export data from Green-plum to a text file(client) with pipe delimiter using PSQL and \copy. In the output i see single slash is converted to double slash and tab is converted \t. Example N\A is converted to N\\A So how to get just N\A instead N\\A and just spaces instead of \t ? Note: i`m allowed to use only \copy. Since my file is huge im getting space issue while use SED or Perl for find and replace 回答1: Assuming you don't have any "^" characters, you could use that as the

问题 in OpenCV, I have a matrix like this: [3 4 2; 5 2 1; 6 7 9], that is with 3x3 size. Now I want to change it into 3x1 size, and be like this: [3 4 2 5 2 1 6 7 9]. But this is not exactly what I want, my actual goal is to put zero before and after each value, at the same time repeat each value three times. So my goal matrix should be like this: [ 0 3 3 3 0 0 4 4 4 0 0 2 2 2 0 0 5 5 5 0 0 2 2 2 0 0 1 1 1 0 0 6 6 6 0 0 7 7 7 0 0 9 9 9 0 ]. I wrote the following code for this: for ( int i = 0; i <

问题 Is it possible to override the captions in the "Copy" menu when the iphone user long-presses on some text? Essentially, I'd like to change the text to something like "Create a Note" instead of "Copy". Is that possible? 回答1: You can add custom menus via UIMenuController's menuItems property, something like: UIMenuItem* item1 = [[UIMenuItem alloc] initWithTitle:@"One" action:@selector(DoThingOne:)]; UIMenuItem* item2 = [[UIMenuItem alloc] initWithTitle:@"Two" action:@selector(DoThingTwo:)];

问题 So I was reading an article to clone an object and array. All of them mentioned that Object.assign() can be used to copy an object but no one mentioned that Object.assign() will also work to shallow copy an array. Could anybody explain how it works? Code to Explain is in JS Bin : https://jsbin.com/kaqocixize/edit?js,console 回答1: JS is prototype-oriented language. That means that every construct in JS is in reality - an object! :) Objects differ in some metadata, e.g. specific properties.

问题 I currently have this code which will take files from a folder, open each one, print its name into the first column of my "Master file" close it and loop through the entire folder that way. In each file that is opened, there is information in cell J1 that I would like to copy and paste into column 3 of my "master file". The code works but will only paste the desired info from J1 into C2 over and over so the information keeps being written over. I need to increment down the list so the info

问题 This is the script I found via google. And I've edited the file name. Here it is : <html> <head>File copy in progress...Don't close this page.</head> <script type="text/javascript"> // initialize ActiveXObject and create an object of Scripting.FileSystemObject. var fso = new ActiveXObject("Scripting.FileSystemObject"); // copies a file to another location + overwrites the file if already exits fso.CopyFile("file1.txt", "file2.txt", 1); fso = null; </script> </html> But it is not copying
