copy

问题 ok so i'm trying to copy file.xml into another location something like copy('file.xml',../../folder/newfile.xml) ; it works just fine on my wamp virtual server but on my real site it doesn't. i thought that is something related to chmod and i changed the file.xml to 0777(with a ftp client). is there something that i should put in my code to make it right? or what? 回答1: Copy is a pretty straigtforward function. As Mark said, it's perhaps a host issue. 回答2: It might be that you don't have

问题 I'm currently writing a little paint application where the user is able to draw on a Panel. I am working on the select tool and want to be able to select a certain area of the Panel, and then paste this selected area directly into a PictureBox that I have just to the right of the Panel. My problem is that my code at the moment is not working correctly, when I try to paste the Bitmap that I am creating from the panel I am getting a big red X in the PictureBox instead of the actual image. I

问题 I am using thrust::sequence(myvector.begin(), myvector.end(), 0, 1) and achieve good ordered list like: 0, 1, 2, 3, 4 My question is how can I achieve such a list below (the best way?) 0, 0, 0, 1, 1, 1, 2, 2 ,2, 3, 3, 3 I know how to make it with functors, so please do not try to answer it with functor. I want to learn if there is an optimized way for it in Thrust, or am I missing a simple way.. 回答1: Something like this: thrust::device_vector<int> myvector(N); thrust::transform( thrust::make

问题 I am describing my work process bellow: I get image files from a directory. Creating a PictureBox array for displaying the images. Creating a Image array from the files that I got from the directory. I am creating this array for making the image source of PictureBox . I am copying the files to another directory. By this: File.Copy(allFiles[i],fullPath+fullName+"-AA"+nameString+ext); Now I want to delete the files from the directory. For this I am doing this: File.Delete(allFiles[i]); But its

问题 I have found the following code after a lot of research and it does a little of what I want it to do except I don't know how to specify the criteria to reference a range of cells instead of just one single criteria. I am also trying to copy the records and append them to the end of the rows of the matching records in Sheet1. This code only copies the records to Sheet3 so they aren't pasted with their corresponding rows in Sheet1 like I want. Sub copytosheet() Dim sRng As Range, cell As Range

问题 I started looking at robocopy yesterday to try to copy and overwrite a file from one destination to many remote computers. I've tried Robocopy to copy files to a remote machine but it doesn't work. I get the same error as the person in the link. Does anybody have any suggestions or lead me in the right way ? thank you so much ! 回答1: You could just use PowerShell for this. It has an inefficiency issue wherein it would copy one at a time but that shouldnt be an issue for 50ish machines. This

问题 I'm having problems copying a multidimensional vector, I've tried many things but this is the last one: vector < vector < int > > a; vector < vector < int > > b; a.resize(10); b.resize(10); a[0][0] = 123; copy( a.begin(), a.end(), back_inserter(b) ); cout << b[0][0]; I'm trying to do a recursive loop that counts all possible routes in a grid within 10 moves. I'm trying to create a vector called current_path which would hold the current path for each recursion, when the current_path has 10

问题 I'm working on a problem which requires me to copy a binary search tree recursively and to return the tree. I am coding in the binary search tree class, so it will copy whatever binary search tree it is called on. The requirements say that the private method must have a return type of Entry<E> and a parameter of type Entry<E> . The problem I'm running into is getting multiple entries added to the tree. Here is what I currently have: public BinarySearchTree<E> rcopy(){ BinarySearchTree newTree

问题 I have created a simple Powershell script to copy files during a deployment from a target directory to a source directory and I would like to exclude a list of files. The caveat however is that I would like the ability to exclude files only from a sub directory if specified. This is the snippet I'm using to perform the copy and exclude a list of files: $SourceDirectory = "C:\Source" $DestinationDirectory = "C:\Destination" $Exclude = @("*.txt*", "*.xml*") Get-ChildItem $SourceDirectory
