copy

If slicing does not create a copy of a list nor does list() how can I get a real copy of my list?

问题 I am trying to modify a list and since my modifications were getting a bit tricky and my list large I took a slice of my list using the following code tempList=origList[0:10] for item in tempList: item[-1].insert(0 , item[1]) del item[1] I did this thinking that all of the modifications to the list would affect tempList object and not origList objects. Well once I got my code right and ran it on my original list the first ten items (indexed 0-9) were affected by my manipulation in testing the

Hook into the Windows File Copy API from C#

别等时光非礼了梦想. 提交于 2020-02-01 08:57:48
问题 Is there a way to hook into the Windows File Copy API from C#? I'm aware this would require unmanaged code, but a code sample or starter would be helpful. I've already seen the C++ code, but it's all greek. UPDATE: I apologize, I should have been more clear about my intentions. I wish to actually change the copy feature of Windows to be more rigid (e.g. allow queing, scheduling, handle restarts, pauses, etc.). When I said hook, I meant API hook so that when someone starts a copy I get the

How can I copy a vector to another location and reuse the existing allocated memory?

问题 In C++, to copy the contents of a vector to another vector we use the assignment operator dest = src . However, in Rust src would be moved into dest and no longer usable. I know the simplest answer is to do dest = src.clone() (for the sake of this question we'll assume T in Vec<T> is Clone ). However - if I'm understanding correctly - this creates a brand new third vector with the copied contents of src and moves it into dest , throwing away dest 's dynamically allocated array. If this is

Ag-grid angular copy menu option not available

泪湿孤枕 提交于 2020-01-25 10:13:11
问题 I am using ag-grid with angular 8 with an enterprise license. For some reason, the default "copy", "copy with headers" context menu items are not available. Only the "Export" item is showing up. Other enterprise features are working fine, but I can't seem to figure out how to enable "copy". I'm not sure what I can try next, I've tried using different imports, disabling features, ... The ag-grid-angular tag: <ag-grid-angular #agGrid style="width: 800px; height: 500px;" class="ag-theme-balham"

Failing to copy one cell to another cell using Destination Copy

问题 Range("A1").Copy (Range("E5")) That fails, but if I explicitly define the destination range as a Destination, like the following, it works. Range("A1").Copy Destination:=Range("E5") If I give a Worksheet reference for my destination, like the following, it also works: Range("A1").Copy (Worksheets("Sheet1).Range("E5")) Why is the simplest form, not working, and giving me Runtime Error 1004: "Copy method of Range class failed" instead? 回答1: The difference between Range("A1").Copy (Range("E5"))

Undo a botched command prompt copy which concatenated all of my files

问题 In a Windows 8 Command Prompt, I had a backup drive plugged in and I navigated to my User directory. I executed the command: copy Documents G:/Seagate_backup/Documents What I assumed was that copy would create the Documents directory on my backup drive and then copy the contents of the C: Documents directory into it. That is not what happened! I proceeded to wipe my hard-drive and re-install the operating system, thinking I had backed up the important files, only to find out that copy

How to Copy a Folder from a TEST App Service to a LIVE App Service on Azure

问题 In my Azure DevOps Pipeline I would like to copy a folder e.g. Media from 1 environment/app service, say TEST to another environment/app service say Live. The Media folder in TEST may get updated AFTER the Ci/cd build has been deployed to the TEST environment - just to exclude answers that might suggest putting it in Git and including it as a Build artifact. EDIT - Clarification on using the accepted answer. My repo contains the given powershell script in the accepted answer as : azure/Copy
