file

问题 There are a number of sync and async operations for files in dart:io: file.deleteSync() and file.delete() file.readAsStringSync() and file.readAsString() file.writeAsBytesSync(bytes) and file.writeAsBytes(bytes) and many, many more. What are the considerations that I should keep in mind when choosing between the sync and async options? I seem to recall seeing somewhere that the sync option is faster if you have to wait for it to finish anyway ( await file.delete() for example). But I can't

问题 I would like to create a vbscript to open a notepad text file I saved and keep this notepad text file on top of all other windows either until i minimise it or close it. I want to create a reminder in tasks then so it pops up every 30 minutes or so and reminds me but so when i browse it does not go in the background. Greatly appreciate any help. Dim oShell Set oShell = WScript.CreateObject ("WScript.Shell") oShell.run "notepad.exe C:\Users\***USER***\AppData\Roaming\Microsoft\Windows\Start

问题 I found a different way to write data, which is faster than normal unix write function. Firstly, ftruncate the file to the length we need, then mmap this block of file, finally, using memcpy to flush the file content. I will give the example code below. As I known, mmap can load the file into the process address space, accelerating by ignoring the page cache. BUT, I don't have any idea why it can fast up the writing speed. Whether I write a wrong test case or it can be a kind of opti trick?

问题 I have a form with html browse type and a submit button. I chose a file using browse button and submit the form. On form submission following code is called. $conn_id="myid"; $conn_id = ftp_connect ( 'server' ); $ftp_user_name="username"; $ftp_user_pass="password"; // login with username and password $login_result = ftp_login ( $conn_id , $ftp_user_name , $ftp_user_pass ); // check connection if ((! $conn_id ) || (! $login_result )) { echo "FTP connection has failed!" ; exit; } else { echo

问题 I have a .NET Core 2.0 web app running on an Azure App Service instance. When I try to upload a file using file.CopyToAsync() , the upload fails with no diagnostic output if the file is larger than 128kB. Some photo types like png just get chopped at 128kB, even when they're several mB in size. When I try running locally, I can upload much larger files into my wwwroot/etc... folder on my local machine, so the problem seems specific to Azure App Services. I've looked up documentation on file

问题 I want to store an object from my class in file, and after that to be able to load the object from this file. But somewhere I am making a mistake(s) and cannot figure out where.
