To Flush or Not to Flush

Tom
Do I really need to flush a streamwriter? It appears to work either way.

Dim sw As StreamWriter
Dim strFullPath As String = "C:\Temp\Test.t xt"

If File.Exists(str FullPath) Then
sw = File.AppendText (strFullPath)
Else
sw = File.CreateText (strFullPath)
End If

sw.WriteLine("H ello its me")

'sw.Flush()
sw.Close()

Close always Flush'es first.

You would only need to flush if you were keeping the StreamWriter open and
wanted to make sure that all of your previous writes were safely on-disk.

I'm trying to write a script to weekly remove MySQL logs, the general, error and binary log files. Following the MySQL documentation, I've written a script that moves all current log files, then executes mysqladmin flush-logs. My question is this on the binary logs (bin.001, bin.002, etc.): once these are removed and flush logs is executed, the binary log files start over with bin.001.

System.IO.StreamWriter Close or Flush method to shut down the computer in such a way that just part of the file is written? or an empty file is written? Also if the Close or Flush is to a streamwriter writing to a network share, is it possible for the network to go down in such a way that the tartet file is only partialy written? or are there some kind of check sums to prevent this.

I'm aware that there is no ANSI (or POSIX, or any standard, to my knowledge) way of flushing stdin or any other application-level input buffer, but if anyone knows a hack or a non-portable way to do this, no matter how obscure or arcane, I'd appreciate it.

Guys, I need to send some info to my client while I'm processing some stuff. The flow will be something like : -process -response -process -response .... I imagine to use response.flush (as I did on ASP) but it does not work. See my test code, after sending 2 lines on response, I'm simulating a processing time before sending other 2 lines.

i'm working on improving the IO for the software project i'm working on to do two extra things. first, i'm going to add HDF5 functionality, and second, add the ability to write binary output. the software is computational science where a lot of stuff is going to be calculated and written to a file. e.g. could be up to gigabytes of data. my question has to do with the latter -- and how often i need to call "flush" on the stream. what I...

Hello! I have noticed that after (sucessfully) executing the command: FLUSH PACKAGE CACHE DYNAMIC the dynamic SQL statement cache is not completely cleared (some of the dynamic SQL statement elements are not reset). For example, looking at the dynamic SQL snapshot I see a certain SQL statement that has been executed a number of times and has read a (big) number of rows. Then I execute the "FLUSH PACKAGE CACHE DYNAMIC" command.

Hello folks, I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>". The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed. This is as boiled down as I can make it. Here is my compilation command: g++-12 -std=c++20 -Wnarrowing bit_field.cpp Here is the code in...

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
