flush

Overview I have a Client-Server whereby I have the streamWriter.WriteLine(messageToClient); on the server sending large messages. The streamReader.ReadLine(); on the client is reading the 2000 length messages fine. The issue here is the streamWriter.Flush() has no affect on the larger messages, because what I am aiming for is the server to be able to switch between the buffers flushing directly (having a fluid server message output) and not (the server response would be jumbled together until it reaches the buffers limit to flush). Question: I am thinking that the buffers are auto flushing

So, I have this project that creates multiple instances of a class, and list them. At some point, the instanced class is not needed anymore. How can I flush it ? So far, it doesn't happen, even when the class has nothing to do anymore (if it had been a single static class, the program would have shut down), it's still in my list, and its public variables are still available ... You can have your instances raise an event (OnInactivated, say). The list class should add a handler for such events when the item is added to the list (subclass or encapsulate a list and override the Add method). When

Is there a way in python to flush a socket once a request has been sent and the information has been obtained correctly? I have a socket that is used to send different commands at different times, so I was just wondering if this was possible. Any help would be greatly appreciated. Nick Craig-Wood In general no is the answer - you can't flush a TCP socket. All that is under the control of TCP.

Here is the code (valid C and C++) #include <stdio.h> int main() { printf("asfd"); // LINE 1 return 0; } If in line 1 I put segfaulting expression the program would just crash without printing anything (as expected). But why is the above code printing "asdf" and not exiting without buffer being flushed? What is under the hood and why does it work as expected? This is accomplished by these two sections in the C++ language specification: [basic.start.main] A return statement in main has the effect of leaving the main function and calling exit with the return value as the argument. and [lib

I have a simple C++ program that uses cout and printf to log stuff and it is only showing at the end when the program is closed but if I'm stepping through the program using debug nothing is shown. Did anybody have this problem? If you're practicing c try fflush , if c++ try cout << endl; each time you want to print. 来源： https://stackoverflow.com/questions/3316195/xcode-not-showing-console-output-how-do-you-flush-the-console

JPA is essentially an higher abstraction of JDBC. EntityManager has an API setAutoFlushMode. It can be set to AUTO or COMMIT. What's th equivalent of this in JDBC terms? thanks JDBC has auto commit as well. They're both for configuring whether the library should automatically commit to the database. JDBCs auto-commit is very simplistic, it will commit every update to the database immediately. Without auto-commit, changes aren't committed until the commit method is called. JPA AUTO causes a flush to the database before a query is executed. Simple operations like find don't require a flush since

Hi Sometimes I need to do some SQL tuning task, I usually do such tests on my test db. After I excute a sql statments, I want to flush the buffer cache which containing SQL statements and sql result, just like the command in Oracle "Alter system flush buffer_cache" Is PG server provide a commond of this? viksit Check out this SO answer, See and clear Postgres caches/buffers? If you're developing on OSX (I haven't tested on linux), you can use purge command to force disk cache to be purged (flushed and emptied). Then run your SQL query again and it should execute as if it were the first time.
