As many of you know I'm writing a TCP/IP server with multiple threads
handling multiple short conversations (submit a short string, send back
a sort string). Threads are created as needed to handle a new
connection request and terminate after the exchange is complete.
I got a new request for the program. I've been asked the the program
write all the strings it receives and sends to a log file. I'm
concerned about all these threads stepping on each other writing to a
common file. Any ideas?

Can you use a "busy" variable as a flag and set to true when writing then
false when not writing. Should be able to control the simultaneous writing
using Synclock on the flag.

Hello cj,
You can create a single class that writes the log file. This class must be thread safe through synchronization mechanisms. Then your threads can use that class to write to the log.

I think that's what I'm going to do.

Hi
Also I think as Dennis suggest, we can use the threading synchronize
mechanism to make sure there will be only one thread access to the log file
in the meantime.
You may take a look at the link below.

Hello,
I have an application that processes thousands of files each day. The
filenames and various related file information is retrieved, related
filenames are associate and placed in a linked list within a single object,
which is then placed on a stack(This cuts down thread creation and deletions
roughly by a factor of 4). I create up to 12 threads, which then process a

Hi, how can I create multiple new file handles of a file without having to

I have a file that will be accessed by multiple threads in my application,
each time a thread try to do something with the file, the thread will create
a new file handle. However, if I specify FileShare.ReadWrite, other process
can also open that file. I tried FileShare.Inheritable but it doesn't work.

I have a multithreaded windows NT service application (vb.net 2003) that I

populate it, and then export it to a PDF.
It works fine so far....

hi all
am updating the same file in ftp, through multiple clients, but am
scared that two clients may open the same file at a time, and try
updating, then the data updated by one data will be lost.
So i have to provide some lock mechanism to that file in ftp, so how
can i lock it, if one client opens it for updating, so that till it
gets relased it cannot be updated by other clients.
Could u please suggest me the simple solutions...

how do i request a download which starts directly at 500000th byte...

Hi -
I am attempting to write lines to a file at high volume, multiple threads.
Here is my scenario:
(initial "WriteToFile" object created via a parent multithreaded process,
which receives files, can call custom code for each file received - much like
BizTalk)
1. Receive multiple files, each file received creates a "WriteToFile" object

Hi there... I have a huge text file that needs to be processed. At the
moment, I'm loading it into memory in small chunks (x amount of lines)
and processing it that way. I'd like the process to be faster, so I'd
like to try creating multiple threads, and having them load different
chunks of the file at the same time and process it asynchronously.
Is it possible to do something like that, and if so, what would be
needed to do so?

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.
