    replied to FTP a dynamic file with year and month
    thank your reply. I think that works.

    Here another question rises due my further investigation on not only downloading a file through ftp, but also through http. do you have any idea how to use NT commands to download a file from a web like http://www.mydomain.co m/data/datafile.zip ?

    Thanks in advance.

    FTP a dynamic file with year and month

    Do somebody know how to come up with a dynamic file name when ftp it ? I need to download a monthly updated file. The file name appears like datafile_yyyymm .zip where yyyy mean year 2008, and mm mean month 02.

    I think the problem has been resovled. The problem I guess is because I did not close the StreamWriter. When I add code to close the streaWirter, the problem goes away.

    Thanks for all you guys' comments and help.

    Actually there is only one batch log file of the 7 batch log files missing the log message from middle somewhere from where there are no any logs....

    Thank your reply.

    But I have no space problem. The space still has 10 GB. No security, permission problem, because it has already been written several hundreds bytes log. I used to guess it is a problem of dead lock, because I use multithreading. However I already took care of the thread safe issue. Because of the complication of the multithread logging, so it is still the candidate. Another candidate is buffer flushing problem....

    StreamWriter is not reliable

    for who have any idea about my question.

    I have a multithread middle tier engine and use StreamWriter to log events to console and files. I run the engine for whole night (6 - 10 hours) and there are 8 batch log files generated. Sometimes some log files (one or two of 8) is cut off on the very last portion. I thought it might be because buffer is not flushed out. But I use AutoFlush and Flush. The problem still exist. Do some body...
