UHTTP->DUMP_FILE_CONTENTS:File not created

Author: i2stiller@gmx.de (istiller)

Hi freaks Just doing a few file transfer by UHTTP, which looks pretty good. BUT ... But then sometimes, UHTTP->DUMP_FILE_CONTENTS does not create a file on disk, even if GET_INFO("length) returns the correct length. A retry with exactly same paramters dumps the file Any idea? Ingo   Here a few lines of debug messages:

Hi Ingo, I had a quick look, but (as far as I can see) this has not been reported before. In case the operation DUMP_FILE_CONTENTS returns a positive value (and it's equal to the value returned by GET_INFO(“length)) then it apparently was successful and the specified file should have been created. Have you already tried to add a delay after executing DUMP_FILE_CONTENTS and before you check if the file exists? Maybe this is some sort of caching problem? I’ve heard from a colleague that it’s (e.g.) possible that Windows might write files with a delay (because of disk write caching). Here’s some info I’ve found on this topic: > HOW TO: Manually Turn Disk Write Caching On or Off Hope this helps. Daniel
