During the migration of our scripts to Kix2001 beta 1 we
discover a timings problem.
What are we doing:

• setfileattr(file,128)
  
• del file
  
• writeprofilestring(file,.....)
  
• setfileattr(file,7) which means: file will get ReadOnly, Hidden & System
  attributes.
  

Result (see line 290): The system cannot find the file specified.

remarks:

• remove line 268 means the file becomes the RO,H,S attributes
  before the new information of writeprofilestring has put
  to the file.
  
• we discover this problem by using our local C-drive as destination
  location. normally we are writting those information to user's
  home directory.
  

Script code which is a part of our script logon.kix 2.00, which
has been check with kixstrip.exe. We were using the options
/debug /block_check /show_errors:

A possible problem can created by a very fast workstation. We are running it on a Pentium 3 1000 MHz with DIMM 133.
Greetings.

If you put a SLEEP 1 in there, does it help?

cj

The speed of our computer wasn't the problem.
The scripts runs correct for windows NT and Windows 2000.
Windows 95 / 98 have this problem.
Our work-around is to check first for the availibility of the file before trying to change the attributes of it.
Greetings.

In contrast, NT/2000 has a better cache algorythm and will flush the buffer prior to altering the attributes.

About the only real way around this is for Kixtart to forcibly flush the buffers at the end of all file write operations. Of course that would require a change at source code level.

Problem checked. Situation unchanged but it isn't a kix problem.
Greetings.
