I have serious problem with Replace-command and WinNT4.
In the code below i have emphesized the failing command.
What happens is that very randomly this Replace is only
partially performed.
The resulting buffer (15000 bytes give and take 1024 bytes)
is translated into EBCDIC rest remain in ASCII
Sometimes 5000 bytes sometimes 14000 bytes are translated.
It seems to me that NT4 is switching away from this code before
the memory is completely updated (Replace is performed),
and when it comes back again it seems not to carry on with Replace.
This code is working on Win95 but it is in the main EXE-file
Running without problem for a year.
This code seems to be working on WIN2000
(havent been able to prove otherwise) The code is in a DLL
This code does not work in NT4 SP6a (code in DLL)
My customer runs this code on both WIN95 and WINNT4
The problem seems to occure when VNC a TCP/IP based remote-access
program is run on the machine. But it also sometimes happens if I
start Explorer or some other program.(with VNC unloaded)
I need a very quick sulotion to this problem.
Can someone help?
Can I prevent context-switching around the relace-command?
