>> then I use those as needed.. then write them all out, but if I am<br>
understanding it correctly could I just use the memory version of the ini<br>
file directly?<br>
<br>
In my case, I have a protocol where some parameters must be archived and<br>
IniFiles are handy when I need to do some eye inspection on them.<br>
Currently, I use IniFiles as in-memory to be archived and<br>
IniFile.ReadSectionValues('Section', TStringList(Instance)) for dynamic<br>
stuff.<br>
<br>

To try to resolve your issue you should use TMemIniFile and invoke Rename()<br>
before freeing the TMemIniFile (or invoking UpdateFile explicitly) to save<br>
to the temporary file.<br>
<br>
TMemIniFile is just TIniFile with some extra methods and with CacheUpdates<br>
defaulting to True. They parse the whole ini file in the constructor, so<br>
values are always read from memory.<br>
<br>
Regards,<br>
Fl?vio<br>
<br>
P.S. Although these classes are meant for compatibility with<br>
Delphi/Windows, maybe they should provide extra methods with correct<br>
exception handling and "atomic" saving with temporary file?<br>
Or maybe someone can recommend alternatives?<br>
