Hi Bob.
Thanks for the answer.

That's right. I don't have access to his machine so I don't know yet
where the error is.
This is why I want to create a new account on my machine using UNICODE
characters.
There are 10000 ways for your program, that's running like a ballerina
in your computer, to crush like a hammer in user's computer.
I suppose that the path to the INI file is invalid because of those
'????' signs it returns.
So, my program can't read/write the INI file(s).
I get the path for 'App Data' using the GetSpecialFolder which I suppose
is able to return UNICODE strings. The problem is that Delphi does not
support very well UNICODE.
So I don't know if it worth to rewrite large pieces of my program to
support UNICODE.
If the problem will appear only when writing the INI files, then will be
simple because I can get rid of those INI files and write to registry
(Local_User).
But I want also to write text files (lists and databases). It won't be
nice to stick all that information in user's registry (in most cases I
don't have to write uninstallers for my applications because I leave no
traces behind me).
Under Win98 I never had problems because I put that information right in
the application's folder.
But now WinXP wants me to use user's profile (the 'App Data' folder),
which may contain UNICODE chars (God knows what they may put in it later).
Is this a dead end?
function GetAppDataFolder(AppName: string): string;
begin
if (OS_WinPlatform<>
VER_PLATFORM_WIN32_NT) {
GetWindowsPlatform >= Win2000 }
OR
UserHasAdminRights
{ Daca userul are drepturi de administrator atunci prefer sa scriu in
directorul aplicatiei }
then Result:= ExtractFilePath(Application.ExeName)
else Result:= GetSpecialFolder(CSIDL_APPDATA)+
AppName;
if NOT DirectoryExists(Result)
then ForceDirectories(Result);
end;
