Thanks for answers to everybody.
What I wanted to do, was to be able to get a constant string (the
Application.Title) from any unit of my application (and maybe also from
external units/VCLs) and to use this constant (the name of the
application) to create a folder in 'application data' where to write the
INI files.
For example:
function SaveIniFile( s: string ): string;
begin
Result:= GetAppDataFolder+ s+ 'MyINI.ini';
end;
Usage:
Application.Title= 'Bitmap Resampler';
GetUserPath(Application.Title);
The result should be something like:
c:\Documents and Settings\USER_NAME\Application
Data\Bitmap Resampler\MyINI.ini
Anyway I abandoned the idea and I used a simple constant like
const AppTitle= 'Bitmap Resampler' that solved the problem.
Anyway, it is still strange that reading/accessing the
'Application.Title' inside the DPR file (at design time) will make the
project impossible to load in IDE!
