Question

How to override TIniFile.Create constructor ?

This code is not working because Create is static:

  TMyIniFile = class(TIniFile)
   protected
   public
     constructor Create  (CONST AppName: string); override;  <------ Error 'Cannot override a non-virtual method' 
   end;

Answer 1

You cannot override the constructor of TIniFile since it is not virtual. The ini file classes do not use virtual constructors.

You simply need to remove the override from your code.

TMyIniFile = class(TIniFile)
public
  constructor Create(const AppName: string);
end;

Implement it like this:

constructor TMyIniFile.Create(const AppName: string);
begin
  inherited Create(FileName);//I can't tell what you need as FileName
  FAppName := AppName;
end;

When you need to create one you do so like this:

MyIniFile := TMyIniFile.Create(MyAppName);
