Re: String access error in class

I have included a stripped down version of a class I am using to store configuration data in an ini file.

This works when I am using it from a simple console app. But when I include it in a larger project, the constructor throws this error:

'Access violation at address 004050FC in module 'app.exe'. Write of address 00000008'.

This happens on the line: ComputerName:='test';

Obviously 00000008 is not a valid address. But I thought delphi handles string address automatically.

What have I done wrong?

Thanks.



unit Configuration;

interface

uses windows,inifiles,sysutils;

type
TConfig = Class(TObject)
public
FileName:string;

ComputerName:String;
//...

constructor Create(); overload;
constructor Create(FN:String); overload;

//procedure saveFile(); overload;
//procedure saveFile(FN:string); overload;

//function checkErrors():string;
//procedure fixErrors();


end;


var

IniFile : TIniFile;

implementation

constructor TConfig.Create(Fn:string)overload;
begin

IniFile := TIniFile.Create(Fn);
ComputerName:='test';

filename:=fn;
//savefile(fn);

end;

constructor TConfig.Create()overload;
begin
Create(Paramstr(0)+'.ini');
end;

end.
Try calling the inherited create first maybe?
