Dear All,
I have two units, Unit1 and Unit2 , i would like to
access a boolean from Unit1 to Unit2 , i have tried it in the following way, but i have got the error "Zugriffsverletzung bei Adresse 023C4B58 in Modul 'Test.exe'. Lesen von Adresse 0000"
Code:
//Unit1
Unit Unit1
type TCalculation = class(TForm)
private
protected
FNewvalue: Boolean;
public
property Newvalue: Boolean read FNewvalue;
end;
//Unit2
Unit Unit2
type Taccounts = class(TForm)
interface
uses
Unit1
private
protected
public
procedure Checkvalue(Sender: TObject);
end;
implementation
procedure Taccounts .Checkvalue(Sender: TObject);
var
f : TCalculation ; // i have created an instance of TCalculation
begin
if f.Newvalue = True then // i have called the boolean
//check the condition
End;
could you please tell me ,how can i make it works?
