Access variable from one form to another

[DeddyH]

I think we need the code of the "Person1"-method. Maybe you want to do a call by reference but actually do a call by value?

[Blup]

The PersonID can alternatively be determined from a query:

Delphi-Quellcode:

unit unit1;

interface

type
  TForm1 = class(TForm)
    {...}
  private // <- for use self
    function GetMyPersonID: Integer;
    procedure SetMyPersonID(AValue: Integer);
  public // <- for use to other
    property MyPersonID: Integer read GetMyPersonID write SetPersonID;
  end;

var
  Form1: TForm1; // <- Instance of TForm1

implementation

procedure TForm1.SetMyPersonID(AValue: Integer);
begin
  FQuery.FieldByName('MyPersonID').AsInteger := AValue;
end;

procedure TForm1.GetMyPersonID: Integer;
begin
  Result := FQuery.FieldByName('MyPersonID').AsInteger;
end;

Hi,
i have followed what you have suggested but i still got the value '0' .
Now, i wanna do the work in same Unit mot from another

Code:

Procedure TForm1.AddDateTime(Sender:Tobject;  AEvent: TcxSchedulerEvent);
begin

Query.Close();
    QueryKalender.SQL.Text:= 'INSERT INTO Table'
      '(Name`, `NEWID` ..) ' +
    'VALUES ( ' :Name, :NEWID);';

Query.ParamByName('NEWID').AsInteger:= AEventID;
    Query.ExecSQL();
    Query.Close();

  end;

Procedure TForm1.OnDragDrop(Sender, Source: TObject; X,
  Y: Integer);

begin
//here i would like to use the value of AEventID; 
//i cannnot call the procedure AddDateTime(Sender,TcxSchedulerEvent);
//becasue the parameter is different, how can i overcome it ?
end;

Hi, now its working fine :) i have written the follwoing

Code:

procedure TForm1.SetMyPersonID(AValue: Integer);
begin
  FQuery.FieldByName('MyPersonID').AsInteger := AValue;
end;

procedure TForm1.GetMyPersonID: Integer;
begin
  Result := FQuery.FieldByName('MyPersonID').AsInteger;
end;

is that ok to write like this, i mean normally in sql query need to query.sql.add/query.sql.open/close... but in this case it is working fine should i need to write the whole query or is that also okay just to write only

Code:

Result := FQuery.FieldByName('MyPersonID').AsInteger;
