Data Source

[pronny31]

Habe ich gemacht und trotzdem kommt die Speicherverletzung !

Delphi-Quellcode:

unit mainUnit;

interface

uses
  Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
  Dialogs, StdCtrls, DBCtrls, DB, IBDatabase, IBCustomDataSet, IBQuery,
  IBTable, Grids, DBGrids;

type
  TmainForm = class(TForm)
    IBDatabase1: TIBDatabase;
    IBTransaction1: TIBTransaction;
    DataSource1: TDataSource;
    DBMemo1: TDBMemo;
    IBQuery1: TIBQuery;
    procedure FormCreate(Sender: TObject);
  private
    { Private declarations }
  public
    { Public declarations }
  end;

var
  mainForm: TmainForm;

implementation

{$R *.dfm}


procedure TmainForm.FormCreate(Sender: TObject);
begin
        IBQuery1.Open;
        IBQuery1.SQL.add('Select Memo1 from pcbeinstellungendefault where zaehler = 10');
        DataSource1.DataSet:= IBQuery1;
        MainForm.DBMemo1.DataSource := MainForm.DataSource1;
        MainForm.DBMemo1.DataField := 'MEMO1';
end;

end.
