請問我設計一個使用dbexpress 設計一個dll檔有form表單而在dll檔內加入一個datamodule可是當我的dll檔表單加入clientdataset元件在執行時open連結datamodule內的連結程式時就會發生錯誤訊號

unit frmCustomer;
interface
uses
Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
Dialogs, StdCtrls, Grids, DBGrids, DB, DBClient, Provider;
type
TformCustomer = class(TForm)
Button1: TButton;
Edit1: TEdit;
Memo1: TMemo;
DataSetProvider1: TDataSetProvider;
ClientDataSet1: TClientDataSet;
DataSource1: TDataSource;
DBGrid1: TDBGrid;
procedure Button1Click(Sender: TObject);
private
{ Private declarations }
public
{ Public declarations }
end;
var
formCustomer: TformCustomer;
ok:boolean;
procedure showCustomerForm;export;
implementation
uses DataModule;
{$R *.dfm}
procedure showCustomerForm;
begin
formCustomer:=TformCustomer.Create(application);
try
if formCustomer.ShowModal=mrYes then
ok:=true;
finally
formCustomer.Free;
end;
end;
procedure TformCustomer.Button1Click(Sender: TObject);
begin
clientdataset1.open; <=== 在datamodule的元件連結及open都沒問題但只要clientdataset元件一open就會有問題
end;
end.
