uj5u.com熱心網友回復：
你的代碼不完整，創建Tabpage應該這樣：procedure TMainForm.AddSheetEx(URLStr,sName:String;K:integer);
var TabSheetEx: TTabSheetEx;
begin
Try
iFlag := iFlag+1;
SetLength(TabSheetExList, iFlag+1);
TabSheetEx := TTabSheetEx.Create(PageControl1);
TabSheetExList[iFlag]:=TabSheetEx;
PageControl1.ActivePage := TabSheetEx;
with TabSheetEx do
begin
PageControl := PageControl1;
Tag:=iFlag;
Caption := sName;
EWB := TEmbeddedWB.Create(TabSheetEx);
TOleControl(TabSheetEx.EWB).Parent := TabSheetEx;
with EWB do
begin
Tag:=iFlag;
LoadSettings;
Align := alClient;
Visible := True;
TheaterMode:=true;
OnStatusTextChange := StatusTextChangeEvent;
OnNewWindow2 := NewWindow2Event;
OnNewWindow3 := NewWindow3Event;
OnDownloadComplete := DownloadCompleteEvent;
OnCommandStateChange := CommandStateChangeEvent;
if k=1 then
OnDocumentComplete:=EmbeddedWB1DocumentComplete;
Go(URLStr);
end;
Show;
TabSheetEx.EWB.SetFocus;
end;
except
TabSheetEx.Free;
end;
end;
