hello everyone.
i'm from china P.R.
my english is very pool.

I have edit the frxDCtrl.pas , on it I have add some components (TfrxRadioGroupControl , TfrxDBGridControl)
and edit below
frxObjects.RegisterObject1(TfrxDateEditControl, nil, '', '', 0, 20); //add by hz
frxObjects.RegisterObject1(TfrxImageControl, nil, '', '', 0, 3); //add by hz
frxObjects.RegisterObject1(TfrxBevelControl, nil, '', '', 0, 33); //add by hz
frxObjects.RegisterObject1(TfrxBitBtnControl, nil, '', '', 0, 45); //add by hz
frxObjects.RegisterObject1(TfrxSpeedButtonControl, nil, '', '', 0, 46); //add by hz
frxObjects.RegisterObject1(TfrxMaskEditControl, nil, '', '', 0, 47); //add by hz
frxObjects.RegisterObject1(TfrxCheckListBoxControl, nil, '', '', 0, 48); //add by hz
frxObjects.RegisterObject1(TfrxRadioGroupControl, nil, '', '', 0, 49); //add by hz
frxObjects.RegisterObject1(TfrxDBGridControl, nil, '', '', 0, 50); //add by hz

so , i edit the form frxDesgn and edit the ObjectsTB1's width ,then these components work OK,
but now I went to add TDataSource as TfrxTDataSourceControl ,there some difficulty for me, can someone help to write this code for me?
Thanks!
