tips:

• EventHandler 取消原窗体调用：

   FormControlCancelableSuperEventArgs cancelSuperEventArgs = e as FormControlCancelableSuperEventArgs;
   cancelSuperEventArgs.CancelSuperCall();

• 临时表

   sysTableLookup.parmQuery(query);
   sysTableLookup.parmTmpBuffer(TmpTableFieldLookup);
   sysTableLookup.performFormLookup();
