小问题，难！

[cqzd]

ll_cnt_array = UpperBound(this.Control[])
FOR li_for_array = 1 TO ll_cnt_array
IF this.Control[li_for_array].Tag = ls_tqh THEN
IF ls_qx = 'T' AND typeof(this.Control[li_for_array]) = commandbutton! THEN
//this.Control[li_for_array].Enabled = TRUE
ELSE
//this.Control[li_for_array].Enabled = FALSE
END IF
END IF
NEXT
注释的两行编译不了，换成VISIBLE则可以，如何解决？
