有些程序我不明白 可以給我解釋一下以及有什作用 const visiblebuttonarray:array[0..9] of tbuttonset=([nbfirst], [nbprior], [nbnext], [nblast], [nbinsert], [nbDelete], [nbedit], [nbpost], [nbcancel], [nbrefresh]); var Form2: TForm2; Procedure DisableBtn(); Procedure BtnDeox(); implementation {$R *.DFM} procedure disablebtn(); begin form2.bitbtn1.enabled:=false; form2.bitbtn2.enabled:=false; form2.bitbtn3.enabled:=false; form2.bitbtn4.enabled:=false; form2.bitbtn5.enabled:=false; form2.bitbtn6.enabled:=false; form2.bitbtn7.enabled:=false; form2.bitbtn8.enabled:=false; form2.bitbtn9.enabled:=false; end; procedure btndeox(); begin form2.bitbtn1.enabled:=false; form2.bitbtn2.enabled:=false; form2.bitbtn3.enabled:=true; form2.bitbtn4.enabled:=true; form2.bitbtn5.enabled:=false; form2.bitbtn6.enabled:=false; form2.bitbtn7.enabled:=false; form2.bitbtn8.enabled:=false; form2.bitbtn9.enabled:=false; end; procedure TForm2.CheckBox1Click(Sender: TObject); //First begin with sender as Tcheckbox do begin //Tag has no predefined meaning checkbox1.tag:=0; if checked then DBNavigator.visiblebuttons:=DBNavigator.visiblebuttons visiblebuttonarray[tag] else DBNavigator.visiblebuttons:=DBNavigator.visiblebuttons - visiblebuttonarray[tag]; end; end; procedure TForm2.CheckBox2Click(Sender: TObject); begin with sender as Tcheckbox do begin checkbox2.tag:=1; if checked then dbnavigator.visiblebuttons:=dbnavigator.visiblebuttons visiblebuttonarray[tag] else dbnavigator.visiblebuttons:=dbnavigator.visiblebuttons - visiblebuttonarray[tag]; end; end; procedure TForm2.CheckBox3Click(Sender: TObject); begin with sender as Tcheckbox do begin checkbox3.tag:=2; if checked then dbnavigator.visiblebuttons:=dbnavigator.visiblebuttons visiblebuttonarray[tag] else dbnavigator.visiblebuttons:=dbnavigator.visiblebuttons - visiblebuttonarray[tag]; end; end; procedure TForm2.CheckBox4Click(Sender: TObject); begin with sender as Tcheckbox do begin checkbox4.tag:=3; if checked then dbnavigator.visiblebuttons:=dbnavigator.visiblebuttons visiblebuttonarray[tag] else dbnavigator.visiblebuttons:=dbnavigator.visiblebuttons - visiblebuttonarray[tag]; end; end; procedure TForm2.CheckBox5Click(Sender: TObject); begin with sender as Tcheckbox do begin checkbox5.tag:=4; if checked then dbnavigator.visiblebuttons:=dbnavigator.visiblebuttons visiblebuttonarray[tag] else dbnavigator.visiblebuttons:=dbnavigator.visiblebuttons - visiblebuttonarray[tag]; end; end; procedure TForm2.CheckBox6Click(Sender: TObject); begin with sender as Tcheckbox do begin checkbox6.tag:=5; if checked then dbnavigator.visiblebuttons:=dbnavigator.visiblebuttons visiblebuttonarray[tag] else dbnavigator.visiblebuttons:=dbnavigator.visiblebuttons - visiblebuttonarray[tag]; end; end; procedure TForm2.CheckBox7Click(Sender: TObject); begin with sender as Tcheckbox do begin checkbox7.tag:=6; if checked then dbnavigator.visiblebuttons:=dbnavigator.visiblebuttons visiblebuttonarray[tag] else dbnavigator.visiblebuttons:=dbnavigator.visiblebuttons - visiblebuttonarray[tag]; end; end; procedure TForm2.CheckBox8Click(Sender: TObject); begin with sender as Tcheckbox do begin checkbox8.tag:=7; if checked then dbnavigator.visiblebuttons:=dbnavigator.visiblebuttons visiblebuttonarray[tag] else dbnavigator.visiblebuttons:=dbnavigator.visiblebuttons - visiblebuttonarray[tag]; end; end; procedure TForm2.CheckBox9Click(Sender: TObject); begin with sender as Tcheckbox do begin checkbox9.tag:=8; if checked then dbnavigator.visiblebuttons:=dbnavigator.visiblebuttons visiblebuttonarray[tag] else dbnavigator.visiblebuttons:=dbnavigator.visiblebuttons - visiblebuttonarray[tag]; end; end; procedure TForm2.CheckBox10Click(Sender: TObject); begin with sender as Tcheckbox do begin checkbox10.tag:=9; if checked then dbnavigator.visiblebuttons:=dbnavigator.visiblebuttons visiblebuttonarray[tag] else dbnavigator.visiblebuttons:=dbnavigator.visiblebuttons - visiblebuttonarray[tag]; end; end;

同學您是哪幾行不明白？ 是有關 Set 型態的問題嗎？那可參考: http://delphi.ktop.com.tw/topic.php?topic_id=52123 還有以後貼程式碼的時候, 請記得用 "插入 code" 這個按鈕 詳細參考: http://delphi.ktop.com.tw/topic.php?TOPIC_ID=7326 -- Well be all right. If you dont like uphill battles, you dont like living.
