小弟最近自學了6個禮拜~打算寫一篇類比時鐘與數位時鐘同步顯示動作 (Timer) 
雖然數位時鐘會動~但類比時鐘就是不會動~我也不知道寫法~不知有經驗的前輩可否指教一下?? 看不懂 JAVA 沒學過^^""

Hi 你好
看了一你的程式(我沒裝BC5 沒法run)
void __fastcall TForm1::Timer2Timer(TObject *Sender)
{
Label1->Caption="現在:" Time();
}
這個timer事件只有在label秀出時間, 並沒有執行到畫圖(時針與分針的位置)的工作
應該是改成這樣就可以
void __fastcall TForm1::Timer2Timer(TObject *Sender)
{
Label1->Caption="現在:" Time();
Image1->Canvas->Rectangle(-1,-1,299,299);
Image1->Canvas->Ellipse(0,0,199,199);
Image1->Canvas->MoveTo(100,100);
Image1->Canvas->LineTo(100,0);
Image1->Canvas->MoveTo(100,100);
Image1->Canvas->LineTo(150,100);
}
當然了
時針與分針的角度要用三角函數去算xy
這裡有個JavaSCRIPT 自己參考轉換嘿
function ClockAndAssign(){
time = new Date ();
secs = time.getSeconds();
sec = -1.57 Math.PI * secs/30;
mins = time.getMinutes();
min = -1.57 Math.PI * mins/30;
hr = time.getHours();
hrs = -1.575 Math.PI * hr/6 Math.PI*parseInt(time.getMinutes())/360;
if (ie){
Od.style.top=window.document.body.scrollTop;
Of.style.top=window.document.body.scrollTop;
Oh.style.top=window.document.body.scrollTop;
Om.style.top=window.document.body.scrollTop;
Os.style.top=window.document.body.scrollTop;
}
for (i=0; i < n; i ){
var F=(ns)?document.layers['nsFace' i]:ieFace[i].style;
F.top=y[i] ClockHeight*Math.sin(-1.0471 i*Split*Math.PI/180) scrll;
F.left=x[i] ClockWidth*Math.cos(-1.0471 i*Split*Math.PI/180);
}
for (i=0; i < H.length; i ){
var HL=(ns)?document.layers['nsHours' i]:ieHours[i].style;
HL.top=y[i] HandY (i*HandHeight)*Math.sin(hrs) scrll;
HL.left=x[i] HandX (i*HandWidth)*Math.cos(hrs);
}
for (i=0; i < M.length; i ){
var ML=(ns)?document.layers['nsMinutes' i]:ieMinutes[i].style;
ML.top=y[i] HandY (i*HandHeight)*Math.sin(min) scrll;
ML.left=x[i] HandX (i*HandWidth)*Math.cos(min);
}
for (i=0; i < S.length; i ){
var SL=(ns)?document.layers['nsSeconds' i]:ieSeconds[i].style;
SL.top=y[i] HandY (i*HandHeight)*Math.sin(sec) scrll;
SL.left=x[i] HandX (i*HandWidth)*Math.cos(sec);
}
for (i=0; i < D.length; i ){
var DL=(ns)?document.layers['nsDate' i]:ieDate[i].style;
DL.top=Dy[i] ClockHeight*1.5*Math.sin(currStep i*Dsplit*Math.PI/180) scrll;
DL.left=Dx[i] ClockWidth*1.5*Math.cos(currStep i*Dsplit*Math.PI/180);
}
currStep-=step;
}
