第一次練習執行緒 一直抓不到錯在哪
不知道為什麼那一行會一直出錯 導致後面沒辦法呼叫執行緒

kkkor你好
試著把標頭檔"TimerThread.h"丟到"main.h"去
//新手上路，請多包涵。

是在 main.h 中加入 #include "TimerThread.h" 嗎?
還是一樣出錯 =o="

kkkor 你好..
是喔！！還是錯誤.......真是殘念
但是我猜測你的意思，寫了一個小程式如下：參考看看
///****************main.cpp

kkkor你好
試著在TForm class下加入這各data member
class TForm1 : public TForm
{
__published: // IDE-managed Components
TMemo *Memo1;
TButton *Button1;
TButton *Button2;
TButton *Button3;
void __fastcall FormCreate(TObject *Sender);
void __fastcall Button1Click(TObject *Sender);
void __fastcall Button3Click(TObject *Sender);
void __fastcall Button2Click(TObject *Sender);
private: // User declarations
public: // User declarations
__fastcall TForm1(TComponent* Owner);
TTimerThread *TimerThread;
}; //新手上路，請多包涵。

kkkor你好 錯誤訊息已經說了，他看不懂TimerThread是什麼
所以你要在main.cpp中先宣告TTimerThread *TimerThread;

KKKor,
把true 改成 false 試試看
TimerThread = new TTimerThread(false)
