小弟今天嘗試將之前寫的程式寫成Active X元件好方便其他程式呼叫使用，但是在新程式裡匯入之後發現元件的function裡沒我當初宣告成public的function，不知是哪裡出錯了，請各位高手指點一下吧~~~^^& 以下是部分程式碼..我就是找不到WirelessTest這個function~~ < class="code"> class TWireless_Throughput_Tool : public TActiveForm { __published: // IDE-managed Components TTimer *Timer1; TNMFTP *NMFTP1; void __fastcall Timer1Timer(TObject *Sender); void __fastcall NMFTP1PacketSent(TObject *Sender); void __fastcall NMFTP1PacketRecvd(TObject *Sender); private: // User declarations public: // User declarations __fastcall TWireless_Throughput_Tool(HWND ParentWindow); __fastcall TWireless_Throughput_Tool(TComponent* AOwner): TActiveForm(AOwner) {}; BOOL __fastcall WirelessTest(AnsiString type,AnsiString IP,AnsiString UserID,AnsiString Passwd,double *value); };
