看了版上有關 USB 的讀取及使用,小弟整理了一下將它寫了 一個"可用"的完整 BCB 程式,提供給任何有興趣的人參考.< >< > 1.請放TForm1,三個TButton(cmdAbout,cmdSave,smdGetUSB) TGroupBox,TSaveDialog,TSplitter,TListBox,TTreeView 各一個. 2.DisplayUSB.h //--------------------------------------------------------------------------- #ifndef UnitUSBH #define UnitUSBH //--------------------------------------------------------------------------- #include #include #include #include <Forms.hpp> #include #include #include #include #include #include "winioctl.h" #include "usbioctl.h" #include "malloc.h" #include "cfgmgr32.h" #include "vndrlist.h" #include "stdio.h" #include "SETUPAPI.H" #include "UnitAbout.h" //--------------------------------------------------------------------------- class TForm1 : public TForm { __published: // IDE-managed Components TSaveDialog *SaveDialog1;

sorry, 貼錯了,請版主刪除此篇, Thanks 寫程式與攝影一樣重要

有沒有搞錯ㄚ!!這好像是C 的程式ㄟ
