我的平台是BCB6+WIN XP試著用網上的資源 嘗試了以下方法 1. implib XXX.lib XXX.dll 2. impdef XXX.def XXX.dll -->implib XXX.lib XX.def 3. coff2omf In.lib Out.lib    可是依然得到Error訊息 [Linker Error] Unresolved external '__stdcall VendorCommandBulkWrite64(unsigned char, unsigned short, unsigned short, unsigned short, unsigned char *)' referenced from C:\PROGRAM FILES\BORLAND\CBUILDER6\PROJECTS\TESTSUNPLUS_1\MAIN.OBJ    程式 dlllist.H int __declspec(dllexport) __stdcall VendorCommandBulkWrite64(                 UCHAR Request,                  USHORT Index,                  USHORT Value,                  USHORT Length,                   PUCHAR Buffer                         );    main.CPP.    #include  #pragma hdrstop #include "Main.h" #include "dlllist.h" //--------------------------------------------------------------------------- #pragma package(smart_init) #pragma resource "*.dfm" TForm1 *Form1; //--------------------------------------------------------------------------- __fastcall TForm1::TForm1(TComponent* Owner) : TForm(Owner) { } //--------------------------------------------------------------------------- void __fastcall TForm1::Button1Click(TObject *Sender) { int z; UCHAR BUFFER[64]; z=VendorCommandBulkWrite64(0x24,0,0,1,&BUFFER[0]); //ShowMessage(z); } //--------------------------------------------------------------------------- 請問各位大大我還有什麼方法可以嘗試 謝謝

補上，我用tdump抓出的TXT Turbo Dump Version 5.0.16.12 Copyright (c) 1988, 2000 Inprise Corporation Display of File USB_CAM.DLL EXPORT ord:0001='?BadPixel_Dnload@@YAHPADP6AX0@Z@Z' EXPORT ord:0002='?BadPixel_DnloadEx@@YAHPADP6AX0@Z@Z' EXPORT ord:0003='?Capture_DOSFAT_DSC@@YAHXZ' 我有用tdump隨便抓個dll的TXT Turbo Dump Version 5.0.16.12 Copyright (c) 1988, 2000 Inprise Corporation Display of File IEFDM.DLL EXPORT ord:0001='DllCanUnloadNow' EXPORT ord:0002='DllGetClassObject' EXPORT ord:0003='DllRegisterServer' EXPORT ord:0004='DllUnregisterServer' 請問為何會差這麼多？ 謝謝 我該如何改我的DEF? LIBRARY USB_CAM.DLL EXPORTS ?BadPixel_Dnload@@YAHPADP6AX0@Z@Z @1 ; ?BadPixel_Dnload@@YAHPADP6AX0@Z@Z ?BadPixel_DnloadEx@@YAHPADP6AX0@Z@Z @2 ; ?BadPixel_DnloadEx@@YAHPADP6AX0@Z@Z ?Capture_DOSFAT_DSC@@YAHXZ @3 ; ?Capture_DOSFAT_DSC@@YAHXZ ?Capture_DRAM_DSC@@YAHXZ @4 ; ?Capture_DRAM_DSC@@YAHXZ 謝謝

stevenhschen 你好: 先參考以下這篇文章中的說明 (先試靜態連結，如果不行，再試動態連結) http://delphi.ktop.com.tw/topic.php?TOPIC_ID=33420 -- Enjoy Researching & Developing --

Dear RaynorPao 您好 我剛剛試過了靜態連結還是不行 動態連結能夠Build成功 但是因為我手上沒有平台（這是內嵌式平台的Driver Control) 於是我隨便亂打了個沒有的指令(ex. ABC(int,int)) 結果居然依然能夠Build成功 請問動態連結是否不會先去找是否真的有此函數 只要語法對就能Build成功？ 另外 我明天會綁上平台試試看 先謝謝您 StevenHSChen

包子大大    對不起 還是不行 可否幫我看看 我主要嘗試呼叫連接USB的一個裝置 使用 CheckBulkDriver 指令 錯誤訊息如下圖    #include  #pragma hdrstop #include "Unit1.h" //--------------------------------------------------------------------------- #pragma package(smart_init) #pragma resource "*.dfm" #define ERROR_SUCCESS 0 // The operation completed successfully. #define ERROR_INVALID_FUNCTION 1 // Incorrect function. #define ERROR_FILE_NOT_FOUND 2 // The system cannot find the file specified. #define ERROR_PATH_NOT_FOUND 3 // The system cannot find the path specified. #define ERROR_TOO_MANY_OPEN_FILES 4 // The system cannot open the file. #define ERROR_ACCESS_DENIED 5 // Access is denied. #define ERROR_INVALID_HANDLE 6 // The handle is invalid. //#define ERROR_ 7 // Reserve #define ERROR_NOT_ENOUGH_MEMORY 8 // Not enough storage is available to process this command. //#define ERROR_ 9 // Reserve //#define ERROR_ 10 // Reserve #define ERROR_FUNCTION_NOT_READY 82 // This software function is not support.
