檔案中'HidD_GetHidGuid()' 是win98ddk中的一個kernel Model function,不曉得在building c++ 6.0中如果需要引用kernel Model 的函數,需要設定什麼環境呢?在project/option/link中我己試過,但還是沒用,以下是編譯時產生的錯誤訊息:      [ linker Error] Unresolved external 'HidD_GetHidGuid' referenced from D:\D_TEMP\USB_BORLAND\MAIN.OBJ    以下是原始程式,我用的是Building c++ 6.0 /***------------main.cpp------------//    #include  #pragma hdrstop #include "main.h" #pragma package(smart_init) #pragma resource "*.dfm" #include "c:\98ddk\src\hid\inc\hidsdi.h" extern "C" { #include "c:\98ddk\src\hid\inc\HIDSDI.H" } TForm1 *Form1; __fastcall TForm1::TForm1(TComponent* Owner) : TForm(Owner) { GUID HidGuid; HANDLE hHidKbd = NULL; HidD_GetHidGuid(&HidGuid); } //----------main.h-----------------------------// #include #include #include #include <Forms.hpp> #include "windows.h" #include "c:\98ddk\inc\win98\setupapi.h" // VC 5 one is out of date #include #include "winioctl.h" #include "assert.h" //--------------------------------------------------------------------------- class TForm1 : public TForm { __published: // IDE-managed Components TMemo *Memo1; private: // User declarations public: // User declarations __fastcall TForm1(TComponent* Owner); }; //--------------------------------------------------------------------------- extern PACKAGE TForm1 *Form1; //--------------------------------------------------------------------------- #endif
