高手请教啊!!!
如何将DLL中引用函数(C语言格式)转为VB定义格式?
例如:
typedef struct _DRIVER_INFO_OK
{
char ModalNumber[40];
char SerialNumber[20];
char ControlNum[8];
DWORD DriveType;
DWORD Cylinders;
DWORD Heads;
DWORD Sectors;
} DRIVER_INFO_OK, *PDRIVE_INFO_OK;

int ReadPhysicalDriveInNT(const int idrive,PDRIVE_INFO_OK buf,int buflen)
其中,buf变量是指针.

上面的定义在VB中如何引用啊!!!

supergreenbean(超级绿豆) 回答应该是对的。
DLL 与 VB 数据类型对应表
类型 C 语言中的声明 VB 中的声明
8 位数值参数 char chMyChar ByVal chMyChar As Byte
BYTE chMyByte ByVal chMyByte As Byte
16 位数值参数 short nMyShort ByVal nMyShort As Integer
WORD wMyWord ByVal wMyWord As Integer
32 位数值参数 int nMyInt ByVal nMyInt As Long
UINT wMyUint ByVal nMyUint As Long
BOOL bMyBool ByVal nMyBool As Long
DWORD dwMyDWord ByVal dwMyDWord As Long
LONG lMyLong ByVal lMyLong As Long
浮点数 float MyFloat ByVal MyFloat As Single
double MyDouble ByVal MyDouble As Double
变体 VARIANT MyVar ByVal MyVar As VARIANT
VARIANTARG MyVar ByVal MyVar As VARIANT
句柄 HWND hWnd ByVal hWnd As Long
HPEN hPen ByVal hPen As Long
HGLOBAL hglbl ByVal hglbl As Long

Public Type DRIVER_INFO_OK
ModalNumber(39) As Byte
SerialNumber(19) As Byte
ControlNum(7) As Byte
DriveType As Long
Cylinders As Long
Heads As Long
Sectors As Long
End Type

Public Declare ReadPhysicalDriveInNT Lib "xx.dll" (ByVal idrive As Long ,buf As DRIVE_INFO_OK,ByVal buflen As Long) As Long
