Thanks Rolf
Another Question. Below is the .h file
#ifndef _MPUSBAPI_H_
#define _MPUSBAPI_H_
#define MPUSB_FAIL 0
#define MPUSB_SUCCESS 1
#define MP_WRITE 0
#define MP_READ 1
// MAX_NUM_MPUSB_DEV is an abstract limitation.
// It is very unlikely that a computer system will have more
// then 127 USB devices attached to it. (single or multiple USB hosts)
#define MAX_NUM_MPUSB_DEV 127
DWORD (*MPUSBGetDLLVersion)(void);
DWORD (*MPUSBGetDeviceCount)(PCHAR pVID_PID);
HANDLE (*MPUSBOpen)(DWORD instance, // Input
PCHAR pVID_PID, // Input
PCHAR pEP, // Input
DWORD dwDir, // Input
DWORD dwReserved); // Input <Future Use>
DWORD (*MPUSBRead)(HANDLE handle, // Input
PVOID pData, // Output
DWORD dwLen, // Input
PDWORD pLength, // Output
DWORD dwMilliseconds); // Input
DWORD (*MPUSBWrite)(HANDLE handle, // Input
PVOID pData, // Input
DWORD dwLen, // Input
PDWORD pLength, // Output
DWORD dwMilliseconds); // Input
DWORD (*MPUSBReadInt)(HANDLE handle, // Input
PVOID pData, // Output

BOOL (*MPUSBClose)(HANDLE handle);
#endif
Labview does not seem to understand PVOID,DWORD,PWORD, and BOOL datatypes. I beleive these are DELPHI datatypes. What would you recommend me using for Labview recognized datatypes instead? also to I need to define my variable name as weill i.e. #define Data void
Thanks for the help
