hi, all, 
I have a .dll and .h files provided by a third-party. 
I am confuse how to import all functions from dll. 
I post the code of .h file as bellows: 
---------------DTAPI.h----------------- 
#define DTAPI_API __declspec(dllexport) 
typedef unsigned long  DTAPI_RESULT; 
class DTAPI_API  DtDevice { 
public: 
DTAPI_RESULT  AttachToType(int TypeNumber, int DeviceNo=0); 
 // Constructor, destructor 
public: 
 DtDevice(); 
 virtual ~DtDevice(); 
}; 
------------------------------------- 
how to call function "AttachToType()" from dll in LabView? 
 :worship:  thank you.
