Calling dll from TestComplete script

Hi,



I'm writing a TestComplete script to pass arguments (int) to AQ_SetStart function in dll (dll is wrriten inV C++).  Below is my C++ code for dll  functions. While executing this TestComplete script,  getting below error . And appreciate your early help.



Error

'Lib.AQ_SetStart'

Below code is used in dll



#include<windows.h>

#include"justDLL.h"



void AQ_SetStart(int a)

{

    temp =a;

}



int AQ_GetStart()

{

    return temp;

}

********************************

Below is JustDLL.h code



int temp;

extern"C"

__declspec(dllexport)

void AQ_SetStart(int);



extern"C"

__declspec(dllexport)

int AQ_GetStart();

***********************************

Below is TestComplete VBscript to call this dll and pass int values



Sub TestFunction

  Dim MyStructID, A1, Def_DLL, Lib



  MyStructID = DLL.DefineType("Mystruct", _

                            vt_i4, "First")

  Set A1 = DLL.New("Mystruct")



  A1.First = 1

 

  Set Def_DLL = DLL.DefineDLL("DD1440A_DAQ_V_1.dll")

  Set Lib = DLL.Load("C:\Users\20039895\Desktop\Test Complete_Tututorial\Custom_DLL\DD1440A_DAQ_V_1.dll")

  call Def_DLL.DefineProc ("AQ_SetStart", VT_INT)

   

  Lib.AQ_SetStart A1  

    

End Sub
