// Make sure that you specify the exact path.

#import "d:\project1.dll"  no_namespace

void main()
{
BSTR bstrDesc;
      try
{
CoInitialize(NULL);
      // Declare the Interface Pointer for your Visual Basic object. here,
      // _Class1Ptr is the Smart pointer wrapper class representing the
      // default interface of the Visual Basic object.

      _Class1Ptr ptr;
      // Create an instance of your Visual Basic object, here
      // __uuidof(Class1) gets the CLSID of your Visual Basic object.

      ptr.CreateInstance(__uuidof(Class1));
      double jiaodu =ptr->readGAM60Value("2330300D"
