// HTuple→VC 数据类型转换
HTuple hTuple = 1234;
int i = hTuple[0].I();                  // i=1234
long l = [0].L();                 // l=1234
long lNumber = hTuple.Num();            // lNumber=1，数据个数
double d = hTuple[0].D();               // d=1234.0000
如果hTuple里面放的不是整型变量，用hTuple[0].I()会抛出异常。应该用hTuple[0].D();  

    
hTuple = "1234";
CString strBuffer = hTuple[0].S();      // strBuffer="1234"
    
    
// VC→HTuple 数据类型转换
int ii = 1234;
double dd = 1234.1234;
CString strTemp = "Halcon";
    
HTuple hTuple2;
hTuple2[0] = ii;                        // hTuple2[0].I()=1234
hTuple2[1] = dd;                        // hTuple2[1].D()=1234.1234
hTuple2[2] = strTemp.GetBuffer();       // hTuple2[2].S()="Halcon"
    
i = hTuple2[0].I();                     // i=1234
d = hTuple2[1].D();                     // d=1234.1234
strBuffer = hTuple2[2].S();             // strBuffer="Halcon"
lNumber = hTuple2.Num();                // lNumber=3，数据个数
