HTuple和VC数据的相互转换

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
