, for example, there are a number of type double 100, want to transfer to COleSafeArray saValues in do??
This is me to write a program const int knMaxAtOnce=1;
Int nStartIndex=19;
Int nVarIndex;
NVarIndex=1;
Double dValue;
BOOL bOK=TRUE;
Cstrings strValue;
COleSafeArray saValues;
DWORD dwElements [1].
LPTSTR pStrz;
Double * pdValue;

DwElements [0]=knMaxAtOnce;
SaValues. Create (VT_VARIANT, 1, dwElements);
SaValues. AccessData (* *) (void & amp; PdValue);
* pdValue=https://bbs.csdn.net/topics/100;
SaValues. UnaccessData ();
Mytrio. SetTable (nStartIndex nVarIndex, saValues);
In the last sentence to set breakpoints, saValues no I want to deposit 100

COleSafeArray ar; 
Ar. CreateOneDim (VT_R8 iNums, pData);

Still won't do, CreateOneDim is to create a dimension, and iNums is 100, 100 d, pData is to store the number of each dimension;

Double f=100;
COleSafeArray ar;
Ar. CreateOneDim (VT_R8, 1, & amp; F);
