COleSafeArray::Create
Allocates and initializes the data for the array.
void Create(
VARTYPE vtSrc,
DWORD dwDims,
DWORD* rgElements
);
void Create(
VARTYPE vtSrc,
DWORD dwDims,
SAFEARRAYBOUND* rgsabounds
);
Parameters
vtSrc
The base type of the array (that is, the VARTYPE of each element of the array). The VARTYPE is restricted to a subset of the variant types. Neither the VT_ARRAY nor the VT_BYREF flag can be set. VT_EMPTY and VT_NULL are not valid base types for the array. All other types are legal.dwDims
Number of dimensions in the array. This can be changed after the array is created with Redim.rgElements
Pointer to an array of the number of elements for each dimension in the array.rgsabounds
Pointer to a vector of bounds (one for each dimension) to allocate for the array.
Remarks
This function will clear the current array data if necessary. On error, the function throws a CMemoryException.
Example
COleSafeArray saMatrix;
DWORD numElements[] = {10, 5};
// creates a 2 dimensional safearray of type VT_I2
// with size 10x5 elements, with all indices starting at 0(default)
saMatrix.Create(VT_I2, 2, numElements);
ASSERT(saMatrix.GetDim() == 2);
COleSafeArray saVector;
SAFEARRAYBOUND rgsabounds[] = { {5, 2} };
// creates a 1 dimensional safearray of type VT_I1
// with size 5 elements, with the index starting at 2
saVector.Create(VT_I1, 1, rgsabounds);
ASSERT(saVector.GetDim() == 1);
