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);
