Returns the number of dimensions in the COleSafeArray object.
DWORD GetDim( );
Return Value
The number of dimensions in the safe array.
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);
