Returns the lower bound for any dimension of a COleSafeArray object.
void GetLBound(
DWORD dwDim,
long* pLBound
);
Parameters
dwDim
The array dimension for which to get the lower bound.pLBound
Pointer to the location to return the lower bound.
Remarks
On error, the function throws a COleException.
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);
long lLBound;
//get lower bound for 1st dimension
saMatrix.GetLBound(1, &lLBound);
ASSERT(lLBound == 0);
//get lower for 2nd dimension
saMatrix.GetLBound(2, &lLBound);
ASSERT(lLBound == 0);
COleSafeArray saVector;
SAFEARRAYBOUND rgsabounds[] = { {5, 1} };
// creates a 1 dimensional safearray of type VT_I1
// with size 5 elements, with the index starting at 1
saVector.Create(VT_I1, 1, rgsabounds);
//get lower bound for 1st dimension
saVector.GetLBound(1, &lLBound);
ASSERT(lLBound == 1);
