void SetAt( int nIndex, CObject* newElement );
nIndex
An integer index that is greater than or equal to 0 and less than or equal to GetUpperBound().
newElement
The object pointer to be inserted in this array. A NULL value is allowed.
Sets the array element at the specified index. SetAt will not cause the array to grow. Use SetAtGrow if you want the array to grow automatically.
You must ensure that your index value represents a valid position in the array. If it is out of bounds, then the Debug version of the library asserts.
CObArray array;
CObject* pa;
array.Add( new CAge( 21 ) ); // Element 0
array.Add( new CAge( 40 ) ); // Element 1
if( ( pa = array.GetAt( 0 ) ) != NULL )
{
array.SetAt( 0, new CAge( 30 ) ); // Replace element 0
delete pa; // Delete the original element at 0
}
#ifdef _DEBUG
afxDump.SetDepth( 1 );
afxDump << "SetAt example: " << &array << "\\n";
#endif
The results from this program are as follows:
SetAt example: A CObArray with 2 elements
[0] = a CAge at $47E0 30
[1] = a CAge at $47A0 40
