Ruby WIN32OLE_VARIANT[i,j,...] =用法及代码示例

Set WIN32OLE_VARIANT 对象(OLE 数组)的元素到 val。此方法仅在 WIN32OLE_VARIANT 对象的变体类型为VT_ARRAY 时可用。

评论：

The all indices should be 0 or natural number and
lower than or equal to max indices.
(This point is different with Ruby Array indices.)

obj = WIN32OLE_VARIANT.new([[1,2,3],[4,5,6]])
obj[0,0] = 7
obj[1,0] = 8
p obj.value # => [[7,2,3], [8,5,6]]
obj[2,0] = 9 # => WIN32OLERuntimeError
obj[0, -1] = 9 # => WIN32OLERuntimeError
