怎样传递给ocx控件一个variant数组？？是用safearray吗？
--vb如下
Sub ReFFT_Example() 'Generate an array with random numbers and compute its FFT. Const n = 256 Dim x As Variant, y As Variant, z As Variant Dim seed As Variant seed = 17 x = CWDSP1.Uniform(n, seed) //返回一variant数组,n=数组个数,CWDSP1--ocx CWDSP1.ReFFT x, y, zEnd Sub
----
可是我在vc中用_varint_t vt[100],程序却非法。
