问题： 再问VC，VB混合编程，Dll的数组指针传值问题描述:
再问VC，VB混合编程，Dll的数组(指针)传值问题，如：
VC中的代码
extern "C" void _stdcall EXPORT Test(double arr[],int n,double *sum)
{
AFX_MANAGE_STATE(AfxGetStaticModuleState());
int i;
for(i=0;i<>
{
*sum+=arr[i];
}
}
VB中代码
Declare Function Test Lib "D:\在编程序\VB调MFCDLL\BasicMathLib.dll" (ByRef inputer() As Double, ByVal n As Integer, ByRef sum As Double) As Long
Private Sub Command2_Click()
Dim a(4) As Double
Dim i As Integer
For i = 0 To 4
a(i) = i
Next
Dim dsum As Double
Dim result As Long
Call Test(a, 5, dsum)
MsgBox dsum
End Sub
