Hi,

I need to pass a two dimensional array from VB.NET to a C DLL
function. The prototype for the C function is as follows:

int _stdcall myFunction (int **matrix)

I have created an array in VB as

Dim t(2,2) As Integer and initialized. Please let me know how to do
this..

Thanks

Hi,

I have created the dll and used the declare statement as

Declare Function TestArraysOfInts Lib "DemoDll.dll" ( _
ByRef myArray(,) As Integer, ByVal row As Integer) As Integer

But when I call this function it gives a null reference exception. I
need to be able to pass the array to dll and receive the changes made
by dll in VB.NET..Please help..

Thanks in Advance
