Passing Arrays to C++ DLL Functions

[MukeshMak]

Hi all,

I'm trying to get a C++ dll to fill an array that has been passed to it using VB.

I use the following code to test the function:

*******************************************************
' Declare the C++ DLL Function
Private Declare Function test Lib "test.dll" ( ByRef intArray as Integer, ByVal arraySize as Integer) as Integer
.
.
' In my function
.
.
Dim iArray()
ReDim iArray(10)

test ( iArray(0), 10 )
.
.
' print the results... etc....
*******************************************************

Now the problem is that only the element iArray(0) is actually updated by the DLL although, I have verified that all elements are changed within it.

The function within the dll has been defined as:

*******************************************************
int __stdcall test ( int * intArray, int arraySize )
*******************************************************

Also the C++ dll works fine in conjunction with C++ programs.

Appreciate it if anyone could give me a hand with this.

Thanks.

You can not pass a Variant, array or not. It wants a Integer array.

Dim iArray() As Integer
ReDim iArray(10)
' Took off the parens
test iArray(0), 10
