Any idea how to get this API to work?

[codercode]

Private Declare Function AccessibleChildren Lib "oleacc" (ByVal
paccContainer As IAccessible, _
ByVal iChildStart As Integer, _
ByVal cChildren As Integer, _
ByVal rgvarChildren() As Object, _
ByVal pcObtained As Integer) As UInteger

Dim iTMP As Accessibility.IAccessible
Dim lngTMP2 As Integer
iTMP = lngTMP
Dim lngCount As Integer
lngCount = iTMP.accChildCount
Dim Children(lngCount - 1) As Object

Call AccessibleChildren(iTMP, 0, (lngCount - 1), Children(0), lngTMP2)

I can't get the 'rgvarChildren' parameter correct.

My code's translated from the following C# code:

[DllImport("Oleacc.dll")]
public static extern int AccessibleChildren(
Accessibility.IAccessible paccContainer,
int iChildStart,
int cChildren,
[Out] object[] rgvarChildren,
out int pcObtained);

int _ChildCount = IACurrent.accChildCount;
object[] _Children = new object[_ChildCount];
int _out;

AccessibleChildren(IACurrent,0,_ChildCount-1,_Children,out _out);

It doesn't work on VB 2005. An empty Children is returned.
However, it does work on VB6 by declaring Children as a Variant. Any
ideas?

Thanks in advance

I will just assume that you posted this to the wrong group.

int _ChildCount = IACurrent.accChildCount;

An underscore followed by an uppercase character is reserved to the
implementation.

The code you showed is not compilable.
