Consuming Web Service from Access VBA (Type MisMatch Error)

    I am attempting to call a web service from Access 2003 (using the built-in
    web services reference tool). The web service should return an array of
    integers.

    Example web method (C#)

    [WebMethod]
    public int[] GetIntArray()
    {
    int[] a = new int[5];
    for (int i = 0; i < 5; i++)
    a = i * 10;
    return a;
    }

    However at the client side (Access VBA) I am getting the Type Mismatch
    error.
    This is the function (auto-generated by the web services reference tool ) in
    VBA that gives the error.

    Public Function wsm_GetIntArray() As Variant
    'Error Trap
    On Error GoTo wsm_GetIntArrayTrap

    wsm_GetIntArray = sc_GuidelinesService.GetIntArray()

    Exit Function
    wsm_GetIntArrayTrap:
    GuidelinesServiceErrorHandler "wsm_GetIntArray"
    End Function

    When i call my web method from a c# client, it works Ok.

    Any suggestion how how to fix this is welcome?

    Kind of funny you post your c# code. And, you even post the code generated
    by the VBA web add-in.

    However, you forget to post your few lines of code that fails? (am I missing
    something here???).

    Anyway.....

    What does the few lines of code that calls the GetIntArray in VBA look like?
    Notice that the "type" returned for that function is a variant. So, while it
    is called GetIntArrary, perhaps the variant type is still string, or even a
    "long" data type....
