calling a c# dll with vb6

Question

Hi all! I'm really new to vb6 and have some knowledge of C# and would like to create a vb6 program that calls a C# dll but I've found a huge problem which is, I always get a "dll runtime error 453". I've been googling for some hours and can't find the solution for this problem... please help. thanks a lot B33bs (here's the code sample... it's just an example) Private Declare Function func Lib "C:\Documents and Settings\...\dllnewAtt.dll" () As String Private Sub Command1_Click() Dim nSpeed As String nSpeed = func() Form1.Text1.Text = nSpeed End Sub
