DLL to call a VB function

[robert201]

Hello,

VS 2008

I have created a C++ smart device DLL and added it to my project.

From my VB program I can call the functions successfully in the DLL. Using the code below

<DllImportAttribute("WIN32SmartDLL.dll")> _ 
Private Shared Function AddNumbers(ByVal a As Integer, ByVal b As Integer) As Integer 
End Function 

Private Sub Form1_Load(ByVal sender As Object, ByVal e As EventArgs) 
    Dim answer As Integer = AddNumbers(25, 25) 
    
End Sub

However, I need to be able to get the DLL to get information from the VB program.

Many thanks for any advice on this,

Steve

I assume you mean that you have to pass some sort of argument to your DLL. Can you explain in more detail?
