Hi,

I downloaded your example and just compiled it with #develop (last version). The dll work correctly then I test it with b4ppc on my desctom computer. But when I try to add dll in a b4ppc project on my compact device, I get messagebox that "an error occured. NotSupportedException". Can you tell me what I do wrong.

Device: HTC Artemis, WM6

Thanks.

Hi,

Menu->"Project"->"Project Options"
Click "Compiling" tab".
At "Target Framework" combo, select "Compact Framework 1.0" or "Compact Framework 2.0".

First you should install Compact Framework SDK.

Hi. I code my DLLS in Vb.NET. If I have a class named "Const", and Const is a reserved keyword, and because this .net library is closed-source, how can I use this "Const" class? It has some unsined hexadecimal integers it returns that I need to use. If I convert these integers, they turn into signed integers and I get errors. Thanks.

Can you explain what the problem is in some more detail as I don't understand it.

Hi. I am trying to wrap a c# class from within a VB.NET library, but the class from the C# dll is named Const. It returns unsigned Hexadecimals I nee to pass to a couple of other subs/functions. The problem is that in VB.NET Const is also used to declare Constants. So how can I use this kind of conflicting class? Thanks.

If it is a C# dll I presume you have a reference to it in your project rather than using DLLImport (aka Declare). The class Const should be in its' own namespace in that dll so try referring to it as "WhateverNamespace.Const"

Hi, thanks but however when I do that, VB.NET says that Const must be used as declaring variable types and can't be a class. This C# dll I am trying to wrap is closed, but I'm making a wrapper for it in VB.NET for Basic4ppc. I guess I could try letting Basic4ppc deal with passing the Constance in the Const class to my wrapper? Thanks.

What are you using? This works for me in VS2005

C# DLL
-----------------------
namespace ClassLibrary1
{
    public class Const
    {
        public Const()
        {
        }

        public String Version
        { get { return "Const" ;}}
    }
}

-------------------
VB.NET
-------------------
Imports ClassLibrary1

Public Class Form1
    Dim Test As ClassLibrary1.Const = New ClassLibrary1.Const

    Private Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
        MsgBox(Test.Version)
    End Sub
End Class

Hi. I am having a hard time following the ScrollBar VB example for creating and raising events in a Basic4ppc library. Can someone show me a more simpler example of how I can raise events to activate in Basic4ppc maybe show an infinite loop of a counter being incremented by 1 and when it gets to 10 the loop raises an event to Basic4ppc and exits? Thanks.
