How to create a Navision dll/ocx in Visual Studio 2005 .NET

timo · 2006-11-03

I want to create a Navision Custome Control (OCX or DLL) -> for example one dll which create a "Hello World" massagebox after starting from navision.
I use Visual Studio 2005 .NET. C# is the favorieted language.

Can someone give me a Code example or guide for the dll?

Imports System.Runtime.InteropServices
Namespace Something
<ClassInterface(ClassInterfaceType.AutoDual)> _
Public Class Starter

Public Sub SayHello()
messagebox.show('Hello world')
End Sub

End Class
End Namespace

in prpreties of solution chose "output type" - class library
in configuration prop check the "registrer for COM interop"

Now you can use method of your dll in navision

It don't work.

I can't import the dll in Navision Custom Controls. Error: OLE Control can't register

Try..

using System;
using System.Windows.Forms;
using System.Runtime.InteropServices;

namespace DynamicNav
{
    [InterfaceType(ComInterfaceType.InterfaceIsIDispatch)]
    public interface INavDefault
    {
        // Method
        void HelloWorld();
        int Add2Numbers(int a, int b);
        // Property
        DateTime MyDate { set; get; }
    }
    [ClassInterface(ClassInterfaceType.None)]
    public class NavDefault : INavDefault
    {
        public NavDefault()
        {
        }
        // Method
        public void HelloWorld()
        {
            MessageBox.Show("Hello World");
        }
        public int Add2Numbers(int a, int b)
        {
            return (a + b);
        }
        // Property
        private DateTime allocDate = DateTime.Today;
        public DateTime MyDate
        {
            set { allocDate = value; }
            get { return allocDate; }
        }
    }
}

In your AssemblyInfo.cs

[assembly: ComVisible(true)]

..let me know if it works.

..psst. you can't register dotNet components in NAV Custom Controls, use regasm instead..

@ JedrzejT: Thank you It works, afer register with regasm.exe. But not as Custom Control - as Automation Server. Whats the difference?

The other Samples i will test tomorrow - thank you all

Anyone actually able to create a .NET Assembly with events that create eventtriggers in navision when setting the automation property to WithEvents "True"?

Some sample code could be useful if you have done so in the past.
Thanks.

With help from Demiliani's posts, as referenced above, I managed to get an Automation Object compiled and working with .Net 3.5 and Visual Studio 2008. To download the full solution sample code for a Hello World example (including a fob file), go to http://adventuresindotnet.blogspot.com/ ... bject.html
