Creating DLL and use it in navision

  1. Create a new class library project named DDL Sample in Visual Studio.

  2. Add a new file called DLL Sample with the following code:

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

using System.Text.RegularExpressions;

using System.Runtime.InteropServices;

namespace DLL_Sample

{

[ClassInterface(ClassInterfaceType.AutoDual)]

[ProgId(“Class1”)]

[ComVisible(true)]

public class Class1

{

public int add(int a, int b)

{

return a + b;

}

}

}

  1. View the Properties of the project.

  2. On the Build tab set the Register for COM interop property to True (checked).

  3. Save and compile your objects.

  4. Create a new object in navision say form.

  5. Write the following code in onpush of button.

if isclear(sample) then

create(sample);

message(format(sample.add(12,12)));

Where Sample is of type automation of subtype ‘DLL_Sample’.Class1

The subtype depends on the project name and class name that you have entered.
