I'm new to VB.NET, and I am translating an object model from C# to VB.NET,
and I have come across an odd problem implementing an interface.
The interface is a custom interface, IDrillDown, which declares one
read-only property with the following VB.NET signature:
Public ReadOnly Property ActiveText() As String
I have declared the interface in the class declaration, like this:
Public Class CustomerItem
Implements IDrillDown
...
End Class
Later in the class, I implement the interface by by declaring my ActiveText
property:
Public ReadOnly Property ActiveText() As String
Get
Return Me.Name
End Get
End Property
VB.NET is giving me a compile-time error, saying that the class must
implement the ActiveText property for the IDrillDown interface. Needless to
say, I am puzzled, since I have implemented the property with the signature
required by the interface.
Can anyone shed some light on this? Thanks.

You have created a method that can implement th Interface's property,
but you haven't told VB to connect to two.
Interface implementations are explicit, so you have to add the
"Implements [Interfacename].[MethodName]" clause.
It allows you to do funny things like this :
Private ReadOnly Property Message() As String _
Implements I.ActiveText
Yes, that's a Private property, implementing a Public Interface property
with a totally /different/ name (but /same/ signature, otherwise).

Hello Everyone,
I am implementing a simple interface in C# using Visual Studio .net and was
quite surprised to discover that the C# compiler does NOT complain if a
method on the interface is not implemented.
VB.net on the other hand generates a compile error if a method is not
implemented. This helps in ensuring that all interface methods are
implemented.

I have a serious problem with VB.NET and a DataTable derived class and I

works perfectly, but I can't port one statement to VB.NET and this is
crucial: re-implementing ISerializable.GetObjectData() in the DataTable
derived class so serializing the datatable derived class will call this
method and not the DataTable version (which is private, so overriding is

Hi,
I have an interface in vb 6.0. It has a property set member, which takes a
parameter by reference. When I try to implement this interface in my vb.net
project it gives me an error saying that "cannot implement property set
because there is no matching property on interface". I think .NET does not
allow parameter to be passed ByRef in property statements.
here is my property set statement in vb 6.0 interface called IName

In a typical class, do I need to indicate that it implements the IDisposable
interface and then create a Dispose method that implements the Dispose
required by the IDisposable interface or can I just make a Sub Dispose() and
the CLR will know that this is the Dispose method to call when the object
falls out of scope?
Thanks.

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
