How to Use ProgID in VB.NET

[eli]

Hi,

simply put, I have a function that accepts a ProgID. I want to call
that function providing the ProgID of a DLL project (made in VB.NET!!!
NOT COM!). Can I do this? Do the Library projects created with VB.NET
have a ProgID?

thanks in advance. Any help will be appreciated

Yes. See the Activator.Creat eInstance() method.

They have a fully-qualified name (namespace.obje ct) that the runtime
uses to locate the proper assembly to load.

Thank you for your answer.
The name you told me about (namespace.obje ct):
1) where can I see it?
2) Can I use it as a ProgID?

thanks again

If it's your component, the namespace is something you define with the
"Namespace" statement (but becareful and check your project properties
because VB.NET adds a "Initial namespace" and that can be confusing).

Assuming the VB.NET project properties does *not* have an initial
namespace declared, here's some examples defined in code:

Namespace MyCompany
Public Class Foo
...
End Class
End Namespace

The fully qualified name of "Foo" is "MyCompany.Foo" . Another example
(showing that a namespace can contain "."):

Namespace ABC.Product.Wid gets
Public Class Bar
...
End Class
End Namespace

The fully qualified name of "Bar" is "ABC.Product.Wi dgets.Bar".

You mean to create an instance of the class by name? Yes, see
"Activator.Crea teInstance".
