Re: Late Binding .....

Armin,
Thanks for your link, but for custom binding methods required add referance
from dll.
<Imports Simple_Type.Sim ple_Type>
I dont want to add referance from created object dll.
Can I use Createobject() method like a vbscript codes;

dim o as object
SET o=CreateObject( "MyDll.dll","My Class")
call o.TestMethod()

Thank for your helps...

Maybe I didn't understand you correctly. You wrote a VB.Net dll. It is not a
COM dll. In a client application, you want to create objects from classes in
the dll, right? Using the methods described in the topics from the link, you
are able to do it without using "Imports" or Createobject. Much can be said
about it but I only mention System.Reflecti on.Assembly.Loa d and
System.Type.Inv okeMember.

The CreateObject() function works only with COM libraries. Therefore,
it seems you'd need to have your original .Net MyDll.dll registered in
the COM framework, first.

You need to mark the relevant class (in your case, "MyClass", although
this is a reserved name, I suppose you only used it as an example), I
was saying, you need to mark the relevant class as both "COM class" and
"COM visible" -- select the class in the project/solution explorer and
these options will become available.

Then you need to enable the "Make Assembly COM visible flag": open the
project properties and click the "Assembly Information..." button in
the Applcation tab.

Finaly, after the dll is compiled, you must register it in the COM
framework. To this, use the regasm application (I guess you can
download it with the .Net SDK):

regasm /codebase "your dll path"

Finally, inside your client application you'd use (notice that I don't
have VB.Classic installed here, so I can't confirm the syntax):

dim o as object

Set o=CreateObject( "MyDll.dll.MyCl ass")

call o.TestMethod()

HTH.

Re: Late Binding .....

Hi,
Actualy I want to write vb script in my code, for example;
'----------------------------------
Public Class TestClass
Public Sub HelloWorld()
MsgBox("Hello World")
End Sub
End Class
'----------------------------------
Compile this code and create Test.Dll
And then, create New Application Test.exe and not to add referance Test.Dll.
'----------------------------------
Private Sub Button1_Click(B yVal sender As System.Object, ByVal e As System.EventArg s) Handles Button1.Click
Dim oTest As Object
oTest = CreateObject("T est.TestClass")
oTest.HelloWorl d()
End Sub
'----------------------------------

In VB6 Test.dll compiled automaticly register and Latebind in Dll name (Test.dll) and public class (TestClass), but I think so VB.NET dll not registered in registery so how can I do this case, I want to run my code like script.

Thanks for helps again,

Hakan

There is nothing more I can add to what I've already said, sorry. The topics
in the documentation desribe in detail how to do it.
