New vs CreateObject

Actually Charles, you do not have a fully qualified ProgID in your call to CreateObject. It works when using "As New" syntax because VB has already loaded the library and knows where to find MYOBJ (asuming there is no conflict). Use the full ProgID which is:

Set MyObj = CreateObject("<ProjectName>.<ClassName>")

= )

Hi,
I developed a simple dll and registered in my system. I add in the reference
of the dll in my new VB application. I have no problem in creating instance
of the object using New operator. However, I run into error saying unable to
create ActiveX when I try to use CreateObject.

set myobj = new MYOBJ 'OK
set myobj = CreateObject("MYOBJ") 'Error

Any suggestion?

It sounds like you DLL didnt register correctly.
Options:
1. Use Regsvr32 and attempt to register the dll.
2. Use the ActiveX Control Test Container and register it that way.
3. Package into a standard setup package and install is that way.

Hope that helps,
Jean

CreateObject doesn't use project references, it has to be told where to find
it.

Set myobj = CreateObject("MyComponent.MYOBJ")

CreateObject requires "ProjectName.ClassName" as the parameter

You can't just reference the project, as CreateObject ignores your
references and looks in the registry.
