CreateInstance problem

[mayetski]

Hello!

I have this kind of code before:

Select Case iSelected
Case 1
obj = New CompanyCollection
Case 2
obj = New ApplicationHostedCollection
End Select

A certain object is created depending on the selected number. However,
I would need to put the object names into a database, so
CompanyCollection and ApplicationHostedCollection is now saved in the
DB and accessed as a string value.

Im not sure how to create an instance of an object if the object name
to be created is a string variable.

I tried this but its not working

Dim strobj As String
strobj = "NPRG.Corelib.CompanyCollection, NPRG.Corelib"
Dim s As System.Type
s = Type.GetType(strobj, True)
Dim obj As Object
obj = Activator.CreateInstance(s)

The Type.GetType returns nothing so I cant move on. Am I doing
something wrong?

Please anyone help.

Thank you very much!

No, you aren't

The only thing I can guess is that you don't have the proper classname or
assembly name. Are you sure the assembly is referenced by the project?

Karl,
Thanks for the reply. Yes the assembly is referenced by the project.

Peter,
Can you give an example of how this method is used? Thanks!
