instantiate object using 'new' keyword
Hi,
I'm having a mental block - I may have once known the answer to this but for the life of me can't recall it!
I want to create a new object at run time. What I don't want to do is this:
strAString = "datObject1" ' Defined elsewhere
Select Case strAString
Case "datObject1"
Dim anObject As datObjectTemplate = new datObject1
Case "datObject2"
Dim anObject As datObjectTemplate = new datObject2
End Select
As there are lots of objects and they all inherit from datObjectTemplate. What I do want to do is something like this:
strAString = "datObject1" ' Defined elsewhere
Dim anObject As datObjectTemplate = new ???
So my question is, what can I replace ??? with to be able to determine the type of object that is created from the contents of the strAString variable and without having to test the contents of the strAString variable and write a seperate Dim line for each possibility?!! I'm open to other suggestions - I just want to avoid the select case avenue!
Thanks a lot for looking

Yes, you can do that using reflection, give me a second and I'll dig up some example
