Question

I have no idea on how to cast an object that type was ‘Object’ to a user defined class type.

I have a private instance variable:

Private studyType as Object

What i need to do is to instantiate this object from an event handling method. And no, not to instance new Object().

Basically it would look like this:

studyType = new VCEOnly()

However, I am only allowed to use the Object class subs and functions as the type was defined as Object. So i need to cast it to VCEOnly class type so i can access its subs and functions.

Basically, studyType needs to be casted from Object to VCEOnly. I am not allowed to pre-define studyType as VCEOnly when declared.

Answer 1

you can also use:

dim studyType as Object = new VCEOnly()    

...

dim studyTypeVCE as VCEOnly = nothing
if trycast(studytype,VCEOnly) IsNot Nothing then
   studyTypeVCE = DirectCast(studytype,VCEOnly)
   '... do your thing
end if

the if statement checks if the object can be casted to the wanted type and if so variable of type VCEOnly will be filled in with a cast of studytype.
