How to code the creation of object when the class is not known?

[Guest]

Normally, to create an object instance based on a specific class, we can do
this.

Dim someObj As Object
someObj = New Class

However,I want to create an object instance based on a variable or
something. For example, I have 3 classes: Class1, Class2, Class3. The
variable dynamicClass can be equal to any of the 3 classes

Dim someObj As Object
someObj = New dynamicClass

Thanks Armin. I hope I can understand it (reflection) since I'm new to
..net. I hope MS has a webcast to explain it.

Do you really need it? I mean, a class name in a variable. What are you
trying to accomplish?

Hi Armin,

One example is that I have 2 windows forms with the same name but in
different path. I want to create an instance of the form but the class may
be one of 2 forms depending on some conditions.
