creating objects at runtime, on the fly

[fguihen]

i have to create a number of objects. they could be forms or any object really, but i want to know is how do i create a new object when a user clicks a button? the user could click the button many times, creating many objects, and i dont want to limit the user by only declaring a set number of objects

As far as I know, all objects are created at runtime.

I don't believe there is a piece of software that can manipulate data before it is run.

 

Ok, past the sarcasm, Im going to assume 1. you know what you are talking about and 2. you don't know the type of the object you want to instantiate...

Here's an example of creating a form from scratch and adding a textbox to the form

 

       Dim frm As New Form
       frm.Name = "frmCreated"
       frm.Text = "Created Form"

       Dim tb As New TextBox
       tb.Name = "tbTest"

       frm.Controls.Add(tb)
       frm.Show()

 

Of course you can set other properties of the form and textbox such as size, location, borderstyle, etc.
