Problem when form is dynamically added in a tab page

Question

Following is the requirement:
=> I placed a button on a tabPage of tabControl.
=> On click of a button,
1. I created a Control object.
2. I created a Form object.
3. Initialize the Form Object.
4. Initialize the Control object and add it under the Form Object.
5. Initialize the TextBox object and add it under Control. (Keep some multiline text in the textBox and make it Multiline)
6. Set form.TopLevel = False
7. form.Show
8. form.Parent = TabPage.
=> When i run the above application/form, the focusing works wierdly in the textBox. I am not able to guess what the issue is.
Any help will be appriciated. :)

I don't know what initializing a control object and adding it under a formm object means. Or what initializing a textbox and adding it under control means.
Rather than setting a Forms parent as a tabpage somehow set the Form so toplevel = false and add the Form to a tab pages controls.
Even this is a poor way to do business. There's also such a thing as
MDI Forms. Although if you want controls on a Form then why not use controls with it? What would be a reason for creating separate Forms to place inside of tabpages? It sounds not well thought out design wise.
