2. If you really do need to add objects to a form in you code, you should look at the code that VS produces when using the form designer to get a feel for how it works. Instead of declaring the objects that appear on your form in the method where you're creating them like this:
TextBox textboxUsername = new TextBox();
You will declare the object variables at the top of the class definition for your form like this:
Private TextBox textboxUsername;
This will make the object available throughout your form code.
Then, in your method, you'll initialize them like this:
textboxUsername = new TextBox();
If this is still confusing, you probably need to take a C# class to get the basics down.
