Answer 1

It's very hard to understand your question, but let's try some guessing:

You have a form, and if a user presses some specific key, you'd like to create a new TextBox and show it on your form regardless which control has currently the focus in your form.

If this statement is true, you can set Form.KeyPreview to true. And add an event handler to Form.KeyDown.

Due to the fact, that you set the preview to true you'll get every keyboard hit before it will be give further to the control that has currently the focus. So here you can check if the key that was pressed is the one you're listening for. And if yes, just call your TextBoxFactory and set the e.Handled to true to prevent that this key stroke will additionally reach the currently focused control.

I use the KeyDown event, to intercept the 'F1' key to provide my small help in a very small programm. Here is the code:

private void MainForm_KeyDown(object sender, KeyEventArgs e)

    {
        if (e.KeyCode == Keys.F1)
        {
            //Your Code here
        }
    }
