You cannot "call" the Text property. You have to assign it a string like this:

textBox4.Text = User.GenerateUserID.ToString();

textBox5.Text = User.GenerateUsername(Name.Text, MI.Text, Lastname.Text);

There is an AppendText() method that may have confused you, if you saw that in an example. Like the name suggests, it simply appends more text to the end of whatever's already in the TextBox:

textBox4.AppendText(User.GenerateUserID.ToString());

TextBox.Text is a property, its not a method. You need to assign value to the property.

textBox4.Text = User.GenerateUserID; //assuming its string or call User.GetUserID.ToString();

If User.GetUserID is a method then you need to call it like:

textBox4.Text = User.GenerateUserID();

If the returned value is not string, then you can call ToString on it like:

textBox4.Text = User.GenerateUserID().ToString(); //check for null before calling
                                                  //ToString

Do the same for:

textBox5.Text = User.GenerateUsername(Name.Text, MI.Text, Lastname.Text);
