[2.0] Textbox Question

how can i make my input to be all capital only?
and disable special character?

thank you.

Hi, try this.

Code:

---

        public Form1()
        {
            InitializeComponent();
            textBox1.KeyPress+=new KeyPressEventHandler(textBox1_KeyPress);
        }
        private void textBox1_KeyPress(object sender, KeyPressEventArgs e)
        {
            if (!(char.IsLetterOrDigit(e.KeyChar) || (Keys)e.KeyChar == Keys.Back))
            {
                e.Handled = true;
            }
            e.KeyChar = char.ToUpper(e.KeyChar);
        }

For the casing you could set the CharacterCasing property of the control to Upper instead of the default Normal.

I always recommend checking to see what members a class has before asking questions. The answers are often obvious but you have to look first. If nothing obvious presents itself, then ask.

thanks sir.
