e.Cancel = true;

}

i tried it but it didnt seem to do what i wanted it to do ...myquestion now is

i have a set button on my window and when the user clicks a wrong format ... other than the masked format i want to catch the error

say for example i have this code write..

private void setvalue_Click(object sender, EventArgs e)

string a = txBxP4.Text;

MessageBox.Show(a);

i have already set the masked text boxes to only accept input like this "##.#"

now i want to display an error message each time he enters something like 0_.0

I am sorry for the dumb questions .. i am new to programming ... any help will be very much appreciated ..

thanks
