This is simple but I'm not sure how to do it:
The idea is to make a textbox inside a form in which if I enter a number this appears as '?' in the textbox.
My idea is to do it with the KeyPress event:
private void textBox1_KeyPress(object sender, KeyPressEventArgs e)
{
if ((e.KeyChar < 48 || e.KeyChar > 59) && e.KeyChar != 8)
{
}
}
Could someone tell me what to put in the "if" for this to work?
I solved it myself, but I still leave the solution in case someone needs it:
private void textBox1_KeyPress(object sender, KeyPressEventArgs e)
{
if (e.KeyChar > 47 && e.KeyChar < 60)
{
e.KeyChar = '?';
}
}
With this they will be able to enter any character calmly, but when they enter numbers they will be replaced with '?'.
If you are working on Windows forms, you could have solved it like this:
textBox1.PasswordChar = '?';
