Textbox Keydown

[Guest]

I have a bunch of code to get an input line from user like ensuring input is
a character rather than RightButton, and deleting past char if delete is
pressed. Can you think of an easier way to get the text that exist when the
user presses enter? Thanks.

private void m_textbox_KeyDown(object sender, KeyEventArgs e)
{
if (M_reading)
{
if (e.KeyCode == Keys.Enter)
{
M_reading = false;
mre.Set();
}
else
{
string key = e.KeyCode.ToString();
if (key.Length == 1 || e.KeyCode == Keys.Space) etc.
etc....
M_str += e.KeyCode.ToString();
}
}
}

Hi denton,

I have a feeling you are trying to reinvent the wheel.

I assume you are using a textbox, so if your goal is to have the user
press a character key, you can use the KeyPress event to check if
Char.IsLetter(e.KeyChar), if so, you got a character key, if not, you can
set e.Handled to true to prevent any number of special symbols to ever
reach the TextBox.

It is not clear to me what you are trying to do with this code so if you
can explain it (pseudocode) I might be able to help you.
