Overriding Key Strokes

I need to override the Enter key for the entire form. In my Windows form,
when a user presses Enter, I want it to behave just like a Tab, except when
the focus is on a button. Here are the 2 methods I've tried:

public EstDefaults()
{
InitializeCompo nent();

KeyPress += new KeyPressEventHa ndler(EstDefaul ts_KeyPress);
}
private void EstDefaults_Key Press(object sender, KeyPressEventAr gs e)
{
if (!exit.Focused || !cancel.Focused || !Delete.Focused )
{
e.KeyChar = (char)9;
}
}
AND
public EstDefaults()
{
InitializeCompo nent();

KeyDown += new KeyEventHandler (EstDefaults_Ke yDown);
}

private void EstDefaults_Key Down(object sender, KeyEventArgs e)
{
if (!exit.Focused || !cancel.Focused || !Delete.Focused )
{
e.KeyCode = Keys.Tab;
}
}
The KeyPress does nothing, and the KeyDown won't compile because e.KeyCode
is read-only. KeyPreview is set to True at the form level.

What am I doing wrong? Thanks!

Use keypress. If the key is "enter", set e.handled to "true". That
will make the control ignore the "enter" event. Then you can use the
GetNextControl( ).Focus or SelectNextContr ol methods (not sure which) to
handle activating the next control.

Thanks, I'll try it.

If it ignores the Enter key, will it still go through the validation process?

In Python, you can override the behaviour of most operators for a class, by defining __add__, __gt__, and the other special object methods. I noticed that, although there are special methods for most operators, they are conspicuously absent for the logical "or" and "and". I'm guessing that the reason for this is that these operators short-circuit if their first operand answers the whole question? Would it be possible to allow...

Hi, I have 3 questions regarding the code below: 1) Why can't I trap the KEYDOWN while I can trap KEYUP? 2) Is it correct that I use Return True within the IF-Statement? (I've already read the documentation but it is rather hard to understand so please don't refer to it :) 3) Many examples in the newsgroups use Return MyBase.ProcessKeyPreview(m) as the last code line while I have used Return MyBase.ProcessKeyEventArgs(m)

The Object class has five non final methods namely equals, hashCode, toString, clone, and finalize. These were designed to be overridden according to specific general contracts. Other classes that make use of these methods assume that the methods obey these contracts so it is necessary to ensure that if your classes override these methods, they do so correctly. In this article I'll take a look at the equals and hashCode methods. ...
