possible Button and KeyPress conflict

Question

Hi

I'm trying to design a form in c# for PocketPC 2003. All i want it to do is execute different events on a keypress or a button click.

Let say i have a blank form, if you press A, B or C it closes the form (this bit works):

public ABC_Menu()
{
InitializeComponent();
this.KeyPress += new System.Windows.Forms.KeyPressEventHandler(this.ABC_Menu_KeyPress);
}

private void ABC_Menu_Load(object sender, EventArgs e)
{

}

private void ABC_Menu_KeyPress(object sender, System.Windows.Forms.KeyPressEventArgs e)
{

if (e.KeyChar.ToString()=="A")
{
close();
}

if(e.KeyChar.ToString()=="B")
{
close();
}

if(e.KeyChar.ToString()=="C")
{
close();
}

}

That works fine. Now if i add some buttons to the form, the buttons work but the keypress doesn't do a thing!

public ABC_Menu()
{
InitializeComponent();
this.KeyPress += new System.Windows.Forms.KeyPressEventHandler(this.ABC_Menu_KeyPress);
}

private void ABC_Menu_Load(object sender, EventArgs e)
{

}

private void ABC_Menu_KeyPress(object sender, System.Windows.Forms.KeyPressEventArgs e)
{

if (e.KeyChar.ToString()=="A")
{
close();
}

if(e.KeyChar.ToString()=="B")
{
close();
}

if(e.KeyChar.ToString()=="C")
{
close();
}

}

private void button_a_Click(object sender, EventArgs e)
{
close();
}

private void button_b_Click(object sender, EventArgs e)
{
close();
}

private void button_b_Click(object sender, EventArgs e)
{
close();
}

Can anyone explain why the keypresses aren't working but the buttons are?

Any helps is much appreciated.
