Hello!
I'm reading a book which mentioned about this AcceptButton property for a
form which seems quite easy so I try to figure out how it works but I have
run into some small problems.
I have this small easy program below which show two buttons called button1
and button2.
In this program when the Enter key is clicked event handler for button1 is
called.
I want to change that I want insted the event handler for button2 to be
called when the
Enter key is clicked.
So I tried with changing this row
form1.AcceptBut ton = button1;
with this row
form1.AcceptBut ton = button2;
but event handler for button1 is still called when the Enter key is clicked
I can't understand why?
Can somebody explain why not the event handler for button2 is called when I
haved said
that button2 should be used for AcceptButton in the form.
//Start code
//*************
using System;
using System.Windows. Forms;
using System.Drawing;
public class frmApp : Form
{
public void CreateMyForm()
{
Form form1 = new Form();
Button button1 = new Button ();
Button button2 = new Button ();
button1.Text = "button1";
button1.Locatio n = new Point (10, 10);
button2.Text = "button2";
button2.Locatio n = new Point (10,50);
// Set the caption bar text of the form.
form1.Text = "My Dialog Box";
// Display a help button on the form.
form1.HelpButto n = true;
// Define the border style of the form to a dialog box.
form1.FormBorde rStyle = FormBorderStyle .FixedDialog;
// Set the MaximizeBox to false to remove the maximize box.
form1.MaximizeB ox = false;
// Set the MinimizeBox to false to remove the minimize box.
form1.MinimizeB ox = false;
// Set the accept button of the form to button2.
form1.AcceptBut ton = button2;
// Set the start position of the form to the center of the screen.
form1.StartPosi tion = FormStartPositi on.CenterScreen ;
button1.Click +=new EventHandler(bu tton1_Click);
button2.Click +=new EventHandler(bu tton2_Click);
// Add button1 to the form.
form1.Controls. Add(button1);
// Add button2 to the form.
form1.Controls. Add(button2);
// Display the form as a modal dialog box.
form1.ShowDialo g();
}
[STAThread]
static void Main(string[] args)
{
frmApp myForm = new frmApp();
myForm.CreateMy Form();
}
private void button1_Click(o bject sender, EventArgs e)
{
int tal = 0;
tal=9;
}
private void button2_Click(o bject sender, EventArgs e)
{
int tal = 0;
tal=9;
}
}
//Tony 1 4781
Tony,
So I tried with changing this row
form1.AcceptBut ton = button1;
with this row
form1.AcceptBut ton = button2;
but event handler for button1 is still called when the Enter key is
clicked
You are in fact able to set the AcceptButton property of a form at runtime
without problems, but here the problem is that you have only buttons on your
form.
Wwhen you move the focus to a button (say, by pressing the Tab key), the
Enter key will execute that button. But if you are focused on, say, a
textbox, then Enter key will execute the default button, i.e. that button
which was set with the AcceptButton property.
To make your code work properly, try adding a textbox to your dialog box.
That should solve the issue.

Ok, my situation is like this.
I have a form with a few text boxes each with a 'validating' event, OK

properties all set.
Situation 1: (works fine)
If the user enters invalid text in a text box, presses Enter in the
text box, the validation displays a msgbox. They now correct the text,
press Enter in the text box, it validates correctly this time and the

I have login form used with ShowDialog(). I have the AcceptButton

I have noticed that if a user closes a form via pressing return (either
while the OK button has focus or if AcceptButton is set to OK for the form)
then the "ENTER" keypress event fires ON THE CALLING FORM! This is very bad
for me, because in my application, Form1 responds to an ENTER keypress by
calling Form2. If the user closes Form2 via an ENTER, then Form1 just
reopens it again, kind of trapping the user in Form2 (they can still close...

Hello all.
I'm trying to figure out exactly what is going on here. I'm getting
different results on different forms, and it's driving me nuts.
For example, I have a form called FormFinish. It's AcceptButton is set
to btnExport and the CancelButton is set to btnCancel.
btnExport on FormFinish has no event code whatsoever (not even for
click.) When the user either clicks the button or presses enter on the

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
