i would like to set focus on a text field, when window(form) in on top of all on the desktop.

i have experimented with this ...
        private void Form1_Resize(object sender, System.EventArgs e)
        {
            if (this.WindowState == FormWindowState.Maximized)
            {
                MessageBox.Show("Maximized");
            }
            else if (this.WindowState == FormWindowState.Minimized)
            {
                MessageBox.Show("Minimized");
            }
            if (ActiveForm == this)
            {
                MessageBox.Show("activated");
                textBox2.Focus();
            }
        }

but this code only shows ...
"MessageBox.Show("Minimized");, window.

it only detects miinimized state, not the returning to maximiz state.
i would like to know how to detect if a form application is on top.

thank u.


i'm fairly a n oob in this materiaal.

You can override the OnActivated() Method of the form.

protected override void OnActivated(EventArgs e)
{
    textBox2.Focus();
}

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

Simple solution... you misspelled it (remove the d at the end).

Regards,
Bruce
protected override void OnDeactivate(EventArgs e)
{
    Debug.WriteLine("Deactivated");
    base.OnDeactivate(e);
}
