How can i change the focus to be on Form1 from being on the new Form?
<p>I have a button click wich i click on and it open a new Form.</p>

<p>Then i can click on the new Form listBox and everything.</p>

<p>Now when i want to back to the Form1 and click there on the menu or a button i need to click on it twice since the control/focus was on the new opened Form.</p>

<p>What's the best way to bring back the focus/control to Form1 without clicking on it first ?</p>

<p>Maybe to use an event that if i move the mouse over Form1 area it will bring the focus/control to the Form1 ?</p>

<p>This is how im doing to open/show the new Form:</p>

<pre><code>if (toolStripComboBox2.SelectedIndex == -1 &amp;&amp; toolStripComboBox1.SelectedIndex == -1)
{
}
else
{
    Lightnings_Extractor.Lightnings_Mode lightningsmode1 = new Lightnings_Extractor.Lightnings_Mode(this);
    lightningsmode1.Show();
}
</code></pre>

<p>I want to make that even if the new Form is open without closing it im moving back to Form1 so the control/focus will be on Form1. And also if im closing/exiting the new Form so the control/focus will be on Form1 automatic without the need to click on it area first. </p>
