When two buttons are pressed at same time
<p>I have a little problem. I have a form, which is my login form. Then I also have another form, which is my add user form. When I click on the login button for the login form, it needs to check if the shift and control keys are both held down on the same time. Ff both of them are not pressed, then the add user form should not open. but if they are both pressed down and the login button is clicked, it should show the form.</p>

<p>What I have:</p>

<pre><code>if (Control.ModifierKeys == (Keys.Control &amp; Keys.Shift))
{
    //Show the form
}
</code></pre>

<p>But this is not working.</p>

<p>When I have:</p>

<pre><code>if (Control.ModifierKeys == Keys.Shift)
{
    //Show the form
}
</code></pre>

<p>Then it works.</p>

<p>How can I achieve this with both buttons pressed down, control and shift?</p>
