Working out if Control button is down in MouseDown event

[JezB]

How can this be done ? There's no Keys attribute in MouseEventArgs.

Hi JezB
In MouseDown handler check the Control.ModifierKeys static property here you
can find the states of ALT, CTRL and SHIFT keys.

I'll answer it myself ...

(Control.ModifierKeys & Keys.Control) != 0

You mean something like,
if ((ModifierKeys & Keys.Control) == Keys.Control) //check if Ctrl key was
pressed, note bitwise &

cheers!!

System.Windows.Forms.Control has a static 'ModifierKeys' property you can
access:

e.g.

using System.Windows.Forms;

....
if ( Control.ModifierKeys == Keys.Control )
{
// CTRL key was pressed (and no other modifier)
}
....

n!

Use the static ModifierKeys property of the Control class:

if (Control.ModifierKeys == Keys.Control)
{
// then the Ctrl key is down.
}

Typical !! Loads of people answer when you find the answer yourself - when
you are really stuck no-one gives a solution !! hehe

Use the static ModifierKeys property of the Control class:

if (Control.ModifierKeys == Keys.Control)
{
// then the Ctrl key is down.
}

If you want to check if the control key is down even when other modifier
keys are down, use this code:

\\\
If Control.ModifierKeys And Keys.Control Then
...
End If
