I am using a keydown event to detect keys pressed and have several key combinations for various operations.
if (e.KeyCode == Keys.C && e.Modifiers == Keys.Control && e.Modifiers == Keys.Shift)
{
//Do work
}
else if (e.KeyCode == Keys.V && e.Modifiers == Keys.Control)
{
//Paste
}
For some reason the key combination in which I hit Ctrl + Shift + C is not working. I have re ordered them, and placed it at the top thinking it might be interference from the Ctrl + C, and even removed the Ctrl + C to see if it was causing a problem. It still does not work. I know it's probably something very simple, but can't quite grasp what it is. All of my 1 modifier + 1 key combination's work fine, as soon as I add a second modifier is when it no longer works.
Another way would be to add an invisible menu item, assign the Ctrl + Shift + C shortcut to it, and handle the event there.
Seeing as no one else mentions them, i'm just going to leave the suggestion to use KeyEventArgs.KeyData:
This should only act on specific key combinations, though the order of the modifiers don't seem to matter, the first one is always the last pressed key.
And e.Handled = true should stop it, though i don't know the specific mechanics behind it.
This is what I did for a Ctrl+Z Undo and Ctrl+Shift+Z Redo operation and it worked.
Have you tried
e.Modifiers == (Keys.Control | Keys.Shift)
?
