I have a textBox on a form. When the user presses the Alt key and then the Print screen keys and upon the up of the
print screen key it adds a number to the textBox. That all works good. However when the application loses focus it does not
work. The number does not increment in the textBox when the user presses the Alt key and the the print screen key.
So I have some code I put together and it's doing nothing. Here it is below. If someone can give some help on this it would
be greatly appreciated.
private void TextBoxLostKeyboardFocus(object sender, System.Windows.Input.KeyboardFocusChangedEventArgs e)
int count = 0;
if (count == 0)
textBox1.Text = "0";
