How can you use the mouse to commit fraud?

Hi Rob
Lockout of the mouse means operator can only use keyboard in a specific way.
We are always concerned that the use of "Fraudulent Mouse" may start a world
wide slippery slide. Hence "Ban the Mouse"

I don't see where that was an answer to my question.

SetCapture - WinAPI routine.

I find SetCapture(Application.handle); disables the mouse well enough.

When I want to re-enable the mouse I first do
Application.Processmessages;
- so any clicks etc in the queue get eaten, then
ReleaseCapture;

... but if your app is multithreaded, you may have to use a different handle
to catch the mouse, or even create a window just for that purpose.

Can you simply remove any mouse events from the objects in the Till section?

Rob- use of a mouse within the Till section, COULD allow the operator to
manipulate the entries made and possibly edit them somehow. It hasn't
happened as yet, but I need to make the thing totally free from any possible
interference. I come from an old style background.. I worked for NCR in its
hay days - we always attempted to keep any chance of fraud away from the
user. (For their own good). I hope that satisfies your question.

It hasn't happened yet because it doesn't really make any sense that it
could. If there is some editable control the user should not be able to
change, make it read-only. The mouse cannot undo that in any way. In this
sense the mouse is just an alternative to using the tab key. It can do
nothing on its own unless your application specifically allows it, and you
certainly cannot enter keystrokes with it. The closest it can come to that
is if you *enable* drag and drop so a user can drag existing text from one
place to another, but drag and drop has to be explicitly enabled and handled
by the application.
