Ok, so sorry, it was clear in my head...
Thanks for you rapid answer.
I created a userControl in Visual Studio(C#).
I inserted it in Access, in a form.
When I run my userControl in a Windows form(Visual Studio), ctrl-c, etc works fine, for all fields(events are trapped by each field).
When I ran it in Access, there was no access to the context menu when I clicked in fields. I created one with copy/cut/paste options in my userControl and use Clipboard to get/set the selection. It works fine...
But when I click ctrl-c/ctrl-v in any control of my userControl, nothing happend. I have read that keys are trapped by Access form.
I would like to know if there is a way to prevent keys to be trapped by Access...
I hope you'll understand my problem now...
