Cannot Open Clipboard Windows 10
to copy text to the clipboard: Clipboard.Open; try Clipboard.AsText := GenerateClipboardText; finally Clipboard.Close; end; Seemingly at random I get "Cannot open clipboard: Access Denied" errors. I'm guessing that these errors are caused by other application locking the clipboard, but I never seem to be doing anything with other applications that should cause the locks.

Expect your code to fail by adding an exception handler. Then add some retry code, i.e. retry to set the text three times, perhaps with exponential backoff, before throwing your own error. I'd recommend the second solution, because it'd be the more Delphi-like approach and
