How to disable WM_KEYDOWN repeat event for Shift/Ctrl/Alt key?

I have an Windows application treats Windows key events.
The application conveys the Windows Message.
When I hold down the Shift key, WM_KEYDOWN message occurs repeatedly.

I want to convey just one WM_KEYDOWN message, even though the Shift key is holding down.
Would you please let me know how to resolve this issue?

You can't. Inspect bit 30 of lParam to see if the message is a transition from up to down, or a repeat of down.
