Client Num Lock Key Is Not Turned On by Keybd_event Function

ID: Q187140

The information in this article applies to:

Microsoft Windows NT Server version 4.0, Terminal Server Edition

SYMPTOMS

When you run a program that calls the Keybd_event() function and does Keydown and Keyup for Vk_Numlock, the Num Lock key on keyboard is not turned on.

CAUSE

This function works on Microsoft Windows NT-based computers, but not Microsoft Windows 9x-based computers. Windows 9x does not handle the Num Lock key correctly using this function. However the Caps Lock works without any problem.

STATUS

This behavior is by design.
