Parameter

Description

[in]

UInt32

State

An value generated by OR'ing the KbdState enum constant values.  These are the values that can be returned by Datalogic.API.Device.KeybdGetKeyInputState.

State key down flags are ignored.

[returns]

Boolean

Returns TRUE if the state was successfully set, otherwise returns FALSE.

[on error]
