ReleaseKey method of the Msvm_Keyboard class

Hyper-V

Simulates a key release. When successful, the key will be in the up state.

Syntax


uint32 ReleaseKey(
  [in]  uint32 keyCode
);

Parameters

keyCode [in]

Type: uint32

The virtual key code of the key to release. For the list for virtual-key codes, see Virtual-Key Codes.

Return value

Type: uint32

A return value of zero indicates success. A nonzero value indicates a failure to modify the key state.

Remarks

The ReleaseKey method maps references to the VK_MENU (18), VK_CONTROL (17), and VK_SHIFT (16) to VK_LMENU (164), VK_LCONTROL (162), and VK_LSHIFT (160), respectively, because the VK_MENU, VK_CONTROL, and VK_SHIFT virtual key codes do not represent real keys on a keyboard.

Access to the Msvm_Keyboard class might be restricted by UAC Filtering. For more information, see User Account Control and WMI.
