IOleControlSite::TranslateAccelerator method (ocidl.h)

  • Article

Passes a keystroke to the control site for processing.

Syntax

HRESULT TranslateAccelerator(
  [in] MSG   *pMsg,
  [in] DWORD grfModifiers
);

Parameters

[in] pMsg

A pointer to the MSG structure describing the keystroke to be processed.

[in] grfModifiers

Flags describing the state of the Control, Alt, and Shift keys. The value of the flag can be any valid KEYMODIFIERS enumeration values.

Return value

This method can return the following values.

Return code Description
S_OK
 The container processed the message.
S_FALSE
 The container did not process the message. This value must also be returned in all other error cases besides E_NOTIMPL.
E_NOTIMPL
 The container does not implement accelerator support.

Remarks

This method is called by a control that can be UI-active. In such cases, a control can process all keystrokes first through IOleInPlaceActiveObject::TranslateAccelerator, according to normal OLE Compound Document rules. Inside that method, the control can give the container certain messages to process first by calling IOleControlSite::TranslateAccelerator and using the return value to determine if any processing took place. Otherwise, the control always processes the message first. If the control does not use the keystroke as an accelerator, it passes the keystroke to the container through this method.
