OleTranslateAccelerator
Called by the object application, allowing the container to translate its
accelerators pointed to by lpFrameInfo.
HRESULT OleTranslateAccelertor(
LPOLEINPLACEFRAME lpFrame,
| //Possible location to send keystrokes
| LPOLEINPLACEFRAMEINFO lpFrameInfo,
| //Accelerator table obtained from container
| LPMSG lpmsg
| //Structure containing the keystroke
| );
|
|
Parameters
lpFrame
Points to the IOleInPlaceFrame interface where the keystroke might be sent.
lpFrameInfo
Points to an OLEINPLACEFRAMEINFO structure containing the accelerator table obtained from the container.
lpmsg
Points to an MSG structure containing the keystroke.
Return Values
S_OK
Indicates the keystroke was processed.
S_FALSE
Indicates the object should continue processing this message.
E_INVALIDARG
Indicates one of the arguments is invalid.
E_UNEXPECTED
Indicates an unexpected error occurred.
Comments
While an object is UI active, it always has first chance at translating any messages received. If the object does not
want to translate the message, it calls OleTranslateAccelerator to give the container a chance. If the keyboard input matches an accelerator
found in the container-provided accelerator table, OleTranslateAccelerator passes the message and its command identifier on to the container through the IOleInPlaceFrame::TranslateAccelerator method. This method returns S_OK if the keystroke is consumed; otherwise it
returns S_FALSE.
The OleTranslateAccelerator function is intended to be called only by local server object applications
and not by in-process server objects. In the case of a local server object
application, keyboard input goes directly to the object application's message pump.
If the object does not translate the key, OleTranslateAccelerator gives the container application an opportunity to do it. In the case of an
in-process server object, the keyboard input goes directly to the container's
message pump.
Note Accelerator tables for containers should be defined so they will work
properly with object applications that do their own accelerator keystroke
translations. These tables should take the form:
"char", wID, VIRTKEY, CONTROL
This is the most common way to describe keyboard accelerators. Failure to do
so can result in keystrokes being lost or sent to the wrong object during an
in-place session.
Objects can call the IsAccelerator function to see whether the accelerator keystroke belongs to the object or
the container.

Nostalgia .Net |

.Net is powerful, but not all-powerful, so sometimes we need to use Win32 API for our .Net applications. It's simple enough with Platform Invoke if you have Win32 skill, but we do not always have time to dig the ancient documentation, declare the special types that are compatible with Win32, find the values of the Win32's constants and so on. Nostalgia .Net offers several simple-to-use classes, and components that will allow you to forget about the headache of Win32 and just use the power of Win32 in your application the same way as you use the native. Net classes. More » |
