IOleInPlaceSite::Scroll
Tells the container to scroll the view of the object by a specified number of
pixels.
HRESULT Scroll(
SIZE scrollExtent
| //Number of pixels
| );
|
|
Parameter
scrollExtent
[in] Contains the number of pixels by which to scroll in the X and Y directions.
Return Values
S_OK
The method successfully executed the view scroll instruction.
E_INVALIDARG
An invalid argument.
E_UNEXPECTED
An unexpected error occurred.
Comments
As a result of scrolling, the object's visible rectangle can change. If that
happens, the container should give the new ClipRect to the object by calling IOleInPlaceObject::SetObjectRects. The intersection of the ClipRect and PosRect rectangles gives the new visible rectangle. See IOleInPlaceSite::GetWindowContext for a discussion of ClipRect and PosRect.
Notes to Callers
Called by an active, in-place object when it is asking the container to scroll.

.Net is powerful, but not all-powerful, so sometimes we need to use Win32 API for our .Net applications.

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 » |
