The get_Top method retrieves the top window coordinate.
Syntax
HRESULT get_Top(
long *pTop
);
Parameters
pTop
Pointer to the top coordinate, in pixels.
Return Value
Returns an HRESULT value.
Remarks
The window has a position on the desktop. This is expressed in pixels by four coordinates (left, top, right, and bottom). Interfaces that are automated by OLE typically express this position through left, top, width, and height; this is the convention used in DirectShow. All coordinates are expressed in pixels, and changing any coordinate will update the window immediately.
Setting the left or top coordinates moves the window left or up, respectively; these coordinates have no effect on the width and height of the window. Likewise, setting the width and height does not affect the left and top coordinates.
