The get_Left method retrieves the current left window coordinate.
Syntax
HRESULT get_Left(
long *pLeft
);
Parameters
pLeft
Pointer to the left coordinate, in pixels.
Return Value
Returns an HRESULT value.
Remarks
The window has a position on the desktop. This position 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 and up, respectively; these coordinates have no effect on the width and height of the window. Likewise, setting the width and height have no effect on the left and top coordinates.
