Extra pixels on bottom and right sides of a bitmap image

Question

Hi,
I have designed a SDI application to display a bitmap image(1024x768). In the bottom and right sides of the displayed bitmap image there is a row and column of white pixels which are not there in the original bitmap image(I have checked this in paint). I have no clue where it is coming from. To be complete, the image is displayed in a view object derived from CSrollview.
The scroll size is set as:

C#

void CCreateGratingsView::OnInitialUpdate()
{
    CScrollView::OnInitialUpdate();
    SetScrollSizes (MM_TEXT, sizeTotal);
}

Please help. Thanks in advance,
-Danny

I've no idea but it isn't something daft where a rectangle is sized have a top left of (0,0) and a bottom right of (1024, 768) rather than a width of 1024 and height of 768 as the former would give you a bonus pixel. Without more of your code it is difficult to tell, but that sort of thing has caught me before.

That's what I just thought too. If it is exactly one row and one column then it sounds like the usual off by one error here! :)
