This should help with viewing help files in Windows Vista (as a

is essential).<br>

there a workaround to this, so I can view the e-prime basic files?

I cannot think of why might else you would crave this
knowledge. The
documention, topic Canvas, will help understanding this
code, you will
need to if it is Canvas that you wish to use<br>

<blockquote type="cite">Thank you Alphonse, for the
quick reply. More for the purpose of understanding the
code, than
anything else, why do you repeat cnvs.Copy offScreenCnvs,
myRect,
myrect (with myrect twice)? More specifically, how is this
understood by
e-prime? Also, I am guessing I do not have to include a
slideobject?<br>

both the size of the images to-be-loaded, but the
StimRect at the
(Left,Right, Top,Bottom) coordinates where the
stimulus will be
displayed. When we copy the image from the offline
canvas to the online
canvas, we will copy from StimLoadRect to
StimRect.<br>

the properties section. I
know this appears elementary, but the actual
size of the images are 424 X
283, but when running, part of the images are
cut off. When I looked at
the properties of my slide object, I had set the
width at 25% . I assumed
this was the co-ordinate location in relation to
the actual screen size.
Guessing that this was an error on my part, I
reset the width to 100%,
but that meant that when I looked at the
slideobject (with the dotted
grid), one image seemed to complete cover the
other image. How do I fit
both images, and make sure their dimensions
remain the same?<br>
