Hi,

I am having problems in Visual Basic 4.0 on a 256 color display.  The colors
are getting messed up by the system somehow.  Here is the situation:

- one form has a 256 color bitmap (BMP) (61 unique)
- in this form we have (at the same time) a picturebox control that
  displays an AVI animation using the MCI control

The Problem:
Once the animation starts to play the first frame of the animation, the
colors in the background picture AND the picturebox both get messed up.  For
all the other frames, the colors appear normal until it reaches the end, and
then the colors get messed up again on the last frame.

The total unique colors we have in the form is 159.. so why is Windows
messing them up?

Any help or tips would be very appreciated!  Thanks..

Marc, you probably have 2 different palettes, one for the graphic and one
for the avi file.  Try using the Indeo palette for each of them.  This will
make sure that both files have the same palette (with all the required
windows colors).  

Hope this helps

The .pal's or .dib's of these codec's palettes are available from Intel
or Radius, or on the major online services.

Alternately, you could render the videos down to 256 color using rle
encoding, or by using MSVideo1 codec and applying the same palette as
the surrounding graphics.

If each is creating it's own palette, remapping colours in the process,
this will happen.  There is no workaround I'm aware of....it's a 256-colour
mode anomoly.

Windows automatically realize the pallettes of all the objects in the
active form. I'm not sure if it's an API call to realize the pallettes
of all the forms at once. The AVI is not really in the same form as the
object where you put it, is in its own form.
Option 1 (the {*filter*}e): edit the pallettes of all the objects by hand
to make them respond to exactly the same pallette.
Option 2 (the easy one): use a 1 Mb card in 12 or more color bits
