Greetings, I am writing a graphical routine for a screen saver and need
a little advice. What I would like to do is to draw a bmp picture on
the screen pixel by pixel (in some attractive fashion). This is a Windows
screen saver and would like to be a 256 colour bmp file.

If I put the bitmap on the form as a picture how to I just turn on the
required pixels on at a time ? (this would be the prefered solution as
it would not require an external file).

If I read in an external bmp file how do I set the windows palette and
then plot the pixels ? (I presume this is done my some windows calls?)

Any advice or sample code (VB/Pascal or C would be great) anyone ?

Thanks, Simon

While unfortunately I don't have time to provide a detailed example, may I
refer you to the MSDN disk and the hints and tips articles. In particular,
refer to Tip 45: Using BitBlt to display bitmaps, which explains how to read
in bitmap files in VB as opposed to using LoadBitMap, etc.

Interestingly, I see my own source code in this particular tip; MS obviously
browse through clbv and abstract useful stuff (I posted some of this over a
year ago); kinda weird to see your own code on their disk, though.

Wonder if Chairman Bill also has a private list of all the MS flamers; it'd
be about the size of the LA phone book by now - he's probably got us all on
a SQL Server database <g>

Hi,
  I would like know how you write a screen saver file which is not exe file.
Because I like to learn it, please send me e-mail to tell me.
  Thanks man!

Andrew, you may also want to tell them how to search the MSDN.  I
guess if they subscribe to the MSDN and they didn't find it there then
they need help searching the CD(s).

That's impossible. A screen saver is an exe file. Look in VBT&T or
VBKB for the code.
