I think that you have a problem with your monitor or
video-card. My toolbar images/buttons are as solid as a rock
NO flicker.
The code being used is the same as any windows program uses
to place the display the buttons. The code uses Windows
same built in class that and images that the word toolbar
uses.
I tried my toolbar at 32bit true color 1024/768 with no
problem.
Take the program to a different system with a different
monitor and different videocard and try it.

I just tried it on my Win98 system at home. It flickers as well.
My Win95 system at work flickers. My Win2K system does not.
By "flicker," I just mean you can clearly make out the redrawing of the
client area. It's obvious.
I find it hard to believe it's because of my video cards. And I'm surprised
nobody else experiences it. Am I unique in this?!

Let me clarify: The flicker occurs when you RESIZE the window. Drag the
bottom right handle around and report your results.

If I grab the bottom right corner and resize the window, the
buttons do not flicker in any way.
You have a bad videocard or a out of date video driver
I have seen bad videocards that cause dots to appear on a control
when a mouse is moved around on the screen and many other weird
problems. Try changing your videocard to different number of
colors and resolution. I've seen many problems with videocards
bad drivers, bad video memory, bad video bios, etc.
The monitor is a outside possibility.

No, it moved smoothly.

It's not just Bernie's program, either. Mike's editor flickers, and most
every other EUPHORIA for Windows program I've seen flickers. All the
Win32Lib examples flicker a LITTLE bit, but that's just because there are
only a very few items in the client area. (Is this the right use of
"client," to mean whatever is within the window's borders?)
But, when I resize this Outlook mail compose window, it doesn't flicker at
all.
Weird!!!
I'm sure it's something simple and once we- I mean you guys- figure it out,
we'll not have flickering windows anymore. :)

Derek, thanks so much! I knew one of you gurus would get it.
I like the fact that it's so hard to stump this list... No, I'd say
impossible! :)

Derek:
You should not need to change the style.
If you are using a TNT2 Vanta 16 megs or less be sure that
your motherboard bios AGP setting is set for 2X NOT 4X or automatic.
Some manufactors when they decided to go to AGP from PCI video
cards took their PCI cards and they just moved them to the AGP
buss without redesigning the card, so some video cards are not
really AGP cards and can have driver problems.
ME has alot of driver issues so be sure that you are using the
correct driver and that a driver is a bug free driver.
I'am using a S3 Savage4 AGP 2x with 16 megs of memory
running at 800x600 32bits at 85hz
with a memory clock 125mhz with a core clock 110hz
with a K6-2 at 500mhz 128megs of memory.
PS: An for some users that don't seem to think I know what
I'am talking about, I have been working with computers for
46 years probably before some of you were even born.

Derek:
I tried the toolbar.exw in the win32lib and I don't see any
jitter or sparkle.
I only see a normal repaint when the left mouse button is released
and that only happens once.
I tried my tbar.exw on another system that has a award bios
but it has a VGA card and it seems to have no problem.
Maybe I don't understand what the users are complaining about.
Your motherboard manufacture may have a bios upgrade for your
BIOS if it is a flash BIOS, But be careful if you try to flash
it that you don't wipe it out. I'am suprised that your motherboard
has a AGP slot but nothing in the BIOS for it. Maybe there is a
jumper for 2X/4X on the motherboard, maybe you could chech your
manual.

I'am sorry but I don't understand what that has to do with the
toolbar ?
I don't think the toolbar is part of the client area.
