(About the author)
 
      In my endeavor the make a weather program for my computer that would scroll weather information, I came to make this code. I was looking for a place to scroll the information without bothering any other programs and without the form taking focus. I was looking for the perfect place. I found it but it was of course occupied by something else. That something else was the task tray (Those small little icons and the clock in the bottom right hand corner of most windows computers). Well I said to myself how shall I take that area. I thought I would simply shape my form to that of the trays window. Then make my form a child of that window and set it's position to the topmost. Well my idea was correct and it works perfectly. You can use this technique for any window, it is far less involved then many other attempts witch require sub-classing. The window will resize to the RECT of the tray when the Task bar is resize and or moved and call the form to repaint also. I hope all of you can get something useful out of this I know have. *NEW* YOU can now resize the tray by doing a call ResizeTray (Number to resize by,A 1 or a 2 for rither making it larger or smaller) so call resizetray 11,1 would add eleven icons to the tray and call resizetray 11,2 would subtract eleven icons

You get 5 globes from me. I will 
definitely use this in one of my 
applications. Maybe you have an answer 
to a similar problem that I have. I 
have an application (in Dutch, see nice 
screenshots at 
http://www.beursmonitor.com) with does 
a lot with stock quotes (including a 
couple of tickertapes) Using your code 
for an other tickertape would be a nice 
extra. Currently I have a tickertape 
which is using a timer to reposition a 
form over the titlebar of any active 
application. This is disturbed a bit 
when the processor is 100% occupied. I 
already tried the SetParent function 
but this does not work (MSDN tells me: 
The new parent window and the child 
window must belong to the same 
application) Zo how come your's is 
working? One other thing: You can make 
the scrolling text look very nice by 
using a very easy to use textanimation 
control I wrote. Just have a look at

Well that's because the MSDN 
information is wrong :).  It works 
because my application is not it's own 
parent but a child of another window 
this allows the main application to be 
able to send the window the calls to 
change the text resize the lables ect.  
You'll run into a problem if you try to 
take a child form and set it's parent 
to 0 and try to make it it's own 
parent.  It will work but it will 
effectivly sever the link between the 
actually running program and the 
graphical window.  So nothing will 
update and your program will crash.  
Thanx for the scrolling text thing by 
the way :).  Am I understanding you 
right that your positioning the form 
over the titbar area to display info?  
What Information are you displaying?

I have an Idea.. 
Have your form 
watch for the currently active window 
as it does now second have it check to 
see if the window state is not 
minimized if its not minimized then the 
person can see the title bar have the 
form then position itself over the 
titlebar.  Now when the form is 
minimized or losses focus the form will 
either move to the next active window 
or hide while the form is minimized.  
This will help a little in cutting down 
on resources.  On the other hand if 
it's just text you want displayed you 
could just change the caption of the 
currently active window to that of your 
text.. not sur eif this will do what 
you want but if you need help or if im 
just not egttig what your saying e-mail 
me at nemopsj@aol.com I'll try to help 
you out.

Thanks for the info. I will defenitely 
try this. I am using it in combination 
with the textanimation control to 
display the current stock quotes in the 
titlebar of the active application. 
When I will get it to work as a child 
form I will strip it form my 
application and post it on PSC.

Hi, I tried the setparent but then even 
if i set the window to the topmost it 
wil be displayed behind the titlebar. 
So i don't thinkt that a parent child 
relationship will work in my case. The 
second thing that i tried was hooking 
into the paint function of the 
application by using the lpPrevWndProc 
= apiSetWindowLong(hwnd, GWL_WNDPROC, 
AddrOf(strFunctionName)) (This is the 
SetWindowLongA in user32) But this wil 
return an access denied error. So I am 
back to the beginning. Does somebody 
have an idea how i can paint into the 
titlebar of any application?

You know there is a way...  You have to 
search for "Animated Title bar".  This 
is what I found it animates the title 
bar with a picture but im sure with 
some tinkering/Canimbalising you can 
figure out how to get it to 
work.

p.s. To all 
those who enjoy my systray program I'm 
adding a feature to expand the systray 
so it's large enough to hold whatever 
you want whilst also resizing the rest 
of the task bar so everything fits!

Hi, As you can see the titlebar app 
is using the SetWindowLong and that 
will only work for the current 
application and i want to do this for 
all applications that are running. 
That new feature sounds good!

Why does it need to be for all 
windows... that WILL eat up processing 
plus it's impracticle.  I mean the 
currently active window will be the 
only one the user is looking at or at 
least the only one he will be paying 
attention too.  So having it on all the 
others is pointless.  Well at least in 
my mind.

This is nice, it would be cool if you 
could get the number of icons there 
before so that way you can have kinda a 
standard size like I would like mine to 
always be 6 icons big or something no 
matter how much they have
