| | | ** Release 6 ** Added BackMode, BackColor, BackPicture, BackFileName, DisableMultiSelect, New Tutorial (Disable Multi-Node Select), updated Tutorial 1 (demonstrate new Back features) and added Animated TreeView Image Background (YES - A first! Pretty unique huh!). BackColor & BackPicture work independantly of the Nodes therefore Nodes maintain their original colors! No other VB code does this - enjoy!
** Release 5 - 26 New Features, 2 new Tutorials ** Now boasts 75 Properties & Methods (features), 7 tutorial/example applications and detailed Html help files and still growing!
New features include:- **Disabled Nodes Interface** with full keyboard and mouse support (Unique!), HitTestEx (with comprehensive feedback), IsNodeTextUnique, IsPathExpanded, NodeAbsolutePosition, NodeAbsoluteIndex, NodeCoord, NodeCountChildren (recursively for all sub-branches), NodeFindEx1 (containing), NodeFindEx2 (advanced pattern-matching), NodeFindObjectInTag (advanced pattern-matching), NodePosition, NodeUniqueText, SubNodesSorted, and EditLabelMaxLength.
The Disabled Nodes Interface allows individual nodes to be enabled/disabled (not selectable) and toggled with the ability to affect child nodes with a single command; disabled Fore/Back colours and Bold state are programmable (preserves the original Forecolor, Backcolor and bold status of each individual node) and fires a StateChange event when a node or a range of nodes are disabled/enabled. The treeview control by itself is a powerful control when used properly.
This wrapper is designed to deliver the most common and also complicated features that's expected from the control but are not included or are very difficult to implement. [See the animated ScreenShots for examples of the new features]
The included tutorials also demonstrate how to tie multiple ADO recordsets to a Treeview control with drag'n'drop automatic updates(move & copy nodes and branches), load-on-demand for instataneous display of large amounts of data; benchmarking; cursor management; TabStrip management; working with common dialogs through APIs; and much, much more...

I wonder how you still can improve
this...
Great, great work! (as usual)

Overwhelming - you lucky people *****
|
8/3/2002 8:05:12 AM:Coite Moss
Exceptional - All 5 Globes - No doubt
this kills the TreeView control
supplied with VB. Go away Microsoft, we
have Slider.... If -all you need- is
the Treeview this really reduces
project distribution size.
|
8/5/2002 6:05:38 AM:Valenitn
I wonder if you can solve a problem
with TreeView when visible part of the
structure gets normalized by left
points of nodes, thus hiding checkboxes
under left side of TreeView panel. It's
no problem while user controls tree by
mouse, but very uncomfortable if
checkboxes are needed and actions are
controlled programmatically. The cure
is API, of course, but the tricky part
is it doesn't valid for all and every
config. When I've tried it and
consulted with some programmer, the
same code did well on his config (VB6
SP3 or 4, NT), but failed on mine (Win
98, otherwise all the same). No crash,
just doing nothing...

I can't believe this code!! There's too
many features that i can't possibly use
them all! The one thing i learnt from
your project was invaluable:
preprocessor statements like #if. I
didn't know vb had any until I saw your
code. If only I could vote higher than
a 5... :)
|
8/6/2002 12:19:45 PM:speedy5
I have a question, may I use this for
my possibly commercial application (you
will be given credit)? Please reply
quickly.
Thanks,
Speedy
|
8/6/2002 8:39:45 PM:Slider
Speedy5,
Thanks for your comments.
I'm happy for you to use the code in
your commercial app.

Awesome Dude. One of the best
Treeviews I've seen to date. Your
tutorial is great. It shows
functionality extremely effectively.
Five ++++

8/11/2002 1:11:08 AM:Slider
Steve, Thanks for your comments & vote!
Much time has gone into this
project & it's great to see the
comments and votes - it's what tells me
that I have to keep expanding the
project with many new
features.
There are a couple of guys
(maybe the same one) that have casted
Average votes with no feedback - I've
posted them asking why but no
response...
People, if you find the
code useful, needs work, or have ideas
that you'd like included, then please
let me know!

Nicely Done!
What I Would Like To
See Is. When You Scroll The Tree The
Picture Stays At It's Same Position.
It Gets A Bit Hard On The Eyes When
Your Scrolling The Tree And The Picture
Is Scrolling As Well.
Apart From My
Pickiness Very Nicley Done!

Slider,
This is one of the best
submissions ever offered on PSC - thank
you for your generosity in sharing your
hard work.
I'd give you a 6 globes

Simply
excellent!

8/19/2002 4:43:38 PM:Rasputin
...one last thing.
The only thing
that can explain votes of less than 5

JEALOUSY!
Just take it as a
compliment Slider, and keep up the
great work!

Very nice work. One question -- any
chance of getting multiline values
(text wrapping that rewraps when the
control is resized) displayed in a
treeview node? Any pointers for where
to look to learn how to add that?
Thanks.

Amazing what you can do with this
control - Love yr work! 5*s - Keep it

recieve error during .HookCtrl
tvwDialog procedure that it is an
invalid control, and that it must be a
VB6 Tree View control.. Any Ideas?
|
9/4/2002 2:15:18 PM:Jason Curns
PS, I am using VB 6 SP5
|
9/5/2002 12:21:46 AM:Slider
Jason, there are a couple of different
versions of the MSCOMCTL.OCX file. As
minor as they are, it's causing an the
problem. Recompile the DLL and the
problem will go away.

anything betetr than this one. GReat
great great
|
10/14/2002 2:26:16 PM:
WOW - Great work!
Excellent code, for
sure, but what makes your project worth
MORE than 5 is your willingness to
improve it based on feedback from
users. Plus, of course, your very
noble gesture of letting less-learned
programmers (like me) benefit by seeing
your work.
OUTSTANDING
THANK
YOU * 100k

One more comment - the sign of a true
professional and a really GREAT
programmer, is attention to
details.
Although the animated
background is absolutely stunning! But
honestly, I found the detail of .Tag
that you did NOT overlook, to have been
more useful!
The M$ treeview uses a
string for .Tag, but you fixed their
oversight and gave me a variant which
is what I needed.

11/2/2002 12:55:11 AM:
Slider...Excellent work. I can
actually make sense out of this code.
You got 5 globes from me....its saving
me from 50 cups of coffee and a long
frustrating weekend! True Pro. I'll
have to send you a copy of the
application that I'm using it in...
|
11/21/2002 4:02:09 AM:
Look very good!
But I cannot try it,
everytime I open the projects, this or
that message comes out.
Is there any
pre-requisite to install first?
I
try to recompile the dll, but it gives
me error:
Missing Microsoft XML
V3.0
|
11/21/2002 5:54:20 AM:Slider
There is a readme. Pls follow the
instruction and it should fix the
problems that you're experencing.

11/21/2002 12:05:41 PM:
Slider : Outstanding!!!!. Thank you

11/24/2002 2:48:15 AM:
Does it work in VBA (Word, Excel. ...) ?
|
12/14/2002 9:22:04 AM:Peter Van der Straeten
Great control, dude. Just a tiny little
glitch. You expose in the enum
ECodeScrollView a constant named LEFT,
this is a VB-Reserved word. It somehow
interferes with normal use of vb LEFT
function. I can't get my project to
compile when i use your DLL. Solved it
by renaming LEFT to KLEFT in the ENUM
and function that uses the ENUM.
Recomend you do the same.
scincerely
Peter

1/15/2003 4:41:34 AM:Andy Bretl
I have seen some of controls of this
kind during my carrer, but none of them
was as excellent as this one is. It
also finished off some
missunderstanding of treeviews that I
seem to have (until now...). This piece
of work is definitely worth an
additional globe (not only 5). Even if
I knew somebody who had done that
before, I am quite sure he won't simply
share it. Very kind ;)..... Seize the
Day and keep on going , Andy

1/16/2003 12:29:09 PM:
I read from your answers to the people
comments that you have no problem to
use it in commercia app. thanks. one
more thing I wonder if you can do the
treeview to be display in right to left
position! it will help a lot. thanx
again
|
1/17/2003 9:16:09 AM:
Man, the world needs more controls like
this! Keep up the good work!
|
1/23/2003 8:01:54 PM:
Men! you blew ma mind away, I've been
cooking treeview for days now, your
code will get my stuff done in minutes.
GOD IN HEAVEN WHO IS THE BEST
PROGRAMMER EVER WILL BLESS YOU.
|
2/19/2003 5:35:45 PM:
Here is the solution to Left$. Put
VBA. infront of it. VBA.Left$. That
will solve the conflict with this DLL.
|
2/27/2003 4:55:09 AM:
Real nice piece of code. I was using
version 1 for some time, but this is
much better. I added some code for
showing or not showing checkboxes. If
you're interested please mail.
Also I
had the same problem with Left. I found
it better to change the enum to Kleft
than to change all the rest of my code.

3/31/2003 4:37:07 PM:
When using a pointer icon to show
dragging: the icon needs an offset
coordinate like x,y of -3, -15 so the
point of the pointer is accurate.
|
3/31/2003 4:47:58 PM:
I'd like to drag the node text as well
as the node icon. And over lay the
NoDrag Icon onto the text when
appropriate.

3/31/2003 5:01:45 PM:
On a node with children move I was
updating my db behind the TreeView with
a single sql statement then reloading
the entire treeview because the nested
node move was just too complex. Your
.nodemove mothod looks like I can save
some bandwidth and lagtime. Thanks

Hi Slider,
Thanks, you did a very good
job and it was very helpful to my
project. Only the ExpandAll function
doesn't seem to work quit well / is
very slow with big trees. I've build
some checks in my program and it seemed
as if this method was again and again
expanding from the root node. A
complete test tree needed only 500
expands, but the ExpandAll method took
more then 100.000 expands.
I wrote a
recursive procedure which did only the
necessary expands which was a lot
faster (something like 15 seconds for
500 expands).
Still with big trees my
procedure was very slow too. Do you
have any suggestions how I can make an
ExpandAll faster? By the way: I use ADO
to expand the tree, but the queries
took only a fraction of the complete
time for expanding.
Hope you can say
something about this.
Kind regards

Hi all,
Hoping to get some help on
compiling to vbTree.dll.
Worked the
first few times but now I have some
sort of incombatibility.
Compiling:
DLL : set class Instancing = 5 -
MultiUse
Have done this but still
getting:
The xxxx class module was
found in the version-compatible
component, but not in the project.
I
click the break compatibility and
OK
then get:
Compile error:
Private
object modules cannot be used in puclib
object modules as parameters or return
types for public procedures, as public
data members, or as fields of public
user defined types
I'm sure I've
missed something here.
Any help from
you .dll experts would be greatly
appreciated.

4/24/2003 7:51:43 PM:
Solved!
(The freezing in debug mode
was driving me mad. So I had to return
to the .Dll)

I found a critical bug, with the drag
and drop sample, add two command
buttons, in one use Save [XML or
Binary] and hte other Load [XML or
Binary] run the app, move some nodes
around and try and save, close and try
loading them, looks like it doesnt save
it nicely once its been moved around...
any fix?

of my graduation project:) if you do
not mind and I have only one week to
discus this project so please help me
otherwise :( I ll not pass this
