** 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...

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.

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... :)

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!

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.

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.

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

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.

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.

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

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.

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)
Started from scratch.
Downloaded v02.03.00
Downloaded v02.03.01
Modified v02.03.01 with TypeOf changes
Copied v02.03.01 cTreeView.cls to v02.03.00
Changed v02.03.00 'Left' and 'Right' to 'Scroll Left' and 'Scroll Right'
Recompiled v02.03.00 - Successfull !!!

Great Code. I can tell you put lots of time into it...
I found a problem with this. When you add a refrence to your dll.
Public Enum eCodeScrollView '## Scroll Treeview
[Home] = 0
[Page Up] = 1
[Up] = 2
[Down] = 3
[Page Down] = 4
[End] = 5
[Left] = 6 *********
[Page Left] = 7
[Line Left] = 8
[Line Right] = 9
[Page Right] = 10
[Right] = 11 *********
End Enum
Because this is a public enum you can't use left or left$ or Right or Right$. I have seen this problem before. Just remeber use _ In all your enums and then you should not conflict with VB's.
