Treeview structure

how to create treeview structure using java........like a hierarchy of folder stored in hard disk. does TreeMap class meets the objective..?

I'm guessing you mean a graphical tree. TreeMap is a data structure, so not what you're after. What you want is a JTree

Hierarchical treeview structure in Reports

Hi,
I am working with an MNC, can anybody help me out by valuable guidelines in doing an hierarchical treeview structure in Reports.
Your early response would b helpful to me.
Bye

HI
see this site you wil find lots of examples
http://www.sapdev.co.uk/reporting/alv/alvtree.htm
The ALV tree report produces uses OBJECT METHOD functionality in-order to produce a
tree structured ALV output.
The creation of an ALVtree report first requires the creation of a simple program to build the ALV
details such as the fieldcatalog and to call a screen which will be used to display the ALVTree.
The screen should be created with a 'custom control' where you wish the ALVtree report to appear.
For the following example it will have the name 'SCREEN_CONTAINER'.

Creation of 'INCLUDES' to store ALVtree code
Three includes need to be created in-order to store the ABAP code required for the ALVtree report.
Typically these will be one for the PBO modules, one for PAI modules and one for the subroutines(FORMs):
 *Includes
 include zdemo_alvtreeo01. "Screen PBO Modules
 include zdemo_alvtreei01. "Screen PAI Modules
 include zdemo_alvtreef01. "ABAP Subroutines(FORMS)
If you are using the code provide within the ALVtree section of this web site simply create the includes by
un-commenting the 'Includes' section within the code(see below) and double clicking on the name
i.e. 'zdemo_alvtreeo01'. Obviously these can be renamed.
*Includes
*include zdemo_alvtreeo01. "Screen PBO Modules
*include zdemo_alvtreei01. "Screen PAI Modules
*include zdemo_alvtreef01. "ABAP Subroutines(FORMS)
*Start-of-selection.
start-of-selection.
Create Screen along with PBO and PAI modules for screen
The next step is to create screen 100, to do this double click on the '100' within the call screen
command(Call screen 100.). Enter short description and select 'Normal' as screen type.
To create the PBO and PAI modules insert that code below into the screen's flow logic. Much of this code
should automatically have been inserted during screen creation but with the module lines commented out.
Simple remove the comments and double click the module name(STATUS_0100 and
USER_COMMAND_0100) in-order to create them, this will display the perform/module creation screen.
The MODULES are usually created within two includes one ending in 'O01' for PBO modules and
one ending in 'I01' for PAI modules(See code below).
Please note in order for these includes to be displayed on the creation screen they need to have be
created along with the following lines of code added to the main prog(see previous step):
 INCLUDE ZDEMO_ALVTREEO01. "Screen PBO Modules
 INCLUDE ZDEMO_ALVTREEI01. "Screen PAI Modules
Otherwise use the 'New Include' entry and SAP will add the necassary line for you.

Define OK CODE(SY-UCOMM) variable
In order to define the OK CODE you must fist declare a variable of type SY-UCOM and then insert this
variable into the OK code declaration within the element list (see screen shot below). If you have used
the code contained on the iwebsite the ok code should already have been declared as OK_CODE.
 i.e. OK_CODE like sy-ucom.
Note: there is also a variable called SAVE_OK, it is good practice to store the returned ok code into
a work area as soon as you enter the PAI processing.
Add screen control to PAI module(INCLUDE Z......I01)
The following code adds simple screen control to the report and whenever the user presses the cancel,
exit or back icon they will exit from the report. It also processes the ALVtree user interactions within the
'others' case statement
 INCLUDE Z......I01 *
*& Module USER_COMMAND_0100 INPUT
 text
module user_command_0100 input.
DATA return TYPE REF TO cl_gui_event.
save_ok = ok_code.
case ok_code.
 when 'BACK' or '%EX' or 'RW'.
 Exit program
 leave to screen 0.
Process ALVtree user actions
 when others.
 call method cl_gui_cfw=>get_current_event_object
 receiving
 event_object = return.
 call method cl_gui_cfw=>dispatch.
endcase.
endmodule. " USER_COMMAND_0100 INPUT
Create pf-status
In order to created the pf-status for the screen you need to un-comment '* SET PF-STATUS 'xxxxxxxx'
and give it a name.
 i.e. SET PF-STATUS 'STATUS1'.
Step 1
Now double click on 'STATUS1' in-order to create the pf-status. Enter short text, select status type as
'Online status' and click save.
Step2
You should now be presented with the status creation screen. Choose 'Adjust template' from the Extras menu
(4.6 onwards only).
Step 3
Now select 'List status' and click the green tick (see below).
Step 3
All the basic menu bars/buttons should now have been entered. Now click save then activate. The
pf-status has now been completed.
Once you have the main program code in place to call the screen which will display the
ALVtree, you now need to setup the actual ALVtree and populate it. As this is screen
based(dialog) the display coding will be performed within the PBO screen module.
Therefor you need to add the following processes to the PBO(STATUS_0100) module
of the screen.
Create Custom control
Via screen painter insert 'custom control' on to screen and give it the name 'SCREEN_CONTAINER'. This is
the possition the ALVtree will appear so align appropriately.

Would like to create a script for list all elements and structure of an indesign document

Hello everybody,
I'm a very beginner in indesign scripting.
I would like to create a script in order to list all elements and the inner structure of a n indesign document.
The aim for me is to understand how elements are sorted and arranged into indesign, and be able to find an specific element by its item name.
The output document could be an xml or txt document with a treeview structure.
I would like have a rough idea of which kind of javascript code I should use for that.
Thanks for answers.

Hi Ossydoc,
You can use Muse to create such a website. All you need to do is, create links in Muse for the sermons and select " link to File " in the hyperlink option and link to those Mp3 files.
Please refer to this screenshot :- http://prntscr.com/4xvdup
Now, when you publish your site, Muse would automatically upload those files onto the server and the users would then be able to listen as well as download those sermons using the links on your site.
Hope this helps

Rohit Nair

How can i write also to xml file the settings of the Tag property to identify if it's "file" or "directory" ?

The first thing i'm doing is to get from my ftp server all the ftp content information and i tag it so i can identify later if it's a file or a directory:
private int total_dirs;
private int searched_until_now_dirs;
private int max_percentage;
private TreeNode directories_real_time;
private string SummaryText;
private TreeNode CreateDirectoryNode(string path, string name , int recursive_levl )
var directoryNode = new TreeNode(name);
var directoryListing = GetDirectoryListing(path);
var directories = directoryListing.Where(d => d.IsDirectory);
var files = directoryListing.Where(d => !d.IsDirectory);
total_dirs += directories.Count<FTPListDetail>();
searched_until_now_dirs++;
int percentage = 0;
foreach (var dir in directories)
directoryNode.Nodes.Add(CreateDirectoryNode(dir.FullPath, dir.Name, recursive_levl+1));
if (recursive_levl == 1)
TreeNode temp_tn = (TreeNode)directoryNode.Clone();
this.BeginInvoke(new MethodInvoker( delegate
UpdateList(temp_tn);
percentage = (searched_until_now_dirs * 100) / total_dirs;
if (percentage > max_percentage)
SummaryText = String.Format("Searched dirs {0} / Total dirs {1}", searched_until_now_dirs, total_dirs);
max_percentage = percentage;
backgroundWorker1.ReportProgress(percentage, SummaryText);
percentage = (searched_until_now_dirs * 100) / total_dirs;
if (percentage > max_percentage)
SummaryText = String.Format("Searched dirs {0} / Total dirs {1}", searched_until_now_dirs, total_dirs);
max_percentage = percentage;
backgroundWorker1.ReportProgress(percentage, SummaryText);
foreach (var file in files)
TreeNode file_tree_node = new TreeNode(file.Name);
file_tree_node.Tag = "file";
directoryNode.Nodes.Add(file_tree_node);
numberOfFiles.Add(file.FullPath);
return directoryNode;
The line i'm using to Tag is:
file_tree_node.Tag = "file";
So i know what is "file" then i make a simple check if the Tag is not null then i know it's a "file" if it's null then it's directory.
For example this is how i'm checking if it's file or directory after getting all the content from my ftp server:
if (treeViewMS1.SelectedNode.Tag != null)
string s = (string)treeViewMS1.SelectedNode.Tag;
if (s == "file")
file = false;
DeleteFile(treeViewMS1.SelectedNode.FullPath, file);
else
RemoveDirectoriesRecursive(treeViewMS1.SelectedNode, treeViewMS1.SelectedNode.FullPath);
I also update in real time when getting the content of the ftp server xml file on my hard disk with the treeView structure information so when i'm running the program each time it will load the treeView structure with all directories and files.
This is the class of the xml file:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Xml;
using System.Windows.Forms;
namespace FTP_ProgressBar
class TreeViewXmlPopulation
// Xml tag for node, e.g. 'node' in case of <node></node>
private const string XmlNodeTag = "node";
// Xml attributes for node e.g. <node text="Asia" tag=""
// imageindex="1"></node>
private const string XmlNodeTextAtt = "text";
private const string XmlNodeTagAtt = "tag";
private const string XmlNodeImageIndexAtt = "imageindex";
public static void DeserializeTreeView(TreeView treeView, string fileName)
XmlTextReader reader = null;
try
// disabling re-drawing of treeview till all nodes are added
treeView.BeginUpdate();
reader = new XmlTextReader(fileName);
TreeNode parentNode = null;
while (reader.Read())
if (reader.NodeType == XmlNodeType.Element)
if (reader.Name == XmlNodeTag)
TreeNode newNode = new TreeNode();
bool isEmptyElement = reader.IsEmptyElement;
// loading node attributes
int attributeCount = reader.AttributeCount;
if (attributeCount > 0)
for (int i = 0; i < attributeCount; i++)
reader.MoveToAttribute(i);
SetAttributeValue(newNode,
reader.Name, reader.Value);
// add new node to Parent Node or TreeView
if (parentNode != null)
parentNode.Nodes.Add(newNode);
else
treeView.Nodes.Add(newNode);
// making current node 'ParentNode' if its not empty
if (!isEmptyElement)
parentNode = newNode;
// moving up to in TreeView if end tag is encountered
else if (reader.NodeType == XmlNodeType.EndElement)
if (reader.Name == XmlNodeTag)
parentNode = parentNode.Parent;
else if (reader.NodeType == XmlNodeType.XmlDeclaration)
//Ignore Xml Declaration
else if (reader.NodeType == XmlNodeType.None)
return;
else if (reader.NodeType == XmlNodeType.Text)
parentNode.Nodes.Add(reader.Value);
finally
// enabling redrawing of treeview after all nodes are added
treeView.EndUpdate();
reader.Close();
/// <summary>
/// Used by Deserialize method for setting properties of
/// TreeNode from xml node attributes
/// </summary>
private static void SetAttributeValue(TreeNode node,
string propertyName, string value)
if (propertyName == XmlNodeTextAtt)
node.Text = value;
else if (propertyName == XmlNodeImageIndexAtt)
node.ImageIndex = int.Parse(value);
else if (propertyName == XmlNodeTagAtt)
node.Tag = value;
public static void SerializeTreeView(TreeView treeView, string fileName)
XmlTextWriter textWriter = new XmlTextWriter(fileName,
System.Text.Encoding.ASCII);
// writing the xml declaration tag
textWriter.WriteStartDocument();
//textWriter.WriteRaw("\r\n");
// writing the main tag that encloses all node tags
textWriter.WriteStartElement("TreeView");
// save the nodes, recursive method
SaveNodes(treeView.Nodes, textWriter);
textWriter.WriteEndElement();
textWriter.Close();
private static void SaveNodes(TreeNodeCollection nodesCollection,
XmlTextWriter textWriter)
for (int i = 0; i < nodesCollection.Count; i++)
TreeNode node = nodesCollection[i];
textWriter.WriteStartElement(XmlNodeTag);
textWriter.WriteAttributeString(XmlNodeTextAtt,
node.Text);
textWriter.WriteAttributeString(
XmlNodeImageIndexAtt, node.ImageIndex.ToString());
if (node.Tag != null)
textWriter.WriteAttributeString(XmlNodeTagAtt,
node.Tag.ToString());
// add other node properties to serialize here
if (node.Nodes.Count > 0)
SaveNodes(node.Nodes, textWriter);
textWriter.WriteEndElement();
And this is how i'm using the class this method i'm calling it inside the CreateDirectoryNode and i'm updating the treeView in real time when getting the ftp content from the server i build the treeView structure in real time.
DateTime last_update;
private void UpdateList(TreeNode tn_rt)
TimeSpan ts = DateTime.Now - last_update;
if (ts.TotalMilliseconds > 200)
last_update = DateTime.Now;
treeViewMS1.BeginUpdate();
treeViewMS1.Nodes.Clear();
treeViewMS1.Nodes.Add(tn_rt);
TreeViewXmlPopulation.SerializeTreeView(treeViewMS1, @"c:\XmlFile\Original.xml");
ExpandToLevel(treeViewMS1.Nodes, 1);
treeViewMS1.EndUpdate();
And when i'm running the program again in the constructor i'm doing:
if (File.Exists(@"c:\XmlFile\Original.xml"))
TreeViewXmlPopulation.DeserializeTreeView(treeViewMS1, @"c:\XmlFile\Original.xml");
My question is how can i update the xml file in real time like i'm doing now but also with the Tag property so next time i will run the program and will not get the content from the ftp i will know in the treeView what is file and what is directory.
The problem is that now if i will run the program the Tag property is null. I must get the ftp content from the server each time.
But i want that withoutout getting the ftp content from server to Tag each file as file in the treeView structure.
So what i need is somehow where i;m Tagging "file" or maybe when updating the treeView also to add something to the xml file so when i will run the progrma again and read back the xml file it will also Tag the files in the treeView.

Thanks a lot for the help so far, I've created a method to check the basePanel for any components it holds and try to create a JTree display from it. The code I currently have is :
 public void updateObjectSelector()
 // Setup the tree viewer
 DefaultMutableTreeNode root = new DefaultMutableTreeNode(basePanel.getClass());
 addChildren(root, basePanel);
 tree = new JTree(root);
 public void addChildren(DefaultMutableTreeNode root, JPanel parent)
 Component [] children = parent.getComponents();
 for(int i = 0; i < children.length; i++)
 DefaultMutableTreeNode child = new DefaultMutableTreeNode(children.getClass());
 try
 addChildren(child, (JPanel) children[i]);
 catch(ClassCastException e)
 root.add(child);
basePanel and tree are both global variables. basePanel is the root Panel to which everything is added to.
I am calling "updateObjectSelector()" every time a component is added to the basePanel but at the moment all I can get displayed by the JTree is the getClass() of the basePanel, none of its children are being displayed. Can anyone see what I have done wrong here?
Many thanks again for all your help so far.

Hi Jyrkis700,
If you want to add the other domain's information to TreeView, you can try the cmdlet "Get-ADUser -Server otherdoman.com -Credential otherdomain\Administrator" instead of "Invoke-Command" and "Enter-Pssession":
Get-ADUser ann –Server test.server.com -Credentail TEST\Administrator

Adding/removing members from another forest or domain to groups in Active Directory

Hi,
Actually my requirement is, I would like to pass site name and document library name as a parameter and get a folders and files from the document library and form the directory structure by using Treeview control in my web site.
How should i get? Using Web service / object model?
Web service would return the dataset as a result so from that how could i form the directory structure using Treeview control.
I will select specified files and folders then i ll update sharepoint document library columns for corresponding selected files.
Can anyone help over this, that would be great appreciate.
Thanks in Advance.

Hello,
Here is the code to iterate through sites and lists:
//iterate through sites and lists
SPSecurity.RunWithElevatedPrivileges(delegate()

using (SPWeb oWebsite = site.OpenWeb())
SPListCollection collList = oWebsite.Lists;
foreach (SPList oList in collList)
{//your code goes here }
Then use RecursiveAll to get all files and folders.

Tree structure xtras and flash buttons

im doing a prototype of small project in Director for an
e-learning application. i need to build a tree like structure based
menu with graphical icons as the main navigation method of the
movie. there is a TreeView Xtra by broadband but it is too
expensive for my client's budget. this is the first job of this
type im getting. so i need to know is there any other way to get
this done??? i thought of doing the menu in flash but how to give
navigation commands to director timeline from several symbol
components inside a flash asset component i dont know. your
experience on this will be much appreciate if shared with me.
regards
Bhanuka

There are various ways of having Flash inform Director of
items that are
interacted with. Search the docs for getURL(), or search the

Portal Eventing JSP TreeView

I am trying to refactor a piece of code that was originally designed using HTMLB to create a tree view role menu that invokes an event in another iView.
My question is, can portal eventing be done with traditional JavaScript as opposed to using HTMLB? We are not using WebDynPro for this project.
I would like to use a jsp treeview to re-engineer the existing htmlb tree structure, but wanted to get some feedback on the options...thanks

Hi Ryan,
> whether or not the eventing
> has to be done on the server side
The eventing between iViews is done by EPCF, and this is, as said, a pure JS framework. Often it might be senseful for the iView which gets "informed" by some other iView about some event with some event data, to use this data and to refresh itself. This depends on the concrete use case.
Having this said, it is obviously totally independent if you usue EPCF from some portal HTMLB-JSP, a "pure" JSP without HTMLB or a BSP - all of these things end up in HTML with the possibility to include JS - the EPCF calls.
See http://help.sap.com/saphelp_nw04/helpdata/en/82/04b340be3dff5fe10000000a155106/frameset.htm for further details.
> Can all of this be done without post backs
> to the server,
As said before, the eventing through EPCF works on client side, but in many cases it makes sense to refresh some iView with some data sent by the event.
Imagine a List-Details iView combination. The user has one iView with a list of products and another iView with the details of one product. By choosing one product in the list iView, this iView could raise an event, which is subscribed by the details iView, for example passing some product-ID. Now it would make sense to refresh the details iView with the ID given. The alternative would be to load all details data and only to show up the chosen details and to switch on the event. Two disadvantages: It's much harder to code and you may have a very long transmission/network time for the inital call of this iView.
> without using htmlb using JSP not BSP
See above, it's independent from the HTML-Layer.
> can you store a result set in a client side object,
> like a cookie, and if so, how?
For sure, somehow you can (at least some representation). But here I'm unsure again, in which direction this question aims, if this is really helpful.
Hope it helps

What does the directory structure of your module in
CVS look like? After checking out, does the directory
structure on disk reflect this properly? Yes, the directory structure in disk reflect properly with de CVS.
If you check the generated project settings, and look
on the Project Content page, are the Java Content
paths set correctly?Yes too.
This sounds like it may be some kind of bug. Any
information you can provide may help me put together
a reproducable test case so that I can report this.
Thanks,
BrianStep by step:
1 - I make de CVS connection... and it is ok.
2 - In the CVS Navigator, I checkout the selected module.
3 - After checkout, in the dialog "Handle New Files" I wish "Create New Project From Files".
In Application Navigator:
Applications
|__ module_name
|__ module_name [ip_cvs_server]
In System Navigator:
|__ module_name.jws
|__ module_name.jpr [ip_cvs_server]
|__ loading...
The project properties are ok, but in the this navigators I can´t see/access the files/directory strutucture of the project.
Thanks Brian!

Using Microsoft's TreeView Control in Forms 5.0

I created the OCX item, assigned it the OLE class 'COMCTL.TreeCtrl.1', inserted Microsoft TreeView Control 5.0, imported the appropriate OLE packages and set the appropriate OCX specific properties. With all that done, I created a simple code to clear the nodes collection and then populate it with two dummy nodes. The following is that snippet of code:
PROCEDURE DO$TREE_INIT(
i_study_id IN VARCHAR2 DEFAULT NULL
) IS
v_inodes COMCTLLIB_CONSTANTS.INODES;
v_inode0 COMCTLLIB_CONSTANTS.INODE;
v_inode1 COMCTLLIB_CONSTANTS.INODE;
BEGIN
-- Get pointer to the treeview control's nodes collection.
v_inodes := COMCTL_ITREEVIEW.NODES(:item('CB_MAIN.OCX_TREE').interface);
-- Clear nodes collection
COMCTL_INODES.CLEAR(v_inodes);
-- Create initial tree structure when provided with a study.
IF (i_study_id IS NOT NULL) THEN
v_inode0 := COMCTL_INODES.OLE_ADD(
interface => v_inodes
,relative => OLEVAR_NULL
,relationship => OLEVAR_NULL -- TO_VARIANT(COMCTLLIB_CONSTANTS.TVWFIRST, vtype => VT_R8)
,key => TO_VARIANT('STUD|AA|123|BC|12', vtype => VT_BSTR)
,text => TO_VARIANT('Dursban MOR Study (12312123)', vtype => VT_BSTR)
,image => OLEVAR_NULL
,selectedimage => OLEVAR_NULL
v_inode1 := COMCTL_INODES.OLE_ADD(
interface => v_inodes
,relative => TO_VARIANT(COMCTL_INODE.OLE_INDEX(v_inode0), vtype => VT_R8)
,relationship => TO_VARIANT(COMCTLLIB_CONSTANTS.TVWCHILD, vtype => VT_R8)
,key => TO_VARIANT('FF+|AA|123|BC|12', vtype => VT_BSTR)
,text => TO_VARIANT('Facility Functions', vtype => VT_BSTR)
,image => OLEVAR_NULL
,selectedimage => OLEVAR_NULL
END IF;
END DO$TREE_INIT;
My form complies properly but during runtime I get this error:
FRM-40735: < ... > trigger raised unhandled exception ORA-100504.
This form is very simple. It contains only one control block, the tree control, OLE packages, WHEN-NEW-FORM-INSTANCE trigger, and this package. I have tried everything within my understanding. Do you have any suggestions?
Any help would be appreciated.
Thanks,
Rahul

I have the same situation too. The only solution
I could think of is to install "Additional ActiveX"
from custom VB5 installation. Besides there is
a problem when VB6 is installed, because the controls are
called "Microsft TreeView ... (SP2)".
If you find any progress , keep me in touch :) ...

WCF RIA zero-one to many ultimate treeview

Hi,
I am using ultimate treeview extension (http://visualstudiogallery.msdn.microsoft.com/ca292c74-661c-48ba-8262-d79a2671c33f)
This requires a zero-one to many table. I have this working with a table.
However I need to connect to a WCF RIA service from the control. Currently using
public class WorksOrderTree
[Key()]
public int id { get; set; }
[Association("ProductPart", "id", "ParentID")]
public IEnumerable<WorksOrderTree> Children { get; set; }
[Association("ProductPart", "ParentID", "id", IsForeignKey = true)]
public WorksOrderTree Parent { get; set; }
public int ParentID { get; set; }
This gives the following error
Error 1
f0rmoum1..csdl(26,6) : error 0113: Multiplicity is not valid in Role 'WorksOrderTree' in relationship 'ProductPart'. Because all the properties in the Dependent Role are nullable, multiplicity of the Principal Role must be '0..1'.
Any idea to to how create zero-one to many in the ria service.
Thanks
Steve

Thanks for your reply Paul.
Yes I read your blog about the Telerik treeview and it was very helpful. the problem is that I want to use the Telerik RadTreeListView control instead, and It seem that it cannot be used with LightSwitch (for threading problems...)
So I am obliged to create a RIAService ( that I hope) it can return a hierarchical structure without any lazy loading, so the RadTreeListView can work....
but It seem that RIAService (Or LightSwitch) Insists on lazy load, and I don't know how to avoid it...
I know that I can create a service in my UserControl project as you say in your blog but I am trying to create a LightSwitch extention ....

EnsureVisible in TreeView: how to ensure that horiz. scrollbar is aligned left

Hi,
I have a tree view with eg. following nodes
# People
|
+--# Custumers
|
+-- # Anne Charles, Hillroad 14, 7766 MyTown, My Country
|
+-- # Steve Jones, Forestroad 12, 7766 MyTown, My Country
With the command
Me.treeViewM.Nodes(0).Nodes(0).Nodes(0).EnsureVisible()
I can ensure that "Anne Charles" is visible within the treeview. My problem is: If the treeview is not wide enough to show the complete node text of this node, the horizontal scroll bar is automatically moved to the right so that node structure shown left from the "A" in the text "Anne Charles" is not visible any more. Thus
Anne Charles, Hillroad 14, 7766 MyTown, My Country
Steve Jones, Forestroad 12, 7766 MyTown, My Country
is visible and the node structure is hidden.
Question: How can I ensure that the node "Anne Charles" is visible and also the horizontal scrollbar is aligned to the left, which means that the node structure left from the text is still visible?
Best wishes

Look at following code project also: http://www.codeproject.com/KB/tree/NoScrollingTree.aspx
You need PInvoke.
At Top
Imports System.Runtime.InteropServices
And Following Functtion
 Private Const WM_HSCROLL As Integer = 276
 Private Const SB_LEFT As Integer = 6
 <DllImport("user32.dll")> _
 Private Shared Function SendMessage(ByVal hWnd As IntPtr, ByVal wMsg As Integer, ByVal wParam As Integer, ByVal lParam As Integer) As Integer
 End Function
After Ensure Visible call the above Function
 Me.treeViewM.Nodes(0).Nodes(0).Nodes(0).EnsureVisible()
 SendMessage(treeViewM.Handle, WM_HSCROLL, SB_LEFT, 0)
