ActiveX Tree Control

Hello group,
I want to use an ActiveX Tree Control in my application (LabVIEW 6.1). How
can be secured that the built application will run on any 32Bit Windows
system? I. e. which ActiveX Server must be installed, what is the most
common type and where can I get the package from?
Thanks,
Marko

Marko,
Microsoft ActiveX TreeView control is part of the Microsoft Common controls. As long as you have the mscomctl.ocx installed and registerd on the machine, you will have the TreeView control, and will be able to use the LabVIEW built executable that uses this control.

Tree Control ActiveX and the Runtime - help...

We've build a BridgeView application that lets you select past datasets
using a tree control. It works fine when the BV development system is
installed, but when we remove it and replace it with a Run-time
version, the control is no longer visible or active....
TIA,

Share what you know. Learn what you don't.

Thanks for your answer. Unfortunately I am stuck to Labview 7.1 for other reasons and the defer front panel updates only improves my numbers by a 30% which is not enough as already mentioned by the post you refer to. Sadly enough the 'add multiple items' method is not available for the same string control in Labview 7.1. Maybe I should investigate further in the Active X area...

Add multiple elements to a tree control at once

I am using a Tree Control to display customer and certificate information. However, adding 500 customer names or certificate numbers to the tree control one at a time takes for ever (well, 30000 ms). Is there any way to add multiple elements to a tree all at once, or is the only solution to use a listbox with 'forward' and 'back' buttons ?
thanks,
michael

Hi Michael
I don’t believe there is a way to supply a list of child items to a parent item, they have to be added incrementally. One way that you could speed this process up is to design your code such that only when you expand an item does it add the child items.
If you want an even higher update rate have a look at using the ActiveX TreeView control, you will find an example called Family Tree.vi in the LV examples.
I'll do up some code that makes using both of the controls more efficient if enough people want it.

How can I display and change built-in symbols of a tree control programmatically?

I want to set the built-in symbols of a tree control during runtime.
I only found an example to assign custom pictures but not how to select one of the 40 built-in symbol.
Many Thanks
Solved!
Go to Solution.

The ActiveItem.SymbolIndex will allow you to select the symbol for the active item. You can use the ListBox Symbol Ring Constant (Dialog and User Interface palette) to select a symbol (or you can just enter the number directly if you know what it is).

Not able to get the database data into the Tree Control

Hi Everybody,
I have to populate the tree control with nodes and items, which is to be populated from the database, and the tree control is dynamic. I mean, there is a toolbar, whenever a pushbutton is clicked, depending on that the tree contents has to be changed.
If anybody had worked with CL_GUI_COLUMN_TREE control to get the data from database, depending upon the pushbutton selected in Toolbar, please paste the seudocode for it.

How to get all items under a parent item in a tree control

Hello,
I have 2 questions regarding a tree control:
1) Is there any way to specify a parent item tag and get an array of ALL its sub item tags? For example, in the attached vi, specify the Parent#2 parent tag and get an array containing Item#P21 and Item#P22
2) Is there a way to specify a range to the ActiveCell property. For example, all items from line#1 to line number#3
Any ideas?

Did you try a search? There's no direct way of doing this. You have to navigate the tree and build up an array. You can find an example here: http://forums.ni.com/t5/LabVIEW/get-all-children-of-a-parent-in-tree/td-p/729548
2) Is there a way to specify a range to the ActiveCell property. For example, all items from line#1 to line number#3
No. (It's called ActiveCell, not ActiveCells) Presumably you are trying to perform an operation on multiple items. Unfortunately, you need to use a loop. You should defer panel updates if you're doing this a lot.

How to binding incoming xml node list to the tree control as dataProvider

Recently, I faced into one issue: I want to binding incoming xml node (it's not avaliable at start) list to the tree control as a dataProvider.
Since the incoming xml node list is not avaliable at beginning but I needs to bind it to the tree, so I create one virtual one in the xml, and prepare to remove it before the tree is shown. (ready for the actual node adding). But It did not work.
Please see the presudo-code here:
1. Model layer(CsModel.as)
public class CsModel
 [Bindable]
 public var treeXML:XML=<nodes><car label="virtualOne" id="1">
 </car></nodes>;
 (Here, I want to build binding relationship on the <car/> node,
 one 'virtual/stub' node is set here with lable="virtualOne".
 But this node will be deleted after IdTree
 control is created completely.)
 [Bindable]
 public var treeData:XMLList =new XMLListCollection(treeXML.car);
2. view layer(treePage.mxml)
 private var _model:CsModel = new CsModel();
 private function addNode():void
 var newNode:XML=<car/>;
 newNode.@label="newOne";
 newNode.@id=1;
 _model.treeXML.appendChild(newNode);
 private function cleanData():void
 delete _model.treeXML.car;
 <mx:VBox height="100%" width="100%">
 <mx:Button label="AddNode" click="addNode()" />
 <mx:Tree id="IdTree" labelField="@label"
 creationComplete="cleanData()"
 dataProvider="{_model}"/>
 </mx:VBox>
3. Top view layer (App.Mxml)
<mx:application>
 <treePage />
</mx:application>
For method: cleanData()，It's expected that when the treePage is shown, we first delete the virutalOne to provide one 'clear' tree since we don't want show virtualOne to the user. The virutalOne node just for building the relationship between treeData and treeXML at beginning. But the side effect of this method, I found, is that the relationship between treeXML and treeData was cut off. And this leads to that when I added new node (by click the 'addNode' button) to the xmlXML, the xmlData was not affected at all !
So Is there any other way to solve this issue or bind the incoming xml node list to the xmlListCollection which will be used as Tree control's dataProvider ?

If u want to display the name : value then u can do like this
<xsl:eval>this.selectSingleNode("name").nodeName</xsl:eval> : <xsl:value-of select="name" />

How can I save the all the values of a tree control ?

I have a problem, in run time, I adds new items on a tree control, but i don´t know how I can save the values of the child text of each item in a file.
Thanks.

I'm no expert on the tree control, but I made a small example to save all items to a textfile, including item tag, item string, and indent level. One drawback of this method is that it fully expands the tree regardless how the user left it. To go the other direction, you'd have to write a routine to go through the text file and programmatically build the tree.
To master the tree control, I think you have to resort to creating a control reference for it and using the Invoke Node to do some operations. For another approach to traversing and operating on a tree, check out the "Traversing Tree Controls and Setting Custom Symbols" (search the NI Developer Zone site).
Best of luck,
John

How can I drag and drop an item from one Tree control to another in LabVIEW 7.1?

You can use the mouse up and down event on the two tree controls but the problem is making the correct selection in the second tree control. I want to be able to switch over to the selection bar of the second tree control so that I can place my item in the correct position. I know all possible workarounds with double-clicks and so on... but I really want a windows drag and drop.
This is what I have for the moment. Please check the library below. I need to activate the selection bar of the second tree control somehow to get the position in the control. The VI below is written in LV 7.1

Drag&Drop.llb ‏65 KB

Hi Jones,
As far as I know this feature is currently not supported by the Tree control. A workaround, would be to use the vertical position of the mouse in the button up event to determine what line you�re dropping the item.
If you would like the Tree control to include the drag and drop feature, please submit this as a Product Suggestion under the feedback at www.ni.com/contact.
Good luck!

How to use the drop event of the tree control in LabVIEW 8.20?

Hi,
I am using the two tree controls in my application to provide a option for the user to drag and drop item from one tree to the other. I have to validate the user selection. I tried to capture the user drop event using the event structure. The problem I am facing is, I am not able to drop the item even though i have wired a constant true to the filter(Accepted?) in the event case. I have enable the property(Allow droping) in the right menu of the tree control also.
While configuring an event case for (drop, drag entered and some thing like this) only I am getting the problem otherwise it is working fine.
What do i need to do to caprture the drop event ?
Is there any way to avoid the item duplication while droping a new item in the tree control ?
or how can i do this?
Thanks,
Pandiarajan R

Hi Pandiarajan,
I hope you are doing well today! There is a lengthy discussion on the Tree Control Drag & Drop feature at this forums post including contributions from the developer of the Drag & Drop feature:
Tree Control Drag & Drop in LabVIEW 8
By avoiding item duplication, do you mean that you don't want the same item to be in the old tree control or do you not want more than one item in the new tree control?

How to get position of a ring in a tree control?

Ok, this is probably a stupid question, but how does one get the position of a ring inside of a tree control? I have a tree with two columns, with rings in the second column. I can set the position using SetTreeCellRingValueFromIndex(), but how does one get the position after the user has modified the control? I found the functions GetTreeCellRingIndexFromValue() and GetTreeCellRingValueFromIndex() but I haven't found a way to get either the Index or the Value of the ring (what I'm looking for is the index, but if I can obtain the value I can go from there). Thanks in advance!
Solved!
Go to Solution.

Hi,
You can use GetTableCellVal function to get the value of the ring.
There is not special "ring" function for that. Maybe that's what you were searching for
From the value you can get to the index using the functions you are already aware of.
Hope this helps,

How do I get the tag of a selected line in a tree control ?

I am running LabVIEW 7.1.
I want to be able to add a parent or sibling to a tree to a selected item in a tree.

The tag of the selected item is actually the output of the tree control itself. If you create an indicator from the tree control, you will get a duplicate tree control (indicator), but if you wire the output into a string indicator, the tag of the selected item will show up. You can an item to the tree by wiring the tree reference into an invoke node, calling the method "Edit Tree Items: Add Item", and wiring the output of the tree control (which will be the tag of the selected item) into the "Parent Tag" terminal. This method will only let you add a child to an item, you cannot add a parent or sibling. Items cannot have multiple parents, so it wouldn't make sense to add a parent; and to add a sibling for the selected item, you could call the method "Navigate Tree: Get Parent" and pass the tag of the parent into the "Edit Tree Items: Add Item" method.

Tree control - How to get the full path of selected Item in tree control

I am Flex newbie. When the user clicks the particular item in
the tree control I just wanted to get it name along with it's full
parent.
Here is my XML
var dirXML:XML=<root basename="/home/tcegrid">
<Directories>
<Dir Name=".autosave" />
<Dir Name=".emacs.d" />
<Dir Name="AnsysDistributed">
<Dir Name="opt"/>
<Dir Name="root" />
</Dir>
<Dir Name="postgres"/>
<Dir Name="FineTurbo"/>
<Directories>
</root>
The above XML is data provider for Tree control. When the
user clicks the Dir Name called opt. I wanted it absolute path in
XML. say Directories.Dir.Dir.@Name is opt
Can any one tell me how to get this?

How to render image in tree control without embed it

Hello frndz i am working on tree control and want to show imagein its node through xml list collection.i have searched a lot for this but in every example with tree control images are embeded.i dont want to hardcode the image.Need to make the image comes from database(Xml).so is there any live or demo example for tree control.
Thanks in Advance
Vineet osho

if you decompile the imaging.ear file, there is a web.xml file which you can add the following parameter:
<context-param>
<param-name>oracle.adf.view.rich.security.FRAME_BUSTING</param-name>
<param-value>never</param-value>
</context-param>
or take a look at Receiving "Warning: Unable to load content in a frame. Frame content will load at the top level." When Trying to Use the <af:inlineFrame> Component [ID 1266770.1] on Oracle Support.
Make sure you take a copy of the imaging app before you make changes. You can then upload back through the weblogic console.

VB ActiveX User Control fails to install on Windows 8 using IE10 with Code Download Error: (hr = 80070005) Access is denied.

I have a VB VS2008 (.Net 2.0) ‘pure’ .NET based user control which used to be hosted in Internet Explorer.
Because that approach is no longer possible in VS2013 (.Net 4.5) I have converted it to an VB ActiveX user control.
This process involves digitally signing the user control DLL.
Creating a setup project resulting in a setup.exe and MyUserControl.msi.
Digitally signing both those components and then producing a cab file (which again is digitally signed).
IE10 should then be able to install this using an object tag as follows
<object id="editor" height="100%" width="100%"
classid="clsid:EA47DB16-9272-4CB3-A800-C369A479396A" codebase="cab\MyUserControl.cab#Version=6,0,11,1" VIEWASTEXT>
If I use the setup.exe and MyUserControl.msi directly on the client windows 8 machine before starting IE10 then the control is already installed (shows up in Programs and Features) and it works.
If I don't do this and let IE install the control then it doesn't work.
What I see is the IE prompt
This website wants to install the following add-on: 'MyUserControl.cab'
Clicking on install produces the User Account Control MsgBox
Do you want to allow the following program to make changes to this computer
Clicking yes doesn't install the control as expected
The inf file that I'm using is currently
[version]
signature="$CHICAGO$"
AdvancedINF=2.0
[Add.Code]
setup.exe=setup.exe
MyUserControlSetup.inf=MyUserControlSetup.inf
MyUserControlSetup.msi=MyUserControlSetup.msi
[setup.exe]
file=thiscab
[MyUserControlSetup.inf]
file=thiscab
[MyUserControlSetup.msi]
file=thiscab
[Setup Hooks]
RunSetup=RunSetup
[Deployment]
InstallScope=user
[RunSetup]
run="%EXTRACT_DIR%\setup.exe"
I have defined the registry setting ForceCodeDownloadLog
Examining the temporary internet files location after trying to install using IE10 I can see the following
*** Code Download Log entry (15 Jan 2015 @ 11:49:18) ***
Code Download Error: (hr = 80070005) Access is denied.
ERR: Run Setup Hook: Failed Error Code:(hr) = 80070005, processing: %EXTRACT_DIR%\setup.exe
LOG: Reporting Code Download Completion: (hr:80070005 (FAILED), CLASSID: ea47db16...,

The problem here was the cab file.
Using ProcessMonitor I found that the following entry was generated at the time of failure
16:48:00.9222751 2920 IEInstal.exe CreateFile
C:\Users\Jim\AppData\Local\Temp\IDC2.tmp\setup.exe NAME NOT FOUND Desired Access: Read Attributes, Read
Control, Synchronize, Dis, Options: Synchronous IO Non-Alert, Non-Directory File, Disallow Exclusive, Attributes: n/a, ShareMode: None, AllocationSize: n/a
Analysis of the contents of the cab file using PeaZip indicated that it didn't contain setup.exe which confused me for a while as the makecab /f MyUserControlSetup.ddf produced no errors.
The MyUserControlSetup.ddf contained
.Set DiskDirectoryTemplate=cab
.Set CabinetNameTemplate=DocEditor.cab
MyUserControlSetup.inf
MyUserControlSetup.msi
setup.exe
Using makecab /f MyUserControlSetup.ddf /v3 I saw that the output was being written to 3 'disk' files but only one was present in explorer after it finished.
So I guessed that the output was for floppy disks and changed MyUserControlSetup.ddf to contain
.Set MaxDiskSize=CDROM
.Set DiskDirectoryTemplate=cab
.Set CabinetNameTemplate=DocEditor.cab
MyUserControlSetup.inf
MyUserControlSetup.msi
setup.exe
PeaZip now indicated that the cab file contained the 3 files I expected and using that cab in the codebase attribute installed my ActiveX control
