Treeview - Capture Click Of Treeview Image
Hi,

I have a treeview where I am using the node image to mimic the functionality of a checkbox. Initially the node image (for topmost nodes only) is set to an image of an unchecked checkbox.

Is there any way to determine if the user clicks on the node image (and not the node text). I need to be able to alter the image from unchecked checkbox image to a checked checkbox image when the user clicks this image. However, I still want to allow the user to click the node text to expand/collapse the node as is the standard for this control.

Any help would be much appreciated.

TreeView - Want To Highlight Part Of TreeView
Hi, This must be a simple 1 line of code:

Have some VB code I didn't write, I am modifying it. Works OK but want to do one thing:-

The treeView has 1 branch called [NEW] A branch is inserted in and is highlighted (say called "hello"). I would like to set the highlight to the branch called "hello" not the original branch called [NEW].

The TreeView is called TVWizard.

I have used:-

TVWizard.setfocus

This sets the focus of the TreeView object. I somehow need to move the highlight to the "Hello" branch (node)

ONLY STARTED VB FEW WEEKS AGO, ANY HELP APPRECIATED

take it need something like TVWizard.Node("hello").focus = true ?????????

[VB6][TREEVIEW] How To Unchecked The Treeview Node
I would like to make a function for the user, when a user checked any of the parent node, the entire of child node and parent node will checked.
I tried to write on myself. The child node will checked if checked on parent node. However, i can't unchecked the child node if parent node unchecked.

Code:
Dim IndentifyCheck As Integer
Dim nodMP As Node
Dim nodP As Node
identifycheck = 0
If Node.Checked = True Then
If Not Node.Parent Is Nothing Then ' Parent exist.
Node.Parent.Checked = True
If Not Node.Parent.Parent Is Nothing Then
Node.Parent.Parent.Checked = True
End If

End If
If Not Node.Child Is Nothing Then
Set nodMP = Node.Child
Do Until nodMP Is Nothing
nodMP.Checked = True
If Not nodMP Is Nothing Then
Set nodP = nodMP.Child
Do Until nodP Is Nothing
nodP.Checked = True
Set nodP = nodP.Next
Loop

End If
Set nodMP = nodMP.Next
Loop

End If
Else
Do Until Node = Node.LastSibling
If Node.Checked Then
identifycheck = identifycheck + 1
End If
Set Node = Node.Next

If identifycheck < 1 Then
If Not Node.Parent Is Nothing Then
Node.Parent.Checked = False
If Not Node.Parent.Parent Is Nothing Then
Node.Parent.Parent.Checked = False
End If

Set nodP = nodMP.Child
Do Until nodP Is Nothing
nodP.Checked = False
Set nodP = nodP.Next
Loop

End If
Set nodMP = nodMP.Next
Loop

End If

Treeview And Hyperlink Inside Treeview
Hi
I want to use the treeview for Statistic purpose.First,the user chooses one Keyword(it's an author),and when he clicks on the OK command,the keyword appears with a + on its left,when the user clicks on the +,it appears a collection of all the books the choosen Keywords has written(the collection of the books is obtained by an SQL query:
Select * from authors where author like '" & sauthor & "'" and each book written by the author will be added to the list with a + on its left

The user clicks on the book he wants to view its detail(he clicks on +),so he should see the date of publication(also this date is obtained from an SQL),and when he clicks on the + on the left of the keyword,the title of the book should appear as a hyperlink,when the user clicks on the hyperlink,it should display the cover of the book which is saved as a jpg file in the local disk

Can anyone guide me through the steps to accomplish this project?

Thanks in advance

How To Copy Treeview To Treeview!?
Hi there,
I was wondering how I would go abouts in copying a treeview to another treeview? I've seen a few code on some websites, but they just do not work. I am not using a standard treeview, I am using the vbaccelerator treeview control.

Treeview Control Without Imagelist/using System Imagelist In Treeview
I am reposting this here because I didn't get a response in the VB 5/6 forum. The getfileinfo api function returns the system imagelist (?) and index to the files icon. Is there a way of using this list and index in the treeview control ? Any help would be appreciated

I am writing an applicatiion that simulates explorer using the treeview control. I've been able to extract the icon from a file using the WinApi but have not found an example where I can use a picture without an imagelist. Its impractical to add all the files on a system to an image list.

Is there a way to do this ?

Thanks,

TreeView Bug
Hi,

I have a big problem with a TreeView, due a Bug (I think)

I'm using a TreeView with checkboxes to show all permissions of the program, Example: Window1 -> Add, Edit, Delete , Query, and there for all windows, well my Fill TreeView routine is working well, all its fine, while the TreeView doesn't have assigned a ListImage Control, when I assing a ListImage control to the TVW the checkboxes always are unchecked even my routine checked them.

The way of calling the Fill TreeView routine its this one:

From Window where Users of the program are enumerated:

Code:
Private Sub lvwUsers_DblClick
......

Load frmPermissions
frmPermission.LoadUser (<Selected User Index>)
frmPermission.Show
......
End Sub

Code in the LoadUser into frmPermissions

Code:
Public Sub LoadUser
FillPermissionsTree (Works fine)
....
.....

'Here Starts my routine where only the permissions that have assigned the user are checked

For I = 1 to tvwPermission.Nodes.Count
If <Condition> Then
tvwPermission.Nodes(I).Checked = True
Exit For
End If
Next I

End Sub

Thats my way of doing this, I think nothing is bad in this routine.

Well, I hope make sense this post, Thanks

Treeview
alright, i know this question as been asked before, but there was no answer, so i try again.
i have a window with two frames: on the left side a frame with a treeview in it, on the right side a frame which will show the appropiate info, belonging to a 'clicked' item in the treeview.

the problem was that loading the data in the treeview (from a database) takes a lot of time. so: i managed to decrease the loading time considerebly, by only loading the first 2 levels of the tree, the rest is being loaded on a nodeclick event, and for algortithmic purposes, when u click on say, level 2, it loads untill level 4 (so 2 in one). (has to do with my database, it's kinda complicated)

but: and here's the problem: when a user doubleclicks on an item from the tree, it should be (vb does that itself, normal behavore) like a nodeclick event, and expand a level....

it doesn't do that: it skips some data to be loaded, not much, but some. does anybody have a clue how to fix this, -or- disable the doubleclick thing?

thanx!

Treeview
I have a treeview control that displays all the information stored in my program. What I need to do rebuild the tree structure without collapsing the entire structure. Is there a way of storing which trees are open and which item is currently selected, (then clear and rebuild the tree) and finally restoring this state at a later time?

Also, if anyone knows how to simply expand a certain tree this would be useful and might help me figure out the rest.

Thank-you.

TreeView Help
Hi,

I'm a newbie developing an app in VB 6- I've got a treeview control that I am struggling with....

The scenario is this. When the user clicks on one of the node objects, I want text detail to appear in a textbox to the right of the control. I've gotten this to work, but when I click on any area in the control that is NOT on a node, I get the following error: "Object Variable or With block variable not set".

My code for the Mousedown action looks like this(where the error is coming from) -

Any help would be appreciated....

TreeView
Hello,

I've built an application where I can show the information from a database.
I will use a TreeView where I can show the orders of my table and the suborders of my table.
I tried to make this and it works. But I have a small question about the properties for the treeview. In a textbox you have the propertie "Mulitline" to show more line information. Now in my suborders I need to show also more than 1 line. Is there a possibilitie to do this, because now I only see a part of my information in the treeview?
Is it also possible to change the backcolor and forecolor?

Br, Peter.

1. How can I check if an item with a certain Key exists in a treeview control?
I tried:

Code:
If tvwDirList.Nodes.Item(sKey) Is Nothing Then
'
End If
but got an error saying 'Element not found'. I realize I can use it with error trapping but I'd rather not...

2. I'm trying to create some sort of explorer and I want it to look like the one in the attachment.
My problem is with the items marked with a red dot. How can I scan for them?
Obviously Dir$ wouldn't help...

Treeview
Im looking to make a treeview based file manager system that will allow files to be viewed from another machine. I have a server client system set up already, and have started working on the treeview interface before i try and update the information remotely. I searched out a tutorial on how to do it, and came across this site...

http://abstractvb.com/code.asp?F=49&P=2&A=716

I seem to be having problems getting the code to work, i believe its because of this line...

Set foNode = TreeView1.Nodes.Add(parent, tvwChild, ,_
folder.Name, "ClosedFolder")

this appears in a strange format as it is seperated and put on two lines, plus underscore is not used in vb6...

anyone tried this and have been successful in getting it to work? im also looking for links for info on how to remotely update the information... any help appreciated, cheers.

Treeview
Hi.

Somehow I'm having problems with the treeview.
If I use the code below, I get the following error (on the 2nd line):
'invalid object'

Code:
Set mNode = tvwKlanten.Nodes.Add("Klanten", tvwChild, rsSpecificatie!klantnaam, rsSpecificatie!klantnaam)
Set mNode = tvwKlanten.Nodes.Add(rsSpecificatie!klantnaam, tvwChild, "", rsSpecificatie![iso-nummer])

If I change the 2nd line like this:

Code:
Set mNode = tvwKlanten.Nodes.Add("Klanten", tvwChild, rsSpecificatie!klantnaam, rsSpecificatie!klantnaam)
Set mNode = tvwKlanten.Nodes.Add("--", "", rsSpecificatie![iso-nummer])
It works. The value of the rsSpecificatie!klantnaam is "--". Somehow it I link to the the recordset it just doesn't work.

Any suggestions?

B.R.

Is there an easy way to copy the contents from one TreeView to another?

Treeview Help !
just a few questions to be honest. But the main one is the treeview issue, this is related to API, i probably should have put this in API Category, anyway...

I have a business application that i wish to add additional nodes to its treeview using API.

This business app is not written in VB nor do i have the source code, i know for sure its just using standard treeview because i can use standard treeview api calls on it (for example : TVM_GETITEM )

Whats the api to add new nodes to a treeview? i need some examples in vb if possible (posting code will be fine)

The other question i had was using appendmenu how do i add new menu items to existing menus within an app (the business application again)? i only know about CreateNewPopup...

One of the menus i wish to add new items to is actually a popup when you right click on a listview the menu appears.

Thats all for now...

thanks in advance,

About The Treeview
Hi all,

I am currently using the treeview control for a program.

The problem is that when a node if the tree contains a text that is too long in regard of the tree's width, a yellow box appears to display the whole text when I put my mouse on this specifis line.

I find this extremely annoying and I would like to avoid that.

Is there a way to do that???

Thanks for advance.

Treeview ?
I have treeview with 3 parent nodes each of the parent nodes have children with their own children etc. I came up with a routine that will allow a user to show only the child node of a parent that they select. i.e. all other child nodes are removed from that parent node. I would like to be able to do this for the parent nodes also. That is if a user highlights parent node 1 then parent nodes 2 and 3 are removed. I thought that filtering the parent nodes would be easy but I cannot seem to figure out how to do this. Any ideas?

Treeview From DB
Hello again!

I'm trying to populate my Treeview from DB. It works good except Child nodes. The problem is, that I want to populate it like this:

Table name: URL
Fields: Kategorija, Podkategorija

Private Sub vpisi_treeview()

Set rs = db.OpenRecordset("SELECT DISTINCT Kategorija FROM URL", dbOpenSnapshot)
If Not rs.EOF And Not rs.BOF Then
With rs
.MoveFirst
Do Until .EOF
Set vozel = TV1.Nodes.Add(, , , !Kategorija)
vozel.Image = 1
Set rs1 = db.OpenRecordset("SELECT DISTINCT Podkategorija FROM URL WHERE Kategorija = '" & !Kategorija & "'", dbOpenDynaset)
With rs1
.MoveFirst
Do Until .EOF
If Not IsNull(!Podkategorija) Then
Set vozel = TV1.Nodes.Add(1, tvwChild, , !Podkategorija)
End If
.MoveNext
Loop
End With
rs1.Close
.MoveNext
Loop
End With
End If

End Sub

Where "Kategorija" = Databases, Text, Forms & controls etc, and "Podkategorija" = DAO, ADO, Compare string, Arrays, etc (Like: Kategorija = Databases, Podkategorija = DAO or ADO...)

What is going on here is that Child nodes don't appear under the right (parent) node but under the first node in the Treeview (All of them).

How can I do this the right way?

Regards!
