Show Item Text When Dragging A Treeview Node
Does anybody know how when dragging a treeview node, to display the text property of the node as well as the DragIcon. I want to be able to replate the drag drop behaviour of Windows Explorer, i.e while you are dragging a folder, you can see the folder name in transparent text.
I have no problem setting the DragIcon property from an imageList I have associated with the treeview. For example in the DragOver event I am setting the DragIcon based on whether the mouse is over a valid drop point. E.g. .DragIcon = LoadResPicture("NoDrop", vbResCursor)
However it only shows the DragIcon and nothing else when dragging the node. Any help appreciated.

Treeview - How To Drag A Node Item To Another Node Group
I have a program that im making, which has a treeview control. Ive got everything finished BUT, i need to make it so that the user can grad a node from one group, to a different group, and have it actually be placed in the group where it is dropped. Think of it like your lnstant Messenger buddy list.
Buddies:
User1
User2
User3 <--
User5 <-- The user should be able to drop "User4" between there.
User6
Family:
User7
User8
User4 <-- The user needs to be able to drag and drop this node to the
User9 "Buddies" group above.
I hope that little diagram thing helped explain what im trying to achieve. Ive played around with this for a bit, but i just started working with the treeview control so im not very familiar with it, also, ive never done anything with a drag/drop effect before. However, ive looked around the forum and ive found how to drag a node to another item in the form, like a textbox or something.
I really need help with this and it would be realllly appreciated if someone could help me get it to work. Thanks.
TreeView - Dragging And Dropping A Node In The Middle Of A Level
Does anyone know how to drag and drop a node within a treeview control in the middle of a level on the same treeview control?
When I use the drag and drop methods, and drop my node on a level I can drop it as the first child under that level or I can drop it as the first node at the same level.
IfI have 5 nodes under a level and want to drop another node in between nodes 3 and 4, it will only drop it before node 1.
Does anyone out there have any codes samples that they are using themselves to do this?
I have search the internet for samples and can not find one that does this.
Need Help Debugging Memory Leak Using APIs To View Treeview Node While Dragging
Hi all,
A long time VB hacker here.
This code is actually working with the first 7 drag and drops but stops working properly on the 8th attempt.
This is the least amount of code I've been able to find to:
View Treeview Node While Dragging.
AND works (well, kind of..) with mscomctl.ocx (v6)
I'm using Microsoft Windows Common Controls 6.0
in VB6 with SP5.
Any help in sorting this problem out and maybe cleaning this code up would be greatly appreciated.
Hopefully, other contributors will find this usefull as well.
Thanks,
Barry G. Sumpter

How To Locate A Node Item In Treeview?
Hi. I want to locate a node in treeview in runtime.
In listview, we can use:
lvdpur.SelectedItem=lvdpur.ListItems(i)
or in combobox, we can use Listindex.
but in treeview, no Listitems or Listindex can be used. So how to locate a node?

Select Treeview Node - Find In Db - Show In Listview
i use VB6, SQL SERVER 2k
i have a treeview with is populated from 3 tables using the code below
when i select a node i would like to feed a listbox with the appropriate data.
how can i find the correct record in the correct table in the db
when the node is selected.
all i can think of is by using the node.key but through my code i dont think this would be pretty much helpful.
is there a better way to populate my treeview, or a way to find the proper record in the proper table in the db?
Code:
' Add Node objects.
Dim nodX As Node ' Declare Node variable.
'root node
Set nodX = TreeView1.Nodes.Add(, , "root", "App.ProductName")
'tree structure
Set nodX = TreeView1.Nodes.Add("root", tvwChild, "child1", "Types")
Set rs2 = New ADODB.Recordset
rs2.Open "SELECT * FROM DevType", cn, adOpenKeyset, adLockOptimistic, adCmdText
'if types exist add them to structure
If rs2.RecordCount > 0 Then
Dim i
i = 1
rs2.MoveFirst
Do Until rs2.EOF
Set nodX = TreeView1.Nodes.Add("child1", tvwChild, "child1-" & i, rs2!Name)
Set rs3 = New ADODB.Recordset
rs3.Open "SELECT AppName,ApplicationID FROM DevApplication WHERE ApplicationID = (SELECT DISTINCT ApplicationID FROM DevVersions WHERE TypeID = " & rs2!TypeID & ")", cn, adOpenKeyset, adLockOptimistic, adCmdText
'if applications exist add them
If rs3.RecordCount > 0 Then
Dim k
k = 1
rs3.MoveFirst
Do Until rs3.EOF
Set nodX = TreeView1.Nodes.Add("child1-" & i, tvwChild, "child1-" & i & "-" & k, rs3!AppName)
Set rs4 = New ADODB.Recordset
rs4.Open "SELECT Name FROM DevVersions WHERE ApplicationID =" & rs3!ApplicationID, cn, adOpenKeyset, adLockOptimistic, adCmdText
'if application has versions add them
If rs4.RecordCount > 0 Then
Dim e
e = 1
rs4.MoveFirst
Do Until rs4.EOF
Set nodX = TreeView1.Nodes.Add("child1-" & i & "-" & k, tvwChild, "child1-" & i & "-" & k & "-" & e, rs4!Name)
e = e + 1
rs4.MoveNext
Loop
End If
rs4.Close
Set rs4 = Nothing
k = k + 1
rs3.MoveNext
Loop
End If
rs3.Close
Set rs3 = Nothing
i = i + 1
rs2.MoveNext
Loop
End If
rs2.Close
Set rs2 = Nothing
the tables structures in short, are
1. applications (name,idz,etc)
2. Types (aka. application types)
3. Versions (which relates the above two.)

TreeView With Long Node Text
When I launch my application with a TreeView object in it, then load the nodes based on some data, some of the nodes have text that is larger than the frame the TreeView object is in. At first, when I 'hover' over those nodes, the full text appears, like a tooltip (which is what I want). But after the object loses focus, such as a message box, or change application, that 'feature' is gone, even when the focus is returned to the TreeView object the full text is just truncated and no 'hover' tip appears. I have found that removing the object and creating it again will bring back the 'hover' tip, but that is not acceptable. What do I need to do to get it back?

Edit Treeview Node Text
I am trying to edit the text of the parent node at then end of my formload. At the end it returns a number that I would like to be placed at the top, but I don't know it tell all the searching is done...
This is what I have:
Beg:
Set nodX = TreeView1.Nodes.Add(, , "u", "Total Profit: ", "FoldersOpen")
----Other code very long ---
end:
TreeView1.Node("u").Text = "Total Profit: " + FormatCurrency(TotalProfit)
I get a method or data member not found error
I am guessing it is talking about the .Node("u").text but I don't know what the name for the parent
How Do I Make TreeView Node Text Read-only?
I have a treeview on a form. However the user can still click on the node and the text becomes highlighted (like edit mode) and whatever is typed in now becomes the text of the node. How can I disable this?
Thanks

Treeview - (un)check All Children Node If Parent Node Is (un)checked
Hi guy,
I have a treeview where I want to automaticly checkuncheck all the children of a parent node when the parent node is checked/unchecked. For this purpose I thought up the following code:
Code:
Private Sub Treeview1_NodeCheck(ByVal CheckedNode As MSComctlLib.Node)
For Each Node In Treeview.Nodes
If Node.Parent = CheckedNode.Key Then
Node.Checked = CheckedNode.checked
End If
Next
End Sub
But this gives me an error saying : "Object Variable or blockvariable With not set" (I had to translate the error so maybe it could be slightly different in english)... I can't think of anything that is wrong in the code, and I can't find a codesnippet that tells me otherwise, so what is causing the error?

Menu Item Dragging
One facility that Windows provides with certain menus is the ability to drag and drop items in them to different positions so that the user can re-order them (see for instance the Favorites menu in Internet Explorer and the Programs menu in the Start menu). So what if you want to have this sort of facility in your VB application? Can it be done?
The answer is yes, although clearly it can't be done with native VB, and it does in fact require subclassing of two separate windows. The attached project provides a demonstration of how it can be done. It emulates the design used in Windows 98, which is to have a bar appear over the menu to show where the menu item being dragged will be dropped. I have not explored emulating the design used in Windows XP, which is to have a translucent copy of the menu item being dragged appear as a drag icon, but no doubt the technique to do this would be similar, if more advanced.
The stages to allowing menu item dragging and dropping are:
1. Subclass the form that contains the menus. You will need to be comfortable with the concept of subclassing in order to understand the project. If you're not, try this thread by John.
2. In the subclassing routine for the form (WindowProc of SubClassForm), set the menus to be ownerdrawn. Code for this is courtesy of Garrett Sever at EliteVB .
3. Obtain the hwnd of the menu window. This is NOT the same as the handle to the menu, which all APIs to do with menus seem to use. Instead it is the handle to a window that contains the menu. You could get this through looking for the WM_ENTERIDLE message in the form subclassing routine, which gives it to you, although I do it by waiting until the first item in the menu is drawn, and then finding it with FindWindow.
4. Subclass the menu window. This is the key to the whole thing. All of the following steps are carried out in the menu window subclassing routine (MWProc of SubClassMenuWindow). The form subclassing routine does not give you sufficient messages to provide for menu item dragging, so you have to do this.
5. When the left mouse button goes down on the menu (MWM_MOUSEDOWN, MWM_MOUSEDOWNWIN98 messages), record where it does.
6. If the mouse moves (MWM_MOUSEMOVE message) outside the drag rectangle without coming up, begin a drag operation. Get a device context for the menu window, and draw a bar onto that device context to show where the menu being dragged will be dropped if the user releases the left mouse button.
7. When the left mouse button comes up (MWM_MOUSEUP, MWM_MOUSEUPWIN98 messages), don't call the original window procedure. Instead, re-arrange the data which your menus represent, and cause the menu window to be refreshed by use of InvalidateRect. This allows the user to see the changes that he has made before the menu is dismissed.
And that's about it. It is complicated, and it is otherwise undocumented so far as I can see, but it does work. If you have any comments or find any bugs then please PM me.

How Can I Loopt Through Node And Add Add Node Text To Combos Avoiding Duplicates
Hi
I have
a treeview and 2 combo box cboMonth and cboYear

02/09/03 (dates node child)
03/10/03 (dates node child)
04/10/03 (dates node child)
I need a routine that loops through the nodeShow and adds all the months in the nodeShow to the cbomonth and all the years to cboyear (avoiding duplicates)
Has anybody done that?

Show Window Content While Dragging
This isn't much help, but it's GOT to be in the registry. I've looked
for about 15 minutes and can't find it, but every other thing in the
world is in there.
FWIW -- I couldn't find an API for it either.
If you CAN find the registry entry, it should be fairly simple to
save the value to a variable, change it to the mode that allows
the skimming, and re-set it after you're done.

Moving A Node From A Treeview To Another Treeview
I have created a program that displays 2 treeviews, let's call them treeview1 and treeview1. The content of the nodes are taken from 2 different xml files. I would just like to know how i can click, drag and drop a node from treeview1 to treeview2. thanks!
Dragging And Dropping Outside Of A Treeview
I am attempting to create an application where a treeview has a hierarchal display of data, and the user can drag any item from the treeview to a textbox which is used to create a script.
My problem is this:
Say the root node is currently selected. When the user grabs an item which is not the root node, and drags it to the textbox, the root node is the only thing that gets moved.
If the user first clicks on the item (going through all mouse_down, mouse_up and node_click events) and then clicks and drags, it works fine.
But I'd like it so that the user doen't have to click twice (dragging with the second click) to drag an item outside of the treeview.
If the user drags the item around inside the treeview, the newly clicked node remains selected. But drag it out of the treeview and BAM! The originally selected node becomes selected again.
Any thoughts?

Dragging Items In A Treeview Between Itself
I've got a tree view control in my application and i need to drag its children nodes between the parent nodes. I.e you can be able to change the parent node just by dragging a node from one parent node to anotehr. Is this possible to be done by native VB, or does it need some API involveD?
I've seen several applications using this functionality. Any idea how i can solve this problem?
Thanks!
Click Item In Listview Then Show That Item In Combo As Index = 0
Hi guys,
I have a listview (lvwUserPunchedOut) that is populated with records in a database (persons first name in one column and last name in the second column), what I am looking to do is if I select a persons name by clicking on it in the listview on frmMain, and then bring up frmSearchCriteria, i would like to show that selected name in the combobox as default (cboEmployee.ListIndex = 0) on frmSearchCriteria (the combobox is sorted = True and is also populated with first name and last name of the person)
How would this be done? Hope I make sense. Thanks in advance.
Stop Item Dragging/moving In ListView
Is there any way you can stop the user from moving the item position in a listview?? I need them to stay the same as i added them first by code, with them being fixed for the user and not allowing any movement of item position!
thanks!
XML Node As Treeview Node/Tag
Hi.
I'm looking to store a reference to an xml node in the Tag of a tree view node.
I can't store the actual text etc because the i need the to be able to edit the xml sub nodes in place.
I'm thinking a can store the the memory address (via ObjPtr) as the treeview node tag, but does anyone know to do the reverse (i.e. get object from a given memory address) ?

Dragging With The Treeview (not Very Hard, Honest)
i have a form with a treeview and listview that lets you drag items from the treeview to the listview. however, it should only let you drag child items from the treeview, so i have this code:
VB Code:
Private Sub tvwHeaders_MouseMove(Button As Integer, Shift As Integer, x As Single, y As Single) If (Button = vbLeftButton) Then If (tvwHeaders.SelectedItem.Parent Is Nothing) Then Exit Sub tvwHeaders.DragIcon = tvwHeaders.SelectedItem.CreateDragImage tvwHeaders.Drag vbBeginDrag End IfEnd Sub Private Sub lvwSubHeaders_DragDrop(Source As Control, x As Single, y As Single) On Error GoTo ErrHandler If (Source Is tvwHeaders) Then lvwSubHeaders.ListItems.Add , Source.SelectedItem.Key, Source.SelectedItem.Text, 1 End If Exit Sub ErrHandler: If (Err.Number = 35602) Then MsgBox "You have already included this list.", vbInformation, "Cannot Add List" End IfEnd Sub
if you click a child item, then click a parent item, release the mouse button, click again and drag, it won't let you move it (good). however, if you click a child item, release the mouse button, click a parent item (without releasing the mouse button) and drag, it'll drag the parent item (bad). if that makes any sense to you, is there any way i can prevent that?
Scroll The Treeview When Dragging And Dropping
The only information that I can find on scrolling a treeview when dragging and dropping a node is out on microsoft's support online - Article ID: Q177743
http://support.microsoft.com/suppor...s/q177/7/43.asp
The problem that I am having with is solution is that when the mouse button is released over an area other than the treeview area, it continues to scroll. It does not recognize that the mouse button has been released. It also continues to scroll is you drag it off the form, which microsoft applications do not do.
Does anyone have a fix for this or possibly a better solution?
Dragging Items In A Treeview In Itself (changing Locations)
I need to perform a drag-drop function on a treeview control in which the user can move items between different nodes of the tree.
I need to implement this functionality via dragand drop, so as to make it easy to interact. Is this possible? Do i need to go into detailed API or wiht native VB it is possible?
Any ideas? Thanks a lot ppl
Treeview: Dragging And DoubleClicking (harder Then It Sounds)
Hello,
I got a little problem wih my treeview. I want the user to be able to Drag some items and double click on some items. They both work,but the only problem is when you doubleclick on an item (should be quite fast and it doesn't always happens) then it look likes you want to drag what is quite annoying.
Is there anyone who could fix this??
Thanx in advance
Open Node && Close Already Open Node In TreeView!
Suppose my TreeView looks like this:
Code:
Asia
|_____India
|_____Mumbai
|_____Pakistan
|_____Karachi
|_____Japan
|_____Tokyo
|_____China
|_____Beijing
Assume that all the nodes are closed. I open India; Mumbai can be seen. Keeping India open, I then open Japan; Tokyo can be seen. What I want is when I open Japan, India which was already open should get closed i.e. at any time, only 1 node should remain open. How do I do this?

Getting First And Last Node In The Treeview
how can i get the first item (that appears to be first) or the last item in the treeview?
TreeView.Nodes(1) does not work, or treeview.nodes(treeview.nodes.count).
Because if i enter a node before 1, by doing Add and making it a tvwprvious relationship to it, the "first" node will still have index of 1, and the "new" node will not have 1!
how can it be done?
thanks!
