Remove The Checkboxes For The Root Nodes
Aug 13, 2010
I am writing a windows application in vb.net. I have a database that will eventually hold about 100-150 people. To make it easier to find the person you need, I want to be able to organize them into an expandable list with Sophomore, Junior, and Senior as headers. Treeview seems like exactly what I need except I need checkboxes on the students but not on the headers. Is there a way to remove the checkboxes for the root nodes but keep them for the child nodes or is there another control I can use to the same effect?

I have a 3 layer treeview and is using the code below. I am getting it to do the following,
1) If parent is checked, check all child nodes.
2 If just one child node is unchecked, uncheck parent node.
3) If all child nodes are checked, check parent node.
Code below only works for 2 layers. Would appreciate if you can guide me how to make it three. There are much information on treeview but most of them seems irrelevant =/ Will be great if you can show me a good guide on treeview control.
Private Sub TreeView1_AfterCheck(ByVal sender As Object, ByVal e As TreeViewEventArgs) Handles TreeView1.AfterCheck
RemoveHandler TreeView1.AfterCheck, AddressOf TreeView1_AfterCheck
For Each node As TreeNode In e.Node.Nodes
node.Checked = e.Node.Checked

I found some Win32 code to selectively remove CheckBoxes from nodes in a TreeView. I would like to know if there is another way to do this, since we would like to stay away from Win32. Will this work under Window 7?

Public mask As Integer
Public hItem As IntPtr

I have a listview which I am trying to remove the initial root node's indent. My problem seems to be that I can't even set the indent value of the treeview in it's properties lower than 19, and if I try something like:
TreeView2.Indent = 16
16 seems to be the lowest value that makes any visual change.

I have a ListView with the columns 'Name', 'Expected', 'Total', and I want to add another column saying 'Recount' at the end. The 'Recount' column will ideally have a checkbox only if the 'Expected' value is larger than the 'Total' value.
So far I have got the ListView with columns and can add a check box on the left hand side, but that check box is not under a column heading (though I can probably put another column with no values in there to work around that) and it is on all of the records.

I'm all new to this treeview business. I have a fixed treeview, very simple and basic. Only two levels, parent and child nodes. I just need two things out of this treeview.
1) If parent is checked, check all child nodes.
2) If just one child node is unchecked, uncheck parent node.
That's it! I've been looking for this for 30 mins and I cant find it. Maybe because my vb.net is old, it doesnt seem to be the same as others =/ I'm using vb.net 2003.

I have a treeview that is populated from a HDD folder collection. Its structure is similar to the following (however the structure is dynamic):
My Disk:
|
|--folder1(tag:folder)
| |--subfolder1(tag:folder)
[code]....
I call the sub as follows:
deleteNode(treeview1.Nodes(0).Nodes)
However, the above is not working properly. It deletes only some nodes and not all the targeted nodes.

OK, so I have the code to add a Child Node to a selected node in ta TreeView. The thing is, even if I select a child node to "add" to, it adds the new node to the parent of the selected child node.
I know why it does that: TreeView1.Nodes(TreeView1.SelectedNode.Index).Nodes.Add() adds to the first node. So how do I progamatically add to the child node I have selected, not it's parent node. I can't figure out the logic on how to accomplish this.
NOTE: There can be an infinite amount of child nodes.
UPDATE: I just found out that if I have a child node selected, TreeView1.SelectedNode.Index returns -1 since there is nothing selected in that first level. I'd have to use TreeView1.Nodes(0).SelectedNode.Index to get the proper index for the ChildNode. *sigh*

I have a website www.abc123.com. What would be the best way to determine when users attempt to access pages like[URL]..I've done some research and found that Request.PathInfo works quite well when the user visits www.abc123.com/Default.aspx/section1 but it does not work without having the Default.aspx portion included in the URL.
Right now all I get are 404 errors when attempting this with the built in IIS server in VS2k8 and on a published website. I'm using ASP.Net 3.5 and IIS 6 if those things matter.

I'm trying to copy the directories located on a root drive (J:) to another location (c:vagtilleder..)The problem is, the first folder isn't beeing copied.Example:
J:
ootfoldersubfolder1subfolder2
After the copy it should look like this at the destination:
c:vagtilleder..
ootfoldersubfolder1subfolder2
But for some reason, "rootfolder" is not created at the destination, making the destination look like this:
c:vagtilleder..subfolder1subfolder2
where the error is located? OS: Win XP Pro VB 2008 Express.
Dim copytardir As String
Dim copydestdir As String
copytardir = ("J:")
