I was making a treeview favorites for my browser and got this code, however, nothing happens on startup, like the treeview stays emty
Heres the code for the Load handler
If System.IO.File.Exists(FavFile) Then
Dim xdoc As New Xml.XmlDocument
[Code].....
the exact same code works for the orginal project, and I have the same xml document in the same subfolders for my project
How do I load the URLs of all favorites in the Favorites file and how do I make favourites in the file? This is the code I have:
Public Class Form1
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim favouriteFiles() As String = System.IO.Directory.GetFiles(Environment.GetFolderPath(Environment.SpecialFolder.Favorites), "*.url")
For Each currentFile As String In favouriteFiles

View 1 RepliesI am creating a web browser and I would love to be able to view IE favorites and add, delete, rename, and all that to them too.I want to be able to say add to favorites and a new form comes up saying url and name, in the favorites list it reads as the name but when you click it goes to the url. This is what I have so far, never even started the code because I don't know were to start.

3) Left Panel thats hides / shows
4) List Box that the name is Favorites
5) a combobox that has a go button, you could also press enter and no beep sound comes up
6) I got a tabcontrol web browser page

-Race
|-HQ
|-TROOP
|-ETC...
now... the program loads all units from xml. so when it encounters for instance a unit with a "<class>" tag containing HQ, how do i make it put it in the HQ node? I cant make it put new nodes into existing ones, only into new ones....

Parent

How would that look in a database? and then how would you load the tree. I can load everything up to the grandchild, but as soon as I load the great grandchild I start having issues. So I am thinking it is the way they are in the database.
I have a treeview control with check boxes. when I check the parent node, all the children check too. The problem is, I want the parent check box to automatically uncheck if one of the children is unchecked.

I have a treeview dragdrop event written in VS2003. It works perfectly fine when the application is running on desktop, until we move the application to Citrix. So, users are now running it off from Citrix, the DragDrop event doesn't work anymore. It doesn't even have the effects of allowing dropping.
View 3 RepliesI have created an object hierarchy with nested generic listof() structures. I have created a treeview to match and graphically show the structure. I needed a way to show a property box of an object represented by the selected node on the treeview. So, I gave each of my objects a NodeIndex property, in which I would store the treeview.indexof(node) result, as shown below:
For Each oObject In oJob.ObjectListOfCollection
tnode = New TreeNode(oObject.Name)
Treeview.Nodes.Add(tnode)

I have some code in VB.Net that I've been using for years that has been working fine, that is until I upgraded to Internet Explorer 9. The essence of code is below. In IE8 or earler, the code works. In IE9, when it tries to execute Br.Document.Body.innerText (or .innerHTML), I get an exception "Public member 'innerText' on type 'DBNULL' not found." When I add Br to the Watch window and hit + several times to get to inerText, it actually shows the text, but if I add Br.Document.Body.innerText to Watch, it returns DBNull as the value.Because of this problem, I removed IE9 and reverted back to IE8, and the code works fine. Of course, I would eventually prefer to upgrade to IE9, but this bug needs to be fixed first.

View 1 RepliesWhat would be the fastest way to put XML nodes in memory? I can use generics, arrays, list arrays and so on but how to get the nodes first? All of the following are taking too long:
XmlDocument.Load
XmlDataDocument (used it by accident)
XPath.XPathDocument("path")
I can loop through 500 000 Nodes and get the 30 000 uniques in less than a second instead of 3 hours previously but loading the nodes takes whole 20 seconds. Never thought this would be the bottleneck.

On click of that particular node, it displays text eventhough when I set BackColor as Black. Is there anyway to hide the text in Scenario also.
