From the reference you have given that is actually creating a custom tree view control from what i understood. But what I need is:
I cannot create a tree data structure because I have to read the xml first and store in some collection.
I have a user control where I have: a picture box control and tree view control below that. When the picture box is clicked I want to show the treeview with nodes and sub nodes if any looping through the collection. Any examples of this kind please.
Thanks for your help in advance !

I don't know if I understood this properly, but as you want to loop through your XMLDocument and placing the items into a TreeView, you can try the following. MainTree is the TreeNode and doc is the XMLdocument.
Dim doc As New XmlDocument<br />
doc.Load(PathName)<br />
MainTree.Nodes.Clear()<br />
For Each mainroot As XmlNode In doc.ChildNodes<br />
Dim maintreenode As New TreeNode<br />
maintreenode.Text = mainroot.Name<br />
MainTree.Nodes.Add(maintreenode)<br />
For Each subnode As XmlNode In mainroot.ChildNodes<br />
Dim subroot As New TreeNode<br />
subroot.Text = subnode.Name<br />
maintreenode.Nodes.Add(subroot)<br />
<br />
etc..<br />
<br />
Next<br />
Next<br />
Hope this helps you out,

Ähm, no. Its a Tree-Datastructure, no Control. And I build a Tree from it, which each leafs type String.
Why cant u create a similar tree datastructure ("Value" can be any type, so I suppose, also the datatype u need), and fill it by reading the xml?
And from that tree build ur UserControl-Treeview, and do the other things, u want to do.

This is a silly question, but is there a way to get datagridview columns names in intelli-sense as properties?
For example:
grdUsers.Rows(vlngUserRow).Cells("SoftwareSystemSecurityID").Value
Is it possible to do something like (property vs. having to type the column name)?
grdUsers.Rows(vlngUserRow).Cells.SoftwareSystemSecurityID.Value
Thanks for any help/suggestions!

If you added the column at design time, you could reference it like this:
grdUsers.Rows(vlngUserRow).Cells(SoftwareSystemSecurityID.Index).Value
But if you get the column because you had set the grid's datasource to a dataset/datatable that contains the column, this doesn't work.
Hope this helps.

There are 2 list box and a horizontal Splitter. When I resize the window, both the listbox does not resize proportionally. The top listbox remains in same height, the bottom listbox gets resized.
The properties for splitter is
cursor - HSplit
Dock - Top
The properties for listbox1 is
Dock - Top
Anchor - Top,Left
The properties for listbox2 is
Dock - Fill
Anchor - Top,Left
Changing the dock or Anchor do not work out..

Hi,
Since the Dock property is set to Top, the width will resize in proportion to the window size.
Therefore, in order to get the desired resolution try setting the Dock property of first ListBox to Fill. This will ensure that the ListBox resizes proportionally to the window.
Hope this helps .

I tried that option too.
If both the listbox is set to Fill, then i can able to view only one list box.
This option is not working

You can write practically any SQL into the SqlCommand object. All you need to do is write the SQL to perform the back up and perform ExecuteNonQuery() on the SqlCommand object.

Hi, I am now working on a data compare and copy for datagrid. Below i have the codes the open up this csv file and attached it to the datagrid1.
I am now finding a way to
1. Type in "123123" into the textbox
2. Click a button
3. Compare it with the datagrid1(which has the opened csv file) or compare directly with csv file
4. Copy the whole row on which the "123123" is found and paste into another field or datagrid for display
Public Function Import()<br />
<br />
Dim myPath As String = "c:\testing.csv"<br />
<br />
Try<br />
<br />
Dim objDataSet As System.Data.DataSet<br />
Dim objAdapter As System.Data.OleDb.OleDbDataAdapter<br />
<br />
strConnection = New System.Data.OleDb.OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0; Data Source='" & myPath & " '; " & "Extended Properties=Excel 8.0;")<br />
objAdapter = New System.Data.OleDb.OleDbDataAdapter("select * from [sheet1$]", strConnection)<br />
objDataSet = New System.Data.DataSet<br />
objAdapter.Fill(objDataSet)<br />
DataGrid1.DataSource = objDataSet.Tables(0).DefaultView<br />
strConnection.Close()<br />
<br />
Catch ex As Exception<br />
<br />
Dim er As String<br />
<br />
strConnection.Close()<br />
<br />
End Try
thanks

Use the objDataSet.Tables(0).Select("ColumnName = "& YourTextBox.Text")
This will return DataRow Collection that you can manage the way you wish
