VS 2005 Retrieve XML Data By Node Name?
Mar 30, 2009
I have a function that I pass in xml results and though I could call by Child position but appears now that some nodes if blank do not show up.
How can I call by name?
Below my code fails on the data (at bottom), on the field 'DesiredSalary' which isn't in the returned result.
#Region " fnYahooSearchResults"
Function fnYahooSearchResults(ByVal sXML As String) As DataTable
Dim myDataTable As DataTable = New DataTable()
[Code].....

I can't work out how to add nodes to a treeview as a child of a particular identified node.
The treeview.nodes.add function has seven overloaded definitions each of which seem to add it as a child of the root node. I can't find a way to specify the parent.
I've found this article which gives an example
TreeView1.Nodes.Add , , "root", "Root Item"
TreeView1.Nodes.Add "root", tvwChild, "child1_root", "Child1 of Root"
TreeView1.Nodes.Add "root", tvwChild, "child2_root", "Child2 of Root"
TreeView1.Nodes.Add "child1_root", tvwChild, "child1_child1", "Child1 of
Child1"
I've seen several similar articles with the same format. However this doesn't work. I get compilation errors. It doesn't match any of the function definitions, and tvwChild is not recognised as a constant.

May I define an empty node in a XML file then do something?
Dim ReasonNodeList As Xml.XmlNodeList = SomeNode.SelectNodes("./REASON_CODE/REASON")
Dim CReasonNode As Xml.XmlNode = ReasonNodeList(ReasonNodeList.Count - 1)
But maybe this node doesn't exist, I am not sure is there any error occurring during the running.Except the error of length of NodeList.

I have a TreeView populated with some nodes, and some of those nodes have children. Is it possible that when the node, or child is selected that the entire node including the children be selected? I still want to deal only with the value of the root node, but for the UI I want the root + children to be selected.

I have an XML node which I am adding to a generic list of xml nodes:
ListXml.Add(myXmlNode)
Now whenever I change the node afterwards, all members of the list turn into copies of the node. Why would the list keep track of this and more importantly how am I supposed to 'detach' my work node from that list?

I want to select a node from my tree view, whatever I select is going to get a record from my database, I need a unique ID in each node so it will collect the correct document relating to the selected node.
How can I do this? the name of the node maybe used more than once? Each row in my database has an ID and Title, the title is the name I guess the ID being unique needs to be tied in somehow.

I have a question on the best way to store model data for my app. My app will basically be drawing a bunch of elements (lines) connected to a node at each end. Im trying to decide how im going to store my node data (as well as element data). The node data im trying to store will consist of the node XYZ coordinates and some other info about the node. The element data will consist of the node numbers at each end plus additional info about the element. There a number of ways i've been thinking i can do this. They are:
1) Store my node/element data as a Dictionary object, where the key represents the node/element, and the value would be an array of the information i want to store.
2) Create a "Node" structure and an "Element" structure to store the info i want. Im a bit worried here as my model could potentially have thousands of nodes and elements.
3) Create a "Node" datatable and an "Element" datatable, and store my info in those instead. I can see some advantages in this in regards to displaying information to the user in datagridview etc. But then again i can easily pull the required data from a method i mentioned above, and generate the datatable when required.
Not quite sure what the best approach is. Either way i do it, i will be serializing whatever object i use to save the data to disk.

I have three tables in SQL server which I would like to show and access on a form. Table 1 contains account data, address, contact details etc. Table two contains data attached to a Person, tel no , Mobile no, Email etc. Table three contains details on what awards the person holds, i.e. one person can hold several awards.
Therefore I have a one many relationship between the first two tables and a one many relationship between the second two tables. This is set up in SQL
The first two tables are shown on a form, table 1 via a set of text boxes, table 2 via a datagrid control.
I would like the functionality whereby I could select a row in the datagrid showing the persons name and find the Persons_ID number then use that as a filter to a second datagrid view so that only the selected persons awards show in the datagrid.

Basically, it refuses to find the node when the root node contains an attribute.

When I do xml.SelectNodes("DataSet") with the xmlns in the root tag, it finds no nodes. If I remove the xmlns attribute, it works fine.How can I make it work while leaving the attribute?
