If a node belongs to a namespace, it's children by default belong to the same namespace. So there's no need to provide an xmlns attribute on each child, which is good. However. If I create two nodes like this:

I need to read an xml document from a database record into an XDocument object in order for it to be deserialized. So that the deserialization will work, I need to apply a specific namespace to each of the level 1 elements. So XML looks a bit like this:

How do I prevent the blank/empty namespace being added to each child element of the element to which the required namespace has been applied?

View 3 RepliesI'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 problem with my treeview. I have two child nodes with different parents which contains a literal (*x). In this case (*1) (view image)
[Code]...
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 an xml similar to this one[cod]e...
View 5 RepliesI'm using VB 2008 and I'm trying to add a xmlns="mynamespace" attribute to an XDocument's root element.The XML document is created by a 3rd party, and I have loaded it into a VB XDocument object. As it comes, it has no namespaces. I have been working on a local copy and I added in a namespace in a text editor, so that I can use the XMLToSchema in VB to enable intellisense etc, as per the instructions in the Beth Massi vids at MSDN. Now the rest of the code works I want to open the live documents again. Without the namespace, my XML literals don't resolve.I've tried unsuccessfully to add in the XMLNS property to the root tag using a few methods, and the nearest I got was the following three code samples.
Dim myNS As XNamespace = "urn:nbf:namespacename"
myXML.Element("nameofrootelement").Add(myNS)
^^^^ The namespace was added as the value of the root element, not as an attribute.
XML.Root.Add(New XAttribute("xmlns", "name"))
^^^^ Generated the error: Run-time exception thrown : System.Xml.XmlException - The prefix '' cannot be redefined from '' to 'name' within the same start element tag.
but
XML.Root.Add(New XAttribute("test", "name"))
^^^^ works correctly. Presumably it doesn't like me manually trying to set a reserved attribute? This namespacing seems way too over complex from some of the Googling I've done.I thought to .ToString it, then modify, then .Parse it also, but I wanted a better solution so that it would help me understand it a little better! I did try this though, and as you rightly point out, it affects all the descendants too, so thus it still breaks.
I will be working with multiple XML feeds all produced by different third parties, and I think for simplicity I will be leaving out the namespacing entirely!My own custom parsing function rewrites the third party feeds into one uniformed document, which then gets processed by another routine. I'll be able to add a ns to that intermediate piece of XML which will help when coding the secondary function.
I'm experimenting with xml literals in vb.net and there's something I don't get. Here's a small sample that illustrates the problem. I'm adding two PropertyGroup nodes to an empty Visual Studio project. The first one is added as xml literal, the second as new XElement:
Imports <xmlns="[URL]">
Module MyModule
Sub Main()
Dim vbproj = <?xml version="1.0" encoding="utf-8"?>
<Project ToolsVersion="4.0" DefaultTargets="Build" xmlns="[URL]">
[Code] .....
This code writes the following output:
<Project ToolsVersion="4.0" DefaultTargets="Build" xmlns="[URL]">
<PropertyGroup xmlns="[URL]"></PropertyGroup>
<PropertyGroup />
</Project>
As you can see, the first PropertyGroup node contains a redundant xmlns declaration. Why is that, and can it be avoided?
i want to select specific nodes of a xml document.Everything is ok until the document has an xml namespace. Then when i try to select the specific nodes no node is being returned.. This is because an xml namespace is declared. Is there a way to select those nodes and ignore the xml namespace ?

<?xml version="1.0" encoding="utf-8"?>

I am building a tool that takes an XML document and replaces XML nodes with a different XML node using .ReplaceChild. This all works great. The nodes get changed to the proper nodes. Where I seem to be having an issue is that the new node is inserted with an xmlns="" attribute, which I am not specifying for it to do, nor do I want as an attribute. How can I stop the ReplaceChild from inserting this as an attribute, or am I going to have to remove the attribute after the node is replaced?
Dim imgSrcNode As XmlElement = xmlDoc.CreateElement("img")
Dim imgSrcAttr As XmlAttribute = xmlDoc.CreateAttribute("src")
imgSrcAttr.InnerText = "./art/" + imageName.Substring(0, imageName.LastIndexOf("."))
imgSrcNode.Attributes.Append(imgSrcAttr)
mmlNode.ParentNode.ReplaceChild(imgSrcNode, mmlNode)
Resulting XML change:
<img src="./art/equJI161298_1" xmlns="" />
XML change desired:
<img src="./art/equJI161298_1" />
How to check child nodes tag.

Is it possible to have more than one level of child nodes in a treeview? fore example can i have:

right now it only lets me have
node1

I have the following code which checks for the value of the 'cc_supplier_status' column for each of the rows in my table. If the state is 0, I need a child node to be added to a node named 'Inactive Suppliers' in my tree view (tvw_Supplier) with it's text being the value of the 'cc_ supplier_ name' value for the same row.If the state is 1, a child node is to be added to a node named 'Active Suppliers'.If the state is 2, a child node is to be added to a node named 'Pending Suppliers'.The code I have now just filters out the status value for each row, and performs a select case on it. I need to know how I'd add a new child node to the parent nodes mentioned above.[code]

I have a bunch of XML's that need to be put into an SQL database. One XML represents all orders for a certain department of a store. The problem (for me) is that in one XML there can be (and are) multiple orders (called distributions in my case.) The XML looks as follows (truncated):
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<order><process_id>322867</process_id>
<key1>RET</key1>
<key2>40_134985</key2>
[code]....
So in this example I have two 'distributions'. Now I can get all data out of the XML fine, which I do like this:
get xml data
awsFeed = XDocument.Load(fileName)
Dim orders = From order In awsFeed...<order> _
[code]....
However, in this case my SQL input would have to result in 2 entries, because there are 2 orders. Both entries would have the same data, except for different entries. I know how to post to SQL, that's not the problem. My real problem is, how do I 'loop' it through the XML. I think i'm looking for something like:For each 'distribution' in orders -> put into array.Or something like that. After that I could query the array and put it in the database.

adapted from Major treeview/list view head ache I managed to make the treeview display the folder and the sub folders... but it isn't very hierarchial. Check attached pictures. Image1 shows how it is and image2 shows how I want it to be. Can anyone tell me how to get it to look like image 2?...Image2 was made in Windows Explorer. Image1 is a screenshot of the runing program that I am trying to make. I have been googling around but no luck so far. Practically I think what I shoul be asking is how to create child nodes of subfolders. The program is going to copy whatever the user checks in the treeview into another folder chosen by the user. I am using Visual Basic 2008 Express.
I have an XML file and I have a function to which this XML is passed as string. I have loaded this string in Xmldocument and I need to insert few children nodes under one node. This function returns the modified XML string. I want that whenever this function is called, new child nodes are added, currently, It adds child nodes once.Do I need to overwrite the XML file ? If so, How can I replace the node with new node ( with new child nodes added) so that It has child nodes added before the function is called again ?

What I want is when a user clicks on Apptrackr it runs this piece of code
WebBrowser1.Visible = true
DownloadsBrowser.Visible = false
