So you're looking to control the order of the children that show up under a node in the tree?? You can't control that. XML doesn't make any distictions about the order of child nodes common to one parent. Only that parent nodes must come before children.
You'd have to load all the current children into a collection, remove them from the XML document, then add them back to the parent node in the order you want them to appear.

I'm not sure if this is exactly what you are looking for, but I use an object of type System.Xml.XmlNodeList to reference xml nodes (I use VS2005, not sure if it's in other versions). The GetElementsByTagName will return a NodeList with all of the nodes that match the name. For example, this bit of code will set the variable strValue to the value of the first element in the file named "Element1":
Dim xDoc As New System.Xml.XmlDocument<br />
xDoc.Load("C:\MyFile.xml")<br />
<br />
Dim strValue as String = String.Empty<br />
<br />
Dim xList As System.Xml.XmlNodeList<br />
xList = xDoc.GetElementsByTagName("Element1")<br />
<br />
If xList.Count > 0 Then<br />
strValue = xList.Item(0).InnerText<br />
End If
Hope this at least helps point you in the right direction.

You could try to add a key attribute to the nodes that have to be sorted. Then write a class that implements IList and keeps its elements sorted after adding. That way you cannot sort the nodes in the xml file but have them sorted in your program. On the other hand, if you add another function that returns a sorted XmlNodeList you can insert the result of that in your XmlDocument and have a sorted list of childnodes in your file.

Hi Folks
I have this basic code.
Dim db As New MyLinqDataContext
Dim o As New Order
o.OrderName = "Cool Order"
db.Orders.InsertOnSubmit(o)
db.SubmitChanges()
db.Connection.Close()
(I originally have tried this on C#)
I have an orderid column which serves as a primary key which should update automatically when i insert the record.
When the code runs there is no record but the database is not updated. Anyone else having issues with this. Im using the express versions of visual studio 2008. thx in advance.

I am not very sure about this....
Is ur Database have auto commit option??? If not commit the transaction first
Good Luck

Hi all,
I want to save a webpage that contains tables into an excel file

What's the question?? What part of this are you having problems with??
You can't save the table directly to Excel. You have to parse it out of the HTML data and put it into the cells you want, one cell at a time.

Hello every one
I have a Vb 2005 Express application.
I am using a label over a picture box (it has a scroll bar).
I want to have the background color of the label as transparent so that whenever the picture box is scrolled in the background of the label, every thing can be seen
But when I do this the back color of the label is of the color it first gets..
What should be done??
|
|
|

A Transparent background is NOT transparent. You cannot see the other controls on a form through a transparent background. Transparent means that the label control will use the background color or image properties of the parent form. If the background of the parent form is yellow, you're label's background will be yellow.
You'll have to create your own version of the label control, providing the painting code to create the effect you want. You can find an example of such here[^], or here[^], or the entire list of Yahoo search results for ".net transparent label control[^]".

That's because, starting with .NET 2.0, the security tools have been moved to the .NET Framework SDK. They don't ship with the redistributable version.
Read here...[^]
|
|
|
|
|
so how do we configure framework 2.0 security except using caspol ?
thanks in advance
hello
|
|
|
|

You didn't actually read the link I posted, did you? Perhaps followed the links on that page to the place where you can probably download the SDK version and grab the security tools from it, maybe...

Hi all,
I have created a COM wrapper component in c#.net. I generated .tlb file out of it. Also I added reference to tlb file in VB 6.0 application and can able to call functions of COM wrapper.
In C#, i have declared a stringcollection to collect all the errors.But while mapping,this String collection is converted to Unknown in VB 6.0 and becoz of that i got mismatch error.
so i changed the stringcollection to Arraylist in C#.
This Arraylist is converted to String in VB 6.0 while mapping.
and i got error while i tried to retrive the string.
Plz give me suggestions on how to call a Stringcollection/arraylist in VB 6.0.
Thanks in Advance,
cheers

You cannot pass any System.Collection objects back to VB6. You'll have to convert this collection to an array of strings to send it back to VB6.

What are the differences?

I need to crete child Nodes
|

I am guessing that you have more than one episode per patient and more than one visit per episode. You can always write your own filter to create the XmlDocument you need by iterating through the rows and adding the appropriate nodes to the XmlDocument. Then you can call the Write() method of the XmlDocument.

Yes you are right... but i dont know how to write node by node using Dataset.. pelase can u help me
|
|
|
|

Try something like this:
Dim doc As XmlDocument = New XmlDocument()
Dim tableName As String = "myTable"
Dim node, attrib As XmlNode
Dim parentNode As XmlNode = doc.DocumentElement
For Each row As DataRow In ds.Tables(tableName).rows
node = doc.CreateNode(XmlNodeType.Element, "myElement", myNameSpaceURI)
attrib = doc.CreateAttribute("myAttribute")
attrib.Value = row("myAttributeColumn").ToString()
node.Attributes.Append(attrib)
parentNode.AppendChild(node)
Next
You just need to adjust this to fit your own table.

Why don't you use Gridview with checkedboxes?
lembayung wrote: do i have to create another table?
Yeah.. there will be three tables like Students, StudentCourse, Courses.

im new in vb so i dont much....regarding to ur reply, are you referring to vb.net?do we have gridview in visual basic?
|
|
|
|

Wow.
If you're that new to VB, you should be buying a book on winforms and reading it. Yes, VB.NET has a gridview control.
