I'm trying to get the price out (90.0) of this xml document but get it to work, i've tried using the xmlTextReader and the ReadElementString function but I guess I need to get the attribute. I then looked at using the GetAttribute function.

I am trying to read all the attributes, there are 3, from a single node. This is what I tried from an example I found:
Code:
Dim xl As New XmlDocument
xl.Load(XMLfile)
Dim rn As XmlNode = xl.SelectSingleNode("p1")
[code]....
I have used a messagebox to show the xl.OuterXml, I see the file is loaded.
The following function copies a file from Source & Path to Dest & Path, normally setting file attributes to normal before copying.Yet, a user of my app has reported it to fail when copying readonly files, returning a permissions-related error. The user is however running the code as administrator, and the error happens - quite strangely - on the SetLastWriteTimeUtc line.Although the code reports that the file attributes are set to normal, windows explorer shows that they are set to read only.

I am currently trying to read an XML file and display the information within a Datagridview. I currently have this working using the below
Dim xmldoc As XmlDocument
Dim xml_nodelist As XmlNodeList
Dim xml_node As XmlNode
xmldoc = New XmlDocument()
xmldoc.Load(openFD.FileName)
[Code] .....
Basically what I want to be able to do is for each <ADVERT> node, so in this case there would be two, I can get the information from both the TITLE and NAME attributes and add them into the Data table which then gets displayed within the data grid view. Currently I can only get the TITLE attribute values to show?

I'm trying to pass a business object from one WinForm to another WinForm for modification, and then repopulate the text boxes, etc. on the first form with the updated values.However, it seems that the object values set in the second form are not "sticking" when the code control returns to the first form.Is there a way to view the memory location of an object in VB.NET? I want to first make sure that the object variable on the second form is pointing to the same memory address as the object on the first form. Then I can take it from there.
In a separate VB project, I passed a simple object to a second form, modified the values, and re-displayed the object's values on the first form. It worked fine. In my real app, I'm passing an object that is a property of another object, which may be why it isn't working.SOLUTION: The problem was that I was using a DeepCopy() function that I found to simplify copying the properties of one object to another. Removing that function and manually setting the values to the passed object on the second form (ex. obj.property1

I am creating some reports using object datasources.in my software the user can create a list of products specifying a code, the product name, the price and the vat rate (this last two attributes will be used as suggestions when the user will place the product inside an order).When a user creates an order he can place products within it by specifying for each product the quantity and he can also override the suggested price and the vat rate.So basically i have two models to represent the products:
ProductModel (used to define product name, product code and the default suggestion for price and vat rate)OrderProductModel (used to place products within an order, specify the quantity and override the default product suggestion for price and vat number)
ProductModel:
id
code
name
[code]...
(suppose orderProduct is an instance of OrderProductModel)Now the question is "how to define the report rule to access to code and name?"...I am using visual studio 2010 and by reading here:[URL]they says that the syntax: =Fields!Object.Value.attribute no longer works...
Is this class normally slow or maybe there is something in my process making it slow.I have to import 170,000 rows of data from a fixed length text file into a SQL table. It takes about 2 minutes in a DTS package on SQL server 2000. But we are migrating to a SQL 2008 server and since this code has several manual steps and does not manipulate the data I thought it would be easier to use the TextFieldParser object to handle reading in the data.
Here is the code:

View 1 RepliesAfter browsing the internet on how to read RDF Triples, the only things i came up with were user created libraries and so on. Some MSDN documentation on Microsoft's website confused me as well, as trying to import the Namespace shown was not possible. (Maybe it's possible just in C#? no idea).So how would someone read an RDF Triple using VB.NET? RDF is an XML format in which data is stored in triples: subject, predicate, object.
Example:

I am somewhat new to object oriented programming and am attempting to flatten a Linq object hierarchy by using a shim class.how to initalize a derived class with property values from a base class?I have two objects, a base object with about 100 properties, and a derived object which inherits from the base object and adds a few additional properties beyond those of the base object. My simple constructor creates the derived object, but I am looking for a way to initialize the derived object properties with values from the base object.Right now I am using reflection to iterate over the properties individually and I suspect there may be a better way. The following example shows my shim class constructor for the derived class, and two properties:
newProperty1 - a new string property of the derived class
flattenedProperty2 - a new string property of the derived class, copied from a 2nd-level object of the base class
Code example:
Public Class derivedObj
Inherits baseObj
Private _newProperty1 As String[code].......
Is this the correct constructor approach to flatten the object hierarchy using a shim class? My second question relates to initialization of properties in the derived class. The constructor above creates the derived object, but what is the best way to initialize the derived object properties with values from the base object? The following code uses reflection to iterate over the properties individually, but I suspect there may be a better way.
Code example:
' property names are in the string array fieldNames
'baseObjQuery is an ienumerable of baseObj
'derivedObjList is a list of derivedObj[code].....
Is there a simple way to initialize values for the properties in the derived object based upon the values of the common properties in the base object?

View 1 RepliesI'm writing a class-library in VB.Net and one of the subs that are being called from the application which is using my library has more or less the following syntax:
Public Sub LoadDict(ByVal PhoneticType As String, ByVal strDict As String)
where PhoneticType can be phonSoundex, phonDoubleMetaphone or noPhonetic
I want to give the application-developer a possibility to select the PhoneticType from a list when writing the call of above sub (I think it's called attribute-arguments). This would make it easier for the developer since spelling-errors can be avoided and which will avoid errors when using the library. I think it's all about attributes but I haven't managed to get it to work despite trying.

For example, after graduation and summer school, we delete the folders that belong to the (now) prior students.

We do this practice to manage our disk space.
