Asp.net - Checking A Html Elements Class Attributes Value Contains "String"
Nov 10, 2010
I have two user controls that need to add a class atribute to the body tag of my page, however they currently over write one another if I just use Body.Attributes.Add("class","value") So I need to check if the class attribute exsists and if it already contains the value Im going to add.
If Not Body.Attributes("class").Contains("value") Then Body.Attributes.add("class", Body.Attributes("class") + " " + "value") End If
EDIT: The contain constraint doesnt return the expected value, resulting the the class not been concatinated, Example: add class "dog" then I a different instance of the same control tries to add "dog" but the contains("dog") returns false

I created a method and pass the element type, id, and any inner text that instantiates a new html element. The last statement: Me.Controls.Add(element) adds it to the end of the page, but I would like it to be inserted in a specific position (between 2 divs within a form). What I am describing is very similar to this post on SO here, although it was for javascript.

how find an object's type when it is a subclass of another object and I only know the string value of the object's type's name.
I created the follwing classes:
Public Class word
End Class
Public Class noun
[Code]...
Using 'TypeOf', I correctly see that pn is a properNoun, a noun and a word. The problem is, using 'GetType' to check pn against a string value, I can only see that pn is a properNoun, not that its parent classes are noun and word.
Is there a way to check pn against the string value "noun" or "word" and get back a positive result, indicating that pn is indeed a noun and a word as well as a properNoun?

I have a dataset which I am populating via an Oracle SQL query:
SELECT col_id, col_desc
FROM table_data;
Then I generate the dataset, via the function
Dim ds as New DataSet
OracleDataAdapter.Fill(ds)
Now, when I get the XML of the generated dataset via:
Dim strXML as String
strXML = ds.GetXML()
When I read/display the string, it is showing as follows:
<NewDataSet>
<Table>
<COL_ID>ABC001</COL_ID>[code]....
How would I be able to accomplish this? I would read the rows from the table in the dataset and construct the string?

I'm trying to create a treeview in a VB 2008 project that shows all the elements and attributes of an XML Schema.The MSDN documentation for XML schemas seems to imply that by loading the schema into an XMLSchemaSet and compiling it I should get access to all the elements and attributes with their values but this doesn't seem to work in practice.
Using a for loop such as:For Each elem As XmlSchemaElement In compiledSchema.Elements.Values
I can use elem.Name to get the element name (and attribute name with a similar nested loop) for a simple type but this doesn't work for a complex type.Whenever (and however) I try to get values for complex types I hit a brick wall.

I have given the local name of an element or attribute and the schema for the document. What is the easiest way to determine the basic datatype of the element or attribute. By basic datatype I mean the xs:string, xs:date etc. (The built in data types for the xml schema.) One of the problems I face is that it is rare for the elements type to be one of the basic built in types. 99% of the time it is a complex type that 50% of the time refers to another complex type that refers to another complex type and so on.
A simple Example for this schema: I want to find the basic type for Employee/Person/Name/LastName (determine that LastName is xs:normalizedString).
In the schema Employee is defined as an xs:element and type="bns:EmployeeType"
EmplyeeType has a Person element defined but it is type "PersonType" and then Name in person is NameType which is a complex type that extends GeneralName type that is type BasicNameType and that type finally defines the LastName which is of type "LastNameType" and on and on. There also definitions etc. I am currently writing a parser using linq-to-xml to get at this but it isn't easy or pretty. I have searched for other solutions and haven't found any but I fully admit my XML/schema/XPath ignorance. Is there an easy way to get the basic type for elements?

I have a problem of getting the string from the html class. When I debugged the project and I clicked the button, httprequest was connecting to the site then reading the pattern string from html class to get string, but it filled as a blank text.
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
'Create a request for the URL.
Dim request As WebRequest = WebRequest.Create("[URL]")
' If required by the server, set the credentials.
[Code] .....

I seem to occasionally find myself trying to compare two List(of T) to see whether or not they contain the same elements. A quick check of the documentation shows the SequenceEquals method, but that appears to check whether the two lists have the same length, and have the same elements in the same order. I don't care about the order. I want to know whether two collections have the same elements. Doing this is not terribly difficult, and seems common enough, so I was expecting that there would be some function that handles it.

I'm making a bot to auto-reply to my PMs on a website, and I'd like to get all of the HTML elements with a class name 'InboxRow'. I can get the HTML element one at time, but the problem is that these will be dynamic, so the id and amt. of them will always change, so I want to put them in an array, where I can call each one up and perform the rest of my code for it. I just can't seem to be able to figure out how to find all the HTML elements with the class name and put them in an array, and I can't seem to find any tutorials online

I developed a WebBrowser which loads a certain web-site for me. The next task, I would like to see only a certain info on that web-site which acts like a table serving as special informational news for me. So, I don't want another things to be appear on my loaded web-site. I need to hide html elements, so that don't appear on my loaded web-site. So, then the form will be like smaller and it will be more convenient to use. Maybe, I need also to hide or remove some java scripts. Do you have any recommendations for it?

I have the following code in my application which gets the attributes "name" and "id" of all the html elements on a web page.
[Code]....
What I would like to do is place the returned results into a 2 column listview control with the name attribute in the first column and the id attribute in the second column. After searching the internet the only good example I could find is on the msdn pages but this only shows how to add a known set of items so I could not figure out how to convert this to work with variables.

I'm just curious why class/property attributes in VB.NET have a weird optional syntax such as:
<TestAttr("a", "abc", Optional1:="foo", Optional2:=3)>
VB.NET allows you to set optional parameters like this to avoid order restrictions (which is lovely) but in this case it's forcing you to that.For example this is not possible:
<TestAttr("a", "abc", "foo", 3)>
even though the parameters are in the same order as the original definition.
