Asp.net - See If The Value Of An Element Is In A List?
Nov 26, 2010
[Code]...
Now I find myself needing to do both Foo() and Bar() if value is "7" - is there a simple way to do this with an If condition?
[Code]...
I don't want to have to declare & initialize two lists if I can avoid it. Edit: I should have mentioned that this is a simplified example - there are actually a dozen or so CASE statements, and Foo() and Bar() are actually placeholders for quite a bit more code - it's seeing the same block of code repeated over and over that got me thinking about a better way to do it.

I am new to Vb.net so I will need some handholding. I have been searching everywhere but can't find what I need.I'm creating an app that has two forms.Each form has two comboboxes.The comboboxes are populated via a list and the list is populated by reading a text file for each combobox.The second form is called from the main form to modify the entries in the comboboxes. When I select the displaymember in the combobox a value corresponding to that entry is displayed in the text box.Now here is what I need.
I need to be able to append new values to the list so when focus is returned to the main form the new value is present. I'm using a combobox and a textbox on the second form as the import.The combobox is used to either select a present value to be able to modify the value in the textbox, or is used to add a new list element.

I am working with LINQ to XML in VB (although answers in C# are great, too). First off- my code works, so this is not critical. However, I can't help but think that what I'm doing with conditional logic should already be doable using the LINQ query itself. Here's what I've got:
'Get the Description elements in the ResultData section where the value is "Op Code"
Dim opCodes As List(Of XElement) = (From c In xdoc.Descendants("ResultData").Descendants("Description")
Where c.Value = "Op Code"[code].....
Please don't be too critical of my method of locating the sibling nodes- the XML files are produced by a third-party testing device and this is the only generic way to get the values I need. What I'm really looking for here is a better way to handle the If block.

unordered text file of 3 columns to assign into 2 arrays. I've been given a graphing component which expects a two dimensional array for a scatter graph for the set of values in the last column.
How would I parse through the list given an indexed array of 215 possible 'zone alarm locations' and if an alarm log list item, of which there can more than one for any given zone location, compare in the two dimensional array any previous value and replace it with the higher valued one? The following are my declarations for the 2 arrays. It isn't clear to me why the array for the scatter data was defined as (999,1) knowing there are only 215 possible x values (alarm zone locations)

I am working on a realtime application where the data is addded to a List(of T) all the time. MB per minute
Elements older than X minutes shall be removed from the beginning of the list to free memory.
As far as i can understand will there be an internal (slow) redim when i add each element after i have reach the number defined with the Capasity metod. (I set that quite big from the start, but the data speed is unpredictable so it can be exceed)
What happens each time i remove and element from the beginning of the list , seems like it takes a lot of time, ? new redim ?
What is the most CPU fficient way of removing 1 or many elements from the beginning of such a list?

I have a number of rewrite rules for a lot of things that I did in IIS7, like removing trailing slashes, canonnical URLs, lowercase lettering, and such. IIS altered my web.config, and everything works fine on the website, like it should. But in the Visual Studio web.config, the opening < rewrite > statement is underlined in blue, and at the bottom of VS, it says that the element 'system.webServer' has invalid child element 'rewrite'. But this is how IIS made it. I didn't do this manually. Should I be concerned with this VS error, or should I just leave as be, since it's working how it should work? Here's an example of my web.config:

I have been doing well and also I am a noob I know it and you know it a lot has started making sense and I am evening figuring new things out without using Google but of course I have hit another snag in my program so here goes
I am waiting for an email to arrive (the page automatically refreshes) and then I want to click the link (I do not need to click to open the email or anything like that) I also have the code to click and navigate to the address reason being it was the only way I could figure out how to stop it opening in a new window on IE
So my only problem is I need a way to check every x seconds for the element and then if its there proceed with my code and if its not wait and then check again or however this is done in VB.If this is not the way its done please point me in the right direction the code I am using to find and then navigate to the link is
Dim emailpageelements As HtmlElementCollection = WebBrowser2.Document.GetElementsByTagName("a")
For Each emailver As HtmlElement In emailpageelements
If InStr(emailver.InnerHtml, "https://twitter.com/account/confirm_email/") Then

I want to be able to reference an element in an array of structures by the name of the element in a visual basic 2010 function. For example
Public Structure myStruct
Public element1 as string
Public element2 as integer
Public element3 as boolean
[code]...
Is it possible to reference a structures element by the element's name in a similar way to that shown above. The code shown above does not work, as the expression obj(i).[elementName] does not work as hoped.

from the documentation we have this: Multicast Delegate: Represents a multicast delegate; that is, a delegate that can have more than one element in its invocation list.
so am i right to say that Multicast delegate is no different from a normal delegate other than the fact that it has arguments. so System.Action is a 'normal' delegate whereas System.Action(T)(Byval obj as T) is a multicast delegate?

So I have this code, which is supposed to add all those items in separate columns to ListView1 from WebBrowser in a "For Each" loop as you see - items with attribute "c4" go to one column, with "c5" to second etc.. Seems easy to do, but this crap is just driving me mad. What I get is ArgumentException error and message saying "You can't add or insert element "" in more than one place...". [code]
