Extracting From A Collection?
Nov 21, 2011
I have two collections that I am comparing to a thrid collection. Both collections have 147 values in them. I am wondering how I get the results of the comparisons in a text document concatinated to look like this:
Output from Collection A Comparison
Collection B results
Repeat the above two line until all results have been written to the text file. Currently the program runs and the document is not created. Here is the code:
Dim sb As New System.Text.StringBuilder
Dim ordersCount As Integer = &H3E8
Dim i As Integer

Is it good practice to store sub-collections of item X inside a parent collection of item X for caching 'filter-queries' which are performed on the parent collection? (They won't be used together (as in color AND type).) Or is it also ok to just Loop over the collection and return the correct entities in a temporary collection?

I've got the following ADO.NET Entity Framework Entity Data Model:I want to find all the Policyholders with both a Service of a given Id and also a Keyword of a given Status.
This LINQ Does Not Work:
Dim ServicesId As Integer = ...
Dim KeywordStatus As Integer = ...
Dim FoundPolicyholders = From p As Policyholder In db.PolicyholderSet.Include("Keywords").Include("Services") _
Where p.Services.Id = ServicesId _
And p.Keywords.Status = KeywordStatus _
Select p
The Where clause cannot search the p.Services and p.Keywords EntityCollections in that way.

I've been working with a CMS called InsiteCreations 2008. I'm running into an error I just can't wrap my head around. I would even be willing to compensate anyone a small amount over paypal, for a solution. The error is rare in occurance, and appears when clicking about 3-4% of links to other pages within our CMS.The full code page is quite large, but there seems to be only one function associated with the error. The error also only appears when not logged into the CMS. If logged into the CMS, clicking the link simply displays the page as normal. I have already checked permissions on the page from the CMS admin console, and it is public.
The error message is as follows:
Server Error in '/' Application.Collection index must be in the range 1 to the size of the collection.
Description:
An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Take the following scenario:
Public Class Store
Public Overridable Property Areas As List(Of Area)
End Class
Public Class Area

What's the quickest way to get a total count of shelves for a store? I.e. for a store I get the total count of areas by using Areas.Count Or will I need to loop through each area and tally the count of shelves?

I have an ASP.NET app with lots of textboxes all over the page that need updating at various points through program execution. These textboxes actually belong to a certain class, so for easy updating I thought I could create a Dictionary(Of string, object) and add the control.ID and the control to it and then for updating do something like this:

I need to convert a VB Collection to a modern one, like Dictionary or Hashtable. For my approach, I need the Collection's KEYS. Googling tells me that it's impossible. Re-writing the entire application using new collections is not an option as the application is really old and large (converted from VB6 to VB.Net).Using the old Collection also is not good - as there are new components in development.Converting a - for example - Hashtable to Collection works:
using VBCollection = Microsoft.VisualBasic.Collection;
public static VBCollection ToVBCollection(this Hashtable table)

I've been having problems extracting the value of a Regex in a String. I have a string with several regex expressions and I need to get the value of each expression's match. The thing is though, it's not returning the last match correctly. For example:
Regex Pattern: I play (S+.*?) and (S+.*?)
String: I play the guitar and the bass The program is returning the value of the first expression as "the guitar" but it's returning the value of the second expression as "the" instead of "the bass".

I want to retrieve a collection of strings that are enclosed in Args("") in the expression.

Does anyone know of a way that you can get the string that is held at this reference point (its the contents of a registry value that corresponds to a string - see this thread for more info [URL]
@%Systemroot%system32wbemwmisvc.dll,-204
I think I've seen C# (or maybe C++) code use lines like this but I cant find any way of getting the value from the DLL in VB.NET

I am trying to test bit 7 (87654321) in the byte DB2 to check if its true. The below code does not seem to be working:
If DB2 And &H40 = &H40 Then Label1.Visible = True
If DB2 And &H40 = &H0 Then Label1.Visible = False
TextBox6.Text = Hex(DB2 and &h40)
I do see the value of DB2 changing from &h00 to &h40 in the textbox, but when evaluating in the two if statements, it never evaluates to true (for testing, the only possible values for DB2 right now are &h00 and &h40)

I realize this may be a simple request, but I am fairly new to VB so even the simplest tasks are sometimes over my head. Basically, what I need is a function that will take a URL from one of the text boxes on my form, and extract a certain piece of text from that URL. The problem, for me, lies in the fact that the text in question isn't always in the same position, character wise, every time. Basically, the URL looks something like this:
url...randomNumbers rarely seems to be the same amount of characters each time, however the randomNumbersINeed always appear after the second underscore and end right before the third underscore, no matter the amount of randonNumbers that appears before hand.The process I am working on does the following:
1. Takes the raw URL that I have pasted into a text box on the form.
2. Declares that text as a string.
3. Extracts randomNumbersINeed from that string
4. Assigns or declares randomNumbersINeed as a string
5. Appends that string to a .txt file.
I can do steps 1, 2, 4, and 5 with no problem, in fact I've already got those set up in my code ready to go. I just need a function that could extract the numbers from the URL.Could someone help me out here or point me in the right direction?

If I have say a wav file as a resource in a form, is there a way that I can extract it when the program is run and set it as say... the windows logon sound? Or perhaps an image and set it as the wallpaper? Or does it have to be an external file that the form would have to handle?
