Rename A Collection At Runtime?
Jan 10, 2012
Building a MP3 player fairly large but will upload the zip file if needed. It almost compelted. I am stuck on one thing I want to be able to create a playlist collection based on the name the user enters into a textbox and name the collection with that name if the user enters mysongs as the name the collection would be named mysongs. I know how do declare a new collection but there is no way to change the name to mysongs I am not limited to collections it could be an array or a list of strings my thought here is to save the list of mysongs to a collection to find the list if it already exists and open the list if found to a listbox I know how to go through the list and put results in a listbox. Maybe a collection of collections is not the right way to handle this?

I'm using VS2008, writing an app in VB.Net (3.5 framework), and I have a custom control which recieves a collection (each item in the collection has an image, and 2 text fields).When populating this at design time, it's nice and easy to do either in code, or even better through the very useful "Collection Editor" (in terms of user friendliness, at least).What I'd like to do is give my end users a similar Collection Editor interface, on my main form, to be able to add to and remove from this collection in a similar way to how it's done in the IDE. This is new territory for me, and I really don't know how to achieve this

I am trying to add controls to a collection runtime(toolstripmenus to a menustrip) However, when I try to loop through the collection, it says something like: "Collection has been edited. Listing function cannot be done" (it's a free translation since i have a finnish VB)

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
[code]....
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 am currently working on a project that contains a few images, that are placed in a lot of different controls. I was wondering, is it possible to rename those few resources images , ex. image1 name is bg, and when i click a button to rename that image to bg2 and rename bg2 to bg.. something similar to an image swap, just done by renaming resources. I will wait for a few suggestion, but if all lead to the same possibility, which I hope is not "no, you can not", than my time is narrowed down for better use, other than changing each control's image manually..

i want to rename a string that contains a number, when the program starts the string looks like this:
d1_filename, but could as well be like: d8_filename.
so, depending on the starting name, i want to rename the string.
If the string is d1_filename, the renamed string would be d2_filename.
or also: if the string is d23_filename, the renamed will be d24_filename an so on.

I have a VB 2008 project XYZ. It is in an XYZ folder. I want to keep it, but I also want a copy of it which I will call ABC which will be in the ABC folder. How do I do this? Just moving files to a new folder does not work. I have found a few places to make changes like the assembly name, but there seem to be many places and I haven't found them all. I found some old posts for earlier versions of VB but they are not applicable.
