Is there a way to obtain a collection of ProcessThreads by ID like you can with processes? I know the ID of the threads and I need to obtain additional information about those threads. So I was hoping I could get a collection of threads and then pull the required info.
View 3 RepliesIs 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.

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'm trying to obtain data from a dll, but I do not know how to do it.My code is:
'Function
Public Declare Function SET_XML_PATH Lib "EbmPapstFan.dll" (ByRef ruta As String) As Long
Public Declare Function GET_PRODUCTS Lib "EbmPapstFan.dll" (ByRef ruta As String) As Long
[code]....
This isn't a mistake with the path because Int_A is 0. In addition, GET_PRODUCTS gives me the number of products that software has.The manual say that this function also has string character output.I don't know how obtain this other string character output.

my problem is that is have to create a program in which I enter some text in a text box and then in an other text box it will display the value store in a selected byte. I really don't know where to start. I have a form with three text box and a button. One of the text box to copy o write whatever I want, the other text box to write the number the byte I want to get the value and the last text box to display the value stored in the byte I choose. With the button I will start the function that will get me the value in the byte.

View 3 RepliesI have a general idea of what the code should look like but I can't seem to finish/put it together.I have a year's worth of data such as December 01, 2010 to December 01, 2011.The problem is that there are more than 365 points, some days for example have 3 data points and others have 4, etc..What I would like is to only have 365 points of data by averaging the data points for the days that have multiple points.
[Code]...
- So far I have another column with dates from Dec 1st 2010 to Dec 1st 2011.
- I think I'll need an IF statement for if the whole range of A column equals one of 365 days, it'll equal the average data.
- then I'll need to have a statement for x+1 date for each consequtive day.

Say I have a rolling collection of values where I specify the size of the collection and any time a new value is added, any old values beyond this specified size are dropped off.Obviously (and I've tested this) the best type of collection to use for this behavior is a Queue:
myQueue.Enqueue(newValue)
If myQueue.Count > specifiedSize Then myQueue.Dequeue()

I'm testing a window application which was written in VB.Net 2003.I set a few BreakPoints and Debug the project.When the debugger hit one of the breakpoints, it stops at there. Its correct.But when I try to add one of the variables to "Watch", it said "error: cannot obtain value".I tried to search the Net and found that some said "its because of structures", some said "its because of passing too many parameters." and some said "its because of too many line of codes (LOCs)".but my problem is not in passing parameters or too many line of code.the function i set breakpoint has only around 300 LOCs (including around 100 line of comments)And the value I tried to get is from my TreeView which is on my Win Forms.its very strange that I can't even get the value from Forms.
