Dec 25, 2009I need to take six altitudes altitude1 and altitude2 and check to see if they are with in a value of 250 of each other. Then if there are any that are within 250 of each other, to make them turn red.
Second thing is:
I need to take 6 altitudes, and arrange them. I have them in panels and I have 6 empty panels as place holders for .location value however I need to know how to look at 6 values and say arrange these values accordingly highest number this place lowest number this place etc.
I have looked everywhere on the internet and maybe im just retarded when it comes to math in vb.net.

View 4 RepliesStringCollection Or ArrayList Within Class?
Nov 10, 2009I have a class called CookieMonster, its objective is to simply create a cookie based on 3 parameters passed to it. The cookie name, the cookie name-value pairs and the cookie expiry date.I have experimented with List(of T) and Array and StringCollection, but I'm unsure which is the best for passing the name-value pairs and providing that information to the class.Ideally, I'd like to be able to do something like this:

.net - Convert StringCollection To List<String>
May 10, 2009Normally, I'd choose List<String> [or, in VB, List(Of String)] over StringCollection whenever possible: see also Best string container.
However, as it seems, generics — and hence, List<String> — are apparently not supported in VS 2008's settings designer. Therefore, if I want to use a list of strings in my user settings, I have to resort to using a StringCollection there.
Now as I don't want to see StringCollection throughout my code, I need to convert it to List<String>. How do I do this efficiently? Or, even better, am I mistaken and there is a way to use List<String> in settings designer?

Create A StringCollection Setting And Manually Enter Some Data?
Jan 16, 2008I have used My.Settings for quite some time now, in both VS2005 and now in 2008, but never noticed this behaviour yet... I must be forgetting something trivial? I create a StringCollection setting and manually enter some data (strings).I write some code to handle this, and I get it to work.
Then, I manually add some new strings (and edit the older ones) in the Settings page, save the project, and run my code again.For some reason, the last changes have not been saved... Whenever I look in the settings page, I see them there, but my code cannot recognize them..

Find A Substring In An ArrayList, StringCollection Or List(Of String)
Jun 7, 2010I've got some code that creates a list of AD groups that the user is a member of, with the intention of saying 'if user is a member of GroupX then allow admin access, if not allow basic access'.
I was using a StringCollection to store this list of Groups, and intended to use the Contains method to test for membership of my admin group, but the problem is that this method only compares the full string - but my AD groups values are formatted as cn=GroupX, etc....
I want to be easily able to determine if a particular substring (i.e. 'GroupX') appears in the list of groups. I could always iterate through the groups check each for a substring representing my AD group name, but I'm more interested in finding out if there is a 'better' way.
Clearly there are a number of repositories for the list of Groups, and it appears that Generics (List(Of String)) are more commonly preferred (which I may well implement anyway) but there is no in-built means of checking for a substring using this method either.
I've settled on using a List(Of), and I've borrowed from Dan's code to iterate through the list.

String.ToCharArray() Stored In StringCollection Conversion To Numbers And Back
Aug 25, 2009I have a string which was converted to a char array and stored in a stringcollection, how do I return the numerical value for the character in each string? How can I reverse this process, getting the character from the numerical value?
I know I could code a Select Case statement, but that would take a very long time as I need to cover every character a person could want to conceivably use in the English language, including punctuation. Is there already a method built into vb.net for doing this?

View 39 RepliesPrepend A String To All Strings In A List Of Strings?
Aug 5, 2010I have a list of strings. For each string in that list, I want to prepend another string. I wrote a method to do it, but I was wondering if there was something already in .NET I could use to do this. It seems like something that could be built in, but I was not able to find anything.
Here is the method I wrote:
Private Function PrependToAllInList(ByRef inputList As List(Of String), ByRef prependString As String) As List(Of String)
Dim returnList As List(Of String) = New List(Of String)
For Each inputString As String In inputList
returnList.Add(String.Format("{0}{1}", prependString, inputString))

It works, but I would rather use built in functions whenever possible.
VS 2008 Using List Of Strings Or Array Of Strings?
Oct 16, 2009I'm migrating from VB6 to VB.NET, in hence my questions below:
I have to write a function that returns array of strings.
How can I initiate it to empty array? I need it since I have to check if it's empty array after it returns from this function.
Is list of arrays better for this purpose? If I use a list - Is it empty when it firstly defined? How can I check it it's empty?
Find Strings Inside Strings?
Aug 15, 2011I have been looking for examples to find the string between two strings. This top one works fine;
Public Sub ReadData(ByRef keywordStart As String, ByRef keywordEnd As String, ByVal filename As String)
Using reader = New StreamReader(filename)
[Code].....
Now the first one is fine - Ext_Volume is result of the string between the strings <Volume> and </Volume>. <Volume> and </Volume> are unique so this is straight forward.
However the second one - "^FDExp:" is unique, but "^FS" is not unique. There are occurances of "^FS" before and after "^FDExp:".
How do I get the string to search AFTER the occurrence, not before etc?

View 2 RepliesDataGridView - Convert Nulls To Empty Strings And Display It In The Grid As Empty Strings
May 14, 2009I have a DataGridView that has some columns with dates. It binds to an in-memory Datatable which gets loaded from an string array of data passed back from the backend Some of the rows returned have nulls for the date columns. Solution 1: If I define the Date column in the DataTable as "string" I can easily convert those nulls to empty strings and display it in the grid as empty strings (desired results). However, if the user clicks on the date column header to sort by date, it doesn't order the rows as you want. You get a purely string sort order. Not acceptable

System.Collections.Specialized.StringCollection Vs System.Collections.Generic.List(Of?
Feb 5, 2011[code]...
What's really the point in using the former?It's hard to use linq if I used the former. I have to convert that to an array first which is difficult because there is no (asarray) function.I think I would change all of my code that's using System.
