I am so sorry for asking such a thick question. I need to sort the characters in a string using vb.net.
I normally use C#.
This is my code:
Dim val1() As Char = txtInput.Text.Trim.ToArray
val1 = val1.OrderBy(c >= c).ToArray()
Tells me that 'c' is not declared.
I have imported these:
Imports System.Collections.Generic
Imports System.Linq
Please tell me what I am doing wrong?
Thanks,
You're still using c# syntax for your lambda expression. See http://msdn.microsoft.com/en-us/library/bb531253.aspx for details of Lambda expressions in vb.
In your case its as simple as
val1 = val1.OrderBy(Function (c) c ).ToArray

This works for me: public static bool IsContainedWithin(this string @this, string container) { var lookup = container.ToLookup(c => c); return @this.ToLookup(c => c).All(c => lookup[c.Key].Count() >= c.Count()); } I tested it like this: var tests = new [] { "met".IsContainedWithin("meet"), "meet".IsContainedWithin("met"), "git".IsContainedWithin("light"), "pall".IsContainedWithin("lamp"), }; I got these results: True False...

The reason is that you are referring to the default instance in your second code snippet. Default instances are thread-specific so that second code snippet will create a new instance of the Form1 type rather then use the existing instance. Your Class1 needs a reference to the original instance of...

Given your example data where the first number is always a single digit: allScenes.OrderBy(x => x.SceneNumber).ToList() If you can possibly have multi-digit numbers, please provide them and where you want them in the sort order. This is one way to sort multiple digit numbers: var allScenes = new[]{ new {SceneNumber="4B"},...
The problem you have is that your model is not identical to you database, if you could select the row directly (you said Linq2SQL and not Linq2Entities) then you could update it again, which you do. If you select an anonymous type then you lose the context connection and cannot...

If you want to get results that reliably look like the BorderStyles on the machine you should make use of the methods of the ControlPaint object.

The non-generic IQueryable interface doesn't have extension methods of Count and ToList(). Only the generic IQueryable<T> does. If you can modify the library to return a suitable IQueryable<T>, I suggest you do so. If you can't, you may need to call Cast<T>() or OfType<T>() to create an appropriate IQueryable<T> with...

If i have understood it correctly you want to get all selected parents and all selected children.

You can ignore pretty much all your code, the issue is just this: XDocument people = new XDocument("Persons"); You can't create an XDocument containing a string, you need to add an element: XDocument people = new XDocument( new XElement("Persons", original.XPathSelectElements(xpathFilterDups))); ...

Solution 1: Simplest solution would be DefaultView.ToTable. dt.DefaultView.ToTable(true, "PONumber", "Customer", "Address"); Solution 2 : Another alternative would be using Linq statement to filter distinct rows and then looping them as required. var result = dt.AsEnumerable() .Select(row => new { PONumber = row.Field<string>("PONumber"), Customer = row.Field<string>("Customer"), Address = row.Field<string>("Address") }).Distinct(); Solution...
Your approach doesn't work because you are using ToString on a DataColumn which has no such overload like DateTime. That doesn't work anyway. The only way with the DataTable was if you'd add another string-column with the appropriate format in each row. You should instead use the DataGridViewColumn's DefaultCellStyle: InvestorGridView.Columns(1).DefaultCellStyle.Format...

The biggest optimization would be changing the Contains to a StartsWith. Which would be equivalent to changing from name like '%search%' to name like 'search%'. Otherwise SQLite can't fully use the indexes you placed on the columns and you are basically searching the whole table. // First Name if (!string.IsNullOrEmpty(firstName))...
