Simple solution is to use Array.Copy() method. C# Code 1 2 3 int [] sourceArray = {1,2,3,4,5,6,7,8,9,10}; int [] destinationArray = new int [1]; Array.Copy(sourceArray,3,destinationArray,0,1); VB.NET Code 1 2 3 Dim sourceArray As Integer () = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10} Dim destinationArray As Integer () = New Integer (1) {} Array.Copy(sourceArray, 3, destinationArray, 0, 1)

Windows Forms DataGridView has a built-in event when the DataGridViewCell is resized but missing in WPF. To add an event for the DataGridCell when it is resized, a solution is to add an EventSetter to the DataGridCell style and then set the values of Handler and Event respectively. 1 2 3 4 5 <DataGrid.CellStyle> <Style TargetType= "DataGridCell" > <EventSetter Event= "SizeChanged" Handler= "Cell_SizedChanged" /> </Style> </DataGrid.CellStyle> In your code behind, add definition to the Handler based from the defined style. 1 2 3 4 5 private void Cell_SizedChanged( object sender, SizeChangedEventArgs e) { DataGridCell cell = (DataGridCell)sender; //TODO: Add your code here.... }

Here's how you click an <li> element with data-id attribute. Given that the element's behavior includes navigating to another page. VB.NET 1 2 3 4 5 6 7 8 9 10 11 12 If webBrowser1.Document IsNot Nothing Then Dim elems As HtmlElementCollection = webBrowser1.Document.GetElementsByTagName( "li" ) For Each elem As HtmlElement In elems Dim nameStr As String = elem.GetAttribute( "data-id" ) If ((nameStr IsNot Nothing ) And (nameStr.Length <> 0)) Then If nameStr = "5" Then elem.InvokeMember( "click" ) End If End If Next End If C# 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 if (webBrowser1.Document != null ) { HtmlElementCollection elems = webBrowser1.Document.GetElementsByTagName( "li" ); foreach (HtmlElement elem in elems) { String nameStr = elem.GetAttribute( "data-id" );

Given the task that my client requires me to retrieve all customers and their recent orders made for their report, the solution for this using LINQ is to join two tables namely Customers and Orders . Then the script retrieves the latest order code in the subquery with the condition that it should match with the customer id in the outer query. The subquery also applies arranging the orders made according to recent date and then select the latest using FirstOrDefault() which is the equivalent to Top 1. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 var results = ( from order in _context.Orders join cus in _context.Customers on order.CustomerID equals cus.CustomerID where (order.OrderID == ( from subOrder in _context.Orders where subOrder.CustomerID == order.CustomerID orderby subOrder.OrderDate descending select subOrder.OrderID).FirstOrDefault())

Good day! Here's the C# version of this post. Apply LINQ Grouping and Sum aggregate to a Datatable Object (VB.NET) Code: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 DataTable dt = new DataTable( "tblEntTable" ); dt.Columns.Add( "ID" , typeof ( string )); dt.Columns.Add( "amount" , typeof ( decimal )); dt.Rows.Add( new object [] { "1" , 100.51 }); dt.Rows.Add( new object [] { "1" , 200.52 }); dt.Rows.Add( new object [] { "2" , 500.24 }); dt.Rows.Add( new object [] { "2" , 400.31 }); dt.Rows.Add( new object [] { "3" , 600.88 }); dt.Rows.Add( new object [] { "3" , 700.11 }); var results = ( from orders in dt.AsEnumerable() group orders by orders.Field< string >( "ID" ) into g select new { ID = g.Key,

Hello, In this article, I'll show you two options to get the cell value of excel using C#. Given that you are using VSTO and have referenced the assembly Microsoft.Office.Interop.Excel. 1 2 3 var cellValue = ( string )(xlWorkSheet.Cells[3, 6] as Excel.Range).Value2; //or this var cellValue = xlWorkSheet.get_Range( "F3" , Type.Missing).Value2; Note: xlWorkSheet is an Excel Worksheet object.

Hello, According to MSDN, IEnumerable<T> Interface exposes the enumerator, which supports a simple iteration over a collection of a specified type. Collections such as List<T> implements this interface. For this demo, I created a simple class that implements IEnumerable<string>. You can use concrete types instead of string or ordinary data types. Presented are two classes in different languages (C# and VB.NET) that implements the interface. Notice that in VB.NET, the yield functionality is applied in an Iterator function. C#.NET 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 namespace IEnumerableExample { class Program { static void Main( string [] args) { MessagingApp myObject = new MessagingApp(); foreach ( string item in myObject) { Console.WriteLine(item); } Console.

Given that you have data such as comments/notes/description/address that would comprise at least hundreds of characters and you want to show them on the DataGridView control, you will notice that the text is concatenated and replaced with ellipses. In order to achieve wrapping of text in a DataGridView cell, I achieved it using these steps. 1. Change the WrapMode value to True of a DataGridViewTextBoxColumn's DefaultCellStyle. 2. In my DataBindingComplete event of the DataGridView, set the AutoSizeRowsMode of the DataGridView to AllCells. C# Code private void dgvFormat_DataBindingComplete( object sender, DataGridViewBindingCompleteEventArgs e) { dgvFormat.AutoSizeRowsMode = DataGridViewAutoSizeRowsMode.AllCells; } That's it.. :-)

Sample snippet on getting the three largest values in an array using LINQ. VB.NET 1 2 3 4 5 6 7 8 9 10 11 12 13 Dim rand As New Random() Dim numbers As New List( Of Int32) For index = 1 To 20 Step 1 ' add a list item which is a number from 1 through 100 numbers.Add(rand.Next(1, 100)) Next Dim topThreeLargest = numbers.OrderByDescending(Function(t) t).Take(3) Console.WriteLine( "Top three largest elements in the array: " ) For Each item As String In topThreeLargest Console.WriteLine(item) Next

Here's how you set the first parameter of $.getJSON() which is url using @Url.Action() where GetProductDetails is the action name and Product is the controller name. Make sure to surround it with single quotes. Javascript Code: 1 2 3 4 5 function GetProductData(event) { $.getJSON( '@Url.Action("GetProductDetails","Product")' , function (prod) { alert(prod); }); }

There was a question raised in the forum on how to append query string to a PostbackUrl attribute in an ASP.NET LinkButton inside the template field of a GridView control. To answer that, one possible solution is to set the PostBackUrl with String.Format() method where you can include the desired query string of that url. 1 2 3 4 <asp:LinkButton ID= "lnkProductPage" runat= "server" PostBackUrl= '<%# String.Format("ProductPage.aspx?Id={0}", Eval("ID"))%>' CausesValidation= "false" Text= '<%# Eval("ID")%>' > </asp:LinkButton>
