You can sort three numbers without an array. But your prof/teacher may have wanted an array-based solution. So put those numbers in an array and you have a solution which can easily handle also four integer's sorting . VB.NET arrays have a Sort-method: Array.Sort(MyIntArr) which sorts your array in ascending …

[ICODE]myPath = HttpContext.Current.Server.MapPath("somePath");[/ICODE] and remember to add reference to [ICODE]System.Web[/ICODE]

There are two ways to do it. First is to wait [CODE=VB.NET]copyProcess.Start("C:\Program Files\Internet Explorer\iediagcmd.exe") copyProcess.WaitForExit(10000) ' Wait until finished or timeout after ten secs[/CODE] for the process to exit. Second is to wait event which a process raises when finished: [CODE=VB.NET]Private WithEvents copyProcess As Process ' Declare process ' Event …

Back to the OP's question. If I do remember right, Explorer won't let you open C:\Users\NN folder unless you're NN. It's a good programming practice not to ask user to have admin rights for your app. It's totally waste of time because standard users do not know admin password and …

You have code outside class and ... quite a few other errors [CODE=C#] using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace Problem8Pg179 { public class GranolaSales { public static void Main() { const int NUMBER_OF_BARS = 12; const double NUMBER_OF_CASES = 5; const double ASSOCIATION_FEES = 0.10; string inputValue; …

You can use built-in Sort method [CODE=C#]// Declare an array with ten elements //int[] a = new int[20]; int[] a = new int[10]; Random rand = new Random(); for (int i = 0; i < 10; i++) a[i] = rand.Next(10000); for (int i = 0; i < 10; i++) Console.WriteLine(a[i]); …

Here's a tip: Show wait cursor: [CODE]Me.Cursor = Cursors.WaitCursor[/CODE] and after the work is done return it to normal: [CODE]Me.Cursor = Cursors.Default[/CODE] If you have a statusbar in your form you may display text: "Loading..." or something like that. And the most important thing. If you have some long lasting …

I didn't quite get that. Is it this you're trying to do: [CODE=VB.NET]With ProgressBar1 .Value = 50 End With With ProgressBar2 .Value = 50 End With[/CODE]to get into [CODE]With Each ProgressBar .Value = 50 End With Each[/CODE]

How do you handle those diacritics or glyphs? As a Latin letters or some other way (like images)? I mean what kind of keyboard you use to write Maldivian? If Maldivian glyphs can be represented as Latin letters (just like Cyrillic letters can be represent), it shouldn't be hard to …

I've used only classic ASP and it had session variables. If asp.NET has similar method, the first thing in secure.aspx page is to check that "session variable". If it's set, let the user continue. If it's not set or not found, use page transfer to move user back to start …

[QUOTE]to keep the MouseLeave event on the panel from firing when another control is crossed? Or another way to accomplish the same?[/QUOTE] You can't prevent that event. But instead of mouse leaving the panel, you should think where the mouse enters. I would assume that the mouse enters a form. …

[QUOTE]the progressbar starts to load until and stops only when process.HasExited[/QUOTE] Process object doesn't raise any events except Exited. So there's no way to know what the process is doing. What sort of process you're dealing with?

Could you please post that part of the code that uses StringBuilder?

With nested controls you must be aware which Controls collection you're dealing with. Also, Panel control doesn't support foreach syntax so you have to use for-loop [CODE=C#]Control c; for (int i=0; i<pnlDeadPcs.Controls.Count; i++) { c = pnlDeadPcs.Controls[i]; if (c is Button) { // Use Button c } } [/CODE] HTH

No. There's not such thing. But you can use Node's Tag property to store extra information [CODE=VB.NET]Dim thisRoot As New TreeNode thisRoot.Tag = "C:\users\myname\My Documents\" . . . Dim rootPath As String rootPath = thisRoot.Tag.ToString()[/CODE] HTH

IMHO the first place to get information is [URL="http://msdn.microsoft.com/en-us/library/w0x726c2.aspx"]MSDN[/URL]. In your case especially [URL="http://msdn.microsoft.com/en-us/library/system.io.aspx"]System.IO Namespace[/URL] and [URL="http://msdn.microsoft.com/en-us/library/system.net.aspx"]System.Net Namespace[/URL]. MSDN is a reference or a documentation of the .NET Framework and not a tutorial but if you're familiar with programming you should find all you need from there. HTH

You should have a different SQL clause depending on your search box. Procedure LoadPeople should start like this [CODE=VB.NET]Dim sqlQuery As String Select Case ComboBox1.SelectedValue.ToString() Case "Name" sqlQuery = "SELECT * FROM reservation ORDER BY Name" Case "Room type" sqlQuery = "SELECT * FROM reservation GROUP BY RoomType" End Select[/CODE]Since …

Use [CODE=C#]Application.DoEvents();[/CODE] before calling [ICODE]Thread.Sleep()[/ICODE] HTH

That's because "eng" and "type" are attributes, not elements. Here's a bit fixed version: [CODE=VB.NET] Dim settings As XmlWriterSettings = New XmlWriterSettings() Dim writer As XmlWriter Dim i As Integer ' i was undeclared variable settings.Indent = True writer = XmlWriter.Create("D:\Translations", settings) ' Begin writing. writer.WriteStartDocument() ' Start tag for …

Have you tried this basic way to do it? [CODE=VB.NET]' Add some items ContextMenuStrip1.Items.Add("First") ContextMenuStrip1.Items.Add("Second") ContextMenuStrip1.Items.Add("Third")[/CODE] and when you handle the ItemClicked event: [CODE=VB.NET]Private Sub ContextMenuStrip1_ItemClicked(sender As Object, e As System.Windows.Forms.ToolStripItemClickedEventArgs) Handles ContextMenuStrip1.ItemClicked Select Case e.ClickedItem.ToString() Case "First" ' Item with text "First" selected Case "Second" ' Item with text …

Could you use a second table (YearTable) to hold year and count information: [CODE]YearCode YearCount 2009 1 2010 2 [/CODE] Now you could [ICODE]SELECT MAX(YearCount) AS YearVal FROM YearTable WHERE YearCode = 2010[/ICODE] Also [ICODE]SELECT MAX(YearCount) AS YearVal FROM YearTable WHERE YearCode = 2011[/ICODE] would return YearVal = DbNull.

You can use InputBox :D Ok, trap some key event in form level: KeyPress, KeyDown or KeyUp. KeyDown or KeyUp might be most flexible choices. HTH

I think that line [ICODE]FullTypeName = Application.ProductName & "." & FormName[/ICODE] goes wrong because you use Application.ProductName which is "SQLtesting".

First, use type casting when you convert text to number: [ICODE]dblYard = CDbl(txtYard.Text)[/ICODE] There are quite a few ways to format doubles as strings.

I suggest comparing checksums of the original file and the possibly corrupted file.
