ForEach Loop in Array (C# / VB.NET)

How to iterate elements of Array using ForEach in .NET (C#)

Here is a simple example of that:

            arString = new string[2];
            arString[0] = "First Element";
            arString[1] = "Second Element";

How to Write Padded (Formatted) Text File using VB.NET/C#

Writing Equi-Spaced Output using C# and VB.NET

Here is a small code to write a multiplication table.

For i1 As Integer = 1 To 20

Console.WriteLine(i1.ToString & " x 12 = " & (i1 * 12).ToString)

Next i1

Have you ever thought it would be better to have it properly aligned. Then use the Padding options (PadeLeft here) to format the output

Private Sub WritePaddedText()

        ' Write a Padded Multiplication Table
        For i1 As Integer = 1 To 20
            Console.WriteLine(i1.ToString.PadLeft(2) & " x  12 = " & (i1 * 12).ToString.PadLeft(3))
        Next i1
    End Sub

Unable to copy file "obj\x86\Debug\*.exe" to "bin\Debug\*.exe". The process cannot access the file 'bin\Debug\*.exe' because it is being used by another process.

To release the file go to the Task Manager and see if the Exe is running in the process Tab. Kill the process and Build the project it should work.

But before that make sure why the Exe was still running in the process even after the application is termninated. It might be due to some malperformance of garbage collection

VB.NET How to Resize the form along with Controls

Windows Form - Resize Controls Dynamically using VB.NET

There would be many occasions you would have come across the need to resize the form to fit some controls/text etc. In the following example we use the combination of LinkLabel and Panel Control to achieve that

Here is the sample form

This is how it needs to be expanded to accomodate the additonal information

I have used a '+/-' hyperlink (LinkLabel Control) to resize the form. (For more info on Link Label : Hyperlink Control in Windows Forms (VB.NET) Application). You can use >> or << etc to be more clear

The controls for Year Founded and Financial Performance are enclosed in a Panel

Add the following code to the LinkClicked event of the LinkLabel

If Panel1.Height = 0 Then
            Panel1.Height = 110
            Me.Height = Me.Height + 110
        Else
            Panel1.Height = 0
            Me.Height = Me.Height - 110

        End If

The form gets re-sized on clicking the hyperlink (it actually toggles)

How to find Difference between two time (Dates) using VB.NET

Difference between two different dates using VB.NET

DATEDIFF function will come handy to find the difference between a set of dates. The snippet given below gets the difference in seconds

Private Sub DateDiffExample()

        Dim dt1 As Date = New Date(2011, 5, 15, 10, 11, 2)
        Dim dt2 As Date = New Date(2011, 5, 15, 10, 12, 22)

        Dim dt3 As Long = DateDiff(DateInterval.Second, dt1, dt2)

    End Sub

You can tweak a bit to get for Minutes or Hours etc by

Private Sub DateDiffExample()

        Dim dt1 As Date = New Date(2011, 5, 15, 10, 11, 2)
        Dim dt2 As Date = New Date(2011, 5, 15, 10, 12, 22)
