My Fizz Buzz Solution

My Fizz Buzz Solution

Solution 1: Using Ternary Operator

            for (int i = 1; i < 101; i++)
            {
                string result = "";
                result = i % 3 == 0 ? "Fizz" : ""; // check if i is divisible by 3
                result += i % 5 == 0 ? "Buzz" : "";// check if i is divisible by 5
                Console.Write("\n" + i.ToString() + " - " + result);
            }

Solution 2: Using IF Operator

            for (int i = 1; i < 101; i++)
            {
                string result = "";
                if (i % 3 == 0) // check if i is divisible by 3
                {
                    //give result the value fizz
                    result = "Fizz"; 
                }
                if (i % 5 == 0) // check if i is divisible by 5
                {
                    //gets the value of result and add to the buzz value giving an output of fizz or fizzbuzz
                    result += "Buzz"; 
                }
                //show result;
                Console.Write(" \n" + i.ToString() + " - " + result);

Prevent a Class to be inherited C#

The sealed can be used to prevent a class to be inherited.

sample:
    sealed class FileClass
    {
        sealed FileClass(string filepath)
        {
            Filepath = filepath;
        }
   
        private string _filepath;
        public string Filepath
        {
            get { return _filepath;}
            set { _filepath = Filepath; }
        }
    }

Display All Server Files in Server using C# and ASP.NET

DirectoryInfo di = newDirectoryInfo(Server.MapPath("/"));

FileInfo[] fi = di.GetFiles();

fi = di.GetFiles("*.*");

foreach (FileInfo fi1 in di.GetFiles())

{

Response.Write( fi1.FullName.ToString());

Response.Write("<br />");

}

Cross-Page Posting ASP .NET

Make 2 forms name it page1.aspx and page2.aspx

on page1.aspx:

Add a TextBox and Button Control

Go to the Button Control Properties and set the PostbackUrl = "~/page2.aspx"

on Page2.aspx:

Add a Label Control and on the Page_Load Event add this following code.

protectedvoidPage_Load(objectsender, EventArgs e)

{

if (PreviousPage != null)

{

if (PreviousPage.IsCrossPagePostBack == true)

{

Label1.Text = "Cross-page post.";

TextBox tb = (TextBox)PreviousPage.FindControl("TextBox1");

this.Title = tb.Text;

}

}

else

{

Label1.Text = "You are not allowed to access this page!";

}

}

Backup MySQL Database to a file

Backup MySQL Database to a file

Backing up your database is a very important system administration task, and should generally be run from a cron job at scheduled intervals. We will use the mysqldump utility included with mysql to dump the contents of the database to a text file that can be easily re-imported.

Syntax:

mysqldump -h localhost -u root -pmypassword databasename > dumpfile.sql

Example:

mysqldump -h localhost -u root -p2Uad7as9 database01 > dumpfile.sql

This will give you a text file containing all the commands required to recreate the database.

VB.NET Office Automation FAQ

I saw this article on a forum, i think it is a very useful article regarding Office Automation

This FAQ 101 is a listing of handy links for getting started with .NET Automation/Interoperation of Microsoft Office programs such as Excel, Word, Access or Outlook.

The first place to start learning about how to integrate MS Office programs into your .NET application is the tutorial Automating Office Programs with VB.NET. It discusses what you need to know to get started, as well as addressing some of the difficulties with .NET Automation such as execution speed and deployment issues. If you are new to .NET Interoperation/Automation, then this link is a good place for you to begin.

For articles on how to fully utilize the Excel object model, Word, and Outlook please check out the following links:

(1) Understanding the Excel Object Model from a .NET Developer's Perspective
(2) Understanding the Word Object Model from a .NET Developer's Perspective
(3) Programming Microsoft Outlook with Visual Studio .NET

(We still lack a resource for utilizing the Access object model in .NET, so if someone knows of a good source, please send me a private message and we will be glad to add it.)

Some advanced forums on MS Office programming include:

(1) .NET Office Automation (XVBT)
(2) Visual Studio Tools for Office Forum (MSDN)
(3) COM Add-ins Forum (MSDN)
(4) Interoperation / Office Integration (XDNT)

Microsoft Office Programs are still COM ActiveX Servers, so the best help regarding specific commands or techniques can be often found in the VBA Forums. If your question is .NET-specific, please place your question in the .NET Office Automation forum. But if your question regards the Microsoft Office object model, as called from VBA or Visual Basic 6.0, then the following VBA/VB6 Office Integration forums can be your best bet:

(1) VBA / Office Integration forum (XVBT)
(2) Excel VBA forum (XVBT)

For some general articles regarding MS Office Interoperation from your .NET application, see the following links:

(1) Automating Office Programs with VB.NET
(2) Creating Office Managed COM Add-Ins with Visual Studio .NET
(3) HOWTO: Run Office Macros by Using Automation from Visual Basic
(4) Develop Microsoft Office Solutions with Visual Studio .NET

For articles dealing with execution or deployment issues and problems:

(1) Office Application Does Not Quit After Automation from VS.NET Client
(2) Microsoft Office XP PIAs Are Available for Download
(3) Office XP Primary Interop Assemblies Known Issues

XOR Encryption in VB

Public Function XOREncryption(CodeKey As String, DataIn As String) As String
Dim lonDataPtr As Long
Dim strDataOut As String
Dim intXOrValue1 As Integer, intXOrValue2 As Integer

For lonDataPtr = 1 To Len(DataIn)
'The first value to be XOr-ed comes from
' the data to be encrypted
intXOrValue1 = Asc(Mid$(DataIn, lonDataPtr, 1))
'The second value comes from the code ke
' y
intXOrValue2 = Asc(Mid$(CodeKey, ((lonDataPtr Mod Len(CodeKey)) + 1), 1))
strDataOut = strDataOut + chr(intXOrValue1 XOr intXOrValue2)
Next lonDataPtr
XOREncryption = strDataOut
End Function

'USAGE
Private Sub cmdEncryptdecrypt_Click()
Dim strCodeKey As String
