1. Image Slider

Image slider snap shot

Hi, friends in this tutorial i will guide you about how to make a simple image slider in c# using win forms step by step. This application is created using Object Oriented Programming pattern

Step 1.
   Before start the task you need visual studio 2010  which has .net framework 4.0 by default.

Step 2.
   Design the look of Image slider using Toolbox control (left side in visual studio). 
   Remember you need the following controls for this application (Image Slider) :

1. pictureBox1
2. Buttons
3. Radio buttons
4. check boxes
5. Timer 
6. OpenFileDialogue
7. SaveFileDialogue
8. contecxtMenuStrip

After creating your design by drag and drop,  your image slider looks like same as above image.

Step 3.
  Create new CLASS file like this image shown bellow and give that file name 
  ImageSliderRunner.cs

Creating new class file in visual studio

Step 4.
  copy and paste the following code into your ImageSliderRunner.cs file
  
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.IO;
using System.Windows.Forms;
namespace ImageSliderDemo
{
    sealed class ImageSliderRunner
    {
        private static string[] pics;
       
        private static string[] imagePaths;

        public static int Counter = 0;

        public static void SetImages()
        {

            imagePaths = Directory.GetFiles("images");
            ImageSliderRunner.pics = new string[imagePaths.Length];

            for (int i = 0; i < imagePaths.Length; i++)
                 pics[i] = imagePaths[i];

        }

       
        public static string PlaySlides()
        {

            Counter++;
            return pics[Counter];
        }


        public static string InitialPic()
        {
            return pics[0];
        }


        public static string NextImage()
        {

            Counter++;
            return pics[Counter];

        }


        public static string PrevImage()
        {

            Counter--;
            return pics[Counter];
        }


        public static string GetPath(string path)
        {

            return path;
        }


        public static bool ImportImages(string sourceFile , string copeidFile)
        {

            File.Copy(sourceFile, copeidFile);
            
            return true;
        }



        public static int TotalImages()
        {

            return ImageSliderRunner.pics.Length;
           
        }

        public static string RemovePicture()
        {
            
                return ImageSliderRunner.pics[Counter];
           
        }


        public static string GetCurrentPicture()
        {

            return ImageSliderRunner.pics[Counter];
        }


      
        public static bool DoSavePicture(string picture, string DesPath)
        {

            File.Copy(picture, DesPath);
            return true;

        }


        public static string SavePerference(string resource)
        {

            File.WriteAllText("storePrefe.txt", resource);
            return resource;
        }


        public static string GetPreference()
        {

            string[] pref = File.ReadAllLines("storePrefe.txt");
            return pref[0];

        }
    }

}

Step 5.
   Now open your Form1.cs [Design] file which contains your all controls means your
   image slider design (buttons, UI etc). after open it your file look likes as bellow:

Form1.cs [Design] file selected in visual studio

Step 6.
  at this point you have to create events in code behind file of this  Form1.cs [Design]  file
  but remember you must create events by double clicking at > this button and you will 
  notice that event can be seen at right side in toolbox which marked as red circle.

Creating an event in visual studio

Step 7.
  When you double click at < button in step 6. the click event has created and along this it's
  code behind file (Form1.css) also created as bellow. Remember some points here which is

1.   This is the code behind file Form1.cs which contains your all registered events and response the user interaction such as NEXT image PREV image etc.
2. This events called the methods from class file which is mentioned in Step 4. 
3. All the main logic is written in that class file ImageSliderRunner.cs

Code behind file with event creation

Step 8. (final step)
  Copy and paste the following code into your code behind file (Form1.css) which is mentioned
  in Step 7.

        {

            ImageSliderRunner.SetImages();

        }   
              

    }
}

REMEMBER:

• Above code will work perfect 
• But you MUST explicitly registered ALL events which is defined in above code such as   [private void RemovePics(object sender, EventArgs e) ] if you will not do that. the apps must be generate errors.
• Do not forget the create 1 files and 1 folder
• create folder named [images] inside the bin -> debug folder because when you add images in slider every time that image copy in that folder
• create .txt file named [storePrefe.txt] inside  bin -> debug.

FINALLY IF YOU WENT RIGHT THE IMAGE SLIDER WILL PERFECT WORK FOR YOU.

1. Any image can be added and removed from slider
2. Any image can be saved from slider
3. Produced slide show next play and prev images

THANKS I HOPE YOU HAVE ENJOYED CODE
