Update/Upgrade Solution
The Update-SPSolution cmdlet upgrades a deployed SharePoint solution in the farm. Use this cmdlet only if a new solution contains the same set of files and features as the deployed solution. If files and features are different, the solution must be retracted and redeployed by using the Uninstall-SPSolution and Install-SPSolution cmdlets, respectively

Bar Code in Sharepoint

Bar Code Feature :- We have two option to enable Bar Code Feature in Document library 

1. Out Of the Box Feature 

2. Custom Programmatically

1. Use the Information Management Policy Feature to enable bar code on documents by Out Of the Box Feature

 Go to Document Library >>Library Settings>>Click on Information Management Policy >>

there are many option >> Select BarCode Checkbox >> Click Ok >> ModifiView >> Add Two Bar Codes Columns in View >>Click OK

Now Add documents in documents library Bar Code will  come automatically.

2. Using Programmatically

Enable the Feature On Document Library and use the below code for custom Bar Codes

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using Microsoft.SharePoint;
using System.Drawing;
using Microsoft.Office.RecordsManagement.PolicyFeatures;

namespace SetBarCodeValue
{
    class Program
    {
        static void Main(string[] args)
        {
            //Define the parameter values: Site collection URL
            string siteURL = "http://example/sites/siteCOllectionName";

            using(SPSite site=new SPSite(siteURL))
            {
                using (SPWeb web = site.RootWeb)
                  {
                      //Get a document library
                      SPList list = web.Lists["Design Documents"];
                      //Get an Item
                      SPListItem item = list.Items[0];

                      //Set Bar code value
                      Image img;
                      string barCodeValue = "700";
                      Barcode.ProvisionBarcodeWithValue(item, true, ref barCodeValue, out img);
                      Barcode.SetBarcodePreview(item);
                      item.Update();                    

                     //Print a message
                     Console.WriteLine("Bar code has been Updated!");
                   }
            }

            //Pause
            Console.ReadLine();

Could not load file or assembly '$SharePoint.Project.AssemblyFullName$' or one of its dependencies

Error=Could not load file or assembly '$SharePoint.Project.AssemblyFullName$' or one of its dependencies. The system cannot find the file specified.



Solution:--


The fix is simple, do the following:

1.  Open your project file .csproj  Edit the .csproj file in NotePad
2.  Find the PropertyGroup nodes.
3.  Add a new PropertyGroup node.
<PropertyGroup>
<TokenReplacementFileExtensions>ashx</TokenReplacementFileExtensions>
</PropertyGroup>
4.  Re-Open your project file

HTTPHandler in Sharepoint

1.Create empty project
2.Add HTTPHandler class from Teamplate if not exist then create manually
3.Open .asxh file paste the below code as per you project Name and Class name

<%@ Assembly Name="$SharePoint.Project.AssemblyFullName$" %>
<%@ WebHandler Language="C#" CodeBehind="FileUploader.ashx.cs" Class="SharePointProject1Test.Layouts.SharePointProject1Test.FileUploader" %>

and .ashx.cs code like below


using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.IO;
using Microsoft.SharePoint;
namespace SharePointProject1Test.Layouts.SharePointProject1Test
{
    /// <summary>
    /// Summary description for FileUploader
    /// </summary>
    ///
 
    public class FileUploader : IHttpHandler
    {

        public void ProcessRequest(HttpContext context)
        {
         
            if (context.Request.Files.Count > 0)
            {
                HttpFileCollection files = context.Request.Files;
                for (int i = 0; i < files.Count; i++)
                {
                    HttpPostedFile file = files[i];
                    AddFile(file.InputStream,file.FileName);
                 
                }
                context.Response.ContentType = "text/plain";
                context.Response.Write("File Uploaded Successfully!");
            }

        }

        public bool IsReusable
        {
            get
            {
                return false;
            }
        }



        public static void AddFile(Stream inputStream,string fileName)
        {
            SPSecurity.RunWithElevatedPrivileges(delegate() {

            using (SPSite site = new SPSite("http://siteName"))
            {
                site.AllowUnsafeUpdates = true;
                using (SPWeb web = site.OpenWeb())
                {
                    web.AllowUnsafeUpdates = true;
                    byte[] bytes = StreamToByteArray(inputStream);
                    SPFolder myLibrary = web.Folders["Documents_test"];
                    SPFile spfile = myLibrary.Files.Add(fileName, bytes, true);
                    myLibrary.Update();
                    web.AllowUnsafeUpdates = false;
                }
                site.AllowUnsafeUpdates = false;

            }
            });
        }
        public static byte[] StreamToByteArray(Stream inputStream)
        {
            byte[] bytes = new byte[16384];
            using (MemoryStream memoryStream = new MemoryStream())
            {
                int count;
                while ((count = inputStream.Read(bytes, 0, bytes.Length)) > 0)
                {
                    memoryStream.Write(bytes, 0, count);
                }
                return memoryStream.ToArray();
            }
        }
    }
}



4.In the Solution Explorer, click the .ashx file and in the Properties pane, set the Build Action to Content.
5. In the Solution Explorer, click the .ashx.cs file and in the Properties pane, set the Build Action to Compile.
6. Now we need to Save and Close the solution.
7. Edit the .csproj file and add the following text to a PropertyGroup,

<PropertyGroup>
<TokenReplacementFileExtensions>ashx</TokenReplacementFileExtensions>
</PropertyGroup>

8. and reload your project in Visual Studio.
9. test the HTTPHandler open browser and paste url like below
 http://SiteName/_Layouts/15/SharePointProject1Test/FileUploader.ashx
9. now HTTPHandler will catch the event and give a message
10. To call HTTPHandler in JQuery/JavaScript paste the code in your Visua webpart / applicationpage / in Content Editor Webpart like below

<script src="/_layouts/15/SharePointProject1Test/jquery-1.4.1.min.js"></script>

<script type="text/javascript">
    $(document).ready(function () {
        $("#btnUpload").click(function () {

            uploadfile();


        });
    });

    function uploadfile() {
        var bannerImage = $("#fupload").val();

        if (bannerImage) {
            var file = document.getElementById('fupload').files[0];
            var formData = new FormData();
            formData.append(file.name, file);
            var xhr = new XMLHttpRequest();
            var url = "/_Layouts/15/SharePointProject1Test/FileUploader.ashx";
            xhr.open('POST', url, true);
            xhr.onload = function (e) {
                var response = $.parseJSON(e.target.response);
alert(response);
           
            };

            xhr.send(formData);  // multipart/form-data

        }
    }
</script>
