Web Services in ASP.NET

-
A Web Service is programmable application logic accessible via standard Web protocols. One of these Web protocols is the Simple Object Access Protocol (SOAP). SOAP is a W3C submitted note (as of May 2000) that uses standards based technologies (XML for data description and HTTP for transport) to encode and transmit application data.
Consumers of a Web Service do not need to know anything about the platform, object model, or programming language used to implement the service; they only need to understand how to send and receive SOAP messages (HTTP and XML).

Try simple code :

ASPX :->


<html xmlns="http://www.w3.org/1999/xhtml">
<
head runat="server"><title></title></
head><
body><form id="form1" runat="server"><div><asp:GridView ID="GridView1" runat="server"><Columns><asp:BoundField DataField="id" HeaderText="ID" /><asp:BoundField DataField="f_name" HeaderText="Firts name" /><asp:BoundField DataField="adds" HeaderText="ADDS" /></Columns></asp:GridView><asp:Button ID="Button1" runat="server" Text="Click" onclick="Button1_Click" /></div></form></
body></
html>

CS ->

using System;using System.Collections.Generic;using System.Linq;using System.Web;using System.Web.UI;using System.Web.UI.WebControls;using webServiceTrial;namespace webServiceTrial{

public partial class _Default : System.Web.UI.Page{
protected void Page_Load(object sender, EventArgs e){
}

protected void Button1_Click(object sender, EventArgs e){
webServiceTrial.
WebService1 wrr = new webServiceTrial.WebService1();GridView1.DataSource = wrr.getDetails();
GridView1.DataBind();
}
}
}


WebService asmx :-?


using System.Web.Services;using System.Data;using System.Data.Sql;using System.Data.SqlClient;namespace webServiceTrial{

/// <summary>/// Summary description for WebService1/// </summary>[WebService(Namespace = "http://tempuri.org/")][
WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)][System.ComponentModel.
ToolboxItem(false)]
// To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line. // [System.Web.Script.Services.ScriptService]public class WebService1 : System.Web.Services.WebService{
[WebMethod]
public string HelloWorld(){

return "Hello World";}
[
WebMethod]
public DataSet getDetails(){

SqlConnection conn;
SqlDataAdapter myDataAdapter;
DataSet myDataSet;
const string cmdString = "Select * From Info";conn =
new SqlConnection("Data Source=ADS;Initial Catalog=TestApp;Persist Security Info=True;User ID=Nihar.Kulkarni;Password=bflmcd");myDataAdapter =
new SqlDataAdapter(cmdString, conn);myDataSet =
new DataSet();myDataAdapter.Fill(myDataSet,
"Info");
return myDataSet;
}
}
}

Add Serial no in crystal report without coding

Image
Adding a serial number in grouping without any code. I have placed the step by step screenshots which will explain easily how to do it.   1) Add a new field in Running Total Fields in Field Explorer   Give a proper name to your Running total name. For example I have choosen here RTotal0. Now categorize based on which field in database you want to summarize it. Next is as we want serial number select count. If you want your serial number to start again from the start when the value in the group changes then select on change of group and specify the grouping name else keep the default value.   Smaple Preview of the Design View of Report where I Have added SRNo column at the start in grouping section.

We used this title for describing technologies , we are working in. Here we will see "  How to store files in oracle database using c# ?   " Step 1:           Use file uploader controller to browse directories. Step 2:          Before uploading file or its path , we need to understand BLOB of Oracle          BLOB  ( Binary Large Objects ) :                                                    File content store in binary format.In Oracle , BLOB and    CLOB  (Character Large Object) used.Technically BLOB prefered.For more info regarding BLOB click here  . Step 3 :        In C# , use System.IO namespace for file operations.     Step 4:         string path = FileUpload1.PostedFile.FileName.ToString();         string FileName = FileUpload1.FileName.ToString();         string FileSize = FileUpload1.PostedFile.ContentLength.ToString();         string FileContent = FileUpload1.PostedFile.ContentType.ToString();         string filename = Path.GetFileName(path
