Consuming Webserive in DOTNET C#.net C sharp .net

Here I am consuming test webservice of Meeseva

Lets Create a sample Application

I am taking a DropDown to check whether the user having Income Certificate or not. If so the certificate number is supplied to our application and after pressing getData button the details of the certificate are populated and shown in our application.

To do this lets create our design page i.e., income.aspx page..

Create a panel with the controls:

 <asp:Panel ID="income_panel" runat="server">
                <table>
                    <tr>
                        <td colspan="2" align="center" style="font-size: 20px; font-weight: bold; color: darkblue">Consuming Web Service

Now Lets create our CS page with the code behind for each control:

The CS Code is

 protected void Page_Load(object sender, EventArgs e)
    {
        lbl_inc_cer.Visible = false;
        txt_inc.Visible = false;
        income_panel.Visible = false;

        lbl_inc_cer_no.Visible = false;

        lbl_inc_msg.Text = "";

        btn_income.Visible = false;
    }

    protected void ddl_income_SelectedIndexChanged(object sender, EventArgs e)
    {
        if (ddl_income.SelectedValue == "Y")
        {
            lbl_inc_cer.Visible = true;
            txt_inc.Visible = true;
            income_panel.Visible = true;
         
            lbl_inc_cer_no.Visible = true;

            lbl_inc_msg.Text = "";
        
            btn_income.Visible = true;
        }
        else
        {
            lbl_inc_cer.Visible = false;
            txt_inc.Visible = false;
            income_panel.Visible = false;
           
            lbl_inc_cer_no.Visible = false;

            lbl_inc_msg.Text = "";
         
            btn_income.Visible = false;
        }
    }

    protected void btn_income_Click(object sender, EventArgs e)
    {
        this.Validate();
        if (!this.IsValid) return;
        Get_service_data();
        div_inc_online.Visible = true;
        //string mobile = Session["mobileno"].ToString();
        string mobile = hid_mobile.Value.ToString();
     
    }

    public void Get_service_data()
    {
        XmlDocument xmldoc = new XmlDocument();
        string uname, pwd;
        uname = "APCET";
        pwd = "************"; // Provide the Password Here

  IncomeService.MeeSevaTransactions CI = new IncomeService.MeeSevaTransactions();


        if (txt_inc.Text == "")
        {
            lbl_inc_msg.Text = "Certificate Number not given";
            return;
        }
        else if (txt_inc.Text != "")
        {
            string inc_cer_no = txt_inc.Text;
            string response;
            try
            {
                response = CI.GetDetailsByAppNo(inc_cer_no, uname, pwd);
                xmldoc.LoadXml(response);
                //Response.Write("meeseva income Response:" + response.ToString().Trim());

            }
            catch (Exception ex)
            {
                // Response.Write("Meeseva Service Error" + ex.Message.ToString());
                ScriptManager.RegisterClientScriptBlock(this, this.GetType(), "alertMessage", "alert('Not Fetching the Data from Service.Please try again.')", true);
            
                div_inc_online.Visible = false;


            }

            if (xmldoc.SelectSingleNode("//Application_Number") != null)
            {
                if (xmldoc.SelectSingleNode("//Applicant_Name") != null)
                    lbl_inc_name.Text = xmldoc.SelectSingleNode("//Applicant_Name").InnerText;
                if (xmldoc.SelectSingleNode("//FatHus_Name") != null)
                    lbl_inc_fname.Text = xmldoc.SelectSingleNode("//FatHus_Name").InnerText;
                if (xmldoc.SelectSingleNode("//Date_Of_Birth") != null)
                    lbl_inc_dob.Text = xmldoc.SelectSingleNode("//Date_Of_Birth").InnerText;
                if (xmldoc.SelectSingleNode("//Application_Number") != null)
                    lbl_inc_cer_no.Text = xmldoc.SelectSingleNode("//Application_Number").InnerText;
                if (xmldoc.SelectSingleNode("//Total_Income") != null)
                    lbl_inc_inc.Text = xmldoc.SelectSingleNode("//Total_Income").InnerText;

                //Send OTP
                string mobile = hid_mobile.Value.ToString();
                    
            }
            else
            {
                ScriptManager.RegisterClientScriptBlock(this, this.GetType(), "alertMessage", "alert('No Data Available .')", true);

            }
        }


    }

So Now the IncomeService is to be included in our Project To do this follow the steps

Adding a Web Service Reference in the ASP.Net Web Application

The most important task when consuming a Web Service in an ASP.Net Web Application is adding the Web Service reference into the ASP.Net web application. So how to add it? Let us see the procedure.

Right-click on the ASP.Net Web Application and click on "Add Service Reference" as in the following:

 

 Now Give the URL provided for you in the following dialog BOX

 After Providing the URL click Go, the service is populated in the below Dialog where the services are shown.. And provide a Namespace , Here I have given as "IncomeService"

Click on Advanced Button, 

Click On Add Web Reference button in the advanced dialog box ,

Click the AddReference Button, You will get a new web reference in Solution Explorer

As shown in above Picture, Now Run the Program note that the Same Webservice name used in our CS page Which was highlighted in CS Code i.e., IncomeService

How to change the root password for MySQL in XAMPP

Method 1: reset XAMPP MySQL root password through web interface:

After you started your XAMPP server, go to the browser and type the URL http://localhost/security/ (incase you’ve modified XAMPP server port, you need to include that port number also in previous URL). The security page will be shown where you can change the root password for MySQL. This will update the phpMyAdmin config also.

Method 2: reset XAMPP MySQL root password through SQL update:

1. Start the Apache Server and MySQL instances from the XAMPP control panel.
2. After the server started, open any web browser and give http://localhost:8090/phpmyadmin/ (if you are running XAMPP on 8090 port). This will open the phpMyAdmin interface. Using this interface we can manager the MySQL server from the web browser.
3. In the phpMyAdmin window, select SQL tab from the right panel. This will open the SQL tab where we can run the SQL queries.
4. Now type the following query in the textarea and click Go
   UPDATE mysql.user SET Password=PASSWORD('password') WHERE User='root'; FLUSH PRIVILEGES;
5. Now you will see a message saying that the query has been executed successfully.
6. If you refresh the page, you will be getting a error message. This is because the phpMyAdmin configuration file is not aware of our newly set root passoword. To do this we have to modify the phpMyAdmin config file.
7. Open the file [XAMPP Installation Path] / phpmyadmin / config.inc.php in your favorite text editor.
8. Search for the string $cfg\['Servers'\]\[$i\]['password'] = ''; and change it to like this, $cfg\['Servers'\]\[$i\]['password'] = 'password'; Here the ‘password’ is what we set to the root user using the SQL query.
9. Now all set to go. Save the config.inc.php file and restart the XAMPP server.

Method 3: reset XAMPP MySQL root password through Command Prompt

Set the mysql/bin folder path to the environment variables $path and $temp in computer

Run the mysql in xamp server.

and execute the following command in command prompt (Don't forget to choose 'Run as Administrator' option while selecting command prompt)

c:\>mysqladmin.exe -u root password root_password (provide your root_password).

All set, now connect to mysql using the following command

c:\>mysql -u root -p

Enter password: *********
