If you have not yet created the SQL Server database, exit the Web Site Administration tool, use the aspnet_regsql command-line utility to create and configure the database, and then return to this tool to set the provider. "

you have to run aspnet_regsql command from command prompt and chose the database from there for web site configuration.

From Command Prompt >Goto Framework directory > Run aspnet_regsql

C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727>aspnet_regsql

Hi

I am looking for some help from anyone who can show how I can assign a web service to named pipes. My application is a web application where the web service will be in a separate project. The design I need to implement is where the request from the client to server is one pipe where it needs to invoke a process and then down another pipe, the response, a server to client where this invokes a separate application. I am only passing XML data between the two.

In code project, I saw the two articles on NamedPipes, but being a little new to this, I could with some expert help on how to do this, and how to call the Web Service App from Asp.Net.

Can someone help me, please!

So you have a Web Service, a client app, and some other app on the server.

You want the client app to contact the web service, which will then activate the server app, which the client app will be waiting to hear from?

The client, which is an ASP.Net page or my web application, will be waiting to hear from an application, which will on another device via the web service. So, in other words browser, web application, sends XML via web service to another application else where down one pipe, does work, response from this application goes back down another pipe back to my ASP.Net page.

using System;
using System.Data;
using System.Configuration;
using System.Collections;
using System.Web;
using System;
using System.Data;
using System.Configuration;
using System.Web;
using System.Web.Security;
using System.Web.UI;

using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
using System.Data.SqlClient;
using CrystalDecisions.CrystalReports;
using CrystalDecisions.ReportSource;
using CrystalDecisions.Web;

using CrystalDecisions.CrystalReports.Engine;

public partial class _Default : System.Web.UI.Page

SqlConnection con = new SqlConnection();
con.ConnectionString = "data source =SHYLOCK2E935FD7F\\SQLEXPRESS;Initial catalog=StudentDetails ;Integrated Security =true";

}
protected void btnShow_Click(object sender, EventArgs e)
{
SqlConnection con = new SqlConnection();

con.ConnectionString = "datasource=SHYLOCK2E935FD7F\\SQLEXPRESS;Initial catalog=StudentDetails ;Integrated Security =true";
SqlCommand cmd = new SqlCommand();
cmd.Connection = con;
cmd.CommandType = CommandType.Text;
cmd.CommandText = "select c.RollNo,c.StudentName,c.Department,p.feetype,p.amount from studentheader c INNER JOIN studentdetails p on p.Rollno=c.Rollno where c.Rollno=" + TextBox1.Text + "";
DataSet ds = new DataSet();
SqlDataAdapter da = new SqlDataAdapter();
da.SelectCommand = cmd;

da.Fill(ds);

con.Close();
ReportDocument CrystalReport = new ReportDocument();
string reportPath = Server.MapPath("CrystalReport.rpt");
CrystalReport.Load(reportPath);
CrystalReport.SetDataSource(ds);
CrystalReportViewer1.ReportSource = CrystalReport;
CrystalReportViewer1.DataBind();
}

Use the stringbulder to build the string and put debug point to test wheather ur string is formed is the correct one.
for e.g

Dim sbScript as new System.Text.Stringbuilder
sbScript.append("Select eName,eSalary from Emp ")
sbScript.append("where eid=") //Use the single quote after = sign if eid is string
sbScript.append(TextBox1.Text)

cmd.CommandText = sbScript.ToString()

Hope this trick will be helpful to you...

Obviously that code will not work for exe, that was only for image. Becuase for for exe you have to chnage the content type.

Response.ContentType = "application/exe";
