"character" is to specify, Moves one or more characters.
We can use "word","sentence","textedit".

You must rewrite the logic of finding the "start" and "end".

Hi,

I am newbie to asp.net C#, so I am not sure how to read the data from SQL Express database and validate the user input from the database using asp.net C#. Mostly from book and internet are in VB language. I don't want use login control in asp.net C#. The below is I create the main page myself. In vb,I am ok with it but C# not good.

Anyone can help and any recommended website for asp.net C#?

The bottom is my source code where I have tried to use SQLdataReader:
aspx
<%@ Page Language="C#" MasterPageFile="~/MasterPage.master" AutoEventWireup="true" CodeFile="Default3.aspx.cs" Inherits="Default3" Title="Untitled Page" %>

<asp:Content ID="Content1" ContentPlaceHolderID="head" Runat="Server">
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="Main" Runat="Server">
</asp:Content>
<asp:Content ID="Content3" ContentPlaceHolderID="Navigation" Runat="Server">
</asp:Content>
<asp:Content ID="Content4" ContentPlaceHolderID="Footer" Runat="Server">
</asp:Content>

<asp:Content ID="Content5" runat="server"
contentplaceholderid="RightTopContent">
<asp:Image ID="Image1" runat="server" Height="26px" Width="162px" />
 
Username :<asp:TextBox ID="txtUserName" runat="server"></asp:TextBox>
 
Password :<asp:TextBox ID="txtPassword" runat="server"></asp:TextBox>
 
<asp:Button ID="btnSubmit" runat="server" onclick="btnSubmit_Click"
Text="Login" />
 
</asp:Content>
<asp:Content ID="Content6" runat="server"
contentplaceholderid="RightMiddleContent">
</asp:Content>
<asp:Content ID="Content7" runat="server" contentplaceholderid="MainContent">
</asp:Content>
aspx.cs
protected void btnSubmit_Click(object sender, EventArgs e)
{
string uname = txtUserName.Text;
string pwd = txtPassword.Text;

string connectionString = "Data Source= .\\SQLEXPRESS;"
+ "AttachDbFilename=\"C:\\Documents and Settings\\kathy\\My Documents\\Visual Studio 2008\\WebSites\\WebSite1\\App_Data\\salon.mdf\";"
+ "Integrated Security=True;"
+ "User Instance=True";
SqlConnection myConnection = new SqlConnection(connectionString);
SqlCommand cmd = myConnection.CreateCommand();

cmd.CommandText = "SELECT * FROM [Customer]";
myConnection.Open();

SqlDataReader dr = cmd.ExecuteReader();

while (dr.Read())
{
if (dr.GetOrdinal("UserName").ToString() == txtUserName.Text)
{
Response.Write("Heelo");
//dr.Close();
}
//dr.Close();
myConnection.Close();
}

Check out the <asp:Login /> control (and related), with the only really important event the Authenticate event.

Cannot call multiple web service methods using ASP.NET AJAX at the same time

Domenic Denicola7-Jul-08 1:06

I really can't figure this one out; sorry guys.

I have a pretty-standard WCF service, with a contract something like this:

[ServiceContract(Namespace="http://www.domenicdenicola.com/")]
public interface IMyService
{
	[OperationContract]
	[WebInvoke]
	void PerformBigOperation();

	[OperationContract]
	[WebInvoke]
	int GetProgress();
}

I generate the ASP.NET AJAX proxy class in the usual way:

<asp:ScriptManager ID="ScriptManager" runat="server">
	<Services>
		<asp:ServiceReference Path="MyService.svc" />
	</Services>
</asp:ScriptManager>

I then call them from JavaScript like so:

var service = new www.domenicdenicola.com.IMyService();

function UpdateProgress()
{
	service.GetProgress(function onSuccess(result)
	{
		$get("Status").innerHTML = result + " % complete…";
		setTimeout(UpdateProgress, 1500);
	});
}
function PerformBigOperation()
{
	setTimeout(UpdateProgress, 1500);
	service.PerformBigOperation(function onSuccess(result)
	{
		$get("Status").innerHTML = "Done.";
	});
}

where PerformBigOperation is called upon clicking a button, and Status is the ID of a status  tag.

I also have set Async="True" in my <%@ Page %> directive. (This seems to make no difference.) My web.config contains the following relevant sections:

<system.serviceModel>
	<serviceHostingEnvironment aspNetCompatibilityEnabled="true"/>
	<extensions>
		<behaviorExtensions>
			<add name="enableWebScript" type="(a long string)"/>
		</behaviorExtensions>
		<bindingExtensions>
			<add name="webHttpBinding" type="(a long string)"/>
		</bindingExtensions>
	</extensions>
	<bindings>
		<webHttpBinding/>
	</bindings>
	<behaviors>
		<serviceBehaviors>
			<behavior name="Behavior">
				<serviceMetadata httpGetEnabled="true"/>
				<serviceDebug includeExceptionDetailInFaults="true"/>
				<serviceThrottling maxConcurrentCalls="1000" maxConcurrentSessions="1000"/>
			</behavior>
		</serviceBehaviors>
		<endpointBehaviors>
			<behavior name="EndpointBehavior">
				<enableWebScript/>
			</behavior>
		</endpointBehaviors>
	</behaviors>
	<services>
		<service behaviorConfiguration="Behavior" name="MyService">
			<endpoint address="" binding="webHttpBinding" behaviorConfiguration="EndpointBehavior" contract="IMyService"/>
			<endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/>
		</service>
	</services>
</system.serviceModel>

The problem is, the first call to the service blocks the second one, so GetProgress never returns until after PerformBigOperation is finished, by which point it is, of course, useless. Any ideas!?!

Hi,

Yes I think it’s possible.
Just a quick tip...I feel you better get the data to a DataTable and bind it directly.

For example:

Fill the data to a datatable.
string sConnection = ConfigurationManager.ConnectionStrings["TestDBConnectionString"].ConnectionString;
SqlConnection Con = new SqlConnection(sConnection);
SqlCommand cmd = new SqlCommand();
cmd.Connection = Con;
cmd.CommandType = CommandType.StoredProcedure;
cmd.CommandText = "Employee_Select";
SqlDataAdapter adp = new SqlDataAdapter(cmd);
DataTable dtValues = new DataTable();
adp.Fill(dtValues);

Bind it to gridview.
GridView1.DataSource = dtValues;
GridView1.DataBind();

In the .aspx page
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="false">
<Columns>
<asp:BoundField DataField="EmployeeNumber" HeaderText="Emp. No:" />
<asp:BoundField DataField="Name" HeaderText="Name" />
</Columns>
</asp:GridView>

Hope it solves.
Thx,
Gayani

You can access it by using

HttpContext.Current.Session

.

Tried HttpContext.Current.Session ? Are you writing this in any event which fires before session gets initialized ?

Well can you display your if statement so we can see what is happening, there could be a number of reasons.

What event is your code in?

kathyani6-Jul-08 23:55

6-Jul-08 23:55

This is my code
protected void lnkPrevious_Click(object sender, EventArgs e)
{

if (this.PageNumber ==1)
{
lnkPrevious.Enabled = false;
lnkNext.Enabled = true;
Response.Redirect("pge1.aspx");
}
else
{
this.PageNumber -= 1;
Response.Redirect( "pge"+this.PageNumber.ToString()+".aspx");

}
}

What is page1.aspx?
If it is the current page, Then It will be depend upon the design of the page(if you are not not set the enabled property at design time,by default it will be enabled).
So

kathyani wrote:
lnkPrevious.Enabled = false;

Disable your link button, but

kathyani wrote:
Response.Redirect("pge1.aspx");

will Enable it.
